Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a polishing device for processing the housing of a permanent magnet motor. Background Technology

[0002] Polishing is a crucial step in the processing of permanent magnet motor housings. A Chinese patent (publication number: CN217019899U) discloses a motor housing polishing device for ultrasonic motor processing, comprising a base with a groove on its top surface. A grinding roller in the device is fixed to the motor by bolts and nuts. The polishing effect is achieved through the rotation of the grinding roller and its contact friction with the motor housing. However, this device still has certain shortcomings in use and needs further improvement.

[0003] In existing polishing devices, the bolt and nut fixing method is cumbersome and requires a lot of time and manpower. During the polishing process, if it is necessary to change to abrasive rollers of different coarseness or to maintain and replace the abrasive rollers, the operator needs to disassemble the bolts and nuts. This not only increases the difficulty of operation but also reduces work efficiency. Moreover, due to the large vibration and friction generated during the polishing process, the bolts and nuts are prone to loosening, causing the abrasive rollers to fall off or loosen. This not only affects the polishing effect but may also cause injury to the operator. Utility Model Content

[0004] The purpose of this utility model is to provide a polishing device for processing the housing of a permanent magnet motor. The device allows for easy assembly and disassembly of the grinding roller through the use of a sleeve and a limiting block, thus solving the problem of the cumbersome process of replacing the grinding roller during polishing.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a polishing device for processing the housing of a permanent magnet motor. It includes a worktable with a transmission mechanism and a three-jaw chuck. A sleeve is mounted on the transmission mechanism, and a through groove is formed inside the sleeve. A sleeve rod is slidably fitted within the through groove, and a grinding roller is mounted at the bottom of the sleeve rod. A baffle is slidably fitted inside the through groove, contacting the top of the sleeve rod. A spring connects the baffle to the inner wall of the through groove. Three limit blocks are mounted on the sleeve rod, and a limit groove is formed inside the sleeve to mate with the three limit blocks. A vertical rod is mounted at the bottom of the sleeve, and a ring is mounted on the sleeve rod. An arc-shaped groove is formed on the ring to mate with the vertical rod.

[0007] Furthermore, the sleeve has three L-shaped grooves, and each of the three L-shaped grooves is connected to a limiting groove, and the three limiting blocks are slidably fitted in the L-shaped grooves.

[0008] Furthermore, the transmission mechanism has a linear module, which is mounted on the worktable.

[0009] Furthermore, a flat plate is installed at the output end of the linear module, and a motor is installed on the flat plate. The output end of the motor is connected to the sleeve.

[0010] Furthermore, a vacuum cleaner body is installed on the workbench, a suction pipe is installed at the suction end of the vacuum cleaner body, and an expansion tube is installed at the end of the suction pipe.

[0011] Furthermore, a support plate is installed on the workbench, and a through hole is opened in the support plate, with the expansion bucket installed in the through hole.

[0012] This utility model has the following beneficial effects:

[0013] This invention facilitates the easy assembly and disassembly of the grinding roller using a sleeve and a limiting block. This makes the assembly and disassembly of the grinding roller simple and quick, significantly reducing the time required to replace the grinding roller and improving the overall efficiency of the polishing operation. Furthermore, since the grinding roller can be easily replaced, a suitable grinding roller can be selected according to different polishing needs, thereby ensuring the uniformity and consistency of the polishing effect. This is of great significance for improving the surface quality, wear resistance, and corrosion resistance of the permanent magnet motor housing, while also avoiding the problem of bolt loosening caused by vibration and friction.

