Technical Field

[0001] This utility model relates to the technical field of aluminum single-panel laser welding machines, specifically to an anti-deformation aluminum single-panel laser welding machine. Background Technology

[0002] Laser welding machines are welding equipment that uses high-energy laser beams to process materials. They heat materials by focusing the laser to form a molten pool, and feature a small heat-affected zone, minimal welding deformation, and a high degree of automation. They are suitable for various processes such as spot welding and lap welding of thin-walled materials and precision parts, and are applied in fields such as automobile manufacturing, electronics industry, biomedicine, and mold repair.

[0003] Currently, when laser welding machines are used to weld aluminum panels, the properties of the aluminum panels cause the welded and continuously heated areas to experience material protrusion due to the pressure from the clamping fixtures. In other words, the welded surface of the aluminum panel deforms due to excessive pressure.

[0004] In view of this, a laser welding machine for anti-deformation aluminum single-panel was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: A laser welding machine for anti-deformation aluminum single-panel includes a welding assembly, an anti-deformation welding assist mechanism mounted on the welding assembly, and two aluminum single-panels installed within the anti-deformation welding assist mechanism. The welding assembly includes a control module and a wire feeding module. The control module has two limiting grooves, and four symmetrically distributed pads are engaged at both ends of the control module. Positioning bolts are inserted into the pads and fixedly installed within the control module. The anti-deformation welding assist mechanism includes two plate seam support frames and two horizontal rails inserted into the two limiting grooves. Two load-bearing sliding plates are movably mounted on the outside of the two horizontal rails. Baffles are inserted into the inner sides of the two plate seam support frames. A horizontally positioned adjusting screw is movably mounted inside the baffles. A clamping device is movably mounted on the outside of the adjusting screw and engaged with the outside of the two plate seam support frames. The two aluminum single-panels are placed inside the two plate seam support frames and the clamping device.

[0007] In a preferred embodiment, the present invention can be further configured as follows: a motor is fixedly installed inside the control module, a deflection gear is fixedly installed on the transmission shaft inside the motor, and two symmetrically distributed clamping plates are fixedly installed outside the control module, with bidirectional screws movably installed inside the two clamping plates; A gear is fixedly installed at the bottom end of the bidirectional screw, and the gear is adapted to mesh with the deflection gear.

[0008] In a preferred embodiment, the present invention can be further configured as follows: a horizontally placed water-cooled trough plate is provided on the top of the baffle and the clip; a sealing gasket is fixedly installed on the bottom surface of the water-cooled trough plate; two symmetrically distributed water inlet pipes are fixedly installed on the bottom of the outer end of the water-cooled trough plate; and a drain pipe is fixedly installed on the water-cooled trough plate.

[0009] In a preferred embodiment, the present invention can be further configured such that: the interior of the water-cooled tank plate has three grooves, and the inner wall of the grooves has two symmetrically distributed guide holes.

[0010] In a preferred embodiment, the present invention can be further configured such that the plate seam support frame is composed of a trapezoidal support plate and an L-shaped support leg, and a pin is inserted into the end of the trapezoidal support plate facing the clamp.

[0011] In a preferred embodiment, the present invention can be further configured such that: four locking bolts are fixedly installed on the outside of the load-bearing slide plate, and pressure boosting wing plates are installed on the outside of two adjacent locking bolts.

[0012] In a preferred embodiment, the present invention can be further configured as follows: a second axle is installed at the bottom end of the load-bearing slide, a force arm is movably installed at the outer end of the second axle, a first axle is movably installed at the other end of the force arm, and a support plate is installed at the outer end of the first axle; The support plate is threaded onto the outside of the bidirectional screw.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. This utility model involves installing two symmetrically distributed plate seam support frames on the front of the welding assembly, and using adjustable screws to control the clamps to calibrate and pressurize the end faces of the two aluminum panels. As the two evenly distributed pressure-pressurizing wing plates pressurize the outer edges of the two aluminum panels in a centered manner, combined with the synchronous reinforcement of the clamps, the joint of the two aluminum panels will be in a low-pressure state after docking. When using a continuous welding gun to assist welding along the low-pressure joint of the two aluminum panels, the joint of the aluminum panels can avoid continuous heating and excessive pressure, which could lead to deformation defects.

