Clamping device special for circular arc pen forklift groove

Abstract

The invention relates to a clamping device special for a circular arc pen forklift groove. The clamping device comprises a flange disc, a set of positioning components for installing workpieces are evenly distributed on the upper surface of the flange disc, and a pressing plate which is used for compressing the workpieces and positioned above each positioning component is installed at the position, arranged on the side edge of each positioning component, of the flange disc. The clamping device for the circular arc pen forklift groove is ingenious in design, reasonable in structure, convenient to use, high in practicability and long in service life, due to the fact that the device can complete machining of the multiple workpieces at a time, the machining time is greatly shortened, and the working efficiency and the machining precision are improved.

Description

Technical field [0001] The invention relates to the field of clamping tools, in particular to a special clamping device for arc pen forklift grooves. Background technique [0002] The surface of the arc pen fork of the sewing machine needs to be processed with grooves. At present, the groove is usually processed by a milling machine. Although this method is widely used, it still has the following defects: 1. Since only one workpiece can be processed per clamping, I want to process multiple The workpiece needs to be clamped many times to complete, so there are problems of slow processing speed and low efficiency in the processing process, which is not suitable for large-scale processing and production; 2. The processing accuracy is low, and the dimensional accuracy of the workpiece is difficult to guarantee. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a special clamping device for the arc pen fo...
