Meanwhile, the second driving member 334 pushes the second mounting plate 3323 to slide along the slide rail 31 toward the direction close to the second supporting plate 331 through the second sliding block 3322, so as to drive the second push rod 3321 to approach the end piece 61 to abut against the end of the end piece 61 away from the tube 62. The motor 3224b operates to drive the synchronizing gear 3224a to rotate through the transmission chain 3224c, and then drive the first push rod 3221 to rotate, so as to drive the end piece 61 and the pipe 62 to rotate, and therefore, the periphery of the joint of the end piece 61 and the pipe 62 can be precisely welded. After the welding is completed, the first driving member 324 pulls the first mounting plate 3223 to slide along the slide rail 31 to a direction away from the first supporting plate 321 through the first slider 3222, and further drives the first push rod 3221 to move to a direction away from the tube 62, so as to separate from the welded tube 62. Meanwhile, the second driving member 334 pulls the second mounting plate 3323 to slide along the slide rail 31 and the direction away from the second support plate 331 through the second sliding block 3322, and then drives the second push rod 3321 to move in the direction away from the end piece 61, so as to separate from the end piece 61 after the welding is completed, and further loosen the end piece 61 and the pipe 62 after the welding is completed. Through setting up with slide rail 31 assorted second slider 3322, stabilize the direction to second mounting panel 3323, avoid second mounting panel 3323 motion in-process offset and influence the motion of second ejector pin 3321.

In some embodiments, referring to fig. 2 and fig. 4 again, a protrusion 3321a is disposed at an end of the second supporting rod 3321 away from the second mounting plate 3323, and the protrusion 3321a abuts against an end of the end piece 61 away from the tube 62, so that the end piece 61 and the tube 62 can be tightly attached to each other without shielding the end piece 61, thereby preventing the welding effect from being affected.

In an embodiment of the present invention, a welding apparatus is further provided, which includes a welding assembly (not shown), a blanking control assembly 4 and the welding fixture 100, please refer to fig. 1 to 5 again, wherein the blanking control assembly 4 is used for blanking the end piece 61. The blanking control assembly 4 comprises a guide piece 41, an elastic blocking piece 42 and a lower pressing piece 43, wherein a material passing channel 411 is formed in the guide piece 41, and an outlet of the material passing channel 411 is positioned above the transfer device 2; the elastic blocking member 42 comprises a fixed connecting block 421 and a torsion spring leaf 422 which are connected with each other, the fixed connecting block 421 is connected to the guiding member 41, and one end of the torsion spring leaf 422 departing from the fixed connecting block 421 extends into the material passing channel 411; the lower pressing member 43 is connected to the base plate 1 and to the guide member 41, and a part of the lower pressing member 43 protrudes into the material passing channel 411.

The welding equipment further comprises a pipe control cylinder 5, one end of the pipe control cylinder 5 is connected with a pipe storage device (not shown), and under the action of the pipe control cylinder 5, the pipe 62 in the pipe storage device can only fall one to the transfer device 2 at a time.

The end piece 61 falls into the material passing channel 411 by an end piece storage device (not shown), and is blocked in the material passing channel 411 by one end of the torsion spring leaf 422 departing from the fixed connecting block 421. The lower pressing member 43 may be controlled by a cylinder, or may be implemented in other ways, which are not limited in particular. The pressing piece 43 stretches into the material passing channel 411 to press down the end piece 61, and under the pressure action of the pressing piece 43, the torsion spring elastic piece 422 is compressed, so that the end piece 61 can smoothly fall to the conveying device 2 through the material passing channel 411 and an outlet of the material passing channel 411, the torsion spring elastic piece 422 withdraws from the material passing channel 411 under the elastic action of the torsion spring of the pressing piece 43, the initial state is recovered, the end piece 61 is further blocked, and the end piece 61 is prevented from falling completely. Meanwhile, the pipe control cylinder 5 controls the pipe 62 to fall to the moving device 2, and transfers the end piece 61 and the pipe 62 to a position between the first push rod 3221 and the second push rod 3321 through the moving device 2, and then tightly pushes up through the first push rod 3221 and the second push rod 3321 and is welded through the welding equipment.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
