Abstract

The invention provides a tooling clamp for a crank arm, which belongs to the technical field of mechanical equipment, and specifically includes a first clamp assembly and a second clamp assembly, the first clamp assembly includes a first base, a first pressure plate, and the first base The upper surface of the upper surface is provided with a first groove, and the upper surface of the first pressure plate is provided with a second groove. The size is suitable, the second fixture includes a second base, a second pressure plate and a clamping part, a third groove is opened on the second base, a counterbore is opened at the bottom of the third groove, and a counterbore is opened on the second base. The two pressing plates are used to position the crank arm, and the second base is also provided with a first processing hole and a second processing hole. The crank arm is processed by the jig of the crank arm of the present invention, which has the advantages of simple process, less working procedure and high efficiency, and the appearance of the crank arm is more beautiful.

Description

technical field [0001] The invention relates to a processing tool, in particular to a tooling fixture for a crank arm. Background technique [0002] The crank arm is an interlocking drive on the switchgear, and it is used in large quantities. The existing processing method is as follows: the shape of the crank arm and the big hole of the crank arm are made by the casting mold, and the large hole of the crank arm is reserved for processing, and the large hole of the crank arm is processed by a CNC lathe, and then the hole is positioned to make the front end of the drilling mold. The positioning hole of the pin, and then the processed pin is welded to the crank arm by means of hole positioning. The above-mentioned processing method has high cost, complex process and long working hours, and the welding scars left in the welding process affect the appearance of the crank arm. Contents of the invention [0003] The problem to be solved by the present invention is to provide a...
