Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly to an automatic welding device for correcting aluminum plates. Background Art

[0002] Aluminum plate is a type of aluminum material, which refers to plate-shaped aluminum products finally manufactured through processes such as rolling, extrusion, stretching, and forging of aluminum billets by plastic processing methods. During the processing of aluminum plates, when two aluminum plates need to be welded into one plate, a welding device is usually used. However, the traditional welding method has the following disadvantages:

[0003] 1. It is not only time-consuming but also prone to errors for workers to perform positioning and calibration. Especially for welding operations requiring high precision, due to the lack of an accurate positioning system, traditional welding devices may result in poor welding consistency, thereby affecting the overall quality of the product.

[0004] 2. The manual operation process is slow and is easily affected by the skill level of the operator, which makes it difficult to achieve high production efficiency. In addition, manual operation may also increase safety risks because the operator needs to directly contact the machine. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks, the technical problem to be solved is: to provide an automatic welding device for correcting aluminum plates.

[0006] Technical Solution: An automatic welding device for correcting aluminum plates, comprising a workbench, a support frame, an electric slide rail, a welding machine, and a controller.

Hinged rods are rotatably connected to the positions near the front and rear ends of the pushing blocks on both sides of the top of the workbench. First torsion springs are connected between the hinged rods and the workbench. The other ends of the hinged rods are slidably and rotatably connected to the sliding blocks.

[0009] Further, it further includes a fixing frame, a small motor, a rotating block, a connecting block, a pushing block, a second torsion spring and a compression spring. Fixing frames are symmetrically connected to the rear side of the top of the workbench. Small motors are installed on the upper sides of the fixing frames.

[0013] Further, it further includes cleaning brushes. Cleaning brushes for cleaning the welding joints of the aluminum plates are connected to both side walls of the reference block.

[0014] Compared with the prior art, the present invention has the following advantages: 1.

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment: An automatic welding device for correcting aluminum plates, as Figures 1-7 shown, includes a workbench 1, a support frame 101, an electric slide rail 102, a welding machine 103, a controller 104, a reference block 201, a sliding block 301, a correction block 302, a buffer spring 303 and a power assembly. A controller 104 is installed on the front side of the workbench 1. The rear side of the top of the workbench 1 is connected to the support frame 101 by bolts. An electric slide rail 102 is installed on the upper side of the support frame 101. A welding machine 103 is slidably connected to the electric slide rail 102. A reference block 201 for adjusting the placement angle of the aluminum plate is slidably connected to the middle of the top of the workbench 1. Sliding blocks 301 are slidably connected to the front and rear symmetry on both the left and right sides of the top of the workbench 1. Correction blocks 302 for centering and correcting the aluminum plate are slidably connected to the sliding blocks 301. Two buffer springs 303 are connected between the correction blocks 302 and the sliding blocks 301 on the same side. A power assembly is provided on the workbench 1. The electric slide rail 102 and the welding machine 103 are both electrically connected to the controller 104.

[0032] As Figures 3-7 shown, the power assembly includes a driving motor 202, a screw rod 203, a moving block 204 and a transmission assembly. A driving motor 202 is installed in the middle of the bottom of the workbench 1. The driving motor 202 is electrically connected to the controller 104. A screw rod 203 is connected to the output shaft of the driving motor 202. A moving block 204 is threadedly connected to the screw rod 203. The moving block 204 is connected to the reference block 201. A transmission assembly is provided on the reference block 201.

[0033] As Figures 4-7As shown, the transmission assembly includes a hinged rod 401, a first torsion spring 402, a transmission plate 403, and a pushing block 404. Transmission plates 403 are rotatably connected to the left and right sides of the bottom of the reference block 201. Pushing blocks 404 are symmetrically and slidably connected to the left and right on the workbench 1. The pushing block 404 is rotatably connected to the outer side of the transmission plate 403 on the same side. Hinged rods 401 are rotatably connected to the positions near the front and rear ends of the pushing block 404 on the left and right sides of the top of the workbench 1. First torsion springs 402 are connected between the hinged rods 401 and the workbench 1. The other ends of the hinged rods 401 are slidably and rotatably connected to the sliding blocks 301.

[0034] Place two aluminum plates on the left and right sides of the top of the workbench 1 respectively, with the inner sides of the aluminum plates against the reference block 201 to ensure the accuracy of the placement angle of the aluminum plates. After placement, operate the controller 104 to start the drive motor 202. The output shaft of the drive motor 202 rotates to drive the screw 203 to rotate. The screw 203 drives the moving block 204 and the reference block 201 to move downward until the height of the reference block 201 is the same as that of the workbench 1. During the downward movement of the reference block 201, it drives the transmission plate 403 to rotate, and the transmission plate 403 pushes the pushing block 404 to move inward. In the initial state, the pushing block 404 abuts against the hinge rod 401, and the first torsion spring 402 is in a deformed state. When the pushing block 404 moves inward and no longer abuts against the hinge rod 401, the first torsion spring 402 will rebound and reset, thereby driving the hinge rod 401 to rotate. The hinge rod 401 then pushes the sliding block 301 and the correction block 302 to move inward. The correction block 302 will contact the front and rear sides of the aluminum plate to center and correct the aluminum plate. The buffer spring 303 plays a buffering role to prevent the correction block 302 from pressing the aluminum plate too tightly and can be applicable to aluminum plates of different lengths. After the aluminum plates are centered, the two aluminum plates can be pushed inward to the top surface of the reference block 201 by tools so that the two aluminum plates are in contact with each other. The welded edges in contact are aligned with the welding machine 103. Subsequently, the controller 104 can be operated to start the welding machine 103 and the electric slide rail 102, and the two work in cooperation. The electric slide rail 102 drives the welding machine 103 to move forward intermittently, and the welding machine 103 will automatically extend and shorten to weld the two aluminum plates, realizing an automated welding process. After the welds of the two aluminum plates are welded, the controller 104 can be operated to turn off the welding machine 103 and control the electric slide rail 102 to drive the welding machine 103 to move backward and reset. Then, the controller 104 controls the drive motor 202 to rotate in the reverse direction and automatically turn off. The output shaft of the drive motor 202 drives the screw 203 to rotate in the reverse direction. The screw 203 drives the moving block 204 and the reference block 201 to move upward. The reference block 201 supports the aluminum plate to move upward. The upward movement of the reference block 201 drives the transmission plate 403 to rotate in the reverse direction, and drives the pushing block 404 to move outward through the transmission plate 403. The pushing block 404 pushes the hinge rod 401 to rotate in the reverse direction, and the hinge rod 401 pulls the sliding block 301 and the correction block 302 to move outward and reset. The staff can then take out the welded aluminum plates. According to the above operation process, the automatic welding work of the aluminum plates can be continued.

