Abstract

The invention discloses an automatic machining device for a curved needle crank of a sewing machine. The automatic machining device comprises a rotating disc workbench, wherein the rotating disc workbench is provided with an automatic feeding and discharging module, a small head end point hole module, a small head end drilling module, a small head end hole expanding module, a large head end reaming module, a first large head end drilling module, a second large head end drilling module, a taping module and a large head end sawing module in the circumferential direction. The automatic machining device integrates feeding and discharging, one station is formed, the structure is compact, the dimension of whole equipment can be reduced, and the working efficiency is higher. The invention further discloses an automatic machining method for the curved needle crank of the sewing machine.

Description

technical field [0001] The invention relates to a mechanized automatic processing device, in particular to an automatic processing device for a looper crank of a sewing machine. The invention also relates to an automatic processing method for a looper crank of a sewing machine. Background technique [0002] As the main structural part of the sewing machine, the looper crank of the sewing machine needs to bear a large force when working, and the working time is long, and the wear of the looper crank is relatively large. It is a link that the sewing machine often needs to be maintained. The demand is greater. [0003] The structure of the sewing machine looper crank 100 is as follows figure 1 As shown, it includes: the big end 100-1, the small end 100-2, the big end 100-1 and the small end 100-2 are fixedly connected as one through the connecting rod 100-3; the upper and lower ends of the big end 100-1 A large end through hole 100-4 and a threaded hole 100-5 are respective...