[0014] This invention stabilizes the grinding roller using a vertical rod and a circular ring, ensuring that the grinding roller maintains the correct position and angle during the polishing process. This avoids uneven or over-polishing caused by misalignment, which helps improve the polishing precision of the permanent magnet motor housing, making its surface smoother and more uniform, meeting higher quality requirements, and protecting the motor housing and other components of the polishing device, extending their service life.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a polishing device for processing the casing of a permanent magnet motor, including a worktable 1, a vacuum cleaner body 4 mounted on the worktable 1, a suction pipe 401 mounted on the suction end of the vacuum cleaner body 4, and an expansion bucket 402 mounted at the end of the suction pipe 401. When polishing the casing of the permanent magnet motor, the vacuum cleaner body 4 is activated, and the debris generated during polishing is sucked into the vacuum cleaner body 4 through the expansion bucket 402 from the suction pipe 401 for collection. A support plate 403 is mounted on the worktable 1, and a through hole is opened in the support plate 403. The expansion bucket 402 is installed in the through hole, and the suction pipe 401 is supported by the support plate 403. A transmission mechanism 2 is provided on the worktable 1. The transmission mechanism 2 has a linear module 201, which is mounted on the worktable 1. A plate 202 is mounted on the output end of the linear module 201, and a motor 203 is mounted on the plate 202. The output end of the motor 203 is connected to the sleeve 5. The linear module 201 can drive the grinding roller 13 to move up and down, and the motor 203 drives the grinding roller 13 to rotate to polish the permanent magnet motor housing. A three-jaw chuck 3 is mounted on the worktable 1, and a sleeve 5 is mounted on the transmission mechanism 2. A through groove 501 is opened in the sleeve 5, and a sleeve rod 6 is slidably fitted in the through groove 501. There are three L-shaped grooves 502 in the sleeve 5, and the three L-shaped grooves 502 are respectively connected to three limiting grooves 503. The sleeve 6 has a grinding roller 13 installed at the bottom end. A baffle 8 is slidably fitted inside the through groove 501, and the baffle 8 contacts the top of the sleeve 6. A spring 7 is connected between the baffle 8 and the inner wall of the through groove 501. Three limiting blocks 9 are installed on the sleeve 6. A limiting groove 503 is opened inside the sleeve 5 to cooperate with the three limiting blocks 9. When disassembling the grinding roller 13, pushing the grinding roller 13 upward will drive the sleeve 6 to push the baffle 8 to slide along the through groove 501. At this time, the limiting block 9 moves from the bottom of the limiting groove 503 to the top of the limiting groove 503 and is flush with the L-shaped groove 502. The baffle 8 compresses the spring 7. Then, rotating the grinding roller 13 will drive the sleeve 6 to... The limiting block 9 moves from the limiting groove 503 into the L-shaped groove 502. At this time, pulling the abrasive roller 13 to the bottom will slide the limiting block 9 out of the L-shaped groove 502. The sleeve rod 6 can be removed from the through groove 501 to disassemble and replace the abrasive roller 13. During installation, first, the sleeve rod 6 is inserted into the through groove 501 and the limiting block 9 is aligned with the L-shaped groove 502. Then, the abrasive roller 13 is moved to the top to move the limiting block 9 to the top of the L-shaped groove 502. At this time, the sleeve rod 6 pushes the baffle 8 to compress the spring 7. Then, the abrasive roller 13 is rotated to move the limiting block 9 into the limiting groove 503. The abrasive roller 13 is released and the spring 7 pushes the baffle 8 to move the sleeve rod 6 to move the limiting block 9 to the bottom of the limiting groove 503, thus completing the installation of the abrasive roller 13.

[0023] A vertical rod 10 is installed at the bottom of the sleeve 5, and a ring 11 is installed on the sleeve rod 6. An arc-shaped groove 12 that mates with the vertical rod 10 is opened on the ring 11. When the grinding roller 13 is installed, the vertical rod 10 enters the arc-shaped groove 12 for limitation. When the sleeve 5 is rotated by the motor 203, the sleeve rod 6 drives the grinding roller 13 to rotate. During this process, the vertical rod 10 is limited by the ring 11 within the arc-shaped groove 12, so as to prevent the grinding roller 13 from shifting when it is working.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
