[0002] Alloy pipes are a type of seamless steel pipes. Alloy pipes are divided into seamless pipes for structural use and high-pressure heat-resistant alloy pipes. The main differences lie in their production standards and industries. Annealing and tempering are carried out on alloy pipes to change their mechanical properties to meet the required processing conditions. Their performance is more variable and has a higher utilization value than ordinary seamless steel pipes. In the chemical composition of alloy pipes, Cr is relatively abundant, with properties of high temperature resistance, low temperature resistance, and corrosion resistance. During the processing of alloy pipes, a welding tightening and positioning device is required.

[0027] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, A welding clamping and positioning device, comprising an operator's table 1 and a support frame 2.

Between the two electric telescopic rods 4, an electric slide table 5 is fixedly installed. At the bottom of the electric slide table 5, a welding head 6 is movably installed. On the top of the operator's table 1, a positioning structure 7 is arranged.

On the left side of the left electric telescopic rod 4, a motor 701 is fixedly installed. At the output shaft of the motor 701, a driving rod 702 is fixedly installed. On the outer surface of the driving rod 702, two driving seats 703 are movably installed. On the top of the driving seat 703, a mounting plate 704 is fixedly installed. On one adjacent side of the two mounting plates 704, fixing blocks 705 are fixedly installed. On one adjacent side of the two fixing blocks 705, first mounting seats 706 are fixedly installed.

[0028] By setting the positioning structure 7, the set motor 701 can be used to drive the driving rod 702 to rotate under the cooperation of two first bearings. While the driving rod 702 is rotating, since the driving rod 702 is movably connected to the two driving seats 703 and the external threads on the outer wall of the driving rod 702 are symmetrically arranged left and right, the two driving seats 703 can be driven to move in opposite or relative directions, so that the corresponding two mounting plates 704 move in opposite or relative directions at the same time, and then the components fixed on the mounting plates 704 can be driven to displace.

While the driving rod 702 rotates, since the driving rod 702 is movably connected to two driving seats 703 and the external threads on the outer wall of the driving rod 702 are symmetrically arranged on the left and right, the two driving seats 703 can be driven to move relatively or in opposite directions, so that the corresponding two mounting plates 704 move relatively or in opposite directions at the same time, and then the components fixed on the mounting plates 704 can be driven to displace. By setting the first mounting seat 706 and the second mounting seat 707, the adjusting assembly 708 is supported. By rotating the handle, the corresponding screw rod 7081 can be driven to rotate under the cooperation of the second bearing. While the screw rod 7081 rotates, the nut sleeve 7082 on its outer surface is driven to move upward or downward, and then the connecting arm 7083 moves with the movement of the nut sleeve 7082, and then the two corresponding upper clamping blocks 709 are driven to move upward or downward, so that alloy pipes of different sizes can be better fixed, the positioning is more accurate, and while it is convenient to fix alloy pipes of different sizes, the general performance of the device is greatly enhanced.

[0030] Moreover, by setting the lifting structure 3 and starting the air cylinder 301 to drive the piston rod to perform piston motion, the support column 302 can be driven to move upward or downward under the cooperation of the through hole, so as to drive the operating table 1 to adjust the height position, which can adapt to operators of different heights to work, and the applicable range is improved to a certain extent. By setting the electric telescopic rod 4 and the electric slide table 5, welding work can be carried out on alloy pipes of different sizes and different positions of the alloy pipes.
