Description

Technical Field

[0001] The present invention relates to the technical field of switchgear welding, and particularly to a welding device for processing the door panels of MNS switchgear. Background Art

[0002] The MNS switchgear is a low-voltage switchgear widely used in the power system, mainly used for distributing electric energy and protecting the circuit from faults such as overload and short circuit. The outer frame of the MNS switchgear is usually made of cold-rolled steel plate, and the surface is treated with anti-corrosion to ensure good durability. During the processing of the door panel of the MNS switchgear, stiffeners need to be installed to improve the strength of the door panel, and the stiffeners are usually fixed to the door panel in the form of welding.

[0003] The stiffeners on the MNS switchgear are composed of two long stiffeners and two short stiffeners. The two long stiffeners and two short stiffeners need to form a rectangular shape on the door panel. In order to make the welding of the two long stiffeners and two short stiffeners on the door panel more regular, during the welding process of the stiffeners, the existing method of positioning the stiffeners is to first weld the two long stiffeners and two short stiffeners into a rectangular shape, then use a clamping device to clamp and fix the welded long stiffeners and short stiffeners on the door panel, and finally weld the stiffener structure formed by the long stiffeners and short stiffeners on the door panel.

[0004] The welding method of first welding the two long stiffeners and two short stiffeners into a rectangular shape and then welding the welded long stiffeners and short stiffeners on the door panel has the problems of many operation procedures and long welding time; and when the stiffener formed by the long stiffeners and short stiffeners is fixed on the door panel, it usually requires manual operation of the clamping device to position the stiffener, which easily results in low positioning accuracy of the stiffener on the door panel, leading to the uneven positions of the stiffeners on each door panel produced, making the product have obvious defects as a whole. Therefore, we propose a welding device for processing the door panels of MNS switchgear. Summary of the Invention

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0024] Please refer to Figure 1 - Figure 10 As shown, a welding device for processing the door panel of an MNS switchgear cabinet includes a loading assembly 3 for conveying the door panel main body 1 and the reinforcing rib 2, a welding assembly 4 provided on one side of the loading assembly 3, a retention assembly 5 for positioning the door panel main body 1 and the reinforcing rib 2 provided on the side of the loading assembly 3, a lifting table 19 provided above the loading assembly 3, and a position adjustment assembly 6 for adjusting the positions of the long rib and the short rib in the reinforcing rib 2 respectively provided at the bottom of the lifting table 19; Based on this device, it is used to weld the reinforcing rib 2 to the door panel body 1, and the reinforcing rib 2 includes two long ribs and two short ribs, and the length of the long rib is longer than that of the short rib. When in use, the door panel body 1 is placed on one side of the feeding component 3, and the reinforcing rib 2 is placed on the upper inner side of the door panel body 1. The long rib and the short rib in the reinforcing rib 2 are placed in the door panel body 1 in an approximately rectangular shape, and there are gaps between the long rib and the side wall of the door panel body 1 and between the short rib and the side wall of the door panel body 1. Then the feeding component 3 conveys the door panel body 1, and when it is conveyed to the target position, the retaining component 5 first clamps the four corners of the door panel body 1 to position the door panel body 1, and then the positioning component 6 is used to adjust the position of the long rib and the short rib in the door panel body 1, so that the long rib and the short rib form a mutually perpendicular structure, and finally the retaining component 5 resists the long rib and the short rib, and cooperates with the positioning component 6, so that the long rib and the short rib form a regular rectangular structure, and the retaining component 5 forms a final clamping of the regular long rib and the short rib. After fixing the positions of the long and short ribs, use the welding assembly 4 to weld the ends of the long and short ribs that abut each other and the positions where their ends connect with the door panel body 1, so that the long and short ribs are welded together and welded to the inner side of the door panel body 1, and spot weld the positions where the inner side of the long ribs and the door panel body 1 fit together, and spot weld the positions where the inner side of the short ribs and the door panel body 1 fit together. After this spot welding is completed, remove the parts of the adjustment assembly 6 and the fixing assembly 5 that are stuck on the outside of the reinforcement rib 2, and spot weld the positions where the outside of the reinforcement rib 2 and the door panel body 1 fit together again. After spot welding is completed, the reinforcement rib 2 is firmly fixed on the door panel body 1.

