[0023] 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.

[0024] Reference Figures 1-2The present invention provides an embodiment of a bolt polishing device, comprising a processing table 1, which supports the equipment; a splash guard 2 is fixedly connected to the outer wall of the processing table 1 to protect the polishing liquid from splashing; a filter assembly 6 is provided at the center of the upper surface of the processing table 1; a collection chamber 3 is fixedly installed on the lower surface of the processing table 1 to collect bolt debris during the polishing process; a purifier 7 is fixedly installed on the rear surface of the collection chamber 3 to purify the waste liquid during the polishing process; and a robotic arm 4 is fixedly installed at the rear end of the upper surface of the processing table 1, with a polishing assembly 5 at the end of the robotic arm 4.

[0025] Reference Figures 1-3 After positioning and fixing the processing bolt by comparing the fixing components in the document, the processing bolt is adjusted to the designated processing area of ​​the polishing disc 59, and then the polishing assembly 5 is started. The outer wall of the processing bolt is polished by the operation of the polishing disc 59 in the housing 51. The polishing assembly 5 includes a housing 51, which is detachably connected to the end of the robotic arm 4. A gear seat 56 is rotatably connected to the lower surface of the housing 51. Multiple sets of protective strips 57 are fixedly connected to the outer side of the lower surface of the gear seat 56. A support plate 58 is hinged to the bottom end of the protective strips 57. The polishing disc 59 is detachably connected to the axis of the lower surface of the housing 51. During the polishing process of the processing bolt, the debris generated is sprayed with water to suppress the flying debris and prevent the debris from flying and splashing. Multiple nozzles are detachably connected to the lower surface of the gear seat 56 near the outer side of the polishing disc 59. The water tank 53 is connected to the output end of the water tank 53, which improves the protection and dust prevention of the equipment during the polishing process of the processed bolts. The water tank 53 is fixedly installed on the right surface of the housing 51. During the polishing process, the water in the water tank 53 is sprayed out from the gear seat 56 through the pipe, which cools down the polished bolt area and prevents the polishing disc 59 from being damaged by high temperature due to rotating grinding. The motor 54 is fixedly installed on the lower surface of the water tank 53. The output shaft of the motor 54 rotates to drive the rotating column 52 to rotate, which in turn causes the gear disc 55 to rotate and drive the gear seat 56 to rotate, thereby spraying water. The output shaft of the motor 54 is fixedly installed with the gear disc 55 through the rotating column 52. The teeth on the outer wall of the gear disc 55 mesh with the teeth on the outer wall of the gear seat 56. Under the centrifugal force of the rotating protective strip 57 and support plate 58, a protective channel is formed to prevent water and debris from flying into the air, further improving the polishing effect of the equipment.

[0026] Reference Figures 2-4Water flows downwards under gravity, and the filter plate 61 separates the solid and liquid debris generated by the polishing bolts during the polishing process. The separated filtrate enters the collection chamber 3 for collection. The output pipe of the purifier 7 is connected to the input end of the water tank 53. The purifier 7 purifies the filtrate, allowing the purified cutting fluid to be reintroduced into the water tank 53, forming a circulation loop for the cutting fluid and improving the resource utilization rate of the cutting fluid. The filter assembly 6 includes a filter plate 61, which is fixedly installed on the upper surface of the positioning groove 66 by fixing bolts 62. It separates large debris from the polishing mixture, improving the convenience of subsequent collection of bolt debris by workers. The left and right ends of the filter plate 61 are detachably connected to fixing bolts 62. Two sets of mounting grooves 63 are provided on the lower surface of the filter plate 61. The filter plate 61 and the filter screen 65 can be separated by the mounting grooves 63 and the mounting blocks 64, which improves the convenience of equipment maintenance. The mounting blocks 64 are slidably connected to the grooves of the mounting grooves 63. The mixed liquid enters the filter screen 65 through the holes of the filter plate 61. The filter screen 65 is fixedly connected to the lower surface of the mounting blocks 64. The front and rear surfaces of the filter screen 65 are both set as semi-circular arcs. The top corner of the outer wall of the filter screen 65 is set as a rounded corner structure. The arc design of the filter screen 65 facilitates the separation of fine debris in the polishing mixture. A positioning groove 66 is provided at the center of the upper surface of the processing table 1. The filter assembly 6 is assembled by the fixing bolts 62 and the positioning groove 66, which improves the convenience of equipment installation and disassembly and enriches the functionality of the equipment.

[0027] Working principle: After the bolt is positioned and fixed by the fixing components in the comparison document, the bolt is adjusted to the designated processing area of ​​the polishing disc 59. The polishing component 5 is then started. The polishing disc 59 in the housing 51 polishes the outer wall of the bolt. During the polishing process, water in the water tank 53 is sprayed out from the gear seat 56 through the pipe, which cools the polished area of ​​the bolt and prevents the polishing disc 59 from being damaged by high temperature due to rotation and grinding. In addition, the debris generated during the polishing process is sprayed with water to suppress the flying debris and prevent the debris from flying and splashing. This improves the protection and dust prevention of the equipment during the bolt polishing process. The output shaft of the motor 54 rotates, which drives the rotating column 52 to rotate, causing the gear disc 55 to rotate and drive the gear seat 56 to rotate. The sprayed water flow forms a protective channel under the centrifugal force of the rotating protective strip 57 and support plate 58, preventing water and debris from flying into the air and further improving the polishing effect of the equipment.

[0028] Water flows downwards under the influence of gravity, and through the filter plate 61, it separates the solid and liquid debris generated by the processed bolts during the polishing process. This separation of large debris from the polishing mixture improves the convenience of subsequent collection of bolt debris by workers. The mixture passing through the holes of the filter plate 61 enters the filter screen 65. The arc-shaped design of the filter screen 65 facilitates the separation of fine debris in the polishing mixture. The filter plate 61 and the filter screen 65 can be separated by the mounting groove 63 and the mounting block 64, improving the convenience of equipment maintenance. The filter assembly 6 can be assembled by the fixing bolts 62 and the positioning groove 66, improving the convenience of equipment installation and disassembly and enriching the functionality of the equipment.

[0029] 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.
