[0002] During the production and processing of parts, polishing and grinding equipment is used to process metal or non-metal parts by polishing and grinding, so that the parts form a smooth surface, highlighting their texture and color, and facilitating people's use or viewing.

[0003] When polishing and grinding parts, it is necessary to fix the parts on the placement table of the polishing and grinding equipment, fix the parts, and then perform polishing and grinding to prevent the parts being processed from moving during the polishing and grinding process, resulting in damage to the parts. However, in existing polishing and grinding equipment, it is inconvenient to fix the parts being processed, and due to the different sizes of the parts being processed, it is not possible to effectively fix parts of different sizes. For this reason, we propose a positioning device for a full-automatic grinding machine to solve the above problems. Utility Model Content

[0022] The following will detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution for a positioning device for a full-automatic grinding machine:

[0024] A positioning device for a fully automatic grinding machine, comprising a workbench 3 and two moving plates 20. Two protective boxes 16 are fixedly installed on the upper surface of the workbench 3. The inner top wall of each protective box 16 is fixedly installed with a first bearing 26. Two second bearings 22 are fixedly embedded in the upper surface of the workbench 3. The inner rings of each group of first bearings 26 and the inner rings of the second bearings 22 are jointly fixedly installed with a screw rod 19. Threaded holes 23 and two limiting holes 24 are formed in the upper surface of each moving plate 20. The outer surface of each screw rod 19 is threadedly connected to the inner wall of the threaded hole 23. Two electric push rods 2 are fixedly installed on one side surface of the two moving plates 20 close to each other. Two strip-shaped openings 10 are formed in one side surface of the two protective boxes 16 close to each other. The output end of each electric push rod 2 passes through the strip-shaped opening 10 and extends to the outside of the protective box 16. The output end of each group of electric push rods 2 is fixedly installed with a positioning plate 15. Gaskets 5 are fixedly installed on one side surface of the two positioning plates 15 close to each other; specifically, each group of first bearings 26 and second bearings 22 jointly play a role in fixing the screw rod 19. Through the cooperation of the screw rod 19 and the moving plate 20, when each screw rod 19 rotates, it can drive the moving plate 20 to adjust the height. The output end of each group of electric push rods 2 can drive the positioning plate 15 to adjust the position, so that parts of different sizes can be quickly fixed;

[0025] In this embodiment, a limiting rod 21 is fixedly installed on the inner top wall of each protective box 16. The bottom end of each limiting rod 21 is fixedly installed with the upper surface of the workbench 3. The outer surface of each limiting rod 21 is slidably connected to the inner wall of the limiting hole 24; two chassis 1 are fixedly installed on the bottom surface of the workbench 3. A heat dissipation window 7 is fixedly embedded in the front surface of each chassis 1. A first motor 25 is fixedly installed on the inner bottom wall of each chassis 1. The output end of each first motor 25 is fixedly installed with the bottom end of the screw rod 19; specifically, through the cooperation of the limiting rod 21 and the limiting hole 24, each moving plate 20 can maintain stability when adjusting the height. Each chassis 1 plays a role in protecting the first motor 25 inside. Each first motor 25 can provide rotational power for the screw rod 19;

[0026] In this embodiment, a placement table 4 and an L-shaped frame 14 are fixedly installed on the upper surface of the workbench 3. A hydraulic push rod 12 is fixedly installed on the upper surface of the L-shaped frame 14. The output end of the hydraulic push rod 12 is fixedly installed with a second motor 13, and the output end of the second motor 13 is fixedly installed with a grinding disc 11. A vertical plate 9 is fixedly installed on the upper surface of the workbench 3, and a controller 8 is fixedly installed on the front surface of the vertical plate 9. Four support legs 17 are fixedly installed on the bottom surface of the workbench 3. Each support leg 17 is fixedly installed with a support base 18 at its bottom surface, and two mounting holes 6 are provided on the upper surface of each support base 18. Specifically, the output end of the hydraulic push rod 12 can drive the second motor 13 and the grinding disc 11 to adjust the height. The output end of the second motor 13 can drive the grinding disc 11 to rotate rapidly. Both the two first motors 25 and the second motor 13 are electrically connected to the controller 8 through wires. The staff can conveniently control the device through the controller 8. The four support legs 17 together lift the device to a certain height, and the four support bases 18 increase the contact area between the device and the ground, enabling the device to be stably placed.

[0027] Working principle: When it is necessary to firmly fix the parts above the placement table 4, the user first starts the two first motors 25 through the controller 8. The rotation of the output end of each first motor 25 drives the screw 19 to rotate. The rotation of each screw 19 drives the moving plate 20 to move up and down. The up and down movement of each moving plate 20 drives each group of electric push rods 2 to move up and down. The extension of the output end of each group of electric push rods 2 drives the positioning plate 15 to move. When both gaskets 5 are in close contact with the outer surface of the parts, the parts can be firmly fixed above the placement table 4.

[0028] It should also be noted that the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements not only includes those elements but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, commodity or device including the said element.

[0029] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
