Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to an oil seal press-fitting device. Background Technology

[0002] The core task of the oil seal press-fitting device in the brake wheel hub assembly is to press the inner / outer oil seals of the brake wheel hub assembly into the designated sealing grooves on the outer ring of the wheel hub or bearing in a precise, reliable, non-destructive, and consistent manner. The oil seal is typically a metal skeleton covered with rubber and has a precision-formed sealing lip. It needs to form an interference fit with the sealing groove on the outer ring of the wheel hub or bearing to ensure a static seal effect. Since the most critical aspect of the oil seal is the protection of the sealing lip, any scratches, deformation, or flanges will lead to seal failure. Therefore, automated oil seal press-fitting equipment is often used to ensure that the sealing lip can smoothly slide across the mating surface without damage, and to ensure that the pressing depth, angle, and force of each oil seal are highly consistent.

[0003] However, in actual use, existing automated oil seal pressing devices still have the problem of pressing off the seal or workpiece due to misalignment or misalignment. Therefore, an oil seal pressing device is proposed as a further improvement. Utility Model Content

The mounting bracket 33 is mainly used to support the entire oil seal pressing device, while the support leg 34 is mainly used to adjust the level of the mounting bracket 33.

[0094] The working principle of this utility model is as follows: When in use, the brake hub assembly is first fixed on the positioning plate 2 as a workpiece; and the positioning plate 2 and the brake hub assembly are determined to be in a horizontal state by the first detection device 81.

[0095] Subsequently, the gear 95 is driven to rotate by the gear motor 93 and fixed by the rack 94. The rack 94 meshes with the gear 95, and the gear 95 will rotate along the rack 94. The gear motor 93, which controls the rotation of the gear 95, slides along the rack 94 with the gear 95.

[0096] Then, under the action of the integrated geared motor 93, geared motor mounting bracket 92 and motor mounting plate 91, the motor slides along the rack 94 or the linear rail 4. The second detection device 82 determines that the whole unit has moved below the pressure head 1, that is, the positioning plate 2 and the brake hub assembly are below the pressure head 1.

[0097] When the entire assembly moves below the pressure head 1, the pressure head 1 moves above the brake wheel hub assembly under the action of the cylinder 52, pressing the oil seal into the inner cavity of the brake wheel hub, thus completing the oil seal pressing operation.
