Description

Technical Field

[0001] The utility model relates to the technical field of motor accessory processing, in particular to a motor end cover grinding device. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction, and a motor end cover is a rear cover installed behind the casing of a motor, etc. The processing of motor end covers is generally carried out by stamping cold-rolled plates. After stamping, the outer wall of the end cover needs to be ground to make the outer wall of the end cover smooth and flat, so as to provide convenient conditions for subsequent spraying.

[0003] In the prior art, when grinding a motor end cover, it is mostly necessary to use a clamping mechanism to clamp and fix the end cover on a workbench, and then use a grinding device to grind the outer wall of the fixed end cover. However, during the process of grinding the outer wall of the end cover by the grinding device, the contact part between the end cover and the clamping mechanism cannot be effectively ground, resulting in certain grinding dead corners on the outer wall of the end cover. Therefore, it is necessary to frequently adjust the clamping position of the end cover to achieve comprehensive grinding of the end cover, resulting in a more cumbersome grinding process and a lower grinding efficiency. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a motor end cover grinding device that can automatically rotate and support, flexibly adapt to the size of the end cover, and has high grinding efficiency.

The edge grinding component 6 includes a base 61, a first telescopic arm 62, a third driving motor 63, a supporting wheel 64, a second telescopic arm 65, a fourth driving motor 66 and a grinding head 67. The first telescopic arms 62 are evenly arranged on the side wall of the base 61. The third driving motor 63 is arranged at the end of the first telescopic arm 62. The supporting wheel 64 is arranged on the third driving motor 63 and is fixedly connected to the output shaft of the third driving motor 63. The second telescopic arms 65 are evenly arranged on the side wall of the base 61. The fourth driving motor 66 is arranged at the end of the second telescopic arm 65. The grinding head 67 is arranged on the fourth driving motor 66 and is fixedly connected to the output end of the fourth driving motor 66.

[0025] Through the moving component 3, the telescopic component 4 and the edge grinding component 6, the outer surface of the motor end cover 7 is comprehensively ground. There is no need to frequently adjust the clamping position of the end cover, realizing an efficient and accurate automatic grinding process, shortening the operation time and improving the production efficiency. The first telescopic arm 62 flexibly extends and retracts according to the inner wall size of the motor end cover 7, so that the supporting wheel 64 abuts against the inner wall of the motor end cover 7. The second telescopic arm 65 flexibly extends and retracts according to the outer wall size of the motor end cover 7, so that the grinding head 67 abuts against the outer wall of the motor end cover 7. The third driving motor 63 drives the supporting wheel 64 to rotate, driving the motor end cover 7 to rotate. The fourth driving motor 66 drives the grinding head 67 to rotate, grinding the edge of the motor end cover 7. The moving component 3 and the telescopic component 4 enable the grinding disc 5 to flexibly move and extend on the top of the outer surface of the motor end cover. The driving motor 1 drives the grinding disc 5 to rotate, grinding the top of the motor end cover 7. Through the integrated multiple driving motors, the actions of each grinding part can be independently controlled, improving the grinding accuracy and consistency, reducing the error of manual operation, and ensuring the smoothness and flatness of the outer wall of the end cover.

[0026] The second telescopic arm 65 and the first telescopic arm 62 are arranged at intervals up and down. Through this design, the supporting wheel 64 and the grinding head 67 can better fix and stabilize the motor end cover 7, reduce the vibration during grinding, and ensure the grinding quality. By arranging at intervals, it is ensured that the supporting wheel 64 and the grinding head 67 will not interfere with each other during the grinding process, maintaining their respective effective operation ranges, and improving the accuracy and efficiency of grinding.

[0027] Preferably, as in the above embodiment, the outer surface of the support wheel 64 is covered with an anti-slip pad made of rubber material. The anti-slip pad effectively increases the friction when the support wheel 64 contacts the inner wall of the motor end cover 7, ensuring the stability of the motor end cover 7 without sliding and enhancing the stability of the entire grinding process. The rubber material is soft and has a certain elasticity. Wrapping it around the support wheel 64 reduces the direct hard metal-to-metal contact, preventing scratches or damage to the inner wall of the motor end cover 7 during the support and rotation processes and protecting the surface integrity of the end cover. The rubber anti-slip pad has good deformation ability and can adapt to the inner walls of motor end covers 7 with different sizes and shapes. By moderately squeezing and deforming, it closely adheres to the inner wall, providing a more fitting and stable support.

[0028] Preferably, as in the above embodiment, the height of the grinding head 67 is greater than the outer wall height of the motor end cover 7. With this design, the grinding head 67 covers the entire edge of the motor end cover 7 during the grinding process, ensuring the comprehensiveness and consistency of grinding.

The driving motor two 33 is arranged on the side wall of the fixed frame 31, and the output end of the driving motor two 33 is fixedly connected to the screw rod 32. The slider 34 is screwed onto the screw rod 32. With the fixed frame 31 as the basic frame of the moving component 3, the chute provided inside it guides the linear movement of the slider 34. The driving motor two 33 drives the screw rod 32 to rotate, driving the slider 34 to move, achieving precise positioning and trajectory control of the telescopic component 4, improving the flexibility and accuracy of grinding, enhancing work efficiency, and reducing the need for manual adjustment. It is an important part of realizing an efficient and automated grinding process.
