Description

Technical Field

[0001] This utility model relates to the field of rotor grinding and processing, specifically a tooling for grinding the outer periphery of a rotor. Background Technology

[0002] Motor rotors are divided into two types: internal rotor rotation and external rotor rotation. In the internal rotor rotation type, the core in the middle of the motor is the rotating body, outputting torque or receiving energy. In the external rotor rotation type, the outer body of the motor is the rotating body. Different types facilitate applications in various occasions. During long-term use, due to factors such as friction, thermal expansion, and high-load working conditions, a wear layer will gradually form on the surface of the motor rotor. This wear layer not only affects the normal operation of the motor, but may also cause unstable operation or noise. Grinding tools can effectively remove these wear layers, restore the rotor surface to a smooth surface, and thus ensure the stable operation of the motor.

[0003] Existing grinding fixtures require fixing the motor rotor before grinding it. However, the angle of the fixed motor rotor is not easy to adjust, which limits the grinding range of the grinding roller and reduces the grinding efficiency of the motor rotor. Therefore, a new fixture for grinding the outer circumference of the rotor is proposed to address the above problems. Utility Model Content

[0034] Working principle: During use, the operator inserts the motor rotor into the mounting housing 204 and activates the electric telescopic rod 206 using an external control switch. The telescopic end of the electric telescopic rod 206 drives one end of the two connecting rods 207 downward, while the other end of the two connecting rods 207 pulls the two positioning rods 208 to move in opposite directions. As the two positioning rods 208 move in opposite directions, they drive the two fixing rods 209 to move in opposite directions. The two fixing rods 209, in turn, compress the spring 214 and drive the two limit rods 210 to move in opposite directions. The two limit rods 210 clamp and position the surface of the motor rotor. After the motor rotor is positioned, the operator activates the hydraulic cylinder 4 using an external control switch. The telescopic end of the hydraulic cylinder 4 drives the fixing frame 5 downward. As the fixing frame 5 moves downward, it drives the grinding rollers 6 downward. After the two grinding rollers 6 have moved to the designated position, the operator activates the first motor 8 and the second motor 201 using an external control switch. The first motor 8... The output end drives one of the grinding rollers 6 to rotate. When the grinding roller 6 rotates, it drives one of the synchronous pulleys 7 to rotate. When the synchronous pulley 7 rotates, it drives the belt to drive the other synchronous pulley 7 and the grinding roller 6 to rotate, thus grinding the surface of the motor rotor. At the same time, the output end of the second motor 201 drives the first gear 202 to rotate. When the first gear 202 rotates, it drives the second gear 203 to rotate. When the second gear 203 rotates, it drives the mounting shell 204 to rotate. When the mounting shell 204 rotates, it drives the motor rotor to rotate, which can adjust the angle of the motor rotor, thereby improving the grinding efficiency of the motor rotor. After the grinding is completed, the operator uses an external control switch to start the electric telescopic rod 206. The telescopic end of the electric telescopic rod 206 drives one end of the two connecting rods 207 to move upward. At this time, the reaction force of the spring 214 drives the two fixed rods 209 and the limit rod 210 to move in the opposite direction, thus completing the disassembly of the motor rotor.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
