[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the welding equipment inserts the first extension pipe between the two first clamping blocks, and then starts the electric telescopic rod. The electric telescopic rod carries the first slider at the output end to slide along the first slide groove, and moves synchronously with the movement of the first slider. When the first clamping block moves, it moves with the second horizontal axis of its outer wall and finally contacts the outer wall of the third rotating ring. As the resistance force increases, since the first inclined groove is set as an inclined groove, the first guide rod of its inner wall is also inclined. At this time, the first clamping block begins to slide along the first guide rod with the second slider after being subjected to the resistance force, and the first return spring is compressed during sliding to facilitate subsequent return. As the second slider slides, the first clamping blocks on both sides approach each other to clamp the first extension pipe between the two first clamping blocks, and at this time, the ends of the first extension pipe and the second extension pipe are also aligned with each other at the joint.

[0015] In the present invention, for a welding device, the sliding frame reciprocates left and right. The left - and - right reciprocating movement of the sliding frame drives the second fixing frame and the third fixing frame to reciprocate slightly left and right together. The slight left - and - right movement of the second fixing frame and the third fixing frame causes the flux to drop in a curved path, and promotes the welding of the electric welding gun at the joint to be in a wavy curved path, making the welding more uniform.

[0037] In this embodiment: During the production of products such as clothes, sewing work is usually required. During the sewing process, in order to prevent the displacement of the fabric, the fabric is usually clamped and limited by using a fixture. During the production of the sewing fixture, according to different usage scenarios, extension pipes of different lengths can be welded to extend the length of the fixture and increase the usage range of the fixture; At present, when the welding device of the sewing clamp extension tube currently available on the market is used for butt extension welding of some pipe fittings with thicker pipe walls, if the circumferential seam welding is performed at the joint of the two pipe fittings according to the traditional welding method, the inner wall part may not be welded and fused due to the thick pipe wall, resulting in a low stress limit at the joint after the pipeline processing is completed; In order to avoid the above situation, during use, the second extension pipe 43 is inserted into the middle of the two second clamping blocks 42, and then the two cylinders 41 are started, and the output ends of the two cylinders 41 bring the second clamping blocks 42 closer to each other to clamp the second extension pipe 43 between the two second clamping blocks 42; The first extension pipe 30 is inserted between the two first clamping blocks 12, and then the electric telescopic rod 2 is started. The electric telescopic rod 2 slides along the first slide groove 3 with the first slider 4 at the output end, and moves synchronously with the first clamping block 12 as the first slider 4 moves. When the first clamping block 12 moves, it moves with the second transverse axis 44 of its outer wall and finally contacts the outer wall of the third rotating ring 40. As the contact force increases, since the first inclined groove 8 is set as an inclined groove, the first guide rod 9 of its inner wall is also inclined. At this time, the first clamping block 12 begins to slide along the first guide rod 9 with the second slider 10 after being subjected to the contact force, and the first return spring 11 is compressed during sliding to facilitate subsequent reset. As the second slider 10 slides, the first clamping blocks 12 on both sides approach each other to clamp the first extension pipe 30 between the two first clamping blocks 12, and at this time, the ends of the first extension pipe 30 and the second extension pipe 43 are also aligned with each other at the joint. As the transmission gear ring 6 rotates, the second rotating ring 13 rotates synchronously. The guide groove 14 on the second rotating ring 13 must ensure that the first transverse axis 26 is at the highest point of the outermost side of the guide groove 14 in the initial state. As the second rotating ring 13 rotates, the first transverse axis 26 will slide along the highest point of the guide groove 14 due to the rotation of the second rotating ring 13. The sliding causes the first transverse axis 26 to bear downward force with the first fixing frame 25, causing the first fixing frame 25 to slide downward along the second guide rod 20 with the third slider 21, causing the second fixing frame 28 and the third fixing frame 29 to move downward with the third slider 21, causing the second fixing frame 2 The welding gun 32 and the second ball 37 corresponding to the third fixing frame 29 are both moved downward to contact the joint of the two pipes, wherein the storage frame 33 is located at the lowest point of the joint of the first extension pipe 30 and the second extension pipe 43. After the second ball 37 is contacted, it presses the moving ring 36 upward, causing the moving ring 36 to stretch the fourth reset spring 35 to move upward, and the position of the moving ring 36 will press the rotating plate 34 upward, causing the two rotating plates 34 to rotate