[0002] When assembling the motor in the gearbox of the rear cover opening mechanism of an automobile, it is necessary to sleeved the shaft hole of the magnetic ring on the output shaft of the motor, and press the magnetic ring to the specified position of the motor shaft by means of pressing. Since the motor shaft and the magnetic ring are in interference fit, the assembly process has high requirements for pressure and displacement.

[0003] In the prior art, the motor is first installed and fixed in the card slot of the motor, and then the magnetic ring is placed in the upper die cavity. Next, a hand press is used to press down to press the magnetic ring in place. During this period, both the magnetic ring and the motor rely on manual handling, resulting in high labor intensity and low efficiency, and it is not suitable for assembly line production.

[0004] Therefore, in view of this, research and improvement are carried out on the deficiencies of the existing structure, and a magnetic ring pressing tooling for motors is proposed. Content of the Utility Model

[0009] Further, a limit pressing assembly is fixed on the right side of the motor conveyor belt. The limit pressing assembly includes a right side plate, a cylinder two and an H-shaped plate. The cylinder two is bolted and fixed on the outside of the right side plate, and the output end of the cylinder two is fixedly connected with the H-shaped plate.

[0010] Furthermore, the limiting and press-fitting assembly further includes limiting rollers. Limiting rollers are provided at the bottoms of both ends of the H-shaped plate, and the gap between the opposite limiting rollers is matched with the size of the motor body.

[0011] Furthermore, the limiting and press-fitting assembly further includes a bracket and a third cylinder. The bracket is fixedly bolted to the outside of the right side plate, and the third cylinder is fixedly mounted on the top of the end of the bracket.

The end opening of the limit groove 204 at the middle end of the top of the end plate 202 is located directly above the motor shaft. The magnetic ring materials are stacked up and down inside the magnetic ring cartridge 208. Under the action of gravity, the magnetic ring materials fall into the limit groove 204 through the bottom opening of the magnetic ring cartridge 208 and are pushed by the crescent pusher plate 206. The photoelectric switch 203 inside the end plate 202 corresponds to the motor body part, which can control the motor rotor on the motor conveyor belt 1 to stay at a specified station and wait for assembly with the magnetic ring materials. The magnetic ring materials are stacked up and down inside the magnetic ring cartridge 208. During use, under the action of gravity, the magnetic ring materials fall into the limit groove 204 through the bottom opening of the magnetic ring cartridge 208, and are further pushed by the crescent pusher plate 206 driven by the cylinder 1 205. The end opening of the limit groove 204 at the middle end of the top of the end plate 202 of the present application is located directly above the motor shaft, so that the magnetic ring materials falling from the end of the limit groove 204 under the push of the crescent pusher plate 206 are sleeved on the motor rotor, realizing the positioning and conveying of the magnetic ring materials in the present application and improving the automatic assembly efficiency;

[0022] As Figures 1 to 3As shown in the figure, a limit pressing assembly 3 is fixed to the right side of the motor conveyor belt 1.

The limit rollers 304 are provided at the bottoms of both ends of the H-shaped plate 303, and the gap between the opposite limit rollers 304 is matched with the size of the motor body. When it is sensed that the motor rotor stops at a specified position, the second cylinder 302 drives the limit rollers 304 at both ends of the H-shaped plate 303 to descend, so as to limit the motor rotor at the assembly station and ensure the assembly accuracy. The limit pressing assembly 3 further includes a bracket 305 and a third cylinder 306. The bracket 305 is bolted to the outside of the right side plate 301, and the third cylinder 306 is fixedly installed at the top of the end of the bracket 305.

A pressure sensor is provided between the pressing head 308 and the guiding sliding plate 307. The third cylinder 306 at the end of the bracket 305 drives the guiding sliding plate 307 to move downward. The guiding sliding plate 307 is slidably matched with the end of the bracket 305 through a guide rod to ensure the accuracy of the downward movement stroke. The pressure sensor at the connection between the pressing head 308 and the guiding sliding plate 307 ensures the appropriate pressing force. By accurately controlling the pressure and displacement, the interference fit accuracy between the magnetic ring material and the motor rotor is ensured.

[0023] Working principle: When using this motor magnetic ring pressing tooling, the photoelectric switch 203 inside the end plate 202 corresponds to the motor body part, which can control the motor rotor on the motor conveyor belt 1 to stop at the specified station and wait for the assembly with the magnetic ring material. The magnetic ring material is stacked up and down inside the magnetic ring cartridge 208. When in use, under the action of gravity, the magnetic ring material falls into the limit groove 204 through the opening at the bottom end of the magnetic ring cartridge 208, and is further pushed by the crescent-shaped push plate 206 driven by the first cylinder 205. The opening at the end of the limit groove 204 in the middle of the top of the end plate 202 of the present application is located directly above the motor rotating shaft, so that the magnetic ring material falling from the end of the limit groove 204 under the push of the crescent-shaped push plate 206 is sleeved on the motor rotor, realizing the positioning and conveying of the magnetic ring material of the present application and improving the automation assembly efficiency. When it is sensed that the motor rotor stops at a specified position, the second cylinder 302 drives the limit rollers 304 at both ends of the H-shaped plate 303 to descend, so as to limit the motor rotor at the assembly station and ensure the assembly accuracy. After that, the third cylinder 306 at the end of the bracket 305 drives the guiding sliding plate 307 to move downward. The guiding sliding plate 307 is slidably matched with the end of the bracket 305 through a guide rod to ensure the accuracy of the downward movement stroke. The pressure sensor at the connection between the pressing head 308 and the guiding sliding plate 307 ensures the appropriate pressing force. By accurately controlling the pressure and displacement, the interference fit accuracy between the magnetic ring material and the motor rotor is ensured.
