Description

Technical Field

[0001] This invention relates to the field of aluminum plate processing technology, and in particular to an aluminum plate lug welding device. Background Technology

[0002] In industrial production, aluminum sheets are widely used in electronics, automotive, construction, aerospace, and other industries due to their lightweight, corrosion resistance, and excellent electrical and thermal conductivity. As a key structure for connecting and suspending aluminum sheet components, the welding quality of aluminum sheet lugs directly affects the stability and safety of the entire equipment or component.

[0003] This research was developed to address the problem of poor positioning of aluminum plate lugs when welding them with existing welding equipment. In the existing technology, poor positioning during the aluminum plate lug welding process leads to welding position deviation, affecting product quality and production efficiency.

[0004] Furthermore, aluminum plates usually require welding lugs to both ends or all four sides. Typically, after welding one end, the position of the aluminum plate needs to be readjusted and fixed, which wastes working time. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides an aluminum plate lug welding device that effectively solves the problem that poor positioning leads to welding position deviation, affecting product quality and production efficiency in the aluminum plate lug welding process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding device for aluminum plate lugs includes a base, a support plate fixedly mounted on the upper end of the base, a first slide plate that can elastically rebound slidably connected to the support plate, an intermittent drive structure provided on the support plate, the intermittent drive structure can intermittently drive a mounting plate corresponding to the first slide plate, a second slide plate slidably connected to the first slide plate, a positioning structure provided on the second slide plate, the positioning structure including a fixing frame fixedly mounted on the second slide plate, a sliding side block opposite the fixing frame that is slidably connected to the second slide plate and whose distance from the fixing frame can be adjusted according to the type of lug, a locking rod that can be locked on the fixing frame, a welding frame mounted on the locking rod, and a welding machine that can reciprocate along the welding frame mounted on the welding frame.

[0008] Preferably, the intermittent drive structure further includes a first motor mounted on the base. The output end of the first motor drives the active bevel gear to rotate, the active bevel gear drives the driven bevel gear to rotate, the driven bevel gear drives the rotating shaft to rotate, the rotating shaft can intermittently drive the indexing plate to rotate, the indexing plate drives the mounting plate to rotate intermittently, thereby adjusting the welding position of the aluminum plate on the mounting plate.

[0009] Preferably, the lower end of the first sliding plate is provided with a first sliding pin that is slidably connected to the inner wall of the support plate, and a fixing block is fixedly connected to one end of the support plate. A spring is provided between the fixing block and the first sliding plate to adjust the position of the mounting plate and fit the first sliding plate onto the mounting plate.

[0010] Preferably, a second sliding pin is installed at the lower end of the sliding block and is slidably connected to the inner wall of the second sliding plate. Bolts are installed in the sliding block and the fixing frame, and the bolts can slide along the inner wall of the sliding block and the fixing frame. A nut is provided at one end of the bolt.

[0011] Preferably, a first hydraulic cylinder is provided at the upper end of the second slide plate, and a slide cylinder frame that is slidably connected to the bolt is installed at the output end of the first hydraulic cylinder. A push plate corresponding to the hanging lug is installed at one end of the slide cylinder frame.

[0012] Preferably, the clamping rod is rotatably connected to one end of the fixing frame, the clamping rod is provided with a rotating column rotatably connected to the fixing frame, a worm gear is fixedly connected to one end of the rotating column, and a worm gear meshing with the worm gear is rotatably connected to one end of the fixing frame.

[0013] Preferably, a second hydraulic cylinder is installed at the upper end of the welding frame, and the output end of the second hydraulic cylinder is provided with a mounting slider that is slidably connected to the inner wall of the welding frame. The welding machine is mounted on the mounting slider.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] By rotating the mounting plate, the next position to be welded on the aluminum plate is rotated to the position corresponding to the first slide plate. The above welding process is repeated until all the welding work of the lugs on the aluminum plate is completed. This effectively solves the problem that in the process of welding the lugs on the aluminum plate, it is usually necessary to weld one end and then readjust and fix the position of the aluminum plate, which wastes working time and effectively improves work efficiency.

[0016] The distance between the sliding block and the fixed frame in the positioning structure is adjusted. Since the sliding block is slidably connected to the second sliding plate, it can be adjusted to a position that matches the size of the hanging ear, ensuring that the hanging ear can be stably clamped. Then, the aluminum plate is placed on the mounting plate so that the part of the hanging ear to be welded corresponds to the clamping area of ​​the fixed frame and the sliding block. This effectively solves the problem of poor positioning during the welding process of aluminum plate hanging ears, which leads to welding position deviation and affects product quality and production efficiency.

