[0002] A hydraulic breaker is an important accessory for construction machinery such as excavators. It converts hydraulic energy into mechanical impact energy through a hydraulic system to break hard materials such as concrete and rock. These hydraulic breakers are typically mounted on excavators or other construction machinery and are widely used in mining, road construction, and building demolition. Their working principle involves a hydraulic pump driving a piston in reciprocating motion, which transmits the impact force through a chisel, thus breaking the object.

[0022] 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.

[0023] As shown in Figures 1-4, the technical solution adopted by this utility model is as follows: a hydraulic breaker cylinder polishing device. It includes a base 1. A support seat 2 is fixedly installed on the base 1. A guide block 16 is rotatably installed on the support seat 2, and the guide block 16 has a clearance hole. Preferably, the clearance hole is set as a through groove.

[0024] During polishing, the hydraulic breaker cylinder 11 is installed in the mounting slot, and the hydraulic breaker cylinder 11 can slide along the mounting slot. This allows the hydraulic breaker cylinder 11 to feed forward during the polishing process.

[0025] The guide block 16 and the support base 2 are connected by an annular limiting block 9.

[0026] Specifically, a second motor 12 is fixedly mounted on the base 1. The output shaft of the second motor 12 is horizontally arranged in the left-right direction. Both ends of the guide block 16 pass through the annular limiting block 9. A gear ring 10 is fixedly mounted on one end of the guide block 16 near the second motor 12. The gear ring 10 meshes with the second gear 13.

[0027] Furthermore, the longitudinal section of the annular limiting block 9 is set to be circular, the annular limiting block 9 is rotatably connected to the support base 2, the annular limiting block 9 is provided with a rectangular hole that runs through the left and right sides, the vertical section of the guide block 16 is set to be rectangular, and the guide block 16 is installed in the rectangular hole.

[0028] The second motor 12 is started. Through the meshing action of the gear ring 10 and the second gear 13, the second motor 12 drives the guide block 16 to rotate. The guide block 16 drives the annular limit block 9 to rotate together.

[0029] A clamping block 4 is slidably mounted on the guide block 16. Two clamping blocks 4 are configured and symmetrical about the axis of the guide block 16. The clamping blocks 4 and the guide block 16 are connected via a first drive module. The first drive module drives the clamping blocks 4 to move towards or away from each other.

[0030] Specifically, the clamping block 4 is installed at the end of the guide block 16 away from the second motor 12.

[0031] The first driving module includes a clamping cylinder 8, which is fixedly mounted on the guide block 16. The clamping block 4 is mounted on the output end of the clamping cylinder 8, and the clamping cylinder 8 drives the clamping block 4 to move towards or away from each other.

[0032] A clamping roller 15 with its axis arranged vertically is rotatably mounted on the clamping block 4. A second drive module for driving the clamping roller 15 to rotate is installed between the clamping roller 15 and the base 1.

[0033] The second drive module includes a tooth block 3 and a first gear 14.

[0034] The toothed block 3 is fixedly installed between the support plate 5 and the support base 2. The upper end of the toothed block 3 is provided with helical teeth 301, and the teeth of the helical teeth 301 are arranged in an arc shape.

[0035] The first gear 14 is coaxially fixedly mounted on the support plate 5. The axis of the first gear 14 is located on the cross section where the arc of the helical tooth 301 is located.

[0036] When the guide block 16 drives the clamping block 4 and the support plate 5 to rotate, the first gear 14 on the support plate 5 rotates downward to mesh with the helical gear 301. Since the helical gear 301 is fixed, the first gear 14 will rotate, thereby driving the clamping roller 15 to rotate. During polishing, since the clamping roller 15 is clamped to the breaker cylinder 11, the clamping roller 15 will drive the breaker cylinder 11 to move to achieve the feeding action.

[0037] A support plate 5 is fixedly installed on the base 1 at one end away from the support seat 2, and a grinding wheel 7 is rotatably installed on the support plate 5.

[0038] Furthermore, a first motor 6 is fixedly installed on the support plate 5, and the output shaft of the first motor 6 is coaxially and fixedly connected to the grinding wheel 7.

[0039] The principle of use of this application is as follows:

[0040] Place the hydraulic breaker cylinder 11 into the guide hole of the guide block 16. Start the clamping cylinder 8. The output end of the clamping cylinder 8 drives the clamping blocks 4 on both sides to move closer to each other. The clamping rollers 15 on the clamping blocks 4 contact the side wall of the hydraulic breaker cylinder 11 and are clamped under the action of the clamping cylinder 8.

[0041] Then, the first motor 6 is started. The rotation of the first motor 6 drives the grinding wheel 7 to rotate.

[0042] Simultaneously, the second motor 12 is started. The output end of the second motor 12 drives the second gear 13 to rotate, which in turn drives the gear ring 10 meshing with the second gear 13 to rotate, which in turn drives the guide block 16 fixed on the gear ring 10 to rotate on the support base 2 through the annular limit block 9.

[0043] During this process, because the clamping cylinder 8 is fixed on the guide block 16 and the clamping block 4 is fixedly connected to the output end of the clamping cylinder 8, the guide block 16 can drive the clamping cylinder 8 and the clamping block 4 to rotate when it rotates.

[0044] It is important to note here that the first motor 6 and the second motor 12 should have the same direction of rotation, described here as counterclockwise and clockwise from the perspective shown in Figure 3. Since both the first motor 6 and the second motor 12 rotate clockwise, the gear ring 10 meshing with the second gear 13 drives the guide block 16 to rotate counterclockwise. The counterclockwise rotation of the guide block 16 then drives the clamping roller 15 and the first gear 14 to rotate counterclockwise. At this time, the clamping roller 15 is fixed in place.

[0045] During the above process, the first motor 6 rotates clockwise, causing the grinding wheel 7 to rotate clockwise as well. Here, due to the reversing effect of the meshing of the second gear 13 and the second motor 12, the rotation direction of the breaker cylinder 11 is opposite to that of the grinding wheel 7, greatly improving grinding efficiency. The first gear 14 rotates counterclockwise to engage with the helical teeth 301 on the gear block 3. At this time, the helical teeth 301 drive the first gear 14, causing it to rotate against the damper. The rotation of the first gear 14 drives the clamping roller 15 to rotate. Since the surface of the clamping roller 15 is provided with friction material and the clamping roller 15 abuts against the wall of the breaker cylinder 11, the rotation of the clamping roller 15 drives the breaker cylinder 11 to move towards the first motor 6, thereby enabling the grinding wheel 7 to grind the inner wall of the breaker cylinder 11 deeper, further improving the practicality and convenience of the device.

[0046] After grinding is completed, the corresponding rotation directions can be reversed. At this time, the clamping roller 15 can slide the breaker cylinder 11 out of the guide hole of the guide block 16, and the clamping cylinder 8 is activated to release the clamping block 4 from the breaker cylinder 11. The ground breaker cylinder 11 can then be taken out.

[0047] Although the present invention 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 invention should be included within the protection scope of the present invention.
