[0002] Alu-zinc sheets are widely used in many fields, mainly including construction, home appliances, automobiles, agriculture, forestry and animal husbandry. In the construction field, galvanized sheets are often used for roofs, exterior walls, soundproof walls, pipes, etc., because of their good corrosion resistance and weather resistance, they can improve the beauty and durability of buildings. In home appliance manufacturing, galvanized sheets are used for microwave oven shells, washing machine shells, refrigerator back panels, air conditioner shells, etc., and are favored for their corrosion resistance and easy processing. In the automotive industry, galvanized sheets are used for fuel tanks, exhaust pipes, mufflers and other components, because of their light weight, high strength, corrosion resistance and other characteristics to meet the needs of automobile manufacturing. In addition, galvanized sheets are also used for the transportation of agricultural products, irrigation of orchards and farmland, enclosures of reservoirs, and the construction of livestock sheds.

The position of the slider 45 is then fixed by bolts so that the moving frame 46 is located on the outside of the limiting component 3. After the four plates 2 are inserted into the limiting component 3 and aligned, the one-way screw 47 is driven to rotate by the built-in motor of the moving frame 46, and the moving block 48 drives the welding head 411 to move. The driving motor 42 drives the disc 43 to rotate, so that the welding head 411 is close to the contact position of the two plates 2. The electric push rod 49 is used to make the welding head 411 close to the contact position, 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 limit assembly 3 also includes a first bidirectional screw 39, and 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, and the outer end of the horizontal frame 32 connected to the vertical frame 31 is fixed with a connecting frame 33, and the connecting frame 33 is slidably sleeved on the outer side of the vertical frame 31. The backs of the inner slide rail 34 and the outer slide rail 35 are both provided with a moving notch 311. The second clamping block 38 is fixed with a plug plate 37 on the side facing the first clamping block 36, and the plug plate 37 slides through the first clamping block 36 and the moving notch 311. The position where the plug plate 37 of the inner slide rail 34 passes through the moving notch 311 is fixed with a slide bar 312. The top of the slide bar 312 slides through the plug plate 37 of the outer slide rail 35, and the top of the slide bar 312 that passes through the plug plate 37 is sleeved with a return spring 313, and the bottom of the return spring 313 is fixedly connected to the plug plate 37 of the outer slide rail 35, and the outer side of the inner slide rail 34 is rotatably mounted with a second bidirectional screw 314 through a bearing seat, and a screw hole is opened at the bottom of the slide bar 312, and the bottom of the slide bar 312 passes through the plug plate 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 kept connected by the slide bar 312, and at the same time, a certain distance and elasticity are maintained by the return spring 313, and the plate 2 can be squeezed and limited after the plate 2 is inserted into the first clamping block 36 and the second clamping block 38 between the inner slide rail 34 and the outer slide rail 35. The second bidirectional screw 314 is moved to drive the two slide rails to move, and at the same time, the positions of the plug plates 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 plates 2 of different widths, so 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 plates 2 without being too close to the welding parts of the plates 2. The first bidirectional screw 39 inside the vertical frame 31 and the horizontal frame 32 can be rotated to drive the inner and outer slide rails 34 and the outer slide rails 35 to move synchronously through the connecting seat 310, and change the distance between the two groups of inner and outer slide rails 34 and 35 in the vertical and horizontal directions, so as to facilitate the use of plates 2 of different lengths. Because when the galvanized sheet is welded into a frame structure, the dimensions of the four sides are not necessarily the same, and the welding parts can be welded together. The upper and lower surfaces and the left and right surfaces are 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, and 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 with the adjacent plates 2 after insertion. In this part of the content, the connecting seat 310 in the vertical frame 31 is fixedly connected to the inner slide rail 34, and the connecting seat 310 in the horizontal frame 32 is rotatably connected to the inner slide rail 34. Here, the plate 2 can be inserted into the limiting component 3 at the top of the vertical frame 31, and then the connecting frame 33 slides along the vertical frame 31 to adjust the positions of the limiting components 3 on both sides. After inserting the plate 2 at the bottom and both sides, the plates 2 on both sides are contacted with the bottom plate 2, and then the first bidirectional screw 39 in the horizontal frame 32 is rotated.At this time, the plate 2 rotates due to the extrusion of the bottom and can be adjusted to a triangular structure. The three groups of plates 2 are welded together with some connecting strips or connecting pieces, and the position of the connecting frame 33 can be fixed by bolts.

[0045] When using the device, the limiting assembly 3 is pulled out of the welding table 1, and the plate 2 is inserted into the limiting assembly 3. The four plates 2 form a frame. The inner slide rail 34 and the outer slide rail 35 are connected by the slide rod 312, and a certain distance and elasticity are maintained by the reset spring 313. After the plate 2 is inserted into the first clamping block 36 and the second clamping block 38 between the inner slide rail 34 and the outer slide rail 35, the plate 2 can be squeezed and limited. The second bidirectional screw 314 is rotated to drive the two slide rails to move. At the same time, the positions of the plug plate 37 and the first clamping block 36 and the second clamping block 38 inside the inner slide rail 34 and the outer slide rail 35 are adjusted. The adjustment is made according to the plates 2 of different widths to keep the two groups of first clamping blocks 36 and second clamping blocks 38 movable. By rotating the first bidirectional screw 39 inside the vertical frame 31 and the horizontal frame 32 so as to squeeze and contact the inner and outer sides of the plate 2 without getting too close to the welding part of the plate 2, 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 sets of inner slide rails 34 and outer slide rails 35 in the vertical and horizontal directions can be changed, which is convenient for using plates 2 of different lengths. Because when the galvanized sheet is welded into a frame structure, the dimensions of the four sides are not necessarily the same, 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 the two ends of the plate 2 can be aligned with each other after insertion. Adjacent plates 2 are in contact. In this part, the connecting seat 310 in the vertical frame 31 is fixedly connected to the inner slide rail 34, while the connecting seat 310 in the horizontal frame 32 is rotatably connected to the inner slide rail 34. Here, the plate 2 can be inserted into the limiting component 3 at the top of the vertical frame 31 without inserting it, and then slide along the vertical frame 31 through the connecting frame 33 to adjust the position of the limiting components 3 on both sides. After inserting the plate 2 at the bottom and both sides, the plate 2 on both sides is brought into contact with the bottom plate 2, and then the first bidirectional screw 39 in the horizontal frame 32 is rotated. At this time, the plate 2 rotates due to the extrusion effect at the bottom, and can be adjusted to a triangular structure. The three groups of plates 2 are welded with some connecting strips or connecting parts. The position of the connecting frame 33 can be adjusted by The slider 45 is fixed by bolts, and then the position of the slider 45 is fixed by bolts, so that the moving frame 46 is located on the outside of 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 built-in motor of the moving frame 46, and the moving block 48 drives the welding head 411 to move, and the disc 43 is driven to rotate by the driving motor 42, so that the welding head 411 is close to the contact position of the two plates 2. The welding head 411 is close to 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 limit component 3, thereby improving the overall welding efficiency.
