[0029] Embodiment 1:

[0030] As Figures 1 to 3 shown, a training operation fixing tooling for improving welder skills includes a support column, a base 3, and a connecting plate 4. The support column includes an outer column 1 and an inner column 2. The outer column 1 is preferably a hollow column structure with openings at both ends. Both the inner column 2 and the outer column 1 are column structures in the shape of a cube. The outer column 1 is sleeved outside the inner column 2. An elevating adjustment mechanism is provided on the outer column 1. The elevating adjustment mechanism includes a rotating handwheel 5 and an elevating drive assembly. The elevating drive assembly can adopt a screw jack. Specifically, it can adopt the SWL worm gear and worm electric screw jack produced by Jiangsu Maishi Transmission Technology Co., Ltd. The rotating handwheel 5 is connected to the power input end of the screw jack. The power output end (screw) of the elevating drive assembly is connected to the inner column 2. Rotating the rotating handwheel 5 can drive the screw of the screw jack to elevate, thereby driving the inner column 2 to move up and down inside the outer column 1. A support flange can be provided at the upper end of the screw of the screw jack to provide support under the inner column 2 by using the flange. A connecting plate 4 is fixedly connected to the end of the inner column 2 away from the screw, and the connecting plate 4 is connected to the obstacle training operation mechanism 14, which can be elevated in the height range of 80 - 160 cm, suitable for operators of different heights.

[0031] Since there is a certain gap between the inner column 2 and the outer column 1, in order to improve the stability of the tooling during the training of welders, a plurality of locking bolts 7 are provided on the outer column 1. For example, 4 are provided, respectively located on the four side walls of the outer column 1. Each locking bolt 7 penetrates the side wall of the outer column 1. When the inner column 2 stops elevating and the position is determined, tighten each locking bolt 7, thereby holding and fixing the inner column 2 outside the inner column 2 to lock it, preventing the tooling from shaking during use.

[0032] During long-term use, the screw jack may need to be repaired, lubricated or replaced.

A groove is opened in the middle of the fixed groove plate 8, and the groove is adapted to the outer diameter of the outer column 1. The fixed groove plate 8 and the base 3 are connected by connecting bolts. The outer column 1 is clamped in the groove in the middle of the fixed groove plate 8, and the screw jack is connected to the fixed groove plate 8 inside the outer column 1.

[0033] When disassembly and assembly are required, the fixed groove plate 8 is detached from the base 3, then the fixed groove plate 8 is disassembled from the screw jack, and then the screw jack is taken out from the outer column 1. This setting facilitates the installation, disassembly and maintenance of the screw jack, and also facilitates the quick disassembly and assembly of the outer column 1 and the bottom plate.

[0034] Embodiment 2:

[0035] During welding training, it is often necessary to weld steel plates at different positions.

The double-headed bolt 1107 can pass through the through slot 1106 and through the groove 12, and then be clamped in the groove 12. In this way, the pipeline assembly mechanism 11 can be rotated along the connecting plate 4 and clamped and fixed in the angular spaces of 0°, 45°, and 90°. This setting can adjust the spatial position of the pipeline practice specimen and realize the welding function at different spatial welding positions.

[0038] The obstacle training operation mechanism can also be connected to the connecting plate 4 in the same way, and the position of the simulated obstacle on the obstacle training operation mechanism can be adjusted in the same way, which also plays the welding role at different spatial welding positions.

If the diameter of the pipeline is large, the pipeline wall is inserted between the clamping plate 1108 and the assembly fixing cylinder 1102 and fixed by the clamping bolt 1109. This embodiment can realize the quick fixation of pipeline practice specimens with a pipeline diameter of 13.7 mm - 219 mm, without leaving spot welding fixed welds, and greatly improves the service life of the assembly device.
