Description

Technical Field

[0001] This invention relates to the field of welding preparation, specifically to a welding system. Background Technology

[0002] Automated welding equipment is a key piece of equipment in modern manufacturing to improve welding efficiency and ensure quality stability. In actual production, there are many types of workpieces to be welded, and the required weld types are also different: for example, some workpieces have circumferential welds that need to be welded, while others have welds that need to be welded along the axial direction. In addition, there are other types such as transverse welds that require the workpiece and welding torch to be adjusted to a specific spatial posture before welding can be performed.

[0003] Currently, many welding equipment are designed with relatively singular functions, typically specialized for a specific type of workpiece or weld pattern. This limitation of functional specialization means that manufacturers often need to configure multiple dedicated production lines or frequently change and adjust tooling fixtures to meet the different welding requirements of various workpieces. This approach not only leads to low equipment utilization and poor production line flexibility, but also severely impacts overall processing efficiency due to frequent tooling changes and production line switching. Summary of the Invention

[0004] The purpose of this invention is to address the above problems by providing a welding system that can adapt to various welding requirements, thereby improving equipment utilization and processing efficiency, and enhancing production line flexibility.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is a welding system, which includes a processing unit, comprising a longitudinal clamping unit, a welding processing unit, and a transverse clamping unit arranged sequentially. The welding processing unit includes a sliding table and a transport platform mounted on the sliding table. The transport platform has at least two degrees of freedom of movement. The sliding table can move along a horizontally arranged slide rail, the length direction of which is perpendicular to the arrangement direction of the longitudinal clamping unit, the welding processing unit, and the transverse clamping unit. A welding execution unit is provided on the transport platform. The longitudinal clamping unit includes a rotatably arranged bearing platform, the rotation axis of which is parallel to the length direction of the slide rail. A workpiece mounting platform is provided on the bearing platform. The transverse clamping unit includes a support unit and a rotating disk, the rotation axis of which is parallel to the length direction of the slide rail. A clamping device is provided on the side of the rotating disk facing the support unit. The support unit includes a lifting unit and a lifting mechanism. Two lifting units are located on both sides of the rotation axis of the rotating disk, and the lifting units can move vertically under the drive of the lifting mechanism.

[0006] The sliding table can move laterally along a preset guide rail, thereby expanding the horizontal working range of the welding execution unit. The transport platform, based on the sliding table, can drive the welding execution unit to move and rotate in multiple directions, achieving movements such as lifting, tilting, and swaying. This allows for flexible and precise adjustment of the welding execution unit's posture. The welding execution unit includes existing welding equipment such as welding torches. The workpiece is clamped on the carrier platform's platform, allowing the platform to rotate the workpiece to flexibly adjust the welding area, thereby reducing or eliminating welding dead angles.

[0007] The lateral clamping unit grips one end of the workpiece and rotates it around the lateral axis. The support unit lifts the lower surface of the workpiece away from the clamping unit, providing stable support for the overhanging portion of the workpiece to resist bending deformation and tilting caused by its own weight. This effectively suppresses vibration during rotation, providing structural support for operations such as circumferential welding and lateral welding, thereby improving processing accuracy and stability. A lifting mechanism drives the lifting unit to move vertically, adjusting its support height over the workpiece. Ultimately, this achieves the effect of adapting to various welding requirements, improving equipment utilization and processing efficiency, and enhancing the flexibility of the production line.

[0008] Furthermore, to expand the degrees of freedom and enable the welding of circumferential welds, the stage is rotatably mounted on the support platform, with the axis of rotation of the stage perpendicular to the axis of rotation of the support platform. When welding circumferential welds (such as circumferential welds on circular pipes), the workpiece can be mounted on the stage, and the circumferential weld can be welded by rotating the stage at a uniform speed. To quickly clamp workpieces and accommodate different workpieces, the stage is detachably equipped with tooling fixtures such as chucks.

