The chuck 1 is used to clamp or tighten one end of the member A, and the straightening member 2 is used to tighten and straighten the member B. The vertical welding positioner of the utility model provides a stable support for a long rotating workpiece, eliminates or improves the shaking of the workpiece during the rotation process, and improves the welding quality and consistency.

[0041] like Figure 1 As shown, the chuck 1 may include, for example, a chuck body 11 supported to be rotatable, and the chuck body 11 is provided with a plurality of claws 12 evenly distributed around the middle of the chuck body 11, and the number of the claws 12 is generally 3 or 4, but the present patent is not limited thereto.

[0042] The clamping jaw 12 is movably connected to the chuck body 11 along the radial direction of the chuck body 11 to form a clamping position in the middle of the chuck body 11; the clamping jaw 12 can fix the workpiece by clamping the workpiece on the inner side toward the center of the chuck body 11, or by supporting the part on the outer side away from the center of the chuck body 11.

[0043] The straightening member 2 includes a tapered portion 21 having a large end and a small end that are relatively arranged, wherein the small end of the tapered portion 21 is opposite to the clamping position in the middle of the chuck body 11, so that the tapered portion 21 has an automatic centering function when tightening a rotating workpiece.

[0044] The welding gun clamping assembly 7 includes a clamping seat 75 for clamping the welding gun 15, so as to provide a stable support for the welding gun 15 during welding operation.

[0045] The tapered portion 21 can be extended or retracted toward the chuck 1 to clamp or release the workpiece.

[0046] Specifically, in some embodiments, the vertical welding positioner further includes a straightening drive device 3, the straightening drive device 3 includes a straightening rod 32, the straightening rod 32 is connected to the straightening member 2, and the straightening rod 32 is used to provide a force to push the straightening member 2 toward the chuck 1.

[0047] In this embodiment, the straightening drive device 3 is arranged along the up and down direction, wherein the lower end of the straightening rod 32 is connected to the large end of the tapered portion 21, and the straightening rod 32 and the straightening cylinder 31 are slidably connected up and down, thereby being able to adapt to the clamping needs of workpieces of different lengths.

[0048] During use, the claws 12 of the chuck 1 clamp or hold the component A to be welded, and at the same time, the tapered portion 21 is used to press the upper end of the component B, so that the component B and the welded portion of the component A are pressed against each other, forming a stable support for the welded components A and B. Then, the front end of the welding gun 15 is moved to the weld, and the welding machine is turned on while the chuck 1 is rotated to perform welding. The technical solution of this patent has high working efficiency and good product consistency.

[0049] In some embodiments, the vertical welding positioner further includes a chuck driving device 10, which includes a driving element 101 and a chuck transmission mechanism 102. The driving element 101 may be, for example, a motor, and the output end of the motor drives the chuck 1 to rotate through the chuck transmission mechanism 102. The chuck transmission mechanism 102 may be, for example, a belt transmission mechanism, a chain transmission mechanism, or a gear transmission mechanism.

[0050] In some embodiments, the righting drive device 3 further includes a righting cylinder 31, and the righting rod 32 is movably connected to the righting cylinder 31. The righting drive device 3 can be a cylinder or a hydraulic cylinder, or other structures that can be extended up and down, such as a combination of a lead screw and a lead screw lock nut.

[0051] In this embodiment, the straightening rod 32 and the straightening cylinder 31 are movably connected, so that they can move toward the workpiece to clamp the workpiece, and provide a force to keep the components A and B in contact with each other through air pressure or hydraulic pressure during welding. After welding is completed, the straightening rod 32 can be withdrawn with the tapered portion 21 to replace the workpiece.

[0052] In some embodiments, the righting drive device 3 also includes a limiting portion 33, which is connected to the righting rod 32. The limiting portion 33 is configured to move with the righting rod 32, and is limited when the righting rod 32 moves to a set position in a direction close to the clamping position.

[0053] For example, the limiting portion 33 includes a nut. When the straightening rod 32 moves downward to a set position, the nut is stuck at the upper end of the straightening cylinder 31 and cannot continue to move downward.

[0054] In this embodiment, the extending length of the straightening rod 32 can be limited and adjusted by the limiting portion 33 to meet the welding operation requirements of workpieces of different lengths.

[0055] In some embodiments, the vertical welding positioner includes a frame 9, a swing seat 13 and a swing drive device 14. The frame 9 can be fixed on the ground, for example.
