Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and specifically to a welding device and a welding method for aluminized zinc plates. Background Art

[0002] Aluminized zinc plates are widely used in multiple fields, mainly including construction, household appliances, automobiles, agriculture, forestry, animal husbandry, etc. In the construction field, aluminized zinc plates are commonly used for roofing, exterior walls, sound insulation walls, pipelines, etc. Because of their good corrosion resistance and weather resistance, they can improve the aesthetics and durability of buildings. In household appliance manufacturing, aluminized zinc plates are used for the outer shells of microwave ovens, washing machines, the back panels of refrigerators, the outer shells of air conditioners, etc., and are favored because of their corrosion resistance and easy processability. In the automotive industry, aluminized zinc plates are used for components such as fuel tanks, exhaust pipes, and mufflers, and meet the requirements of automobile manufacturing because of their light weight, high strength, and corrosion resistance. In addition, aluminized zinc plates are also used for the transportation of agricultural products, the irrigation of orchards and farmlands, the enclosure of water storage tanks, and the construction of livestock sheds.

[0003] Because aluminized zinc plates are widely used, they need to be processed into different structural forms in combination with welding technology during actual use. A common example is the box shape, which requires welding of the right-angle sides of multiple plates. The commonly used methods are spot welding or fusion welding. When processing the welding of multiple aluminized zinc plates in the prior art, the first thing to consider is the contact and angle between two plates, which requires fasteners for fixation, and only one plate can be welded at a time, resulting in low efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a welding device and a welding method for aluminized zinc plates to solve the problems raised in the above background art. The structure of the present invention is novel. Under the action of the limiting component, multiple plates can be inserted and clamped to form a complete frame structure. The two ends of each plate are in contact with and perpendicular to the adjacent plates, so as to facilitate the unified welding processing along the right-angle sides by the welding component, improve the welding efficiency, maintain the stability of the plates during the process, and reduce the inconvenience of manual intervention.

[0005] To achieve the above object, the present invention is realized through the following technical solutions: A welding device for aluminized zinc plates includes a welding table, and a limiting component is arranged on the top of the welding table. The limiting component includes a horizontal frame, and a vertical frame is slidably installed on the middle surface of the horizontal frame.

[0008] Further, the welding component further includes a driving motor. The bearing bracket is fixed with a driving motor on the back of the disc, and the output end of the driving motor is fixedly connected to the disc. A chute is opened at the installation position of the disc corresponding to the moving frame, and a slider is slidably connected inside the chute. The moving frame is fixedly connected to the slider.

[0009] Further, a one-way screw rod is rotatably installed inside the moving frame through a bearing. The moving block is threadedly sleeved on the surface of the one-way screw rod. An electric push rod is fixed on the outer surface of the moving block, and an extension end of the electric push rod is fixed with a connecting plate. The welding head is fixedly connected to the connecting plate.

[0010] Further, the limiting component further includes a first bidirectional screw rod. The first bidirectional screw rod is rotatably installed inside both the vertical frame and the horizontal frame through a bearing. The connecting seats inside the vertical frame and the horizontal frame are all threadedly sleeved on the surface of the first bidirectional screw rod. A connecting frame is fixed at the outer end where the horizontal frame is connected to the vertical frame, and the connecting frame is slidably sleeved outside the vertical frame.

[0011] Further, moving notches are formed on the back surfaces of the inner slide rail and the outer slide rail. A plug board is fixed on one side of the second clamping block facing the first clamping block, and the plug board slidably passes through the first clamping block and the moving notch.

[0012] Further, a slide bar is fixed at the position where the plug board of the inner slide rail passes through the moving notch.

[0014] A welding method for aluminized zinc plates, the welding method comprising the following steps:

[0015] (1) Adjusting dimensions: Adjust the dimensions of the four insertion positions of the limiting component to be adapted to the aluminized zinc plate. Insert the aluminized zinc plate into the four surfaces of the limiting component. The first clamping block and the second clamping block on the same surface are respectively in contact with the inner surface and the outer surface of the aluminized zinc plate, and the aluminized zinc plate is elastically clamped and limited by the first clamping block and the second clamping block;

[0016] (2) Adjusting dimensions: Adjust the dimensions of the four insertion positions of the limiting component to be adapted to the aluminized zinc plate. Keep a certain distance between the first clamping block and the second clamping block and the two welding positions on both sides of the aluminized zinc plate, and the adjacent aluminized zinc plates are in contact, and the contact part is the welding edge;

[0017] (3) Welding treatment: By rotating the disc of the welding component, drive the welding head to rotate around the limiting component and the aluminized zinc plate, and the welding head horizontally moves in the moving frame. When passing through the joint position of two aluminized zinc plates, spot welding is performed on it;

[0018] (4) Completing and sending out: After welding is completed, slide the limiting component out along the surface of the welding table, and pull out the aluminized zinc plates welded together from the open end of the limiting component.

