Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically a pipeline welding machine with a positioning structure. Background Technology

[0002] Pipe welding is a process of connecting two or more pipes together. It is widely used in industries such as petroleum, chemical, natural gas, shipbuilding, and power. In the process of using pipelines, there are often situations where two pipelines are short and need to be connected together by welding.

[0003] Publication No. CN220278762U discloses a pipe welding machine. This device can easily position the pipes to be welded using a positioning component. Then, an adjustment mechanism can control the relative movement of the positioning seat to clamp and assemble two pipes, facilitating subsequent welding. The positioning component is rotatably connected to the clamping seat via bearings. After the two pipes are clamped and assembled, rotating one pipe will simultaneously rotate the other pipe, thus enabling circumferential welding while the welding torch is fixed. This facilitates the welding of two pipes. However, this patent still has the following problems in practical use: This device can easily position the pipes to be welded using positioning components. Then, the adjustment mechanism can control the relative movement of the positioning seats to clamp the two pipes together, facilitating subsequent welding work. However, because the device uses a dual-head motor to drive the rotation of two sets of screws to achieve relative movement of the adjustment blocks, it cannot weld pipes of different lengths, which greatly reduces the flexibility of the device and limits the operation for workers.

[0004] A pipe welding machine with a positioning structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe welding machine with a positioning structure to solve the problem mentioned in the background art. Currently, the positioning component can be used to conveniently position and place the pipe to be welded. Then, the adjustment mechanism can be used to control the relative movement of the positioning seat to clamp the two pipes together, which is convenient for subsequent welding work. However, since the device drives the rotation of two sets of screws by a double-headed motor to realize the relative movement of the adjustment block, the device cannot weld pipes of different lengths, which greatly reduces the flexibility of the device during use and brings limitations to the operators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe welding machine with a positioning structure, including a base, a support plate being provided on one side of the top end of the base; a positioning mechanism being provided at the top end of the base, and a limit component being provided inside the positioning mechanism; The positioning mechanism includes a bracket mounted on one side of the top of the base. A threaded rod is rotatably connected inside the bracket, and a forward / reverse motor is installed at one end of the threaded rod. A moving block is threadedly connected to the outer side of the threaded rod, and a connecting rod is installed at the top of the moving block. A first conical rubber block is rotatably connected to one side of the top of the connecting rod. A drive rod is rotatably connected inside the support plate, and a second conical rubber block is fixedly connected to one end of the drive rod. A limit box is installed on one side of the support plate, and a fixed tube is installed inside the top of the limit box. A moving rod is slidably connected inside the fixed tube, and a first contraction spring is sleeved on the outer side of the moving rod. A push plate is installed at the bottom of the moving rod, and slots are opened on the outer side of the drive rod. An insertion block is installed at the bottom of the push plate, and the insertion block is inserted into the slot.

[0007] Preferably, support rods are symmetrically installed between the support plate and the bracket, and a sliding plate is slidably connected between the outer sides of the support rods. A welding frame assembly is installed at the center of the top of the sliding plate, and annular plates are symmetrically installed at the top of the sliding plate. A retractable rod is installed on the inner side of each annular plate, and a second retractable spring is sleeved on the outer side of the retractable rod. A fixing block is installed at one end of the retractable rod, and a ball bearing is slidably connected to one side of the fixing block.

[0008] Preferably, the limiting component includes a sliding box installed on one side of the slide plate, and a positioning rod is installed inside the sliding box. Pull blocks are symmetrically slidably connected to the outer side of the positioning rod. A movable rod is rotatably connected to one side of the bottom end of the pull block. A third contraction spring is installed between the pull blocks. A connecting block is rotatably connected between the bottom ends of the movable rod. A positioning plate is installed at the bottom end of the connecting block. A positioning groove is opened at the top of the base. A positioning block is installed at the bottom end of the positioning plate. The positioning block is inserted into the positioning groove.

[0009] Preferably, a fixing rod is installed on the inner bottom side of the bracket, and a sliding sleeve is sleeved on the outer side of the fixing rod, and the top end of the sliding sleeve is fixedly connected to the moving block.

[0010] Preferably, a handle is installed at the end of the drive rod away from the support plate.

[0011] Preferably, the top end of the pull block passes through the sliding box and is slidably connected to the sliding box.

