Description

Technical Field

[0001] This utility model relates to the field of metal pipe welding technology, and in particular to a metal pipe welding equipment. Background Technology

[0002] A pipeline is a system of pipes, pipe fittings, valves, and other components used to transport gases, liquids, or fluids containing solid particles. Typically, fluids are pressurized by blowers, compressors, pumps, and boilers, flowing from high-pressure areas to low-pressure areas within the pipeline. Alternatively, the fluid's own pressure or gravity can be used for transport. Pipelines have a wide range of applications, primarily in water supply, drainage, heating, gas supply, long-distance transport of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] In order to meet certain usage requirements, metal pipes need to be butt-welded using welding equipment. During the welding process, it is difficult to align the opposite ends of the two sets of pipes, which can easily lead to deviations and thus affect the quality of the welded pipes. Utility Model Content

[0004] The main purpose of this utility model is to provide a metal pipe welding equipment.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A metal pipe welding device includes a machine base. An adjustment assembly is installed inside the machine base. Mounting plates are fixed on both sides of the adjustment assembly. Three-jaw chucks are fixed on opposite sides of the two sets of mounting plates. A limiting mechanism is installed on one set of three-jaw chucks. The limiting mechanism includes a screw threadedly connected to the three-jaw chuck. An air passage is opened in the middle of the screw. One end of the screw is rotatably connected to a machine housing. An air bag is installed in the middle of the machine housing and is connected to the air passage. Multiple sets of limiting frames are equidistantly installed on the outside of the air bag. The limiting frames are slidably connected to the machine housing. A connection port is installed on the screw on the side away from the machine housing.

[0007] Preferably, the adjustment assembly includes a ball screw that is rotatably connected to the machine tool, and one end of the ball screw is connected to a drive motor.

[0008] Preferably, guide rods are symmetrically arranged on the outer side of the ball screw, and sliding seats are connected to both the ball screw and the guide rods, with the mounting plate fixed on the sliding seats.

[0009] Preferably, both sets of the three-jaw chucks are rotatably connected to the mounting plate, and a rotating motor is connected to the outside of the other set of the three-jaw chucks.

[0010] Preferably, a frame is fixed to one side of the top center of the machine base, and cylinders are symmetrically installed on the top of the frame.

[0011] Preferably, a piston rod is slidably connected inside the cylinder, and the piston rod passes through the frame.

[0012] Preferably, a fixing plate is connected to the bottom end of the piston rod, and a welding machine is fixed to the bottom end of the fixing plate.

[0013] Preferably, the screw passes through the mounting plate, and the screw is rotatably connected to the mounting plate.

[0014] The beneficial effects of this technology are:

[0015] By setting a limiting mechanism, when welding the pipes, the operator can rotate the screw inside the limiting mechanism according to the length of the pipes. The screw rotates along the three-jaw chuck, which moves the machine housing to the connection point of the two sets of pipes. After the movement is completed, it is connected to the external air supply pipe through the connection port. High-pressure gas enters the air bag through the connection port and the air passage. The air bag is inflated from a deflated state to an inflated state. The inflated air bag moves the limiting frame along the machine housing. The limiting frame supports the two sets of pipes inside, which enables the two sets of pipes to be quickly and accurately aligned, thereby ensuring the quality of the welded pipes.

[0022] like Figures 1-3 As shown, this embodiment provides a metal pipe welding device, including a machine base 1. An adjusting assembly 2 is installed inside the machine base 1. Mounting plates 3 are fixed to both sides of the adjusting assembly 2, and the mounting plates 3 can support three-jaw chucks 4. Three-jaw chucks 4 are fixed to opposite sides of the two sets of mounting plates 3, clamping the ends of two sets of pipes. A limiting mechanism 5 is installed on one set of three-jaw chucks 4. The limiting mechanism 5 includes a screw 501 threadedly connected to the three-jaw chuck 4. The screw 501 can adjust the position of the machine housing 503. An air passage 502 is opened in the middle of the screw 501, allowing high-pressure gas to be transported. Inside the airbag 504, one end of the screw 501 is rotatably connected to the housing 503. The housing 503 can guide the limiting frame 505. The airbag 504 is installed in the middle of the housing 503. After the airbag 504 is inflated, it can drive the limiting frame 505 to move. The airbag 504 is connected to the air passage 502. Multiple sets of limiting frames 505 are installed at equal intervals on the outside of the airbag 504. The limiting frame 505 can limit the two sets of pipes. The limiting frame 505 is slidably connected to the housing 503. A connection port 506 is installed on the side of the screw 501 away from the housing 503. The connection port 506 can be connected to an external air supply device.

