Shaft fork machining clamp

Abstract

The invention relates to the field of tools, and discloses a shaft fork machining clamp. The shaft fork machining clamp comprises a cable-stayed chuck and a positioning piece used for limiting the axis position of a second hole of a shaft fork, a clamping groove of the shaft fork is matched with an abutting plate in an embedded mode, and then the abutting plate slides on the contrary until the abutting plate extrudes the two opposite sides in the clamping groove; and the positioning shaft penetrates through the second hole of the shaft fork and an inserting hole in the abutting plate, a positioning shaft limits the movement of the axis of the shaft fork in the second hole, the abutting plate limits the movement of the shaft fork in the axis direction of the second hole, and finally a fixing claw moving relatively clamps and fixes the rotation of the shaft fork in the axis direction of the second hole, so that accurate positioning and fixing of the shaft fork are achieved, and the position precision of the first hole and the second hole in the shaft fork is improved.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a jig for processing a shaft fork. Background technique [0002] The shaft fork includes a main shaft and a fork that fixes one end of the main shaft. The bifurcation includes a set of symmetrically arranged bifurcated plates, and a snap-fit ​​slot is formed between the bifurcated plates, and a hole is opened in the main shaft along its axis 1, and a hole 2 is opened on the bifurcation plate, and the axis of the hole 2 is perpendicular to and intersects with the axis of the hole 1. [0003] In the prior art, the blank of the shaft fork is molded by die-casting. The blank includes the bifurcation body and the main shaft body, which are clamped on the main shaft body to process the inner surface of the clamping groove and hole 2. Both hole 1 and hole 2 of the blank need Finishing, but the requirements for the outer dimensions of the shaft fork are not high. The manufacturing standard of the...

Problems solved by technology

[0003] In the prior art, the blank of the shaft fork is molded by die-casting. The blank includes the bifurcation body and the main shaft body, which are clamped on the main shaft body to process the inner surface of the clamping groove and hole 2. Both hole 1 and hole 2 of the blank need Finishing, but the requirements for the outer dimensions of the shaft fork are not high. The manufacturing standard of the shaft fork requires that the axes between the first hole and the second hole are perpendicular to each other and intersect. Clamping the spindle rod for processing, because the outer surface of the blank has not been processed, the shape and size of the blank are quite different, resulting in the position accuracy of the processed hole 1 and hole 2 is not high, there are deficiencies to be improved
