Process for quickly machining sewing machine flat plates

Abstract

The invention discloses a process for quickly machining sewing machine flat plates. The process comprises the following steps of finishing milling of the peripheries of the flat plates through a vertical machining center; quickly clamping the plurality of flat plates through a double-side hydraulic clamp on a vertical machining machine tool to finish milling and punching of the front surfaces andback surfaces of the flat plates and milling of inner cavity walls of the flat plates; quickly positioning and clamping the plurality of flat plates through a multi-layer hydraulic clamp on a horizontal machining machine tool so as to finish the machining of edge holes of the flat plates and lower shaft holes in the middle; and carrying out four working procedures including fine machining on mainholes of the flat plates. By means of the process, the machining of the flat plates can be completed by just the four working procedures, quick positioning and quick clamping are realized, the efficacy and the yield per unit time are improved, and the machining precision is ensured.

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
