This invention concerns anchoring devices, more particularly anchoring devices adapted to support equipment such as machines, engines and transmissions for, for example, dynamometer testing, and other applications in which precision alignment of the equipment is required.
Mounting of equipment such as machine tools, engines and transmissions in dynamometer test stands requires precision positioning of the equipment on the base plate or other supporting surfaces Usually the anchoring devices provided for such purpose are laterally adjustable with respect to the base plate such that the alignment of equipment is carried out by means of such adjustment i e, as by a T-bolt and slot arrangement.
Another approach described in U S Patent No 2,940,297 provides the lateral adjustment by means of a slotted mounting hole, formed in an anchor ball, allowing for transverse adjustment to allow internal alignment with the equipment to be mounted These approaches involve a rather time consuming and painstaking movement of the engine or other equipment into position with a subsequent securing of the mounting means which is very time consuming and difficult, due to the mass of equipment involved.
Furthermore, upon tightening of the locking means in the adjusted position there is a tendency for the equipment to shift slightly, disturbing the alignment achieved in setting up the equipment.
In addition it is often desirable or necessary to carry out adjustments in more than one direction at a given support point which capability is not provided by the aforementioned conventional anchoring devices.
It is, therefore, an object of the present invention to provide a lateral adjustment mechanism suitable for use in conjunction with anchoring of, for example, engine transmission dynamometer set ups and similar situations in which the mechanism itself provides a means for adjusting the lateral position of the equipment mounted.
According to the present invention there is provided an anchoring arrangement for mounting a structure to a base surface comprising:
a body member; means for securing said body member to said base surface; an at least partially cylindrical slide member having means for mounting said structure thereto; lateral adjustment means for slidably mounting said slide member with respect to said body member for lateral adjustment with respect to said base surface, said means including a socket formed in said body member and adapted to slidably receive said slide member and engaging the cylindrical surface on said slide member, said body member further being formed with a slot extending into said socket to form opposed socket side walls; drive means included in said lateral adjustment means and adapted to reciprocate said slide member in said socket to thereby produce said lateral adjustment:
means for locking said slide member in said socket in any given adjusted position therein, said means including means for drawing said opposed socket side walls into locking engagement with said slide member, whereby said structure can be laterally adjusted with respect to said base surface and securely locked in a given position.
Further according to the present invention there is provided an anchoring arrangement having a lateral adjustment capability for supporting a structure with respect to a base surface comprising:
an anchor housing adapted to be secured to said base surface; a vertically extending shaft received within said anchor housing; ( 21) _I ( 31) CM ( 33) » ( 44) ( 51) ( 52) 1,592,100 means for adjusting the elevational position of said vertically extending shaft; lateral adjustment means carried by the upper end of said vertically extending shaft; said adjustment means including an at least partially cylindrical slide member, such slide member having mounting means for securing said supported structure thereto; means supporting said slide member for lateral movement along an axis parallel to the surface of said base surface, said supporting means including a body member having a socket formed therein and adapted to slidably receive said slide member for movement therein, said body member being formed with a slot extending into said socket along the length thereof to form opposed socket walls, said slide member being disposed in said socket with said mounting means accessible through said slot; drive means included in said lateral adjustment means and adapted to reciprocate said slide member in said socket to thereby produce said lateral adjustment; locking means for locking said slide member in any given adjusted position along said line of lateral movement, said locking means including means for drawing said socket walls formed by said slot into engagement with said slide member.
Embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings in which:Figure 1 is a perspective view of an anchoring device, incorporating a lateral adjustment mechanism according to the present invention; Figure 2 is a plan view of the lateral adjustment mechanism incorporated in the anchoring device depicted in Figure 1; Figure 3 is a view of Section 3-3 taken in Figure 2.
Figure 4 is a front elevational view of the lateral adjustment mechanism shown in Figures 1 to 3; Figure 5 is a view of Section 5-5 taken in Figure 2.
Figure 6 is a plan view of the slide element incorporated in the adjustment mechanism shown in Figures 1-5.
Figure 7 is a side elevational view of a pair of lateral adjustment mechanisms, adapted to provide a lateral adjustment of equipment mounted thereto: and Figure 8 is an elevational view of a pair of lateral adjustment mechanisms, stacked to provide an adjustment capability in two different directions at a single support point.
Referring to the drawings, particularly Figure 1, an anchoring device 10 is shown, adapted to be secured to the surface of a base plate 12 by means of a plurality of holddowns 14, engaging a flange 16, formed on an anchor housing 18 and having T-bolts, received within the hold-downs, including Tbolt 20, received within a series of crossing grooves 22, formed in the surface of the base plate 12 The anchoring device 10 also includes a screw shaft 24, received within the 70 anchor housing 18 and adapted to be adjusted in elevation by means of a threaded ring 26 and secured in a given adjustment position by a pair of bolts 28, drawing together opposite halves of a split portion 30 of the housing 18 75 so as to securely engage the lower end of the threaded screw shaft 24 A pair of thrust bearings 25 and 27 are included in a recess in the lower part of the threaded ring 26 and a recess in the upper portion of the anchor 80 housing 18 to allow adjustment of the threaded ring 26 under load The anchoring mechanism 10 is adapted for lateral adjustment by virtue of a slotted mounting hole 34 with a T-bolt 36, passing there through and 85 into engagement with a groove 22, formed in the base 12.
