Description

Technical Field

[0001] The utility model belongs to the field of bolt pre-processing, and in particular relates to a rust removal device used for bolt pre-processing. Background Art

[0002] Bolt: A mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which must be matched with a nut to fasten two parts with through holes. If the bolt is not used for a long time, rust will form on its metal surface, making it difficult to thread the bolt, so it is necessary to remove the rust from the bolt.

[0003] The patent application with announcement number CN220902873U discloses a rust removal device for bolt pre-processing, including: a base plate, a hydraulic press fixedly connected to the left and right sides of the top of the base plate, a cover plate fixedly connected to the top of the hydraulic press, a support seat fixedly connected to the right side of the front of the base plate, a motor fixedly connected to the top of the support seat, a gear 1 fixedly connected to the left output end of the motor, a bolt is arranged just above the cover plate, and a rust removal component is sleeved on the outer surface of the bolt. The utility model starts the motor through the rust removal component, and the gear 1 transmits the force of the motor to the gear 2. The gear 2 is driven by the force to drive the annular block and the rust removal roller to rotate, so as to achieve the effect of rust removal on the bolt. Through the gear 2, since the rust removal roller and the cylindrical block are integrated, the rust removal roller will be subjected to the pressure given by the spring, which can make the contact between the rust removal roller and the bolt closer, and improve the rust removal effect of the rust removal roller on the bolt to a certain extent.

[0004] However, the above technology has the following disadvantages when used:

[0005] The paragraph 0024 of the above-mentioned document describes that "a slide groove is provided on the front of gear 2, a central axis rod is vertically fixedly connected in the slide groove, a cylindrical block is slidably connected to the outer surface of the central axis rod, the cylindrical block is rotatably connected to the rust removal roller, a spring is fixedly connected to the top of the cylindrical block, and the top of the spring is fixedly connected to the top of the inner wall of the slide groove, the end of the cylindrical block away from the rust removal roller is in contact with the annular block, through gear 2, since the rust removal roller and the cylindrical block are integrated, the rust removal roller will be subjected to the pressure given by the spring, which can make the contact between the rust removal roller and the bolt closer, thus improving the rust removal effect of the rust removal roller on the bolt to a certain extent". Combined with the attached manual Figure 4 It can be seen that since the spring is easily deformed by the external force during processing, the rust removal roller will be displaced, which will further reduce the processing accuracy of the rust removal roller on the product.

[0006] Therefore, a rust removal device for bolt pre-processing is proposed to solve the above-mentioned drawbacks. Utility Model Content
