Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinet welding, in particular to a large-scale power distribution cabinet welding system. Background Art

[0002] With the rapid development of the electric power industry, large-scale distribution cabinets, as key equipment in power grid systems, assume core functions of power distribution, control, and protection. The continuous expansion of their production scale places higher demands on the efficiency, precision, and quality stability of welding processes. Traditional welding technology is no longer able to meet the urgent needs of modern industry for efficient manufacturing, intelligent upgrades, energy conservation, and environmental protection of large-scale distribution cabinets.

[0003] Because distribution cabinets are generally made of sheet metal, they are large and heavy. During the welding process, the sheet metal cabinet body needs to be precisely positioned and suspended to facilitate multi-sided welding and process operations. The existing technology generally adopts the method of pre-drilling screw holes in the sheet metal parts on both sides of the distribution cabinet, and achieving suspended fixation by rigidly connecting bolts with hangers or support devices. However, due to the heavy weight of the distribution cabinet, the bolts will generate concentrated stress on the screw holes and surrounding sheet metal when subjected to gravity, resulting in deformation of the screw thread, tearing or cracking of the sheet metal, and directly affecting the structural strength and sealing of the cabinet body. Summary of the Invention

[0015] The beneficial effects of the present invention compared to the prior art are:

[0016] 1. This application provides a first clamping mechanism and a second clamping mechanism for providing stable support for the 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 and second adjusting nuts can be rotated to adjust the lengths of the first and second adjusting screws according to the actual size of the distribution cabinet. Through this adjustment, the lower support block can be clamped into the corners below the distribution cabinet, achieving initial fixation and support of the distribution cabinet. Subsequently, the first clamping mechanism above the distribution cabinet is rotated so that the support block is also clamped into the corners above the distribution cabinet, forming a double upper and lower support to ensure the stability of the distribution cabinet. At the same time, the second clamping mechanism rotates the adjustment wheel, driving the third adjusting screw to rotate, thereby clamping the clamping plate to the edge of the distribution cabinet. This clamping method is not only stable and reliable, but also avoids damage to the distribution cabinet sheet metal caused by traditional bolt and screw hole fixing methods, effectively solving the problem of traditional bolt and screw hole fixing causing the distribution cabinet sheet metal to tear.

[0017] 2. The design of the first and second clamping mechanisms of this application fully considers the diversity of distribution cabinet sizes. By adjusting the first and second adjustment nuts and the adjustment wheel, the effective clamping space of the first and second clamping mechanisms can be flexibly adjusted to accommodate distribution cabinets of varying specifications and sizes. This design makes the device of this application more versatile and adaptable, meeting the needs of diverse users.

[0018] 3. In the actual welding process of the distribution cabinet, it is often necessary to flip the distribution cabinet in order to perform welding operations on each surface. The present application is provided with a flipping device, which can enable the clutch head to be set on the input shaft through the action of the moving mechanism. At this time, the limit pin on the input shaft is closely matched with the limit groove of the clutch head, and the rotation of the clutch head can drive the input shaft to rotate, and then the output shaft can be rotated synchronously. The rotation of the output shaft drives the clamping assembly to drive the distribution cabinet to flip. In addition, the flipping device also adopts a design that combines manual and automatic methods, which makes the flipping operation of the distribution cabinet more flexible and convenient, and greatly improves the operating efficiency.