[0035] Such as Figure 1 , Figure 2 and Figures 8-10As shown in the figure, it further includes a fixing frame 501, a small motor 502, a rotating block 503, a connecting block 504, a pushing block 505, a second torsion spring 506, an auxiliary wheel 507 and a compression spring 508. On the rear side of the top of the workbench 1, the fixing frames 501 are symmetrically connected by bolts on the left and right. The upper sides of the fixing frames 501 are both equipped with small motors 502. The small motors 502 are electrically connected to the controller 104. The output shafts of the small motors 502 are both symmetrically connected with rotating blocks 503 before and after. The connecting blocks 504 are both slidably connected to the rotating blocks 503. The pushing blocks 505 are rotatably connected between the two connecting blocks 504 on the same side. The pushing block 505 is L-shaped and can limit the side of the aluminum plate. The second torsion springs 506 are connected between the front and rear sides of the pushing block 505 and the corresponding connecting blocks 504. Two compression springs 508 are connected between the connecting block 504 and the corresponding rotating block 503. A plurality of auxiliary wheels 507 are rotatably connected to the outer sides of the bottoms of the pushing blocks 505.

[0036] As Figure 10 As shown in the figure, it further includes a pressing block 601, a pressing spring 602 and a pulley 603. The pressing blocks 601 are both slidably connected to the inner sides of the bottoms of the pushing blocks 505. Two pressing springs 602 are connected between the pressing blocks 601 and the pushing blocks 505. The pulleys 603 are rotatably connected to the inner sides of the pressing blocks 601.

[0037] After the aluminum plates are placed, aligned, and centered, the controller 104 can be operated to start the small motor 502. The output shaft of the small motor 502 rotates to drive the rotating block 503 to rotate, which in turn drives the connecting block 504 and the material pushing block 505 to rotate. All the components on the material pushing block 505 will rotate accordingly. The pressing block 601 and the pulley 603 rotate with the material pushing block 505. The pulley 603 will first contact the aluminum plate to assist the pressing block 601 and the material pushing block 505 to move. The pressing block 601 presses the aluminum plate, and the compression spring 508 is compressed accordingly. After the material pushing block 505 abuts against the aluminum plate, the rotating block 503 and the connecting block 504 continue to rotate, further compressing the compression spring 508. At the same time, the second torsion spring 506 deforms, and the material pushing block 505 is clamped to the side of the aluminum plate. The auxiliary wheel 507 contacts the top surface of the workbench 1 and plays an auxiliary moving role when the material pushing block 505 moves. The rotating block 503 continues to rotate, and the aluminum plate can be pushed inward by the material pushing block 505, making the two aluminum plates approach each other. The compression spring 508 can keep the material pushing block 505 under a downward force. After the rotating block 503 rotates to the limit position, the small motor 502 automatically pauses. At this time, the two aluminum plates are also in close contact, and the welding work of the aluminum plates can be carried out. The pressing block 601 presses the aluminum plate, which can ensure the stability of the aluminum plate during movement and welding. After the aluminum plates are welded, the controller 104 is operated to control the small motor 502 to rotate in the reverse direction and reset. The output shaft of the small motor 502 drives the rotating block 503 and the connecting block 504 to rotate in the reverse direction, which in turn drives the material pushing block 505 to move outward and rotate in the reverse direction, and the components on it are reset accordingly. The compression spring 508 will gradually rebound and reset, and the second torsion spring 506 will also rebound and reset, causing the material pushing block 505 to rotate in the reverse direction and separate from the aluminum plate. The compression spring 508 is separated from the aluminum plate, and the pressing spring 602 also rebounds and resets accordingly. In this way, the automatic feeding and pressing of the aluminum plates are completed.

[0038] As Figure 11 shown, it further includes a mounting bracket 701 and a material sliding roller 702. The mounting bracket 701 is connected to the front side of the reference block 201. A plurality of material sliding rollers 702 are evenly and rotatably connected to the mounting bracket 701. After the aluminum plates are welded, the aluminum plates are pushed forward, and the material sliding rollers 702 can rotate due to friction to assist the rapid pushing out of the aluminum plates.

[0039] As Figure 11 shown, it further includes a cleaning brush 8. The cleaning brush 8 is connected to both the left and right side walls of the reference block 201. After the reference block 201 corrects the side of the aluminum plate, the reference block 201 moves downward to drive the cleaning brush 8 to move downward. The cleaning brush 8 will clean the welding edge of the aluminum plate to avoid the influence of dust and impurities on the welding quality.
