Description

Technical Field

[0001] This application relates to the technical field of rust removal of mechanical parts, and particularly relates to a rust removal device for mechanical parts. Background Art

[0002] Common rust removal methods include chemical rust removal, electro-chemical rust removal, sandblasting rust removal, manual rust removal, barrel finishing, etc. Chemical rust removal, also known as etching or pickling, uses an acidic solution (or alkaline solution) to react with the rust layer on the metal surface to dissolve and peel off the rust layer.

[0003] However, in practical applications, when most existing tubular mechanical parts are subjected to surface rust removal, the pickling immersion method is usually used. However, the static immersion rust removal method requires a relatively long time for the reaction, which will lead to a relatively low rust removal reaction efficiency and cause a certain waste of time.

[0004] Therefore, those skilled in the art have provided a rust removal device for mechanical parts to solve the problems raised in the above background art. Utility Model Content

[0005] In order to solve the problem that the static immersion rust removal method in the above background art requires a relatively long time for the reaction, which will lead to a relatively low rust removal reaction efficiency and cause a certain waste of time, this application provides a rust removal device for mechanical parts.

[0007] Preferably, a plurality of brush rods are rotatably connected to the bottom inner wall of the processing cover, and bristles on the plurality of brush rods are all in contact with the surface of the placed tubular mechanical parts.

[0009] Preferably, inner walls of the four limit sleeves are all slidably connected with limit rods, and blocks are fixedly connected to the top ends of the four limit rods.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. By setting a supporting plate, placing the tubular mechanical part on the top side of the supporting plate, the output shaft of the motor drives the supporting plate to rotate, and the supporting plate drives the placed tubular mechanical part to rotate. The tubular mechanical part can accelerate the reaction speed with the hydrochloric acid solution in the rotating state, thereby accelerating the rust removal efficiency and saving time. The resilience of the spring drives the limiting sleeve to contact the inner wall of the tubular mechanical part. At this time, the four limiting sleeves cooperate with each other to limit the placed tubular mechanical part, thus preventing the tubular mechanical part from shifting during rotation.

[0012] 2. By setting a brush rod, when the supporting plate drives the placed tubular mechanical part to rotate, it forms friction with the bristles on the brush rod, thereby significantly improving the rust removal efficiency. Description of the Drawings

Hydrochloric acid solution is filled in the processing cover 1. By providing the support plate 3, a tubular mechanical part is placed on the top side of the support plate 3. The output shaft of the motor 2 drives the support plate 3 to rotate. The support plate 3 drives the placed tubular mechanical part to rotate. The tubular mechanical part can accelerate the reaction speed with the hydrochloric acid solution in the rotating state, thereby accelerating the rust removal efficiency and saving time. The resilience of the spring 5 drives the limiting sleeve 4 to contact the inner wall of the tubular mechanical part. At this time, the four limiting sleeves 4 cooperate with each other to limit the placed tubular mechanical part, thus preventing the tubular mechanical part from shifting during rotation.

[0019] In this application, a plurality of brush rods 6 are rotatably connected to the inner wall of the bottom side of the processing cover 1. The bristles on the plurality of brush rods 6 all contact the surface of the placed tubular mechanical part. By providing the brush rods 6, when the support plate 3 drives the placed tubular mechanical part to rotate, friction is formed with the bristles on the brush rods 6, thereby significantly improving the rust removal efficiency.

[0020] In this application, a toothed ring 7 is fixedly connected to the bottom side of the support plate 3. A gear 8 is fixedly sleeved on the outer side of each of the plurality of brush rods 6. The plurality of gears 8 are all meshed with the toothed ring 7. By providing the toothed ring 7 and the gears 8, the support plate 3 drives the toothed ring 7 to rotate.

When the tubular mechanical part is in a rotating state, the reaction speed with the hydrochloric acid solution can be accelerated, thereby accelerating the rust removal efficiency and saving time.