[0019] Advantages of the present invention:

[0020] 1. In the present invention, the slider is moved along the chute, and then the position of the slider is fixed by a bolt, so that the moving frame is located outside the limiting component. After four plates are inserted into the limiting component and aligned, the unidirectional screw is rotated by the motor built in the moving frame, the moving block drives the welding head to move, the disc is rotated by the driving motor, which facilitates the welding head to approach the contact position of the two plates. The welding head is brought close to the contact position by the electric push rod, and spot welding is completed during the translation process. When the disc rotates, the electric push rod retracts the welding head to avoid collision with the limiting component.

[0021] 2. The inner slide rail and the outer slide rail of the present invention are connected by a slide rod, and at the same time, a certain distance and elasticity are maintained by a return spring, so that the plate can be squeezed and limited after being inserted between the first clamping block and the second clamping block of the inner slide rail and the outer slide rail.

[0022] 3. By rotating the second bidirectional screw of the present invention, two slide rails are driven to move, and at the same time, the positions of the insertion plates inside the inner slide rail and the outer slide rail, as well as the first clamping block and the second clamping block, are adjusted. According to plates of different widths, while ensuring that the two groups of first clamping blocks and second clamping blocks can squeeze and contact the inner and outer sides of the plate, they will not be too close to the welding part of the plate. By rotating the first bidirectional screw inside the vertical frame and the horizontal frame, the inner slide rail and the outer slide rail can be driven to move synchronously through the connecting seat, changing the distance between the two groups of inner slide rails and outer slide rails in the vertical and horizontal directions, which is convenient for using plates of different lengths.

[0023] 4. The limiting component of the present invention is slidably installed on the first slide rail of the welding table through a sliding frame, and can be pulled out along the first slide rail, which is convenient for manually inserting the plate into the limiting component, and can also take out the plate from the limiting component after the plate is welded. During the welding process, the bottom of the limiting component is supported by a supporting plate to maintain stability, and by sliding the supporting plate along the second slide rail, the limiting component and the plate can be assisted to be sent out.

[0024] Compared with the prior art, the present invention, under the action of the limiting component, can insert and clamp multiple plates to form a complete frame structure. The two ends of each plate are in contact with the adjacent plates and are vertically corresponding, so that it is convenient for the welding component to uniformly weld along the right-angle sides, improving the welding efficiency, maintaining the stability of the plate during the process, and reducing the inconvenience of manual intervention.

A welding component 4 is provided on the back of the welding table 1 corresponding to the limiting component 3. The welding component 4 includes a disc 43. The disc 43 is provided on the back of the vertical frame 31 and the horizontal frame 32. The center of the disc 43 is on the same straight line as the middle position of the vertical frame 31. A bearing bracket 41 is fixed at the position of the welding table 1 corresponding to the back of the disc 43. The disc 43 is rotatably installed on the bearing bracket 41. A moving frame 46 is installed on the surface of the disc 43. A moving block 48 is slidably connected inside the moving frame 46. A welding head 411 is installed on the outside of the moving block 48. When using the device, the limiting component 3 is pulled out of the welding table 1, the plate 2 is inserted into the limiting component 3, and four plates 2 form a frame. The limiting component 3 adjusts its size to match the length and width of the plate 2. The welding component 4 rotates around the limiting component 3, and the edges where each plate 2 meets are welded, improving the overall welding efficiency.

[0042] In this embodiment, three first slide rails 11 are fixed on the surface of the welding table 1. Slide brackets 15 are fixed at both ends of the horizontal frame 32 and the bottom of the vertical frame 31, and the slide brackets 15 are slidably mounted on the surfaces of the first slide rails 11. A second slide rail 12 is fixed between the two groups of first slide rails 11 on the welding table 1. A support plate 13 is arranged on the top of the second slide rail 12. The support plate 13 contacts the bottom of the limiting component 3. A spring telescopic rod 14 is fixed at the bottom of the support plate 13, and the bottom of the spring telescopic rod 14 slides along the second slide rail 12 through a sliding seat. The limiting component 3 is slidably mounted on the first slide rails 11 of the welding table 1 through the slide brackets 15 and can be pulled outwards along the first slide rails 11, which is convenient for manually inserting the plate 2 into the limiting component 3, and the plate 2 can also be taken out of the limiting component 3 after the welding is completed. During the welding process, the bottom of the limiting component 3 is supported by the support plate 13 to maintain stability. By sliding the support plate 13 along the second slide rail 12, the limiting component 3 and the plate 2 can be assisted to be sent out.

