[0003] However, the following problems still exist in actual use:

[0004] During use, the existing welding equipment can only weld pipe fittings, and cannot mechanically realize the positioning and rotation welding of pipe fittings, so personnel are required to perform positioning and rotation welding. The positioning and rotation by personnel are inaccurate, and the rotation speed is uneven, which causes uneven welds, resulting in reduced accuracy of pipe welding, and inconvenient flexible adjustment, which increases the workload of operators and reduces their work efficiency. Summary of the invention

[0008] Preferably, an L-shaped block is fixedly connected to one side of the upper surface of the base plate, and a cylinder is fixedly installed on the inner upper surface of the L-shaped block.

[0009] Preferably, side grooves are provided on both sides of the inner groove, side blocks are rotatably connected inside the side grooves, and opposite sides of the side blocks are fixedly connected to two sides of the inner frame.

[0010] Preferably, the output shaft of the cylinder is fixedly connected to a carrying frame, and a welding head is connected to the carrying frame.

[0011] Preferably, the welding head is connected to an external welding source.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This pipe welding equipment is provided with a fixing mechanism. When fixing the pipe, the pipe is first placed in the middle position of the inner frame. At this time, the lower surface of the pipe contacts the surface of the sponge block on the upper surface of the top block set at the end of the connecting rod. Since the threaded rod is threadedly connected to the connecting frame, the threaded rod is rotated to make the threaded rod move downward on the connecting frame, and the top block set at the lower end of the threaded rod and the sponge block set on the top block move downward synchronously, so that the sponge block can contact the upper surface of the pipe and continuously apply pressure until it is tightly pressed against the pipe. According to the above steps, the required two groups of pipes to be welded are fixed on the two groups of fixing mechanisms respectively, and the distance between the ends of the two groups of pipes is controlled to complete the subsequent welding. The setting of this structure can effectively fix the two groups of pipes to be welded relatively, which is convenient for subsequent welding. At the same time, it can adapt to pipes of different diameters. When the two groups of pipes are fixed, the pipes can be in the same straight line by rotating the threaded rod by the same length.

[0014] This pipe welding equipment is provided with gear 1, gear 2 and a motor. After the pipes are butt-jointed, during welding, since the fixing mechanism is installed on the inner wall of the inner frame, and the inner wall of gear 1 is fixedly connected to the outer wall of the inner frame, the outer surface of gear 1 is meshed with the outer surface of gear 2, so that gear 2 is driven to rotate by the operation of the motor, and gear 2 drives gear 1 meshed with it to rotate synchronously, thereby prompting the fixing mechanism provided inside the inner frame to drive the pipes to rotate synchronously. At this time, the pipes can be welded by the welding head. The setting of this structure can effectively drive the pipes to rotate, and maintain their rotation speed and direction by machinery, so as to ensure the efficiency and aesthetics of subsequent welding, and avoid the situation where uneven welding points occur due to artificial rotation.

The pipe fitting is placed in the middle position of the inner frame 11. At this time, the lower surface of the pipe fitting contacts the surface of the sponge block 16 on the upper surface of the top block 15 set at the end of the connecting rod 21. Since the threaded rod 14 is threadedly connected to the connecting frame 13, the threaded rod 14 is rotated to make the threaded rod 14 move downward on the connecting frame 13, and the top block 15 set at the lower end of the threaded rod 14 and the sponge block 16 set on the top block 15 move downward synchronously, so that the sponge block 16 can contact the upper surface of the pipe fitting and continuously apply pressure, so that the connecting rod 21 squeezes the spring 23 and the damping rod 22 downward, and makes the spring 23 and the damping rod 22 reach the maximum compression coefficient position, at which time the pipe fitting can be pressed tightly. According to the above steps, the required two groups of pipe fittings to be welded are fixed on the two groups of fixing mechanisms 7 respectively, and the distance between the ends of the two groups of pipe fittings is controlled so that the ends of the pipe fittings can be butt-jointed.

[0022] See also Figure 1 and Figure 3 The outer surface of the inner frame 11 is fixedly connected with a gear 12, a notch 19 is provided on one side of the inner groove 8, and a gear 2 17 is rotatably connected inside the notch 19.

A motor 18 is installed on one side of the bearing block 6, and the output shaft of the motor 18 is fixedly connected with the middle part of one side of the gear 2 17. During welding, since the fixing mechanism 7 is installed on the inner wall of the inner frame 11, and the inner wall of the gear 12 is fixedly connected with the outer wall of the inner frame 11, the outer surface of the gear 12 is meshed with the outer surface of the gear 2 17, so that the gear 2 17 is driven to rotate by the work of the motor 18, and the gear 2 17 drives the meshing gear 12 to rotate synchronously, thereby prompting the fixing mechanism 7 set inside the inner frame 11 to drive the pipe fittings to rotate synchronously, and the pipe fittings can be welded at this time.

[0024] See also Figure 2 Side grooves 9 are provided on both sides of the inner groove 8, and side blocks 10 are rotatably connected inside the side grooves 9. The opposite sides of the side blocks 10 are fixedly connected to the two sides of the inner frame 11. When the inner frame 11 rotates, the side blocks 10 rotate synchronously inside the side grooves 9, thereby ensuring the stability of the inner frame 11 when rotating.

[0025] Working principle: when in use, first, when fixing the pipe fitting, first place the pipe fitting in the middle position of the inner frame 11. At this time, the lower surface of the pipe fitting contacts the surface of the sponge block 16 on the upper surface of the top block 15 set at the end of the connecting rod 21. Since the threaded rod 14 is threadedly connected to the connecting frame 13, the threaded rod 14 is rotated to make the threaded rod 14 move downward on the connecting frame 13, and the top block 15 set at the lower end of the threaded rod 14 and the sponge block 16 set on the top block 15 move downward synchronously, so that the sponge block 16 can contact the upper surface of the pipe fitting and continuously apply pressure so that the connecting rod 21 squeezes the spring 23 and the damping rod 22 downward, and makes the spring 23 and the damping rod 22 reach the maximum compression coefficient position, at which time the pipe fitting can be pressed tightly. According to the above steps, the two required groups of pipe fittings to be welded are fixed on the two groups of fixing mechanisms 7 respectively at the same time, and the distance between the ends of the two groups of pipe fittings is controlled so that the ends of the pipe fittings can be butt-jointed.

[0026] At this time, through the operation of the cylinder 3, the welding head 5 set on the output shaft of the cylinder 3 is suspended just above the butt end of the pipe fitting. During welding, since the fixing mechanism 7 is installed on the inner wall of the inner frame 11, and the inner wall of the gear 12 is fixedly connected to the outer wall of the inner frame 11, the outer surface of the gear 12 is meshed with the outer surface of the gear 2 17, so that the gear 2 17 is driven to rotate by the operation of the motor 18, and the gear 2 17 drives the meshed gear 12 to rotate synchronously, thereby prompting the fixing mechanism 7 set inside the inner frame 11 to drive the pipe fitting to rotate synchronously, and at this time, the pipe fittings can be welded by the welding head 5.