[0023] like Figure 1 As shown, the adjustment component 2 includes a ball screw 201 that is rotatably connected to the machine base 1. One end of the ball screw 201 is connected to a drive motor 203, which facilitates the rotation of the ball screw 201 by the drive motor 203.

[0024] like Figure 1 As shown, guide rods 202 are symmetrically arranged on the outer side of the ball screw 201, and sliding seats 204 are connected to both the ball screw 201 and the guide rods 202. The mounting plate 3 is fixed on the sliding seat 204 and can drive the sliding seat 204 to move horizontally along the guide rods 202 during the rotation of the ball screw 201, thereby adjusting the position of the mounting plate 3.

[0025] like Figure 1 As shown, both sets of three-jaw chucks 4 are rotatably connected to the mounting plate 3, and a rotating motor 6 is connected to the outside of the other set of three-jaw chucks 4, so that one set of three-jaw chucks 4 can be rotated by the rotating motor 6.

[0026] like Figure 1 As shown, a frame 7 is fixed on one side of the top center of the machine base 1, and cylinders 8 are symmetrically installed on the top of the frame 7 to facilitate support of the cylinders 8 through the frame 7.

[0027] like Figure 1 As shown, a piston rod 9 is slidably connected inside the cylinder 8, and the piston rod 9 passes through the frame 7, enabling the cylinder 8 to drive the piston rod 9 to move.

[0028] like Figure 1 As shown, the bottom end of the piston rod 9 is connected to a fixing plate 10, and the bottom end of the fixing plate 10 is fixed with a welding machine 11, so that the piston rod 9 can drive the welding machine 11 to move up and down through the fixing plate 10.

[0029] like Figure 1 As shown, the screw 501 passes through the mounting plate 3 and is rotatably connected to the mounting plate 3, which facilitates the rotation of the screw 501 along the three-jaw chuck 4.

[0030] The working principle of this device is as follows: In practical use, the operator places the ends of two sets of pipes onto the three-jaw chucks 4. The two sets of three-jaw chucks 4 clamp the ends of the two sets of pipes. After clamping, the drive motor 203 in the adjusting assembly 2 drives the ball screw 201 to rotate. During the rotation of the ball screw 201, the sliding seat 204 moves horizontally along the guide rod 202, thereby adjusting the position of the mounting plate 3, so that the welded ends of the two sets of pipes abut against each other. After adjustment, the operator rotates the screw 501 in the limiting mechanism 5 according to the length of the pipes. The screw 501 rotates along the three-jaw chucks 4, causing the housing 503 to move to the connection point of the two sets of pipes. After the movement is completed, it is connected to the external air supply pipeline through the connection port 506. High-pressure gas enters the airbag 504 through the connection port 506 and the air passage 502. The airbag 504 is inflated from a deflated state to an inflated state. The inflated airbag 504 drives the limit frame 505 to move along the housing 503. The limit frame 505 supports the two sets of pipes inside, so that the two sets of pipes can be quickly and accurately aligned, thereby ensuring the quality of the pipes after welding. After the positioning is completed, the cylinder 8 at the top of the frame 7 drives the piston rod 9 to move. The piston rod 9 drives the welding machine 11 to move to the appropriate position to weld the pipes through the fixing plate 10. At the same time, the pipes can be rotated and welded by rotating the motor 6.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
