[0002] The main gear bearing assembly of automobile reducer inevitably needs to be repaired and re-pressed. At present, there is no special equipment for disassembling and repairing the main gear bearing, and the bearing is easily damaged during the disassembly process. The market generally uses press-fitting equipment, while there are fewer disassembly and repair equipment, and the equipment is not very versatile. Generally, they are dedicated machines, but the operation process of repairing, disassembling and re-pressing the main gear bearing is too complicated and the operation process is too cumbersome. In addition, during the process of repairing and re-pressing the main gear bearing, the corresponding tooling requirements for main gear bearings of different specifications are also different. When re-pressing the bearing, it is necessary to select gaskets, and the specifications of the gaskets are also different. In the past, the gaskets were placed in a box or tray, which made it easy to confuse gaskets of different specifications.

[0003] It can be seen that the existing equipment is not very versatile, there is no special main gear bearing disassembly equipment, and the bearing damage rate is high during the disassembly process; the main gear bearing press-fitting and disassembly equipment are separate, the main gear bearing disassembly process is complicated, the operation is inconvenient, the gasket is inconvenient to take, and the gasket specifications are easy to mix up. Utility Model Content

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] The utility model provides a press-fitting and rework workbench for main gear bearings of automobile reducers, comprising a hydraulic pump, a press-fitting table, a support seat, a hydraulic cylinder and a tooling base; the hydraulic pump is fixedly arranged at the lower part of the press-fitting table, and the tooling base is fixedly placed on the table surface of the press-fitting table through positioning pins; the bottom end of the support seat is fixed on the table surface of the press-fitting table, and the top end thereof extends to the top of the tooling base, the fixed end of the hydraulic cylinder is fixedly arranged on the top end of the support seat, and the movable end of the hydraulic cylinder passes through the top end of the support seat and extends downward; a press-fitting assembly or a disassembly assembly is arranged on the tooling base.

[0007] As a further improvement of the present invention, the press-fitting assembly comprises: a press-fitting sleeve, and the press-fitting sleeve is detachably connected to the tooling base at the bottom end.

[0008] As a further improvement of the utility model, the disassembly assembly includes: a disassembly sleeve, a disassembly buckle plate and a disassembly cover plate; the disassembly sleeve is detachably connected to the tooling base at the bottom end, the disassembly buckle plate is detachably connected to the disassembly sleeve inside the disassembly sleeve, and the disassembly cover plate is detachably connected to the disassembly sleeve.

[0009] As a further improvement of the utility model, it also includes a gasket placement rack, which is fixedly arranged on the table surface of the press-fitting table.

[0010] As a further improvement of the utility model, it also includes a tool placement tray, and the tool placement tray is fixedly arranged at the lower part of the press table.

[0011] Advantages of the utility model:

[0012] 1. The automobile reducer main gear bearing press-fitting and repairing workbench provided by the utility model solves the problem that the main gear bearing press-fitting and repairing needs to be completed at different positions and with different equipment in the past. The modified equipment integrates press-fitting and disassembly into one, reduces cost investment, and improves equipment utilization rate; solves the problem of low intact rate of main gear bearing disassembly, and the newly designed special disassembly tooling can well protect the bearing and the main gear from being damaged.

[0013] 2. The automobile reducer main gear bearing press-fitting and repairing workbench provided by the utility model solves the problem of low versatility of equipment in the process of main gear bearing press-fitting and repairing. After the transformation, the equipment only needs to replace different press-fitting tools to realize the press-fitting and disassembly operations of different main gear bearings and different needs; it solves the problem that the equipment press-fitting process is too complicated, the specifications of the gaskets are easily confused and inconvenient to take, and the production cycle is affected. According to experimental statistics: the two devices before and after the transformation simultaneously press-fit 50 main gears, and the results show that the equipment before the transformation takes 1036S, and the equipment after the transformation takes 768S, saving 268S, greatly improving the press-fitting cycle.
