Description

Technical Field

[0001] This application relates to the field of metal pipe processing technology, and in particular to an auxiliary device for welding the end of a round pipe. Background Technology

[0002] Currently, metal round pipes are widely used in the metal pipe manufacturing industry, covering numerous fields such as construction, machinery manufacturing, and petrochemicals. With the continuous development of industry, higher demands are being placed on the quality and production efficiency of metal round pipes. Among these, the welding of the ends of the metal round pipes to components such as sleeves or flanges, as well as the material cutting process, are crucial, directly affecting the overall performance and safety of the round pipe in use.

[0003] In existing technologies, the welding and unloading of metal round tubes to components such as sleeves or flanges is commonly done manually. In this manual operation mode, workers rely on their skills and experience to position and weld the round tubes, and then manually transport the welded tubes to the unloading area for unloading. This method depends on the worker's skill level and can meet production needs to a certain extent. However, for complex welding tasks, such as those requiring precise alignment and positioning, manual operation is prone to errors. Furthermore, the manual unloading method after welding consumes a significant amount of manpower, which greatly reduces production efficiency.

[0004] The aforementioned manual methods are insufficient to guarantee welding precision and stability, easily leading to inconsistent weld quality. Furthermore, manual material handling consumes significant manpower, resulting in overall low efficiency. Therefore, to address the inefficiency of welding and material handling at the ends of round pipes under traditional manual operation, this application proposes an auxiliary device for welding the ends of round pipes. Utility Model Content

[0005] To address the problem of low efficiency in welding and unloading round pipe ends under traditional manual operation, this application provides an auxiliary device for welding round pipe ends.

[0006] This application provides an auxiliary device for welding the end of a circular tube, which adopts the following technical solution: A welding auxiliary device for the end of a round pipe includes a sliding rail, on which a mounting base and a receiving and unloading mechanism for receiving and unloading the round pipe are slidably disposed. Two mounting bases are provided and located on both sides of the receiving and unloading mechanism. A three-jaw chuck is provided on the side of each mounting base near the receiving and unloading mechanism, and a drive motor is provided inside each mounting base. The side of each three-jaw chuck near the mounting base is coaxially and fixedly connected to the output shaft of the drive motor, and an adjustable clamping mechanism for fixing a sleeve or flange is provided on the side of each three-jaw chuck away from the mounting base.

[0007] By adopting the above technical solution, the sliding track allows the mounting base and the receiving and unloading mechanism to move and adjust their positions flexibly. At the same time, the receiving and unloading mechanism can receive and unload the round tube, reducing manual handling and improving unloading efficiency. The two mounting bases are located on both sides of the receiving and unloading mechanism, which facilitates simultaneous operation on both ends of the round tube. The drive motor drives the three-jaw chuck to rotate, thereby causing the round tube to rotate for circumferential welding. The adjustable clamping mechanism can flexibly adjust the clamping mode and tightness during the welding process to achieve more precise positioning and fixation, thereby improving the accuracy and efficiency of welding.

[0008] Preferably, any of the adjustable clamping mechanisms includes an adjusting track, a bidirectional lead screw, and clamping blocks. The adjusting track is detachably connected to a three-jaw chuck. One end of the bidirectional lead screw is rotatably connected to the adjusting track, and the other end passes through the adjusting track and is fixedly connected to an adjusting wheel. Two clamping blocks are provided, and the two clamping blocks are respectively threaded to both sides of the bidirectional lead screw along the axial direction. Limiting blocks that are fixedly connected to the adjusting track are provided on both sides of the bidirectional lead screw. Limiting grooves that form an embedded sliding fit with the limiting blocks are opened on both sides of each clamping block, and a flange insertion pin is provided on the side of each clamping block away from the mounting base.

[0009] By adopting the above technical solution, the adjustable track in the adjustable clamping mechanism is detachably connected to the three-jaw chuck, which facilitates the maintenance or replacement of the adjustable clamping mechanism. Turning the adjusting wheel drives the bidirectional lead screw to rotate, so that the two clamping blocks threaded on the bidirectional lead screw move along the axial direction of the bidirectional lead screw under the action of the limiting block and the limiting groove. This allows for flexible adjustment of the clamping tightness to adapt to different specifications of sleeves, increasing the versatility of the tooling. At the same time, the flange insertion pin facilitates the positioning of the flange, enabling precise operation when welding the end of the round pipe to flanges of different specifications.

