Problems solved by technology

This process was completed before by adjusting the position, and the bushing was constantly crushed when the pin was installed; the expansion of the bushing size could not be satisfied, and the parts were not in the original position after reaming, and the employees kept straightening the parts; the torque requirements could not be met, and rework steps were added Realized, this mode requires a large investment cost and low efficiency

Embodiment 1

[0025] A device for press-fitting bushings, the structure of which is as follows figure 1 As shown, it includes a circular turntable 1, three worktables 2 evenly arranged on the circumference of the turntable 1, and a pre-pressing unit 4 and a platen unit 5 fixedly arranged next to the turntable 1 in sequence. The worktable 2 is provided with circular positioning pins. 3. When installing, the original bushing is installed in the mounting hole of the parts to be processed, and then placed on the positioning pin 3 of the loading station, and then the turntable 1 rotates 120° each time, and the parts to be processed are sent to the pre-pressing unit in turn 4 and platen unit 5 for processing.

[0026] The structure of the bushing original is as follows figure 2 As shown, it is T-shaped, including an annular bottom plate 6, and a cylindrical bushing part 7 integrally arranged on the upper surface of the bottom plate 6. The bushing part 7 is connected with the inner ring of the b...

Abstract

The invention relates to a device for pressing a bushing. The device comprises a circular turntable, a plurality of workbenches uniformly arranged on the circumference of the turntable, a prepressingunit and a pressing plate unit sequentially arranged beside the turntable. Circular positioning pins are arranged on the workbenches, and during installation, the bushing original is installed in themounting hole of a part to be processed, and then placed on the positioning pins. Compared with the prior art, the device has high production efficiency and good product quality.

Description

technical field [0001] The invention relates to the technical field of automobile parts production, in particular to a device for press-fitting bushings. Background technique [0002] Door hinges and car door assemblies are mass-produced, not only because of the large production volume, but also because of the variety of accessories that make up them, and the assembly process is also very particular, from pre-pressing bushings, pressing bushes, pin shaft gaskets, etc. , riveting, etc., these steps are indispensable, and require very high tightness. [0003] As far as the step of processing the pre-compressed bush and the pressed bush is concerned, in addition to the position, the hinge also needs to control the torsion. This process was completed before by adjusting the position, and the bushing was constantly crushed when the pin was installed; the expansion of the bushing size could not be satisfied, and the parts were not in the original position after reaming, and the e...