[0043] In this embodiment, the welding component 4 further includes a driving motor 42. The driving motor 42 is fixed on the back of the bearing frame 41 corresponding to the disc 43, and the output end of the driving motor 42 is fixedly connected to the disc 43. A chute 44 is opened at the installation position of the disc 43 corresponding to the moving frame 46, and a slider 45 is slidably connected inside the chute 44. The moving frame 46 is fixedly connected to the slider 45. A one-way screw rod 47 is rotatably installed inside the moving frame 46 through a bearing. The moving block 48 is threadedly sleeved on the surface of the one-way screw rod 47. An electric push rod 49 is fixed on the outer surface of the moving block 48, and the extending end of the electric push rod 49 is fixedly connected to a connecting plate 410. The welding head 411 is fixedly connected to the connecting plate 410. Move the slider 45 along the chute 44, and then fix the position of the slider 45 through a bolt, so that the moving frame 46 is located outside the limiting component 3. After the four plates 2 are inserted into the limiting component 3 and aligned, the one-way screw rod 47 is rotated by the motor built in the moving frame 46, and the moving block 48 drives the welding head 411 to move. The disc 43 is driven to rotate by the driving motor 42, which is convenient for the welding head 411 to approach the contact position of the two plates 2. The welding head 411 is made to approach the contact position through the electric push rod 49, and the spot welding work is completed during the translation process. When the disc 43 rotates, the electric push rod 49 retracts the welding head 411 to avoid collision with the limiting component 3.

[0044] In this embodiment, the limiting component 3 further includes a first bidirectional screw 39. The first bidirectional screw 39 is rotatably installed inside the vertical frame 31 and the horizontal frame 32 through bearings. The connecting seats 310 inside the vertical frame 31 and the horizontal frame 32 are threadedly sleeved on the surface of the first bidirectional screw 39. The outer end of the connection between the horizontal frame 32 and the vertical frame 31 is fixed with a connection frame 33, and the connection frame 33 is slidably sleeved outside the vertical frame 31. Moving notches 311 are formed on the back surfaces of the inner slide rail 34 and the outer slide rail 35. A plug board 37 is fixed on the side of the second clamping block 38 facing the first clamping block 36, and the plug board 37 slidably passes through the first clamping block 36 and the moving notch 311. A slide rod 312 is fixed at the position where the plug board 37 of the inner slide rail 34 passes through the moving notch 311. The top of the slide rod 312 slidably passes through the plug board 37 of the outer slide rail 35. A return spring 313 is sleeved on the top of the slide rod 312 passing through the plug board 37, and the bottom of the return spring 313 is fixedly connected to the plug board 37 of the outer slide rail 35. A second bidirectional screw 314 is rotatably installed outside the inner slide rail 34 through a bearing seat. A threaded hole is formed at the bottom of the slide rod 312, and the bottom of the slide rod 312 passes through the plug board 37 and is threadedly sleeved on the surface of the second bidirectional screw 314. The inner slide rail 34 and the outer slide rail 35 are connected by the slide rod 312 and at the same time maintain a certain distance and elasticity through the return spring 313. After the sheet material 2 is inserted between the first clamping block 36 and the second clamping block 38 of the inner slide rail 34 and the outer slide rail 35, the sheet material 2 can be squeezed and limited. By rotating the second bidirectional screw 314, the two slide rails are driven to move, and at the same time, the positions of the plug boards 37 inside the inner slide rail 34 and the outer slide rail 35 and the first clamping block 36 and the second clamping block 38 are adjusted. According to the sheet material 2 of different widths, the adjustment is made to ensure that the two groups of first clamping blocks 36 and second clamping blocks 38 can squeeze and contact the inner and outer sides of the sheet material 2 while not being too close to the welding part of the sheet material 2. By rotating the first bidirectional screw 39 inside the vertical frame 31 and the horizontal frame 32, the inner slide rail 34 and the outer slide rail 35 can be driven to move synchronously through the connecting seat 310, and the distance between the two groups of inner slide rails 34 and outer slide rails 35 in the vertical and horizontal directions can be changed, which is convenient for using sheet materials 2 of different lengths. Because when the aluminized zinc plate is welded into a frame structure, the four sides are not necessarily of the same size, and the upper and lower sides and the left and right sides can be the same respectively. Here, it is necessary to separately adjust the first bidirectional screw 39 inside the vertical frame 31 and the horizontal frame 32 to adjust the positions of the inner slide rail 34 and the outer slide rail 35 in each direction, so that both ends of the sheet material 2 can contact the adjacent sheet materials 2 after being inserted. In this part of the content, the connecting seat 310 inside the vertical frame 31 is fixedly connected to the inner slide rail 34, while the connecting seat 310 inside the horizontal frame 32 is rotatably connected to the inner slide rail 34. Here, the sheet material 2 can be not inserted into the limiting component 3 at the top of the vertical frame 31, and then the position of the limiting components 3 on both sides can be adjusted by sliding the connection frame 33 along the vertical frame 31. After the sheet materials 2 are inserted at the bottom and on both sides, the sheet materials 2 on both sides are made to contact the bottom sheet material 2, and then the first bidirectional screw 39 inside the horizontal frame 32 is rotated.At this time, the sheet 2 rotates due to the extrusion effect at the bottom and can be adjusted into a triangular structure. Some connecting bars or connectors are used to weld the three groups of sheets 2, and the position of the connecting frame 33 can be fixed by bolts.

