[0032] The tightening structure 10 connected to the base 1 includes a first active telescopic frame 11 fixedly connected to the base 1, the movable end of the first active telescopic frame 11 is fixedly connected to a branch frame 12, the branch frame 12 is fixedly connected to two sets of symmetrically arranged rotation and transverse movement mechanisms 13, the rotation and transverse movement mechanisms 13 are movably connected to a semicircular guide frame 14, the semicircular guide frame 14 is fixedly connected to an anti-skid plate 15, an arc groove 16 is provided on the semicircular guide frame 14, and multiple sets of mobile tightening components 17 are installed on the arc groove 16, the mobile tightening components 17 are in contact with the anti-skid plate 15, and the anti-skid plate 15 is used to apply friction to the mobile tightening components 17.

[0033] When in use, part of the first active telescopic rod 6 drives the rectangular support bar 7 to descend, thereby forming a depression on the surface formed by the multiple groups of rectangular support bars 7, so that part of the rectangular support bars 7 provide adaptive shape support to the gear box shell, while the depression formed in the matrix support mechanism 4 provides a accommodating space for the protruding shaft in the gear box. After the external manipulator places the gear box components on the matrix support mechanism 4, the four groups of adjustment parts 8 push a group of gear box shells to adjust the position of a group of gear box shells, and then use two groups of abutment parts 9 to abut and limit the shells after position adjustment, and then the four groups of adjustment parts 8 position the remaining shells. The bolts are then transported in an orderly manner to the movable tightening assembly 17 by an external conveying mechanism.

The driving motor 23 drives the gear 24 to rotate. The rotating gear 24 drives the two sets of racks 26 to move in opposite directions. The racks 26 drive the top frame 25 to move, so that the position of the top frame 25 is adapted to the shape of the gear box housing.

Under the guidance of the straight groove 28 and the second J-shaped groove 30, the hanging frame 36 rotates and then moves horizontally, so that the hanging frame 36 drives the semicircular guide frame 14 to move, thereby adjusting the distance between the two groups of semicircular guide frames 14.

[0036] In one case of this embodiment, the movable tightening assembly 17 includes an anti-slip block 38 that is slidably connected to the arc groove 16, the anti-slip block 38 is fixedly connected to the third motor 64, the output shaft of the third motor 64 is fixedly connected to the driving wheel 65, the driving wheel 65 abuts against the anti-slip plate 15, the anti-slip block 38 is connected to a braking portion 39 abutting against the anti-slip plate 15, the anti-slip block 38 is fixedly connected to the first sleeve 40, the first sleeve 40 is fixedly connected to the second motor 41, the output shaft of the second motor 41 is fixedly connected to the prismatic sleeve 42, the outside of the prismatic sleeve 42 is provided with a circular outer wall, the inside of the prismatic sleeve 42 is provided with a prismatic one-way groove, the prismatic sleeve 42 is rotatably installed in the first sleeve 40, and the first sleeve 40 slides A second sleeve 43 is dynamically connected, and a special-shaped column 44 slidably connected to the prismatic sleeve 42 is rotatably installed in the second sleeve 43.

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 fixedly connected to the special-shaped column 44, and the second bevel gear 48 is connected to the limited torque torsion portion 49, and the limited torque torsion portion 49 is connected to 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-slide plate 15, so that the anti-slip block 38 slides along the arc groove 16, and as the braking part 39 abuts the anti-slip plate 15 to limit the movement of the anti-slip block 38, after the torque limiting torsion part 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 torque limiting torsion part 49 to move to adjust the position of the bolt. During this period, the special-shaped column 44 and the prismatic sleeve 42 slide relative to each other. Under the drive of the second motor 41 on the prismatic sleeve 42, the prismatic sleeve 42 drives the special-shaped column 44 to rotate, and the special-shaped column 44 drives the first bevel gear 47 to rotate, and the first bevel gear 47 drives the second bevel gear 48 to rotate. The rotating second bevel gear 48 transmits driving force to the torque limiting torsion part 49, so that the torque limiting torsion part 49 twists the bolt.

[0037] In one case of this embodiment, the torque limiting torsion portion 49 includes an insulating cover 50 fixedly connected to the transmission housing 45, and a driven telescopic frame 51 is rotatably installed in the insulating cover 50. The driven telescopic frame 51 is coaxially fixedly connected to the second bevel gear 48, and a first friction plate 52 is fixedly installed on one end of the driven telescopic frame 51 away from the second bevel gear 48. The driven telescopic frame 51 consists 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 a rectangular structure, and the piston member is fixedly connected to the first friction plate 52.

By contacting the power plate 60 with the conductive ring 61, power is supplied to the electromagnet 59 in the crosshead 58, so that the electromagnet 59 magnetically attracts the bolt, so that the bolt is tightly connected to the crosshead 58. The second bevel gear 48 drives the driven telescopic frame 51 to rotate, and the driven telescopic frame 51 drives the first friction plate 52 to rotate. Since the third active telescopic rod 55 applies pressure to the pressure sensor 56, the pressure sensor 56 applies pressure to the fork frame 54, and the fork frame 54 applies pressure to the groove 53 to adjust the pressure applied by the first friction plate 52 to the second friction plate 57, thereby adjusting the maximum friction force applied by the first friction plate 52 to the second friction plate 57, and then adjusting the maximum torque applied by the first friction plate 52 to 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 is rotated into place, the first friction plate 52 and the second friction plate 57 slide relative to each other.

[0038] In one aspect of this embodiment, the braking portion 39 includes a fourth active telescopic frame 62 fixedly connected to the anti-slip block 38. A brake pad 63 is fixedly connected to the fourth active telescopic frame 62 and abuts the anti-slip plate 15. The fourth active telescopic frame 62 drives the brake pad 63 to move, causing the brake pad 63 to abut the anti-slip plate 15, thereby increasing the friction between the brake pad 63 and the anti-slip plate 15, thereby limiting the movement of the anti-slip block 38.

[0039] Example 2, based on Example 1, refer to Figure 10 and Figure 11The cross sections of the first sleeve 40 and the second sleeve 43 are both hexagonal. By setting the cross sections of the first sleeve 40 and the second sleeve 43 to be hexagonal, relative rotation between the first sleeve 40 and the second sleeve 43 is avoided.
