Description

Technical Field

[0001] The utility model relates to the technical field of processing spare parts of electrical cabinets, in particular to an electrical cabinet welding device with a shock-absorbing function. Background Art

[0002] Welding is a process of heating, melting, and then cooling and solidifying metal materials to connect two or more workpieces together. In the processing of electrical cabinets, it is often necessary to weld small long sheet metal parts to form a right-angle structure. This right-angle structure is usually used as the support structure or internal partition of the electrical cabinet to support and fix various electrical components, circuits and accessories, and also plays a role in strengthening the stability of the overall structure. In this process, the welding device is a device used to implement the welding process, which includes a welding power supply, welding electrodes, a welding control system and welding auxiliary equipment. It may also be equipped with welding auxiliary equipment such as welding fixtures and welding trays. However, during the use of the current welding device, the small long sheet metal parts to be assembled and welded are generally placed in two accessory boxes for the staff to take out and form the sheet metal parts of the right-angle structure. This means that the staff need to take out the workpiece and perform preliminary assembly work before each welding operation, which will cause interruptions and pauses in the welding operation and reduce the continuity of the welding operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0018] Please refer to Figures 1-5, an embodiment provided by the present utility model: a welding device for an electrical cabinet with a shock-absorbing function, including a right-angle support frame 1 and a sprocket feeding frame 2 fixed to the bottom of the right-angle support frame 1. A double-sided sprocket conveying structure 3 is installed on the two inner walls of the sprocket feeding frame 2. A number of equally spaced U-shaped storage frames 4 are installed at the movable end of the double-sided sprocket conveying structure 3. The U-shaped storage frame 4 is made of a rubber material component. The rubber U-shaped storage frame 4 can be deformed to adapt to the transfer of the double-sided sprocket conveying structure 3. Two long strip sheet metal parts to be assembled into a right-angle structure sheet metal part can be pre-placed in the U-shaped storage frame 4. The double-sided sprocket conveying structure 3 and the U-shaped storage frame 4 realize the functions of workpiece loading and unloading;

[0019] A servo motor 5 for driving the double-sided sprocket conveying structure 3 to work is installed on one outer wall of the sprocket feeding frame 2;

[0020] A suspended longitudinal arm 6 is fixed to one outer wall of the right-angle support frame 1 close to the sprocket feeding frame 2. A spot welding machine body 7 is slidably installed on one outer wall of the suspended longitudinal arm 6. A lifting unit is arranged on one outer wall of the spot welding machine body 7. The movable end of the lifting unit is installed with a welding head 703. A right-angle long plate 8 is fixed to the top end of the suspended longitudinal arm 6. And a belt moving structure 9 is arranged at the top end of the right-angle long plate 8. The movable end of the belt moving structure 9 is fixedly connected to one outer wall of the spot welding machine body 7. A servo motor 2 for driving the belt moving structure 9 to work is installed on one outer wall of the right-angle long plate 8. A PLC control panel 11 is installed on the other outer wall of the right-angle support frame 1. The output end of the PLC control panel 11 is electrically connected to the input ends of the servo motor 5, the servo motor 2, and the spot welding machine body 7;

[0021] The sprocket feeding frame 2 includes X-axis cross beams 201 fixed to both sides of the bottom of the right-angle support frame 1. A number of columns 202 are equally spaced and fixed to the top ends of the X-axis cross beams 201. A Y-axis longitudinal beam 203 is installed between two columns 202 in the same Y-axis direction. The double-sided sprocket conveying structure 3 includes two main shafts rotatably installed between the two X-axis cross beams 201, and sprockets fixed to both ends of the main shaft surfaces. A chain is installed between two sprockets in the same X-axis direction. The bottom end of the U-shaped storage frame 4 is installed on the two chains;

[0022] During the process of the servo motor 5 driving the double-sided sprocket conveying structure 3 to work, the rotational power of the servo motor 5 is transmitted to the main shaft, and the main shaft drives the sprocket disc to rotate, so that the chain on the sprocket disc circulates. Since both ends of the U-shaped storage frame 4 are respectively installed on the two chains, the chain can stably drive the U-shaped storage frame 4 to move and circulate;

[0023] On both sides of the top end of the Y-axis longitudinal beam 203, chain shock-absorbing strips 204 are fixed. The upper surface of the chain shock-absorbing strip 204 is in contact with the lower surface of the chain. During the chain circulation process, the chain shock-absorbing strip 204 reduces the up-and-down swing of the chain, which can ensure that the U-shaped material storage frame 4 remains stable during transportation, preventing the workpieces from being damaged or displaced due to vibration or shaking.

[0024] After the U-shaped material storage frame 4 and the workpieces move to the lower part of the spot welding machine body 7, the servo motor II 10 and the belt moving structure 9 drive the spot welding machine body 7 to move in the Y-axis direction, that is, the spot welding machine body 7 moves along the extension line direction of the U-shaped material storage frame 4. The lifting unit is a cylinder 701 installed on one side of the top end of the spot welding machine body 7, and a support 702 installed at the bottom end of the piston rod of the cylinder 701. The welding head 703 is fixed on the outer wall of one side of the support 702. The cylinder 701 drives the support 702 and the welding head 703 to move downward. When the welding head 703 contacts the workpiece, high temperature is generated through current transmission, melting the surface of the workpiece to form a welding joint, thereby realizing the continuous welding function.

[0025] When the embodiment of the present application is in use, first, one staff member is located at the PLC control panel 11, and another staff member is located directly in front of the suspended longitudinal arm 6, or one staff member can also operate the device. The staff members pre-place two long sheet metal parts to be assembled into a right-angle structure sheet metal part in the U-shaped storage frame 4. Subsequently, the staff member turns on the first servo motor 5 through the PLC control panel 11 to work. Then, the first servo motor 5 drives the double-sided sprocket conveying structure 3 to act. At this time, the double-sided sprocket conveying structure 3 drives a plurality of U-shaped storage frames 4 to move together. The double-sided sprocket conveying structure 3 and the U-shaped storage frame 4 realize the feeding and discharging functions of the workpiece. When the U-shaped storage frame 4 containing the workpiece is moved by the double-sided sprocket conveying structure 3 to the lower part of the spot welding machine body 7, the feeding work of the first servo motor 5 and the double-sided sprocket conveying structure 3 is stopped through the PLC control panel 11. At this time, the spot welding machine body 7 corresponds to the workpiece to be welded. Then, the staff member arranges the workpiece in this U-shaped storage frame 4 and initially assembles it into a right-angle structure sheet metal part. After the assembly is completed, the second servo motor 10 and the belt moving structure 9 drive the spot welding machine body 7 to move in the Y-axis direction, and the spot welding machine body 7 performs welding operations on the assembled right-angle structure sheet metal part until the welding is completed. At this time, the first servo motor 5 and the double-sided sprocket conveying structure 3 can be controlled through the PLC control panel 11 to work until the next U-shaped storage frame 4 is moved to the lower part of the spot welding machine body 7, and the welding operation is repeated once according to the above steps to achieve continuous and stable welding operations. When the welded right-angle structure sheet metal part moves to the end of the double-sided sprocket conveying structure 3, it is automatically poured out of the U-shaped storage frame 4. When this welding device is in use, there is no step of taking the workpiece from the material box. Workers no longer need to spend time taking and transporting the workpiece, but can directly place the workpiece required for welding in the U-shaped storage frame 4, and the double-sided sprocket conveying structure 3 automatically sends it to the spot welding machine body 7 for welding. It reduces the pauses and interruptions in the welding process, maintains the stable operation of the production line, and improves the efficiency of the welding operation.
