[0025] The opposite side of the side seat 8 is provided with straight rod 7, the surface of straight rod 7 is slidably matched with side ring 6, the top of side ring 6 is adaptively installed with sleeve 4.

[0026] One side of screw rod 33 extends into the adaptive slot where side seat 8 starts, and the length of screw rod 33 is less than the length of straight rod 7.

[0027] Specifically, through the cooperation of the sleeve 4 and the positioning member 3, the displacement of the welding station 5 is more stable, the guide rail displacement is optimized, the displacement jitter problem at the corner of the guide rail is improved, the welding station 5 can also be accurately welded, the transmission cooperation of the screw rod 33, the driven tooth 32 and the driving tooth 31 converts the meshing transmission between the gears into linear displacement, the welding station 5 can not only adjust the spacing but also expand the range, and the operator can complete the welding without large amplitude movement, which is very portable and easy to use; the penetration cooperation of the straight shaft 2 and the chassis base 12 supports the rotation of the straight shaft 2, and the rotation of the straight shaft 2 is more stable.

[0028] Through the arrangement of the side seat 8 and the straight rod 7, the side ring 6 can displace linearly, and the sleeve 4 can be supported, so that the sleeve 4 is always in thread cooperation with the surface of the screw rod 33, and the length of the screw rod 33 is less than the length of the straight rod 7, so that the thread displacement is continuous and durable, the extension range of the welding station 5 is larger, and the welding is more timely.

[0029] The side of the sleeve 4 is provided with a lead spring 10; for example, as shown in Figures 2-4 .

[0030] The end face of the lead spring 10 away from the sleeve 4 is adaptively provided with a placement ring 9, and the placement ring 9 is a detachable structure.

[0031] One side of the placement ring 9 is provided with a contraction pair of rods 11, and the upper surface of the placement ring 9 is provided with an anti-skid pattern.

[0032] The number of the driven teeth 32 is several, the arrangement mode of the several driven teeth 32 is annular array, and the gear radii of the driven teeth 32 and the driving teeth 31 are different.

[0033] Specifically, through the cooperation of the lead spring 10 and the placement ring 9, the parts can be placed on the surface of the placement ring 9 before welding, the contraction pair of rods 11 is arranged to enable the placement ring 9 to be flexibly spliced or detached, the number of parts placed can be adjusted in time according to the specific requirements of welding, the anti-skid pattern is further arranged to enable the placement ring 9 to be placed in one position for a long time without falling off, and the necessary time for welding is shortened, and the annular array of the several driven teeth 32 enables the welding station 5 to be welded at the same time, and the welding efficiency is improved.

[0034] The inner side of the welding station 5 is provided with a fine sand layer; for example, as shown in Figures 3-5 .

[0035] The layer paving mode of the fine sand layer is uniform paving.

[0036] The bottom of the straight shaft 2 is adaptively provided with a driving motor 1, and the surface of the driving motor 1 is arranged and provided through a straight column and the chassis base 12.

[0037] Specifically, the fine sand layer arranged inside the welding station 5 can support the part with friction force on the side during welding, which is conducive to improving the problem of part displacement during welding. Meanwhile, the adaptive installation of the driving motor 1 and the straight shaft 2 provides a power source for the straight shaft 2, helping the welding station 5 to stretch in a ring shape.

[0038] Working principle: first, place the parts on the surface of the plurality of placement rings 9, then start the driving motor 1 to rotate the straight shaft 2, which drives the driving gear 31 to rotate synchronously, and then through the meshing between the teeth, the driven gear 32 rotates vertically. This rotation mode will make the sleeve 4 displace along the surface of the screw rod 44. Then install the side ring 6 on the side of the sleeve 4, and the side ring 6 is in sliding fit with the straight rod 7. In the process of continuous displacement of the sleeve 4, the extension of the connecting spring 10 will make the placement ring 9 move along the surface of the annular track, thereby shortening the distance between the part and the welding station 5. Finally, polish and lay a fine sand layer inside the welding station 5 to help the part keep the relative position unchanged.
