[0004] In the aforementioned patent, the clamping device can effectively and accurately limit and fix the welded workpiece from the inside out and from top to bottom, improving processing efficiency and processing accuracy. However, there are still problems. Basically, all welded parts need to be welded on both sides, so no matter how the clamping is done, it is necessary to adjust the clamping twice, which wastes a lot of time. Moreover, the above-mentioned clamping requires a lot of time to adjust and accurately clamp the workpiece. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser welding clamping device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser welding clamping device, used to prevent excessive clamping force when clamping thin parts, comprising a preventive device, the preventive device further comprising;

[0007] A frame for supporting the device, wherein a placement slot is provided on the top of the frame;

[0008] A telescopic device is provided on the top of the frame and is used to provide clamping force to the workpiece.

[0009] A welding device, which is fixedly mounted on the top of the frame, is used to weld workpieces;

[0010] The elastic telescopic plate has its fixed end fixedly installed at the output end of the telescopic device, and its free end rotatably mounted with gear A. A rotating plate is fixedly installed on the side of gear A away from the elastic telescopic plate. The rotating plate is used to flip the workpiece. When the elastic telescopic plate moves, it drives gear A to move. When gear A moves, it drives the rotating plate to move. When the rotating plate moves, it drives the push rod to move.

[0011] According to the above technical solution, the prevention device further includes a cover plate, a double-free intermediate fixing component, an elastic telescopic block, a push rod, a telescopic block, and a rack. The cover plate is slidably installed on the top of the frame. The fixed end of the double-free intermediate fixing component is fixedly installed on the top of the cover plate. The elastic telescopic block is fixedly installed on the free end of the double-free intermediate fixing component. The push rod is rotatably installed on the end of the rotating plate near the elastic telescopic block. The fixed end of the telescopic block is fixedly installed on the top of the welding device. The rack is fixedly installed on the free end of the telescopic block. When the push rod moves, it will contact the double-free intermediate fixing component. When the push rod contacts the double-free intermediate fixing component, it will move the push rod towards the weldment.

[0012] According to the above technical solution, the rack meshes with gear A, a spring is provided between the push rod and the rotating plate, the double-free intermediate fixing member contacts the push rod, a push groove is provided on the side of the rack near the inner wall of the frame, and the tooth block on gear A is rotatably connected to gear A.

[0013] The machine frame is equipped with a cleaning device for simple slag removal from the newly welded workpiece and a sorting device for sorting the welded parts. When the rotating plate rotates, it will cause the welded parts to rotate and flip. At the same time, since the tooth block on gear A is rotatably connected to gear A, gear A will not rotate when the rack descends.

[0014] According to the above technical solution, the cleaning device includes a B gear, a rotating rod, a C gear, a round rod, a sliding rod, and a brush plate. The B gear is rotatably mounted on the inner wall of the placement slot of the frame. The rotating rod is rotatably mounted on the inner wall of the placement slot of the frame. A sliding groove is formed on the inner wall of the placement slot of the frame, and a slider is slidably mounted on the sliding groove. The C gear is rotatably mounted on the side of the slider away from the sliding groove. The round rod is fixedly mounted on the side of the C gear away from the rack. A spiral groove is formed on the circumference of the round rod. The sliding rod is slidably mounted on the spiral groove of the round rod. The brush plate is fixedly mounted on the top of the sliding rod. The sliding rod is connected to the inner wall of the placement slot of the frame. When the rotating rod rotates, it lifts the slider inside the sliding groove upward, and the rotating rod contacts the rack. When the slider moves, it drives the C gear to move. When the C gear moves, it meshes with the B gear.

[0015] According to the above technical solution, the cleaning device also includes a steel rod and a screen rod. The steel rod is fixedly installed at the bottom of the sliding rod, and the screen rod is fixedly installed on the inner wall of the frame. When the welded part is on the screen rod, it slides to the bottom. When the sliding rod moves, it will drive the steel rod to move. When the steel rod moves, it will clean the gaps between the screen rods.

[0016] According to the above technical solution, the rack meshes with gear B, gear B meshes with gear C, the rotating rod contacts the rack, and the rotating rod contacts the slider. When the brush plate moves, it cleans the welded parts on it. When the welded parts rotate, the rack moves upward, so gear C is at the lowest point and will not affect the flipping of the welded parts.

