[0023] Reference Figure 1-Figure 3The positioning mechanism includes a mounting plate 12 and an assembly component. The mounting plate 12 is arranged on the outside of the support frame 1 as a mounting base for components such as the motor 16 and the clamping block 19, providing a fixed mounting position for these components to ensure that their relative positions are stable during operation. A motor 16 is installed on one side of the mounting plate 12 as a power source. The output power rotates the rotating block 17, thereby driving the clamping block 19 to clamp or release, providing power support for the positioning mechanism. The output end of the motor 16 is fixedly connected to the rotating block 17, and the outer side of the rotating block 17 rotates. There are two connecting plates 18 in the dynamic connection, which connect the rotating block 17 and the clamping block 19, converting the rotation of the rotating block 17 into the linear sliding of the clamping block 19, playing the role of power transmission and motion conversion. The outer side of the mounting plate 12 is slidably connected to two clamping blocks 19. The outer side of the clamping block 19 is provided with an anti-slip pad 20 to increase the friction between the clamping block 19 and the steel pipe, avoiding the sliding phenomenon of the steel pipe under the clamping force, ensuring that the steel pipe is firmly clamped and fixed. A guide groove 21 is provided inside the mounting plate 12 to provide a sliding guide for the limit block 22 to ensure that the clamping block 19 is During the movement, the linear movement is carried out in a predetermined direction to ensure the movement accuracy of the clamping block 19. The inner side of the guide groove 21 is slidably connected to the limit block 22, which is fixedly connected to the clamping block 19 and moves together with the clamping block 19. By sliding in the guide groove 21, the movement of the clamping block 19 is limited to prevent the clamping block 19 from falling off. The outer side of the limit block 22 is fixedly connected to the outer side of the clamping block 19, and one end of the connecting plate 18 is rotatably connected to the outer side of the clamping block 19. The assembly component includes a U-shaped plate 13, which serves as the installation base of the assembly block 14 and is fixed to the outer side of the support frame 1 , providing support and connection for the entire assembly component, the outer side of the U-shaped plate 13 is fixedly connected to the outer side of the support frame 1, the top of the U-shaped plate 13 is fixedly connected to two assembly blocks 14, the top of the assembly block 14 is rotatably connected to a rotating piece 15, the outer side of the assembly block 14 is engaged with the inner side of the mounting plate 12, the outer side of the rotating piece 15 is in contact with the outer side of the mounting plate 12, the top of the rack plate 5 is meshed with the outer side of the gear 6, one end of the L-shaped rod 10 is fixedly connected to one end of the rack plate 5, and one end of the electric push rod 23 is fixedly connected to the outer side of the sliding sleeve 3.

[0024] Working principle: First, the steel pipe can be placed in the middle of the two clamping blocks 19, and then the motor 16 is started. Under the drive of the motor 16, the rotating block 17 will drive the two connecting plates 18 to rotate. Under the traction force of the connecting plate 18, the two clamping blocks 19 will approach each other to clamp the steel pipe, and rotate the rotating piece 15 to separate it from the outside of the mounting plate 12. The mounting plate 12 can be removed from the outside of the assembly block 14, and different specifications of clamps can be replaced according to actual needs.

[0025] In addition, when the steel pipe is clamped by the clamping block 19, the two electric push rods 23 can be started to drive the sliding sleeve 3 to move, so that the two clamping claws 7 can clamp the outside of the steel pipe. After releasing the clamping block 19, the electric push rod 1 8 is started to drive the movable frame 9 to move, which can make the L-shaped rod 10 drive the rack plate 5 to move, and then let the gear 6 drive the clamping claw 7 to rotate. In this way, the steel pipe can freely adjust the welding surface, making the operation during the processing more flexible and convenient, and greatly improving work efficiency.
