Description

Technical Field

[0001] The invention relates to the technical field of laser welding of special-shaped components, in particular to a laser welding rapid adjustment platform suitable for special-shaped components. Background Art

[0002] Special-shaped components are workpieces with irregular geometries, asymmetric structures, or multi-curved connection features, and are commonly found in industries such as aviation, automotive, rail transportation, and high-end equipment manufacturing. These components often include variable cross-sections, spatially curved joints, and non-standard assembly interfaces. They are complex, require high precision, and are challenging to process and assemble. Laser welding, with its advantages of high energy density, non-contact processing, minimal deformation, and narrow heat-affected zone, has become a key method for connecting special-shaped components in existing manufacturing processes.

[0003] After searching, the invention patent with publication number CN118342177A discloses an automatic adjustment and measurement device for welding special-shaped steel components, which realizes automatic measurement and welding of special-shaped steel components, automatically obtains steel structure deepening model data, and performs visual review.

[0004] When welding special-shaped pipe components (such as branch pipes at different angles and directions), manual alignment of the welding interface is often required. Especially when there is an offset or error in the direction of the pipe component, the fit and alignment are very likely to be misaligned, seriously affecting the consistency and quality of the weld. During continuous girth welding, excessive heat is concentrated in a local area, resulting in the expansion of the weld heat-affected zone, embrittlement of the material structure, and even deformation of the weld area. Summary of the Invention

[0039] 2. Since the fitting sleeve fits the pipe component and is hinged with the electric push rod, the fitting sleeve rotates with the pipe component. There is no need to adjust the angle of the welding unit again. The fitting sleeve is self-adaptive and the two clamps and the inclined support seat can slide. After the pipe component is welded, the clamp block is hidden in the groove cavity of the transmission plate, and the inclined support seat is de-energized by the electromagnet and retracted into the groove cavity of the limiting plate. The fitting sleeve slides away from the welding end of the main pipe component, exits the fitting state, and is completely separated from the pipe component, repeating the positioning of the next station.

[0040] 3. By setting up the pushing unit, after the pipe component is sent to contact the stop block, the rotating clamping block will align the welding end face of the pipe component with the welding interface of the main pipe component. Then, when the electric push rod is started, the push block will rise and slide horizontally along with the electric push rod to push the pipe component to fit accurately.

[0051] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0052] See also Figures 1-8 As shown, the present invention provides a laser welding rapid adjustment platform suitable for special-shaped components, comprising a processing table 1, a welding chamber 2 is provided in the middle of the processing table 1, and a slide 10 is slidably provided on a track on the bottom surface of the processing table 1, and two welding stations 4 for alternating laser welding are installed on the slide 10;

[0053] The outer walls of both sides of the processing table 1 are provided with a loading unit that communicates with the inner cavity of the welding chamber 2;

[0054] The central surface of the welding station 4 is provided with an insertion groove 5 for use with the main component, and both sides of the insertion groove 5 are provided with a docking transfer unit that slides closer or farther away;

[0055] The docking transfer unit includes a transmission plate 12, the side of which is fixedly connected to a limiting plate 26 that slides along the top surface of the welding station 4. The edge of the groove cavity on the upper surface of the limiting plate 26 is provided with a stopper 14 for limiting the edge of the pipe member, and two inclined brackets 27 are slidably provided in the groove cavity on the upper surface of the limiting plate 26 for supporting the pipe member.

[0056] An alignment unit for aligning the end of the pipe member with the main pipe member is rotatably provided in the groove cavity on the upper surface of the transmission plate 12. The alignment unit includes a push seat 24 symmetrically slidably embedded on the inner walls of both sides of the transmission plate 12. A clamping block 15 that fits the pipe member is rotatably connected to one side surface of the push seat 24.

[0057] The inner cavity of the welding chamber 2 is slidably provided with two welding units that rise and fall in the vertical direction and rotate with the corresponding pipe components;

[0058] The welding unit includes a fitting sleeve 31, and a laser head 34 for annular welding of the connection is provided on the side of the fitting sleeve 31;

[0059] Use jump section laser welding, first laser weld the joint 0-90 degrees;

[0060] Then jump to weld 180-270 degrees;

[0061] Finally, repair weld the remaining interval areas. There is a cooling buffer after each section of welding. Interval welding allows the previous weld to have time to cool down, and the heat is distributed more evenly.

