Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinet welding, and in particular to a welding device for processing an MNS switch cabinet door panel. Background Art

[0002] MNS switchgear is a type of low-voltage switchgear widely used in power systems, primarily for distributing electrical energy and protecting circuits from overloads, short circuits, and other faults. The external frame of an MNS switchgear is typically made of cold-rolled steel with an anti-corrosion treatment to ensure excellent durability. During the manufacturing process, the door panels of MNS switchgear require the installation of reinforcing ribs to enhance their strength. These ribs are typically welded to the door panels.

[0003] The reinforcement ribs on the MNS switchgear are composed of two long ribs and two short ribs. The two long ribs and the two short ribs need to form a rectangular shape on the door panel. To ensure a more regular welding of the two long ribs and the two short ribs on the door panel, the existing method for positioning the reinforcement ribs during the reinforcement rib welding process is to first weld the two long ribs and the two short ribs into a rectangular shape, then clamp and fix the welded long and short ribs on the door panel using a clamping device, and finally weld the reinforcement rib structure formed by the long and short ribs to the door panel.

[0004] The previous method, which involves welding two long and two short ribs into a rectangular shape and then attaching them to the door panel, involves multiple steps and is time-consuming. Furthermore, manually positioning the ribs on the door panel often requires manual clamping. This can result in poor positioning accuracy, leading to uneven rib placement on each panel and noticeable overall product defects. To address this issue, we developed a welding device for MNS switchgear door panel processing. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] 1. The present invention utilizes a first conveyor belt and a second conveyor belt to contact the long / short ribs, thereby facilitating the long / short ribs and the inner wall of the door panel body facing each other to be parallel to each other. The rotation of the first and second conveyor belts can pull the long / short ribs, and the pulling / pushing of the mounting seat by the electric cylinder and the pulling / pushing of the guide seat by the electric push rod enable the first and second conveyor belts to change the spacing between the long / short ribs and the side wall of the door panel body, allowing the long / short ribs to move both laterally and longitudinally within the door panel body, thereby precisely adjusting the position of each long rib and each short rib within the door panel body.

[0021] 2. The present invention, through the application of multiple adjustment components, can adjust the positions of long and short reinforcements at the same time, saving adjustment time and solving the problem of the existing welding device that it is inconvenient to accurately adjust and position the reinforcement.

[0022] 3. In the present invention, after the long ribs and short ribs are spliced ​​into a regular rectangle, the lifting platform moves downward. At this time, the first conveyor belt and the second conveyor belt that clamp the long ribs and short ribs press the corresponding long ribs and short ribs onto the surface of the door panel body, so that the long ribs and short ribs are in closer contact with the door panel body, making the welding gap smaller and the welding effect better.

[0023] 4. This invention positions the long and short reinforcement bars within the door panel body, utilizing a retaining assembly and multiple positioning assemblies to precisely weld the long and short bars to the target position. This eliminates the need to first weld the long and short bars together and then weld them to the door panel body. Therefore, by welding the long and short bars directly to the door panel body, this device saves welding time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example

[0038] See also Figure 1 - Figure 10 As shown, a welding device for processing MNS switch cabinet door panels includes a loading assembly 3 for conveying the door panel body 1 and reinforcement ribs 2, a welding assembly 4 arranged on one side of the loading assembly 3, a retaining assembly 5 arranged on the side of the loading assembly 3 for positioning the door panel body 1 and reinforcement ribs 2, a lifting platform 19 arranged above the loading assembly 3, and a positioning assembly 6 arranged at the bottom of the lifting platform 19 for adjusting the position of the long and short ribs in the reinforcement ribs 2 respectively;

