64887- (54)Title: FINE ADJUSTMENT MECHANISM FOR A TOOLHOLDER (57) Abstract The present invention relates to a milling cutter (10) having a cutter body (12) and a plurality of replaceable tool cartridges (16) circumferentially spaced about the outer periphery of the cutter body. An adjustment mechanism permits 56.
adjustment of the tool cartridges (16) in the direction parallel to the axis of rotation of the cutter 58 body The adjustment mechanism includes an adjustment screw (52) threaded into a corresponding bore (54) in the cutter body The 44head (56) of the adjustment screw (52) projects 16 into an inclined throughbore (60) in tool car- 64 tridge When the adjustment screw (52) is turned, the head (56) of the screw bears against the inner surface of the throughbore (60) causing the tool cartridge (16) to be axially displaced. A locking screw (62) is tightened to secure the tool cartridge (16) in place after it has been adjusted.
WO 92/20500 PCT/CS91/08067 -1- FINE AD7JSTMENT MECHANISM FOR A TOOLHOLDER FIELD OF THE INVENTION The present invention relates generally to an adjustable toolholder, and more particularly to an adjustment mechanism for adjusting the toolholder in the axial direction.
BACKGROUND OF THE INVENTION In any metalworking operation, it is critical to adjust the position of the cutting tool relative to the workpiece in order to obtain an accurate cut, particularly with tools having multiple inserts simultaneously engaging the workpiece, such as milling cutters.
One type of milling cutter which has been used in the past comprises a generally cylindrical cutter body and a plurality of replaceable cartridges adapted to be mounted to the cutter body for holding the cutting inserts. The cartridges are normally adjustable parallel to the axis of rotation of the cutter body to adjust face run-out. That is, the cutting edges of the inserts can be adjusted to a common plane. If the inserts are not adjusted to a common plane, only the forwardmost insert will be cutting. Not only does this condition affect the quality of the finish, but also reduces tool life. For high quality finishes, the face run-out of the cutting inserts must be adjusted to within two-ten thousandths of an inch. Previously, this adjustment has been WO 92/20500 I»Cr/US91/08067 -2obtained by unclamping the tool cartridge, manually positioning the cartridge, and then reclamping the cartridge after the adjustment is complete. This process is relatively cumbersome and time consuming.
Further, with this type of adjustment there is a tendency of the tool cartridge to slip during tightening of the clamping mechanism.
SUMMARY AND OBJECTS OF THE INVENTION The present invention provides a method and apparatus for making fine adjustment to the position of the cutting insert in the axial direction. At least one toolholder having an insert seat formed therein is mounted to a support block. The removable toolholder is held in place by a locking screw. Adjustment in the axial direction is provided by an adjusting screw having a rounded head which cooperates with an inclined throughbore extending through the toolholder. The axis of the adjusting screw lies in a plane perpendicular to the direction of adjustment. As the screw is turned in, the rounded head engages the forward side of the throughbore and urges the toolholder forwardly. When the adjusting screw is turned out, the rounded head engages the back side of the throughbore and urges the toolholder rearwardly. Once the cutting edge of the insert is properly adjusted, the locking screw can be tightened to clamp the toolholder in place. The rounded head of the adjusting screw acts as a positive stop to prevent the toolholder from slipping during tightening of the locking screw.
Based on the foregoing, it is a primary object of the present invention to provide a toolholder having positive adjustment means for adjusting the axial position of the tool insert relative to the tool body.
Another object of the present invention is to provide an adjustment mechanism for a toolholder which allows fine adjustment of the cutting edge of the WO 92/20500 l’ICT/LS91/08067 -3inserts to within two-ten thousandths of an inch to produce a high quality finish.
Still another object of the present invention is to provide a fine adjustment mechanism which can be readily adjusted to assure longer tool life.
Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings which are merely illustrative of such invention, BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a milling cutter incorporating the adjustment mechanism of the present invention; Figure 2 is a side elevation view of the same milling cutter; Figure 3 is a bottom plan view of the milling cutter; Figure 4 is a partial section view of the milling cutter with the tool cartridge shown in elevation; Figure 5 is another partial section view of the milling cutter with the tool cartridge shown in elevation; and Figure 6 is a partial section view of the milling cutter with the tool cartridge shown in crosssection.
DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings, and particularly to Figure 1, a toolholder incorporating the adjustment mechanism of the present invention is shown therein and indicated generally by the numeral The toolholder 10 of the illustrated embodiment comprises a milling cutter, although the use of the present invention is not so limited. The present invention can also be used, for example, in turning or boring tools, as well as a variety of milling tools.
WO 92/20500 P’CT/ US91/0 806 7 -4- The milling cutter 10 is adapted to be mounted to a spindle of a milling machine. The milling cutter 10 includes a generally cylindrical cutter body 12 adapted to be mounted to the forward end of a spindle adapter. The spindle adapter typically includes a tapered rear portion that inserts into a tapered cavity in the machine spindle. The cutter body 12 is adapted to carry a plurality of replaceable tool cartridges 16 that hold carbide cutting inserts 18.
The cutting inserts 18 project from the forward end of the cutter body 12 and include a cutting edge adapted to engage the workpiece. The cutter body 12 and tool cartridges 16 are provided with means to adjust the axial position of the cartridge 1( so as to position the cutting edges 20 of the inserts 18 to a common plane.
