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. Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a guide sleeve inner wall fine polishing device, including a clamping component 1, two clamping components 1 are provided, a grinding component 4 is provided above the two clamping components 1, a connecting component 6 is fixedly connected to the outside of the grinding component 4, a plurality of support components 2 are provided below the two clamping components 1, the connecting component 6 and the two clamping components 1 and the plurality of support components 2 are connected by a cleaning lighting device 3, and an auxiliary noise reduction device 5 is provided on the top outer side of the connecting component 6;

[0023] The cleaning lighting device 3 includes a support box 31, a connecting component 6, and two clamping components 1 connected to multiple support components 2 via the support box 31. A mesh block 32 is fixedly installed on the top of the support box 31, a filter cloth 34 is fixedly installed on the inner side of the support box 31, multiple fans 35 are fixedly installed on one side of the support box 31, and a lighting component 36 is fixedly installed above the support box 31 and on one side of the two clamping components 1.

[0024] Specifically, the height and width of the inner side of the support box 31 are equal to the height and width of the outer side of the filter cloth 34.

[0025] By adopting the above technical solution, the device can ensure that the inner side of the support box 31 and the outer side of the filter cloth 34 are in close contact with each other, thereby preventing gaps between the inner side of the support box 31 and the outer side of the filter cloth 34 and ensuring normal filtration.

[0026] Specifically, a sealing door 33 is provided on the side of the support box 31 away from the multiple fans 35.

[0027] By adopting the above technical solution, staff can open the sealed door 33 to remove dust and debris from the support box 31 when needed, thereby reducing inconvenience and better meeting work needs.

[0028] Specifically, the support box 31 and the sealing door 33 are connected by a hinge.

[0029] By adopting the above technical solution, the staff can open and close the sealed door 33 normally, thereby ensuring that the removal of dust and debris can be carried out normally, and thus better meeting the needs of the work.

[0030] Specifically, the lighting assembly 36 includes a vertical plate 362, which is fixedly installed above the support box 31 and on one side of the two clamping assemblies 1. A transparent shell 364 is provided between the vertical plate 362 and the grinding assembly 4, and multiple lighting lamps 363 are fixedly installed on the inner side of the transparent shell 364.

[0031] By adopting the above technical solution, staff can use the 363 lighting lamp for auxiliary lighting when needed, thereby better coping with situations of insufficient light and ensuring the normal progress of work.

[0032] Specifically, the upright plate 362 and the transparent shell 364 are connected by an electric telescopic rod 361.

[0033] By adopting the above technical solution, staff can adjust the position of the transparent shell 364 and the lighting lamp 363 by means of the electric telescopic rod 361 when needed, thereby adjusting the position of the auxiliary lighting.

[0034] In this embodiment, when the device is needed to perform fine polishing on the inner wall of the guide sleeve, the operator places the guide sleeve above the mesh block 32 in the cleaning lighting device 3, and activates the two clamping components 1 to clamp the guide sleeve. If the light is insufficient, the electric telescopic rod 361 on the upright plate 362 in the lighting component 36 can be activated to adjust the position of the transparent shell 364 and the lighting lamp 363. Then, each lighting lamp 363 is activated for auxiliary lighting. Afterward, the operator manipulates the polishing component 4 on the connecting component 6 to perform fine polishing on the inner wall of the guide sleeve. During this process, the operator can activate each fan 35. The debris and dust generated during the processing pass through the mesh block 32 and enter the support box 31 under the action of each fan 35, and are then blocked by the filter cloth 34, thereby cleaning the debris and dust. After the processing is completed, all structures are closed. After the work is finished, the operator can open the sealing door 33 to remove the debris and dust. The support component 2 plays a supporting role. Example 2

[0035] The difference between this embodiment and embodiment 1 is that the auxiliary noise reduction device 5 includes a support plate 51. The support plate 51 is fixedly installed on one side of the top of the connecting component 6. A lifting cover 54 is provided below the support plate 51 and located outside the grinding component 4 and below the top of the connecting component 6. The support plate 51 and the lifting cover 54 are connected by an electric lifting rod 52. Sound-absorbing cotton 53 is fixedly installed in the side wall of the lifting cover 54.