[0012] Preferably, the third retraction spring is located outside the positioning rod and is slidably connected to the positioning rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: A pipe welding machine with a positioning structure is described below: A forward and reverse motor drives the rotation of a threaded rod, the movement of a moving block drives the movement of a connecting rod, and the movement of the connecting rod drives the movement of a first conical rubber block. At this time, the corresponding ends of two sets of pipes are tightly fitted together. The operator rotates the drive rod, causing the first conical rubber block to rotate. Utilizing the high friction of the rubber block, the two sets of pipes rotate. The welding torch then performs circumferential welding on the pipe connection. The operator pulls the moving rod, which slides inside the fixed pipe. This causes the moving rod to move the push plate, which in turn causes the first contraction spring to contract. Through the restoring property of the first contraction spring, multiple sets of inserts can be inserted into the slots, thus achieving the effect of quickly fixing the limiting drive rod. This allows for quick adjustment and fixing of the two sets of pipes, thus meeting the needs of different lengths. The single-pipe welding system greatly improves the flexibility of the device during use, and the rotation of the drive rod can drive two sets of pipes to rotate accordingly, thereby improving the pipe welding efficiency. Furthermore, the use of limiting structures such as insert blocks to limit the drive rod effectively prevents pipe deviation and wobbling during welding, greatly improving the stability of the device during welding. By moving two sets of pull blocks back-to-back inside the sliding box, the pull blocks slide outside the positioning rod. At this time, the third contraction spring extends, and the movement of the pull blocks drives the movement of the movable rod. The rotation of the movable rod pulls the connecting block upwards, and the contraction of the third contraction spring allows the movable rod to quickly rotate and reset. Multiple sets of positioning blocks then insert into the positioning grooves, achieving a quick fixation of the limiting slide plate, effectively preventing wobbling and deviation of the slide plate during pipe welding, thus further improving the stability of the pipe welding process.

