The electric gripper also has a T-shaped limit block. A transverse guide rail is installed on the workbench, and a plurality of adjustment seats are slidably connected to the transverse guide rail. A positioning seat is installed on the adjustment seat. The positioning seat has a placement groove for placing the gasket, and the positioning seat also has a placement notch for placing the screw rod. A locking member is also threadedly connected to the adjustment seat.

[0005] A vertical guide rail is also installed on the vertical plate, a slider is slidably connected to the vertical guide rail, and the slider is connected to the movable seat.

[0006] The locking member is a hand-tightening screw.

[0009] Compared with the prior art, the auxiliary positioning device for the welding of a screw rod with multiple sections of threads of the present utility model has the following advantages:

[0010] In the present utility model, the spacer on the screw can be positioned by the positioning seat, so that it can be quickly adjusted to the required position. The end of the screw is abutted against the T-shaped limit block. After the spacer and the screw are preliminarily welded manually with a welding torch, the bolt is clamped by the electric gripper, and then the bolt is lifted upward by the lifting cylinder and disengaged from the positioning seat. The spacer and the screw are welded again manually with a welding torch. During the welding, the screw can be rotated by a corresponding angle according to needs by using the rotary cylinder, so that the welding operation of the screw with multiple threads can be conveniently carried out, and the positioning is convenient.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0016] Such as Figure 1 - Figure 2As shown in the figure, the auxiliary positioning device for welding a screw with multiple sections of threads includes a workbench 14. A vertical plate 3 is installed on the workbench 14, and a lifting cylinder 4 is installed on the vertical plate 3. The end of the piston rod of the lifting cylinder 4 is connected to a movable seat 5. A rotary cylinder 6 is installed on the movable seat 5. In this embodiment, the rotary cylinder 6 is an existing product and can rotate 90 degrees each time. An electric gripper 7 is installed on the rotating table of the rotary cylinder 6, and the gripper arm of the electric gripper 7 can clamp the end of the screw. The electric gripper 7 also has a T-shaped limit block 15. A transverse guide rail 12 is installed on the workbench 14, and a number of adjustment seats 11 are slidably connected to the transverse guide rail 12. A positioning seat 10 is installed on the adjustment seat 11. The positioning seat 10 has a placement groove 10b for placing gaskets, and the positioning seat 10 also has a placement notch 10a for placing the screw. With this structure, after the position of the positioning seat 10 is adjusted, the gasket threaded on the screw is placed into the corresponding placement groove 10b of the positioning seat 10, so that the end of the screw abuts against the T-shaped limit block 15. A locking member 9 is also threadedly connected to the adjustment seat 11. Specifically, the locking member 9 is a hand-tightening screw.

[0017] A vertical guide rail 2 is also installed on the vertical plate 3, and a slider 8 is slidably connected to the vertical guide rail 2. The slider 8 is connected to the movable seat 5.
