Problems solved by technology

[0002] The shuttle bed is an important part of the rotary hook of the sewing machine. The structure and processing accuracy of the shuttle bed will determine the use status of the entire rotary hook. The shuttle bed is small in size, complex in structure, and has many processing procedures, so the processing accuracy is difficult to control.
[0003] The existing technology of Chinese Patent No. 201410173981.X is aimed at adding a process boss during the casting of the rotary hook bed. The main problem is to solve the problem of clamping during the processing, but only the hydraulic four-jaw clamp is used in the actual processing. Disk, can solve the above problems, increase the process boss, and it is easy to damage the tool during processing

Embodiment 1

[0076] The steps 1) to 5) are a process of rough machining, and the purpose is to prepare equipment for the finishing process in the later stage. Figure 5 In the process, the rotary hook bed is positioned through the auxiliary fixture 201. First, the auxiliary fixture 201 is fixed on the workbench of the equipment with a press plate, and the hook bed is placed on the auxiliary fixture 201. Then, the press plate is used to Combination 201-0 is compressed and fixed, and the lower surface of the connection seat is processed 17. Then, the bolt combination 201-01 is used to compress and fix, and the pressure plate combination 201-0 is removed. Finally, the large outer circle of the connection seat is processed 14, and the middle plane of the connection seat is 15 , The small outer circle 16 of the connecting seat, the side bevel B18 and the side bevel C19.

Abstract

The invention discloses a machining method for a rotating-shuttle shuttle race. The machining method includes a blank fabrication process, a machining process, a surface treatment process and a heat treatment process and includes the following steps of blank fabrication, preparation of a clamp device, rough machining, deburring, rough machining check, heat treatment, finish machining, finish machining check, surface treatment, polishing, cleaning, finished product final check and assembling. Technical problems generated during actual machining are solved; the machining steps are simpler and more reasonable and convenient; quick clamping is achieved and machining accuracy is guaranteed by means of tool clamps; therefore, the production efficiency is improved, and resource consumption is reduced.

Description

technical field [0001] The invention relates to a processing method of mechanical parts, in particular to a processing method of a rotary hook bed. Background technique [0002] The shuttle bed is an important part of the rotary hook of the sewing machine. The structure and processing accuracy of the shuttle bed will determine the use status of the entire rotary hook. The shuttle bed is small in size, complex in structure, and has many processing procedures, so the processing accuracy is difficult to control. [0003] The existing technology of Chinese Patent No. 201410173981.X is aimed at adding a process boss during the casting of the rotary hook bed. The main problem is to solve the problem of clamping during the processing, but only the hydraulic four-jaw clamp is used in the actual processing. The disc can solve the above problems, and the process boss is added, which is easy to damage the tool during processing. Contents of the invention [0004] A processing method...
