Abstract

This invention discloses a laser welding device with an adaptive clamping mechanism, belonging to the field of welding equipment technology. It includes a worktable, a laser welding head, an angle-contouring base, and a horizontal bar-type floating clamp assembly. The angle-contouring base supports the box body, and the horizontal bar-type floating clamp assembly spans above the box body. The end floating clamps in the horizontal bar-type floating clamp assembly clamp the box body and the partition. A floating slide slides along the horizontal bar.

Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a laser welding device equipped with an adaptive clamping mechanism. Background Technology

[0002] Laser welding equipment typically uses a worktable to support the workpiece and a laser welding head to weld the area to be welded along a predetermined trajectory. For box-type parts, especially box structures with internal partitions, the connection between the partition and the inner wall of the box usually forms a fillet weld. This type of weld is located inside the box, and the welding space is limited by the height of the box wall and the partition.

[0003] Existing fixtures often clamp the box from the outside or a local position, making it difficult to simultaneously achieve stable positioning of the welding areas on the end face of the partition, the top of the partition, and the sides of the partition. When there are processing errors in the internal cavity size of the box, the height of the partition, or the assembly position of the partition, the fixed clamping parts are prone to problems such as insufficient local clamping or excessive rigid pressure, which in turn leads to inconsistency between the laser port and the actual weld position.

[0004] Meanwhile, existing fixtures are usually independent of the movement path of the laser welding head. When the welding head moves along the weld, the clamping and limiting structures near the weld are difficult to move synchronously. If there are slight height changes or weld boundary changes in the welding area, the continuity of the weld and the welding quality can be easily affected.

[0005] Therefore, it is necessary to invent a laser welding device with an adaptive clamping mechanism to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a laser welding device with an adaptive clamping mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a laser welding device with an adaptive clamping mechanism, comprising a worktable, a laser welding head, an angle-contouring base, and a horizontal bar floating clamp assembly. The angle-contouring base is disposed on the worktable and is used to support the component to be welded. The component to be welded includes a box body and a partition disposed within the box body. The horizontal bar floating clamp assembly includes a horizontal bar, end floating clamps, a floating slide, a floating seat, a pressure roller, two sets of weld seam contouring clamps, a traction connector, and a traction cooperating component. The horizontal bar spans above the box body. The end floating clamps are respectively disposed at both ends of the horizontal bar and clamp the box body. The end floating clamps are provided with partitions for clamping the partitions. The plate has a floating slide seat slidably mounted on the crossbar. The floating seat is mounted on the floating slide seat and presses against the top of the partition. Two sets of weld seam conforming clamps are symmetrically arranged on both sides of the partition. The weld seam conforming clamps are close to the connection between the box body and the partition and have welding clearance grooves corresponding to the laser port of the laser welding head. The traction connector is fixed in the middle of the outer surface of one set of the two sets of weld seam conforming clamps. The traction mating member is mounted on the laser welding head and is inserted and mated with the traction connector. The laser welding head drives the floating slide seat and the two sets of weld seam conforming clamps to slide along the crossbar through the traction mating member and the traction connector.

[0008] Furthermore, the floating seat, spring guide assembly, pressure roller, and two sets of weld seam contouring fixtures together constitute an adaptive clamping mechanism. The spring guide assembly enables the floating seat to have an elastic floating stroke relative to the floating slide. The pressure roller is used to press against the top of the partition. The two sets of weld seam contouring fixtures are respectively used to approach the welding areas on both sides of the partition, so that the clamping above the partition and the contouring limit on both sides of the weld seam can be positionally compensated according to the local size changes of the box and the partition.

[0009] Furthermore, the angle-conforming base is supported on an angle support seat, the angle support seat has a support surface that is inclined relative to the worktable, and a box positioning block is provided on the angle-conforming base, the box positioning block being pressed against the outer side of the end of the box.

[0010] Furthermore, the end floating clamp includes an outer overlapping buckle, a clamp seat, the partition clamping plate, a clamping push block, and a clamping adjustment member. The outer overlapping buckle is disposed at one end of the clamp seat facing the outside of the box body, the partition clamping plate is disposed on the side of the clamp seat facing the partition, and the clamping adjustment member is in a driving cooperation with the clamping push block to make the partition clamping plate press against the partition.

[0011] Furthermore, a height adjustment rod is fixed on the end floating clamp, and an end slide is provided at the end of the crossbar. The end slide is sleeved on the height adjustment rod and locked by fasteners.

