Description

Technical Field

[0001] The invention relates to the technical field of bearing installation, in particular to a bearing pressing device for an automobile steering gear. Background Art

[0002] The automobile steering system is a key component to ensure vehicle driving safety and handling performance. Its assembly quality directly affects the performance of the entire vehicle. Among them, the steering gear is the core component of the steering system, and the correct installation of its internal bearings is crucial.

[0003] Traditional automobile steering gear bearing pressing operations mostly rely on manual operation, that is, the operator first needs to manually place the bearing accurately on the predetermined mounting hole of the steering gear, then the operator needs to hold one end of the steering gear and place the other end of the steering gear steadily on the workbench of the pressing device to ensure that the bearing on the steering gear is vertically aligned with the pressing rod of the pressing device, and then the pressing rod of the pressing device is controlled to descend to achieve accurate pressing of the bearing. However, in this process, due to the lack of effective fixing and positioning devices, it is difficult for manual labor to always maintain the stable state of the steering gear, which easily causes the steering gear to deflect or move slightly. This deviation will make it impossible to accurately align the mounting hole on the steering gear with the pressing rod, thereby causing the bearing press-fitting problem to be skewed. Once the bearing position is found to be incorrect, the operation of the pressing device must be stopped immediately and the position of the steering gear must be readjusted, which will not only increase the uncertainty in the production process, but also reduce work efficiency. In addition, each time a steering gear bearing is installed, the above-mentioned manual operation steps need to be repeated, including placing the bearing, aligning the mounting hole and the pressing rod, and reversing the steering gear, which is troublesome to operate and has low work efficiency.

The pressure rod 202 can drive the bearing to move downward to the mounting hole 002 at the rear end of the steering gear body 001 through the swing rod 25. Then the control cabinet 101 will control the fifth electric push rod 22 to drive the connecting plate 23 to move downward and reset. The plate 23 can drive the swing rod 25 to move downward and reset. Under the action of the hinge rod 24, the swing rod 25 will rotate inward and retract to loosen the bearing, and the pressure rod 202 will continue to move downward to contact the bearing on the mounting hole 002, and press the bearing downward into the mounting hole 002 at the rear end of the steering gear body 001.

Each time the contact rod 31 contacts the valve stem 3001 of the control valve 30, it will squeeze the valve stem 3001 of the control valve 30 to rotate and open once, and the spring 32 will deform, so that the lubricating oil in the oil storage tank 27 flows into the sponge ring 29 through the connecting pipe 28, and the sponge ring 29 can absorb the lubricating oil. When the contact rod 31 is separated from the valve stem 3001 of the control valve 30, the spring 32 will return to its original state and drive the valve stem 3001 of the control valve 30 to rotate and close, thereby automatically and intermittently replenishing the lubricating oil in the sponge ring 29. When each bearing moves downward in the storage barrel 16 for loading, it will pass through the inner side of the sponge ring 29, and the sponge ring 29 can apply the lubricating oil to the outer side of the bearing to facilitate the subsequent pressing operation of the bearing.
