Description

Technical Field

[0001] The utility model relates to the field of jigs, and particularly to a jig structure for processing different thin-walled products on both the front and back sides. Background Art

[0002] The existing two types of electric drive housings are both thin-walled parts, and their front and side surfaces have multiple hole positions and mounting end faces that need to be milled flat. The conventional method is to process them through a machining center. Therefore, it is necessary to design two sets of jigs for clamping and positioning the two workpieces, and after one type of electric drive housing is processed, it is also necessary to replace the jig to process the other type of jig clamping. Therefore, the processing efficiency is not high, the jig cost is high, and the investment in machining equipment is even higher. In addition, the electric drive housing is a thin-walled part and is prone to deformation during the processing. The existing jig has poor support effect, so it is necessary to design a jig suitable for four-axis machine tool processing to improve the processing efficiency and reduce the processing cost.
