Turning clamp of transmission hook blank

Abstract

The invention provides a turning clamp capable of clamping a transmission hook blank fast and conveniently. The turning clamp is provided with a base plate, a supporting base, a clamping component, two positioning blocks and a fastening screw. The base plate is connected with a main shaft of a lathe. The supporting base in an L shape and comprises a vertical connection portion connected with the base plate and a horizontal supporting portion located at one end of the vertical connection portion. The clamping component comprises a clamping base and a clamping piece. The clamping base comprises two vertical supporting blocks and a horizontal supporting block erected on the two vertical supporting blocks. The clamping base is connected with the horizontal supporting portion of the supporting base through the two vertical supporting blocks. The clamping piece comprises a pressing rod penetrating through the horizontal supporting block and stretching downwards and a pressing head formed at the lower end of the pressing rod. The two positioning blocks are formed on the horizontal supporting portion of the supporting base to abut against the two end faces of the hook formation portion of the transmission hook blank. The fastening screw penetrates through the vertical supporting blocks to abut against the rest side face of the hook formation portion of the transmission hook blank.

Description

technical field [0001] The invention relates to a turning fixture for a transmission hook blank. Background technique [0002] At present, sewing machines are widely used in the garment manufacturing industry, especially large-scale sewing machines used in factories, which are more widely used in the production enterprises that manufacture garments in batches. In such sewing machines, a small transmission hook is required. like figure 1 As shown, the transmission hook is formed by processing a transmission hook blank including a hook forming portion and a cylindrical hook handle connected to the hook forming portion. [0003] When processing such a transmission hook blank into a transmission hook, it is necessary to clamp the hook forming part to turn the hook handle, and then process the hook forming part to form the hook. However, since the overall shape of the transmission hook blank is irregular, it is not necessary to It is easy to clamp the drive hook blank for turni...