[0045] When using the device, pull out the limit component 3 from the welding table 1, insert the plate 2 into the inside of the limit component 3. The four plates 2 form a frame. The inner slide rail 34 and the outer slide rail 35 are kept connected by the slide bar 312, and at the same time, a certain distance and elasticity are maintained by the return spring 313. After the plate 2 is inserted between the first clamping block 36 and the second clamping block 38 inside the inner slide rail 34 and the outer slide rail 35, the plate 2 can be squeezed and limited. Rotate the second double-headed screw 314 to drive the two slide rails to move, and at the same time adjust the positions of the insertion plates 37 inside the inner slide rail 34 and the outer slide rail 35, as well as the first clamping block 36 and the second clamping block 38. Adjust according to the plates 2 of different widths to ensure that the two groups of the first clamping block 36 and the second clamping block 38 can squeeze and contact the inner and outer sides of the plate 2, while not being too close to the welding part of the plate 2. Rotate the first double-headed screw 39 inside the vertical frame 31 and the horizontal frame 32, and the inner slide rail 34 and the outer slide rail 35 can be driven to move synchronously through the connecting seat 310, changing the distance between the two groups of the inner slide rail 34 and the outer slide rail 35 in the vertical and horizontal directions, which is convenient for using plates 2 of different lengths. Because when the aluminized zinc plate is welded into a frame structure, the four sides are not necessarily of the same size. It can be that the upper and lower surfaces are the same respectively, and the left and right surfaces are the same respectively. Here, it is necessary to separately adjust the first double-headed screw 39 inside the vertical frame 31 and the horizontal frame 32 to adjust the positions of the inner slide rail 34 and the outer slide rail 35 in each direction, so that the two ends of the plate 2 can contact the adjacent plates 2 after being inserted. In this part of the content, the connecting seat 310 inside the vertical frame 31 is fixedly connected to the inner slide rail 34, while the connecting seat 310 inside the horizontal frame 32 is rotatably connected to the inner slide rail 34. Here, the plate 2 can not be inserted into the limit component 3 at the top of the vertical frame 31, and then the position of the two limit components 3 can be adjusted by sliding the connecting frame 33 along the vertical frame 31. After inserting the plates 2 at the bottom and on both sides, make the plates 2 on both sides contact the bottom plate 2. Then rotate the first double-headed screw 39 inside the horizontal frame 32. At this time, the plate 2 rotates due to the extrusion at the bottom and can be adjusted into a triangular structure. Some connecting bars or connecting pieces are used to weld the three groups of plates 2. The position of the connecting frame 33 can be fixed by bolts. Move the slider 45 along the chute 44, and then fix the position of the slider 45 by bolts, so that the moving frame 46 is located outside the limit component 3. After the four plates 2 are inserted into the limit component 3 and aligned, the one-way screw 47 is driven to rotate by the motor built in the moving frame 46, and the moving block 48 drives the welding head 411 to move. The disc 43 is driven to rotate by the driving motor 42, which is convenient for the welding head 411 to approach the contact position of the two plates 2. The welding head 411 is made to approach the contact position by the electric push rod 49, and the spot welding work is completed during the translation process. When the disc 43 rotates, the electric push rod 49 retracts the welding head 411 to avoid collision with the limit component 3, improving the overall welding efficiency.
