Description

Technical Field

[0001] The present invention relates to the technical field of welding of distribution cabinets, and specifically to a welding system for large distribution cabinets. Background Art

[0002] With the rapid development of the power industry, large distribution cabinets, as key equipment in the power grid system, undertake the core functions of power distribution, control, and protection. Their production scale is constantly expanding, posing higher requirements for the efficiency, precision, and quality stability of the welding process. Traditional welding technologies have been difficult to meet the urgent needs of modern industry for the high-efficiency manufacturing, intelligent upgrading, energy conservation, and environmental protection of large distribution cabinets.

[0003] Since distribution cabinets are generally made by splicing sheet metals, they are characterized by large size and heavy weight. During their welding process, the sheet metal cabinets need to be accurately positioned and suspended for fixation to enable multi-sided welding and process operations. The existing technologies generally pre-drill screw holes in the sheet metal parts on both sides of the distribution cabinet and achieve suspended fixation by rigidly connecting them with bolts to lifting tools or support devices. However, due to the large weight of the distribution cabinet, the bolts will generate concentrated stress on the screw holes and the surrounding sheet metal when bearing the gravity, resulting in deformation of the screw threads of the screw holes, tearing or cracking of the sheet metal, directly affecting the structural strength and sealing performance of the cabinet body. Summary of the Invention

[0014] Preferably, the welding device includes a welding robot provided on the back of the base, and a visual inspection device capable of detecting the position to be welded on the power distribution cabinet is provided at a position close to the welding head on the welding robot.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: 1. In this application, a first clamping mechanism and a second clamping mechanism are provided for firmly supporting the power distribution cabinet. Specifically, the first clamping mechanism includes a first adjusting nut, a second adjusting nut, a first adjusting screw, a second adjusting screw, and a support block. During use, the first adjusting nut and the second adjusting nut can be rotated according to the actual size of the power distribution cabinet to adjust the lengths of the first adjusting screw and the second adjusting screw. Through this adjustment, the support block below can be clamped at the corner below the power distribution cabinet to achieve preliminary fixing and support of the power distribution cabinet. Subsequently, the first clamping mechanism above the power distribution cabinet is rotated so that the support block is also clamped at the corner above the power distribution cabinet, forming double support from top to bottom to ensure the stability of the power distribution cabinet. At the same time, the second clamping mechanism drives the third adjusting screw to rotate by rotating the adjusting wheel, and then the clamping plate is clamped on the side of the power distribution cabinet. This clamping method is not only firm and reliable, but also avoids damage to the sheet metal of the power distribution cabinet caused by the traditional bolt and screw hole fixing method, effectively solving the problem of sheet metal tearing of the power distribution cabinet caused by the traditional bolt and screw hole fixing.

[0016] 2. The design of the first clamping mechanism and the second clamping mechanism in this application fully considers the diversity of the sizes of power distribution cabinets. By adjusting the first adjusting nut, the second adjusting nut, and the adjusting wheel, the effective clamping space of the first clamping mechanism and the second clamping mechanism can be flexibly adjusted to adapt to power distribution cabinets of different specifications and sizes. This design makes the device in this application have stronger versatility and adaptability, and can meet the needs of different users.

[0017] 3. During the actual welding process of the power distribution cabinet, it is often necessary to flip the power distribution cabinet to perform welding operations on each surface. This application is provided with a flipping device. Through the action of the moving mechanism, the clutch head can be sleeved on the input shaft. At this time, the limit pin on the input shaft is in close fit with the limit groove of the clutch head. By rotating the clutch head, the input shaft can be driven to rotate, and then the output shaft rotates synchronously. The rotation of the output shaft drives the clamping assembly to drive the power distribution cabinet to achieve flipping. In addition, the flipping device also adopts a design that combines manual and automatic methods, making the flipping operation of the power distribution cabinet more flexible and convenient, and greatly improving the operation efficiency.

[0018] 4. To facilitate the maintenance and replacement of the clamping assembly, this application is also provided with a quick replacement function.

