Description

Technical Field

[0001] The present invention relates to the field of machining, and particularly to a new type of motor stator fixture. Background Art

[0002] The motor stator is an important part of motors such as generators and starters. The stator is an important part of the motor. The stator consists of three parts: a stator core, a stator winding, and a frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current.

[0003] At present, most motor stators adopt a forming operation of assembling and then welding. However, the existing assembling and welding operations still use manual welding operations, and during the welding process, the assembled motor stator to be welded cannot be well limited and locked, which is not convenient for actual welding operations, and thus the production efficiency cannot be further improved. For this reason, those skilled in the art urgently need to develop an auxiliary fixture for assembling and welding motor stators.

[0004] Generally, a split stator of a servo motor needs to be assembled using a device, and a very high requirement is imposed on the true roundness of the overall stator during assembly.

[0005] The existing technology has the problem that when assembling a split stator of a servo motor, it is difficult to maintain the roundness of the motor stator. As a result, during the motor assembly process, due to the insufficient roundness of the motor stator, the motor stator and the motor housing are prone to misalignment or deformation during assembly, which in turn leads to an asymmetric rotating magnetic field of the motor, resulting in a decline in motor performance. Summary of the Invention

[0006] The purpose of the present invention is to solve the above problems and design a new type of motor stator fixture.

[0007] To achieve the above purpose, the technical solution of the present invention is as follows: A new type of motor stator fixture includes an integral telescopic rod. The integral telescopic rod includes a front rod and a rear rod. Both the front rod and the rear rod are cylindrical. A first limiting plate is provided between the front rod and the rear rod. One end of the front rod is fixedly connected with a top extension component. The connection mode between the top extension component and the front rod is a card slot type fixed connection. A convex inclined slide rail is provided on the rectangular cross-section of the top extension component. The upper end of the inclined slide rail is connected to a straight slide rail. A sliding and fixing structure is clamped on the inclined slide rail.

[0008] As a further description of the present invention, a clamping mechanism is sleeved on the outer sides of the front section of the front rod and the top extension component, and a second limiting plate is wrapped and connected around the periphery of the clamping mechanism.

[0009] As a further description of the present invention, a first bolt is fixed on the first limiting plate and penetrates through the first limiting plate and the integral telescopic rod, and a second bolt of the second limiting plate and the clamping mechanism is fixedly inserted on the second limiting plate.

[0010] As a further description of the present invention, a spring is arranged between the first limiting plate and the second limiting plate, first clamping holes are arranged on both sides of the first limiting plate, second clamping holes are arranged on both sides of the second limiting plate, and a guide shaft penetrates through and connects the first clamping holes and the second clamping holes.

[0011] As a further description of the present invention, the clamping mechanism is integrally in a hollow cylindrical shape, and the clamping mechanism includes a limiting clamping groove arranged at the bottom of the clamping mechanism corresponding to the inner diameter of the brush holder, and the limiting clamping grooves are arranged in a circumferential arrangement.

[0012] As a further description of the present invention, a limiting sliding groove is arranged at the end of the clamping mechanism, and the sliding and pushing fixing structure is inserted into the limiting sliding groove.

[0013] As a further description of the present invention, the sliding and pushing fixing structure includes a sliding plate clamped on an inclined sliding rail, an L-shaped pushing plate is arranged at one end of the sliding plate, and a wire pushing groove is arranged at the end of the L-shaped pushing plate.

[0014] As a further description of the present invention, a clamping groove with a convex cross-section is arranged at the end of the rear rod of the integral telescopic rod.

[0015] The beneficial effects are as follows: the integral telescopic rod pushes out the top extension part, and the inclined sliding rail fixed on the top extension part is also pushed forward. A limiting sliding groove is arranged at the end of the clamping mechanism on the periphery of the top extension part, and this sliding groove can be used to fix the slot opening of the motor stator, playing a very good positioning role. The sliding and pushing fixing structure is inserted into the limiting sliding groove. Under the guiding action of the inclined sliding rail, the integral telescopic rod extends downward, so that the sliding and pushing fixing structure clamped on the inclined sliding rail slides to the lower end of the clamping mechanism, ensuring that the sliding and pushing fixing structure clamped on the inclined sliding rail moves along the inclined horizontal direction of the inclined sliding rail. The sliding plate on the sliding and pushing fixing structure will synchronously push the L-shaped pushing plate forward to press the wire of the motor. After pressing and fixing this station, it returns to the original position through the spring, and then presses and fixes the next station, and can very well and accurately fix the hole position of the upper wire of the motor through this fixture.

