[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a polishing device for taps, comprising:

[0031] The polishing mechanism includes a clamping component and a polishing component. It should be noted that the clamping component can quickly clamp and fix multiple taps 14, and the polishing component can quickly polish multiple taps 14, effectively improving the polishing efficiency of the taps 14.

[0032] The clamping assembly includes a drive disk 3, a ball 7, a spring 8, a hydraulic cylinder 9, a connector 10, an outer ring 11, and an inner ring 12;

[0033] The top of the drive disk 3 is provided with a first annular groove 4 and a second annular groove 5. The inner walls of the first annular groove 4 and the second annular groove 5 are slidably in contact with abutting blocks 6. It should be noted that a tap 14 is abutted and limited by two abutting blocks 6.

[0034] The clamping block 6 is fixedly connected to the ball 7. One end of the spring 8 is fixedly connected to the ball 7, and the other end of the spring 8 is fixedly connected to the inner wall of the first annular groove 4 or the inner wall of the second annular groove 5. The hydraulic rod of the hydraulic cylinder 9 is fixedly connected to the connecting piece 10. The bottom of the connecting piece 10 is fixedly connected to the outer ring 11 and the inner ring 12. The inner side of the outer ring 11 and the outer side of the inner ring 12 are both arc-shaped.

[0035] Using the aforementioned clamping assembly, the tops of multiple taps 14 are moved into the slots on the drive plate 3. The hydraulic cylinder 9 is activated, causing the connecting piece 10 to move downwards. The connecting piece 10 then moves the outer ring 11 and the inner ring 12 downwards. The arc-shaped section inside the outer ring 11 presses against the ball 7 in the first annular groove 4, and the arc-shaped section outside the inner ring 12 presses against the ball 7 in the second annular groove 5. The ball 7 presses against the spring 8 and moves the clamping block 6. This allows the two corresponding clamping blocks 6 to move towards each other, and the two clamping blocks 6 clamp against one tap 14. This allows multiple taps 14 to be simultaneously limited and fixed.

[0036] Specifically, the polishing assembly includes a top frame 1, a drive motor 2, a base frame 15, a lifting hydraulic cylinder 16, and a polishing sand cylinder 17. The drive motor 2 and the hydraulic cylinder 9 are both fixedly mounted on the top frame 1. The output end of the drive motor 2 is fixedly connected to the drive plate 3. The lifting hydraulic cylinder 16 is fixedly mounted on the base frame 15. The hydraulic rod of the lifting hydraulic cylinder 16 is fixedly connected to the polishing sand cylinder 17.

[0037] Using the aforementioned clamping assembly, the lifting hydraulic cylinder 16 is activated, which drives the polishing sand cylinder 17 to move upward, so that the top of the polishing sand cylinder 17 contacts the drive disk 3. This allows the tap 14 to be inserted into the polishing sand inside the polishing sand cylinder 17. Then, the drive motor 2 is activated, which drives the drive disk 3 to rotate. The drive disk 3 drives the taps 14 after they are limited to rotate. Through the cooperation between the taps 14 and the polishing sand, multiple taps 14 can be polished simultaneously.

[0038] Specifically, the bottom of the drive disk 3 has multiple slots, in which taps 14 are fitted. Below the drive disk 3 is a placement seat 13, in which taps 14 are fitted with placement seats 13.

[0039] Using the clamping assembly described above, multiple taps 14 are inserted into the slots via the placement seat 13. After the taps 14 are fixed, the placement seat 13 is removed. After the taps 14 are polished, the multiple taps 14 can be removed via the placement seat 13.

[0040] Specifically, the polishing sand cylinder 17 contains polishing sand, which is used to facilitate the polishing of the tap 14.

[0041] Specifically, the top of the top frame 1 has mounting holes, which facilitates fixing the top frame 1 in a designated area.

[0042] Specifically, both the inner walls of the first annular groove 4 and the second annular groove 5 are provided with movable holes, and the abutting block 6 is slidably installed in the movable holes. It should be noted that this facilitates the movement of the abutting block 6.

[0043] Specifically, the polishing sand cylinder 17 is located directly below the drive disk 3, the outer ring 11 is located directly above the first annular groove 4, and the inner ring 12 is located directly above the second annular groove 5. It should be noted that this is to facilitate the outer ring 11 to move into the first annular groove 4 and the inner ring 12 to move into the second annular groove 5.

[0044] Working principle:

[0045] S1: Insert multiple taps 14 into the slots through the placement seat 13. After the taps 14 are fixed, remove the placement seat 13 and start the hydraulic cylinder 9. The hydraulic cylinder 9 drives the connecting piece 10 to move down. The connecting piece 10 drives the outer ring 11 and the inner ring 12 to move down. The arc-shaped section on the inner side of the outer ring 11 will squeeze the ball 7 in the first annular groove 4. The arc-shaped section on the outer side of the inner ring 12 will squeeze the ball 7 in the second annular groove 5. The ball 7 squeezes the spring 8 and drives the pressing block 6 to move. In this way, the two corresponding pressing blocks 6 can move towards each other. The two pressing blocks 6 press against one tap 14. In this way, multiple taps 14 can be limited and fixed simultaneously.

[0046] S2: Start the lifting hydraulic cylinder 16. The lifting hydraulic cylinder 16 drives the polishing sand cylinder 17 to move upward, so that the top of the polishing sand cylinder 17 contacts the drive disk 3. This allows the tap 14 to be inserted into the polishing sand inside the polishing sand cylinder 17. Then start the drive motor 2. The drive motor 2 drives the drive disk 3 to rotate. The drive disk 3 drives the taps 14 after the limit to rotate. Through the cooperation of the taps 14 and the polishing sand, multiple taps 14 can be polished simultaneously. When the drive disk 3 rotates, the ball 7 can rotate. The ball 7 can move around the arc-shaped section inside the outer ring 11 or outside the inner ring 12.

[0047] S3: After polishing is completed, start the lifting hydraulic cylinder 16 to move the polishing sand cylinder 17 back to its original position, place the placement seat 13 under the drive plate 3, release the limit on the tap 14, and let the tap 14 fall into the placement seat 13. Multiple taps 14 can be taken out through the placement seat 13, which can effectively improve the polishing efficiency of the tap 14.

[0048] The polishing device for taps provided by this utility model has been described in detail above. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
