Technical Field

[0001] The utility model relates to the technical field of welding devices, and specifically, to a welding device for control cabinet plates. Background Technique

[0002] A control cabinet is assembled with switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a panel according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, be convenient for maintenance, not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be switched on or off manually or automatically. In case of a fault or abnormal operation, the protective electrical appliance is used to cut off the circuit or give an alarm. The measuring instruments can display various parameters during operation, and some electrical parameters can also be adjusted to prompt or send a signal for deviation from the normal working state.

[0003] During the production process of traditional control cabinet cabinets, after the processing of each board surface of the cabinet, it is necessary to preliminarily connect the board surfaces of the cabinet through several welding points, and then completely weld the positions of the connection seams to assemble them into a frame-shaped cabinet. Then, components such as partitions, rear covers and cabinet doors are installed on the cabinet. During the use of the cabinet welding device, it is not convenient to limit the support and adjust the positioning between the side plates and the bottom plate of the cabinet. Generally, it is manually spliced by workers, which affects the welding accuracy. In view of this, we propose a welding device for control cabinet plates. Summary of the Invention

A limiting component is arranged on the vertical section of the L-shaped clamping plate.

[0007] As a further improvement of this technical solution, the limiting component includes a through groove opened on the side wall of the vertical section of the L-shaped clamping plate. A sliding plate is slidably connected to the inner wall of the through groove. Two guide rods are fixedly connected to one side of the L-shaped clamping plate.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

Embodiment

[0026] Please refer to Figure 1 and Figure 2As shown in the figure, this embodiment provides a welding device for the control cabinet board, including a processing table 1. Above the processing table 1, there is a vertical plate support mechanism 2. The vertical plate support mechanism 2 vertically places the side panel of the control cabinet above the processing table 1. At the position below the vertical plate support mechanism 2 on the processing table 1, there is a docking mechanism 3. Near the middle position on one side of the processing table 1, a welding robot 4 is installed. The docking mechanism 3 limits the side panel of the control cabinet and the bottom panel of the control cabinet placed flat on the upper surface of the processing table 1. After vertically placing the side panel of the control board on the upper surface of the bottom panel of the control cabinet, the lower end surface of the side panel of the control cabinet coincides with the side edge of the upper surface of the bottom panel of the control cabinet close to the welding robot 4. Then, the welding robot 4 welds and fixes the side panels of the side panel of the control cabinet and the bottom panel that coincide. During the welding process, there is no need for manual splicing and stabilizing of the boards, which improves the welding accuracy.

[0027] In order to place the bottom panel of the control cabinet at a predetermined position on the processing table 1, so that after vertically placing the side panel of the control cabinet on the upper surface of the bottom panel of the control cabinet, it is convenient for the lower end surface of the side panel of the control cabinet to coincide with the side edge of the upper surface of the bottom panel of the control cabinet close to the welding robot 4, and it is convenient for the welding robot 4 to weld and fix the two boards. The structure of the docking mechanism 3 is refined as follows. Refer to Figure 5 , the docking mechanism 3 includes an installation cavity opened inside the processing table 1. Inside the installation cavity, a second lead screw 31 is rotatably connected. On one side of the processing table 1, a motor 32 for driving the second lead screw 31 to rotate is installed. The second lead screw 31 is provided with a positive thread and a reverse thread. Connecting plates 33 are threadedly connected to both the positive thread and the reverse thread. Two moving grooves 34 communicating with the installation cavity are opened at the top of the processing table 1. The two connecting plates 33 are respectively slidably arranged inside the two moving grooves 34. The upper ends of the connecting plates 33 are fixedly connected with L-shaped clamping plates 35. After horizontally placing the bottom panel of the control cabinet on the upper surface of the processing table 1 at the position between the two L-shaped clamping plates 35, the output shaft of the motor 32 is made to drive the second lead screw 31 to rotate. Through the threaded connection of the two connecting plates 33 with the positive thread and the reverse thread respectively, the two connecting plates 33 horizontally slide along the inner walls of the moving grooves 34. The connecting plates 33 drive the L-shaped clamping plates 35 to move synchronously. When one of the L-shaped clamping plates 35 contacts the side of the bottom panel of the control cabinet, this L-shaped clamping plate 35 pushes the bottom panel of the control cabinet in the direction close to the other L-shaped clamping plate 35 until the two L-shaped clamping plates 35 respectively cooperate with the two sides of the bottom panel of the control cabinet by extrusion, restricting the horizontal movement of the bottom panel of the control cabinet in the direction close to or away from the motor 32, and completing the preliminary limitation of the bottom panel of the control cabinet.

[0028] After the two L-shaped clamping plates 35 are respectively in pressing fit with both sides of the bottom plate of the control cabinet, the bottom plate of the control cabinet is horizontally pushed in the direction close to the welding robot 4 to adjust the position of the bottom plate of the control cabinet. By providing a limit component 36 on the vertical section of the L-shaped clamping plate 35, the closest position that the bottom plate of the control cabinet can reach to the welding robot 4 is defined, which facilitates moving the bottom plate of the control cabinet to a predetermined position. The structure of the limit component 36 is refined as follows. Refer to Figure 6 and Figure 7 , the limit component 36 includes a through groove 361 opened on the side wall of the vertical section of the L-shaped clamping plate 35. A sliding plate 362 is slidably connected to the inner wall of the through groove 361. Two guide rods 363 are fixedly connected to one side of the L-shaped clamping plate 35. One end of the guide rod 363 penetrates through the side wall of the sliding plate 362 and is fixedly connected to an end plate 364. A spring 365 is fixedly connected between the end plate 364 and the sliding plate 362. The spring 365 is sleeved outside the guide rod 363. A limit frame 366 is fixedly connected to the side of the sliding plate 362 close to the welding robot 4. The limit frame 366 is in sliding contact with the side of the L-shaped clamping plate 35 close to the welding robot 4. The bottom plate of the control cabinet is horizontally pushed in the direction close to the welding robot 4. At this time, the end of the limit frame 366 close to the welding robot 4 is located between the two L-shaped clamping plates 35. The bottom plate of the control cabinet moving horizontally along the side wall of the L-shaped clamping plate 35 can contact the limit frame 366. When the bottom plate of the control cabinet contacts the limit frame 366, stop pushing the bottom plate of the control cabinet, and place the bottom plate of the control cabinet at a predetermined position on the processing table 1, which facilitates making the lower end surface of the side panel of the control cabinet coincide with the side close to the welding robot 4 on the upper surface of the bottom plate of the control cabinet, and facilitates the welding robot 4 to weld and fix the two plates.

