Special clamp for transmission piston die-casting part of rack

Abstract

The invention discloses a special clamp for a transmission piston die-casting part of a rack, which is characterized in that a main body of the special clamp is a clamp body, a butt-joint head matched with the shape of the transmission piston die-casting part of the rack is formed at one end of the clamp body, and the special clamp is provided with two pressing claws symmetrically arranged relative to the transmission piston die-casting part of the rack. The pressing claws are connected onto the butt-joint head through pins, one external supporting pin is in bolt connection in the butt-joint head through a symmetrical center of the two pressing claws in a penetrating mode, the external supporting pin is provided with a pin cap with taper, and the pin cap is contacted with claw tails of the two pressing claws. By means of the application of the technical scheme of the special clamp, the special clamp is simple in operation and has universal applicability to different dimensional changes of the piston die-casting part. By means of the application of the special clamp for the transmission piston die-casting part of the rack, the process difficulty is reduced, and the product quality of the workpiece processing and the processing efficiency are greatly improved. In addition, the special clamp for the transmission piston die-casting part of the rack meets needs of volume production of the piston die-casting parts.

Description

technical field [0001] The invention relates to a special fixture for industrial processing, in particular to a special fixture for firmly clamping and turning a rack drive piston die-casting, which belongs to the field of mechanical manufacturing. Background technique [0002] In the mechanical processing of general industrial parts, especially in turning processing, it is necessary to perform high-precision and high-stability clamping and positioning of the parts to be processed. In the prior art, when the rack drive piston die-casting workpiece is processed on the lathe, the outer circle clamping scheme is adopted twice. Due to the limitation of the product structure and size of the piston part, a three-jaw chuck is used to clamp the outer circle end of the piston part first. The outer circle is partially processed, and after the processing is completed, turn around and process the other end. Due to the small amount of clamping, easy deformation and low centering accurac...
