Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to an automated welding system for steel pipe assemblies. Background Technology

[0002] The steel pipe is a hollow material with an outer wall made of a single piece of steel pressed and welded together. Pumps or valves can be installed at the joints to transport powders, liquids and gases. It can also be built into support structures of different shapes for support and reinforcement. At present, welding equipment is still needed to facilitate the extension of the steel pipe or the adjustment of the joint orientation.

[0003] Ordinary welding equipment often requires manual labor or clamps to separate and fix the steel pipes. It lacks the ability to roll and makes it difficult to perform uniform welding treatment at the pipe ends. At this time, it is necessary to manually adjust the orientation of the steel pipe so that welding treatment can be carried out around the pipe ends, which is both dangerous and easy to cause the pipe ends to be misaligned.

[0004] Now, a novel automated welding system for steel pipe assemblies is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automated welding system for steel pipe assemblies to solve the problem of inconvenient turning of steel pipes mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated welding system for steel pipe assemblies, comprising a base plate and a left sleeve, wherein a left sleeve is fixed to the left side of the top of the base plate, and a right sleeve is fixed to the right side of the top of the base plate; channels are laterally arranged at the center of the interior of the left and right sleeves respectively; a support plate is fixed to the center of the rear of the top of the base plate, and a top plate is installed above the support plate; a cylinder is installed on the top of the top plate, and a welding torch is fixed to the bottom of the piston rod of the cylinder; the left sleeve and... The right sleeve has steel pipes inserted horizontally inside. The left sleeve has cavities at the top and bottom, and a rotating shaft is installed horizontally between the cavities. Rollers are fixed on both sides of the outside of the rotating shaft. A motor is installed at the upper left corner of the outside of the left sleeve and the upper right corner of the outside of the right sleeve. The left and right sleeves have slots at the top and bottom of the center of the inside, and gears are movably connected between the two sides of the slots. Gear rings are sleeved between the outside of the gears, and tooth blocks are fixed around the inner wall of the gear rings.

[0007] As a further technical solution of this utility model, the cylinder can guide the piston rod to vertically raise and lower the welding gun, and the welding gun can approach the splice of the steel pipes on both sides for welding.

[0008] As a further technical solution of this utility model, the right side of the output end of the motor is fixedly connected to the top rotating shaft, and the gears are symmetrically meshed inside the gear ring at the top and bottom.

[0009] As a further technical solution of this utility model, the rollers and gears rotate in the same direction, and the rollers are symmetrically fixed on both sides outside the rotating shaft.

[0010] As a further technical solution of this utility model, an air hole is provided at the upper left corner of the outside of the roller, and an air pump is inserted and fixed in the air hole. An air inflation chamber is provided inside the roller.

[0011] As a further technical solution of this utility model, a slide is provided between the upper and lower ends of the front end of the support plate, and a sleeve block is movably connected in the slide.

[0015] (1) A left sleeve is fixed on the left side of the top of the substrate and a right sleeve is fixed on the right side of the top of the substrate. Steel pipes are inserted into the left and right sleeves on both sides of the substrate. Then, two sets of motors are started to rotate the upper and lower shafts inside the corresponding left and right sleeves. Under the rotation of the gear at the center, the gear ring sleeved on the outside is engaged with the gear meshing gear block to force the two shafts to rotate together.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, a right sleeve 5 is fixed on the right side of the top of the substrate 1. Steel pipes 3 are inserted into the left sleeve 2 and right sleeve 5 on both sides of the substrate 1, respectively. Then, two sets of motors 4 are started, and the upper and lower rotating shafts 15 are rotated inside the corresponding left sleeve 2 and right sleeve 5. Under the rotation of the gear 13 at the center, the gear ring 6 sleeved on the outside is engaged with the gear 13 meshing with the tooth block 14, forcing the two rotating shafts 15 to rotate together, and then pushing the steel pipe 3 to rotate in the channel 17.

[0027] An air hole 25 is provided on the upper left corner of the outside of the roller 10, and an air pump 23 is inserted and fixed in the air hole 25. An inflation chamber 24 is provided inside the roller 10.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, whenever the steel pipe 3 is inserted laterally into the channel 17, the roller 10 connected to the rotating shaft 15 in the cavity 16 is made of hollow rubber material.

[0032] Working Principle: When this utility model is in use, whenever the steel pipe 3 is inserted laterally into the channel 17, the roller 10 connected to the rotating shaft 15 in the cavity 16 is made of hollow rubber material. Gas can be injected into the inflation chamber 24 of the roller 10 through the side air pump 23, which can adjust the degree of bulging of the roller 10 and facilitate the adjustment of the diameter of the roller 10 when it contacts the steel pipe 3. Different sizes of steel pipes 3 can be clamped. The steel pipe 3 is inserted into the left sleeve 2 and right sleeve 5 on both sides of the base plate 1, respectively. Then, the two sets of motors 4 are started, and the rotating shaft 15 at the upper and lower positions inside the corresponding left sleeve 2 and right sleeve 5 rotates. Under the rotation of the gear 13 at the center, the outer sleeve is engaged. The side gear ring 6, with gear 13 meshing with gear block 14, forces the two rotating shafts 15 to rotate together, and then pushes the steel pipe 3 to rotate in the channel 17. After the welding torch 9 sinks, it can perform thorough welding treatment on the joint of the steel pipe 3. Finally, the sleeve block 21 is vertically raised and lowered in the slide 12 at the front end of the support plate 11. The limiting piece 19 is also attached to the surface of the positioning hole 18. The bolt 20 is rotated in the screw hole 22 until the rear end of the bolt 20 is embedded in the positioning hole 18, so that the hollow sleeve block 21 is attached to the surface of the steel pipe 3. Metal tin bars and other materials can be pushed into the groove inside the sleeve block 21 so that the cylinder 8 can vertically sink the welding torch 9 to fix the splice.