[0014] 1. The worker attaches one end of the first pipe to the outside of the second conical rubber block, and then attaches one end of the second pipe to the outside of the first conical rubber block. The worker then starts the forward and reverse motors to rotate the threaded rod. The rotation of the threaded rod moves the moving block, which in turn moves the connecting rod, which in turn moves the first conical rubber block. At this point, the corresponding ends of the two sets of pipes are tightly fitted together. The worker then operates the welding torch inside the welding frame assembly to weld the pipe connection. Next, the worker rotates the drive rod to rotate the first conical rubber block. Utilizing the high friction of the rubber block, the two sets of pipes rotate. The welding torch then welds the entire circumference of the pipe connection. The worker pulls the moving rod, which slides inside the fixed pipe. This causes the push plate to move, and the push plate's movement causes the first contraction spring to contract. By releasing the moving rod and utilizing the return property of the first contraction spring, multiple sets of inserts can be inserted into the slots, achieving the effect of quickly fixing the limit drive rod. The device allows for rapid adjustment and fixation of two sets of pipes, accommodating pipes of varying lengths and significantly improving flexibility during use. The rotation of the drive rod causes both sets of pipes to rotate, enhancing welding efficiency. Limiting structures such as insert blocks effectively prevent pipe shifting and wobbling during welding, greatly improving stability and providing convenience for operators. When welding pipes of different lengths, the operator slides the slide plate across the surfaces of the two support rods. The two annular plates are positioned on the outer sides of one end of each pipe. The welding torch inside the welding frame aligns with the pipe connection point. As the pipe moves within the annular plates, ball bearings roll on the pipe surface. A second contraction spring then automatically adjusts the contraction rod according to the pipe specifications, providing rapid support and conduction for various pipe sizes. This ensures greater stability during welding, effectively reducing pipe shifting after welding and enhancing practicality for operators. 2. By moving two sets of pull blocks back-to-back inside the sliding box, the pull blocks slide outside the positioning rod. At this time, the third contraction spring extends, and the movement of the pull blocks drives the movement of the movable rod. The rotation of the movable rod pulls the connecting block upward. Then, by releasing the pull blocks, the contraction of the third contraction spring allows the movable rod to quickly rotate and reset. The movable rod then pushes the connecting block and the positioning plate downward. At this time, multiple sets of positioning blocks are inserted into the positioning groove, thereby achieving the effect of quickly fixing the limiting slide plate. This effectively prevents the slide plate from shaking or shifting when the welding torch is welding the pipe, thus further improving the stability of pipe welding and bringing convenience to the operator.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides a technical solution: a pipe welding machine with a positioning structure, including a base 1, a support plate 101 is provided on one side of the top of the base 1; a positioning mechanism 2 is provided on the top of the base 1, and a limit component 3 is provided inside the positioning mechanism 2. The positioning mechanism 2 includes a bracket 201 mounted on one side of the top of the base 1. A threaded rod 202 is rotatably connected inside the bracket 201, and a forward / reverse motor 203 is mounted at one end of the threaded rod 202. A moving block 204 is threadedly connected to the outer side of the threaded rod 202, and a connecting rod 205 is mounted at the top of the moving block 204. A first conical rubber block 206 is rotatably connected to one side of the top of the connecting rod 205. A drive rod 207 is rotatably connected inside the support plate 101, and a second conical rubber block 208 is fixedly connected to one end of the drive rod 207. A limit box 209 is mounted on one side of the support plate 101, and a fixing tube 210 is installed inside the top of the limit box 209. A moving rod 211 is slidably connected inside the fixing tube 210. A first retraction spring 212 is sleeved on the outer side of the moving rod 211, and a push plate 213 is installed at the bottom end of the moving rod 211. Slots 214 are opened on the outer side of the driving rod 207, and insert blocks 215 are installed at the bottom end of the push plate 213. The insert blocks 215 are inserted into the slots 214, thereby achieving the effect of quickly adjusting and fixing the two sets of pipes. This can meet the welding of pipes of different lengths, greatly improving the flexibility of the device during use. The rotation of the driving rod 207 can drive the two sets of pipes to rotate, thereby improving the pipe welding efficiency. The limiting structure such as the insert blocks 215 limits the driving rod 207, thereby effectively preventing the phenomenon of deviation and shaking during pipe welding, greatly improving the stability of the device during welding, and bringing convenience to the staff during use. Support rods 216 are symmetrically installed between the support plate 101 and the bracket 201. A sliding plate 217 is slidably connected between the outer sides of the support rods 216. A welding frame assembly 218 is installed at the center of the top of the sliding plate 217. Annular plates 219 are symmetrically installed at the top of the sliding plate 217. A contraction rod 220 is installed on the inner side of each annular plate 219. A second contraction spring 221 is sleeved on the outer side of each contraction rod 220. A fixing block 222 is installed at one end of each contraction rod 220, and a ball bearing 223 is rolled inside one side of the fixing block 222. When the pipe moves inside the annular plate 219, the ball bearing 223 rolls on the pipe surface. At this time, the second contraction spring 221 drives the contraction rod 220 to automatically adjust its contraction or extension according to the pipe specifications, thereby enabling rapid support of pipes of various specifications. The support and conduction effect makes the pipe welding process more stable and effectively reduces the phenomenon of displacement after the two sets of pipes are welded, which brings practicality to the staff. A fixed rod 224 is installed on the inner bottom side of the bracket 201, and a sliding sleeve 225 is sleeved on the outer side of the fixed rod 224. The top of the sliding sleeve 225 is fixedly connected to the moving block 204. The movement of the moving block 204 drives the movement of the sliding sleeve 225. At this time, the sliding sleeve 225 slides on the outer side of the fixed rod 224, thereby achieving the effect of guiding the movement of the moving block 204, which greatly improves the stability of the first conical rubber block 206 when it moves. A handle 226 is installed on the end of the drive rod 207 away from the support plate 101. The design of the handle 226 makes it easy for the staff to operate the drive rod 207.