[0025] The retaining assembly 5 includes a locking assembly 51 arranged on the side of the feeding assembly 3 and used to lock the corner of the door panel body 1, a first hydraulic rod 52 arranged above the locking assembly 51, and a first L-shaped clamping plate 53 fixedly arranged at the output end of the first hydraulic rod 52. The first L-shaped clamping plate 53 is used to make the ends of the long ribs and the short ribs in the reinforcing rib 2 after the position adjustment by the positioning assembly 6 abut against each other; the locking assembly 51 locks the corner of the door panel body 1 so that the lifting platform 19 is located directly above the door panel body 1. When the positioning assembly 6 adjusts the position of the reinforcing rib 2, it ensures that the reinforcing rib 2 can be adjusted to the target position, thereby improving the welding accuracy of the reinforcing rib 2 in the door panel body 1. The first L-shaped clamping plate 53 clamps the reinforcing rib 2, which is convenient for the final positioning of the long and short ribs, so that the long and short ribs are firmly fixed at the target position in the door panel body 1. The first L-shaped clamping plate 53 clamps the outside of the ends of the long and short ribs in the reinforcing rib 2, so that the welding assembly 4 can conveniently weld the inside of the ends of the long and short ribs, so that the reinforcing rib 2 and the door panel body 1 are initially welded and fixed. After the reinforcing rib 2 is initially welded and fixed, the first L-shaped clamping plate 53 and the positioning assembly 6 are removed, and the reinforcing rib 2 and the outside of the door panel body 1 are spot welded. The reinforcing rib 2 is welded and fixed on the door panel body 1, and the entire process of welding the door panel is completed, and the door panel can be cut.

[0026] The positioning assembly 6 includes an electric cylinder 61 and an electric push rod 64 fixedly arranged on the side of the lifting platform 19, a mounting seat 62 fixedly arranged at the output end of the electric cylinder 61, a first conveyor belt 63 movably arranged at the bottom of the mounting seat 62, a guide seat 65 fixedly arranged at the output end of the electric push rod 64, and a second conveyor belt 66 movably arranged at the bottom of the guide seat 65. The first conveyor belt 63 and the second conveyor belt 66 cooperate to move the reinforcing rib 2. The mounting seat 62 and the guide seat 65 are arranged in parallel and perpendicular to the conveying direction of the electric cylinder 61. Each long rib in the reinforcing rib 2 has two corresponding positioning assemblies 6 for position adjustment, and each short rib has one corresponding positioning assembly 6 for position adjustment.

[0027] Based on this device, the long ribs and short ribs in the reinforcing ribs 2 are placed in the door panel body 1 in an approximately rectangular shape. When the door panel body 1 is transported to the target position by the loading assembly 3 and is clamped by the clamping assembly 51, the loading assembly 3 stops conveying. When adjusting the position of the long ribs and short ribs, the lifting platform 19 first drives the positioning assembly 6 to descend, the electric cylinder 61 pushes the mounting seat 62, so that the first conveyor belt 63 contacts the corresponding inner wall of the long rib / inner wall of the short rib, and the electric push rod 64 pulls the guide seat 65, so that the second conveyor belt 66 contacts the corresponding inner wall of the long rib / inner wall of the short rib, and the first conveyor belt 63 and the second conveyor belt 66 press the long rib / short rib in the middle, so that the long rib / short rib is parallel to the side wall of the adjacent door panel body 1.

[0028] When in use, the first conveyor belt 63 and the second conveyor belt 66 are first rotated to pull the long ribs / short ribs to move inside the door panel body 1, so that the adjacent ends of the long ribs and short ribs are constantly approaching until they are against each other, and then the electric cylinder 61 is used to pull / push the mounting seat 62, and the electric push rod 64 is used to pull / push the guide seat 65, so that the first conveyor belt 63 and the second conveyor belt 66 change the distance between the long ribs / short ribs and the side wall of the door panel body 1, and finally the first hydraulic rod 52 is used to push the first L-shaped card plate 53, so that each first L-shaped card plate 53 is close to the end of the corresponding long ribs and short ribs, and under the resistance of the first L-shaped card plate 53, the long ribs and short ribs form a regular rectangular structure. In the process of adjusting the long ribs and short ribs in the horizontal and vertical positions respectively, the long ribs and short ribs are always parallel to the corresponding side walls of the door panel body 1, so as to prevent the long ribs and short ribs from being deflected in the position adjustment of the long ribs and short ribs.

[0029] After the long ribs and short ribs are spliced ​​into a regular rectangle, the lifting platform 19 moves downward. At this time, the first conveyor belt 63 and the second conveyor belt 66 that clamp the long ribs and short ribs press the corresponding long ribs and short ribs onto the surface of the door panel body 1, so that the long ribs and short ribs are in closer contact with the door panel body 1, making the welding gap smaller and the welding effect better.

