Universal joint cage window cutting jig

Abstract

The invention relates to a cutting clamp for a universal joint retainer window. The cutting clamp comprises a fixed clamp and a movable clamp, wherein the fixed clamp is formed by connecting two concentric round plates through a screw, the circle center of one round plate is fixedly arranged on a rotating shaft of a servo motor, a screw hole is formed in the circle center of the other round plate, a through hole is formed in the circle center of the movable clamp, and a bolt penetrates through the through hole of the movable clamp and is matched with the screw hole of the fixed clamp through a screw thread; an adjustable radial compaction device for radially clamping and positioning a retainer is arranged between the two round plates of the fixed clamp, and the retainer rotates at a set angle by the servo motor, so that cutting of the circumferential retainer window is implemented. The cutting clamp is suitable for clamps of retainers of all kinds of specifications, and has the advantages of simplicity and convenience in clamping, no clamp abrasion, avoidance of maintenance, high processing efficiency, low processing cost, good window processing precision and the like.

Description

technical field [0001] The invention relates to a processing tool fixture for auto parts, in particular to a universal joint cage window cutting tool. Background technique [0002] The cage is an important part of the ball cage type universal joint. The universal joint cage is composed of inner and outer spherical surfaces and two planes. Six windows are uniformly made on the circumference of the spherical surface in the middle of the two planes. At present, the processing of the universal joint cage window is generally formed by punching with a traditional manual punching machine. Each hole needs to be stamped twice and ground once. The first time is to punch the window forming hole, and the second time is Punch the window size hole and then grind it. Its main disadvantages are: cages of different specifications require different molds, the number of molds is huge, the molds are worn during use, resulting in dimensional deviations, frequent adjustments and maintenance are ...

AI Technical Summary

Problems solved by technology

Its main disadvantages are: cages of different specifications require different molds, the number of molds is huge, the molds are worn during use, resulting in dimensional deviations, frequent adjustments and maintenance are required, high processing costs, low production efficiency, and affect processing accuracy; window punching and cutting The parallelism of the seam is poor, the verticality between the slit and the surface is poor, the dimensional accuracy of the incision is poor, and the processing technology is complicated