[0009] Furthermore, the supporting platform includes a transverse platform for mounting the workpiece stage. The length direction of the transverse platform is parallel to the length direction of the slide rail. The end of the transverse platform is fixedly connected to a rotating arm. The rotating arm is rotatably mounted on the machine base via a rotating shaft. When the rotating arm is in a vertical state, the axis of the rotating shaft and the transverse platform are not on the same horizontal plane. This causes the rotation axis of the supporting platform to deviate from the workpiece placement surface. When the workpiece rotates from vertical to longitudinal, the transverse platform in the supporting platform will move away from the welding processing section, causing the transverse platform to be misaligned with the sliding table. This prevents interference between the rotation of the supporting platform and the lateral movement of the transport platform, as well as the posture adjustment of the welding execution unit, thereby improving the safety and reliability of equipment operation and assisting the welding execution unit in its work.

[0010] Furthermore, the lifting mechanism is a scissor arm, with the lower ends of the scissor arms hinged to two transverse platforms. The two transverse platforms are symmetrically arranged on both sides of the rotation axis of the rotary disk. The two transverse platforms are threadedly engaged with two sections of threads with opposite directions on the bidirectional screw. By rotating the bidirectional screw, the two transverse platforms move towards or away from each other, thereby realizing the unfolding and retraction of the scissor arms. In this way, only one drive source is needed to drive the bidirectional screw to complete the entire lifting action. At the same time, the self-locking characteristic of the screw drive is utilized to reliably lock the workpiece in the required position when there is no power input, thereby improving safety.

[0011] Furthermore, at least two support portions are provided, which are spaced apart along the length of the slide rail. By having multiple support portions spaced apart along the axial direction of the workpiece, a more stable support is provided for the workpiece.

[0012] Furthermore, to accommodate workpieces of different lengths and expand the processing range, at least one support located on the far side of the rotary table is slidably mounted on the base, with its sliding direction parallel to the length direction of the slide rail.

[0013] Furthermore, to improve automation and production efficiency, a transfer unit is also included. This transfer unit comprises a support and a conveying unit. The conveying unit is located on one side of the processing unit, and the support is positioned above the processing unit and can move along the arrangement directions of the longitudinal clamping unit, the welding processing unit, and the transverse clamping unit. A lifting drive mechanism is mounted on the support, and its output end is fixedly connected to the bracket. A load beam is rotatably mounted on the bracket, with its axis parallel to the length direction of the slide rail in a horizontal state. The conveying unit is used to transfer the workpiece to be processed to the loading / unloading area of ​​the load beam. Through the coordinated action of the support, the lifting drive mechanism, and the load beam, the workpiece located in the loading / unloading area can be moved and precisely placed in the clamping area of ​​the longitudinal or transverse clamping unit.

[0014] Furthermore, at least three adjustment parts are circumferentially distributed around the axis of the load-bearing beam, and each adjustment part can move synchronously along the radial direction of the load-bearing beam. The at least three circumferentially distributed adjustment parts together constitute a centering mechanism. When the workpiece is placed on the load-bearing beam, by driving all the adjustment parts to move synchronously, the position of the workpiece can be contacted and corrected from multiple directions at the same time, so that its axis automatically coincides with the axis of the load-bearing beam, ensuring the accuracy of the loading process.

[0015] Furthermore, the end of the load-bearing beam is provided with a baffle that can move radially therein, and a pusher plate is also provided on the load-bearing beam, which can reciprocate along the axial direction of the load-bearing beam. When the workpiece is placed on the load-bearing beam, the baffle moves radially outward along the load-bearing beam to form a limit on the axial movement path of the workpiece; then the pusher plate moves along the axis of the load-bearing beam toward the baffle side, pushing the workpiece so that one end abuts against the baffle and the other end abuts against the pusher plate, thereby achieving precise positioning of the workpiece in the axial direction of the load-bearing beam. When the workpiece moves to the clamping position or is processed, the baffle moves radially inward along the load-bearing beam, exiting the axial movement path of the workpiece; then the pusher plate moves along the axis of the load-bearing beam away from the baffle, pushing the workpiece toward the end of the load-bearing beam to facilitate workpiece clamping and unloading.

[0016] Furthermore, the baffle is a telescopic structure whose length can be adjusted radially along the load-bearing beam. This telescopic structure allows the effective length of the baffle to be flexibly adjusted according to the specific diameter of the workpiece. For large-diameter workpieces, the baffle can be extended to ensure effective limiting contact; for small-diameter workpieces, the baffle can be shortened to avoid interference and reduce unnecessary structural space, achieving flexible compatibility with a wider range of workpiece sizes.

