[0017] During use, a part of the first active telescopic rod 6 drives the rectangular support bar 7 to descend, so that a depression is formed on the surface composed of multiple groups of rectangular support bars 7. While some of the rectangular support bars 7 provide a shape support adapted to the outer shell of the gearbox, the depression formed in the matrix support mechanism 4 provides a receiving space for the protruding shaft in the gearbox. After the external manipulator places the components of the gearbox on the matrix support mechanism 4, the four adjustment parts 8 push a group of outer shells of the gearbox to adjust the position of a group of outer shells of the gearbox. Then, the two abutting parts 9 are used to abut and limit the position-adjusted outer shell. Then, the four adjustment parts 8 adjust the positions of the remaining outer shells. Then, as the external conveying mechanism orderly conveys bolts to the mobile tightening assembly 17, the mobile tightening assembly 17 magnetically attracts the bolts, and the mobile tightening assembly 17 moves along the arc-shaped groove 16. Then, the rotating and transverse movement mechanism 13 drives the semi-circular guide frame 14 to move, and the splitting head frame 12 drives the splitting head frame 12 to move to adjust the height of the two rotating and transverse movement mechanisms 13, thereby further adjusting the position of the bolts, so that the distribution positions of the bolts correspond one by one to the positions of the screw holes on the housing of the gearbox.

The driving motor 23 drives the gear 24 to rotate. The rotating gear 24 drives the two racks 26 to move in opposite directions. The rack 26 drives the top frame 25 to move, so that the position of the top frame 25 is adapted to the shape of the outer shell of the gearbox. The second active telescopic frame 18 drives the position of the third active telescopic frame 20 by driving the limit sleeve 19 to move, so that the top frame 25 abuts against the outer shell of the gearbox.

A straight groove 28 is formed in the suspension 27. A first J-shaped groove 29 is formed in the suspension 27. A second J-shaped groove 30 is formed in the suspension 27.

A protruding shaft 35 is slidably connected to the driving groove 34. The protruding shaft 35 is slidably connected with the first J-shaped groove 29. The protruding shaft 35 is fixedly connected with a hanging frame 36. The hanging frame 36 is movably connected with the semi-circular guiding frame 14. The movable connection mode between the hanging frame 36 and the semi-circular guiding frame 14 can be selected as using a pin connection or using a connection mode of a screw and a nut. The hanging frame 36 is fixedly connected with two sets of stepped shafts 37. The two sets of stepped shafts 37 are slidably connected with the suspension 27. One set of stepped shafts 37 is slidably connected with one straight groove 28, and the other set of stepped shafts 37 is slidably connected with the second J-shaped groove 30. The first motor 31 drives the lead screw 32 to rotate. The rotating lead screw 32 drives the driving frame 33 to move. The driving groove 34 squeezes the protruding shaft 35 to move. The protruding shaft 35 drives the hanging frame 36 to move. The hanging frame 36 drives the two sets of stepped shafts 37 to move, so that the two sets of stepped shafts 37 respectively move along the straight groove 28 and the second J-shaped groove 30.

[0020] In a case of this embodiment, the moving and tightening assembly 17 includes an anti - detachment block 38 slidably connected to the arc - shaped groove 16. The anti - detachment block 38 is fixedly connected with a third motor 64. The output shaft of the third motor 64 is fixedly connected with a driving wheel 65. The driving wheel 65 abuts against the anti - slip plate 15. The anti - detachment block 38 is connected with a braking portion 39 that abuts against the anti - slip plate 15. The anti - detachment block 38 is fixedly connected with a first sleeve body 40. The first sleeve body 40 is fixedly connected with a second motor 41. The output shaft of the second motor 41 is fixedly connected with a rhombic sleeve 42. The rhombic sleeve 42 is provided with a circular outer wall on the outside and a rhombic one - way groove on the inside. The rhombic sleeve 42 is rotatably installed in the first sleeve body 40. The first sleeve body 40 is slidably connected with a second sleeve body 43. An abnormal - shaped column 44 that is rotatably installed in the second sleeve body 43 and slidably connected with the rhombic sleeve 42 is arranged in the second sleeve body 43. The abnormal - shaped column 44 is composed of a cylinder rotatably connected to the second sleeve body 43 and a prism slidably connected with the rhombic sleeve 42 that are fixedly connected to each other. The second sleeve body 43 is fixedly connected with a transmission housing 45. A second active telescopic rod 46 is installed between the transmission housing 45 and the anti - detachment block 38. A first bevel gear 47 is rotatably installed in the transmission housing 45, and a second bevel gear 48 is rotatably installed in the transmission housing 45. The first bevel gear 47 and the second bevel gear 48 are meshed with each other. The first bevel gear 47 is coaxially and fixedly connected with the abnormal - shaped column 44. The second bevel gear 48 is connected with a limited - torque torsion portion 49. The limited - torque torsion portion 49 is connected with the transmission housing 45. As the third motor 64 applies torque to the driving wheel 65, the driving wheel 65 rolls on the surface of the anti - slip plate 15, so that the anti - detachment block 38 slides along the arc - shaped groove 16. And as the braking portion 39 abuts against the anti - slip plate 15, the movement of the anti - detachment block 38 is restricted. After the limited - torque torsion portion 49 magnetically attracts the bolt, the second active telescopic rod 46 drives the transmission housing 45 to move, and the transmission housing 45 drives the limited - torque torsion portion 49 to move to adjust the position of the bolt. During this period, the abnormal - shaped column 44 and the rhombic sleeve 42 slide relative to each other. Driven by the second motor 41 for the rhombic sleeve 42, the rhombic sleeve 42 drives the abnormal - shaped column 44 to rotate. The abnormal - shaped column 44 drives the first bevel gear 47 to rotate. The first bevel gear 47 drives the second bevel gear 48 to rotate. The rotating second bevel gear 48 delivers driving force to the limited - torque torsion portion 49, so that the limited - torque torsion portion 49 twists the bolt.

