Description

Technical Field

[0001] The invention belongs to the field of automated production equipment, and in particular relates to a stabilizer bar bushing automatic grinding and gluing machine. Background Art

[0002] The automobile stabilizer bar is an auxiliary elastic element in the automobile suspension. Its two ends are connected to the suspension, and the middle part is fixed to the subframe through a clamp and a bushing, so that the suspension, subframe, and stabilizer bar are connected as a whole to prevent the vehicle body from excessive lateral tilt when turning and keep the vehicle body balanced as much as possible. At this time, the bushing will be subjected to a certain amount of stress and torsional friction from the stabilizer bar. Due to the long-term repeated stress and torsional friction, the traditional fixing method bushing will cause relative displacement and wear with the stabilizer bar, which will generate loud noise and reduce the service life;

[0003] In order to solve the problem of torsional friction noise, some high-end cars use more expensive vulcanized bonded stabilizer bar bushings to solve the problem of friction noise caused by relative displacement. However, due to the production process, the surface of the newly manufactured rubber bushings will be very smooth and have a layer of wax. If they are directly coated with glue and vulcanized, it will affect the strength of the bond and even cause debonding. Therefore, the inner hole of the bushing needs to be dewaxed before vulcanization bonding;

[0004] There are two traditional ways to remove wax from stabilizer bar bushings. One is ultrasonic cleaning. Although this method can remove wax from the surface of the bushing, the effect of applying glue and vulcanization bonding on the smooth inner hole surface is not very ideal. The other method is to remove the wax from the inner hole of the bushing by grinding, and it can also increase the roughness of the inner hole, which can achieve an ideal bonding effect. However, the main operation method at this stage is that workers manually grind the inner hole of the stabilizer bar bushing one by one with an emery cloth grinding head, and then apply glue with a brush. This operation method has several disadvantages: First, the production efficiency of manual operation is low; second, manual grinding depends entirely on the worker's senses, and it is impossible to guarantee a uniform grinding measurement; third, manual glue brushing cannot guarantee the uniformity and uniformity of the glue amount; fourth, the dust generated by grinding and the gas emitted by the glue solvent during glue application will cause harm to the human body. Therefore, an automated stabilizer bar bushing grinding and glue coating machine is urgently needed. Summary of the invention