[0010] Preferably, a plug-in support block is provided between the two clamping blocks, one side of the plug-in support block is fixedly connected to the limiting block and the other side is plugged into the round tube.

[0011] By adopting the above technical solution, a plug-in support block is set between the two clamping blocks. This block is fixedly connected to the limiting block and can form a plug-in fit with the round tube. This can support the round tube, enhance its stability during the welding process, and improve the welding quality.

[0012] Preferably, the receiving and unloading mechanism includes a receiving component for receiving pipe fittings and a lifting component and a transfer component disposed on the receiving component for unloading. There are two receiving components, and there are two lifting components and two transfer components corresponding to the receiving component.

[0013] By adopting the above technical solution, the receiving and unloading mechanism is equipped with two receiving components, which can be flexibly moved to support and position round pipes of different lengths. After the operator completes the welding operation, the lifting component in the receiving and unloading mechanism can lift the welded round pipe to a height higher than the receiving component, and in conjunction with the transfer component, transfer the welded round pipe to the next processing platform. This avoids the problem of a large amount of manpower being consumed by manual unloading and improves unloading efficiency.

[0014] Preferably, any of the receiving components includes a base that is slidably disposed on a sliding track and a receiving frame that is fixedly connected to the side of the base away from the adjacent mounting base, and the receiving frame has a groove that forms an embedded fit with the round tube.

[0015] By adopting the above technical solution, the base of the receiving component is slidably set on the sliding track to facilitate the flexible movement of the receiving component, so that the round tube can reach the appropriate welding position. The receiving frame and its groove on the base form an embedded fit with the round tube, which can realize the receiving and initial positioning of the round tube, and facilitate subsequent welding operations.

[0016] Preferably, any of the lifting components includes a drive cylinder, a support plate, and a lifting plate with an inclined surface. The drive cylinder is fixed inside the base, and the output shaft of the drive cylinder passes through the base and is fixedly connected to the support plate. The lifting plate is fixedly connected to the support plate and the inclined surface is kept vertically upward. Slide cylinders fixedly connected to the base are provided on both sides of the output shaft of the drive cylinder, and a slide rod with one end fixedly connected to the support plate is slidably disposed inside any of the slide cylinders.

[0017] By adopting the above technical solution, the drive cylinder in the lifting assembly drives the support plate to rise and fall, thereby driving the lifting plate to rise and fall. Since the lifting plate has an inclined surface, when both lifting plates are raised to a height higher than the receiving frame, the welded round tube can fall onto the lifting plate and roll on the inclined surface, thereby realizing the transition of the welded round tube to the transfer assembly.

[0018] Preferably, any of the aforementioned transfer components includes a fixed shaft and a rotating cylinder sleeved on one end of the fixed shaft. The end of the fixed shaft away from the rotating cylinder is fixedly connected to the machine base, and a transfer receiving rod is fixedly connected to the rotating cylinder.

[0019] By adopting the above technical solution, the combination of the fixed shaft and the rotating cylinder in the transfer assembly allows the transfer receiving rod to rotate flexibly around the fixed shaft. When the lifting assembly transfers the welded round tube to the transfer assembly, the two transfer receiving rods only need to be rotated to a direction perpendicular to the sliding track. The welded round tube can then roll on the transfer receiving rods and be transferred to the next processing platform. At the same time, when the entire equipment stops processing, the two transfer receiving rods can be rotated to a direction parallel to the sliding track for storage, thereby saving space in the processing area.

[0020] Preferably, a mounting rod is detachably connected to the side of any of the mounting bases near the receiving and unloading mechanism, and a laser marking head is fixedly connected to the end of the mounting rod away from the mounting base.