Secured to the upper end of the threaded screw shaft 24 is a lateral adjustment mechanism 32 This mechansim is depicted in detail 90 in Figure 2 to 6 As will be described hereinafter in more detail, the lateral adjustment mechanism 32 allows for one lateral adjustment, the screw shaft 24 providing for vertical adjustment and the slot 34-bolt 36 arrange 95 ment providing for a second lateral adjustment such that X, Y and Z position adjustment of equipment mounted to the lateral adjustment mechanism 32, can be carried out.
The lateral adjustment mechanism 32 100 includes a body member 38, adapted to be fastened to the threaded screw shaft 24 by means of a capscrew 40, passing through a portion of the body member 38 and threadably engaging a threaded bore 44, formed in 105 the top of the screw shaft 24 The body member 38 is formed with a socket opening 46 of a partially cylindrical configuration, being open at the top so as to form a slot to allow the upper portion of a slide member 48 110 to extend, the slide member 48 being slidably disposed in the socket opening 46 The slide member 48 is formed with partially cylindrical surfaces, socket 46 being formed with corresponding cylindrical surfaces, with re 115 lieved areas 50 and 52 formed intermediate the top and bottom edges A pair of lock bolts 54 and 56 are provided, adapted to pass through oversized openings 55 and 57 formed in the slide 48, and are received in threaded 120 holes and formed in bosses 62 and 64 so that upon advancing of the lock bolts 54 and 56, the sidewalls of the socket 46 are drawn together to securely engage the cylindrical surfaces of the slide 48 The nature of this 125 engagement minimizes any movement of the slide by virtue of its reaction against the socket sidewall so as to eliminate any tendency for the equipment supported to be shifted upon locking engagement therewith 130 1,592,100 The upper surface of the slide 48 is formed with a flat surface 64 A into which is formed a tapped hole 66 which provides access for installation of the capscrew 40 and also provides means for securing the equipment to be mounted to the slide 48.
The slide 48 is adapted to be reciprocated within the socket 46 for the limited movement allowed by the oversized holes 55 and 57 by virtue of a driving engagement with drive means comprised of a capscrew 68 carried by the body member 38 with the head 70 of the capscrew being retained in a recess 72 and a threaded body 74 engaging a threaded hole 76, formed in the end surface of the slide 48, disposed adjacent thereto A cover 77 is provided to prevent the entrance of dirt etc, into the recess 72.
In use the machine, engine or transmission would be mounted at an approximate location to a plurality of the anchoring devices 10 by bolting the engine mounts or adapters therefor to the threaded hole 66 in the slide 48 The locking bolts 54 and 56 being loosened, the capscrew 68 is rotated to cause the slide 48 to be adjusted in its lateral position so as to allow positioning of the equipment along the direction defined by the longitudinal axis of the slide 48 Upon properly aligning the equipment, the lock bolts 54 and 56 would then be tightened to secure equipment in the adjusted position.
In the context of engine transmission dynamometer testing lateral adjustment of the equipment would normally take place with oppositely disposed pairs of lateral adjustment mechanisms 32 as shown in Figure 7.
In this instance the equipment 78 would be adjusted by virtue of operation of one of the lateral adjustment mechanisms with the capscrew 68 being omitted in the oppositely disposed one of such pair of lateral adjustment mechanisms 32 with both sets of locking bolts 56 and 54 being tightened to securely position the equipment 78 in the adjusted position.
In some instances it may be advantageous to provide lateral adjustments in more than one direction at a given support point In this instance the lateral adjustment mechanisms 32 described may be stacked as shown in Figure 8 with the capscrew 40 of the upper lateral adjustment mechanism 32 which is normally disposed to engage the upper surface of the threaded screw shaft 24, extending into the mounting hole 66, formed in the slide member 48 of the lower lateral adjustment mechanism 32 as shown in Figure 8.
The orientation of the mechanisms would -60 be in transverse directions to each other but it should be understood that the relative orientation of the longitudinal axes of the respective slide members 48 could be at any desired angle.
It can be seen that this arrangement provides a very rapid and precisely controllable adjustment, since the adjustment means constitutes a driving mechanism to position the equipment with respect to the support anchors 10 in lateral directions In addition it 70 can be seen that the locking means provides very rigid securement in any given adjustment position of the equipment 78 without any great tendency for shifting of the relative adjusted position upon engagement there 75 with.
It should also be appreciated that the lateral adjustment mechanisms could be directly mounted to a base plate or other supporting structure if elevational adjust 80 ments were not required or provided by some other means.