[0019] The limiting component 3 includes a sliding box 301 installed on one side of the slide plate 217, and a positioning rod 302 is installed inside the sliding box 301. A pull block 303 is symmetrically slidably connected to the outer side of the positioning rod 302. The top end of the pull block 303 passes through the sliding box 301 and is slidably connected to it. A movable rod 304 is rotatably connected to one side of the bottom end of the pull block 303. A third contraction spring 305 is installed between the pull blocks 303. The third contraction spring 305 is located outside the positioning rod 302 and is slidably connected to it. The movable rod 304... A connecting block 306 is rotatably connected between the bottom ends of 04, and a positioning plate 307 is installed at the bottom end of the connecting block 306. A positioning groove 308 is opened at the top end of the base 1, and a positioning block 309 is installed at the bottom end of the positioning plate 307. The positioning block 309 is inserted into the positioning groove 308, thereby achieving the effect of quickly fixing the limiting slide plate 217. This effectively prevents the slide plate 217 from shaking or shifting when the welding torch is welding the pipe, thereby further improving the stability of the pipe welding and bringing convenience to the workers during use.

[0020] Working principle: Before using this type of pipe welding machine with a positioning structure, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the worker attaches one end of the first pipe to the outside of the second conical rubber block 208, and then attaches one end of the second pipe to the outside of the first conical rubber block 206. The worker then starts the forward / reverse motor 203, which drives the threaded rod 202 to rotate. The rotation of the threaded rod 202 causes the moving block 204 to move, which in turn moves the connecting rod 205. The movement of the connecting rod 205 then moves the first conical rubber block 206. At this point, the first and second pipes move in a convergent-unfolding trajectory, with their corresponding ends tightly fitted together. The worker then operates the welding torch inside the welding frame assembly 218 to weld the pipe connection. Finally, the worker rotates the drive rod 207 to move the first conical... The rotation of rubber block 206 causes the first conical rubber block 206 and the second conical rubber block 208 to deform under pressure. Utilizing the high friction of the rubber blocks, the two sets of pipes rotate. At this time, the welding torch performs circumferential welding on the pipe connections. The worker pulls the moving rod 211, which slides inside the fixed pipe 210. The moving rod 211 moves the push plate 213, causing the first contraction spring 212 to contract. Releasing the moving rod 211 and allowing the first contraction spring 212 to return to its original position allows multiple sets of inserts 215 to connect with the slots 214, thus achieving the effect of quickly fixing the limit drive rod 207. This enables rapid adjustment and fixing of the two sets of pipes. The ability to weld pipes of varying lengths greatly enhances the flexibility of the device during use. The rotation of the drive rod 207 causes two sets of pipes to rotate, improving welding efficiency. Furthermore, the use of limiting structures such as the insert block 215 to limit the drive rod 207 effectively prevents pipe misalignment and wobbling during welding, significantly improving the device's stability and providing convenience for operators. When welding pipes of varying lengths, the operator slides the slide plate 217 across the surfaces of the two support rods 216. At this time, the two annular plates 219 are positioned on the outer sides of one end of each pipe. The welding torch inside the welding frame assembly 218 corresponds to the pipe connection point. As the pipe moves within the annular plate 219, the ball bearings 2... 23 rolls on the pipe surface. At this time, the second contraction spring 221 drives the contraction rod 220 to automatically adjust the contraction or extension according to the pipe specifications, thereby achieving the effect of quickly supporting and transmitting pipes of various specifications. This makes the pipe welding process more stable and effectively reduces the phenomenon of displacement after the two sets of pipes are welded, bringing practicality to the workers. The movement of the moving block 204 drives the movement of the sliding sleeve 225. At this time, the sliding sleeve 225 slides outside the fixed rod 224, thereby achieving the effect of guiding the movement of the moving block 204, greatly improving the stability of the first conical rubber block 206 when it moves. The design of the handle 226 makes it easy for the workers to operate the drive rod 207. By moving two sets of pull blocks 303 back-to-back inside the sliding box 301, the pull blocks 303 slide outside the positioning rod 302. At this time, the third contraction spring 305 extends, and the movement of the pull blocks 303 drives the movement of the movable rod 304. The rotation of the movable rod 304 pulls the connecting block 306 upward. Then, by releasing the pull blocks 303, the contraction of the third contraction spring 305 allows the movable rod 304 to quickly rotate and reset. The movable rod 304 then pushes the connecting block 306 and the positioning plate 307 downward. At this time, multiple sets of positioning blocks 309 are inserted into the positioning groove 308, thereby achieving the effect of quickly fixing the limiting slide plate 217. This effectively prevents the slide plate 217 from shaking or shifting when the welding torch is welding the pipe, thus further improving the stability of pipe welding and providing convenience for the operator.
