Description

Technical Field

[0001] The utility model belongs to the technical field of bushing disassembly, and more specifically, particularly relates to a bushing disassembly device. Background Art

[0002] Aircraft bushings are indispensable anti-friction and wear-resistant parts in the movable connection assembly of aircraft components. The function of the bushing is to ensure the tightness between the two connecting parts. The effect and purpose are similar to the washers in household faucets. When the bushing is worn to a certain extent, it needs to be replaced. Since the inner wall and outer surface of the bushing are relatively smooth, the traditional disassembly method is usually to use a screwdriver or other equipment to expand the gap between the bushing and the part. After the connection between the bushing and the part is loosened, use pliers to pull the bushing out of the part. This method is time-consuming and labor-intensive, and using a screwdriver to pry the bushing is likely to damage the parts connected to the bushing. Utility Model Content

The rubber material has a high friction coefficient. When the clamping jaws 5 clamp the bushing, the setting of the rubber pads 18 can increase the friction between the bushing and the clamping jaws 5, and can provide additional supporting force, further strengthen the fit between the clamping jaws 5 and the bushing, and improve the stability and safety of the device. Multiple groups of rubber pads 18 and multiple groups of clamping jaws 5 are each provided with through holes 14, one end of multiple groups of drill rods 11 respectively passes through multiple groups of through holes 14, both sides of multiple groups of clamping jaws 5 are provided with slide grooves 17, multiple groups of support plates 13 are respectively clamped in multiple groups of slide grooves 17, so that the motor 10 can move in the clamping jaws 5, the tops of multiple groups of slide grooves 17 are each provided with through grooves 15, and springs 9 are clamped between multiple groups of slide grooves 17 and multiple groups of support plates 13, and one end of multiple groups of clamping jaws 5 is provided with fixing rods 12, and one end of multiple groups of fixing rods 12 respectively passes through multiple groups of support plates 13 and multiple groups of springs 9 and is clamped in multiple groups of clamping jaws 5.

The user can move the threaded rod 1 in the sliding block 3 by rotating the rotating wheel 2. When it is rotated to a certain extent, the threaded rod 1 will resist the parts connected to the bushing.
