[0038] a plurality of positioning members 500, the plurality of positioning members 500 being arranged on the mounting plate 200, and the positioning members 500 comprising mounting blocks and two positioning columns 510 capable of being slidably arranged on the mounting blocks, and the two positioning columns 510 being respectively located on opposite sides of the positioning columns 510; the positioning blocks being capable of extending into the positioning holes 111, and the two positioning columns 510 being capable of simultaneously extending out and abutting against inner walls of the positioning holes 111.

[0039] Specifically, the application is arranged with the plurality of first supports 300, the plurality of second supports 400 and the plurality of positioning members 500 on the mounting plate 200, the planetary carrier 100 is placed on the mounting plate 200, the positioning members 500 synchronously extend into the positioning holes 111 on the bottom plate 110, at this time, the plurality of first supports 300 and the plurality of second supports 400 simultaneously abut against the lower surface of the bottom plate 110 to support the planetary carrier 100; then, the rolling balls 420 on the second supports 400 rise and partially extend into the notches 412, and the planetary carrier 100 is lifted to be separated from the first supports 300; next, the two positioning columns 510 of the positioning members 500 extend outwards, the positioning columns 510 abut against the inner walls of the positioning holes 111 and drive the planetary carrier 100 to rotate, until the two positioning columns 510 simultaneously abut against the inner walls of the positioning holes 111, at this time, the planetary carrier 100 is finely adjusted to a predetermined angle; finally, the positioning members 500 are retracted, the rolling balls 420 are lowered, and the first supports 300 and the second supports 400 simultaneously support the planetary carrier 100.

[0040] Most importantly, the application can drive the rotation of the planet carrier 100 by the synchronous extension of the two positioning columns 510 to realize the angular fine adjustment of the planet carrier 100, the adjustment is more accurate, there is no situation of over-rotation and reverse rotation, and the adjustment is more rapid. In addition, since the spherical pair is formed between the ball 420 and the support column 410, the ball 420 can rotate by itself during the fine adjustment of the planet carrier 100, the friction between the ball 420 and the planet carrier 100 is rolling friction, the surface of the planet carrier 100 will not be scratched, and the rotation resistance is smaller.

[0041] Further, the upper end of the support column 410 is provided with a pressing plate 411, the pressing plate 411 has a first end face and a second end face which are opposite to each other, and the notch 412 is arranged on the pressing plate 411 and penetrates the first end face and the second end face at the same time.

[0042] The inner wall of the notch 412 is spherical, and a spherical pair is formed between the ball 420 and the inner wall of the notch 412.

[0043] Specifically, the notch 412 is arranged on the pressing plate 411, and the inner wall of the notch 412 is spherical, so that the surface of the ball 420 can be in close contact with the inner wall of the notch 412, thereby forming a spherical pair between the ball 420 and the support column 410.

[0044] Further, the first driving cylinder 430 is arranged in the support column 410 to drive the ball 420 to partially extend out of the notch 412 or retract into the support column 410.

[0045] Specifically, the ball 420 is driven to rise and fall by the extension and retraction of the first driving cylinder 430 in the support column 410.

[0046] Further, the driving block 530 is arranged in the mounting block, the driving block 530 can rise and fall in the height direction, and a sliding groove 531 is arranged on each side of the driving block 530.

[0047] One end of the positioning column 510 penetrates the mounting block and can abut or separate from the inner wall of the positioning hole 111, and the other end of the positioning column 510 is slidably arranged in the sliding groove 531.

[0048] Specifically, the two positioning columns 510 are driven to move horizontally by the upward and downward movement of the driving block 530, so that the synchronous movement of the two positioning columns 510 can be realized to accurately adjust the angle of the planet carrier 100.

[0049] Further, the two sliding grooves 531 are symmetric about the center of the driving block 530.

[0050] Specifically, since the two sliding grooves 531 are symmetric about the center of the driving block 530, that is, the inclination angles of the two sliding grooves 531 are the same, when the two driving blocks 530 slide upward or downward, the two positioning columns 510 are resisted by the sliding inner wall to extend outward by the same amount, so as to ensure that the two positioning columns 510 can be synchronously extended and retracted by the same displacement amount, and the planetary carrier 100 can be accurately adjusted to the preset angle.

[0051] Further, a second driving cylinder 540 for driving the driving block 530 to ascend and descend is arranged in the mounting block.

[0052] Specifically, the second driving cylinder 540 drives the driving block 530 to ascend and descend, and further drives the two positioning columns 510 to horizontally extend and retract.

[0053] Further, a through hole is formed on each side of the mounting block, and the positioning column 510 is slidably arranged in the through hole.

[0054] The through hole not only enables the positioning column 510 to extend outward from the mounting block, but also restricts the sliding direction of the positioning column 510, so as to ensure that the positioning column 510 moves only in the horizontal direction under the driving of the driving block 530, and further ensures the accuracy of the angle adjustment of the planetary carrier 100.

[0055] Further, a boss 511 is arranged on the peripheral wall of the positioning column 510, a spring 520 is sleeved on the positioning column 510, one end of the spring 520 can abut or separate from the boss 511, and the other end of the spring 520 can abut or separate from the inner wall of the mounting block.

[0056] Specifically, when the driving block 530 ascends, the positioning column 510 is resisted by the sliding groove 531 to extend outward, and the boss 511 abuts and gradually compresses the spring 520 in the extending process; when the driving block 530 descends, the spring 520 releases the elastic force and drives the positioning column 510 to retract, so as to reset the positioning column 510.

[0057] Further, an auxiliary supporting cylinder 320 is arranged on the supporting part, and the auxiliary supporting cylinder 320 can abut or separate from the bottom plate 110.

[0058] Further, a pressing member 310 is arranged on the first supporting member 300, the pressing member 310 is rotatably arranged to be above or beside the bottom plate 110, and the pressing member 310 is ascendably arranged to abut or separate from the bottom plate 110.