[0017] The beneficial effects of this invention are as follows: By setting the welding execution unit on a sliding table that can move laterally along a slide rail and a multi-degree-of-freedom transport platform, this invention allows the welding torch to not only cover a large horizontal working area but also flexibly and precisely adjust its spatial posture (such as lifting, pitching, and yaw). This design greatly enhances the welding torch's ability to follow complex weld seam trajectories, effectively adapting to weld seams with various spatial orientations on different workpieces and significantly reducing welding dead angles.

[0018] The longitudinal and transverse clamping sections can meet the clamping requirements of various weld types, adapt to various welding requirements, improve equipment utilization and processing efficiency, and enhance the flexibility of the production line. Attached Figure Description

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0032] Example 1: As Figures 1-10 As shown, this embodiment discloses a welding system, which includes a processing unit, comprising a longitudinal clamping unit 1, a welding processing unit 2, and a transverse clamping unit 3 arranged in sequence.

[0033] The welding processing unit 2 includes a sliding table 201, a transport platform 202, a slide rail 203, and a welding execution unit 204. The slide rail 203 is fixedly installed on the ground or other mounting base. In this embodiment, the length direction of the slide rail 203 is defined as the transverse direction, the width direction of the slide rail 203 (i.e., the arrangement direction of the longitudinal clamping part 1, the welding processing unit 2, and the transverse clamping part 3) is defined as the longitudinal direction, and the height direction of the slide rail 203 is defined as the vertical direction. The sliding table 201 and the slide rail 203 form a sliding pair. The sliding table 201 can move laterally along the slide rail 203 under the action of linear drive mechanisms such as lead screws and linear modules driven by servo motors. In this embodiment, the transport platform 202 is an industrial robot manipulator with five to six degrees of freedom of motion. The base of the transport platform 202 is fixed on the sliding table 201. Through the combined motion of multiple joints, the welding execution unit 204 on the transport platform 202 has the ability to adjust various postures. The welding execution unit 204 is installed on the end interface of the transport platform 202 and is used to perform welding. The welding execution unit 204 includes a welding torch, etc.

[0034] The longitudinal clamping part 1 includes a support platform 101, a loading stage 102, and a base 106. The support platform 101 includes a transverse stage 104 and a rotating arm 105. The base 106 is fixed to the ground or other platform. The rotating arm 105 is rotatably mounted on the base 106 via a rotating shaft. The rotating shaft on the rotating arm 105 is driven by a servo motor and a reducer installed in the base 106. When the rotating arm 105 is in a vertical state, the rotating shaft is located at the upper part of the rotating arm 105. In this state, the end of the transverse stage 104 is fixedly connected to the lower part of the rotating arm 105, so that the axis of the rotating shaft and the transverse stage 104 are not on the same horizontal plane. The length direction of the transverse platform 104 is parallel to the length direction of the slide rail 203. The loading platform 102 is rotatably mounted on the transverse platform 104. Therefore, when the rotating arm 105 is in a vertical state, a rotating shaft is fixedly provided on the lower surface of the loading platform 102. A motor is provided inside the transverse platform 104. The output shaft of the motor is connected to the rotating shaft through a coupling, gear, etc. The rotation axis of the loading platform 102 is perpendicular to the rotation axis of the bearing platform 101. The rotation axis of the bearing platform 101 is parallel to the length direction of the slide rail 203. The loading platform 101 is provided with a loading platform 102 for fixing the workpiece 4.

[0035] The stage 102 is detachably equipped with a first chuck 107. For this purpose, the stage 102 can be provided with threaded holes, etc. The first chuck 107 can be customized according to the shape of different workpieces to achieve quick replacement, or an existing three-jaw chuck can be used.

