Description

Technical Field

[0001] The invention relates to the technical field of distribution box production, and in particular to an intelligent welding device for distribution box production. Background Art

[0002] The distribution box plays a vital role in the power system. As the control center of power distribution, it can reasonably distribute power and ensure the stability and reliability of power supply. Various switchgear, measuring instruments, protective electrical appliances and auxiliary equipment are integrated inside the distribution box, making the opening and closing operation of the circuit convenient and intuitive. It is widely used in various environments, including residential areas, commercial areas, industrial areas, transportation facilities, public facilities and infrastructure, etc., to provide a stable power supply for various equipment and facilities. In the production process of the distribution box, in order to ensure that it has good anti-deformation performance, welding operations need to be carried out on the side panels and reinforcement ribs need to be added. During the welding operation, it is necessary to ensure that the edges of the contact surface between the side panel and the reinforcement rib are evenly spot welded. However, the welding equipment currently used still needs to rely on the manual operation of the operator to rotate and adjust the side panel and the reinforcement rib when welding the reinforcement rib to the side panel, so as to implement uniform spot welding on the four sides of the contact surface. However, long hours of work will cause operator fatigue, thus affecting the uniformity of weld point distribution, which will not only reduce the overall anti-deformation effect of the distribution box, but may also increase the operator's workload and aggravate their fatigue, thereby having a potential negative impact on production efficiency and product quality; for this reason, the present invention provides an intelligent welding device for distribution box production.

During the movement of the transmission gear 222, the transmission gear 222 is meshed with the rack 25, so that the transmission gear 222 rotates while moving. The rotating transmission gear 222 drives the threaded rod 221 to rotate, and the threaded rod 221 drives the threaded block 23 to move downward, and the threaded block 23 drives the fixed block 24 to move downward. When the shell 21 pushes the side panel 2 to the center position of the top of the storage plate 14, the fixed block 24 abuts against the top of the side panel 2, and the side panel 2 is fixed on the storage plate 14 by means of two sets of symmetrically arranged fixed blocks 24. Then, the controller 42 is set to turn on the electric push rod 27, and the electric push rod 27 drives the frame 1 28 to move downward, and the frame 1 28 drives the threaded rod 3 291 and the transmission gear 3 292 to move downward. Since the transmission gear 3 292 is meshed and connected with the rack 3 32, the transmission gear 3 292 rotates itself during the downward movement, and the rotating transmission gear 3 292 drives the threaded rod 3 291 to rotate, and the threaded rod 3 291 drives the two symmetrically set groups of threaded blocks 3 30 to move away from each other, and the threaded blocks 30 drive the frame 2 35 to move, and the frame 2 35 drives the slide rod 36 , the slider 37 and the vertical rod 39 move. Since the vertical rod 39 passes through the oblique channel 34, the vertical rod 39 moves along the oblique channel 34 while following the movement of the frame 35. The horizontal plate 40 and the positioning rod 41 move synchronously with the vertical rod 39. This makes the positioning rod 41 move downward and expand to the surroundings, so that the four groups of positioning rods 41 are respectively abutted against the four inner corners of the reinforcing rib 3, so that the reinforcing rib 3 is moved to the center of the top of the side plate 2. At the same time, with the help of the four groups of positioning rods 41 abutting against the reinforcing rib 3, the reinforcing rib 3 is not easily offset in the subsequent welding operation; Subsequently, the controller 42 is set to start the longitudinal linear transmission mechanism 7 to drive the two symmetrically arranged groups of welding electrodes 9 to move towards each other, the upper welding electrode 9 abuts against the top of the reinforcing rib 3, and the lower welding electrode 9 abuts against the bottom of the side plate 2. Current flows between the two symmetrically arranged groups of welding electrodes 9, so that the contact surface between the reinforcing rib 3 and the side plate 2 is locally heated and melted, thereby forming a welding point for fixed connection; in addition, the controller 42 is set to start the transverse linear transmission mechanism 6 to drive the longitudinal linear transmission mechanism 7, the mounting frame 8 and the welding electrode 9 to move equidistantly, thereby achieving a uniform spot welding effect; After the front and rear ends of the side plate 2 and the reinforcing rib 3 are uniformly spot welded, the controller 42 starts the motor 4 to drive the transmission rod 51 to rotate, the transmission rod 51 drives the screw tooth pattern 52 and the worm tooth pattern 53 to rotate, the worm tooth pattern 53 drives the worm wheel 11 to rotate, the worm wheel 11 drives the disc 10 to rotate, the disc 10 drives the column 12 to rotate, the column 12 drives the support column 13 to rotate, and the support column 13 drives the storage plate 14, the side plate 2 and the reinforcing rib 3 to rotate 90 degrees; at the same time, the screw tooth pattern 52 drives the two symmetrically arranged groups of transverse linear transmission mechanisms 6 to approach each other, and the transverse linear transmission mechanism 6 drives the welding electrode 9 to move in the direction of the side plate 2 and the reinforcing rib 3; because the width of the side plate 2 and the reinforcing rib 3 is less than the length, the welding electrode 9 is moved to the position where welding is required by adjusting the welding electrode 9 to move in the direction of the side plate 2 and the reinforcing rib 3; after the adjustment is completed, repeat the above welding operation to obtain a uniform spot welding effect; The present invention aims to optimize the welding process and reduce the workload of the operator. In actual application, the operator only needs to place the side panel 2 and the reinforcing rib 3 on the top of the storage plate 14. The device has an automatic pushing function, which can accurately push the side panel 2 and the reinforcing rib 3 to the center position of the top of the storage plate 14 and automatically fix them to ensure stability during welding. Subsequently, the welding electrode 9 can automatically perform uniform spot welding on the side panel 2 and the reinforcing rib 3. After completing the welding on the front and rear sides, the device accurately rotates the storage plate 14 and adjusts the welding electrode 9 to a suitable position so as to weld the left and right sides of the side panel 2 and the reinforcing rib 3. This reduces the workload of the operator to a certain extent.