[0039] The present device is used to weld reinforcing ribs 2 to a door panel body 1. The reinforcing ribs 2 include two long ribs and two short ribs, with the long ribs being longer than the short ribs. During use, the door panel body 1 is placed on one side of a loading assembly 3, and the reinforcing ribs 2 are placed on the upper inner side of the door panel body 1. The long and short ribs in the reinforcing ribs 2 are arranged in a substantially rectangular shape within the door panel body 1, with gaps between the long ribs and the side walls of the door panel body 1, and between the short ribs and the side walls of the door panel body 1. The loading assembly 3 then conveys the door panel body 1. When it reaches the target position, the retaining assembly 5 first engages the four corners of the door panel body 1 to position the door panel body 1. The adjusting assembly 6 then adjusts the position of the long and short ribs within the door panel body 1 so that they form a mutually perpendicular structure. Finally, the retaining assembly 5 engages the long and short ribs, cooperating with the adjusting assembly 6 to form a regular rectangular structure. The retaining assembly 5 finally engages the regular long and short ribs. 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 and the joint positions of their ends and 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 position where the inner side of the long rib and the door panel body 1 are in contact, and spot weld the position where the inner side of the short rib and the door panel body 1 are in contact. 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 position where the outside of the reinforcement rib 2 and the door panel body 1 are in contact again. After spot welding is completed, the reinforcement rib 2 is firmly fixed on the door panel body 1.

[0040] The retaining assembly 5 includes a locking assembly 51 arranged on the side of the loading 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 rib and the short rib in the reinforcing rib 2 after the position is adjusted by the positioning assembly 6 to offset 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, facilitating the final positioning of the long and short ribs, so that the long and short ribs are firmly fixed in the target position within 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 where they abut against each other, making it convenient for the welding assembly 4 to weld the inside of the ends where the long and short ribs abut against each other, thus forming a preliminary weld fixation between the reinforcing rib 2 and the door panel body 1. 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 outer parts of the reinforcing rib 2 and the door panel body 1 are spot welded. The welding and fixing of the reinforcing rib 2 to the door panel body 1 is completed, which means that the entire welding process of the door panel is completed, and the door panel can then be cut.

[0041] The positioning assembly 6 includes an electric cylinder 61 and an electric push rod 64 fixedly mounted on the side of the lifting platform 19, a mounting base 62 fixedly mounted at the output end of the electric cylinder 61, a first conveyor belt 63 movably mounted at the bottom of the mounting base 62, a guide base 65 fixedly mounted at the output end of the electric push rod 64, and a second conveyor belt 66 movably mounted at the bottom of the guide base 65. The first and second conveyor belts 63 and 66 cooperate to move the reinforcing ribs 2. The mounting base 62 and the guide base 65 are arranged parallel to each other 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.

[0042] Based on this device, the long and short ribs in the reinforcing ribs 2 are placed in a substantially rectangular shape in the door panel body 1. When the door panel body 1 is transported to the target position by the loading assembly 3 and is clamped by the locking assembly 51, the loading assembly 3 stops conveying. When adjusting the position of the long and short ribs, the lifting platform 19 first drives the positioning assembly 6 to descend, the electric cylinder 61 pushes the mounting seat 62, causing the first conveyor belt 63 to contact 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, causing the second conveyor belt 66 to contact the corresponding inner wall of the long rib / inner wall of the short rib. 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 adjacent side wall of the door panel body 1.

[0043] During 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 continuously approached until they abut each other. Then, the electric cylinder 61 pulls / pushes the mounting seat 62, and the electric push rod 64 pulls / pushes 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. Finally, the first hydraulic rod 52 pushes the first L-shaped clamping plate 53, so that each first L-shaped clamping plate 53 is close to the end of the corresponding long ribs and short ribs. Under the resistance of the first L-shaped clamping plate 53, the long ribs and short ribs are formed into a regular rectangular structure. During the process of adjusting the long and short ribs in the horizontal and vertical directions, the long and short ribs are always parallel to the corresponding side wall of the door panel body 1, preventing the long and short ribs from deflecting during the adjustment of their positions.

[0044] 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.