[0012] Furthermore, the floating seat includes a floating connecting plate, a spring guide assembly, and a vertical guide plate. The floating connecting plate is connected to the floating slide via the spring guide assembly, and the vertical guide plate is disposed below the floating connecting plate and connected to the weld seam conforming fixture.

[0013] Furthermore, the floating seat also includes a hinged arm, a swing seat, and a hinged locking member. The hinged arm is hinged to the swing seat, and the hinged locking member is disposed at the hinge point between the hinged arm and the swing seat. The pressure roller is rotatably disposed at the lower end of the swing seat and located directly above the partition plate.

[0014] Furthermore, each set of weld seam conforming fixtures includes a conforming slide, a first slipper, a second slipper, and a welding clearance groove. The first slipper and the second slipper are respectively disposed on the side of the conforming slide facing the box and the partition, and the welding clearance groove is located between the first slipper and the second slipper.

[0015] Furthermore, the traction connector is a guide block with an inclined guide surface at the end, the traction connector is fixed to the middle of the outer surface of the contour slide, and the traction mating part is an open sleeve fixed to the side of the laser welding head, the open sleeve having an insertion interface facing the guide block.

[0016] Furthermore, after the traction connector is inserted into the traction mating member, the laser port of the laser welding head is located above the welding clearance groove, and the light emission direction of the laser port is towards the connection between the box and the partition.

[0017] Furthermore, the crossbar extends along the length of the partition, the sliding direction of the floating slide is consistent with the extension direction of the connection between the box and the partition, and the welding clearance groove passes through the weld contouring fixture along the sliding direction of the floating slide.

[0018] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up an angle-contouring base, a crossbar, an end floating clamp, a floating slide, a floating seat, a pressure roller, and two sets of weld seam contouring clamps, enables the box body to form a stable support on the angle-contouring base. The crossbar can straddle the box body and serve as a sliding reference extending along the weld seam direction. The end floating clamp clamps the box body and the partition at the end, and the pressure roller presses the partition above. The two sets of weld seam contouring clamps are located on both sides of the partition and close to the connection between the box body and the partition. This forms a continuous positioning chain for the end face positioning before welding, the upper pressing during welding, and the limiting of the weld seam on both sides. This helps to reduce the offset of the partition relative to the box body and improve the consistency of the fillet weld welding position. 2. This invention, by setting up a spring guide assembly, a floating connecting plate, a vertical guide plate, a hinge arm, a swing seat, a hinge locking component, and a pressure roller, enables the pressure roller to press against the top of the partition in the posture limited by the swing seat. The spring guide assembly enables the floating seat to have an elastic compensation stroke along the direction of the guide rod. During the welding process, when there are slight differences in the height of the partition, the position of the inner wall of the box, or the weld boundary, the pressure roller and the weld contouring fixture can maintain contact within the elastic floating range, thereby forming an adaptive pressing effect, reducing the possibility of local deformation of the partition caused by rigid top pressure and improving the stability of gap control in the welding area. 3. The present invention sets up a contouring slide, a first slide, a second slide, and a welding clearance groove in the weld contouring fixture, so that the first slide and the second slide are close to the two side boundaries of the connection between the box and the partition. The contouring slide plays the role of slide installation and weld direction guidance during the movement. The welding clearance groove provides a through light output space for the laser port, thereby ensuring that the slide is close to the welding area while avoiding blocking the laser beam, which is beneficial to improving the correspondence accuracy between the weld contouring limit and the laser welding path. 4. This invention fixes the traction connector to the middle of the outer surface of the weld contouring fixture and sets a traction mating component on the laser welding head. When the laser welding head reaches the welding start position, it can complete the insertion and mating with the guide block with the inclined guide surface at the end through the open sleeve. During the welding process, the laser welding head drives the weld contouring fixture and the floating slide to slide synchronously along the crossbar through the traction mating component and the traction connector. This keeps the welding clearance groove and the laser port aligned, reducing the deviation between the laser head movement path and the weld contouring limit path. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 10As shown, the laser welding equipment with an adaptive clamping mechanism provided by the present invention essentially establishes a floating clamping and contouring support structure that can move with the welding path at the position where the fillet weld is formed between the box 3 and the partition 31, so that the laser welding head 11 synchronously pulls the weld contouring fixture 46 to slide along the weld extension direction during the movement.

[0032] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitations are imposed.

