Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe welding, and particularly relates to a metal pipe welding positioning tooling. Background Art

[0002] Welding, also known as fusion welding, is a manufacturing process and technology for joining metals or other thermoplastic materials such as plastics by means of heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flames, electric arcs, lasers, electron beams, friction and ultrasonic waves, etc.

[0003] However, in the prior art, during the welding of metal pipes, it is often necessary to fix two metal pipes through two positioning devices and then move them closer to each other for welding. Manual control is often required, which may cause misalignment at the connection due to external forces during docking, affecting the welding accuracy. Moreover, during the welding process, the metal pipes need to be rotated for welding, which is time-consuming and laborious, and may also cause docking deviation during rotation, which will also affect the welding accuracy. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: a metal pipe welding positioning tooling, comprising: an operating table; an adjusting screw rod, the adjusting screw rod is rotatably connected to the top end of the operating table through a rotating shaft; a driving mechanism, the outer wall of the driving mechanism is fixedly connected to the outer wall of the operating table; a fixing mechanism, the outer wall of the fixing mechanism is rotatably connected to the outer wall of the driving mechanism; the fixing mechanism includes a rotating cylinder, a rotating ring is rotatably connected to the outer wall of the rotating cylinder, a toothed ring is rotatably connected to the outer wall of the rotating cylinder, a pushing screw rod is slidably connected to the inner wall of the rotating cylinder, and a clamping block is rotatably connected to the bottom end of the pushing screw rod.

[0005] Preferably, the rotating ring is meshed with the toothed ring, the toothed rings are annularly arranged along the central axis of the rotating cylinder, and the outer wall of the pushing screw rod is threadedly connected to the inner wall of the toothed ring. By rotating the rotating ring, the toothed ring meshed with the rotating ring rotates. As the toothed ring rotates, the pushing screw rod connected by threads moves downward on the rotating cylinder.

[0006] Preferably, the driving mechanism includes a motor. The output end of the motor is fixedly connected to a rotating rod. Both ends of the rotating rod are slidably connected to sliding cylinders. The inner wall of the sliding cylinder is provided with clamping blocks. The wall of the rotating rod is provided with limiting grooves. The outer wall of the sliding cylinder is rotatably connected to a connecting block. The rotating rod is rotatably connected to the outer wall of the operating table through a rotating shaft. The bottom end of the motor is fixedly connected to the outer wall of the operating table. The inner wall of the sliding cylinder is slidably connected to the outer wall of the rotating rod. The outer wall of the clamping block is slidably connected to the inner wall of the limiting groove. The motor drives the fixedly connected rotating rod to rotate. Through the clamping connection between the clamping block and the limiting groove, when the rotating rod rotates, it drives the sliding cylinder fixedly connected to the clamping block to rotate on the connecting block.

[0007] Preferably, the outer wall of the connecting block is slidably connected to the inner wall of the operating table. The inner wall of the connecting block is threadedly connected to the outer wall of the adjusting screw rod. Rotating the adjusting screw rod causes the adjusting screw rod to drive the connecting block threadedly connected to it to move on the operating table.

[0008] Preferably, the inner wall of the connecting block is rotatably connected to the outer wall of the rotating cylinder. A pulley group is provided on the outer walls of the rotating cylinder and the sliding cylinder. Through the connection of the pulley group, when the sliding cylinder rotates, it drives the rotating cylinder at the other end to rotate on the connecting block.

[0009] The beneficial effects of the present utility model are as follows:

[0010] 1. By setting the fixing mechanism in the present utility model, the screw rod moves downward on the rotating cylinder and drives the clamping block at the bottom to move until it contacts the steel pipe, thereby completing the fixation of the steel pipe. It can be fixed from the inside of metal pipe fittings with different diameters, achieving the purpose of fixing metal pipe fittings with different diameters, solving the problem that the existing positioning tooling cannot be applied to metal pipe fittings with different diameters. By rotating the adjusting screw rod, the connecting block moves on the operating table. As the connecting block moves, the steel pipes fixed at both ends move until the two steel pipes are in contact with each other, facilitating welding.

[0011] 2. By setting the driving mechanism in the present utility model, the rotating rod rotates to drive the sliding cylinder to rotate on the connecting block. Through the connection of the pulley group, when the sliding cylinder rotates, it drives the rotating cylinder at the other end to rotate on the connecting block, thereby driving the two fixed steel pipes to rotate. Thus, during the welding process, there is no need to rotate the steel pipes, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

By rotating the rotating ring 42, the toothed ring 43 meshing with the rotating ring 42 rotates. As the toothed ring 43 rotates, the threadedly connected pushing screw 44 moves downward on the inner wall of the rotating cylinder 41.

[0020] The driving mechanism 3 includes a motor 35. A rotating rod 36 is fixedly connected to the output end of the motor 35. Sliding cylinders 32 are slidably connected to both ends of the rotating rod 36. Clamping blocks 33 are provided on the inner wall of the sliding cylinders 32. A limiting groove 37 is provided in the wall of the rotating rod 36. A connecting block 31 is rotatably connected to the outer wall of the sliding cylinder 32. The rotating rod 36 is rotatably connected to the outer wall of the operating table 1 through a rotating shaft. The bottom end of the motor 35 is fixedly connected to the outer wall of the operating table 1. The inner wall of the sliding cylinder 32 is slidably connected to the outer wall of the rotating rod 36. The outer wall of the clamping block 33 is slidably connected to the inner wall of the limiting groove 37. The motor 35 drives the fixedly connected rotating rod 36 to rotate. Through the engagement of the clamping block 33 and the limiting groove 37, when the rotating rod 36 rotates, the sliding cylinder 32 fixedly connected to the clamping block 33 rotates on the connecting block 31.