Detailed implementation manners

[0031] To further understand the features, technical means, and the specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0032] Referring to Figures 1 - 11 As shown, the present invention provides a large-scale power distribution cabinet welding system, including a power distribution cabinet clamping device and a welding device. The power distribution cabinet clamping device includes a base 1 and a conveying skid 2 arranged on the base 1 and capable of adjusting its position. The base 1 further includes an adjusting mechanism capable of driving the conveying skid 2 to adjust its position on the base 1 and a limiting mechanism for limiting the position of the conveying skid 2. The conveying skid 2 includes a flipping device 21 installed on one side of the conveying skid 2 and a support device 22 capable of reciprocating along the length direction of the conveying skid 2. Clamping assemblies 3 capable of clamping the power distribution cabinet are respectively arranged on the flipping device 21 and the support device 22. The clamping assembly 3 includes a connecting plate 31, and a first clamping mechanism 32 capable of clamping along the height direction of the power distribution cabinet and a second clamping mechanism 33 capable of clamping along the width direction of the power distribution cabinet are arranged on the connecting plate 31.

[0033] When welding a large power distribution cabinet is required, after lifting the power distribution cabinet with a crane, according to the size of the power distribution cabinet, move the support device 22. The support device 22 moves along the length direction of the conveying skid 2 to a suitable position. The power distribution cabinet is hoisted between the two clamping components 3. The first clamping mechanism 32 and the second clamping mechanism 33 clamp and fix the power distribution cabinet from the height direction and the width direction of the power distribution cabinet respectively, ensuring that the power distribution cabinet remains stable on the support device 22. The conveying skid 2 is driven by the adjusting mechanism to move on the base 1, transporting the power distribution cabinet near the welding station. During the movement, the limiting mechanism ensures that the conveying skid 2 accurately stops at the designated position. Meanwhile, during the welding process, if different surfaces of the power distribution cabinet need to be welded, the flipping device 21 starts to work, driving the power distribution cabinet to flip, so that the welding device can comprehensively weld all surfaces of the power distribution cabinet.

[0034] The first clamping mechanism 32 is distributed at the four corners of the connecting plate 31 and the first clamping mechanism 32 rotates around the connection point with the connecting plate 31. The first clamping mechanism 32 includes a main body 321, and one end of the main body 321 is provided with a first adjusting screw 322 that can move in the main body 321. The end of the first adjusting screw 322 away from the main body 321 is rotatably connected to a support block 3221 that can be stuck on the edge of the power distribution cabinet. The other end of the main body 321 is provided with a second adjusting screw 323 that can move in the main body 321. The end of the second adjusting screw 323 away from the main body 321 is movably connected to the connecting plate 31.

[0035] The first adjusting screw 322 is arranged at one end of the main body 321 and can move in the main body 321. This movement characteristic enables the length of the first adjusting screw 322 to be adjusted according to actual needs. The end of the first adjusting screw 322 away from the main body 321 is rotatably connected to a support block 3221. The support block 3221 is a component that directly contacts the power distribution cabinet, and its shape and size are designed to be able to be stuck on the edge of the power distribution cabinet. By adjusting the movement of the first adjusting screw 322 in the main body 321, the position of the support block 3221 can be changed, so as to adapt to the positions of the edges of power distribution cabinets of different sizes, ensure that the support block 3221 can closely fit on the edges of the power distribution cabinet, and provide stable support and clamping force for the power distribution cabinet. The second adjusting screw 323 is located at the other end of the main body 321 and can also move in the main body 321. The end of the second adjusting screw 323 away from the main body 321 is movably connected to the connecting plate 31. This movable connection method enables the second adjusting screw 323 to adjust its position within a certain range, cooperate with the first adjusting screw 322, and jointly realize the adjustment of the overall position and posture of the first clamping mechanism 32. By adjusting the second adjusting screw 323, the clamping effect of the first clamping mechanism 32 on the power distribution cabinet can be further optimized, ensuring that the power distribution cabinet maintains a stable position during the welding process and avoiding affecting the welding quality due to shaking.