[0029] To define the position of the side panel of the control cabinet, make the lower end surface of the side panel of the control cabinet coincide with the side close to the welding robot 4 on the upper surface of the bottom plate of the control cabinet, and facilitate the welding robot 4 to weld and fix the two plates. The following part of the structure of the vertical plate support mechanism 2 is refined as follows. Refer to Figure 3 and Figure 4, the vertical plate support mechanism 2 includes a positioning frame 21 fixedly connected to the upper surface of the processing table 1. One side of the positioning frame 21 close to the welding robot 4 is hinged with a flipping frame 22. One end of the flipping frame 22 far from the hinge joint with the positioning frame 21 is fixedly connected with a buckle lock, and the buckle lock movably clamps the flipping frame 22 and the positioning frame 21. A pressing frame 23 is slidably arranged inside the positioning frame 21. A number of rollers 24 are vertically and arrayedly rotatably connected to the sides of the pressing frame 23 and the flipping frame 22 close to each other. Insert the side panel of the control cabinet vertically downward into the position between the pressing frame 23 and the flipping frame 22, so that the lower surface of the side panel of the control cabinet contacts the upper surface of the bottom panel of the control cabinet. At this time, the rollers 24 in the pressing frame 23 contact one side of the side panel of the control cabinet, and the rollers 24 in the flipping frame 22 contact the other side of the control side panel. The number of rollers 24 cooperate to limit the side panel of the control cabinet from tilting in the direction close to or away from the welding robot 4, so that the side panel of the control cabinet can only be vertically placed on the upper surface of the bottom panel of the control cabinet, ensuring that the welding robot 4 vertically welds the two panels. The rollers 24 in the flipping frame 22 and the side of the limiting frame 366 far from the welding robot 4 are located in the same vertical plane. Therefore, when the side panel of the control cabinet is squeezed and cooperated with the number of rollers 24, the sides of the side panel of the control cabinet and the bottom panel of the control cabinet close to the welding robot 4 are located in the same vertical plane. Pass the side panel of the control cabinet through the position between the pressing frame 23 and the flipping frame 22 and vertically place it on the upper surface of the bottom panel of the control cabinet, and make both sides of the side panel of the control cabinet contact the two L-shaped clamping plates 35 respectively, then it can be ensured that the lower end surface of the side panel of the control cabinet coincides with the side of the upper surface of the bottom panel of the control cabinet close to the welding robot 4, so as to facilitate the welding robot 4 to weld and fix the side panel of the control cabinet and the bottom panel of the control cabinet.

[0030] Since the thicknesses of the side panels of the control cabinets of different models are different, in order to enable the side panels of the control cabinets with different thicknesses to be squeezed and cooperated with the number of rollers 24, the following further refines the remaining structure of the vertical plate support mechanism 2. Refer to Figure 2, on the side of the pressing frame 23 away from the flipping frame 22, a first lead screw 25 is fixedly connected. One end of the first lead screw 25 penetrates through the side wall of the positioning frame 21. On the side of the positioning frame 21 away from the flipping frame 22, a nut 26 is rotatably connected. The nut 26 is threadedly connected to the first lead screw 25. After inserting the side panel of the control cabinet from top to bottom between the pressing frame 23 and the flipping frame 22, if the panel cannot contact all the rollers 24 and there is a possibility of tipping over, the nut 26 can be rotated. Through the threaded connection between the nut 26 and the first lead screw 25, the first lead screw 25 drives the pressing frame 23 to horizontally move along the inner wall of the positioning frame 21 towards the direction close to the flipping frame 22, so that the rollers 24 in the pressing frame 23 press and push the side panel of the control cabinet towards the direction close to the flipping frame 22 until all the rollers 24 are in contact with the side wall of the side panel of the control cabinet, then the side panels of the control cabinet with different thicknesses can be limited, and welding and assembly can be carried out for control cabinets of different models.

[0031] After placing the bottom panel of the control cabinet at the predetermined position on the processing table 1 under the limitation of the L-shaped clamping plate 35 and the limiting frame 366, during the process of passing the side panel of the control cabinet through between the pressing frame 23 and the flipping frame 22 and vertically placing it on the upper surface of the bottom panel of the control cabinet, the side panel of the control cabinet will contact one end of the sliding plate 362 located between the two L-shaped clamping plates 35, and after contacting the sliding plate 362, it will push the sliding plate 362 along the outer wall of the guide rod 363 and the inner wall of the through groove 361 towards the direction away from the welding robot 4. The distance between the sliding plate 362 and the end plate 364 is shortened, the spring 365 elastically contracts, and the sliding plate 362 drives the limiting frame 366 to move synchronously until the limiting frame 366 is moved to a position where it does not contact the bottom panel of the control cabinet, so that the welding robot 4 can completely weld the overlapping side edges of the two panels, improving the welding quality.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present invention and are not used to limit the present invention.