[0036] By adopting the above technical solution, staff can reduce noise during fine polishing by using the combination of sound-absorbing cotton 53 and electric lifting rod 52 when needed, thereby reducing the possibility of discomfort to people in the surrounding area.

[0037] In this embodiment, during fine polishing, the operator can activate the electric lifting rod 52 on the support plate 51 of the auxiliary noise reduction device 5, thereby driving the lifting cover 54 to descend to the outside of the guide sleeve and the lower end of the grinding component 4. Then, the noise during fine polishing is reduced by the sound-absorbing cotton 53, thereby reducing the possibility of discomfort to the surrounding people.

[0038] The structure and principle of the clamping assembly 1 (composed of a first electric push rod and clamping plates), the support assembly 2 (composed of a support rod and a support base), the grinding assembly 4 (composed of a hydraulic cylinder, a first mounting plate, a motor, a second mounting plate, and an adjustable grinding assembly), and the connecting assembly 6 (composed of a side plate and a top plate) in this utility model have been disclosed in a guide sleeve inner wall fine polishing device disclosed in Chinese patent application number 202222551298.8. Its working principle is as follows: First, the guide sleeve to be ground is placed between two clamping plates. Then, the output end of the first electric push rod extends and retracts, thereby moving the two clamping plates closer together, thus fixing the guide sleeve between the two clamping plates. Next, the output end of the hydraulic cylinder extends and retracts, thereby moving the arc-shaped grinding plate downwards, placing the arc-shaped grinding plate inside the guide sleeve. Then, the output end of the second electric push rod extends and retracts. Because the arc-shaped grinding plate has second grooves at both its upper and lower ends, and the inner walls of the two second grooves are rotatably mounted... The second rotating shaft, with the tops of the first and second connecting rods respectively positioned on the sides of the two rotating shafts, causes the two arc-shaped grinding plates to expand outwards, fitting against the inner wall of the guide sleeve. The motor output then rotates, causing the arc-shaped grinding plates to rotate and polish the inner wall of the guide sleeve. The outward expansion distance of the arc-shaped grinding plates can be adjusted arbitrarily, enabling the polishing of guide sleeve inner walls of different diameters, thus improving the polishing efficiency of the device. Because the second electric push rod extends and retracts, and because the arc-shaped grinding plates have second grooves at both ends, with second rotating shafts rotatably mounted between the inner walls of the two second grooves, and the tops of the first and second connecting rods respectively positioned on the sides of the two rotating shafts, the two arc-shaped grinding plates expand outwards, fitting against the inner wall of the guide sleeve, resulting in the ability to polish guide sleeve inner walls of different diameters, further improving the polishing efficiency of the device.

[0039] The working principle and usage process of this utility model are as follows: When the device is needed to perform fine polishing on the inner wall of the guide sleeve, the operator places the guide sleeve above the mesh block 32 in the cleaning lighting device 3, and activates the two clamping components 1 to clamp the guide sleeve. If the light is insufficient, the electric telescopic rod 361 on the upright plate 362 in the lighting component 36 can be activated to adjust the position of the transparent shell 364 and the lighting lamp 363. Then, each lighting lamp 363 is activated for auxiliary lighting. Afterward, the operator manipulates the polishing component 4 on the connecting component 6 to perform fine polishing on the inner wall of the guide sleeve. During this process, the operator can activate each fan 35. The generated debris and dust pass through the mesh block 32 and enter the support box 31 under the action of each fan 35, and are then blocked by the filter cloth 34, thereby cleaning the debris and dust. After the processing is completed, all structures are closed. After the work is finished, the staff can open the sealed door 33 to remove the debris and dust. The support component 2 plays a supporting role. During the fine polishing process, the staff can activate the electric lifting rod 52 on the support plate 51 in the auxiliary noise reduction device 5, thereby driving the lifting cover 54 to descend to the outside of the guide sleeve and the lower end of the grinding component 4. Then, the noise during the fine polishing process is reduced by the sound-absorbing cotton 53, thereby reducing the possibility of discomfort to the surrounding personnel.