[0036] One end of the main body 321 close to the first adjusting screw 322 is rotatably provided with a first adjusting nut 3211. The first adjusting nut 3211 is threadedly connected to the first adjusting screw 322. One end of the main body 321 close to the second adjusting screw 323 is rotatably connected to a second adjusting nut 3212. The second adjusting nut 3212 is threadedly connected to the second adjusting screw 323. When the first adjusting nut 3211 rotates, the first adjusting screw 322 can telescopically move in the main body 321. When the second adjusting nut 3212 rotates, the second adjusting screw 323 can telescopically move in the main body 321. The cross-section of the support block 3221 is in an "L" shape.

[0037] At one end of the main body 321 close to the first adjusting screw 322, a first adjusting nut 3211 is rotatably provided. The first adjusting nut 3211 is threadedly connected to the first adjusting screw 322. This threaded connection has the characteristics of self-locking and precise adjustment. When the operator rotates the first adjusting nut 3211, due to the interaction of the threads, the first adjusting screw 322 will telescopically move in the main body 321. Through this telescopic movement, the position of the support block 3221 can be precisely adjusted to meet the position requirements of the corners of distribution cabinets of different sizes. One end of the main body 321 close to the second adjusting screw 323 is rotatably connected to a second adjusting nut 3212. The second adjusting nut 3212 is also threadedly connected to the second adjusting screw 323. When the second adjusting nut 3212 is rotated, the second adjusting screw 323 will also telescopically move in the main body 321. The telescopic movement of the second adjusting screw 323 cooperates with the telescopic movement of the first adjusting screw 322 to jointly adjust the overall position and posture of the first clamping mechanism 32, ensuring stable and reliable clamping of the distribution cabinet. The cross-section of the support block 3221 is in an "L" shape. This "L" shape design has unique advantages. It can better fit the shape of the corners of the distribution cabinet. The second clamping mechanism 33 includes clamping plates 331 arranged on the front and rear sides of the connecting plate 31 and capable of clamping on the power distribution cabinet. The cross-section of the clamping plate 331 is in an "L" shape. The main function of the clamping plate 331 is to directly clamp on the power distribution cabinet to achieve the fixation of the power distribution cabinet in the width direction. The cross-section of the clamping plate 331 is in an "L" shape, and this special shape design has significant advantages. The "L" shape structure can increase the contact area between the clamping plate 331 and the power distribution cabinet, providing a more stable clamping force. A sliding groove 311 is opened along the moving direction of the clamping plate 331 on the inner side of the connecting plate 31, and a guide rail 3311 capable of slidingly cooperating with the sliding groove 311 is also provided on the clamping plate 331. The cooperation of the sliding groove 311 and the guide rail 3311 plays a key guiding role. The sliding groove 311 and the guide rail 3311 can guide the clamping plate 331 to move smoothly along a predetermined direction, avoiding the deviation or shaking of the clamping plate 331 during the movement. A third adjusting screw 332 capable of driving the clamping plate 331 to move is arranged on the connecting plate 31 along the moving direction of the clamping plate 331 through threads. The third adjusting screw 332 is movably connected to the clamping plate 331, and an adjusting wheel 3321 capable of rotating the third adjusting screw 332 is also provided on the third adjusting screw 332. The rotation of the third adjusting screw 332 can be converted into a linear motion of the clamping plate 331, and due to the self-locking characteristic of the threads, the clamping plate 331 can be kept stable after being adjusted to a suitable position, preventing it from moving by itself.

