[0002] Rust removal devices for parts processing are devices used to remove rust from the surface of parts. During the parts processing process, rust may appear on the surface of metal parts, which may affect the quality and performance of the parts. Rust removal devices usually use physical or chemical methods to remove rust, such as mechanical grinding, sandblasting, chemical dissolution, etc. These devices can help maintain the smoothness and flatness of the surface of the parts, ensuring that the parts have good performance in subsequent processing and use.

[0003] At present, grinding the surface of parts by grinding discs is a commonly used rust removal method. A mechanical parts grinding device is disclosed in the Chinese utility model patent with publication number CN220408203U. Its clamping rod clamps the mechanical parts from the side under the linkage of the push frame, corrects the position of the mechanical parts, and ensures that they will not deflect during the grinding process. The processing accuracy is high, which solves the problem of manual clamping.

[0004] In the process of grinding and rust removal on the circumferential surface of a columnar part, the circumferential surface of the columnar part needs to be brought into contact with a high-speed rotating grinding disc, and the above-mentioned equipment clamps the arc-shaped surface of the part by clamping rods on both sides, which makes it easy for the part to deviate when being ground. Therefore, it is necessary to design a rust removal device for part processing to solve the above-mentioned problem. Utility Model Content

[0021] See also Figure 1-4 The utility model provides a rust removal device for parts processing, comprising a base 1, a grinding disc 2 is provided on the top of the base 1, an L-shaped support 3 which can be moved left and right is arranged on one side of the top of the base 1, a placement disc 4 for supporting columnar parts is rotatably connected to the L-shaped support 3, a liftable mounting block 5 is arranged on the top of the L-shaped support 3, and a rotatable pressing plate 6 is arranged on the bottom of the mounting block 5. Through such a design, the columnar parts that need to be rusted on the circumferential surface can be placed on the placement disc 4, and the pressing plate 6 can be driven to descend synchronously by the descending of the mounting block 5 itself, so that the pressing plate 6 can press the columnar parts on the placement disc 4, and then the movement of the L-shaped support 3 can drive the parts to move toward the direction of the grinding disc 2, so that the grinding disc 2 can contact the surface of the parts and perform grinding and rust removal, and at this time, the pressing plate 6 can also rotate to drive the columnar parts to rotate, so as to achieve the effect of rust removal on the columnar parts quickly and efficiently.

[0023] At the same time, a servo motor 8 with an output shaft facing downward is fixedly installed at the bottom of the mounting block 5. The end of the output shaft of the servo motor 8 is fixedly connected to the top of the pressure plate 6. When the output shaft of the mounting block 5 rotates, the pressure plate 6 can be driven to rotate synchronously. In this way, when the pressure plate 6 presses the columnar parts, it can drive the parts to rotate synchronously through its own rotation.

[0024] The specific connection method between the L-shaped support 3 and the base 1 is as follows: four symmetrical fixed blocks 9 are fixedly connected to the top of the base 1, a guide rod 10 is fixedly connected between every two left-right symmetrical fixed blocks 9, and the two sides of the L-shaped support 3 are respectively slidably sleeved on the two guide rods 10, so that the L-shaped support 3 can form a left-right snap-fit ​​sliding connection on the top of the base 1.