[0033] In this embodiment, a laser welding device with an adaptive clamping mechanism includes a worktable 1, a laser welding head 11, an angle contouring base 2, and a horizontal bar floating clamp assembly 4. The worktable 1 is used to support the angle contouring base 2 and the laser welding operation area. The laser welding head 11 is disposed above the worktable 1 and can move along the extension direction of the weld seam to be welded. The angle contouring base 2 is disposed on the worktable 1 and is used to support the box body 3.

[0034] Angle contour base 2 is supported on angle support base 21. Angle support base 21 has a support surface that is inclined relative to worktable 1. After box 3 is placed on angle contour base 2, the connection between the partition 31 inside box 3 and box 3 faces the laser port of laser welding head 11. Box positioning pressure block 22 is set on angle contour base 2 and presses against the outer side of the end of box 3, so that box 3 forms a stable bottom support and end positioning before welding.

[0035] The box body 3 is the workpiece to be welded. The partition 31 is set inside the box body 3. The end face of the partition 31 and the inner wall of the box body 3 form a fillet weld to be welded. The length direction of the partition 31 serves as the sliding reference direction for the crossbar 41, the floating slide 43 and the weld contouring fixture 46 in this embodiment.

[0036] The horizontal bar floating clamp assembly 4 includes a horizontal bar 41, an end floating clamp 42, a floating slide 43, a floating seat 44, a pressure roller 45, two sets of weld seam conforming clamps 46, a traction connector 47, and a traction mating component 48. The horizontal bar 41 spans above the box body 3 and extends along the length of the partition 31. The two ends of the horizontal bar 41 are respectively connected and clamped to the box body 3 by the end floating clamp 42, so that the horizontal bar 41 can form a sliding support structure above the partition 31 with the box body 3 as the installation reference.

[0037] The end floating clamp 42 includes an outer overlapping buckle 421, a clamp seat 422, a partition clamping plate 423, a clamping push block 424, and a clamping adjustment member 425. The outer overlapping buckle 421 is located at the end of the clamp seat 422 facing the outside of the box body 3 and overlaps the outer edge of the box body 3. The partition clamping plate 423 is located on the side of the clamp seat 422 facing the partition 31. After the clamping adjustment member 425 and the clamping push block 424 are in transmission cooperation, the partition clamping plate 423 is pushed to press the partition 31, thereby locking the position of the connection between the end face of the box body 3 and the partition 31.

[0038] A height adjustment rod 412 is fixed on the end floating clamp 42. An end slide 411 is provided at the end of the crossbar 41. The end slide 411 is sleeved on the height adjustment rod 412. After the fastener is loosened, the position of the end slide 411 relative to the height adjustment rod 412 can be adjusted. After the adjustment is completed, the crossbar 41 is locked relative to the end floating clamp 42 by the fastener to keep it in a fixed installation state.

[0039] The floating slide 43 is slidably mounted on the crossbar 41. The floating slide 43 can move along the length of the crossbar 41. The floating seat 44 is mounted on the floating slide 43 and moves synchronously with the floating slide 43. The floating seat 44 is used to support the pressure roller 45 and the weld seam contouring fixture 46, so that the pressing position of the pressure roller 45 and the contouring limit position of the weld seam contouring fixture 46 can change synchronously with the welding path.

[0040] In this embodiment, the adaptive clamping mechanism is composed of a floating slide 43, a floating seat 44, a spring guide assembly 442, a hinge arm 443, a swing seat 444, a hinge locking member 445, a pressure roller 45, and two sets of weld seam contouring clamps 46. The floating slide 43 provides a base for sliding along the crossbar 41, the floating seat 44 provides a common mounting base for the pressure roller 45 and the weld seam contouring clamps 46, the spring guide assembly 442 provides elastic compensation stroke along the clamping direction, the pressure roller 45 provides rolling clamping above the partition 31, and the two sets of weld seam contouring clamps 46 provide weld seam contouring limits on both sides of the partition 31.

[0041] The floating seat 44 includes a floating connecting plate 441, a spring guide assembly 442, and a vertical guide plate 446. The spring guide assembly 442 includes a guide rod and a spring. The guide rod is disposed between the floating slide 43 and the floating connecting plate 441 and is used to limit the floating direction of the floating seat 44 relative to the floating slide 43. The spring is sleeved on the outside of the guide rod or abuts against the periphery of the guide rod. One end of the spring acts on the floating slide 43, and the other end of the spring acts on the floating connecting plate 441, so that the floating seat 44 has an elastic pressing stroke relative to the floating slide 43. The vertical guide plate 446 is disposed below the floating connecting plate 441 and is connected to the weld seam conforming fixture 46.

