Technical Field

[0001] The utility model relates to the technical field of wheel hub bearing processing, in particular to a wheel hub bearing disassembly device. Background Art

[0002] The wheel hub bearing is one of the key parts of the automobile. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub. In the third-generation wheel hub bearing shaft processing technology, there is a process that presses the inner ring onto the wheel hub bearing first, and then processes the groove as a whole, which effectively avoids the cumulative error of the groove position caused by separate processing of the two. When using this process, the inner ring must be removed from the wheel hub bearing first during installation.

[0003] At present, the disassembly device in the prior art usually includes a workbench, with two power sources arranged on the left and right sides of the workbench, a pressure block is arranged on the power source, a cylinder is arranged at the upper end of the workbench, and a push rod is fixed on the conveying end of the cylinder; its working process is: place the bearing on the workbench, start the power source, thereby pushing the pressure block against the outer wall of the inner ring, thereby clamping and fixing the inner ring, and then start the cylinder, thereby pushing the bearing downward through the push rod, thereby separating the bearing from the inner ring.

[0004] In the above solution, when the existing disassembly device clamps and fixes the inner ring, it is easy to cause damage to the outer wall of the inner ring, thereby affecting the quality of the inner ring. Utility Model Content

By providing a clamping mechanism, the inner ring of the bearing will not be damaged. The problem that the inner ring of the bearing is easily damaged when clamping and fixing the inner ring of the bearing in the prior art is solved, thereby not affecting the quality of the inner ring of the bearing.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A wheel hub bearing disassembly device comprises a frame, a workbench is arranged in the frame, a lifting assembly and a moving assembly are arranged at the lower end of the workbench, a positioning seat is fixed at the upper end of the workbench, two groups of clamping mechanisms are symmetrically arranged at the left and right ends of the frame, the clamping mechanism comprises a clamping assembly and a transmission assembly, a hydraulic cylinder is fixed at the upper end of the frame, and a push rod is fixed on the output end of the hydraulic cylinder passing through the frame.

[0008] When the inner ring of the bearing needs to be removed from the wheel hub bearing, the wheel hub bearing of the inner ring of the bearing to be removed is clamped and placed on the positioning seat to prevent the wheel hub bearing from being offset. The wheel hub bearing is driven to move to the lower end of the push rod by the moving assembly, and is coaxially arranged with the push rod, so that when the push rod moves downward, it will not abut against the upper ends of the wheel hub bearing and the inner ring of the bearing at the same time. The clamping assembly is driven by the transmission assembly to clamp and fix the inner ring of the bearing, and the hydraulic cylinder is started to push the push rod downward. The downward movement of the push rod pushes the wheel hub bearing downward. At the same time, a lifting assembly is provided so that the wheel hub bearing can move downward when subjected to an axial load, thereby separating the inner ring of the bearing from the wheel hub bearing, and the clamping assembly is driven by the transmission assembly to move outward to the desired position, so that the inner ring of the bearing is sleeved on the clamping assembly, and the push rod is controlled to return to its original position. At the same time, the wheel hub bearing is driven back to its original position by the lifting assembly, so that the inner ring of the bearing is sleeved on the wheel hub bearing, and the clamping assembly is driven by the transmission assembly to disengage from the inner ring of the bearing, so that the inner ring of the bearing can be taken out.

[0009] By providing a clamping mechanism, the inner ring of the bearing will not be damaged, thereby solving the problem that the inner ring of the bearing is easily damaged when clamping and fixing the inner ring of the bearing in the prior art, thereby not affecting the quality of the inner ring of the bearing.

When the push rod is controlled to return to its original position, multiple first compression springs rebound, thereby driving the worktable to move upward, thereby driving the wheel hub bearing back to its original position. At the same time, a guide assembly is provided to prevent the worktable from offset when moving upward or downward.

[0015] Through the above technical solution, when the inner ring of the bearing needs to be clamped and fixed, the connecting block is driven to move through the transmission component, and the movement of the connecting block drives the clamping block to press against the outer wall of the inner ring of the bearing, and at the same time, the two clamping blocks are squeezed away from each other by the inner ring of the bearing, and multiple second compression springs are compressed, so that the required clamping position can be adjusted according to the inner rings of bearings of different specifications, so that the inner ring of the bearing can be effectively clamped and fixed, and damage to the inner ring of the bearing can be prevented.

[0017] Through the above technical solution, when it is necessary to push the connecting block to move, the driving device is started to drive the rotating disk to rotate, the rotating disk rotates to drive the connecting rod to move, and the movement of the connecting rod pushes the connecting block to the desired position.

[0018] The utility model is further configured as follows: the guide assembly includes a guide rod inserted on the workbench, and the protruding end of the guide rod passes through the workbench and is fixed to the upper end of the support plate.

[0019] Through the above technical solution, when the worktable moves upward or downward, the worktable slides on the guide rod at the same time, thereby preventing the worktable from deviating when moving upward or downward.

[0020] The utility model is further configured as follows: the end of the clamping block is arc-shaped, and a rubber pad is fixed to the end of the clamping block.
