After the mechanical clamping jaw 440 grabs the main body to the main body positioning member 310, the third cylinder 320 operates to drive the pressing block 330 to rotate towards the main body positioning member 310 to press the main body 10 on the main body positioning member 310, and after the pressing block 330 is pressed on the main body 10, the main body 10 can be prevented from rotating when the nut 11 is assembled, after the nut 11 is assembled, the third cylinder 320 drives the pressing block 330 to rotate towards the direction away from the main body positioning member 310, so that the pressing block 330 releases the pressing on the main body 10, and the mechanical clamping jaw 440 takes out the assembled pipe joint from the main body positioning member 310.

As shown in fig. 10 and 11, the tightening mechanism 500 includes: a second fixing seat 510 disposed on the machine 100, wherein a fourth cylinder 520 is disposed on the second fixing seat 510; a second movable base 530 disposed on the second fixed base 510 and connected to an output end of the fourth cylinder 520, wherein the second movable base 530 is provided with a rotatable connection block 540, and the second movable base 530 is provided with a fifth cylinder 550 for driving the connection block 540 to rotate; the middle position of the rotating motor 560 is connected to the connecting block 540, the output end of the rotating motor 560 is provided with a positioning member 570, and the positioning member 570 is used for receiving the nut 11 and the inner ring 12 grabbed by the feeding mechanism 600.

The positioning element 570 is arranged in a vertical direction in an initial state, after the clamping jaw assembly 230 captures the nut 11 and the inner ring 12 on the positioning seat 120 onto the positioning element 570, the fifth cylinder 550 acts to drive the connecting block 540 to rotate 90 °, the connecting block 540 can drive the rotating motor 560 and the positioning element 570 arranged at the output end of the rotating motor 560 to rotate, after the positioning element 570 rotates 90 °, the fourth cylinder 520 drives the second moving seat 530 to move towards the main body positioning element 310, the second moving seat 530 can drive the rotating motor 560 and the positioning element 570 to move towards the main body when moving, when the positioning element 570 moves to a preset position, the rotating motor 560 drives the positioning element 570 to rotate, and when the positioning element 570 rotates, the nut 11 placed on the positioning element 570 is driven to be screwed with the main body 10 on the main body positioning element 310.

As shown in fig. 12 and 13, the positioning member 570 includes: at least three main body blocks 571 arranged in a stacked manner, and every two adjacent main body blocks 571 are flexibly connected; a nut positioning block 572 which is detachably provided on the uppermost layer of the positioning member 570, the nut positioning block 572 being provided with a hexagonal positioning hole for positioning the nut 11; and two semicircular inner ring positioning blocks 573 detachably arranged at the middle position of the nut positioning block 572, wherein a spring is arranged between the two inner ring positioning blocks 573, when the feeding mechanism 600 grabs the inner ring 12 onto the positioning block 570, the inner ring 12 can be clamped on the outer side wall of the inner ring positioning block 573, and the spring arranged between the inner ring positioning blocks 573 can apply pushing force to the two inner ring positioning blocks 573, so that the two inner ring positioning blocks 573 are kept in a spread state all the time, and the inner ring is clamped on the outer side wall of the inner ring positioning block.

When the positioning member 570 drives the nut 11 and the main body 10 to be screwed together, the axial direction of the positioning member 570 needs to be collinear with the axial direction of the main body 10 to ensure that the nut 11 can be perfectly installed on the main body 10, but this is difficult to achieve in practical operation because machining of the nut 11 and the main body 10 and machining and installation of the main body positioning member 310 and the positioning member 570 certainly have errors, and the flexibly connected main body block 571 can well solve the above problems, and when the nut 11 is installed, even if the axial direction of the nut 11 is not collinear with the axial direction of the main body 10, the flexibly connected main body block 571 can slightly swing during screwing of the nut 11, so that the axial direction of the nut 11 is always collinear with the axial direction of the main body 10 during assembly, and the detachable nut positioning block 572 and positioning block 573 can facilitate installation requirements of nuts 11 and inner rings 12 of different sizes.

As shown in fig. 3 and 9, the feeding mechanism 600 includes: a third fixing frame 610; the third removes frame 620, its mobilizable setting is on third mount 610, is equipped with sixth cylinder 630 along vertical direction on the third removes frame 620, and the output of sixth cylinder 630 is equipped with nut clamping jaw cylinder 640.

When the rotating disc 110 drives the positioning seat 120 to rotate to a position right below the feeding mechanism 600, the third moving frame 620 moves towards the positioning seat 120 to move the nut clamping jaw cylinder 640 to a position right above the positioning seat 120, then the sixth cylinder 630 acts to drive the nut clamping jaw cylinder 640 to move downwards, when the nut clamping jaw cylinder 640 moves to a preset position, the nut 11 and the inner ring 12 placed on the positioning seat 120 are grabbed, then the sixth cylinder 630 drives the nut clamping jaw cylinder 640 to move upwards, after the clamping jaw of the nut 11 moves to an initial position, the third moving frame 620 moves on the third fixing frame 610 until the nut clamping jaw cylinder 640 moves to a position right above the positioning part 570, and then the nut clamping jaw cylinder 640 places the nut 11 and the inner ring 12 grabbed thereon on the positioning part 570.

In this embodiment, three feeding mechanisms 600 are required to be disposed to meet the feeding requirement of the nuts 11 because three nuts 11 need to be assembled on one main body, and the mounting positions of the nuts 11 in different directions on the main body are different in distance from the rotating disc 110, so the sizes and structures of the three feeding mechanisms 600 are not the same, and the difference is mainly reflected in the size of the third fixing frame 610 and whether the movable manner of the third movable frame 620 on the third fixing frame 610 is motor-driven or cylinder-driven.