[0026] like Figure 1-8 As shown, an aluminum plate lug welding device includes a base 1, a support plate 2 fixedly installed on the upper end of the base 1, a first slide plate 5 that can elastically rebound slidably connected to the support plate 2, an intermittent drive structure provided on the support plate 2, the intermittent drive structure can intermittently drive the mounting plate 8 corresponding to the first slide plate 5, a second slide plate 6 slidably connected to the first slide plate 5, a positioning structure provided on the second slide plate 6, the positioning structure including a fixing frame 19 fixedly installed on the second slide plate 6, a sliding side block 15 opposite the fixing frame 19 that is slidably connected to the second slide plate 6 and whose distance from the fixing frame 19 can be adjusted according to the type of lug 23, a locking rod 27 is lockably installed on the fixing frame 19, a welding frame 31 is installed on the locking rod 27, and a welding machine 30 that can reciprocate along the welding frame 31 is installed on the welding frame 31.

[0027] In use, the operator adjusts the distance between the sliding block 15 and the fixing frame 19 in the positioning structure according to the type of the hanging ear 23 to be welded. Since the sliding block 15 is slidably connected to the second sliding plate 6, it can be adjusted to a position that matches the size of the hanging ear 23, ensuring that the hanging ear 23 can be stably clamped. Then, the aluminum plate 9 is placed on the mounting plate 8, so that the part of the hanging ear 23 to be welded corresponds to the clamping area of ​​the fixing frame 19 and the sliding block 15. Next, the position of the clamping rod 27 on the fixing frame 19 is adjusted so that it can be tightly clamped onto the aluminum plate 9. Then, the clamping rod 27 is locked to complete the initial positioning. At the same time, according to the welding requirements, the initial positioning of the welding machine 30 on the welding frame 31 is adjusted. The initial position prepares for subsequent welding. Entering the welding operation stage, the welding machine 30 can reciprocate along the welding frame 31 to weld the aluminum plate 9 and the lug 23. After welding at one end, the fixing of the clamping rod 27 is released, and the intermittent rotating structure is controlled to work, intermittently driving the mounting plate 8 to rotate a quarter circumference. When the mounting plate 8 drives the aluminum plate 9 to the welding position corresponding to the first sliding plate 5, the intermittent rotating structure stops, and the mounting plate 8 remains stationary. At this time, the first sliding plate 5 slides towards the mounting plate 8 under the action of elastic rebound, driving the second sliding plate 6 and the positioning structure to approach the aluminum plate 9 as a whole, so that the welding part of the lug 23 is precisely aligned with the working end of the welding machine 30.

[0028] Next, the second slide plate 6 slides on the first slide plate 5 to further fine-tune the position of the positioning structure, ensuring that the welding point between the lug 23 and the aluminum plate 9 is in the optimal welding position. After that, the welding machine 30 begins to reciprocate along the welding frame 31 to perform welding operations on the connection between the lug 23 and the aluminum plate 9. During the welding process, the clamping rod 27 continuously applies pressure to the aluminum plate 9 and the lug 23 to prevent the welding quality from being affected by high temperature deformation or positional displacement.

[0029] Once a welding point is completed, the welding machine 30 returns to its initial position. The first slide plate 5 resets under the action of elastic force, driving the second slide plate 6 and the positioning structure away from the mounting plate 8. Subsequently, the intermittent drive structure drives the mounting plate 8 again, rotating the next welding position of the aluminum plate 9 to the position corresponding to the first slide plate 5. The above welding process is repeated until all the welding work of the lugs 23 on the aluminum plate 9 is completed. This effectively solves the problem of poor positioning during the welding process of the lugs 23 on the aluminum plate 9, which leads to welding position deviation and affects product quality and production efficiency. Moreover, since the aluminum plate 9 usually needs to have lugs 23 on both ends or all four sides, there is no need to flip the aluminum plate 9 and re-fix and reposition it, which effectively improves work efficiency.

[0030] The intermittent drive structure also includes a first motor 10 mounted on the base 1. The output end of the first motor 10 drives the active bevel gear 11 to rotate, the active bevel gear 11 drives the driven bevel gear 12 to rotate, the driven bevel gear 12 drives the rotating shaft 13 to rotate, the rotating shaft 13 can intermittently drive the indexing plate 14 to rotate, the indexing plate 14 drives the mounting plate 8 to rotate intermittently, thereby adjusting the welding position of the aluminum plate 9 on the mounting plate 8.