[0036] The transverse clamping part 3 includes a support part, a rotating disk 301, and a base 307. The support part includes a lifting part 303 and a lifting mechanism 304. The lifting part 303 can move vertically under the drive of the lifting mechanism 304 to adjust the support height for the workpiece. The lifting mechanism 304 can be an existing linear drive device such as a hydraulic cylinder. In this embodiment, the lifting mechanism 304 is a scissor arm, which is formed by two arms hinged together by a pin. The pin is located in the middle of the arms. From a top view, the axis of the pin coincides with the rotation axis of the rotating disk 301. The lower ends of the two arms are respectively hinged to two transverse platforms 305. The lifting part 303 is rotatably mounted on the upper end of the arms. The lifting parts 303 are distributed on both sides of the axis of the rotating disk 301. In this embodiment, the lifting part 303 is a roller, and the axis of the roller is parallel to the rotation axis of the rotating disk 301.

[0037] The base 307 and the slide rail 203 are arranged in the same direction, and the upper surface of the base 307 is... Figure 9 A column 309 is provided on the right side, and a rotary drive mechanism such as a motor is installed inside the column 309. The output shaft of the rotary drive mechanism extends out of the column 309 and is connected to the rotary disk 301 for transmission. The rotation axis of the rotary disk 301 is parallel to the length direction of the slide rail 203. On the disk surface of the rotary disk 301 facing the support, a second chuck, which serves as a clamping device 302, is fixedly installed by bolts or the like. The second chuck can be a three-jaw chuck. The axis of the second chuck is coaxial with the rotation axis of the rotary disk 301, thereby ensuring that the second chuck can rotate coaxially with the rotary disk 301.

[0038] The upper surface of the base 307 is Figure 9 Multiple bases 308 are spaced apart on the left side of the base 307. The bases 308 are spaced apart along the length of the base 307. In this embodiment, two bases 308 are used for illustration. A support is installed on each base 308. The base 308 slides along the length of the base 307 under the drive of a linear module, a motor-driven lead screw, etc., so that the support can be adjusted in position along the length of the slide rail 203.

[0039] The base 308 is provided with a track extending along the width direction of the slide rail 203. Two transverse platforms 305 are slidably arranged on the track, and the two transverse platforms 305 are symmetrically arranged on both sides of the axis of the rotating disk 301. The two transverse platforms 305 are respectively threadedly connected to two threaded sections of the bidirectional screw 306 with opposite directions of rotation and symmetrical about the axis of the rotating disk 301. The bidirectional screw 306 is connected to the output shaft of the geared motor installed on the base 308. The geared motor drives the bidirectional screw 306 to rotate, which drives the two transverse platforms 305 to move towards or away from each other, thereby driving the scissor arms to unfold or retract.

[0040] Specific working process: When welding transverse workpieces, the position of the base 308 is moved according to the length of workpiece 4 to adjust the distance between the two supports to meet the support requirements of workpiece 4. Then, the bidirectional screw 306 is driven to rotate, causing the transverse table 305 to move in opposite directions under the drive of the screw. The movement of the transverse table 305 causes the scissor arms hinged to it to retract or extend, thereby driving the two rollers set on the upper end of the scissor arms to rise and fall. This allows the cantilevered part of the pipe to be supported on the rollers of the support. By visual inspection or a level, the axis of workpiece 4 is made to be coaxial with the rotation axis of the rotary disk 301. After the height adjustment is completed, one end of workpiece 4 is placed into the clamping device 302 and clamped. The processing operation can then begin. During welding, the sliding table 201 carries the welding execution unit 204 and moves along the slide rail 203 to perform transverse welding. If a circumferential weld is required, the welding execution unit 204 moves to the starting point and maintains a fixed position. The rotating disk 301 drives the clamped workpiece 4 to rotate at a uniform speed. At this time, the overhanging part of the pipe is supported by rollers.

[0041] When welding a longitudinal workpiece, the workpiece to be welded is clamped on the first chuck 107, with the axis of workpiece 4 perpendicular to the length direction of the slide rail 203. During welding, the welding execution unit 204 is adjusted to the vicinity of the welding area by the lateral movement of the sliding table 201. Subsequently, the coordinated movement of the joints of the transport platform 202, the rotation of the bearing platform 101, and the rotation of the stage 102 achieves the coordinated movement between the welding execution unit 204 and the weld, thereby ensuring that the welding torch is always aligned with the weld at the optimal angle and position, effectively eliminating welding dead angles. When welding a circumferential weld is required, the welding execution unit 204 moves to the starting point and maintains a fixed position. At this time, the stage 102 is driven to rotate at a uniform speed to complete the welding of the entire circumferential weld.