[0017] According to the above technical solution, the sorting device includes a pressure rod, an inclined block, an elastic telescopic push column, a slide rail, a collection basket, a stop bar, and a spare basket. The pressure rod is fixedly installed at the bottom of the steel rod. The inclined block slides through the inner wall of the placement slot of the frame. The fixed end of the elastic telescopic push column is fixedly installed on the front of the frame, and the free end of the elastic telescopic push column is fixedly connected to the inclined block. The slide rail is fixedly installed on the front of the frame. The collection basket is slidably installed on the slide rail. The stop bar is fixedly installed inside the collection basket. The spare basket is slidably installed on the top of the collection basket. When the pressure rod contacts the inclined block, the pressure rod will squeeze the inclined block. When the inclined block is squeezed, it will move away from the frame. When the inclined block moves, it will squeeze the elastic telescopic push column.

[0018] According to the above technical solution, the pressure rod is in contact with the inclined block, and the collection basket is in contact with the spare basket. When the welded part falls into the inside of the collection basket, the elastic telescopic push column will move the welded part towards the collection basket. When the welded part moves into the inside of the collection basket, it will contact the baffle inside the collection basket.

[0019] This invention provides a laser welding clamping device. It has the following advantages:

[0020] (1) In this invention, after the push rod contacts the double free intermediate fixing part, it will move towards the direction of the welded part, thereby pushing the two welded parts to automatically align, reducing human operation error, ensuring the positional accuracy of the welded parts before welding, and when clamping thin workpieces, the elastic telescopic plate can absorb part of the clamping force through its own elastic deformation, avoiding deformation, indentation or damage to thin workpieces due to excessive driving force of the telescopic device, thus ensuring the structural integrity of thin workpieces during the clamping process.

[0021] (2) The invention uses a transmission structure such as a rack, B gear, and C gear to drive the brush plate to move and clean the surface of the welded parts before welding. This can remove impurities, dust or oxide layers on the welded parts, avoid impurities from affecting the weld strength or causing welding defects, thereby improving welding accuracy and finished product quality. When the sliding rod moves, it drives the steel rod to move synchronously and cleans the gap between the screen rods, avoiding debris and impurities generated during the welding process from getting stuck in the gap between the screen rods, preventing problems such as jamming and accumulation when the subsequent workpieces slide down, ensuring the smoothness of the workpieces conveyed through the screen rods after welding, and reducing equipment failure and manual cleaning costs.

[0022] (3) In this invention, after the welded parts fall into the collection basket, the push force of the elastic telescopic push column and the guiding action of the stop bar can make the welded parts lean against the inner wall of the collection basket away from the machine frame, avoiding jamming or damage caused by disorderly accumulation. When the collection basket is full, it will be completely pushed out to the bottom of the spare basket. At this time, the spare basket will automatically fall onto the slide rail to receive the new welded parts. There is no need for frequent manual replacement of the collection container, avoiding production interruption caused by machine stoppage and basket replacement. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] Please see Figures 1-8 One embodiment of the present invention is: a laser welding clamping device, used to prevent excessive clamping force when clamping thin parts, including a preventive device, the preventive device further comprising;

[0034] The frame 1 is used to support the device, and a placement slot is provided on the top of the frame 1;

[0035] Telescopic device 2 is installed on the top of frame 1 and is used to provide clamping force for the workpiece.

[0036] Welding device 4 is fixedly installed on the top of frame 1 and is used to weld workpieces.

[0037] The elastic telescopic plate 304 has its fixed end fixedly installed at the output end of the telescopic device 2. The free end of the elastic telescopic plate 304 is rotatably mounted with gear A 305. A rotating plate 306 is fixedly installed on the side of gear A 305 away from the elastic telescopic plate 304. The rotating plate 306 is used to flip the workpiece. The elastic telescopic plate 304 can absorb part of the clamping force through its own elastic deformation, avoiding deformation, indentation or damage to the thin workpiece due to excessive driving force of the telescopic device 2, thus ensuring the structural integrity of the thin workpiece during the clamping process.

[0038] The preventive device also includes a cover plate 301, a double-free intermediate fixing member 302, an elastic telescopic block 303, a push rod 307, a telescopic block 308, and a rack 309. The cover plate 301 is slidably mounted on the top of the frame 1. The fixed end of the double-free intermediate fixing member 302 is fixedly mounted on the top of the cover plate 301. The elastic telescopic block 303 is fixedly mounted on the free end of the double-free intermediate fixing member 302. The push rod 307 is rotatably mounted on one end of the rotating plate 306 near the elastic telescopic block 303. The fixed end of the telescopic block 308 is fixedly mounted on the top of the welding device 4. The rack 309 is fixedly mounted on the free end of the telescopic block 308. When the push rod 307 moves, it will contact the double-free intermediate fixing member 302. When the push rod 307 contacts the double-free intermediate fixing member 302, it will move the push rod 307 towards the weldment.