[0031] like Figure 3 As shown, after the first motor 10 starts, its output end drives the active bevel gear 11 to rotate. The active bevel gear 11 meshes with the driven bevel gear 12, thereby driving the driven bevel gear 12 to rotate synchronously. The driven bevel gear 12 then drives the rotating shaft 13 connected to it to rotate. During the rotation, the rotating shaft 13 intermittently drives the indexing plate 14 to rotate. The indexing plate 14 is connected to the mounting plate 8, thereby driving the mounting plate 8 to rotate intermittently. When the mounting plate 8 drives the aluminum plate 9 to the welding position corresponding to the first slide plate 5, the rotating shaft 13 stops driving the indexing plate 14 to rotate, the intermittent drive structure stops operating, and the mounting plate 8 remains stationary. At this time, the first slide plate 5 slides towards the mounting plate 8 under the action of elastic rebound, driving the hanging lug 23 on the second slide plate 6 to approach the aluminum plate 9, so that the welding part of the hanging lug 23 is precisely connected with the working end of the welding machine 30.

[0032] The lower end of the first sliding plate 5 is provided with a first sliding pin 7 that is slidably connected to the inner wall of the support plate 2. One end of the support plate 2 is fixedly connected with a fixing block 3. A spring 4 is provided between the fixing block 3 and the first sliding plate 5 to adjust the position of the mounting plate 8 so that the first sliding plate 5 fits onto the mounting plate 8.

[0033] like Figure 4 As shown, the first sliding pin 7 at the lower end of the first sliding plate 5 slides on the inner wall of the support plate 2. Since a spring 4 is provided between the fixing block 3 and the first sliding plate 5, under the elastic force of the spring 4, the first sliding plate 5 slides towards the mounting plate 8, driving the second sliding plate 6 to approach the aluminum plate 9 as a whole, so that the welding part of the hanging ear 23 is precisely connected with the working end of the welding machine 30 and can be tightly attached to the mounting plate 8.

[0034] The lower end of the sliding block 15 is equipped with a second sliding pin 16 that is slidably connected to the inner wall of the second slide plate 6. Bolts 18 are installed in the sliding block 15 and the fixing frame 19, and the bolts 18 can slide along the inner wall of the sliding block 15 and the fixing frame 19. A nut 17 is provided at one end of the bolt 18.

[0035] like Figure 5As shown, the sliding block 15 can slide stably on the second slide plate 6 via the second sliding pin 16. At the same time, bolts 18 are installed in the sliding block 15 and the fixing frame 19. The operator can loosen the nut 17 to move the sliding block 15, adjust it to a position that matches the size of the hanging ear 23, and then tighten the nut 17 to lock the bolt 18, thereby fixing the sliding block 15 and ensuring that the hanging ear 23 can be stably clamped.

[0036] The upper end of the second slide plate 6 is provided with a first hydraulic cylinder 20. The output end of the first hydraulic cylinder 20 is equipped with a slide cylinder frame 21 that is slidably connected to the bolt 18. One end of the slide cylinder frame 21 is equipped with a push plate 22 corresponding to the hanging lug 23.

[0037] like Figure 5 As shown, the first hydraulic cylinder 20 at the upper end of the second slide plate 6 is activated. The output end of the first hydraulic cylinder 20 pushes the slide frame 21 to move. Since the slide frame 21 is slidably connected to the bolt 18, the slide frame 21 can push the bolt 18 to slide stably, thereby driving the push plate 22 installed at one end to move towards the hanging ear 23 until the push plate 22 and the hanging ear 23 are in close contact, further positioning and fixing the hanging ear 23 to prevent the hanging ear 23 from shifting during welding.

[0038] The fixing frame 19 is rotatably connected to the clamping rod 27 at one end. The clamping rod 27 is provided with a rotating column 32 that is rotatably connected to the fixing frame 19. A worm gear 25 is fixedly connected to one end of the rotating column 32. A worm 24 that meshes with the worm gear 25 is rotatably connected to one end of the fixing frame 19.

[0039] like Figure 6 and 8 As shown, a handle 26 is provided at one end of the worm 24. The handle 26 drives the worm 24 to rotate, which in turn drives the worm wheel 25 to rotate. The worm wheel 25 drives the clamping rod 27 to deflect and clamp onto the aluminum plate 9, thereby fixing the position of the aluminum plate 9.