[0021] By adopting the above technical solution, a mounting rod can be detachably connected to the side of the mounting base near the receiving and unloading mechanism, and a laser marking head is fixedly connected to the end of the mounting rod away from the mounting base. This facilitates positioning and alignment using laser marking during welding, which helps improve the accuracy and stability of welding and reduce welding errors. At the same time, the detachable connection of the mounting rod makes it easy to adjust or replace according to actual needs.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By combining the mounting base on the sliding track with the three-jaw chuck and adjustable clamping mechanism, the automatic positioning and clamping of round pipes with sleeves or flanges is achieved. The adjustable clamping mechanism consists of an adjusting track, a two-way screw, and a clamping block that work together. The rotation of the two-way screw drives the clamping block to move, allowing for flexible adjustment of the clamping tightness to accommodate different specifications of sleeves. At the same time, flange insertion pins are set on the clamping block to facilitate flange positioning. This enables the equipment to operate accurately when welding the ends of round pipes with flanges of different specifications, effectively improving the accuracy and stability of welding, solving the problem of inconsistent welding quality caused by manual operation, and significantly improving welding efficiency. 2. The receiving component in the material receiving mechanism can move flexibly to support and position round tubes of different lengths. The lifting component and the transfer component can automatically lift and transfer the welded round tubes. The drive cylinder in the lifting component pushes the support plate, causing the inclined lifting plate to rise, thus lifting the round tube and transferring it to the transfer component. The rotating cylinder of the transfer component rotates around a fixed axis, driving the transfer receiving rod to rotate. The welded round tube can be transferred to the next processing platform or folded for storage to save space in the processing area, reduce manpower input, and improve the efficiency of the entire production process. The combination of the mounting rod and the laser marking head further improves the welding accuracy. Attached Figure Description

Two mounting bases 2 are provided, located on opposite sides of the receiving and unloading mechanism 3. A three-jaw chuck 4 is provided on the side of each mounting base 2 closest to the receiving and unloading mechanism 3. A drive motor 21 is fixedly installed inside each mounting base 2. In this embodiment, a drive rod 211 is coaxially fixedly connected to the output shaft of each drive motor 21, and each drive rod 211 is located away from the drive motor. One end of the motor 21 passes through the mounting base 2. The side of any three-jaw chuck 4 closest to the mounting base 2 is coaxially and fixedly connected to the corresponding drive rod 211. The side of any three-jaw chuck 4 away from the mounting base 2 is provided with an adjustable clamping mechanism 5 for fixing the sleeve or flange. The receiving and unloading mechanism 3 includes a receiving component 31 for receiving pipe fittings and a lifting component 32 and a transfer component 33 provided on the receiving component 31 for unloading. There are two receiving components 31, and there are two lifting components 32 and two transfer components 33 corresponding to the receiving component 31.

[0028] In practical use, the mounting base 2 and the receiving and unloading mechanism 3 can be flexibly adjusted on the sliding track 1. The two mounting bases 2 are located on both sides of the receiving and unloading mechanism 3, which facilitates simultaneous operation on both ends of the pipe. The drive motor 21 drives the drive rod 211 to rotate the three-jaw chuck 4, thereby driving the adjustable clamping mechanism 5 and the round pipe to rotate to achieve circumferential welding. The adjustable clamping mechanism 5 can flexibly adjust the clamping mode and tightness during the welding process to achieve more precise positioning and fixing, thereby improving the accuracy and efficiency of welding. The two receiving components 31 in the receiving and unloading mechanism 3 can move flexibly to support and position round pipes of different lengths. At the same time, the lifting component 32 and the transfer component 33 can be combined to lift the welded round pipe and transfer it to the next processing platform, avoiding the problem of a lot of manpower wasted by manual unloading and improving unloading efficiency.