along the hinge, causing the two rotating plates 34 to release the blockage of the inner wall of the storage frame 33, and at this time, the flux powder in the storage frame 33 will fall to the inner wall of the moving ring 36; Since the third fixing bracket 29 is located between the two first clamping blocks 12, when the first extension pipe fitting 30 is inserted between the two first clamping blocks 12, the third fixing bracket 29 is then inside the inner wall of the first extension pipe fitting 30. At this time, the fixing frame 31 corresponding to the second fixing bracket 28 is facing the joint of the outer walls of the two pipe fittings, and the fixing frame 31 corresponding to the third fixing bracket 29 is facing the joint of the inner walls of the two pipe fittings; And as the second horizontal shaft 44 abuts against the surface of the third rotating ring 40, at this time, the third ball 48 abuts against the surface of the third rotating ring 40, causing the fourth slider 47 to be forced to compress the fifth return spring 46. Finally, the fourth slider 47 is received into the receiving groove 45. At this time, the driving motor 501 is started. The driving motor 501 drives the driving gear 5 at the output end to rotate. During the rotation of the driving gear 5, it drives the driving gear ring 6 to rotate through the meshing relationship. The rotation of the driving gear ring 6 drives the first rotating ring 7 to rotate together. When the first rotating ring 7 rotates, it drives the first clamping block 12 and the second horizontal shaft 44 to rotate synchronously, causing the second horizontal shaft 44 to move circumferentially along the outer wall of the third rotating ring 40 and finally move to the arc-shaped chute 4001 opened on the outer wall of the third rotating ring 40. At this time, the fifth return spring 46 rebounds and drives the fourth slider 47 to slide outwards along the receiving groove 45, causing the third ball 48 to enter the arc-shaped chute 4001. And as the rotation continues, when the third ball 48 slides to the end of the arc-shaped chute 4001, the continuous circumferential sliding will drive the entire third rotating ring 40 to rotate. At this time, the synchronous rotation of the third rotating ring 40 and the first clamping block 12 will drive the second extension pipe fitting 43 and the first extension pipe fitting 30 to rotate synchronously, facilitating subsequent welding operations; As the two pipe fittings rotate synchronously, the second balls 37 abutting against the joints of the two pipe fittings will continuously roll, causing the flux powder on the inner wall of the moving ring 36 to continuously fall on the joints of the two pipes through the annular grooves 38 opened on the outer walls of the second balls 37. It should be noted that the rotation directions of the first extension pipe fitting 30 and the second extension pipe fitting 43 need to ensure that the flux first falls on the joint. As the rotation continues, the electric welding gun 32 will then abut against the flux that has fallen on the joint. At this time, as the rotation continues, only by starting the electric welding gun 32 can the joint of the first extension pipe fitting 30 and the second extension pipe fitting 43 that is already covered with flux be welded, and the welding of the inner and outer walls of the joint of the first extension pipe fitting 30 and the second extension pipe fitting 43 is carried out synchronously; And since the inner wall of the guiding groove 14 is provided with a plurality of evenly distributed arc-shaped bumps 15, and the arc-shaped bumps 15 are arranged in a hemispherical shape, when the first horizontal axis 26 slides along the guiding groove 14, the first ball 27 at the end of the first horizontal axis 26 continuously contacts the arc-shaped bumps 15 during the sliding process, prompting the first ball 27 and the first horizontal axis 26 to contact the hemispherical surface of the arc-shaped bumps 15 and move away from the guiding groove 14. The movement of the first horizontal axis 26 drives the first fixing frame 25 to move together. The first fixing frame 25 drives the third slider 21 to be horizontally stressed, prompting the third slider 21 to drive the second guiding rod 20 and the sliding frame 19 to be horizontally stressed, and prompting the sliding frame 19 to slide along the outer wall of the third guiding rod 23 and compress the third return spring 24. When the first ball 27 slides past a single arc-shaped bump 15, the third return spring 24 resets and drives the sliding frame 19 to reset. The sliding frame 19 drives the third slider 21 and the first fixing frame 25 to reset. The first fixing frame 25 drives the first horizontal axis 26 and the first ball 27 to reset, causing the first horizontal axis 26 to closely adhere to the inner wall of the guiding groove 14 again to maintain sliding. Since there are a plurality of arc-shaped bumps 15, in this way, the sliding frame 19 will reciprocate left and right. The left and right reciprocating movement of the sliding frame 19 will drive the second fixing frame 28 and the third fixing frame 29 to reciprocate left and right in small amplitudes. The left and right small-amplitude movement of the second fixing frame 28 and the third fixing frame 29 will cause the flux to drop in a curved shape, and will prompt the welding of the electric welding gun 32 at the joint to be in a wavy curved path for welding, making the welding more uniform.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0039] The above is only the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