[0042] Example 2, as Figure 2 , Figure 3 , Figure 11 As shown, the other structures and working processes of this embodiment are the same as those of Embodiment 1. However, this embodiment also includes a transfer unit, which includes a support 501 and a conveying unit 502. The conveying unit 502 is located on one side of the processing unit and can be a roller conveyor or the like. It is used to intermittently transfer the workpiece 4 to be processed to the designated loading and unloading area. In this embodiment, the loading and unloading area is located on the extended line of the longitudinal clamping unit 1, the welding processing unit 2 and the transverse clamping unit 3.

[0043] The support 501 is positioned above the processing section and can move along the arrangement direction of the longitudinal clamping section 1, the welding processing section 2, and the transverse clamping section 3. A mounting frame is provided above the processing section, and a longitudinal guide rail is mounted on the mounting frame. The support 501 is positioned on the longitudinal guide rail and is driven by a precision lead screw and nut mechanism or linear module driven by a servo motor. An electric cylinder or hydraulic cylinder, serving as a lifting drive mechanism 503, is fixedly mounted on the support 501. The vertical output end of the lifting drive mechanism 503 is fixedly connected to the upper end of the bracket 504. A load beam 505 is rotatably mounted on the bracket 504 via a slewing bearing or similar device. The load beam 505 is driven by a motor mounted on the bracket 504, allowing it to rotate about its axis in a vertical plane. When the load beam 505 is in a horizontal working state, its axis is parallel to the length direction of the slide rail 203.

[0044] At least three adjustment parts 506 are circumferentially distributed around the axis of the load-bearing beam 505. Each adjustment part 506 can move synchronously along the radial direction of the load-bearing beam 505. Therefore, the load-bearing beam 505 is a hollow columnar structure. Through holes for the adjustment parts 506 to pass through are provided on the sidewalls of the load-bearing beam 505. The adjustment parts 506 are arranged radially along the load-bearing beam 505. Each adjustment part 506 can be driven by a separate electric actuator, or preferably, they are connected by a linkage mechanism and driven by a common drive source, thereby achieving synchronous and uniform radial movement of all adjustment parts 506. For this purpose, each adjustment part 506 includes a threaded part 509 and a tubular part 510. The tubular part 510 is threadedly connected to the threaded part 509. One of the threaded part 509 or the tubular part 510 extends out of the load-bearing beam 505, and the other is connected to a drive shaft 511 inside the load-bearing beam 505. In this embodiment, the tubular part 510... One end of the tubular part 510 extends out of the load-bearing beam 505 through the through hole, and the outer wall of the tubular part 510 is keyway-fitted with the through hole on the load-bearing beam 505. The other end of the tubular part 510 is provided with a threaded groove that is threaded to one end of the threaded part 509. The other end of the threaded part 509 passes through the bearing seat inside the load-bearing beam 505 and is fixedly connected to the transmission bevel gear. The drive shaft 511 is provided with a drive main gear that meshes with the transmission bevel gear. The drive shaft 511 is coaxially arranged with the load-bearing beam 505 and rotates under the drive of the motor. The end of the adjusting part 506 is equipped with a transmission wheel.

[0045] The end of the load-bearing beam 505 is provided with a baffle 507 that can move radially along it. The baffle 507 can be driven by a hydraulic cylinder or the like installed in the load-bearing beam 505, or by a drive mechanism with the same structure as the drive adjustment part 506. The baffle 507 is a telescopic structure whose length can be adjusted radially along the load-bearing beam 505. For example, the baffle 507 includes a sleeve and a threaded rod. The threaded rod is located outside the sleeve and is threadedly connected to the sleeve. The sleeve is connected to the drive mechanism. The length of the baffle 507 can be adjusted by rotating the threaded rod.

[0046] The load-bearing beam 505 is also provided with a push plate 508, which can move along the axis of the load-bearing beam 505 under the drive of a cylinder, electric push rod, etc. The push plate 508 and the workpiece 4 can be magnetically attracted together, and the push plate 508 can be provided with a pneumatic gripping mechanism to drive the workpiece 4 to move along the axis of the moving load-bearing beam 505.

