[0104] Specifically, when one of the positioning blocks 3 of the turntable 2 rotates to the bearing installation position, the bearing clamping mechanism 19 clamps the bearing 10 at the discharge end of the bearing conveying mechanism 18 to the first assembly position 7 of the positioning block 3, the bearing clamping mechanism 19 is reset, the turntable 2 rotates to the lower gear box installation position, the lower gear box clamping mechanism 22 clamps the lower gear box 11 at the discharge end of the lower gear box conveying mechanism 21 to the first assembly position 7 of the positioning block 3, so that the bearing 10 is located below the lower gear box 11, the lower gear box clamping mechanism 22 is reset, the turntable 2 rotates to the gear bearing group installation position to place the gear bearing group 12 on the lower gear box 11, the turntable 2 rotates to the pressing position, the pressing mechanism 28 and the lifting mechanism 29 are used to press the bearing 10 to the lower position of the lower gear box 11, and the lower position of the lower gear box 11 is provided with a bearing installation cavity. After the pressing station is completed, the pressing mechanism 28 and the lifting mechanism 29 are reset, the turntable 2 rotates to the screw installation station, the screw 15 moves to the second assembly station 8 of the positioning block 3 through the rotating mechanism 31, the turntable 2 rotates to the transplanting assembly station, the mobile clamping mechanism 9 is a three-axis motion platform, and a driving motor 42 and a finger cylinder are provided in the Z-axis direction of the three-axis motion platform. The driving gear of the driving motor 42 is located between the two clamping claws of the finger cylinder. When the mobile clamping mechanism 9 drives the finger cylinder and the driving motor 42 to clamp the lower gear box 11 of the first assembly station 7, the gear bearing group 1 2 is meshed with the driving gear of the driving motor 42, and then the mobile clamping mechanism 9 drives the lower gear box 11 to move to the second assembly station 8, and the driving motor 42 drives the gear bearing group 12 to rotate, and then the lifting mechanism 43 (lifting cylinder) under the screw rod 15 of the second assembly station 8 lifts the screw rod 15 and inserts it into the square hole of the gear bearing group 12. Since the square holes need to be aligned, the lifting mechanism 43 needs to drive the screw rod 15 to move upward while the gear bearing group 12 rotates. A detector is provided on the upward movement trajectory of the screw rod 15 to detect that the screw rod 15 is inserted into place.

[0105] After the screw rod 15 is assembled, the lifting mechanism 43 and the mobile clamping mechanism 9 are reset, and the turntable 2 rotates to the screw rod nut installation station. The screw rod nut installation station includes a vertical frame 57, and a horizontal beam 58 is provided on the vertical frame 57. A horizontal push cylinder 59 is provided on the horizontal beam 58. The piston rod of the horizontal push cylinder 59 is connected to the sliding plate 60. The sliding plate 60 is reciprocatingly slidably arranged on the horizontal beam 58 through the structure of the slide rail and the slider. A longitudinal beam 61 is provided on the sliding plate 60. The nut driving motor 47 is fixedly arranged on the top of the longitudinal beam 61. The motor shaft of the nut driving motor 47 passes through the horizontal fixed block at the top of the longitudinal beam 61. A longitudinal beam slide rail and a longitudinal beam slider are provided on the longitudinal beam 61. The longitudinal beam slide rail is fixed on the longitudinal beam 61.

The longitudinal beam slider is provided with a The mounting block 63 of the telescopic rod structure, the telescopic rod structure includes a fixed rod 64 that is transmission-connected to the motor shaft of the nut driving motor 47, and a movable sleeve 65 that is sleeved on the outer side of the fixed rod 64 and fixedly connected to the mounting block 63. One end of the movable sleeve 65 is connected to the clamping head 46, and the clamping head 46 is provided with a clamping groove 67 for clamping the nut 16. The cross-section of the fixed rod 64 is square, and the movable sleeve 65 is provided with a square hole for inserting the fixed rod 64. When the nut 16 is conveyed to the discharge end of the nut conveying mechanism 44, the horizontal pushing cylinder 59 drives the clamping head 46 to move to the top of the discharge end of the corresponding nut conveying mechanism 44; the vertical cylinder 62 drives the clamping head 46 to move downward to clamp the nut 16. During the downward movement of the clamping head 46, the movable sleeve 65 moves axially up and down along the outer side of the fixed rod 64. When the clamping head 46 clamps the nut 16, the vertical cylinder 62 is reset.

[0106] Before the nut 16 rotates, the anti-rotation clamping mechanism 48 first clamps the screw rod 15. The anti-rotation clamping mechanism 48 includes two anti-rotation clamping cylinders symmetrically arranged at intervals. A clamping positioning block is provided on the piston rod of each anti-rotation clamping cylinder. The clamping positioning block is provided with anti-skid patterns. This can prevent the screw rod 15 from rotating when the screw rod 15 and the nut 16 are assembled. The anti-skid patterns can also prevent damage to the outer surface of the screw rod 15. After the vertical cylinder 62 is reset, the horizontal push cylinder 59 drives the clamping head 46 to move to the position where the nut 16 and the screw rod 15 are assembled, and the vertical cylinder 62 drives again. The nut 16 moves downward toward the screw rod 15. At this time, the piston rod of the lifting and positioning mechanism 49 presses the screw rod 15 upward. The corresponding position sensor detects the upward movement of the screw rod 15. After determining that the screw rod 15 and the nut 16 have reached the corresponding assembly position, the nut drive motor 47 drives the fixed rod 64 to rotate. Due to the square hole structure, the fixed rod 64 drives the movable sleeve 65 to rotate, and the movable sleeve 65 drives the chuck 46 to rotate, and the nut 16 rotates. Since the screw rod 15 does not rotate, the nut 16 rotates and is fixed on the screw rod 15. When the nut 16 is fixed, the corresponding mechanisms are reset.

[0107] The turntable 2 then rotates to the first side gear bearing assembly installation station, the lubricating oil output station, the second side gear bearing assembly installation station, the lower gear box installation station, the screw locking station and the material feeding station in sequence.
