An armature cutting device

Abstract

An armature head cutting equipment, including a frame, a workbench, a headstock and a tailstock, a hollow main shaft is installed horizontally in the headstock, the head of the main shaft is connected with the rotary drive mechanism, and the tail is provided with a clamping seat. The clamping seat is provided with an extruding inclined surface and an elastic collet; the top shaft connected with the elastic collet is slid horizontally in the main shaft, and the elastic collet is provided with a clamping groove, a notch and a shrinking slope; the tailstock is driven by a transverse drive mechanism Driven to slide on the workbench, the tailstock is provided with a tailstock tip; the outside between the tailstock and the headstock is provided with a tool seat driven by a vertical drive mechanism to slide on the workbench, and the tool seat is provided with There are circular cutters. The beneficial effects of the present invention are: the cutting head is flat, without deformation, low in cost, fast in clamping, short in processing time and extremely high in comprehensive processing efficiency.

Description

technical field [0001] The invention relates to an armature head cutting device. Background technique [0002] In the prior art, an armature is composed of an armature body and an enameled wire embedded in an armature slot of the armature body. During the production process, the enameled wire is first embedded in the armature slot with a margin, and then the excess enameled wire joint is cut off with a cutter. The disadvantages of this treatment method are: 1. Since the enameled wire is relatively soft, the cutter generally cuts the enameled wire joint in the form of extrusion, which tends to make the enameled wire tilt radially, resulting in incomplete cutting, and the enameled wire is at the commutator. It is easy to form a bow shape, which will affect the subsequent process, resulting in a large void rate during spot welding and reducing the welding strength. If the enameled wire is welded in the armature slot before cutting, although it can prevent deformation during c...

Problems solved by technology

The disadvantages of this treatment method are: 1. Since the enameled wire is relatively soft, the cutter generally cuts the enameled wire joint in the form of extrusion, which tends to make the enameled wire tilt radially, resulting in incomplete cutting, and the enameled wire is at the commutator. It is easy to form a bow shape, which affects the subsequent process, resulting in a large void rate during spot welding and reducing the welding strength

If the enameled wire is welded in the armature slot before cutting, although it can prevent deformation during cutting, it is a waste of solder, and it is not easy to cut off during cutting

2. When clamping the armature during the cutting process, generally put the sleeve on the armature jacket and put it between the two tops. The clamping is slow, the processing time is long, and it is easy to miss the sleeve, causing the machine tool to run dry. , the comprehensive processing efficiency is low