[0039] The rack 309 meshes with the A gear 305. A spring is provided between the push rod 307 and the rotating plate 306. The double-free intermediate fixing part 302 contacts the push rod 307. A push groove is provided on the side of the rack 309 near the inner wall of the frame 1. The tooth block on the A gear 305 is rotatably connected to the A gear 305. When the rotating plate 306 rotates, it will drive the welded parts to rotate and flip. At the same time, since the tooth block on the A gear 305 is rotatably connected to the A gear 305, the A gear 305 will not rotate when the rack 309 descends.

[0040] In this embodiment, during operation: the cover plate 301 is slid into the top of the placement slot at the top of the frame 1, the welded part is placed on top of the cover plate 301, and the double free intermediate fixing member 302 is adjusted according to the workpiece on the cover plate 301. If the width of the workpiece is small, the elastic telescopic block 303 is pulled out to release the restriction on the free end of the double free intermediate fixing member 302. After the restriction on the free end of the double free intermediate fixing member 302 is released, the free end of the double free intermediate fixing member 302 is pulled outward. When the double free intermediate fixing member 302 is pulled to the appropriate position, the elastic telescopic block 303 is engaged. The double-free intermediate fixing member 302 is inserted into the slot, limiting the double-free intermediate fixing member 302. The telescopic device 2 is then activated. When the telescopic device 2 is activated, the elastic telescopic plate 304 moves towards the welded part. As the elastic telescopic plate 304 moves, it compresses the internal welded part. When the welded part at the top of the cover plate 301 is relatively thin, the elastic telescopic plate 304 cushions the welded part, preventing excessive pressure from the telescopic device 2 from damaging it. When the elastic telescopic plate 304 moves, it drives gear A 305 to move. When gear 305 moves, it drives rotating plate 306 to move. When rotating plate 306 moves, it drives push rod 307 to move. When push rod 307 moves, it contacts the double-free intermediate fixing member 302. When push rod 307 contacts the double-free intermediate fixing member 302, it moves closer to the welded parts. As rotating plate 306 continues to move, push rod 307 continues to move closer to the welded parts, aligning the two welded parts. Once the welded parts are aligned, cover plate 301 is pulled outwards to initiate the operation. When the welding device 4 is activated and moves downward, it will drive the telescopic block 308 to move downward. When the telescopic block 308 moves, it will drive the rack 309 to move. When the rack 309 moves, it will drive the A gear 305 to rotate. When the A gear 305 rotates, it will drive the rotating plate 306 to rotate. When the rotating plate 306 rotates, it will drive the welded part to rotate and flip. At the same time, since the tooth block on the A gear 305 is rotatably connected to the A gear 305, the A gear 305 will not rotate when the rack 309 descends.

[0041] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the frame 1 is internally provided with a cleaning device for simple slag removal of freshly welded workpieces and a tidying device for tidying up the welded parts. The cleaning device includes a B gear 501, a rotating rod 502, a C gear 503, a round rod 504, a sliding rod 505, and a brush plate 506. The B gear 501 is rotatably mounted on the inner wall of the placement slot of the frame 1, the rotating rod 502 is rotatably mounted on the inner wall of the placement slot of the frame 1, a sliding groove is provided on the inner wall of the placement slot of the frame 1, and a slider is slidably mounted on the sliding groove. The C gear 503 rotates... The sliding rod 505 is mounted on the side of the slider away from the slide groove, and the round rod 504 is fixedly mounted on the side of the C gear 503 away from the rack 309. A spiral groove is opened on the circumferential surface of the round rod 504. The sliding rod 505 is slidably mounted on the spiral groove of the round rod 504. The brush plate 506 is fixedly mounted on the top of the sliding rod 505. The sliding rod 505 is connected to the inner wall of the placement groove of the frame 1 to avoid the debris and impurities generated during the welding process from getting stuck in the gap of the screen rod 508, and to prevent problems such as jamming and accumulation when the subsequent workpieces slide down. This ensures the smooth conveying of the welded workpieces through the screen rod 508 and reduces equipment failure and manual cleaning costs.

