Description

Technical Field

[0001] This utility model relates to the field of layer plate welding technology, and specifically to a limiting device for layer plate welding processing. Background Technology

[0002] Shelves are plate-shaped materials used to place materials. When used with shelves, they can be used to support and store goods. During the processing, steel shelves and shelf frames need to be connected by welding. In order to improve the accuracy of the connection between the shelf frame and the steel shelf, a limiting structure is usually used to limit the connection position between the shelf frame and the steel shelf.

[0003] During the welding process of the layer plates, it is usually necessary to use a limiting structure to limit the layer plates and the frame respectively. Commonly, the frame needs to be welded first before welding with the layer plates. However, during the welding process, the movement trajectory of the welding torch and the limiting structure that restricts the displacement of the layer plates and the frame will create an obstruction, affecting the welding process of the layer plates.

[0004] Therefore, a limiting device for layer plate welding is proposed to solve the problem that the limiting structure will obstruct the movement trajectory of the welding torch during welding, thus affecting the welding process of the layer plate. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the moving trajectory of the welding torch during welding and the limiting structure will cause obstruction during the welding process, which will affect the welding process of the layer plate. Therefore, a limiting device for the welding process of the layer plate is proposed.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a limiting device for layer plate welding processing, including a fixed plate, a steel layer plate and a frame. Support bars are fixedly connected to both sides of the upper end of the fixed plate, and support rods are fixedly connected to both sides of the upper end of the support bars. Connecting blocks are fixedly connected to the upper ends of the support rods, and connecting rods are fixedly connected between two opposing connecting blocks. A first motor is fixedly connected to one side of each of the two connecting blocks, and a first screw is fixedly connected to the output end of the first motor. A first slider is threaded onto the first screw, and one of the first sliders is fixedly connected to one side of... A second motor has a second screw fixedly connected to its output end, and a second slider fixedly connected to its output end. A welding gun is provided on the bottom side of the second slider. Air holes are evenly distributed on the upper end of the fixed plate. Vertical plates are fixedly connected to both sides of the fixed plate. Electric push rods are fixedly connected to the opposite sides of the two vertical plates. L-shaped clamping plates are fixedly connected to the output ends of the electric push rods. Electric telescopic rods are fixedly connected to the opposite sides of the two support bars. Pressure plates are fixedly connected to the output ends of the electric telescopic rods. The fixed plate is hollow inside, and an air pump is fixedly connected to the center of the bottom end of the fixed plate.

[0007] As a preferred technical solution of this utility model, an adjusting rod is threadedly connected to the L-shaped plate, and an extension plate is rotatably connected to the bottom end of the adjusting rod. By setting the adjusting rod, the extension plate can be driven to press down, thereby contacting the frame.

[0008] As a preferred technical solution of this utility model, a support ball is rotatably embedded at the bottom end of the extension plate, and the support ball contacts the frame. By setting the support ball, the frictional force when the extension plate contacts the frame can be reduced.

[0009] As a preferred technical solution of this utility model, a connecting sleeve is fixedly connected to both sides of the fixing plate, a sealing plate is inserted into the connecting sleeve, a first limiting strip is fixedly connected to both sides of the upper end of the sealing plate, a positioning rod is threadedly connected to the connecting sleeve, and the end of the positioning rod contacts the sealing plate. By setting the positioning rod, the sealing plate can be limited.

[0010] As a preferred technical solution of this utility model, a second limiting strip is fixedly connected to one side of the bottom end of the sealing plate. The second limiting strip is located inside the fixing plate. By setting the second limiting strip, the area of ​​communication between the cavity and the air hole inside the fixing plate can be reduced, thereby stabilizing the adsorption of the steel layer plate.

