Embodiment

[0020] Such as figure 1 , figure 2 The shown bearing removal device includes a workbench 1 on which a first support shaft 2 , a clamping mechanism 12 , a second support shaft 8 and a cylinder 13 are sequentially arranged from left to right. A cylinder body 3 is welded on the first support shaft 2, and the first piston 4 is fitted in the clearance of the cylinder body 3. There is a gap 301 between the cylinder body 3 and the first piston 4, and the minimum gap between the cylinder body 3 and the first piston 4 is 301 is greater than zero, such as image 3 As shown, the first piston 4 separates the cylinder body 3 from the upper chamber and the lower chamber, the lower chamber is provided with an elastic material layer 5, the elastic material layer 5 is a compressible rubber layer, and the side wall of the lower chamber is connected with an air outlet pipe 6 , the air outlet pipe 6 is sealed and communicated with a "U"-shaped pipe 7 made of glass, the bent part of the "U"-sha...

Abstract

The invention relates to the technical field of car accessory machining device, and particularly discloses a device for demounting a bearing. The device comprises a working table, the working table isprovided with a first supporting shaft, a clamping mechanism, a second supporting shaft and an air cylinder. The first supporting shaft is fixedly connected with a cylinder body, a first piston is arranged in the cylinder body, an elastic material layer and an air outlet pipe are arranged in the cylinder body, the air outlet pipe is in sealed connection with a U-shaped pipe, and an oil contamination washing agent is contained in the U-shaped pipe; a first piston rod is connected to the first piston, and a stopping block is fixedly connected to the first piston rod; the clamping mechanism comprises a strut, a clamping body, a first clamping piece and a second clamping piece; a second piston is arranged in the air cylinder, and the air cylinder is communicated with the cylinder body throughan air pipe; and a second piston rod is connected to the second piston. By means of the device, the bearing can be stably clamped, bearing stress is even in the bearing demounting process, and bearing damage is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts processing devices, and specifically discloses a device for dismounting a bearing. Background technique [0002] In recent years, with the rapid development of social economy, people's living standards have gradually improved, people's consumption of cars has also increased, and the market's demand for auto parts has also increased, and bearings are an indispensable part of auto parts. . Bearings are components that fix and reduce the friction coefficient of loads during mechanical transmission. When other parts move relative to each other on the shaft, the bearings can reduce the friction coefficient during power transmission and maintain the center position of the shaft. fixed. However, the bearing is extremely prone to deformation and damage during disassembly, which seriously affects the accuracy of the bearing and reduces the service life of the bearing. When disassembling the bearing t...