[0014] 2. This utility model provides lateral support for the water-cooled tank plate through the baffle and the top of the clip. When the bottom surfaces of the two aluminum single plates are pressed against the upper surface of the sealing gasket, the coolant input through the water inlet pipe will circulate internally along the guide hole. Finally, the coolant will be released from the drain pipe. At this time, the bottom of the weld seam of the two aluminum single plates that are joined and welded can be continuously cooled, avoiding excessive heat rise of the weld seam and overflow.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0019] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a laser welding machine for anti-deformation aluminum single-panel welding. Example

[0020] Combination Figures 1 to 6As shown, the present invention provides a laser welding machine for anti-deformation aluminum single-panel, including a welding assembly 100, an anti-deformation welding aid mechanism 200 installed on the welding assembly 100, and two aluminum single-panels 300 installed in the anti-deformation welding aid mechanism 200. The anti-deformation welding aid mechanism 200 is used to provide effective support for the two aluminum single-panels 300 and reduce the extrusion pressure on the joint of the two aluminum single-panels 300.

[0021] The welding assembly 100 includes a control module 110 and a wire feeding module 120. The control module 110 has two limiting grooves 1102. Four symmetrically distributed pads 130 are snapped into both ends of the control module 110. Positioning bolts 1101 are inserted into the inside of the pads 130 and are fixedly installed inside the control module 110. The anti-deformation welding mechanism 200 includes two plate seam support frames 250 and two horizontal rails 210 inserted into two limiting grooves 1102. Two load-bearing sliding plates 220 are movably installed on the outside of the two horizontal rails 210. Baffles 2502 are inserted into the inside of the two plate seam support frames 250. A horizontally placed adjusting screw 260 is movably installed inside the baffles 2502. A clip 2503 that is snapped onto the outside of the two plate seam support frames 250 is movably installed on the outside of the adjusting screw 260. Two aluminum single panels 300 are placed inside the two panel seam load-bearing frames 250 and the fasteners 2503.

[0022] Two aluminum single panels 300 are placed on top of two panel joint support frames 250 beforehand, and the outer ends of the two aluminum single panels 300 are clamped and aligned with each other using clamps 2503. Next, the user uses a handheld laser welding gun to weld along the seam on the upper surface of the two aluminum single panels 300. At this time, the two aluminum single panels 300 in a low-pressure butt joint state can avoid the problem of overflow or deformation due to excessive pressure during the welding process. Example

[0023] Combination Figure 2 and Figure 3 As shown, based on Embodiment 1, a motor 150 is fixedly installed inside the control module 110, a deflection gear 1501 is fixedly installed on the transmission shaft inside the motor 150, and two symmetrically distributed clamping plates 1103 are fixedly installed outside the control module 110, with a bidirectional screw 140 movably installed inside the two clamping plates 1103. A gear 1401 is fixedly installed at the bottom end of the bidirectional screw 140, and the gear 1401 is adapted to mesh with the deflection gear 1501. The load-bearing slide plate 220 is externally fixed with four locking bolts 2301, and pressure boosting wing plates 230 are installed on the outside of two adjacent locking bolts 2301.

[0024] The bottom end of the load-bearing slide plate 220 is equipped with a second shaft 2403, the outer end of the second shaft 2403 is movably equipped with a lever arm 2402, the other end of the lever arm 2402 is movably equipped with a first shaft 2401, and the outer end of the first shaft 2401 is equipped with a support plate 240. The support plate 240 is threaded onto the outside of the double-acting screw 140.

