Description

Technical Field

[0001] The invention relates to the field of processing and manufacturing automobile parts, and in particular to a lathe jig for a disc brake control rod. Background Art

[0002] As part of an automotive component, the disc brake lever's main function is to rotate a semicircle around an eccentric axis by pushing a long handle with another push rod. The deviation between the semicircle and the eccentric axis is the control distance of the brake disc. Therefore, the shape of this product mainly requires two sets of semi-cylinders and a long rod to connect the two semi-cylinders. In common production and processing, the two sets of semi-circles are mainly milled separately on a machining center. However, the machining process using interpolation tools in the machining center is time-consuming and cost-effective.

[0003] Without affecting the processing quality, turning can reduce the processing time and reduce the processing cost, but the interference positioning between the long handle of the controller and the semi-cylinder is serious.

[0004] Therefore, it is necessary to provide a lathe jig for a disc brake control rod to solve the above problems. Summary of the Invention