[0029] Reference Figure 2 and Figure 3 In this embodiment, the sliding track 1 includes two parallel slide rails 11 with grooves 111. Four first pulleys 12 are rotatably connected to the bottom of any mounting base 2 via a pivot. The four first pulleys 12 are arranged in a rectangular array at the bottom of the mounting base 2, and each first pulley 12 forms an embedded sliding fit with the groove 111 on the slide rail 11. Any adjustable clamping mechanism 5 includes an adjusting track 51, a bidirectional lead screw 52, ​​and a clamping block 53. In this embodiment, the adjusting track 51 is U-shaped. A connecting shaft 511 is fixedly connected to the side of the adjusting track 51 closest to the three-jaw chuck 4 by welding. The bidirectional lead screw 52 is detachably and fixedly connected to the three-jaw chuck 4. One end of the bidirectional lead screw 52 is rotatably connected to the adjusting rail 51, and the other end of the bidirectional lead screw 52 passes through the adjusting rail 51 and is fixedly connected to the adjusting wheel 521 by welding. There are two clamping blocks 53, which are threadedly connected to both sides of the bidirectional lead screw 52 in the axial direction. Both sides of the bidirectional lead screw 52 in the radial direction are provided with limiting blocks 54 that are fixedly connected to the adjusting rail 51 by welding. Both sides of each clamping block 53 are provided with limiting grooves 531 that form an embedded sliding fit with the limiting blocks 54. A flange plug pin 532 is fixedly connected to the side of each clamping block 53 away from the mounting base 2 by welding.

[0030] In practical use, the first pulley 12 at the bottom of the mounting base 2 and the slide groove 111 on the slide rail 11 form an embedded sliding fit, realizing the stable adjustment of the distance between the two mounting bases 2, which facilitates operation at both ends of the round tube. The connecting shaft 511 and the three-jaw chuck 4 are detachably fixedly connected for easy maintenance or replacement. Turning the adjusting wheel 521 drives the bidirectional screw 52 to rotate. Through the limiting block 54 and the limiting groove 531, an embedded sliding fit is formed, which makes the clamping block 53 move along the axial direction of the bidirectional screw 52, ​​thereby realizing flexible adjustment of clamping tightness to adapt to different specifications of sleeves. At the same time, the flange insertion pin 532 facilitates the positioning of the flange, so that the equipment can be accurately operated when welding flanges of different specifications at the end of the round tube.

[0031] Reference Figure 1 A mounting rod 23 is detachably connected to the side of the mounting base 2 closest to the receiving and unloading mechanism 3. A laser marking head 24 is fixedly connected to the end of the mounting rod 23 away from the mounting base 2 by welding. In this embodiment, a fixing seat 22 is fixedly connected to the end of the mounting rod 23 closest to the mounting base 2 by welding. The fixing seat 22 and the mounting base 2 are detachably fixedly connected by bolts. In actual use, the laser marking head 24 facilitates positioning and alignment using laser marking during welding, reducing welding errors. At the same time, the detachable connection of the mounting rod 23 makes it convenient to adjust or replace according to actual needs.

[0032] Reference Figure 3 An insertion support block 55 is provided between any two clamping blocks 53 in any of the adjustable clamping mechanisms 5. In this embodiment, the insertion support block 55 includes a fixing part 551 and an insertion part 552, which are fixedly connected by welding. The fixing part 551 is rectangular, and the end of the fixing part 551 that overlaps with any limiting block 54 is fixedly connected to it by bolts. The insertion part 552 is cylindrical, and it forms an insertion fit with the round tube. In actual use, the insertion support block 55 can support the round tube, enhance the stability of the round tube during the welding process, and thus improve the welding quality.

