Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0026] By Figures 1-8The utility model provides a device box 1, the fixed platform 12 top mobile installation of device box 1 inside is equipped with electric polishing head 13, and the fixture 11 is installed to device box 1 inside, the cleaning mechanism 2 is installed to device box 1 outer wall, the cleaning mechanism 2 includes the water tank 21 fixed on device box 1 outer wall, two guide rods 22 are fixed in the inside bottom of water tank 21, the guide rod 22 passes two sliding blocks 23, and the sliding block 23 is fixed on both sides of water box 24, and one side of water box 24 is closely attached with the inner wall of water tank 21, and the lamination surface of water box 24 and water tank 21 is equipped with the round hole corresponding in vertical direction, and the round hole position of water tank 21 is higher, and the outer wall of water tank 21 is equipped with the water guide pipe 25 connected with round hole, and the outlet of water guide pipe 25 passes device box 1 and is located at polishing position, and one side of water box 24 is equipped with small cylinder 28, and small cylinder 28 slides in the inclined slot 27 of one side of square plate 26, and square plate 26 is slidably installed in water tank 21,

[0027] The screw rod one 29 is connected with one side of square plate 26, and the screw rod one 29 is rotatably installed in water tank 21, and the screw rod two 14 is rotatably connected in the fixed platform 12, and the moving block 15 is screw-connected outside the screw rod two 14, and the moving block 15 is slidably connected in the fixed platform 12, and the connecting piece of moving block 15 top passes the opening of fixed platform 12, and the connecting piece top butt-joints the base of electric polishing head 13, and the screw rod one 29 and screw rod two 14 are synchronously rotated through the drive mechanism 3 installed on one side of device box 1.

[0028] Through the design of the above-mentioned cleaning mechanism 2, when the device is used, the wire harness hardware terminal is fixed in the fixture 11 (it is the existing conventional fixture design, and no repeated description is made), then the drive mechanism 3 is started to make the screw rod one 29 and screw rod two 14 synchronous rotation, the moving block 15 drives the base of electric polishing head 13 to move, and the electric polishing head 13 is moved to the polishing position, and in the process, the screw rod one 29 also drives square plate 26 to start sliding in water tank 21, and the sliding of square plate 26 causes the relative movement between the inclined slot 27 arranged on it and the small cylinder 28 fixed on one side of water box 24, and the design of inclined slot 27 makes small cylinder 28 rise along the inclined upward channel of inclined slot 27, and then pushes water box 24 to move upwards along guide rod 22, and then the top surface of water box 24 rises above the water surface of water tank 21, as Figure 5 and Figure 6When the water tank 21 is full of water, the water tank 21 is lifted to the position shown by the point a, at which time water cannot be supplied, but because the position of the circular holes of the water tank 21 is higher, when the water box 24 is lifted to a certain height, the two circular holes are just matched, so that the water in the water tank 21 can flow out smoothly through the water guide pipe 25, the outlet of the water guide pipe 25 is located inside the equipment box 1 and directly opposite the polishing position, so the water can directly fall on the workpiece being polished. At this time, the electric polishing head 13 is started to polish, so that the linkage of the chute 27 and the small cylinder 28 is realized to automatically lift the water box 24 to expose the water level for drainage, and ensure that the water flow can accurately reach the polishing position to clean and cool the workpiece in time. The cleaning effect can effectively remove the debris generated in the polishing process to prevent the debris from accumulating on the surface of the workpiece or around the polishing tool, thereby improving the polishing accuracy and efficiency and reducing the wear of the polishing wheel. At the same time, the cooling effect can significantly reduce the high temperature generated during polishing to protect the surface of the workpiece from being burned, ensure the quality of the finished product, and prolong the service life of the polishing tool, thereby reducing the safety hazards to the operator. After polishing is completed, each part is reset, and the water box 24 is also lowered below the water level for water replenishment (note that the water in the water box 24 does not have to be used up).

[0030] In the detailed optimization design of the driving mechanism 3, when the first connecting screw 29 and the second connecting screw 14 rotate synchronously, the motor 31 is started to drive the second connecting screw 14 to rotate, synchronously, the two belt pulleys 32 rotate together through the belt 33, and then the first connecting screw 29 also rotates, that is, synchronous rotation is realized, which is very convenient.

[0031] Two pieces of sponge sheets 16 are bonded to the inner wall of the opening of the fixed table 12, and the sponge sheets 16 are bonded to the two sides of the connecting piece on the top of the moving block 15.

[0032] Further, the sponge sheet 16 can close the opening through which the connecting piece on the top of the moving block 15 slides, and try to contact the side of the connecting piece to avoid more dust from entering the inside of the fixed table 12, thereby playing a protective role.

[0033] The water outlet pipe 17 is provided at the bottom of the equipment box 1, a filter element 18 is installed at the top of the water outlet pipe 17, and a liquid level indicator 211 is installed on the side wall of the water tank 21.
