Abstract
1295896 Boring tool holder REGIE NATIONALE DES USINES RENAULT 15 April 1970 [21 April 1969] 17898/70 Heading B3C A tool holder having an adjustable tool 0 comprises a body 1 formed as two elements, 1a which is connected to a spindle and 1b which carries the tool 0 and which is movable angularly about a hinge 1c against resilient forces. A push member 7 controls the adjustment of the tool 0 by acting on a lever 6 mounted in a hollow 1d of the body and engaging a pair of relatively radially closely spaced fulcrum points 8, 9 to produce a reduction ratio in the lever operation. In an alternative embodiment (Figs. 3, 4, not shown) the lever is formed with two blind passages (12), (13) which overlap to receive studs (18), (19) which provide the fulcrums. A wafer (14) of a plastics material is inserted between the ends of the studs to prevent friction sticking during adjustment. In a further embodiment (Fig. 5,-not shown) a second reducing ratio lever (36) is provided which is directly acted upon by the push member 7 and which is pivoted about trunnions (37) and carries a pin (39) which acts on the end of the primary lever (26). The trunnions (37) are carried on a rod (38) whose mounting includes a plastics ring (40) that provides temperature compensation for variations in the thickness of wafer (14) by moving the position of the trunnions (37).