[0021] In a case of this embodiment, the torque-limiting torsion part 49 includes an insulating cover 50 fixedly connected to the transmission housing 45. A driven telescopic frame 51 is rotatably installed in the insulating cover 50. The driven telescopic frame 51 is coaxially and fixedly connected to the second bevel gear 48. One end of the driven telescopic frame 51 away from the second bevel gear 48 is fixedly installed with a first friction plate 52. The driven telescopic frame 51 is composed of a rotating sleeve fixedly connected to the second bevel gear 48 and a piston member slidably connected to the rotating sleeve. The inner cavity of the rotating sleeve is of a rectangular structure. The piston member is fixedly connected to the first friction plate 52. Grooves 53 are formed on the circumferential surface of the first friction plate 52. A fork 54 is rotatably connected to the grooves 53. A third active telescopic rod 55 is fixedly installed in the insulating cover 50. The moving end of the third active telescopic rod 55 is fixedly connected to a pressure sensor 56. The pressure sensor 56 is fixedly connected to the fork 54. The first friction plate 52 abuts against a second friction plate 57. The second friction plate 57 is fixedly connected to a crosshead 58. An electromagnet 59 is fixedly installed in the crosshead 58. The electromagnet 59 is electrically connected to two sets of electrical connection plates 60 fixedly connected to the crosshead 58. The electrical connection plates 60 are slidably connected to a conductive ring 61 fixedly installed in the insulating cover 50. The conductive ring 61 is externally connected to an external power supply. By means of the contact between the electrical connection plates 60 and the conductive ring 61, the electromagnet 59 in the crosshead 58 is powered, so that the electromagnet 59 magnetically attracts the bolt, making the bolt tightly connected to the crosshead 58. The second bevel gear 48 drives the driven telescopic frame 51 to rotate. The driven telescopic frame 51 drives the first friction plate 52 to rotate. And because the third active telescopic rod 55 presses on the pressure sensor 56, the pressure sensor 56 presses on the fork 54, and the fork 54 presses on the grooves 53 to adjust the pressure exerted by the first friction plate 52 on the second friction plate 57, so as to adjust the maximum friction force exerted by the first friction plate 52 on the second friction plate 57, and further adjust the maximum torque exerted by the first friction plate 52 on the second friction plate 57. As the first friction plate 52 drives the second friction plate 57 to rotate, the second friction plate 57 drives the crosshead 58 to rotate, so that the bolt rotates. After the bolt rotates in place, the first friction plate 52 and the second friction plate 57 slide relative to each other.

[0022] In a case of this embodiment, the braking part 39 includes a fourth active telescopic frame 62 fixedly connected to the anti-disengagement block 38. The fourth active telescopic frame 62 is fixedly connected to a brake pad 63 that abuts against the anti-slip plate 15. The fourth active telescopic frame 62 drives the brake pad 63 to move, so that the brake pad 63 abuts against the anti-slip plate 15, thereby increasing the friction force between the brake pad 63 and the anti-slip plate 15 to limit the movement of the anti-disengagement block 38.

[0023] Embodiment 2, on the basis of Embodiment 1, refer to Figure 10 and Figure 11, the cross-sections of the first set of bodies 40 and the second set of bodies 43 are both hexagonal. By setting the cross-sections of the first set of bodies 40 and the second set of bodies 43 to be hexagonal, relative rotation between the first set of bodies 40 and the second set of bodies 43 is avoided.

[0024] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