[0062] When welding special-shaped parts, the previous main component enters the welding chamber 2, and the pipe component is fed by the loading unit so that it accurately fits the welding interface of the main component;

[0063] Another main component is placed in the insertion groove 5 in the welding station 4, and the welding interface of the main component is exposed at the designated position on the upper part. The main component is alternately moved to the welding chamber 2 after the previous welding process is completed during the welding interval to improve the processing efficiency.

[0064] During laser welding in the welding chamber 2, the welding station 4 enters the welding chamber 2 to ensure that the loading unit and the docking transfer unit are in a collinear position;

[0065] In the initial state, the two transmission plates 12 are in a state of being away from each other, that is, adjacent to the loading unit on the corresponding side, and the stopper 14 on the limiting plate 26 is in a state of being raised and opened;

[0066] The welding unit is initially in an ascending state. After the welding station 4 reaches the welding chamber 2, the fitting sleeve 31 in the welding unit is pushed downward, descends, and enters the groove cavity on the upper surface of the limiting plate 26, that is, between the inclined support seat 27 and the stopper 14.

[0067] The pipe member enters from the loading unit, passes through the interior of the two clamping blocks 15, reaches the groove cavity on the upper surface of the limiting plate 26, and fits through the interior of the fitting sleeve 31. The pipe member is supported by the inclined supports 27 on both sides until one end of the pipe member contacts the stopper 14.

[0068] Then, the two driving plates 12 approach each other, and the pipe component is pushed to the preset welding interface area of ​​the main pipe component. Then, the stopper 14 descends and resets to release the axial restriction. Then, the clamping block 15 clamps the pipe component and rotates it to keep the welding surface of the pipe component end aligned with the welding interface of the main pipe component, thereby improving the welding quality and consistency.

[0069] The pipe component is fitted with the fitting sleeve 31, and driven by the clamping block 15, the fitting sleeve 31 is rotated together. The automatic alignment process does not require manual intervention, which is suitable for rapid welding preparation of batch special-shaped components and improves the efficiency of pre-welding preparation.

[0070] Laser welding adopts jump section welding. First, the first section of laser welding is performed on the 0° to 90° section of the welding interface between the pipe component and the main pipe component.

[0071] Subsequently, the laser head 34 jumps to the 180° to 270° section of the opposite area to perform the second section of laser welding;

[0072] Allow the previous weld section to have sufficient cooling time before welding the next section, reduce heat accumulation, complete closed-loop repair welding in the remaining unwelded area between the two weld areas, and achieve a complete annular weld connection;

[0073] After welding is completed, the oblique brackets 27 on both sides are hidden in the groove cavity on the upper surface of the limiting plate 26;

[0074] The clamping block 15 is synchronously hidden in the groove cavity on the upper surface of the transmission plate 12, and then the fitting sleeve 31 slides away from the welding end of the main pipe component, exits the fitting state, and is completely separated from the pipe component.

[0075] See Figure 6 As shown, an electromagnet 28 is embedded in the groove cavity on the upper surface of the limiting plate 26, and the armature in the electromagnet 28 is fixed to the linear surface of the oblique bracket 27;

[0076] Initially, the oblique supports 27 on both sides are in the expanded state, supporting the lower surface of the pipe component through the oblique surface. When the welding is completed, the electromagnet 28 is powered off and released, and the armature drives the oblique support 27 to retract along the set direction under the action of the elastic member, and finally is stored in the groove cavity on the upper surface of the limiting plate 26, completing the automatic reset of the supporting structure.

[0077] See Figure 7 and Figure 8As shown, a linear guide rail 29 is provided at the top of the inner cavity of the welding chamber 2, and a second electric push rod 30 is installed on the slide seat of the linear guide rail 29. The pushing end of the second electric push rod 30 is connected to the fitting sleeve 31 through a damping pin shaft;

[0078] The welding unit also includes an annular seat 35 provided on the side of the fitting sleeve 31. A gear sleeve 33 is provided on the sliding sleeve of the annular seat 35. A driving gear 32 driven by a driving motor and meshing with the gear sleeve 33 is installed on the side edge of the fitting sleeve 31.