[0047] The specific working process is as follows: The support 501 moves to the loading and unloading area, the lifting drive mechanism 503 is activated, and the load beam 505 in the horizontal state is driven to descend, so that the height of the load beam 505 is consistent with the height of the workpiece 4 on the conveying part 502; the conveying part 502 drives the workpiece 4 to move towards the load beam 505, so that the load beam 505 is inserted into the workpiece 4 until the baffle 507 extends to the outside of the workpiece 4. The baffle 507 extends outward radially along the load beam 505, forming a limit on the axial movement path of the workpiece 4. In this state, the outer diameter of the baffle 507 is smaller than the outer diameter of the workpiece 4 and larger than the inner diameter of the workpiece 4. At this time, the workpiece 4 is located between the baffle 507 and the push plate 508; after the baffle 507 moves into place, all the adjusting parts 506 move outward synchronously radially along the load beam 505, radially pressing against the inner sidewall of the workpiece 4, completing the automatic centering and pre-clamping of the workpiece 4, and ensuring the coaxiality of the workpiece 4 and the load beam 505. Then, the push plate 508 moves along the axial direction of the load beam 505 toward the baffle 507, pushing the workpiece 4 until its end face abuts against the baffle 507, thus completing the precise positioning of the workpiece 4 on the load beam 505. After the workpiece 4 is fixed, the support 501 rises and moves laterally, transferring the workpiece 4 to the clamping station.

[0048] Longitudinal clamping part clamping process: The load beam 505 carries the workpiece 4 to the platform 102 of the longitudinal clamping part 1. Then, the load beam 505 rotates from the horizontal state to the vertical state (at this time, the baffle 507 is located below the push plate 508). After the load beam 505 rotates to the position, the baffle 507 retracts radially. At this time, the adjusting part 506 keeps radially against the inner wall of the workpiece 4. The push plate 508 pushes the workpiece 4 downward, so that the lower surface of the workpiece 4 extends into the first chuck 107. After the first chuck 107 clamps the workpiece 4, the load beam 505 rises, so that the load beam 505 is pulled out from inside the workpiece 4, completing the clamping of the workpiece 4 on the longitudinal clamping part 1. After the workpiece 4 is welded on the longitudinal clamping part 1, the carrying beam 505 descends and extends into the workpiece 4. After the push plate 508 is connected to the workpiece 4, the adjusting part 506 radially presses against the inner wall of the workpiece 4. At the same time, the baffle 507 extends radially to the outer side of the lower surface of the workpiece 4 to support the lower surface of the workpiece 4. Then the first chuck 107 releases the workpiece 4, and the carrying beam 505 carries the workpiece 4 to a transverse position. Then it is moved to the top of the conveying part 502. Then the carrying beam 505 descends and places the workpiece 4 on the conveying part 502. The adjusting part 506 and the baffle 507 retract radially, thereby separating from the workpiece 4. The conveying part 502 runs in the opposite direction to the feeding direction, so that the workpiece 4 is completely separated from the carrying beam 505, and the unloading is completed.

[0049] The clamping process of the transverse clamping part is as follows: The load beam 505 carries the workpiece 4 and moves it until the workpiece 4 is coaxially set with the rotary disk 301. The push plate 508 pushes the workpiece 4 to move axially toward the rotary disk 301, so that the workpiece 4 extends into the clamping device 302. After the clamping device 302 clamps the workpiece 4, the load beam 505 is pulled out axially, so that the load beam 505 is disengaged from the inside of the workpiece 4, and the clamping of the workpiece 4 on the transverse clamping part is completed. After the workpiece 4 is welded on the transverse clamping part, the carrying beam 505 extends axially back into the workpiece 4. After the push plate 508 is connected to the workpiece 4 and the adjusting part 506 radially abuts against the inner side wall of the workpiece 4, the clamping device 302 releases the workpiece 4. The carrying beam 505 carries the workpiece 4 to the top of the conveying part 502. The carrying beam 505 descends and places the workpiece 4 on the conveying part 502. The adjusting part 506 and the baffle 507 retract radially, thereby separating from the workpiece 4. The conveying part 502 runs in the opposite direction to the feeding direction, so that the workpiece 4 is completely separated from the carrying beam 505, completing the unloading.
