Abstract

The invention relates to a differential case drilling clamp which solves the technical problems that an existing clamp is complex in structure and cannot eliminate pressing fit clearance. The differential case drilling clamp is provided with a base, an expansion spring, an expansion cone, a compression spring A, a compression spring B and a cutter relieving hole, wherein the expansion spring is in an inner cone shape, the lower part of the expansion spring is provided with a sleeve with a through hole flange, and the upper part of the expansion spring is provided with an open groove; the expansion cone is sequentially provided with a screw rod, a small cylinder, an outer cone, a cylinder and a short cylinder from top to bottom; the outer cone of the expansion cone is matched with the inner cone of the expansion spring, and the outer circle of the expansion spring tightly presses a differential case by force generated by rotation of a compression nut on the screw rod arranged on the expansion cone so that the correct position of a machined hole can be ensured; and the short cylinder of the expansion cone is sleeved with the compression spring A. The differential case drilling clamp can be used in the field of differential case machining.

Description

technical field [0001] The invention relates to a jig, in particular to a drilling jig for a differential case. Background technique [0002] The differential of a car is a device that forms a speed difference. It has four holes for installing drive shafts and requires the two output shafts to always output the same torque. Accuracy requirements are more stringent. [0003] The Chinese invention patent application with the publication number CN109514289A discloses a differential case drilling jig, including thickened nuts, formwork, positioning discs, limit blocks, support blocks, diamond pins, opening pads, guide posts, templates , Press block, small end guide bush, middle guide bush, big end guide bush, bushing, pin shaft, pin spring, handle, bracket, positioning key, cover plate, transmission shaft, tapered roller bearing, flange, skeleton Oil seal, oil seal flange, rotary table body, rotary table, pressure plate, pressure plate gasket, compression spring, long screw, s...
