Description

Technical Field

[0001] The utility model belongs to the technical field of bushing processing, in particular to a bushing edge removing device. Background Art

[0002] A bushing is a matching part outside a mechanical part, which mainly plays the role of sealing and wear protection. As a ring-shaped liner, bushings are widely used in various mechanical equipment. Bushings have high flexibility in use and can play an important role in many aspects. It is one of the key components for protecting equipment, which can effectively reduce the wear, vibration and noise of equipment, and has an anti-corrosion effect. In addition, the use of bushings can also facilitate the maintenance of mechanical equipment, simplify the structure and manufacturing process of equipment, and increase the service life of equipment.

[0003] In contrast, a Chinese patent with announcement number CN115056399A discloses a debonding device for automobile bushing production, including a base plate and support columns, the lower surface of the base plate is symmetrically fixedly connected with the support columns, the upper surface of the base plate is provided with a groove, the surface of the groove is slidably connected with a movable plate, the upper surface of the movable plate is provided with a rectangular hole, the upper surface of the movable plate is rotatably installed with a clamping and positioning device located next to the rectangular hole, the clamping and positioning device is fixedly connected to the base plate, the upper surface of the movable plate is symmetrically fixedly connected with vertical columns near the edge, the four vertical columns are fixedly connected with a top plate at one end away from the movable plate, the lower surface of the top plate is fixedly connected with a debonding mechanism, and the four vertical columns are all slidably connected to the debonding mechanism.