[0042] The cleaning device also includes a steel rod 507 and a screen rod 508. The steel rod 507 is fixedly installed at the bottom of the sliding rod 505, and the screen rod 508 is fixedly installed on the inner wall of the frame 1. When the welded part is on the screen rod 508, it slides to the bottom. When the sliding rod 505 moves, it will drive the steel rod 507 to move. When the steel rod 507 moves, it will clean the gaps between the screen rods 508.

[0043] Rack 309 meshes with gear B 501, gear B 501 meshes with gear C 503, rotating rod 502 contacts rack 309, and rotating rod 502 contacts slider. When brush plate 506 moves, it cleans the welded parts on it. When the welded parts rotate, rack 309 moves upward, so gear C 503 is at the lowest point and will not affect the flipping of the welded parts.

[0044] The sorting device includes a pressure rod 601, an inclined block 602, an elastic telescopic push column 603, a slide rail 604, a collection basket 605, a stop bar 606, and a spare basket 607. The pressure rod 601 is fixedly installed at the bottom of the steel rod 507. The inclined block 602 slides through the inner wall of the placement slot of the frame 1. The fixed end of the elastic telescopic push column 603 is fixedly installed on the front of the frame 1, and the free end of the elastic telescopic push column 603 is fixedly connected to the inclined block 602. The slide rail 604 is fixedly installed on the front of the frame 1. The collection basket 605 is slidably installed on the slide rail 604. The stop bar 606 is fixedly installed inside the collection basket 605. The spare basket 607 is slidably installed on the top of the collection basket 605. At this time, the spare basket 607 automatically falls onto the slide rail 604 to receive new welded parts, eliminating the need for frequent manual replacement of collection containers and avoiding production interruptions caused by machine downtime for basket replacement.

[0045] The pressure bar 601 contacts the inclined block 602, and the collection basket 605 contacts the spare basket 607. When the welded part falls into the inside of the collection basket 605, the elastic telescopic pusher 603 will move the welded part towards the collection basket 605. When the welded part moves into the inside of the collection basket 605, it will contact the stop bar 606 inside the collection basket 605.

[0046] In this embodiment, during operation: when the rack 309 moves, it first drives the B gear 501 to rotate. As the rack 309 continues to move, it causes the push groove to contact the rotating rod 502. After the push groove contacts the rotating rod 502, it drives the rotating rod 502 to rotate. When the rotating rod 502 rotates, it lifts the slider inside the slide groove upwards. The rotating rod 502 then contacts the rack 309. When the slider moves, it drives the C gear 503 to move. When the C gear 503 moves, it meshes with the B gear 501. After the B gear 501 meshes with the C gear 503, it drives the C gear 503 to rotate. When the C gear 503 rotates, it drives the round rod 504 to rotate. When the round rod 504 rotates, it drives the sliding rod 505 to advance. The sliding rod 505 moves, which drives the brush plate 506 to move. When the brush plate 506 moves, it cleans the welded parts. When the welded parts rotate, the rack 309 moves upward, so the C gear 503 is at the lowest point and will not affect the rotation of the welded parts. After the welded parts are cleaned and welded, the operator closes the telescopic device 2. When the telescopic device 2 is closed, the welded parts will fall into the placement groove. When the welded parts fall into the placement groove, they will fall onto the screen rod 508. When the welded parts are on the screen rod 508, they will slide to the bottom. When the sliding rod 505 moves, it drives the steel rod 507 to move. When the steel rod 507 moves, it cleans the gaps between the screen rods 508.

[0047] When the steel rod 507 moves, it drives the pressure rod 601 to move as well. When the pressure rod 601 moves, it comes into contact with the inclined block 602. When the pressure rod 601 contacts the inclined block 602, it exerts pressure on the inclined block 602. When the inclined block 602 is pressured, it moves away from the frame 1. When the inclined block 602 moves, it pressures the elastic telescopic push column 603. When the elastic telescopic push column 603 is pressured, it moves towards the collection basket 605. When the welded part falls into the collection basket 605, the elastic telescopic push column 603 will... The welding piece moves towards the collection basket 605. When the welding piece moves into the collection basket 605, it will contact the baffle 606 inside the collection basket 605. When the welding piece contacts the baffle 606, it will lean against the inner wall of the collection basket 605 on the side away from the frame 1. When the second welding piece moves, it will push the collection basket 605 on the slide rail 604. When the inside of the collection basket 605 is full, it will push the collection basket 605 completely out of the bottom of the spare basket 607. When the collection basket 605 is pushed out, the spare basket 607 will fall onto the slide rail 604 for the next receiving.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
