Shell key groove cutting machining device

Abstract

The invention provides a shell key groove cutting machining device. The device comprises a positioning mandrel, a tool apron, a tool bar and a blade, wherein one end of the positioning mandrel is used for being arranged on a planer spindle in a clamped mode, the other end of the positioning mandrel is used for being fixedly connected with a workpiece by means of a plug pin penetrating through the positioning mandrel, the tool apron is used for being arranged on a planer tool rest in a clamped mode, one end of the tool bar is inserted into the tool apron, the other end of the tool bar extends out of the tool apron, the blade is fixed to the outer end face of the tool bar by means of screws, two cutting edges are arranged on the upper side and the lower side of the blade, two cutting edge walls are arranged on the left side and the right side of the blade, and the two cutting edge walls are arranged in a mirror image opposite mode with respect to a connecting line between midpoints of the two cutting edges. By the adoption of the technical scheme of the device, the whole structure of the blade is evenly distributed, back chipping can be conveniently conducted on the root of a key groove in the planing process, the cutting quality of the shell key groove is improved, the positioning mandrel is adopted for clamping the workpiece, the center axis of the workpiece can be conveniently and correctly aligned, and a foundation is laid for improving the machining quality.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to a housing keyway cutting and processing device. Background technique [0002] At present, the existing motor products generally include a housing, and the existing motor housing is generally provided with a plurality of keyways, and the cutting of these keyways is relatively difficult. In the prior art, two methods are mainly used for processing and forming , one adopts the overall extrusion molding process, so that the shell and the corresponding keyway features are extruded by extruding the material. In this method, the raw material is generally in the form of powder particles, and the extrusion molding process requires environmental temperature and pressure conditions. , Strictly control the molding time, a little carelessness will lead to the scrapping of the product and affect the quality of the finished product. Another method is to use a planer to cut and proces...

[0002] At present, the existing motor products generally include a housing, and the existing motor housing is generally provided with a plurality of keyways, and the cutting of these keyways is relatively difficult. In the prior art, two methods are mainly used for processing and forming , one adopts the overall extrusion molding process, so that the shell and the corresponding keyway features are extruded by extruding the material. In this method, the raw material is generally in the form of powder particles, and the extrusion molding process requires environmental temperature and pressure conditions. , Strictly control the molding time, a little carelessness will lead to the scrapping of the product and affect the quality of the finished product. Another method is to use a planer to cut and process, and cut part of the material through the reciprocating movement of the planer clamped on the planer. However, this The root of the keyway processed by this method is not easy to clean the root, and the molding quality is also poor