[0079] The laser head 34 is mounted on the side of the gear sleeve 33;

[0080] Since the fitting sleeve 31 is hinged to the pushing end of the electric push rod 2 30 via a damping pin, the fitting sleeve 31 can float along with the angle of the pipe component and adjust its posture synchronously to maintain fitting with the outer wall of the pipe component;

[0081] During welding, the driving gear 32 drives the gear sleeve 33 to slide around the annular seat 35 and drives the laser head 34 to perform jump welding on the connection, that is, first welding the connection at 0-90 degrees; then jumping to welding at 180-270 degrees, and then repair welding the remaining positions.

[0082] See Figure 5 As shown, the alignment unit further includes a synchronous cylinder 23 embedded on the inner wall of the transmission plate 12, a rotary motor 25 is installed on the pushing end of the synchronous cylinder 23, and the driving end of the rotary motor 25 is fixed to the clamping block 15;

[0083] Initially, the axis of the two clamping blocks 15 is consistent with the center of the loading unit. After welding, the synchronous cylinder 23 pushes the clamping blocks 15 synchronously, improving the automation level and execution response speed of the welding system;

[0084] The surface of the push seat 24 is provided with an arc-shaped slot, and the clamping block 15 is provided with a clamping block that slides in the arc-shaped slot;

[0085] Driven by the rotating motor 25, the clamping block 15 can accurately adjust the angle of the pipe component, cooperate with the alignment of the fitting sleeve 31 and the weld, and improve the positioning accuracy before welding. When the clamping block 15 rotates, the clamping block slides in the arc-shaped slot to ensure the stability of its movement.

[0086] See Figure 3 As shown, a side plate 13 is installed on the side of the transmission plate 12, and a pushing unit that slides along the pushing direction is provided on the edge of the side plate 13;

[0087] The pushing unit includes an electric push rod 16 which is slidably arranged in the inner cavity of the edge of the side plate 13, and a push block 17 is installed at the pushing end of the electric push rod 16;

[0088] During operation, after the pipe component is sent to contact the stopper 14, the rotating clamping block 15 first aligns the welding end face of the pipe component with the welding interface of the main pipe component, and then the electric push rod 16 is started. At this time, the push block 17 rises, and the push block 17 slides horizontally along the electric push rod 16 and pushes the pipe component to fit accurately.

[0089] After the material is pushed, the electric push rod 16 retracts and the push block 17 returns to its original position, waiting for the next round of feeding.

[0090] See Figure 1 As shown, the feeding unit includes a feeding cylinder 6, the upper surface of which is provided with an opening, and a circular push plate is installed inside the feeding cylinder 6 to push the pipe member to move by the pushing cylinder;

[0091] The pipe components are placed from the opening, and pushed by the circular push plate, the pipe components enter in sequence.

[0092] See Figure 2 and Figure 4 As shown, an input port 7 is provided on both side edge surfaces of one end of the processing table 1, and an output port corresponding to the input port 7 is provided on the other end of the processing table 1. Conveyor strips 8 are installed on both sides of the inner walls of the input port 7 and the output port;

[0093] The edges of both sides of the top surface of the welding station 4 are provided with a conveyor belt 2 18 that is at the same height and in line with the conveyor belt 1 8, and a material moving unit is installed at the edge of the conveyor belt 2 18;

[0094] Both conveyor belt 2 18 and conveyor belt 1 8 are provided with pads that contact the main pipe component;

[0095] The main component naturally transitions to the co-linear conveyor belt 2 18 at the end of the conveyor belt 1 8, achieving smooth access to the welding station 4;

[0096] The outer wall of the welding chamber 2 is equipped with a transfer rack 3, and the bottom surface of the transfer rack 3 is rotatably equipped with a claw for grabbing the main pipe parts;

[0097] The inner wall surface of the limiting plate 26 is provided with an insertion groove for the claw hand to enter;

[0098] The main component is moved to the end by the conveyor belt 2 18, and is clamped by the claw hand and placed into the insertion groove 5 through the insertion groove;

[0099] The material transfer unit includes a sliding rail 21 that slides in the horizontal direction and is driven by a reciprocating cylinder. A lifting electric cylinder 20 is slidably provided on the sliding rail 21. The driving end of the lifting electric cylinder 20 is provided with a transfer support 19 that lifts the main component.