[0042] The floating seat 44 also includes a hinge arm 443, a swing seat 444, and a hinge locking member 445. The hinge arm 443 is hinged to the swing seat 444. The swing seat 444 adjusts the installation angle relative to the hinge arm 443 through the hinge. The hinge locking member 445 is provided at the hinge of the hinge arm 443 and the swing seat 444 and is used to lock the relative position of the two. The pressure roller 45 is rotatably provided at the lower end of the swing seat 444 and located directly above the partition 31, so that the pressure roller 45 can apply a pressing force to the upper surface of the partition 31 in a rolling contact manner.

[0043] The pressure roller 45 presses against the top of the partition 31, and does not directly press against the side wall of the box 3. During the welding process, the pressure roller 45 moves along the length of the partition 31 with the floating seat 44 and the floating slide 43. The spring guide assembly 442 compresses or rebounds when there are slight fluctuations in the height of the partition 31, so that the pressure roller 45 maintains contact with the top of the partition 31 and avoids excessive local stress on the partition 31 due to rigid pressing.

[0044] Two sets of weld contouring fixtures 46 are symmetrically arranged on both sides of the partition 31. Each set of weld contouring fixtures 46 includes a contouring slide 461, a first slide shoe 462, a second slide shoe 463, and a welding clearance groove 464. The first slide shoe 462 is located on the side of the contouring slide 461 facing the box 3, and the second slide shoe 463 is located on the side of the contouring slide 461 facing the partition 31. The welding clearance groove 464 is located between the first slide shoe 462 and the second slide shoe 463 and slides along the sliding direction of the floating slide 43. The welding clearance groove 464 passes through the contouring slide 461 along the sliding direction of the floating slide 43 to the through weld seam contouring fixture 46. The welding clearance groove 464 is located between the first slide shoe 462 and the second slide shoe 463. The groove opening of the welding clearance groove 464 corresponds vertically to the laser port of the laser welding head 11. The groove width of the welding clearance groove 464 is larger than the laser beam action area, so that the first slide shoe 462 and the second slide shoe 463 can be close to the connection between the box 3 and the partition 31 and avoid blocking the laser beam.

[0045] The contour slide 461 serves as the main load-bearing component of the weld contour clamp 46. In this embodiment, it is made of stainless steel to ensure that the contour slide 461 maintains sufficient structural rigidity when bearing the traction force transmitted by the traction connector 47, and can stably support the first slide shoe 462, the second slide shoe 463, and the welding clearance groove 464. The first slide shoe 462 and the second slide shoe 463 are sliding components that contact the box body 3 and the partition plate 31 near the weld area. In this embodiment, they are made of polyetheretherketone wear-resistant material. The contact surfaces of the first slide shoe 462 and the second slide shoe 463 are rounded transition surfaces to reduce scratches on the surfaces of the box body 3 and the partition plate 31 during the movement along the weld, and to reduce the frictional resistance when the weld contour clamp 46 slides.

[0046] When the weld seam contouring fixture 46 is working, the first slipper 462 is close to the inner wall of the box 3 or the support surface of the box 3 near the weld seam, and the second slipper 463 is close to the side of the partition 31 or the support surface of the partition 31 near the weld seam. The contouring slide 461, as the load-bearing structure of the two sets of slippers, moves along the weld seam direction. The first slipper 462 and the second slipper 463 together define the position boundaries on both sides of the weld seam. The welding clearance groove 464 is located below the laser port of the laser welding head 11, so that the laser beam can act on the connection between the box 3 and the partition 31 through the welding clearance groove 464.

[0047] During the adaptive clamping process, the spring guide assembly 442 enables the floating seat 44 to have elastic stroke in the clamping direction, the pressure roller 45 provides continuous pressure above the partition 31, and the first slipper 462 and the second slipper 463 provide contouring and limiting at both sides of the connection between the box 3 and the partition 31. When there are processing deviations in the inner wall of the box 3, the side of the partition 31, or the upper surface of the partition 31, the floating seat 44 performs micro-displacement compensation through the spring guide assembly 442, and the pressure roller 45 and the two sets of weld contouring fixtures 46 can still maintain contact and limiting of the welding area.

