DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1

[0027] Please see attached Figure 1-4 , an air-in-tube welding tool, comprising:

[0028] A placing rack 1, a positioning assembly 2 and a position verification assembly 3, wherein the placing rack 1 is U-shaped, and a plurality of supporting legs 10 are arranged on the bottom wall thereof, the positioning assembly 2 is fixedly connected to the side wall of the placing rack 1, and the position verification assembly 3 comprises a rope storage tray 30, a rope 31, a hanging ring 32 and a hanging rod 33, the rope storage tray 30 and the hanging rod 33 are respectively located at two ends of the positioning assembly 2, and the rope storage tray 30 and the hanging rod 33 are respectively fixedly connected to the side wall of the placing rack 1, one end of the rope 31 is fixedly connected to the hanging ring 32, and the other end is fixedly connected to the rope storage tray 30;

[0029] During specific use, first place the main pipe on the placement rack 1, and use the positioning component 2 to spot weld the two short pipes at both ends of the main pipe respectively. Then, pull the rope 31 out of the rope storage tray 30, pass through the upper ends of the two short pipes, and put it on the hanging rod 33 through the hanging ring 32, and then spot weld the remaining short pipes in turn. During this process, the position of the short pipe can be checked by observing whether the short pipe is released from the rope 31. If the short pipe is not released from the rope 31, it means that the vertical position of the short pipe is lower than the standard. If after the short pipe is released from the rope 31, other short tubes will be out of contact with the rope 31, which means that the vertical position of the short pipe is higher than the standard and needs to be lowered.

[0030] Specifically, the rope storage tray 30 includes a tray body 300, a rotating shaft 301 and at least one group of spiral springs 302. A rope threading hole 3001 is provided on the curved side wall of the tray body 300. Both ends of the rotating shaft 301 are respectively connected to the middle position of the plane side wall of the tray body 300 by bearings. The spiral spring 302 is located in the tray body 300, and its two ends are respectively fixedly connected to the rotating shaft 301 and the curved side wall of the tray body 300.

[0031] Specifically, one end of the rope 31 passes through the rope threading hole 3001 and is fixedly connected to the rotating shaft 301, and the rope 31 does not contact the spiral spring 302;

[0032] When the rope 31 is subjected to external force, it drives the rotating shaft 301 to rotate. During this process, it will continuously generate corresponding pulling force on the spiral spring 302. After the external force is removed, the rope 31 will be wound into the rope storage tray 30 under the reverse action force of the spiral spring 302. At the same time, in order to avoid the rope 31 and the spiral spring 302 from interfering with each other, it is necessary to ensure that the rope 31 and the spiral spring 302 do not contact each other. A partition for separating the rope 31 and the spiral spring 302 can also be provided in the rope storage tray 30.

[0033] Specifically, the positioning assembly 2 includes a positioning frame 20 and a plurality of positioning plates 21, the positioning frame 20 is fixedly connected to the side wall of the placement frame 1, and the plurality of positioning plates 21 are fixedly connected to the top wall of the positioning frame 20; the plurality of positioning plates 21 are fixedly connected to the positioning frame 20, so that when spot welding a short pipe, the spot welding of the short pipe can be directly completed by referring to the position of the positioning plate 21, thereby omitting the process of marking the long main pipe in sequence in advance.

[0034] Embodiment 2

[0035] Please see attached Figure 5-6

[0036] Specifically, the positioning assembly 2 includes a positioning frame 20, a plurality of positioning plates 21, a plurality of connecting rods 22, a plurality of force plates 23, a contact plate 24 and an adjustment assembly 25. The interior of the positioning frame 20 is hollow, and a strip hole 200 is provided on its top wall. One end of the plurality of connecting rods 22 is fixedly connected to the bottom walls of the plurality of positioning plates 21, and the other end passes through the strip hole 200 and is fixedly connected to the plurality of force plates 23 located in the positioning frame 20. The adjustment assembly 25 is movably connected to the positioning frame 20. The contact plate 24 is located between the adjustment assembly 25 and the plurality of force plates 23, and the sliding connection thereof On the inner wall of the positioning frame 20; considering the problem that the short tubes on the air bag tubes of different specifications have different spacings, and the way the positioning plate 21 is fixed on the positioning frame 20 needs to reproduce the position of the welding positioning plate 21 when spot welding different air bag tubes, therefore, by setting a strip hole 200 on the positioning frame 20, and then connecting the positioning plate located on the outside of the positioning frame 20 with the force plate 23 located on the inside of the positioning frame 20 through the connecting rod 22, the position of the positioning plate 21 can be freely moved, thereby achieving the purpose of quickly adjusting the position of the positioning plate 21, and at the same time, the position of the positioning plate 21 is limited by the contact plate 24 and the adjustment component 25.

[0037] Specifically, the adjustment assembly 25 includes an adjustment shaft 250, an adjustment handle 251, a locking pin 252 and a plurality of cams 253, one end of the adjustment shaft 250 is connected to the inner wall of the positioning frame 20 by a bearing, and the other end passes through the positioning frame 20 and is fixedly connected to the adjustment handle 251 located on the outside of the positioning frame 20, and the adjustment shaft 250 passes through a plurality of the cams 253 and is fixedly connected thereto, the cam 253 contacts the bottom wall of the contact plate 24, one end of the locking pin 252 passes through the adjustment handle 251 and contacts the positioning frame 20, and the locking pin 252 is threadedly connected to the adjustment handle 251.

[0038] Specifically, the positioning frame 20 is provided with a plurality of locking recessed holes 2520 matching the locking pin 252; the adjusting shaft 250 is driven to rotate by the adjusting handle 251, thereby driving the cam 253 to rotate, and utilizing the characteristic that the cam 253 has different diameters at different positions to change the position of the contact plate 24 in contact with it, thereby completing the locking and releasing of the position of the positioning plate 21. At the same time, in order to prevent the adjusting shaft 250 from rotating without human intervention, a locking pin 252 and a locking recessed hole 2520 matching it are provided to lock the position of the adjusting handle 251.

[0039] Embodiment 3

[0040] Specifically, at least one cylinder 11 fixedly connected to the inner bottom wall of the placement rack 1 is provided, and an arc-shaped support plate 12 fixedly connected to the inner bottom wall of the cylinder 11 is provided at one end of the piston rod of the cylinder 11 away from the cylinder 11; taking into account the possibility that the main pipeline may not match the placement rack 1, for example, when the diameter of the main pipeline is too small, the welding point will be located on the inner side of the placement rack 1 when the main pipeline is directly placed on the placement rack 1, so the cylinder 11 is arranged in the placement rack 1, and the main pipeline is supported by the arc-shaped support plate 12 on the cylinder piston rod, thereby expanding the application scope of the placement rack 1.