[0100] During loading, the conveyor belt 2 18 in the welding station 4 is kept in line with the conveyor belt 1 8, and the main component is transferred from the conveyor belt 1 8 to the conveyor belt 2 18 through the material transfer unit, thereby realizing the automatic transfer of the main component;

[0101] After welding is completed, the main component is moved to the conveyor belt 2 18 on the other side by the claw hand and moved out from the conveyor belt 1 8 on the output side.

[0102] See Figure 2 and Figure 4 As shown, a channel 22 communicating with the grooves of the transmission plate 12 and the limiting plate 26 is provided below the conveyor belt 2 18;

[0103] The channel 22 moves along with the welding station 4 to the interior of the welding chamber 2 and communicates with the feeding tube 6;

[0104] A bidirectional screw 9 threadably sleeved with two transmission plates 12 is provided inside the welding station 4 .

[0105] After the pipe member enters from the feeding tube 6, it first passes through the channel 22. Since the transmission plate 12 is close to the channel 22 on the corresponding side, it then enters the two clamping blocks 15 until one end contacts the stopper 14. Then, the two transmission plates 12 approach each other under the thread drive of the bidirectional screw 9, so that the limiting plate 26 is consistent with the axis of the insertion groove 5, completing the restriction of the main pipe member and avoiding shaking during welding.

[0106] See Figure 2 As shown, a rubber roller 11 driven by a servo motor is embedded in the inner wall of the insertion groove 5. The rubber roller 11 contacts the main body component and is used to drive the main body component to rotate.

[0107] After the main member is placed in the insertion groove 5, the rubber roller 11 starts to rotate under the drive of the servo motor. The friction between the rubber roller 11 and the outer wall of the main member drives the main member to realize controllable rotation around its axis until the two welding interfaces of the main member are symmetrical with the central vertical axis of the insertion groove 5. The rotation positioning of the main member is completed.

[0108] When the present invention is in use, by setting a sliding docking transfer unit and a rotating alignment unit, the fitting sleeve 31 descends and enters between the oblique support seat 27 and the stopper 14 in the groove cavity of the limiting plate 26, and the pipe member enters from the feeding unit, passes through the interior of the two clamping blocks 15, reaches the groove cavity on the upper surface of the limiting plate 26, and fits through the interior of the fitting sleeve 31. The oblique support seats 27 on both sides support the pipe member until one end thereof contacts the stopper 14; then, the two transmission plates 12 approach each other, and the pipe member is pushed to the preset welding position of the main pipe member. In the interface area, the stopper 14 then descends and resets to release the axial restriction. The clamping block 15 clamps the pipe component and rotates to keep the welding surface of the pipe component end aligned with the welding interface of the main pipe component, improving the welding quality and consistency. Automatic alignment requires no manual intervention, which improves the efficiency of pre-welding preparation. The welding adopts jump welding, first laser welding the connection at 0-90 degrees, then jump welding 180-270 degrees, and finally repair welding the remaining interval areas. There is a cooling buffer after each section is welded. The interval welding allows the previous section weld to have cooling time, and the heat is more evenly distributed.

[0109] The fitting sleeve 31 is fitted with the pipe member and is hinged with the electric push rod 2 30. The fitting sleeve 31 rotates along with the pipe member, and there is no need to adjust the angle of the welding unit again. The two clamping blocks 15 and the oblique support seat 27 can slide. After the pipe member is welded, the clamping block 15 is hidden in the groove cavity of the transmission plate 12, and the oblique support seat 27 is de-energized by the electromagnet 28 and retracted into the groove cavity of the limiting plate 26. The fitting sleeve 31 slides in a direction away from the welding end of the main pipe member, exits the fitting state, and is completely separated from the pipe member, repeating the positioning of the next station;

[0110] By setting up the pushing unit, after the pipe component is sent to contact the stopper 14, the rotating clamping block 15 will align the welding end face of the pipe component with the welding interface of the main pipe component, and then the electric push rod 16 will be started. At this time, the push block 17 will rise, and the push block 17 will slide horizontally along the electric push rod 16 to push the pipe component to fit accurately.
