[0041] like Figure 5 As shown, the positioning assembly 41 includes a positioning platform 411, a second positioning seat 412, a positioning cylinder 413, a positioning sleeve 414, and a second rotary pressing cylinder 415. The positioning platform 411 is fixed above the pressing base plate 421 by a support cover 417, which also has a transparent observation window. The second positioning seat 412 is located on the top of the positioning platform 411, and the top of the second positioning seat 412 has a groove for placing the semi-finished drive shaft assembly. The positioning cylinder 413 is fixed above the positioning platform 411.

[0042] During end cap pressing, the support positioning block 425 is in its initial position. The end cap is picked up by the material handling mechanism 5 and placed into the groove of the support positioning block 425. Then, the rotary cylinder 424 rotates 90° and the lifting cylinder 423 rises, aligning the end cap on the support positioning block 425 with the drive shaft on the positioning assembly 41. Then, the end cap pressing cylinder 422 is activated, pushing the support positioning block 425 toward the drive shaft to press the end cap onto the drive shaft, completing the assembly of the drive shaft assembly. The rotary cylinder 424 and the lifting cylinder 423 are used to facilitate the loading of the end cap and drive shaft assembly semi-finished product.

[0043] Example 2

[0044] Based on the structure of Example 1, such as Figure 6 , 7 As shown, there are two bearing pressing mechanisms 3, which are arranged opposite to each other on both sides of the positioning mechanism 2, and can press the bearings at both ends of the transmission shaft at the same time.

[0045] When assembling the bearing, the material handling mechanism 5 clamps the drive shaft and places it into the groove of the positioning seat 21. Then, the support pushing cylinder 24 and the lifting cylinder 25 are activated to align the support block 26 with the positioning seat 21 and support the suspended end of the drive shaft. Then, the rotary pressing cylinder 22 is activated to drive the pressing plate 23 to press the drive shaft, and the drive shaft is fully positioned. Simultaneously, the bearing feeding assemblies 32 on both sides of the positioning mechanism 2 feed the bearings. The bearings slide into the arc-shaped opening slots 3131 of the corresponding pressing assembly 31 through the guide grooves 3251 on the guide seat 325. The pressing assemblies 31 on both sides can be started at the same time and move towards the positioning mechanism 2 in the middle to press the bearings on the pressing block 313 onto both ends of the transmission shaft. After pressing into place, the bearing pressing cylinder 311 retracts. At the same time as the bearing pressing cylinder 311 retracts, the check cylinder 315 extends to abut against the bearing to prevent the retraction from causing the bearing to retract. At the same time, the pressing of the bearings at both ends of the transmission shaft is completed. Then, the material taking mechanism 5 takes out the transmission shaft with the bearings pressed and unloads it to the end cover pressing mechanism 4.

[0046] In summary, this utility model integrates bearing press-fitting and end cap press-fitting into one unit, which can automatically complete the assembly of the drive shaft assembly. In addition, when press-fitting bearings, it can press-fit the bearings at both ends of the drive shaft simultaneously, eliminating the need for multiple positioning, making the operation more convenient and faster, and greatly improving the quality and efficiency of bearing press-fitting. Furthermore, the bearings can automatically slide into the press-fitting block by pushing the material, eliminating the need for transfer by the material handling mechanism, simplifying the equipment, and further improving the assembly efficiency.
