Problems solved by technology

Generally, the grip surface of cloth feeding tooth products is relatively narrow. When using the existing magnetic disk adsorption positioning method, the force point of the product is small during grinding, which causes the problem that the workpiece is easy to loose during processing, and the dimensional accuracy of the grip is difficult to guarantee.
Moreover, there are outstanding problems of low work efficiency and low workpiece yield

Abstract

The invention relates to a special fixing device for grinding a toothed handle of a feed dog. The special fixing device is characterized by comprising a base, a fixed frame, a locating column, a pressing plate frame, a pressing plate and a pressing plate set screw. The fixed frame is vertically and fixedly installed on the upper surface of the base, a clamping table is installed on the front face of the upper portion of the fixed frame, the locating column with the front end extending out of the vertical face of the clamping table is installed on the fixed frame in a penetrating mode, the set screw is arranged on the front face in the middle of the fixed frame, the rotatable pressing plate frame is installed at the bottom of the fixed frame through a pin shaft, the pressing plate is installed at the upper end of the pressing plate frame, the pressing plate corresponds to the clamping table on the fixed frame after the pressing plate frame rotates to be erected, and a clamping groove clamped with the set screw is formed in the middle of the pressing plate frame. The special fixing device for grinding the toothed handle of the feed dog is scientific and reasonable in structural design, and has the advantages that clamping is convenient, looseness of a workpiece in the grinding process is avoided, machining size is accurate, and work efficiency is high.

Description

technical field [0001] The invention belongs to a processing device for industrial sewing machine accessories, in particular to a special fixing device for grinding cloth feed dog handles. Background technique [0002] The feed dog is an essential part of an industrial sewing machine. Generally, the handle surface of the cloth feeding tooth product is narrow. When the existing magnetic disk adsorption positioning method is adopted, the force point of the product is small during grinding, which causes the problem that the workpiece is easy to loose during the processing process, and the dimensional accuracy of the handle is difficult to guarantee. Moreover, there are outstanding problems of low work efficiency and low workpiece yield. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a special fixing device for the grinding cloth feed dog handle which is stable and reliable, and can effecti...