[0045] Therefore, the use of this device allows the long ribs / short ribs to be brought into contact with each other by the first conveyor belt 63 and the second conveyor belt 66, so that the long ribs / short ribs and the inner wall of the door panel body 1 facing each other are parallel to each other. The rotation of the first conveyor belt 63 and the second conveyor belt 66 can pull the long ribs / short ribs, and the pulling / pushing of the mounting seat 62 by the electric cylinder 61 and the pulling / pushing of the guide seat 65 by the electric push rod 64 enable the first conveyor belt 63 and the second conveyor belt 66 to change the spacing between the long ribs / short ribs and the side wall of the door panel body 1, so that the long ribs / short ribs can be moved in the horizontal and vertical directions within the door panel body 1, and the position of each long rib and each short rib within the door panel body 1 is precisely adjusted. When the first hydraulic rod 52 pushes the first L-shaped clamping plate 53, the long ribs and the short ribs are finally coordinated to form a regular rectangular structure, so that the reinforcing rib 2 is at the target position on the door panel body 1, and the reinforcing rib 2 is precisely positioned.

[0046] This device places the long and short ribs of the reinforcing ribs 2 on the door panel body 1 and utilizes the cooperation of the retaining assembly 5 and the plurality of adjusting assemblies 6 to precisely weld the long and short ribs to the target positions. This eliminates the need to first weld the long and short ribs together and then weld the welded long and short ribs to the door panel body 1 to install the reinforcing ribs 2. Therefore, by directly welding the long and short ribs to the door panel body 1, this device saves welding time and processes, thus saving time and effort.

[0047] In this device, the application of multiple adjustment components 6 can adjust the positions of long and short bars at the same time, saving adjustment time and solving the problem of inconvenience in accurate adjustment and positioning of the reinforcing bar 2 in existing welding devices.

[0048] Among them, there are four retaining components 5, and the retaining components 5 correspond to the four corners of the door panel body 1 one by one. The retaining components 5 also include piezoelectric sensors 54. Piezoelectric sensors 54 are fixed on both sides of the corners outside the first L-shaped clamping plate 53. One of the piezoelectric sensors 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.

[0049] Based on this device, the piezoelectric sensor 54 determines the position of the long and short ribs by detecting the pressure from the long and short ribs. When the end of a long / short rib first collides with one of the corresponding first L-shaped pallets 53, the piezoelectric sensor 54 in the first L-shaped pallet 53 detects the collision signal, and then the long / short ribs are pulled away by the first conveyor belt 63 and the second conveyor belt 66 corresponding to the long / short ribs, so that the long and short ribs can simultaneously collide with the inner wall of the first L-shaped pallet 53 during the continuous adjustment process, forming a regular rectangular structure, which is convenient for precise positioning of the long and short ribs.

[0050] Among them, the loading component 3 includes a conveyor 31, 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, and the clamping component 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 and the corner of the door panel body 1 to engage, and a first support rod 8 supporting the output shaft of the second hydraulic rod 511 is fixedly installed on the upper side of the connecting frame 17.

[0051] Based on this device, the conveyor 31 is used to transport the door panel body 1, the mounting frame 32 and the connecting frame 17 are used to install and fix the retaining assembly 5, and the second hydraulic rod 511 pushes the second L-shaped clamping plate 512 to engage the second L-shaped clamping plate 512 with the corner of the door panel body 1, thereby facilitating the clamping and fixing of the door panel body 1.

[0052] Among them, one end of the bottom of the sleeve of the first hydraulic rod 52 is movably connected to the connecting frame 17, and the other end of the bottom of the sleeve of the first hydraulic rod 52 is movably provided with a connecting rod 9, and 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.

[0053] In this device, after the second hydraulic rod 511 pushes the second L-shaped clamping plate 512 to engage and secure the door panel body 1, the connecting rod 9 pulls the first hydraulic rod 52 downward, causing the first hydraulic rod 52 to be horizontal, properly positioning the first L-shaped clamping plate 53 within the door panel body 1, facilitating the first L-shaped clamping plate 53 to adjust the position of the long and short ribs. Using the second hydraulic rod 511 to pull the first hydraulic rod 52 optimizes the device structure, eliminating the need for additional power to drive the first hydraulic rod 52 and making adjustment of the first hydraulic rod 52 more convenient.

