[0021] This utility model provides, for example Figures 1 to 3 The fine grinding fixture inside the breaker cylinder shown includes a base plate 1, on which a first mounting bracket 3 and a second mounting bracket 4 are fixedly mounted. A collection box 2 is disposed between the first mounting bracket 3 and the second mounting bracket 4, and the collection box 2 is fixedly connected to the base plate 1.

[0022] A grinding mechanism is mounted on the first mounting bracket 3. The grinding mechanism includes a cylinder 5, which is fixed on the first mounting bracket 3.

A first motor 7 is fixedly mounted on one of the supports, and the output shaft of the first motor 7 is coaxially fixedly connected to the rotating shaft 9 on that support. In this embodiment, the first motor 7 has a brake device.

[0024] The grinding table 8 is a square table with a mounting cavity 23 inside.

The two third sliding grooves 16 are symmetrical about the mounting cavity 23, and the first sliding groove 10 and the second sliding groove 11 are also symmetrical about the mounting cavity 23. The first sliding groove 10, the second sliding groove 11, and the two third sliding grooves 16 are arranged in a cross shape.

[0025] The first slide groove 10, the second slide groove 11, and the third slide groove 16 are all inverted T-shaped grooves. A matching slider 12 in the shape of an inverted T is slidably installed in each of the first slide groove 10, the second slide groove 11, and the two third slide grooves 16.

[0026] A power mechanism is installed on the grinding table 8. The power mechanism is connected to the sliders 12 in the two third slide grooves 16 to drive the sliders 12 in the two third slide grooves 16 to slide relative to each other.

[0027] The power mechanism includes a double-acting lead screw 15, which passes through the mounting cavity 23 and is rotatably connected to the grinding table 8. Two threaded sections on the double-acting lead screw 15 correspond one-to-one with two third sliding grooves 16, with each threaded section located within its corresponding third sliding groove 16. Each threaded section of the double-acting lead screw 15 passes through and is threadedly connected to a slider 12 within its corresponding third sliding groove 16.

[0028] A second motor 17 is fixedly installed on the grinding table 8, and the output shaft of the second motor 17 is coaxially and fixedly connected to the bidirectional lead screw 15.

[0029] The linkage component is installed in the mounting cavity 23. The linkage component is driven by the bidirectional lead screw 15 of the power mechanism. The linkage component is also driven by the slider 12 in the first slide groove 10 and the second slide groove 11 to drive the slider 12 in the first slide groove 10 and the second slide groove 11 to slide relative to each other.

[0030] The linkage assembly includes a first bevel gear 20, a second bevel gear 21, a third bevel gear 22, a first lead screw 13, and a second lead screw 14. The first lead screw 13 is located in the first slide groove 10, and the second lead screw 14 is located in the second slide groove 11. Both the first lead screw 13 and the second lead screw 14 are rotatably connected to the grinding table 8. The first lead screw 13 and the second lead screw 14 are coaxially opposite each other about the mounting cavity 23, and the proximal ends of the first lead screw 13 and the second lead screw 14 both pass into the mounting cavity 23.

[0031] The end of the first lead screw 13 located in the mounting cavity 23 is coaxially fixedly connected to the first bevel gear 20, and the end of the second lead screw 14 located in the mounting cavity 23 is coaxially fixedly connected to the second bevel gear 21. The third bevel gear 22 is fixedly sleeved on the bidirectional lead screw 15, and both the first bevel gear 20 and the second bevel gear 21 mesh with the third bevel gear 22.

[0032] The first lead screw 13 passes through the slider 12 in the first slide groove 10 and is threadedly connected to the slider 12. The second lead screw 14 passes through the slider 12 in the second slide groove 11 and is threadedly connected to the slider 12.

[0033] The sliding direction of the slider 12 in the first slide groove 10 and the second slide groove 11 is perpendicular to the sliding direction of the slider 12 in the two third slide grooves 16.

[0034] Each of the four sliders 12 is fixedly connected to a clamping block 18, and the breaker cylinder is placed between the four clamping blocks 18. Each of the four clamping blocks 18 near the end of the breaker cylinder is fixedly fitted with an anti-slip pad 19 made of rubber material.

[0035] Working principle: When using this grinding fixture, the breaker cylinder body is placed on the grinding table 8 using existing transportation methods such as hoisting. At this time, the grinding table 8 is in a horizontal state, and the breaker cylinder body is located on top of the grinding table 8 and placed between the four clamping blocks 18.

[0036] Next, the second motor 17 is started. The output shaft of the second motor 17 drives the bidirectional lead screw 15 to rotate, and the bidirectional lead screw 15 pushes the corresponding two sliders 12 to slide closer to the mounting cavity 23. At the same time, the bidirectional lead screw 15 drives the third bevel gear 22 to rotate, and the third bevel gear 22 pushes the first bevel gear 20 and the second bevel gear 21 to rotate synchronously. The first bevel gear 20 drives the first lead screw 13 to rotate, and the first lead screw 13 pushes the corresponding slider 12 to slide along the first slide groove 10 closer to the mounting cavity 23. The second bevel gear 21 drives the second lead screw 14 to rotate, and the second lead screw 14 pushes the corresponding slider 12 to slide along the second slide groove 11 closer to the mounting cavity 23.

[0037] During this process, the four sliders 12 move toward the mounting cavity 23 in sync, and at the same time, the four sliders 12 drive the four clamping blocks 18 to move toward the breaker cylinder in sync.

[0038] After the four clamping blocks 18 clamp the breaker cylinder body, the second motor 17 is turned off. Then, the first motor 7 is started. The output shaft of the first motor 7 drives the corresponding rotating shaft 9 to rotate, which in turn drives the grinding table 8 to rotate 90 degrees. The grinding table 8, through the four clamping blocks 18, drives the breaker cylinder body to revolve 90 degrees around the rotating shaft 9. At this time, the breaker cylinder body is aligned with the grinding head 6, and the first motor 7 is turned off simultaneously.

[0039] Then, cylinder 5 is started, and the telescopic shaft of cylinder 5 extends and drives the grinding head 6 to move into the cylinder body of the breaker hammer. The grinding head 6 performs fine grinding on the inside of the breaker hammer cylinder body.

[0040] After the grinding is completed, the telescopic shaft of cylinder 5 retracts, causing the grinding head 6 to slide out of the breaker cylinder. Then, the output shaft of the first motor 7 rotates again, and the breaker cylinder rotates downwards towards the collection box 2. After that, the breaker cylinder tilts, and the grinding debris inside the breaker cylinder slides into the collection box 2 for collection.

[0041] After all the debris has been emptied from the breaker cylinder, the output shaft of the first motor 7 reverses, and the grinding table 8 rotates to a horizontal position. Finally, the first motor 7 is turned off, and the second motor 17 is started. The output shaft of the second motor 17 reverses relative to when the breaker cylinder is clamped. At this time, the double-acting lead screw 15 reverses, and the first lead screw 13 and the second lead screw 14 reverse. The four sliders 12 slide away from the mounting cavity 23, causing the four clamping blocks 18 to slide away from the breaker cylinder. Then, the breaker cylinder is removed from the grinding table 8, and the second motor 17 is turned off.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