[0038] When it is necessary to clamp the power distribution cabinet, the operator rotates the adjusting wheel 3321, and the adjusting wheel 3321 drives the third adjusting screw 332 to rotate. Since the third adjusting screw 332 is threadedly connected to the connecting plate 31, under the action of the threads, the rotation of the third adjusting screw 332 will push the clamping plate 331 to move along the sliding groove 311. The guide rail 3311 on the clamping plate 331 slides in the sliding groove 311 to ensure the smoothness and accuracy of the movement of the clamping plate 331. As the clamping plate 331 moves, its "L" shape structure gradually approaches the power distribution cabinet and finally clamps on the power distribution cabinet, achieving stable clamping of the power distribution cabinet in the width direction. During the welding process, if it is necessary to adjust the clamping force or deal with power distribution cabinets of different sizes, the operator only needs to rotate the adjusting wheel 3321 again to change the position of the clamping plate 331, thereby adjusting the clamping effect.

[0039] The supporting device 22 includes a second supporting column 221 capable of moving along the length direction of the conveying sled 2. A clamp 222 for fixing the second supporting column 221 on the conveying sled 2 is further provided on the second supporting column 221. The main function of the clamp 222 is to fix the second supporting column 221 on the conveying sled 2. After the second supporting column 221 moves to a proper position, by operating the clamp 222, it can tightly press the conveying sled 2, thereby firmly fixing the second supporting column 221 at the current position. A second mounting plate 224 capable of being fixed to one set of clamping components 3 is provided at the top of the second supporting column 221. The second mounting plate 224 is fixed to the side surface of the connecting plate 31. A second supporting shaft 2241 is further connected to the second mounting plate 224. Two sets of guide wheels 223 are provided at the top of the second supporting column 221. The second supporting shaft 2241 can be placed on the two sets of guide wheels 223. The design of the guide wheels 223 plays an important role. When the second supporting shaft 2241 rotates, the guide wheels 223 can provide stable support and guidance for the second supporting shaft 2241, reduce the friction between the second supporting shaft 2241 and the top of the second supporting column 221, and make the rotation of the second supporting shaft 2241 smoother and more stable.

[0040] During actual use, according to the size of the power distribution cabinet, the distance between the second supporting column 221 and the flipping device 21 is adjusted. After the second supporting column 221 moves to a proper position, operate the clamp 222 to fix the second supporting column 221 on the conveying sled 2. At this time, the second mounting plate 224 supports the clamping components 3 through connection with the clamping components 3. When the power distribution cabinet is flipped, the clamping components 3 will rotate synchronously, and the second mounting plate 224 and the second supporting shaft 2241 will rotate. Under the support and guidance of the two sets of guide wheels 223, the second supporting shaft 2241 can rotate smoothly, ensuring the stable rotation of the power distribution cabinet.

[0041] The flipping device 21 includes a first support column 211 fixed to the conveying skid 2. And at the top of the first support column 211, there is a worm and worm gear reducer 212 capable of driving the power distribution cabinet to flip. The worm and worm gear reducer 212 is the core driving component for the flipping device 21 to achieve the flipping function of the power distribution cabinet. The worm and worm gear reducer 212 has a self-locking property and can keep the position of the output shaft 213 unchanged after stopping rotation, so as to ensure that the power distribution cabinet can stay stably after flipping to the specified angle and will not rotate by itself due to external forces. At the output end of the worm and worm gear reducer 212, there is an output shaft 213, and a support member 214 is connected to the output shaft 213. The flipping device 21 further includes a first mounting plate 216 that can be fixed to one side of the connecting plate 31 in the clamping assembly 3. And on one side of the first mounting plate 216, there is also a first support shaft 2161 that can be stuck in the support member 214. The flipping device 21 is also provided with a locking assembly 215 that can fix the first support shaft 2161 on the support member 214. The locking assembly 215 can ensure the firm and reliable connection between the first support shaft 2161 and the support member 214 and prevent the first support shaft 2161 from disengaging from the support member 214. The input end of the worm and worm gear reducer 212 is connected with a handwheel 2121 and an input shaft 2122.

