Description

Technical Field

[0001] The present application relates to the technical field of caliper bushing press-fitting, and in particular to a caliper bushing press-fitting device. Background Art

[0002] Disc brakes are braking devices that use stationary brake pads to clamp brake discs that rotate with the wheels. The relative movement of the two generates friction, thereby reducing the rotation speed of the wheels.

[0003] The bushing is a friction brake material installed on the back plate of the brake pad. It is part of the caliper processing and installation. In the related art, when installing the bushing on the caliper, the bushing is manually placed on the caliper, and it is limited by the clamping parts, and then press-fitted.

[0042] In some examples, a surface of the fixing plate 350 contacting the caliper body 400 may be configured to be in an arc shape, so as to ensure that it can fit caliper bodies 400 of different specifications and ensure the tightness of its connection with the caliper body 400.

[0043] The caliper body 400 is evenly arranged at the inner upper end of the base body 100, and an adjustment assembly 500 is arranged inside the base body 100.

The feeding gear 610 can be meshed with the linkage gear 250. When the linkage gear 250 rotates, the feeding gear 610 rotates accordingly, so that the device can complete the feeding of the caliper body 400, and it can also facilitate the subsequent feeding gear 610 to clamp and feed the bushing body 800 through the clamping assembly 700.

[0045] The outer surface of the main body plate 240 is provided with a linkage gear 250, which is meshed with the feed gear 610, and the gear ratio of the linkage gear 250 to the feed gear 610 is 3:2.

The press-fitting assembly 130 can perform press-fitting processing when the bushing body 800 and the caliper body 400 maintain a straight line, so that the bushing body 800 is accurately assembled on the caliper body 400.

[0046] In some examples, the first rotary joint 330 and the second rotary joint 620 are both LX88M-11581CK joints, which can supply air to the main plate 240 and the feeding gear 610 during their rotation.

When the high-pressure gas enters the clamping chute 710, the connecting plate 720 can be pushed outward. The rack body 740 on the outside of the connecting plate 720 is meshed with the clamping gear 750. When the rack body 740 slides outward, the clamping gear 750 expands the clamping plate 760 to both sides.