[0054] Among them, the positioning assembly 6 also includes a power assembly 67 for respectively transmitting the first conveyor belt 63 and the second conveyor belt 66. The power assembly 67 is provided on the mounting seat 62 and the guide seat 65. The power assembly 67 includes a rotating wheel 671, a pressure block 672 fixedly installed on the side of the rotating wheel 671, and a driving motor 673. The rotating wheels 671 are movably installed at both ends of the mounting seat 62 and the guide seat 65. The ends of the mounting seat 62 and the guide seat 65 are fixedly installed with a driving motor 673 that drives the rotating wheels 671 to rotate. 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 guide seat 65. The pressure block 672 is used to press the reinforcing rib 2 on the surface of the door panel body 1.

[0055] Based on this device, the rotating wheels 671 on the mounting seat 62 are movably disposed below both ends of the mounting seat 62, and the drive motor 673 is fixedly disposed above one end of the mounting seat 62. The rotating wheels 671 on the guide seat 65 are movably disposed below both ends of the guide seat 65, and the drive motor 673 is fixedly disposed above one end of the guide seat 65, thereby driving the first conveyor belt 63 and the second conveyor belt 66 to rotate. After the long and short ribs are spliced ​​into a regular rectangle, the lifting platform 19 moves downward, and the pressing block 672 presses the long and short ribs against the surface of the door panel body 1, thereby ensuring closer contact between the long and short ribs and the door panel body 1, reducing the welding gap and achieving a better welding effect.

[0056] The first conveyor belt 63 and the second conveyor belt 66 are both fixedly provided with an anti-slip layer 11 on their exteriors.

[0057] Based on this device, the anti-slip layer 11 is provided to enhance the anti-slip properties between the first conveyor belt 63 and the second conveyor belt 66 and the long ribs / short ribs, thereby avoiding slipping when adjusting the positions of the long ribs / short ribs.

[0058] Among them, the first conveyor belt 63 and the second conveyor belt 66 are both integrally provided with an anti-slip belt 12 in the middle of the inner side, and a ring groove 13 compatible with the anti-slip belt 12 is opened in the middle of the side of each rotating wheel 671, and a stop block 14 is fixedly provided on the bottom side of the mounting seat 62 and the guide seat 65, and a side groove 15 is opened on the side of the stop block 14, and the anti-slip belt 12 is stuck in the corresponding ring groove 13 and the side groove 15.

[0059] Based on this device, the setting of the anti-slip belt 12 and the setting of the annular groove 13 prevent the first conveyor belt 63 and the second conveyor belt 66 from falling off the corresponding rotating wheel 671, and the setting of the stop block 14 is used to resist the first conveyor belt 63 / the second conveyor belt 66 to prevent the first conveyor belt 63 and the second conveyor belt 66 from being deformed when they resist the long ribs / short ribs, so that the first conveyor belt 63 and the second conveyor belt 66 can easily adjust the position of the long ribs / short ribs.

[0060] The lifting platform 19 is an I-shaped structure, and a positioning frame 16 for supporting the electric cylinder 61 and the electric push rod 64 is fixedly provided at the bottom of the lifting platform 19 .

[0061] 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 door panel welding operation.

[0062] Among them, a lifting assembly 7 is provided on one side of the feeding assembly 3, and the lifting assembly 7 includes a lifting frame 71, a third hydraulic assembly 72 fixedly installed on one side above the lifting frame 71, and a limiting shaft 73 movably arranged on both sides of the third hydraulic assembly 72. The bottom output end of the third hydraulic assembly 72 passes through the lifting frame 71 and is fixedly connected to the lifting platform 19. The bottom of the limiting shaft 73 is fixedly connected to the lifting platform 19. The top of the limiting shaft 73 passes through the lifting frame 71. The top of the lifting frame 71 is fixedly installed with a limiting tube 18, and the limiting tube 18 is sleeved on the side of the limiting shaft 73.
