Description

Technical Field

[0001] The present application relates to the field of induction heating equipment, and in particular to an automatic assembly production line for stabilizer bar bushings. Background Art

[0002] The stabilizer bar is an auxiliary elastic element in the automobile suspension. Its function is to prevent the vehicle body from excessive lateral roll when turning and to keep the vehicle body balanced as much as possible. The two ends of the stabilizer bar are fixed to the left and right suspensions respectively through the stabilizer bar connecting rods. When the vehicle body only moves vertically, the deformation of the suspensions on both sides is the same, and the stabilizer bar does not work; when the vehicle body rolls, the suspensions on both sides jump inconsistently, the stabilizer bar twists, and the elastic force of the bar body becomes a resistance to continued roll, playing a role in lateral stability.

[0003] The stabilizer bar is provided with a U-shaped clamp, which is sleeved on the rod of the stabilizer bar, and the opening of the clamp is fixedly connected to the vehicle body. Generally, a bushing is provided between the clamp and the rod to enhance the tightness of the connection between the clamp and the rod. However, the existing bushing is easy to move relative to the rod when the vehicle rolls, which aggravates the wear of the bushing and also produces a large noise.

[0004] To solve the problem of the bushing moving relative to the stabilizer bar, the current process is to first clean the bar, then press the two halves of the bushing coated with glue onto the stabilizer bar and maintain the pressure, and then induction heat the stabilizer bar to make the glue effective. Most of the steps in the above process are completed manually with equipment, but since the bushing needs to be pressurized during the induction heating process, the high temperature makes it impossible to maintain the pressure manually, so an automated production line is urgently needed. Summary of the invention

[0005] In order to solve the problem that it is impossible to manually maintain the pressure of the bushing under high temperature, the present application provides an automatic assembly production line for stabilizer bar bushings.