Specific implementation mode

[0020] The present invention will be specifically described below in conjunction with the accompanying drawings. As shown in Figure 1 -3, a new type of motor stator fixture includes an integrated telescopic rod 1. The integrated telescopic rod 1 includes a front rod and a rear rod. Both the front rod and the rear rod are cylindrical. A first limit plate 2 is arranged between the front rod and the rear rod. One end of the front rod is fixedly connected with a top extension component 3. The connection mode between the top extension component 3 and the front rod is a clamping groove type fixed connection. A convex inclined slide rail 4 is arranged on the rectangular cross-section of the top extension component 3. The upper end of the inclined slide rail 4 is connected with a straight slide rail 5. A sliding and fixing structure 6 is clamped on the inclined slide rail 4. The overall effect is that the integrated telescopic rod 1 pushes out the top extension component 3, and the inclined slide rail 4 fixed on the top extension component 3 is also pushed forward together. Through the guiding action of the inclined slide rail 4, it is ensured that the sliding and fixing structure 6 clamped on the inclined slide rail 4 moves along the inclined horizontal direction of the inclined slide rail 4.

[0021] A clamping mechanism 7 is sleeved outside the front section of the front rod and the top extension component 3. The periphery of the clamping mechanism 7 is wrapped and connected with a second limit plate. A first bolt 9 that penetrates the first limit plate 2 and the integrated telescopic rod 1 is fixed on the first limit plate 2. A second bolt 10 that penetrates the second limit plate 8 and the clamping mechanism 7 is fixedly inserted on the second limit plate 8. The second limit plate 8 is fixedly installed in the peripheral area of the clamping mechanism 7 through the second bolt 10. The integrated telescopic rod 1 extends downward, so that the sliding and fixing structure 6 clamped on the inclined slide rail 4 slides down to the lower end of the clamping mechanism 7.

[0022] As a further description of the present invention, a spring 11 is arranged between the first limit plate 2 and the second limit plate 8. After being pressed down, the spring 11 can play a role in returning to the original position. First clamping holes 12 are arranged on both sides of the first limit plate 2. Second clamping holes 13 are arranged on both sides of the second limit plate 8. The first clamping holes 12 and the second clamping holes 13 are connected through a guiding shaft 14.

[0023] The snap - connection mechanism 7 is integrally in the shape of a hollow cylinder. The snap - connection mechanism 7 includes a limit card slot 15 provided at the bottom of the snap - connection mechanism 7 and corresponding to the inner - ring size of the brush holder. The limit card slots 15 are arranged in a circular pattern. A limit sliding groove 16 is provided at the end of the snap - connection mechanism 7. This sliding groove can be used to fix the notch of the motor stator, playing a very good positioning role. The sliding - push fixing structure 6 is inserted into the limit sliding groove 16.

[0024] The sliding - push fixing structure 6 includes a sliding plate 17 clamped on the inclined slide rail 4. One end of the sliding plate 17 is provided with an L - shaped push plate. A wire - pushing groove is provided at the end of the L - shaped push plate. The wire - pushing groove is used to clamp and fix the wires on the motor.

[0025] At the end of the rear rod of the integral telescopic rod 1, a clamping groove 18 with a convex - shaped cross - section is provided. The integral telescopic rod 1 is fixed through the clamping groove 18, and the integral telescopic rod 1 is driven by other components to press down.

[0026] Working principle: The integral telescopic rod 1 pushes out the top - extending component 3. The inclined slide rail 4 fixed on the top - extending component 3 is also pushed forward together. A limit sliding groove 16 is provided at the end of the snap - connection mechanism 7 around the top - extending component 3. This sliding groove can be used to fix the notch of the motor stator, playing a very good positioning role. The sliding - push fixing structure 6 is inserted into the limit sliding groove 16. Under the guiding action of the inclined slide rail 4, the integral telescopic rod 1 pushes downwards, causing the sliding - push fixing structure 6 clamped on the inclined slide rail 4 to slide down to the lower end of the snap - connection mechanism 7, ensuring that the sliding - push fixing structure 6 clamped on the inclined slide rail 4 moves along the inclined horizontal direction of the inclined slide rail 4. The L - shaped push plate on the sliding - push fixing structure 6 will synchronously push the wire - pushing groove forward to press the wires of the motor tightly. After pressing and fixing this station, it returns to the original position through the spring 11, and then presses and fixes the next station.
