The pulley three 12 is in close contact with the inclined block 13. The inclined block 13 moves in the vertical direction to support and position the pipe. When the pulleys 9 on the two movable frames 8 are close to each other, the pipe between the two movable frames 8 can be automatically positioned so that its end is kept flush with the fixed on the chuck 24. For automatic welding, the fixed seat 2 moves on the upper surface of the mounting seat 1 to abut against the end of the pipe, and pushes the pipe located between the two movable frames 8 to move toward the end of the pipe on the chuck 24, so that the two ends of the pipes are aligned and the two pipes are in close contact, and the welding gun on the mounting frame 5 is moved in the vertical direction to weld the pipe.

Combining Embodiment 1 and Embodiment 2

By setting the positioning mechanism, the two pipes to be welded can be automatically positioned. When the pulleys 9 on the movable frame 8 are close to each other, the pipe located between the two movable frames 8 is automatically positioned so that its end is kept flush with the fixed on the chuck 24. The movement of the fixed seat 2 cooperates with the positioning seat 3 to limit the ends of the two pipes. At the same time, during the positioning process, it can be ensured that the two welded pipes can rotate freely to achieve full welding. The positions of the mounting frame 1 5 and the mounting frame 2 7 can be freely switched to facilitate full grinding. The equipment can automatically position, move and weld pipes, and has automatic switching and grinding functions, which greatly improves production efficiency and product quality. The equipment can adjust the position and size of the mechanism according to the specifications and requirements of different pipes to achieve welding and grinding of a variety of different pipes, and has strong versatility and flexibility.

As shown in Figures 1 to 6, the working process and principle of the present invention are as follows:

Step 1, fix the pipe by the chuck 24 on the positioning seat 3, place another pipe to be welded between the two movable frames 8, start the electric push rod 15, make the two movable frames 8 close to one end of the two pulleys 9, and cooperate with the pulley 3 12 on the inclined block 13, so as to realize the rapid positioning of the pipe, and automatically position the pipe between the two movable frames 8, so that its end is flush with the pipe fixed on the chuck 24, which is convenient for automatic welding, start the motor 3, so that the screw 31 can be rotated, so that the fixing seat 2 can be moved as a whole on the mounting seat 1, so as to push the pipe to fit and fix with another pipe, and push the pipe between the two movable frames 8 to move toward the pipe end on the chuck 24, so that the two pipe ends are aligned and the two pipes are in close contact;

Step 2, the mounting seat 24 moves along the axial direction of the pipe on the mounting seat 1, and then is fixed in position by bolts, so that the welding gun on the mounting frame 15 is located at the pipe connection for welding operation, the motor 2 drives the gear 28 to rotate, and the pulley 29 fixedly connected to the gear 28 drives the pulley 1 26 on the fixed seat 2 to rotate through the transmission belt 27. At the same time, under the action of the spline shaft 25, the chuck 24 on the positioning seat 3 rotates synchronously with the pulley 1 26, and the two pipes welded between the fixed seat 2 and the positioning seat 3 rotate at the same time, which can make the welding gun on the mounting frame 15 automatically weld along the pipe connection. When the welding is completed, the mounting frame 15 is switched away from the pipe. When the motor 16 on the outer wall of the mounting frame 27 is started, one of the transmission rollers 23 is driven to rotate by the motor 16, driving the emery cloth 17 to rotate, so that the emery cloth 17 moves quickly, and contacts the welding position through the emery cloth 17, and the pipe welding position is polished.
