Abstract

The utility model discloses an electric engine stator processing jig, comprising a taper shank, an internal expanding round shell and an internal expanding core in correspondence with a stator internal wall. The taper shank is provided with a central cylinder in the center of the back end, in the center of which is provided with a holding screwed hole. An internal expanding round shell is arranged on the central hole in correspondence with the central cylinder in the center, fixed with the back end surface of the taper shank through a bolt. The round placket is positioned in the center of the internal expanding core, the side wall of which is provided with four through openings equally. The internal expanding core is a round plat core, in the center of which is provided with the step through opening, connected with the holding screwed hole through a holding bolt in the step through opening. In the end of the opening trough on the side wall of the internal expanding shell is equipped with a round expanding trough. The utility model has the advantages of simple structure, rapid fastening and improving work efficiency, for revolving in and out to fasten and loosen the stator.

Description

A kind of motor stator clamp for machining

Technical field

The utility model relates to the processing of motor stator, a kind of motor stator clamp for machining of specific design.

Background technology

Motor stator need be fixed in the rotating shaft adding on the lathe man-hour, traditional fixture structure complexity, and it is more loaded down with trivial details to add the operation in man-hour at the tightening stator, has influenced operating efficiency.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and a kind of fast motor stator clamp for machining of stator convenient fixing has improved operating efficiency.

To achieve these goals, the utility model adopts following technical scheme: a kind of motor stator clamp for machining, it is characterized in that: comprise taper shank, internal expanding round casing corresponding and internal expanding core body with stator inner wall, center, described taper shank rear end is provided with newel, the newel center is provided with the clamp screw pit, described internal expanding round casing center is provided with the centre bore corresponding with described newel, internal expanding round casing bottom is fixed on the taper shank rear end face by screw, internal expanding round casing front end face center is provided with the circular platform type opening, internal expanding round casing sidewall evenly has several grooves, described internal expanding core body is the circular platform type core body, internal expanding core body center is provided with step through-hole, and the internal expanding core body is connected in the described clamp screw pit by the holding screw that is located in the step through-hole.

Improved, described opening at its groove tail place of groove of internal expanding round casing sidewall is provided with the circular groove that expands, and helps the processing of groove and the spreading of shell wall.

Preferably, the described groove of opening at internal expanding round casing sidewall is 4.

The utility model adopts above-mentioned technical scheme, the taper shank of motor stator clamp for machining is installed in the lathe rotating shaft, when motor stator need fixedly add man-hour, as long as screw out holding screw, motor stator is enclosed within internal expanding round casing outer wall, precession holding screw then, the internal expanding core body advances, the expansion of tensioner housing outer wall, motor stator is firmly clamped, simple in structure, rapidly fixing, improved operating efficiency.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural representation;

Fig. 2 is an internal expanding round casing contour structures schematic diagram among Fig. 1.

The specific embodiment

As shown in Figure 1, be a kind of motor stator clamp for machining of the utility model, it comprises taper shank 1, internal expanding round casing 2 corresponding and internal expanding core body 3 with stator inner wall, center, described taper shank 1 rear end is provided with newel 11, newel 11 centers are provided with clamp screw pit 111, described internal expanding round casing 2 centers are provided with the centre bore 21 corresponding with described newel 11, internal expanding round casing 2 bottoms are fixed on taper shank 1 rear end face 13 by screw 4, internal expanding round casing 2 front end face centers are provided with circular platform type opening 22, internal expanding round casing 2 sidewalls evenly have 4 grooves 23, described internal expanding core body 3 is the circular platform type core body, internal expanding core body 3 centers are provided with step through-hole 31, and internal expanding core body 3 is connected in the described clamp screw pit 111 by the holding screw 5 that is located in the step through-hole 31.Be provided with the circular groove 24 that expands at the groove tail place of groove 23 for the ease of the processing of groove 23 and the spreading of shell wall.

The utility model is installed in the taper shank of motor stator clamp for machining in the lathe rotating shaft, when motor stator need fixedly add man-hour, as long as screw out holding screw, motor stator be enclosed within internal expanding round casing outer wall, precession holding screw then, the internal expanding core body advances, the expansion of tensioner housing outer wall firmly clamps motor stator, and is simple in structure, rapidly fixing, improved operating efficiency.