The cutter body 12 is generally cylindrical in form and includes an opening 24 in the central portion 22 to receive the spindle adapter. The cutter body 12 is held on the spindle adapter by a large screw (not shown) which threads into the end of the spindle adapter. A plurality of tool recesses 30 is formt- in the outer periphery of the cutter body 12. Each tool recess 30 includes first and second tool reference surfaces 32 and 34 respectively. The first tool reference surface 32 lies generally perpendicular to a radius of the cutter body. The second tool reference surface 34 lies generally parallel to a radius of the cutter body 12. Both the first and second tool reference surfaces 32 and 34 lie in planes extending parallel to the axis of the cutter body 12. The first and second tool reference surfaces 32 and 34 preferably form a 90 degree angle with respect to one another.
As previously indicated, the cutter body 12 is adapted to carry a plurality of replaceable tool cartridges 16. Each tool cartridge 16 includes a forward portion 40 formed with a recessed insert seat W\O 92/20500 PCT/US91/08067 42 and a rearward portion 44. Each cartridge also includes first and second abutment surfaces 46 and 48 respectively, which lie at a 90 degree angle with respect to one another. The first abutment surface 46 is adapted to mount against a first tool reference surface 32 of the cutter body 12. The second abutment surface 48 mounts against a second tool reference surface 34. Thus, it will be appreciated that the cooperation of the first and second tool reference surfaces 32 and 34 with the first and second abutment surfaces 46 and 48 function to accurately position the tool cartridge 18 in the radial and tangential directions.
To adjust the tool cartridge 16 in the axial direction, the present invention employs an adjusting screw 52 that screws into an adjusti.ng screw h< Le 54 in the cutter body 12. The axis of the adjusting screw hole 54, and thus the adjusting screw 52 is coincident with a radius extending from the center of the cutter body 12. The head 56 of the screw 52 is generally spherical in form and includes a hex socket 58 adapted to receive an alien wrench. An inclined throughbore 60 is formed in the rearward portion 44 of the tool cartridge 16 and is positioned to overlie the adjusting screw hole 54. The throughbore 60 is inclined slightly in the axial direction as shown best in Figure 4, the angle of inclination being exaggerated somewhat to better illustrate the invention. The angle of inclination is actually between approximately 1 and 5 degrees. The head 56 of the adjustment screw 52 extends into the inclined throughbore 60 when the tool cartridge 16 is mounted to the cutter body 12. The head 56 of the adjustment screw 52 is very nearly the same size as the diameter of the throughbore 60. When the adjusting screw 52 is turned inwardly, the spherical head 56 bears against the forward side of the WO 92/20500 i,,cr/I-,sq /ow", -6inclined throughbore 60 and urges the tool cartridge 16 forwardly. Conversely, when the adjusting screw 52 is turned out, the spherical head 56 bears against the back portion of the inclined throughbore 60 and urges the tool cartridge 16 rearwardly. The cooperation of the spherical head 56 with the inner surface of the inclined throughbore 60 thus provides adjustment in both the forward and rearward axial directions. A locking screw 62, having a conical head, secures the tool cartridge 16 in the adjusted position. The locking screw 62 extends through a clearance opening 64 in the rear portion of the tool cartridge 16 and is threaded into a locking screw hole 66 (See Fig. 1) in the cutter body 12. The clearance opening 64 is larger than the shaft of the locking screw 62 to allow room for adjustments and includes a conical shaped counterbore 65. The locking screw 62 should preferably be disposed at an approximate 45 degree angle to both the first and second tool reference surfaces 32 and 34 so that the tool cartridge 16 will be firmly pressed against those surfaces when the locking screw 62 is tightened. The centerline of the clearance opening 64 should be positioned such that it will lie rearwardly of the centerline of the locking screw 62 throughout the adjustment range of the cartridge 16. As a result, the conical head of the screw will initially contact the rearmost portion of the counterbore 65 to urge the cartridge against the adjustment screw 52. Further, tightening will cause the screw to bend until the head of the screw 62 is seated firmly in the counterbore as shown in Figure 6. To use the milling cutter 10 of the present invention, the cutting inserts 18 are mounted on tool cartridges 16 which are, in turn, mounted on the cutter body 12. The locking screws 62 are tightened sufficiently to hold the tool cartridges 16 in place in the absence of an applied force, but to permit them to WO 92/20500 PC]'/US1/08067 -7be adjusted. Using a dial indicator or other instrument, each of the replaceable cartridges 16 is adjusted so that the cutting edge 20 of the insert 18 held by the cartridge 16 is within two-ten thousandths of an inch of a common plane. The adjustment is accomplished by turning the adjusting screw 52 as required to move the cartridge in the direction needed to bring the cutting edge 20 to the common plane. If a forward adjustment is required, the adjusting screw 52 is turned in (or clockwise) to move the cutting edge forwardly towards the common plane. If a backward adjustment is required, the adjusting screw 52 is turned out (or counter-clockwise) to move the cutting edge 20 backwardly. In making a backward adjustment, it is generally advisable to move the cutting edge of the insert 18 beyond the common plane and then making a final forward adjustment to align the cutting edge 20 with the common plane. This procedure will prevent the tool cartridge 16 from slipping backward when the locking screw 62 is tightened. When the cutting edge 20 of the insert 18 is adjusted to the common plane, the locking screw 62 is tightened. There is no tendency of the cartridge 16 to slip during tightening of the locking screw 62 since the head 56 of the screw 52 also functions as a positive stop to prevent the cartridge 16 from slipping backward. The present invention may, of course, be carried out in other specific ways than those herein set forth without departing from the spirit and essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are intended to be embraced therein.