[0033] Reference Figure 1 and Figure 4Each of the receiving components 31 includes a base 311 slidably mounted on a sliding rail 1 and a receiving frame 312 fixedly connected to the side of the base 311 away from the adjacent mounting base 2 by bolts. The receiving frame 312 has a groove 313 that forms an embedded fit with a round tube. In this embodiment, the bottom of the base 311 is rotatably connected to four second pulleys 13 via a rotating shaft. The four second pulleys 13 are arranged in a rectangular array at the bottom of the base 311, and each second pulley 13 forms an embedded sliding fit with a groove 111 on the sliding rail 11. Each of the lifting components 32 includes a drive cylinder 321, a support plate 322, and a lifting plate 323 with an inclined surface 3231. In this embodiment, the drive cylinder 321 is located inside the base 311 on the side closer to the adjacent mounting base 2. The output shaft of the drive cylinder 321 passes through the base 311 and is fixedly connected to the support plate 322 by welding. The lifting plate 323 is fixedly connected to the support plate 322 by welding and keeps the inclined surface 3231 vertically upward. Both sides of the output shaft of the drive cylinder 321 are provided with slide cylinders 324 that are fixedly connected to the base 311 by welding. Each slide cylinder 324 has a slide rod 325 with one end slidingly engaged with the slide cylinder 324 and the other end fixedly connected to the support plate 322 by welding. Each transfer assembly 33 includes a fixed shaft 331 and a rotating cylinder 332 sleeved on one end of the fixed shaft 331. The end of the fixed shaft 331 away from the rotating cylinder 332 is fixedly connected to the base 311 by bolts. A transfer receiving rod 333 is fixedly connected to the rotating cylinder 332 by welding.

[0034] In practical use, the second pulley 13 at the bottom of the base 311 and the slide groove 111 on the slide rail 11 form an embedded sliding fit to facilitate the flexible movement of the receiving component 31, allowing the round tube to be flexibly adjusted to a suitable welding position following the receiving component 31. The receiving frame 312 has a groove 313 that forms an embedded fit with the round tube to realize the receiving and positioning of the round tube, which facilitates subsequent welding operations. After the welding of the end of the round tube is completed, the drive cylinder 321 drives the support plate 322 and the lifting plate 323 to rise and fall. Since the lifting plate 323 has an inclined surface 3231, when the two lifting plates 32 When all three components are raised to a height higher than the receiving frame 312, the welded round tube can fall onto the lifting plate 323 and roll on the inclined surface 3231, thereby transitioning the welded round tube to the transfer assembly 33. At this time, the transfer receiving rods 333 in the two transfer assemblies 33 are rotated to a direction perpendicular to the sliding track 1, and the welded round tube can roll on the transfer receiving rods 333 and be transferred to the next processing platform. At the same time, when the entire equipment stops processing, the two transfer receiving rods 333 can be rotated to a direction parallel to the sliding track 1 for storage, thereby saving space in the processing area.

[0035] The implementation principle of this application embodiment is as follows: the receiving component 31 in the mounting base 2 and the receiving and unloading mechanism 3 is flexibly adjusted on the sliding track 1 through the first pulley 12 and the second pulley 13 respectively, so as to realize the operation at both ends of the round tubes of different sizes at the same time. The drive motor 21 drives the three-jaw chuck 4 to rotate the adjustment track 51 to realize the circumferential welding of the round tube. The bidirectional screw 52 in the adjustable clamping mechanism 5 is combined with the clamping block 53 and the limiting block 54, which can flexibly adjust the clamping tightness during the welding process to adapt to the sleeves of different specifications, so as to achieve more precise positioning and fixing. At the same time, the flange insertion pin 532 facilitates the positioning of the flange, so that the equipment can also operate precisely when welding the end of the round tube with flanges of different specifications. The insertion support block 55 enhances the stability of the round tube during the welding process. The laser marking head 24 facilitates the positioning and alignment of the laser marking during welding, reduces welding errors, and improves the accuracy and efficiency of welding. The receiving frame 312 in the receiving assembly 31 has a groove 313 that fits into the round tube, realizing the receiving and positioning of the round tube for subsequent welding operations. After the end of the round tube is welded, the drive cylinder 321 in the lifting assembly 32 drives the support plate 322 and the lifting plate 323 to rise and fall. The welded round tube can then fall on the lifting plate 323 and roll on the inclined surface 3231 before being transferred to the transfer assembly 33. At this time, the transfer receiving rods 333 in the two transfer assemblies 33 are rotated to a direction perpendicular to the sliding track 1. The welded round tube can then roll on the transfer receiving rods 333 and be transferred to the next processing platform. This avoids the problem of a lot of manpower wasted by manual handling of the unloading method and improves the unloading efficiency. At the same time, when the entire equipment stops processing, both transfer receiving rods 333 can be rotated to a direction parallel to the sliding track 1 for storage, thereby saving space in the processing area.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
