A technology for rapid processing of sewing machine flat plate

Abstract

The invention discloses a process for rapidly processing a flat plate of a sewing machine. A vertical machining center is used to complete the milling process around the flat plate; a double-sided hydraulic clamp on the vertical processing machine tool quickly clamps a plurality of flat plates to complete the front and back sides of the flat plate. Surface milling, drilling, and milling of the inner cavity wall of the flat plate; on the horizontal processing machine tool, multiple flat plates are quickly positioned and clamped by multi-layer hydraulic clamps to complete the side holes and the middle of the flat plate. Machining of the lower shaft hole; four processes including finishing the main hole of the plate are realized. Through the method of the invention, only four processes are required to complete the processing of the flat plate, and fast positioning and fast clamping are realized, thereby improving the efficiency, increasing the output per unit time, and ensuring the processing accuracy at the same time.

Description

technical field [0001] The invention relates to the field of processing equipment for sewing machine parts, in particular to a process for quickly processing flat plates of sewing machines. Background technique [0002] In the prior art, the processing of the flat plate of the sewing machine is done through 3 horizontal machining centers and 6 vertical machining centers to complete all the processing of the flat plate including face milling, rough machining of all holes on the flat plate, and finishing of the lower shaft hole. , and its processing procedures are not less than 9. This not only affects the work efficiency and reduces the output per unit time, but also when the sewing machine plate is processed, it is mainly clamped by the positioning fixture. When the sewing machine plate is clamped, it is necessary to find the positioning pin on the base plate, and then insert The positioning pin hole of the plate is facing the positioning pin on the foundation plate, and th...

This not only affects the work efficiency and reduces the output per unit time, but also when the sewing machine plate is processed, it is mainly clamped by the positioning fixture. When the sewing machine plate is clamped, it is necessary to find the positioning pin on the base plate, and then insert The positioning pin hole of the plate is facing the positioning pin on the foundation plate, and the positioning pin is inserted into the positioning hole of the plate to realize the positioning of the plate. The positioning is very troublesome; and after the positioning is completed, it needs to be pressed by the pressing mechanism. Now The pressing mechanism of the machine mainly uses bolts to compress the pressing block. The way of pressing the pressing block through the bolts needs to manually twist the bolts to make the pressing block top the workpiece to be pressed, so the efficiency of clamping is relatively slow. During the processing Due to the vibration of the workpiece, the bolts loosen during the vibration, resulting in the workpiece not being compressed during the machining process and jumping, which affects the machining accuracy of the workpiece