[0030] Therefore, when using this device, the long ribs / short ribs are resisted by the first conveyor belt 63 and the second conveyor belt 66, which facilitates making the inner walls of the long ribs / short ribs parallel to the inner wall of the door panel main body 1 facing them. Due to the rotation of the first conveyor belt 63 and the second conveyor belt 66, the long ribs / short ribs can be pulled. And through the pulling / pushing of the mounting seat 62 by the electric cylinder 61 and the pulling / pushing of the guiding seat 65 by the electric push rod 64, the first conveyor belt 63 and the second conveyor belt 66 can change the distance between the long ribs / short ribs and the side wall of the door panel main body 1, enabling the long ribs / short ribs to move both horizontally and vertically within the door panel main body 1, playing a role in precisely adjusting the positions of each long rib and each short rib within the door panel main body 1. When the first hydraulic rod 52 pushes the first L-shaped clamping plate 53, finally, in cooperation, the long ribs and short ribs form a regular rectangular structure, making the reinforcing rib 2 in the target position on the door panel main body 1 and playing a role in precisely positioning the reinforcing rib 2.

[0031] In this device, by placing the long ribs and short ribs in the reinforcing rib 2 on the door panel main body 1 and using the cooperation of the retention assembly 5 and multiple position adjustment assemblies 6, the long ribs and short ribs can be precisely welded in the target position, eliminating the need to first weld and fix the long ribs and short ribs to each other and then weld the welded long ribs and short ribs to the door panel main body 1 to set the reinforcing rib 2. Therefore, by directly welding the long ribs and short ribs on the door panel main body 1, this device saves welding time and processes, playing a time-saving and labor-saving role.

[0032] In this device, the application of multiple position adjustment assemblies 6 plays a role in simultaneously adjusting the positions of the long ribs and short ribs, saving adjustment time and solving the problem that existing welding devices are not convenient for precisely adjusting and positioning the position of the reinforcing rib 2.

[0033] Among them, there are four retention assemblies 5, and the retention assemblies 5 correspond one by one to the four corners of the door panel main body 1. The retention assembly 5 also includes piezoelectric sensors 54. Piezoelectric sensors 54 are respectively and fixedly arranged on both sides of the outer corners of the first L-shaped clamping plate 53. One piezoelectric sensor 54 is used to detect the pressure from one end of the long rib in the reinforcing rib 2, and the other piezoelectric sensor 54 is used to detect the pressure from one end of the short rib in the reinforcing rib 2.

[0034] Based on this device, the piezoelectric sensor 54 determines the positions of the long bars and short bars by detecting the pressure from the long bars and short bars. When the end of a certain long bar / short bar first contacts one of the corresponding first L-shaped clamping plates 53, after the piezoelectric sensor 54 in the first L-shaped clamping plate 53 detects the contact signal, the first conveyor belt 63 and the second conveyor belt 66 corresponding to the long bar / short bar pull the long bar / short bar away, enabling the long bars and short bars to contact the inner wall of the first L-shaped clamping plate 53 simultaneously during continuous adjustment, forming a regular rectangular structure, which is convenient for accurately positioning the long bars and short bars.

[0035] Among them, the feeding assembly 3 includes a conveyor 31 and a mounting frame 32 fixedly arranged on the side of the bracket of the conveyor 31. A connecting frame 17 is fixedly installed on the side of the mounting frame 32. The clamping assembly 51 includes a second hydraulic rod 511 fixedly arranged on one side of the connecting frame 17 and a second L-shaped clamping plate 512 fixedly arranged at the output end of the second hydraulic rod 511. The second hydraulic rod 511 pushes the second L-shaped clamping plate 512 to engage with the corner of the door panel main body 1. A first support rod 8 for supporting the output shaft of the second hydraulic rod 511 is fixedly installed on the upper side of the connecting frame 17.

[0036] Based on this device, the conveyor 31 is used to convey the door panel main body 1, the mounting frame 32 and the connecting frame 17 are used to install and fix the retaining assembly 5. The second hydraulic rod 511 pushes the second L-shaped clamping plate 512 to engage with the corner of the door panel main body 1, which is convenient for clamping and fixing the door panel main body 1.