[0011] This utility model has the following advantages: by using an electric push rod and an L-shaped clamping plate in conjunction with an electric telescopic rod and a pressure plate, the steel shelf and frame can be limited. Then, the first screw and the second screw drive the second slider and the bottom welding gun to move in three dimensions, which can weld the inner side of the frame to the steel shelf. Then, by extending and retracting the electric telescopic rod, the frame and the steel shelf can be moved, thereby completing the external welding of the steel shelf and the frame. This improves the limiting effect on the steel shelf during welding and reduces the obstruction of the L-shaped clamping plate and the pressure plate during the welding process.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The illustrated limiting device for layer plate welding includes a fixed plate 1, a steel layer plate 2, and a frame 3. Support bars 4 are fixedly connected to both sides of the upper end of the fixed plate 1. Support rods 5 are fixedly connected to both sides of the upper end of the support bars 4. Connecting blocks 7 are fixedly connected to the upper ends of the support rods 5. Connecting rods 6 are fixedly connected between two opposing connecting blocks 7. A first motor is fixedly connected to one side of each connecting block 7. The first and second motors cooperate to move a second slider 11. A third motor is installed inside the second slider 11. A rotating disk is fixedly connected to the bottom of the third motor. A connecting frame is fixedly connected to the bottom of the rotating disk. A fourth motor is fixedly connected to the bottom of the connecting frame. A rotating column is fixedly connected to one side of the fourth motor. The bottom of the rotating column is fixedly connected to a welding torch 12. The welding torch 12 is connected to an external gas supply device and works with an ignition device to weld the frame 3 and the steel layer plate 2. A first screw 8 is fixedly connected to the output end of the first motor. A first slider 9 is threaded onto the first screw 8. One of the first sliders 9... A second motor is fixedly connected to the side, and a second screw 10 is fixedly connected to the output end of the second motor. A second slider 11 is fixedly connected to the output end of the second screw 10. A welding gun 12 is provided on the bottom side of the second slider 11. Air holes 13 are evenly opened on the upper end of the fixed plate 1. Vertical plates 14 are fixedly connected to both sides of the fixed plate 1. Electric push rods 15 are fixedly connected to the opposite sides of the two vertical plates 14. When the electric push rods 15 extend, they can drive the L-shaped card plate 16 to limit the frame 3 and the two sides of the steel plate 2. 5. An L-shaped card plate 16 is fixedly connected to the output end. An electric telescopic rod 17 is fixedly connected to one side of each of the two support bars 4. When the electric telescopic rod 17 extends, it can drive the pressure plate 18 to limit the frame 3 and the other two sides of the steel layer plate 2. The pressure plate 18 is fixedly connected to the output end of the electric telescopic rod 17. The fixed plate 1 is hollow inside. An air pump 19 is fixedly connected to the center of the bottom end of the fixed plate 1. The air pump 19 draws gas from the cavity of the fixed plate 1, making the fixed plate 1 negative pressure, so as to adsorb the steel layer plate 2.

[0018] The L-shaped plate 16 is threaded with an adjusting rod 20, and the bottom end of the adjusting rod 20 is rotatably connected to an extension plate 21. By rotating the adjusting rod 20, the extension plate 21 can be limited to the upper side of the frame 3, and the upper width of the L-shaped plate 16 and the extension plate 21 is less than the width of the frame 3.

[0019] Among them, the bottom end of the extension plate 21 is rotatably embedded with a support ball 22, which contacts the frame 3. The movement friction between the extension plate 21 and the frame 3 is reduced by setting the support ball 22.

[0020] The fixed plate 1 is fixedly connected to both sides of the connecting sleeve 23, and the sealing plate 24 is inserted into the connecting sleeve 23. The upper end of the sealing plate 24 is fixedly connected to both sides of the first limiting strip 25. The connecting sleeve 23 is threadedly connected to the positioning rod 27. The end of the positioning rod 27 contacts the sealing plate 24. By setting the positioning rod 27, the relative position of the sealing plate 24 and the fixed plate 1 can be limited, thereby changing the unfolded area of ​​the air hole 13 and reducing the energy consumption of the air pump 19.

[0021] The sealing plate 24 has a second limiting strip 26 fixedly connected to one side of its bottom end. The second limiting strip 26 is located inside the fixing plate 1. By setting the second limiting strip 26, the bottom gap of the sealing plate 24 can be reduced.

[0022] Working principle: After the steel shelf 2 and frame 3 are aligned, they are placed on the fixed plate 1. Then, the electric push rod 15 extends to press the L-shaped clamping plate 16 against the edges of the steel shelf 2 and frame 3. The electric telescopic rod 17 then extends, and the pressure plate 18 contacts the other two sides of the steel shelf 2 and frame 3. Further rotation of the adjusting rod 20 causes the support ball 22 to contact the upper side of the frame 3, providing a limit on the upper side of the frame 3. Then, the relative position of the sealing plate 24 and the fixed plate 1 is adjusted, and the positioning rod 27 is used for limiting. Then, the air pump 19 is started, and the rotation of the first screw 8 and the second screw 10 causes the second slider 11 to move in four positions. The connecting blocks 7 move to weld the inner side of the frame 3 to the steel plate 2. After the inner side welding is completed, one of the electric telescopic rods 17 extends and the other electric telescopic rod 17 retracts, and the air pump 19 stops. At this time, the frame 3 and the steel plate 2 move, which can cause part of the frame 3 and the steel plate 2 to be unfolded. Then the outer half of the steel plate 2 and the frame 3 are welded. After the welding is completed, the electric telescopic rod 17 can be operated in reverse to weld the other half of the steel plate 2 and the frame 3. This can provide a limit while reducing the blockage between the welding torch 12 and the limit structure during the welding process, thus improving the welding efficiency.
