[0007] Preferably, a protective ring is movably inserted into the upper part of the circular slot.

[0008] Preferably, the sanding paper can be replaced with a polishing cloth.

[0009] Preferably, the bottom surface of the circular slot has an inclined angle.

[0010] Preferably, the drain outlet has an inclined angle. Beneficial effects

[0011] This invention provides a grinding device for parts processing. The device features a structure designed for convenient grinding, where grinding paper is fixedly clamped onto a support plate. Coolant is sprayed onto the grinding paper through an inlet. A motor is activated to rotate the grinding paper. The part is held in hand and brought into contact with the surface of the grinding paper for grinding. The grinding paper can be replaced with a polishing cloth for polishing. This device allows for hand-held grinding of parts, offering greater flexibility, quick grinding paper replacement, and easy transition to the polishing stage, making it highly practical.

[0014] 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.

[0015] Please see Figure 1This utility model provides a technical solution: a grinding device for parts processing, including a base 1. The upper wall of the base 1 has a drain port 8 and a circular slot 7. The drain port 8 connects the circular slot 7 to the side wall of the base 1. A motor 2 is installed inside the base 1. The drive end of the motor 2 has a rotating shaft 3, which is rotatably connected to the bottom surface of the circular slot 7. A support plate 4 is provided on the upper wall of the rotating shaft 3. Grinding paper 5 can be placed on the upper wall of the support plate 4. The base 1 is threaded with an annular sleeve 6. A water tank 10 is provided on the side wall of the base 1. A water pump 11 is provided at the bottom of the water tank 10. A connecting pipe 12 is connected to the output end of the water pump 11. A rotating block 13 is rotatably connected to the upper end of the water tank 10. A water outlet pipe 14 is connected to the side wall of the rotating block 13. A valve 15 is provided on the water outlet pipe 14. The connecting pipe 12 is inserted into the rotating block 13 and communicates with the water outlet pipe 14. A water inlet 16 is provided at the upper part of one side wall of the water tank 10 and a water outlet 17 is provided at the lower part.

[0016] In this embodiment, a protective ring 9 is movably inserted into the upper part of the circular slot 7.

[0017] In this embodiment, the sanding paper 5 can be replaced with a polishing cloth.

[0018] In this embodiment, the bottom surface of the circular slot 7 is further configured to have an inclined angle.

[0019] In this embodiment, the drain outlet 8 is further configured to have an inclined angle.

[0020] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0021] Example: Place the polishing paper 5 on the support plate 4, and connect it to the annular sleeve 6 via a threaded connection, so that the polishing paper 5 is positioned between the support plate 4 and the annular sleeve 6 and is clamped and fixed. Place coolant into the water tank 10 through the inlet 16, start the water pump 11 and valve 15, and the coolant enters the outlet pipe 14 through the connecting pipe 12, finally spraying onto the polishing paper 5. Turn on the motor 2 to drive the rotating shaft 3 to rotate, which in turn drives the support plate 4 to rotate, and the support plate 4 to rotate the polishing paper 5. Hold the part in contact with the surface of the polishing paper 5 and polish the part. This can be repeated multiple times. Afterwards, close the valve 15 and the motor 2, and unscrew the annular sleeve 6 to remove it. The polishing paper 5 can be replaced with a polishing cloth. Similarly, after fixing the annular sleeve 6, adjust the polishing fluid to polish the part. Impurities generated during polishing will mix with the coolant in the circular groove 7 and finally drain out from the drain port 8 along the bottom slope of the circular groove 7.