[0037] Among them, one end of the bottom of the sleeve of the first hydraulic rod 52 is movably connected to the connecting frame 17, the other end of the bottom of the sleeve of the first hydraulic rod 52 is movably provided with a connecting rod 9, the bottom of the connecting rod 9 is movably connected to the output end of the second hydraulic rod 511, and a second support rod 10 for supporting the output shaft of the first hydraulic rod 52 is fixedly installed above the corner of the second L-shaped clamping plate 512.

[0038] Based on this device, after the second hydraulic rod 511 pushes the second L-shaped clamping plate 512 to clamp and fix the door panel main body 1, the connecting rod 9 pulls the first hydraulic rod 52 to rotate downward, making the first hydraulic rod 52 in a horizontal state, just enabling the first L-shaped clamping plate 53 to be inside the door panel main body 1, which is convenient for the first L-shaped clamping plate 53 to adjust the positions of the long bars and short bars. Using the second hydraulic rod 511 to pull the first hydraulic rod 52 optimizes the structure of the device, enabling the first hydraulic rod 52 to be driven without additional power and making the adjustment of the first hydraulic rod 52 more convenient.

[0039] Among them, the position adjustment component 6 further includes a power component 67 for respectively driving the first conveyor belt 63 and the second conveyor belt 66. The power component 67 is provided on both the mounting seat 62 and the guiding seat 65. The power component 67 includes a rotating wheel 671, a pressing block 672 fixedly installed on the side of the rotating wheel 671, and a driving motor 673. Rotating wheels 671 are movably installed at both ends of the mounting seat 62 and both ends of the guiding seat 65. Driving motors 673 for driving the rotating wheels 671 to rotate are fixedly installed at the ends of the mounting seat 62 and the guiding seat 65. The first conveyor belt 63 is wound around the outside of the two rotating wheels 671 on the mounting seat 62, and the second conveyor belt 66 is wound around the outside of the two rotating wheels 671 on the guiding seat 65. The pressing block 672 is used to press the reinforcing rib 2 against the surface of the door panel main body 1.

[0040] Based on this device, the rotating wheel 671 on the mounting seat 62 is movably arranged below both ends of the mounting seat 62, the driving motor 673 is fixedly arranged above one end of the mounting seat 62, the rotating wheel 671 on the guiding seat 65 is movably arranged below both ends of the guiding seat 65, and the driving motor 673 is fixedly arranged above one end of the guiding seat 65, which is convenient for driving the first conveyor belt 63 and the second conveyor belt 66 to rotate. After the long rib and the short rib are spliced into a regular rectangle, the lifting platform 19 moves downward. At this time, the pressing block 672 presses the long rib and the short rib against the surface of the door panel main body 1, making the contact between the long rib and the short rib and the door panel main body 1 closer, making the welding gap smaller, and making the welding effect better.

[0041] Among them, anti-slip layers 11 are fixedly arranged on the outsides of both the first conveyor belt 63 and the second conveyor belt 66.

[0042] Based on this device, the anti-slip layer 11 is provided to enhance the anti-slip property between the first conveyor belt 63 and the second conveyor belt 66 and the long rib / short rib, and avoid slipping problems when adjusting the position of the long rib / short rib.

[0043] Among them, anti-off belts 12 are integrally arranged in the middle of the inner sides of both the first conveyor belt 63 and the second conveyor belt 66. Ring grooves 13 adapted to the anti-off belts 12 are opened in the middle of the side surfaces of each rotating wheel 671. Blocks 14 are fixedly arranged on the bottom sides of the mounting seat 62 and the guiding seat 65. Side grooves 15 are opened on the side surfaces of the blocks 14. The anti-off belts 12 are stuck inside the corresponding ring grooves 13 and side grooves 15.

[0044] Based on this device, the anti-off belt 12 and the ring groove 13 prevent the first conveyor belt 63 and the second conveyor belt 66 from falling off the corresponding rotating wheels 671. The block 14 is provided to resist the first conveyor belt 63 / second conveyor belt 66, and avoid deformation of the first conveyor belt 63 and the second conveyor belt 66 when they are in contact with the long rib / short rib, making it convenient for the first conveyor belt 63 and the second conveyor belt 66 to adjust the position of the long rib / short rib.

[0045] Among them, the lifting platform 19 is of an I-shaped structure, and a positioning frame 16 for supporting the electric cylinder 61 and the electric push rod 64 is fixedly arranged at the bottom of the lifting platform 19.

[0046] Based on this device, the I-shaped lifting platform 19 occupies a small area, which is convenient for the welding assembly 4 to perform the welding operation on the door panel.

[0047] Among them, a lifting assembly 7 is arranged on one side of the feeding assembly 3.
