Tool for grinding planes of outer circles of cylindrical pins

Abstract

The invention discloses a tool for grinding planes of outer circles of cylindrical pins. The tool comprises a base, wherein a group of inverted omega-shaped positioning grooves are formed in the top of the base; two or more bolt holes are formed in the base; a pressing block is arranged at one end of each inverted omega-shaped positioning groove; a rubber sheet and a supporting plate are arrangedat the other end of each inverted omega-shaped positioning groove; and bolts sequentially penetrate through the supporting plates, the rubber sheets, the bolt holes and the pressing blocks and then are screwed and fixed. According to the tool, the cylindrical pins can be clamped on the base in batches, so that the purpose of batch grinding is achieved, and the machining efficiency is improved; andmeanwhile, for parts with the same diameter and deviation in length size, the rubber sheets are arranged at one end of the base to eliminate the length error, so that the problem that the parts are not firmly clamped due to the length deviation is effectively solved.

Description

technical field [0001] The invention relates to a fixture, in particular to a tooling for cylindrical pin cylindrical grinding. Background technique [0002] The pin plays a pivotal role in the connection of mechanical parts. It is a fastener with a large production volume and many varieties, and it is also an irreplaceable fastener product. In the traditional machining industry, a surface grinder is generally used for the cylindrical grinding of pin parts, and the processing of the surface grinder is to fix the workpiece through a magnetic table. However, fixtures are required for the cylindrical grinding of small cylindrical parts. Grinding can only be carried out after clamping. [0003] However, the existing clamps are clamped by flat pliers, and only a few parts can be clamped at a time. When the product length is long, the clamping is not firm and the processing size is unstable. Due to the relatively large number of such parts, small diameter, strict dimensional tol...

Problems solved by technology

[0003] However, the existing fixtures are clamped by flat-nose pliers, and only a few parts can be clamped at a time. When the product length is long, the clamping is not firm and the processing size is unstable.

Due to the relatively large number of such parts, small diameter, strict dimensional tolerance and surface finish requirements, single-piece processing is time-consuming and labor-intensive, with high processing costs and low efficiency.
