[0023] Reference Figure 1-4 A power fitting grinding device includes a grinding frame 1. Multiple support legs are fixedly connected to the bottom of the grinding frame 1 to stably support the entire device. A switch door 2 is provided on the side wall of the grinding frame 1 to facilitate the operator placing or removing the power fittings to be ground. A servo motor 3 is fixedly connected to the outer wall of the grinding frame 1. A threaded rod 4 is fixedly connected to the output end of the servo motor 3. The threaded rod 4 passes through the side wall of the grinding frame 1 and is fixedly connected to a disc 18. A threaded block 5 is connected to the threaded rod 4 inside the grinding frame 1. The top of the threaded block 5 is slidably connected to the top of the grinding frame 1. A grinding head 6 is connected to the bottom of the threaded block 5, and abrasive is installed on the grinding head 6 for actual grinding work. The threaded rod 4 on the outer side of the grinding frame 1 is connected to a transmission shaft 8 via a transmission mechanism. The transmission shaft 8 passes through the side wall of the grinding frame 1 and is fixed to a first clamping plate 10. An adjustment mechanism is provided on the side wall of the grinding frame 1. A spray mechanism is provided at the bottom of the grinding frame 1 for water cooling during the grinding process. The spray mechanism is connected to the disc 18 via a drive mechanism.

[0024] The threaded block 5 has a threaded opening, the inner wall of the threaded opening has an internal thread, and the outer wall of the threaded rod 4 has an external thread. The inner wall of the threaded opening and the outer wall of the threaded rod 4 are threadedly connected. This design allows the grinding head 6 to move up and down under the drive of the threaded block 5 to perform grinding operations at different heights.

[0025] The adjustment mechanism includes an adjustment port on the outer wall of the grinding frame 1. An adjustment rod 9 is threadedly connected to the inner wall of the adjustment port. A handle 12 is fixedly connected to the left end of the adjustment rod 9. A second clamping plate 11 is rotatably connected to the right end of the adjustment rod 9. The second clamping plate 11 and the first clamping plate 10 are located on the same horizontal line and work together to clamp the hardware. By rotating the handle 12, the adjustment rod 9 can move back and forth in the adjustment port, thereby changing the position of the second clamping plate 11 and achieving precise clamping of the hardware.

[0026] The transmission mechanism includes a first transmission belt fixedly sleeved on the outer wall of the threaded rod 4, and a second transmission belt fixedly sleeved on the outer wall of the transmission shaft 8. The first transmission belt and the second transmission belt are connected by transmission belt 7. The self-centering clamping of the hardware is achieved through rotational motion, thereby improving the grinding accuracy.

[0027] The spraying mechanism includes a spraying frame 13 fixedly connected to the bottom of the grinding frame 1. A piston plate 14 is slidably connected to the inner side wall of the spraying frame 13. Multiple spray nozzles 15 are provided on the top of the spraying frame 13. A piston rod 16 is fixedly connected to the bottom of the piston plate 14. The bottom of the piston rod 16 passes through the bottom of the grinding frame 1 and the bottom of the spraying frame 13. When the spraying mechanism needs to be activated, the piston plate 14 moves downward, forcing the liquid in the spraying frame 13 to be sprayed out through the spray nozzles 15, covering the grinding area and achieving the purpose of cooling.

[0028] The driving mechanism includes a driving plate 17 fixedly connected to the bottom of the piston rod 16, and a vertically arranged driving rod 19 fixedly connected to the top of the driving plate 17. The disc 18 and the driving rod 19 are connected by a connecting rod 20.

[0029] The outer walls of the disc 18 and the driving rod 19 are fixedly connected with pins. The connecting rod 20 has pin holes at both ends. The two pin holes are respectively rotatably sleeved on the outer walls of the two pins. When the disc 18 rotates with the threaded rod 4, the connecting rod 20 drives the piston rod 16 to move up and down through the pin connection, thereby starting the spraying mechanism.

[0030] The specific working principle of this utility model is as follows:

[0031] In the initial state, first open the switch door 2 on the side wall of the grinding frame 1, put the power fitting to be ground into the grinding frame 1, and drive the second clamping plate 11 to move by rotating the handle 12, so that the first clamping plate 10 and the second clamping plate 11 fix the fitting. After fixing, close the switch door 2. Next, start the servo motor 3. The output end of the servo motor 3 drives the threaded rod 4 to rotate. Since the threaded rod 4 and the threaded block 5 are connected by a threaded opening, as the threaded rod 4 rotates, the threaded block 5 will move left and right along the threaded rod 4 under the action of the thread. The top of the threaded block 5 is slidably connected to the inner top of the grinding frame 1 to ensure the stable movement of the threaded block 5. When it contacts the surface of the power fitting, the grinding operation begins.

[0032] At the same time, the first transmission belt on the threaded rod 4 is connected to the second transmission belt on the transmission shaft 8 through the transmission belt 7, so that the transmission shaft 8 rotates together with the threaded rod 4. The transmission shaft 8 passes through the side wall of the grinding frame 1 and is fixedly connected to the first clamping plate 10, so that the hardware can rotate synchronously with the rotation of the transmission shaft 8, thereby ensuring that the fixed power hardware can be evenly subjected to the force of the grinding head 6 during the grinding process, improving grinding efficiency and quality.

[0033] When the disc 18 rotates with the threaded rod 4, the top of the driving rod 19 will convert the rotational motion of the disc 18 into the linear reciprocating motion of the piston rod 16 through the swing of the connecting rod 20. This will drive the piston plate 14 to move up and down in the spray frame 13. The spray frame 13 is filled with liquid cleaning agent. Through the up and down movement of the piston plate 14 and the piston rod 16, the liquid will be pumped into the spray frame 13 and evenly sprayed onto the polishing area through multiple spray nozzles 15 to achieve continuous spraying. The cooperation and synergy between the various components enable the entire power fitting polishing device to complete the polishing task of power fittings efficiently and stably.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
