Push-in type positioning fixture for driving motor housing of pure electric vehicle

Abstract

The invention relates to a push-in type positioning fixture for a driving motor housing of a pure electric vehicle. The push-in type positioning fixture comprises a bottom plate, a translation panel and a back vertical plate, wherein two longitudinal slide rails are mounted in the middle of the upper end surface of the bottom plate side by side, the translation panel sliding back and forth is mounted on the longitudinal slide rail, the back vertical plate is vertically mounted at the back part of the bottom plate, an expanding positioning pin is mounted in the central position of the front side of the back vertical plate, three positioning head seats surrounding the expanding positioning pin are arranged on the front side of the back vertical plate, elongated positioning blocks are transversely mounted at front and back parts of the upper end surface of the translation panel, and a front support and a back support are mounted at front and back ends of the upper end surface of the translation panel respectively. The push-in type positioning fixture has the characteristics of simplifying positioning operation of the motor housing, improving the finish machining efficiency, facilitating detection process and finish machining process structures and improving the product production efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of finishing jigs, in particular to a push-in positioning jig used for a drive motor housing of a pure electric vehicle. Background technique [0002] The motor shell is generally made of large die-casting parts, and it is very difficult to clamp the fixture. Because the shell shape generally adopts a cylindrical structure, there are multiple irregular connecting frames arranged on the outer ring of the shell. If you choose to place the motor shell vertically, During machine tool processing, the hole of the irregular connecting frame is on the side, which is not conducive to the synchronous processing of the CNC machine tool. At the same time, there will be some interference between the shell and the processing fixture, which is not conducive to the movement of the tool and cause production accidents. In order to solve this problem, it is necessary to Design a new positioning fixture. Contents of the inven...
