[0002] Bearings and retaining springs are the main mechanical transmission and fixing standard parts. They are often used to support rotating bodies to reduce their friction coefficient and ensure the transmission accuracy of their structural parts. They are also widely used in aerospace, shipbuilding and weapons manufacturing.

[0003] Currently, the assembly of bearings and retaining rings on the market still relies on manual tools or specialized, simple press-fit tools. In the aerospace industry, factors such as the high precision of assembled components, the low tolerance for errors, and the high level of skill required in the assembly process make assembly tasks more difficult and less efficient.

[0068] The present invention provides a method for assembling a bearing support and a retaining spring. This device has a simple and rational structure, making it easy to use, assemble, debug, and maintain. It simplifies the traditional manual press-fit assembly process into simple loading and unloading operations. Furthermore, it can adapt to high-precision, low-error-tolerance, and highly variable state bearing support and retaining spring assembly tasks, reducing the skill requirements for the task and replacing manual labor to complete the assembly task. This reduces human resource costs and improves the efficiency and quality of bearing support and retaining spring assembly tasks.

[0069] Example:

[0070] Step 1: Select the corresponding sizes of bearing press-fit heads 705, locating pins 703, circlip press-fit heads 504, and circlip feeding components 6 for different specifications of bearing supports 204 and circlips 604. Install the bearing press-fit head 705 on the bearing press-fit joint 303, assemble the locating pin 703 on the locating pin support 702, install the circlip press-fit head 505 on the circlip press-fit joint 404, and install the circlip feeding component 6 between the locating pins 501 of the quick-change device in the circlip feeding and positioning device 5.

[0071] Step 2: First, place the center hole of the assembly structural member bearing support 204 on the locating pin support 702 along the outer wall of the locating pin 703, and place the bearing into the assembly position of the center hole of the bearing support 204 along the conical surface of the locating pin 704. Next, place a certain number of retaining rings 604 into the retaining ring storage support 603, cover the retaining ring extrusion sleeve 605, and screw it. The retaining rings 604 are positioned by the inner wall of the retaining ring storage support 603, and the end cover 607 is fixed to the retaining ring extrusion sleeve 605. The support spring 606 squeezes the retaining ring extrusion sleeve 605 to press the retaining ring 604, ensuring that there is always a retaining ring 604 at the loading position of the retaining ring push plate 601, preventing the retaining ring 604 from getting stuck during the continuous operation of the device, meeting the fast-paced assembly requirements of the device.

[0072] Step 3: Perform secondary positioning on the bearing support 204. The right driving component 706 and the left driving component 710 of the fixture drive the right bracket 707 and the left bracket 709 of the fixture to clamp and position the bearing support 204, realizing secondary positioning to ensure the product assembly posture.

[0073] Step 4: The assembly workbench driving device 201 in the product assembly station pushing mechanism 2 is connected and fixed to the assembly positioning workbench driving bracket 712 in the product assembly positioning workbench 7, and the assembly workbench driving device 201 pushes the product assembly positioning workbench 7 to the pressing position of the bearing pressing table 3.

[0074] Step 5: The assembly workbench position recording element 207 in the product assembly station pushing mechanism 2 detects and confirms the position of the product assembly positioning workbench 7 pushed by the assembly workbench driving device 201 to determine whether the pushed position is consistent with the preset position.

[0075] Step 6. After the actual pushing position detected by the position recording element of the assembly workbench 207 is consistent with the preset press-fitting position, the bearing press-fitting table 3 pushes the bearing press-fitting head 705 to the press-fitting position to press-fit the bearing. At the same time, the pressure detection device 302 detects the press-fitting force. After determining that the press-fitting force and press-fitting position meet the assembly requirements, the bearing press-fitting is completed and the bearing press-fitting head 705 returns to a safe position.

[0076] Step 8: The assembly workbench driving device 201 in the product assembly station pushing mechanism is connected and fixed to the assembly positioning workbench driving bracket 712 in the product assembly positioning workbench 7, and the assembly workbench driving device 201 pushes the product assembly positioning workbench 7 to the press-fitting position of the retaining spring press-fitting station 4.

[0077] Step 9: Repeat step 6 to determine whether the pushed position is consistent with the preset position.

[0078] Step 9: After the positions are aligned, the lifting drive component 510 of the clamping spring loading platform drives the entire clamping spring loading platform 507 to descend, and the descending direction is maintained horizontally by the linear guide column 508 and the linear bearing 509.

[0079] Step 10: Descend to the circlip press guide sleeve 608 and complete the docking with the positioning pin 704. The contact surface is prevented from directly contacting the back surface 507 of the circlip loading table and the bearing support 204 and damaging the surface by the limit buffer bracket and the limit buffer 513.

[0080] Step 11. The 503 circlip feeding drive element pushes the 601 circlip push plate through the 505 circlip drive element connecting plate, and pushes the 604 circlip in the 603 circlip storage support to the 502 circlip press-fitting hole in the 608 circlip press-fitting guide sleeve.

[0081] Step 12: The circlip press-fitting drive cylinder 403 of the circlip press-fitting station 4 pushes the circlip press-fitting head 505 connected to the circlip press-fitting connector 404 downward, pressing the circlip 604 in the circlip press-fitting hole 502 into the assembly position. The bearing support and circlip are assembled.

[0082] Step 13. The assembly workbench driving device 201 in the product assembly station pushing mechanism 2 is connected and fixed to the assembly positioning workbench driving bracket 712 in the product assembly positioning workbench 7. The assembly workbench driving device 201 pulls the product assembly positioning workbench 7 to the initial safe position and takes out the installed bearing support 204.

[0083] Step 15: If the press-fitted bearing support 204, retaining ring 604, and bearing are to be replaced, repeat all the previous steps. If not, repeat steps 2 to 13.

[0084] The present invention has beneficial effects.
