Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 - Figure 4, the present utility model provides a technical solution: a grinding tool for the outer circle of a blind plate, including a bottom box 1. A chute 10 is opened at the top of the bottom box 1, and a sliding plate 12 is slidably connected in the chute 10. Two support plates 6 are connected to the top of the sliding plate 12, and the same protective shell 2 is connected between the two support plates 6. A driving part 3 is fixedly installed on one side of the protective shell 2, and the output end of the driving part 3 extends into the protective shell 2 and is connected with a grinding wheel 7. A connection groove is opened on one side of the protective shell 2, and a protective device 5 is arranged in the connection groove. The protective device 5 includes two built-in grooves 507, and the built-in grooves 507 are opened on one side of the connection groove. A protective plate 502 is slidably connected in the built-in groove 507. Two springs 504 are connected to the bottom of the protective plate 502, and the other ends of the springs 504 are connected to the bottom inner wall of the built-in groove 507. One side of the protective plate 502 is connected with an extrusion inclined plate 501. Two support grooves are opened at the top of the protective plate 502, and a support rod 505 is slidably connected in the support groove. The other end of the support rod 505 is connected to the bottom inner wall of the built-in groove 507, and the spring 504 is sleeved on the outer wall of the corresponding support rod 505. Sliding grooves 506 are opened on both sides of the inner wall of the built-in groove 507, and sliding blocks 503 are slidably connected in the sliding grooves 506. One side of the sliding block 503 is connected with one side of the protective plate 502. A through groove 8 is opened at the bottom of the chute 10, and an electric push rod 9 is fixedly installed on one side of the inner wall of the through groove 8. The ejector rod of the electric push rod 9 is connected with a connection block 11. The top of the connection block 11 is connected with the bottom of the sliding plate 12, and the outer wall of the connection block 11 is slidably connected with the inner wall of the through groove 8. An impurity outlet is opened at the bottom of the protective shell 2.

[0026] Specific implementation method: By setting the spring 504, when the device is not in use, the two protective plates 502 are driven to close each other by the elastic force of the spring 504, thereby closing the protective shell 2, avoiding damage to the grinding wheel 7 caused by external bumps and affecting the grinding effect. By setting the support rod 505, through the support of the support rod 505, the spring 504 is prevented from bending and shaking during compression, thereby affecting the resilience of the spring 504. By setting the impurity outlet at the bottom of the protective shell 2, the waste chips are collectively discharged from the impurity outlet during grinding, making subsequent collection more convenient. By setting the two threaded sections with opposite directions on the outer wall of the double-threaded rod 406, the moving amounts of the two threaded seats 407 are ensured to be consistent when moving, thereby ensuring that the blind plate is centered when clamping the blind plate.

[0027] A drive module 13 is embedded at the top of the bottom box 1, and a fixing device 4 is connected to the top of the drive module 13. The fixing device 4 includes a bottom block 405. The bottom of the bottom block 405 is connected to the top of the drive module 13. A fixing groove 408 is formed at the top of the bottom block 405. A second motor 404 is fixedly installed on one side of the bottom block 405. The output shaft of the second motor 404 extends into the fixing groove 408 and is connected to a double-threaded rod 406. Two threaded seats 407 are threadedly connected to the outer wall of the double-threaded rod 406. A moving plate 403 is connected to the top of the threaded seat 407. A first motor 401 is fixedly installed on one side of one of the moving plates 403. A bearing is embedded in the moving plate 403, and a rotating shaft is rotatably connected in the bearing. One end of the rotating shaft is connected to a clamping plate 402, and the other end of one of the rotating shafts is connected to the output shaft of the first motor 401. The outer wall of the threaded seat 407 is slidably connected to the inner wall of the fixing groove 408. The bottom of the moving plate 403 is in contact with and slidably connected to the top of the bottom block 405. The other end of the double-threaded rod 406 is rotatably connected to one side of the inner wall of the fixing groove 408. Rubber pads are connected to one side of the opposite surfaces of the two clamping plates 402.

[0028] In the specific implementation manner, by providing the rubber pad on one side of the clamping plate 402, the clamping plate 402 and the blind plate are buffered by the rubber pad, avoiding direct hard contact between the clamping plate 402 and the blind plate and damaging the surface of the blind plate. Moreover, the rubber pad can also increase the friction force to prevent the blind plate from slipping. By providing the drive module 13, the fixed blind plate can be finely adjusted to align the blind plate with the grinding wheel 7.

[0029] Working principle: During use, place the blind plate between the two clamping plates 402. Drive the double-threaded rod 406 to rotate through the second motor 404, so that the double-threaded rod 406 drives the two threaded seats 407 to move. Further, the threaded seats 407 drive the moving block plate to move, and the moving plate 403 drives the clamping plate 402 to move, so that the two clamping plates 402 fix the blind plate. Then drive the connecting block 11 to move through the ejector rod of the electric push rod 9, and the connecting block 11 drives the sliding plate 12 to move. Further, the sliding plate 12 drives the protective shell 2 to move through the support plate 6. When the edge of the blind plate contacts and drives the extrusion inclined plate 501, the extrusion inclined plate 501 drives the protective plate 502 to move through extrusion. Further, the two protective plates 502 are separated, and then the grinding wheel 7 contacts the edge of the blind plate. Then drive the grinding wheel 7 to rotate through the driving part 3 to grind the blind plate.