[0025] Preferably, the two ends of the bidirectional screw 140 are mounted on the inner sides of the two clamping plates 1103 via two bearings. When the motor 150 starts and cooperates with the deflection gear 1501 to drive the transmission gear 1401 and the bidirectional screw 140, the bidirectional screw 140, which is rotating at a constant speed, will push the support plate 240 to rise and fall smoothly. The support plate 240 will pull the two lever arms 2402 to extend relative to each other. Finally, the load-bearing slide plate 220 connected to the outer end of the lever arm 2402 via the second shaft 2403 will drive the two evenly distributed pressure-boosting wing plates 230 to slide under constant pressure along the top and bottom of the aluminum single panel 300. This process can enhance the accurate calibration of the two aluminum single panels 300 and, together with the clamp 2503, press the ends of the two aluminum single panels 300 after calibration, thereby avoiding overflow and deformation of the joint of the two aluminum single panels 300 in the welding state due to high temperature welding. Example

[0026] Combination Figures 2 to 5 As shown, in the above embodiment, the plate seam support frame 250 is composed of a trapezoidal support plate and an L-shaped support leg, and a pin 2501 is inserted into one end of the trapezoidal support plate facing the clamp 2503. The top of the baffle 2502 and the clip 2503 is provided with a horizontally placed water-cooling trough plate 270. A sealing gasket 2701 is fixedly installed on the bottom surface of the water-cooling trough plate 270. Two symmetrically distributed water inlet pipes 2702 are fixedly installed at the bottom of the outer end of the water-cooling trough plate 270, and a drain pipe 2703 is fixedly installed on the water-cooling trough plate 270. The water-cooled trough plate 270 has three grooves inside, and the inner wall of the grooves has two symmetrically distributed guide holes 2704.

[0027] Preferably, the two pins 2501 secure the back baffle 2502 to the two plate seam support frames 250. As the clip 2503 extends laterally along the two plate seam support frames 250, the water-cooled trough plate 270, which is laterally supported by the baffle 2502 and the clip 2503, together with the sealing gasket 2701, can provide low-temperature protection for the bottom of the weld seam of the two aluminum single panels 300. With the help of the circulating flow of coolant, the welded part of the two aluminum single panels 300 is prevented from overheating and falling due to gravity.

[0028] The working principle and usage process of this utility model are as follows: First, insert two plate seam support frames 250 into two pre-reserved holes on the front of the control module 110. Then, use multiple positioning bolts 1101 to fix four pads 130 to both ends of the control module 110, and use the four pads 130 to press the two horizontal rails 210 that are snapped into the two limiting grooves 1102. By running the motor 150, until the motor 150 cooperates with the deflection gear 1501 to drive the gear 1401 and the bidirectional screw 140, the bidirectional screw 140, which is positioned and clamped by the two clamping plates 1103, is rotated. The support plate 240 will cooperate with the two first shafts 2401 to push the two lever arms 2402 to expand outward until the two load-bearing slide plates 220 move to the outermost end of the horizontal rail 210. Next, rotate the adjusting screw 260 forward until the threaded section of the adjusting screw 260 extends outward along the baffle 2502, and the clamp 2503 also extends outward. Then, place the two aluminum single panels to be welded on the exposed inner surfaces of the two plate seam support frames 250 and the clamp 2503, and use two sets of symmetrically distributed pressure wing plates 230 to limit and clamp the outer edges of the two aluminum single panels 300. Then, reverse the adjusting screw 260 until the clamp 2503, together with the two plate seam support frames 250, pre-clamps the two aluminum single panels 300. At the same time, run the motor 150 until the bidirectional screw 140 drives the support plate 240 to descend until the two sets of pressure-boosting wing plates 230 apply pressure to the two aluminum single panels 300 in the center and are in a state of minimum gap. Then, use a handheld welding gun to weld along the gap between the upper surfaces of the two aluminum single panels 300. Meanwhile, the coolant continuously input through the two water inlet pipes 2702 will transfer along the two outermost grooves of the water-cooled trough plate 270 and be transferred along the two guide holes 2704 towards the central groove of the water-cooled trough plate 270. At this time, the circulating coolant can continuously provide temperature control protection for the bottom of the weld seam of the two aluminum single panels 300, avoiding excessive temperature rise at the welded part of the two aluminum single panels 300 and problems such as deformation and misalignment.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