[0042] When it is necessary to flip the power distribution cabinet, the operator first ensures that the first support shaft 2161 has been stuck in the support member 214 and uses the locking assembly 215 to fix it firmly. Then, the operator rotates the handwheel 2121, and the power is transmitted to the inside of the worm and worm gear reducer 212. After the worm and worm gear reducer 212 decelerates and increases the torque of the input power, the power is output through the output shaft 213 to drive the support member 214 to rotate. Since the first support shaft 2161 is fixed in the support member 214, and the first mounting plate 216 is connected to the first support shaft 2161, and at the same time the first mounting plate 216 is fixed to one side of the connecting plate 31 of the clamping assembly 3, the rotation of the support member 214 will drive the first mounting plate 216, the clamping assembly 3 and the clamped power distribution cabinet to flip together. When the power distribution cabinet flips to the required angle, stop rotating the handwheel 2121. Due to the self-locking property of the worm and worm gear reducer 212, the power distribution cabinet can stay stably at this angle for subsequent welding and other operations.

[0043] On the back of the flipping device 21, there is also a positioner 4 capable of driving the power distribution cabinet to flip. There is also a limit pin on the input shaft 2122. The positioner 4 includes a clutch head 43 that can be sleeved on the input shaft 2122. And on the clutch head 43, there is also a limit groove capable of accommodating the limit pin. The positioner 4 also includes a rotation driving member 44 for driving the clutch head 43 to rotate. The positioner 4 also includes a moving seat 42 that can reciprocate along the direction of the worm and worm gear reducer 212 and is used to support the rotation driving member 44. The positioner 4 also includes a moving mechanism 41 for driving the moving seat 42 to reciprocate.

[0044] When it is necessary to use the positioner 4 to drive the power distribution cabinet to flip, the moving mechanism 41 is activated, driving the moving seat 42 to move along the direction of the worm and worm gear reducer 212, so that the rotary driving member 44 and the clutch head 43 approach the worm and worm gear reducer 212. As the moving seat 42 moves, the clutch head 43 gradually sleeves on the input shaft 2122. At the same time, the limit pin on the input shaft 2122 enters the limit groove on the clutch head 43, ensuring that the clutch head 43 is accurately aligned with the input shaft 2122 and can rotate synchronously. The rotary driving member 44 is activated to drive the clutch head 43 to rotate. The clutch head 43 drives the input shaft 2122 to rotate through the cooperation of the limit pin and the limit groove. The input shaft 2122 transmits the power to the inside of the worm and worm gear reducer 212. After deceleration and torque increase processing, the support member 214, the first mounting plate 216, the clamping assembly 3 and the clamped power distribution cabinet are driven to flip together through the output shaft 213. When it is not necessary to use the positioner 4 to drive, the rotary driving member 44 stops working. The moving mechanism 41 is activated in the reverse direction, driving the moving seat 42 to move in the opposite direction, so that the rotary driving member 44 and the clutch head 43 are away from the worm and worm gear reducer 212, and the clutch head 43 disengages from the input shaft 2122. At this time, the manual operating handwheel 2121 can be restored to drive the power distribution cabinet to flip. The welding device includes a welding robot 5 arranged on the back of the setting base 1. A visual inspection device 51 capable of detecting the position to be welded on the power distribution cabinet is arranged at a position close to the welding head on the welding robot 5.

[0045] The welding robot 5 is the core execution component of the welding device. It can accurately control the movement of the welding head according to the preset program and path, realizing the automatic welding of the power distribution cabinet. Compared with traditional manual welding, the welding robot 5 has the advantages of high welding accuracy, stable welding quality, high production efficiency, good repeatability, etc., which can greatly improve the welding quality and production efficiency of the power distribution cabinet, and reduce the labor cost and labor intensity.

[0046] During the welding operation process, the welding robot 5 first moves to the approximate welding area according to the preset program. At this time, the visual inspection device 51 starts to work, accurately detecting the position to be welded, and transmitting the detected position information to the control system of the welding robot 5. The control system fine-tunes the movement trajectory of the welding robot 5 according to this information, so that the welding head accurately aligns with the position to be welded. Then, the welding robot 5 performs the welding operation according to the predetermined welding parameters.

[0047] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