[0040] The upper end of the welding frame 31 is equipped with a second hydraulic cylinder 28, and the output end of the second hydraulic cylinder 28 is provided with an installation slider 29 that is slidably connected to the inner wall of the welding frame 31. The welding machine 30 is mounted on the installation slider 29.

[0041] like Figure 6 and 7 As shown, the second hydraulic cylinder 28 can drive the mounting slider 29 to slide along the welding frame 31. The mounting slider 29 drives the welding machine 30 to move back and forth to weld the joint between the aluminum plate 9 and the hanging ear 23.

[0042] The working process of this invention is as follows: When using this invention, the operator, according to the type of the lug 23 to be welded, allows the sliding block 15 to slide stably on the second slide plate 6 via the second sliding pin 16. Simultaneously, bolts 18 are installed inside the sliding block 15 and the fixing frame 19. The operator can loosen the nut 17 to move the sliding block 15. After adjusting it to a position suitable for the size of the lug 23, the operator activates the first hydraulic cylinder 20 at the upper end of the second slide plate 6. The output end of the first hydraulic cylinder 20 pushes the slide frame 21 to move. Because the slide frame 21 is slidably connected to the bolt 18, the slide frame 21 can push the bolt 18 to slide stably, thereby driving the push plate 2 installed at one end. 2. Move towards the hanging ear 23 until the push plate 22 is in close contact with the hanging ear 23 to further position and fix the hanging ear 23 to prevent displacement of the hanging ear 23 during welding. Tighten the nut 17 to lock the bolt 18, and then fix the sliding block 15 to ensure that the hanging ear 23 can be stably clamped. Then, place the aluminum plate 9 on the mounting plate 8 so that the part of the hanging ear 23 to be welded corresponds to the clamping area of ​​the fixing frame 19 and the sliding block 15. Next, drive the worm 24 to rotate through the handle 26. The worm 24 drives the worm wheel 25 to rotate. The worm wheel 25 drives the clamping rod 27 to deflect so that it can be tightly clamped on the aluminum plate 9, completing the initial positioning.

[0043] Meanwhile, according to the welding requirements, the initial position of the welding machine 30 on the welding frame 31 is adjusted to prepare for subsequent welding. The second hydraulic cylinder 28 can drive the mounting slider 29 to slide along the welding frame 31. The mounting slider 29 drives the welding machine 30 to move back and forth to weld the joint between the aluminum plate 9 and the hanging ear 23. After one end is welded, the fixing of the buckle rod 27 is released.

[0044] After the first motor 10 starts, its output end drives the active bevel gear 11 to rotate. The active bevel gear 11 meshes with the driven bevel gear 12, thereby driving the driven bevel gear 12 to rotate synchronously. The driven bevel gear 12 then drives the rotating shaft 13 connected to it to rotate. During the rotation, the rotating shaft 13 intermittently drives the indexing plate 14 to rotate. The indexing plate 14 is connected to the mounting plate 8, thereby driving the mounting plate 8 to rotate intermittently. When the mounting plate 8 drives the aluminum plate 9 to the welding position corresponding to the first slide plate 5, the rotating shaft 13 stops driving the indexing plate 14 to rotate, and the mounting plate 8 remains stationary. At this time, the first slide plate 5 slides towards the mounting plate 8 under the action of elastic rebound, driving the lug 23 on the second slide plate 6 to approach the aluminum plate 9, so that the welding part of the lug 23 is precisely connected with the working end of the welding machine 30.

[0045] The second slide plate 6 slides on the first slide plate 5 to ensure that the welding point between the lug 23 and the aluminum plate 9 is in the optimal welding position. Then, the welding machine 30 starts to reciprocate along the welding frame 31 to perform welding operations on the connection between the lug 23 and the aluminum plate 9. During the welding process, the clamping rod 27 continuously applies pressure to the aluminum plate 9 and the lug 23 to prevent the welding quality from being affected by high temperature deformation or positional displacement.

[0046] Once a welding point is completed, the welding machine 30 returns to its initial position and drives the mounting plate 8 again to rotate the next welding position of the aluminum plate 9 to the station corresponding to the first sliding plate 5. The above welding process is repeated until all the welding work of the lugs 23 on the aluminum plate 9 is completed. This effectively solves the problem of poor positioning during the welding process of the lugs 23 on the aluminum plate 9, which leads to welding position deviation and affects product quality and production efficiency. Moreover, since the aluminum plate 9 usually needs to have lugs 23 on both ends or all four sides, there is no need to flip the aluminum plate 9 and re-fix and reposition it, which effectively improves work efficiency.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may 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.