[0048] In this embodiment, the pressure roller 45 is rotatably mounted on the lower end of the swing seat 444 via a rotating shaft. The outer circumferential surface of the pressure roller 45 is an arc contact surface. The pressure roller 45 only presses against the upper part of the partition plate 31. When the floating slide 43 moves along the crossbar 41, the pressure roller 45 can move synchronously with the floating seat 44 and roll relative to the partition plate 31, thereby reducing the dragging effect of the pressure roller 45 on the partition plate 31.

[0049] One set of weld seam contouring fixtures 46 has a traction connector 47 fixed in the middle of its outer surface. Specifically, the traction connector 47 is fixed in the middle of the outer surface of the contouring slide 461. The traction connector 47 is a guide block with an inclined guide surface at its end. The traction mating part 48 is fixed to the side of the laser welding head 11 and is configured as an open sleeve with an insertion interface. When the laser welding head 11 moves to the welding start position, the traction mating part 48 is inserted into the traction connector 47 through the insertion interface along the inclined guide surface. After the traction connector 47 is inserted into the traction mating part 48, the traction connector 47 and the traction mating part 48 form a traction contact in the welding movement direction, so that the laser welding head 11 can drive the weld seam contouring fixture 46 to move along the crossbar 41.

[0050] After the traction connector 47 is inserted into the traction mating part 48, the laser port of the laser welding head 11 is located above the welding clearance groove 464, and the laser light emission direction of the laser port is towards the connection between the box 3 and the partition 31. When the laser welding head 11 moves along the weld direction, it drives the corresponding weld contouring fixture 46 to move through the traction mating part 48 and the traction connector 47, and the two sets of weld contouring fixtures 46 slide synchronously along the crossbar 41 through the floating seat 44 and the floating slide 43.

[0051] During use, the box body 3 is first placed on the angle contour base 2, and the outer side of the end of the box body 3 is positioned by the box body positioning block 22. Then, the crossbar 41 is straddled above the box body 3, so that the end floating clamps 42 overlap the two ends of the box body 3 respectively and the partition clamping plate 423 clamps the partition 31. Then, the position of the pressure roller 45 relative to the partition 31 is adjusted so that the pressure roller 45 presses against the partition 31, and the two sets of weld contour clamps 46 are located on both sides of the partition 31 respectively.

[0052] During the welding process, the laser welding head 11 moves to the welding start position, and the traction mating part 48 and the traction connecting part 47 are inserted and coupled. The laser port of the laser welding head 11 is directly facing the welding clearance groove 464. Then, the laser welding head 11 moves along the connection between the box body 3 and the partition 31. The traction connecting part 47 transmits the traction force to the weld seam contouring fixture 46. The weld seam contouring fixture 46 is limited along the welding area by the first slipper 462 and the second slipper 463. The pressure roller 45 continuously presses against the top of the partition 31. The spring guide assembly 442 performs elastic compensation according to the local position change at the connection between the partition 31 and the box body 3, so that the welding area remains relatively stable during the moving welding process.

[0053] In summary, the present invention supports the box body 3 through the angle contour base 2, establishes a clamping reference above the box body 3 through the crossbar 41 and the end floating clamp 42, forms an adaptive clamping mechanism through the floating seat 44, the spring guide assembly 442, the swing seat 444 and the pressure roller 45, performs contouring and limiting of the weld area on both sides of the partition 31 through two sets of weld contour clamps 46, and enables the laser welding head 11 to drive the weld contour clamps 46 to move synchronously through the traction connector 47 and the traction cooperating component 48, thereby improving the clamping adaptability, positioning stability and welding consistency during the corner weld welding process between the box body 3 and the partition 31.

[0054] It should be noted that the weld seam conformal fixture 46 and pressure roller 45 in this embodiment are mainly used to cover the middle welding area at the connection between the box body 3 and the partition 31. Since the end of the partition 31 is close to the end floating fixture 42 and the partition clamping plate 423, the end area has the problem of the clamping structure occupying space and the space for the welding head to enter and exit being limited. Therefore, this embodiment mainly completes the continuous welding of a large part of the middle part at the connection between the box body 3 and the partition 31. For the area at the end of the partition 31 that is not covered by continuous welding, it can be repaired by using the laser welding head 11 after the horizontal bar floating fixture assembly 4 is removed, so as to ensure the integrity of the overall weld at the connection between the box body 3 and the partition 31.

[0055] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
