[0026] The inner and outer bearing wheel press-fitting machine includes a press-fitting assembly 1, a load-bearing assembly 2, a wheel positioning component 3, and a bearing positioning component 4. The press-fitting assembly 1 is used to drive the load-bearing assembly 2 and to apply downward pressure. The bearing positioning component 4, the wheel positioning component 3, and the load-bearing assembly 2 are assembled sequentially from top to bottom. The wheel positioning component 3 includes a wheel positioning plate 31 and two wheel limiting rings 32. The two wheel limiting rings 32 are arranged at intervals and are arranged in an arc shape along opposite directions. A wheel limiting groove is formed between the two wheel limiting rings 32. The wheel limiting groove is used to position the driving wheel or the driven wheel. The bearing positioning component 4 has a bearing groove, which is arranged through the wheel. The bearing groove and the wheel limiting groove are arranged vertically and are connected. The bearing component 5 extends through the bearing groove and is embedded in the driving wheel or the driven wheel. The press-fitting assembly 1 is used to press the bearing component 5 and the driving wheel, or the press-fitting assembly 1 is used to press the bearing component 5 and the driven wheel.

[0027] The aforementioned inner and outer bearing wheel press-fitting machine, during the press-fitting operation, feeds the drive wheel or driven wheel and bearing component 5 respectively. Under the action of two wheel limiting rings 32, the feed drive wheel or driven wheel is positioned, and under the action of the wheel limiting groove, the feed bearing component 5 is positioned. At the same time, the bearing component 5 is aligned with the drive wheel or driven wheel. Then, the press-fitting assembly 1 transfers it to the designated position and applies downward pressure to achieve the press-fitting of the bearing component 5 with the drive wheel or driven wheel. In this way, the feeding is simple and convenient, and the automated press-fitting efficiency is high. Furthermore, the synchronous positioning of the bearing component 5 and the drive wheel or driven wheel effectively ensures the feeding accuracy of the bearing component 5 and the drive wheel or driven wheel, improves the press-fitting accuracy, and increases the qualification rate of the press-fitted products.

The bearing positioning component 4 includes a shaft positioning plate 41, which, along with the two wheel limiting rings 32, is assembled in sequence, and the upper parts of the two wheel positioning posts 33 simultaneously penetrate the shaft positioning plate 41.

[0029] Under the action of the two wheel fixing columns 33, the assembly of the shaft fixing plate 41 is reinforced and positioned, improving the assembly stability of the shaft fixing plate 41. At the same time, it realizes the direct alignment of the bearing groove and the wheel limiting groove, improving the pressing accuracy and the qualification rate of the pressed finished product.

[0030] The bearing positioning component 4 includes two plate rings 42, which are respectively installed on the shaft fixing plate 41. The two plate rings 42 are arranged with their ends spaced apart and corresponding to each other. The plate rings 42 extend in the direction away from the shaft fixing plate 41, and are used to apply external force to pick up and put down the shaft fixing plate 41.

[0036] In this way, during the press-fitting operation, the cooperation between the seat block 13 and the seat groove 43 facilitates the alignment of the press-fitting head 12 and the bearing component 5, thereby improving the press-fitting accuracy.

[0037] The pressing assembly 1 includes a transfer structure 23 and a load-bearing structure. The wheel plate 31 and the load-bearing structure are arranged in an upper and lower assembly.

[0040] The sliding component includes multiple sliding blocks, which are arranged at intervals along the length of the guide rail. Under the action of each sliding block, the movement stability of the load-bearing structure is improved.

[0041] The load-bearing structure includes an upper support plate 21, a cover frame 25, a lower support plate 26, and a bellows cover 24. The upper support plate 21, the cover frame 25, and the lower support plate 26 are assembled sequentially from top to bottom. The wheel plate 31 is stacked and assembled with the upper support plate 21. The lower support plate 26 is fixedly assembled with the sliding component. The cover frame 25 is used to install the bellows cover 24. The bellows cover 24 is unfolded or folded under driving force and is located above the screw.

[0042] The bellows cover 24 serves to shield and reduce dust, waste, and other debris from falling into the load-bearing structure, thereby extending the service life of the load-bearing structure.

[0043] The load-bearing structure includes a support column 22. The lower part of the support column 22 is fixedly arranged, and the support column 22 extends vertically upward. The support column 22 passes through the lower bearing plate 26 and is arranged correspondingly to the upper bearing plate 21. Under the action of the support column 22, it plays a supporting role and effectively bears the downward pressure, thereby improving the safety of press fitting.

[0044] The load-bearing structure includes four guide posts 27 and multiple spring members 28. The four guide posts 27 are arranged at the four corners along the support post 22. The upper part of the guide post 27 is connected to the upper support plate 21, and the lower part of the guide post 27 is movably embedded in the lower support plate 26. The two ends of the spring member 28 are connected to the upper support plate 21 and the lower support plate 26 respectively. The spring member 28 is used to reset the upper support plate 21 and is located between two guide posts 27.

[0045] The four guide posts 27 improve the stability of the upper bearing plate 21 and prevent the upper bearing plate 21 from shifting. The spring 28 facilitates the reset of the upper bearing plate 21 when the downward pressure is removed.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
