Its precise control capability helps to achieve a more precise and stable welding process, reduce vibration and deformation during welding, thereby improving welding quality and reducing the incidence of weld defects.

[0003] In the existing welding positioner, the angle of the welding block is adjusted during welding to meet the requirements on welding accuracy. The existing flip welding positioner is not comprehensive enough in adjusting the angle, resulting in low welding efficiency and inconvenience in use.

[0004] Therefore, the utility model provides a multi-angle flip welding positioner to solve the above problems. Utility Model Content

A limiting plate and a first motor are fixedly installed on the top of the workbench. The inner side surfaces of the limiting plates are fixedly connected with fixing blocks. The output end of the first motor passes through one side of the limiting plate and is fixedly connected with a bidirectional screw.

[0013] Furthermore, the bidirectional screw is caused to rotate between the left and right fixing blocks by starting the first motor.

The upper and lower heights are adjusted by sliding the clamping plate and fixed with bolts, so that the welding block is clamped up and down.

[0016] According to the above technical solution, a support is fixedly connected to the inner wall of the semicircular concave plate, and the inner sides of the front and rear supports are rotatably connected to connecting blocks. The front and rear connecting blocks are fixedly connected to the bottom of the workbench, and a rotating shaft is fixedly connected between the front and rear connecting blocks. The outer end of the rotating shaft passes through the connecting block and the support and is fixedly connected to a gear, and the gear and the rack are engaged with each other.

[0017] Furthermore, the engagement of the rack and the gear drives the rotating shaft to rotate, thereby causing the workbench to tilt left and right.

[0018] Beneficial effects

[0019] The utility model provides a multi-angle flip welding positioner. Compared with the existing technology, it has the following advantages:

[0020] 1. This multi-angle flip welding positioner starts the self-locking motor and hydraulic rod, so that the pin wheel and rack respectively drive the cylindrical clamping block and the gear to rotate, thereby rotating the semicircular concave plate, and the rotating shaft drives the connecting block to rotate so that the workbench rotates, realizing multi-directional and comprehensive angle adjustment of the welding block before welding.

[0021] 2. This multi-angle flip welding positioner starts the first motor to rotate the bidirectional screw to drive the slider to move left and right, clamping the welding block left and right. Then the first motor is turned off and the clamping plate is pulled to slide upward inside the slide. When it rises to a suitable height, the bolts on both sides are tightened to fix the clamping plate in one place, thereby clamping the welding block up and down and fixing the welding block before welding.

The output end of the hydraulic rod 31 is fixedly connected to a rack 32. A support 33 is fixedly connected to the inner wall of the semicircular concave plate 21. The inner sides of the front and rear supports 33 are rotatably connected to connecting blocks 34. The front and rear connecting blocks 34 are fixedly connected to the bottom of the workbench 41.

The outer end of the rotating shaft 35 passes through the connecting block 34 and the support 33 and is fixedly connected to a gear 36. The gear 36 and the rack 32 are meshed with each other.

[0033] In this embodiment, when the device is rotated in the front and rear directions, the self-locking motor 24 is started, and the self-locking motor 24 drives the pin wheel 25 to rotate. Since the pin wheel 25 is engaged with the cylindrical block 23, the semicircular concave plate 21 is rotated, and a rotating plate 22 is rotatably connected between the semicircular concave plate 21 and the connecting rod 12, which supports the semicircular concave plate 21 while ensuring that its rotation is not constrained; when the device is rotated in the left and right directions, the hydraulic rod 31 is started, and the output end of the hydraulic rod 31 drives the rack 32 to move left and right.
