[0045] The mounting frame 38 is fixedly installed on the top of the second lifting seat 9, and the welding head 37 is movably installed on the outer side of the clamping inner support assembly 4 and the positioning assembly 2 through the connecting block 34. When welding the metal hose, the worker needs to weld the metal hose and the connector. The worker adjusts the position of the positioning assembly 2 and the sliding seat 5 in the guide rail 6 according to the position of the welding assembly 3, and clamps and fixes the metal hose and the connector through the positioning assembly 2 and the clamping inner support assembly 4, respectively. The clamping inner support assembly 4 clamps the connector while supporting inside the metal hose to stably support the welding position of the metal hose, preventing the hose in the connector from deforming and failing to fit the inner wall of the connector when the connector is sleeved outside the metal hose and welded by the welding assembly 3, resulting in deviation of the welding point.

[0046] The second embodiment is based on the first embodiment. Please refer to Figures 8 to 10 The clamping piece 46 includes a connecting plate 461, a fixed plate 462 is fixedly installed on the outer surface of the connecting plate 461, a support block 464 is fixedly installed inside the fixed plate 462, three support blocks 464 are provided, a bending frame 463 is fixedly installed on the bottom of the three support blocks 464, and clamping pieces 465 are fixedly installed on both sides of the outer surface of the bending frame 463. After the worker sleeves the connector outside the extension rod 44, the connector is moved downwardly to the bending frame 463. At this time, the connector extrudes the clamping pieces 465, so that the clamping pieces 465 and the extrusion pads 466 are deformed and clamped on the outer side of the connector under stress, so as to flexibly clamp the connector from multiple angles, avoiding that the clamping force is too large to cause deformation of the connector and the metal hose.

[0047] The connecting plate 461 is fixedly installed on one side of the outer surface of the side connecting block 43, the clamping pieces 465 are made of flexible material, the surface of the clamping pieces 465 is provided with extrusion pads 466, and the extrusion pads 466 are clamped on the outer surface of the connector.

[0048] The third embodiment is based on the first and second embodiments. Please refer to Figures 11 to 12As shown, the support piece 45 comprises an extension pipe 451, the inside of the extension pipe 451 is fixedly installed with a middle block 453, the outer surface of the middle block 453 is fixedly installed with four through plates 452, the four through plates 452 are symmetrically arranged with the extension pipe 451 as the center, the through plates 452 extend to the outside of the extension pipe 451, the middle of the outer surface of the through plate 452 is fixedly installed with a round rod 454, the inside of the round rod 454 is fixedly installed with a mounting block 458, the outer surface of the mounting block 458 is rotatably installed with a rotating rod 455 on both sides, the outer surface of the rotating rod 455 is fixedly installed with a connecting rod 456, and the outer surface of the connecting rod 456 is fixedly installed with an inner-attached arc pad 457. When the staff sets the metal hose on the surface of the inner-attached arc pad 457, the inner-attached arc pad 457 adjusts the position of the rotating rod 455 according to the inner diameter of the metal hose, so that the rotating rod 455 drives the connecting rod 456 to rotate on both sides of the mounting block 458. Since the connecting rod 456 is installed at both ends of the inner-attached arc pad 457, the two connecting rods 456 stretch the inner-attached arc pad 457 when rotating, so as to support the metal hose according to the inner diameter of the metal hose. The plurality of inner-attached arc pads 457 support the metal hose to support and shape the metal hose, so as to avoid deformation of the thin-walled metal hose during welding and affect the welding effect.

[0049] The extension pipe 451 is fixedly installed on the outer surface of the extension rod 44, the inner-attached arc pad 457 is made of flexible material, and the inner-attached arc pad 457 is attached to the inner wall of the metal hose.

[0050] In use, when the staff welds the metal hose, the staff needs to weld the metal hose and the connector, adjusts the position of the positioning assembly 2 and the sliding seat 5 in the guide rail 6 according to the position of the welding assembly 3, and fixes the metal hose and the connector by the positioning assembly 2 and the clamping inner support assembly 4 respectively. The clamping inner support assembly 4 supports the inside of the connector while clamping the connector, so as to stably support the welding position of the metal hose, prevent the hose in the connector from deforming when the connector is sleeved outside the metal hose and welded by the welding assembly 3, and prevent the hose from being unable to be attached to the inner wall of the connector, resulting in deviation of the welding point.

[0051] When the metal hose and the connector are welded, the staff sets the connector on the outside of the support piece 45 and moves the connector towards the clamping piece 46, so that the clamping piece 46 clamps the connector. After the connector is clamped and fixed, the staff adjusts the position of the sliding seat 5, so that the sliding seat 5 drives the clamping inner support assembly 4 to move towards the position of the positioning assembly 2. At this time, the support piece 45 is located outside the positioning assembly 2. Then the staff sets the metal hose through the positioning assembly 2 and on the surface of the support piece 45. The support piece 45 supports the inside of the metal hose while the metal hose is connected with the connector, so as to facilitate subsequent welding work.

[0052] When the worker sets the metal hose on the surface of the inner arc pad 457, the inner arc pad 457 adjusts the position of the rotating rod 455 according to the inner diameter of the metal hose, so that the rotating rod 455 drives the connecting rod 456 to rotate on both sides of the mounting block 458. Since the connecting rod 456 is installed at both ends of the inner arc pad 457, the two connecting rods 456 stretch the inner arc pad 457 when they rotate, so that multiple groups of inner arc pads 457 support the metal hose according to the inner diameter of the metal hose, so as to support and shape the metal hose, and avoid deformation of the thin-walled metal hose during welding, which affects the welding effect.

[0053] After the worker sets the joint on the outside of the extension rod 44, he moves the joint downward of the bending frame 463, at which time the joint extrudes the clamping piece 465, so that the clamping piece 465 and the extrusion pad 466 are deformed and clamped on the outside of the joint to flexibly clamp the joint from multiple angles, avoiding excessive clamping force that causes the joint to deform with the metal hose.

[0054] When clamping and fixing the metal hose, the worker moves the clamping inner support assembly 4 to the outside of the clamping block 23, the worker places the metal hose on the top of the bottom support frame 27 and passes through the rotating plate 24, so that the metal hose is set on the surface of the supporting piece 45, so that the metal hose is supported and shaped by the supporting piece 45. Then the worker adjusts the position of the guide sliding block 25 according to the shape of the metal hose, so that the guide sliding block 25 drives the inner clamping plate 22 and the clamping block 23 to slide on the surface of the guide rod 26, and clamps the metal hose through the clamping block 23. When the welding head 37 welds the metal hose and the joint, the worker starts the rotating plate 24, which drives the metal hose clamped in the clamping block 23 to rotate. Since the metal hose is in contact with the supporting piece 45 inside, the supporting piece 45 and the extension rod 44 rotate when the metal hose rotates, so as to drive the joint clamped by the clamping piece 46 on the outside of the extension rod 44 to rotate, so as to facilitate the welding head 37 to weld the metal hose and the joint connection.

[0055] After the metal hose and the joint are connected and fixed, the worker starts the driving member 31, which drives the connecting block 34 to rotate to drive the limiting frame 35 to rotate, so as to adjust the inclination angle of the welding head 37, so that the welding head 37 welds the metal hose and the joint connection.
