Dismounting device for bushing

Abstract

The invention discloses a dismounting device for a bushing. The bushing is fixedly arranged in a pipe seat and is characterized by comprising a supporting seat, wherein a concave part is formed in the end face, within the contact region with the pipe seat, on the supporting seat; the diameter of the concave part is matched with the outer diameter of the bushing; the concave part and the bushing are corresponding in positions; a pressure bar is arranged on the other end, far away from the supporting seat, of the pipe seat; the outer diameter of the pressure bar is smaller than the pipe hole diameter of the pipe seat and the bar end of the pressure bar is abutted against the end part of the bushing; and a power mechanism drives the supporting seat and the pressure bar to oppositely move. When the dismounting device is used, one end of the pipe seat and one end where the concave part of the supporting seat is are correspondingly arranged; the other end of the pipe seat and the bar end of the pressure bar are correspondingly arranged; and the supporting seat and the bushing are coaxially arranged, the pressure bar and the supporting seat are driven by the power mechanism to form opposite motion, so that the bushing can be effectively dismounted from the pipe hole of the pipe seat.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a bushing dismounting device. Background technique [0002] Shock-absorbing bushings are commonly used elastic parts connecting vehicle control arms and sub-frames or body parts. They have the characteristics of alleviating the impact caused by uneven roads, vehicle acceleration and braking, and ensuring passenger comfort and handling stability. like figure 1 Shown is the structure of a common bushing, which includes a metal inner tube 1, a rubber tube 2, and a metal outer tube 3 whose shaft cores overlap and whose diameters increase sequentially. The rubber tube 2, the metal inner tube 1, and the metal outer tube 3 Vulcanized into one body, when in use, press the bush as a whole into the tube hole of the tube seat such as the control arm body, and the metal outer tube 3 of the bush is in interference fit with the tube hole, so that the connecting rod passes thro...

AI Technical Summary

Problems solved by technology

[0003] Since the bushing is in a state of repeated deformation during the operation of the vehicle, the rubber tube 2 is easily damaged, and the shock absorption capacity of the bushing is greatly reduced. Therefore, it is necessary to remove the damaged bushing from the pipe hole of the pipe seat for replacement in time

At present, enterprises mainly use violent hammering, burning rubber tubes 2 or special presses to disassemble the bushings. Among them, violent hammering and burning rubber tubes 2 will undoubtedly cause irreversible damage to the state of the control arm. Not only the cost is high, but also the portability and popularity are poor
