Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Such as figure 1 , figure 2 , image 3 , Figure 4 The shown AC traction motor rotor turning device mainly includes a base 1, a first screw transmission mechanism 4, a left clamping part 7, a right clamping part 8, a second screw transmission mechanism 14 and a rotor supporting frame 15. The left clamping part 7 and the left bearing seat 6 form a relatively rotating active connection structure, and the right clamping part 8 stands opposite to the left clamping part 7 and forms a relative rotating active connection with the right bearing seat 9 structure. The first lead screw transmiss...

Abstract

The invention provides an overturning device for an alternating-current traction motor rotor. The overturning device comprises a second lead screw transmission mechanism (14), a left clamping piece (7) and a right clamping piece (8), wherein the left clamping piece (7) and the right clamping piece are erected oppositely. A relatively-rotatable movable connecting structure is formed between the left clamping piece (7) and a left bearing seat (6). A relatively-rotatable movable connecting structure is formed between the right clamping piece (8) and a right bearing seat (9). A sliding seat in the second lead screw transmission mechanism (14) is fixedly connected with the right bearing seat (9) and a lead screw is driven by a motor. The right clamping piece (8) is driven by the motor and does reciprocating rectilinear motion relative to the left clamping piece (7) and is driven by the motor and does rotating motion relative to the right bearing seat (9). By the adoption of the overturning device, the motor rotor overturning working time can be shortened, the motor rotor overturning working efficiency is improved, the labor intensity of working staff is lowered effectively, and the overturning device has the remarkable beneficial effects of being easy to operate, convenient to use, safe, reliable and the like.

Description

technical field [0001] The invention relates to the technical field of manufacture of an AC traction motor rotor, in particular to an AC traction motor rotor turning device for welding an AC traction motor rotor end ring guide bar. Background technique [0002] In the manufacturing process of the rotor of the AC traction motor, it is necessary to carry out the welding operation of the guide bar of the end ring of the rotor of the AC traction motor. In the existing welding operation of the end ring guide bar of the AC traction motor rotor, one end is usually welded at high temperature first, and then the operator lifts the motor rotor on the rubber pad through the crane, and after turning the motor rotor 180° , and then carry out the second end welding operation. In the process of hoisting and turning the motor rotor, it is easy to cause bumps on the motor rotor product, which brings hidden dangers to the quality of the motor rotor. In addition, the existing operation method...
