Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a polishing device for a yoke forging of an automobile steering gear. Background Art

[0002] The automobile steering gear yoke forging is one of the important components in the automobile steering system, which is used to connect the steering rod and the steering gear to achieve the steering action. It is usually made of high-strength steel through a forging process, with high strength and wear resistance to ensure the reliability and safety of the steering system. The main function of the yoke forging is to transfer the steering force to the steering gear or rack when the driver operates the steering wheel, and change the direction of the vehicle through the movement of the steering gear or rack. It needs to withstand the torque generated by the driver when operating the steering wheel, and transfer this torque to other parts of the steering system to ensure that the vehicle can turn accurately and smoothly.

[0003] Since yoke forgings are usually designed into specific shapes and sizes, it is difficult for general polishing devices to take care of every part of the yoke forgings, so a magnetic polishing machine is used to polish the yoke forgings. The polishing barrel is easily shaken by the rotating stainless steel needle polishing material inside during polishing. An unstable polishing barrel may have safety hazards. For example, the barrel body may be detached from the support or tilted, which may cause the polishing material to overflow or the equipment to tip over, causing accidental injury or loss. The shaking polishing barrel may also cause the stainless steel needle and yoke forging inside to fly out, affecting the polishing effect of the yoke forging. In view of the above problems, a polishing device for automobile steering gear yoke forgings is proposed to solve them. Utility Model Content