[0019] 4. To facilitate maintenance and replacement of the clamping assembly, this application also incorporates a quick-change feature. By separating the locking assembly from the support, the first mounting plate can be easily removed, and the second mounting plate can also be removed, allowing for easy replacement of the clamping assembly. This design not only reduces maintenance costs but also improves the reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-11 As shown, the present invention provides a large-scale distribution cabinet welding system, including a distribution cabinet clamping device and a welding device. The distribution cabinet clamping device includes a base 1 and a conveying slide 2 arranged on the base 1 and capable of adjusting its position. The base 1 also includes an adjusting mechanism capable of driving the conveying slide 2 to adjust its position on the base 1 and a limiting mechanism for limiting the conveying slide 2. The conveying slide 2 includes a flipping device 21 installed on one side of the conveying slide 2 and a supporting device 22 capable of reciprocating along the length direction of the conveying slide 2. The flipping device 21 and the supporting device 22 are respectively provided with a clamping assembly 3 that can be used to clamp the distribution cabinet. The clamping assembly 3 includes a connecting plate 31. The connecting plate 31 is provided with a first clamping mechanism 32 capable of clamping along the height direction of the distribution cabinet and a second clamping mechanism 33 capable of clamping along the width direction of the distribution cabinet.

[0034] When a large distribution cabinet needs to be welded, the distribution cabinet is lifted by a crane, and the support device 22 is moved according to the size of the distribution cabinet. The support device 22 is moved to a suitable position along the length direction of the conveying slide 2, and the distribution cabinet is hoisted between the two clamping assemblies 3. The first clamping mechanism 32 and the second clamping mechanism 33 clamp and fix the distribution cabinet from the height direction and the width direction of the distribution cabinet respectively to ensure that the distribution cabinet remains stable on the support device 22. The conveying slide 2 is driven to move on the base 1 by the adjustment mechanism to transport the distribution cabinet to the vicinity of the welding station. During the movement, the limiting mechanism ensures that the conveying slide 2 stops accurately at the specified position. At the same time, during the welding process, if it is necessary to weld different sides of the distribution cabinet, the flipping device 21 starts to work, driving the distribution cabinet to flip, so that the welding device can fully weld all sides of the distribution cabinet.

[0035] The first clamping mechanisms 32 are located at the four corners of the connecting plate 31 and rotate about their connection points with the connecting plate 31. The first clamping mechanism 32 includes a main body 321, one end of which is provided with a first adjustment screw 322 that can move within the main body 321. The end of the first adjustment screw 322, away from the main body 321, is rotatably connected to a support block 3221 that can be clamped onto the corners of the power distribution cabinet. The other end of the main body 321 is provided with a second adjustment screw 323 that can move within the main body 321. The end of the second adjustment screw 323, away from the main body 321, is movably connected to the connecting plate 31.

[0036] 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 allows 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 the support block 3221. The support block 3221 is a component that directly contacts the distribution cabinet, and its shape and size are designed to be able to be stuck at the corners of the 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 to adapt to the position of the corners of distribution cabinets of different sizes, ensuring that the support block 3221 can fit tightly on the corners of the distribution cabinet, providing stable support and clamping force for the 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 flexible connection allows the second adjustment screw 323 to be adjusted within a certain range, cooperating with the first adjustment screw 322 to adjust the overall position and posture of the first clamping mechanism 32. By adjusting the second adjustment 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 welding and preventing shaking that affects welding quality.

[0037] A first adjusting nut 3211 is rotatably mounted on one end of the main body 321 near the first adjusting screw 322. The first adjusting nut 3211 is threadedly connected to the first adjusting screw 322. A second adjusting nut 3212 is rotatably mounted on one end of the main body 321 near the second adjusting screw 323. 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 be extended or retracted within the main body 321. When the second adjusting nut 3212 rotates, the second adjusting screw 323 can be extended or retracted within the main body 321. The support block 3221 has an L-shaped cross-section.

[0038] A first adjusting nut 3211 is rotatably mounted on the end of the main body 321 near the first adjusting screw 322. The first adjusting nut 3211 and the first adjusting screw 322 are threadedly connected, a self-locking and precise adjustment feature. When the operator rotates the first adjusting nut 3211, the interaction of the threads causes the first adjusting screw 322 to extend and retract within the main body 321. This retracting motion allows precise adjustment of the position of the support block 3221 to accommodate the angular positioning requirements of distribution cabinets of varying sizes. A second adjusting nut 3212 is rotatably mounted on the end of the main body 321 near the second adjusting screw 323. This second adjusting nut 3212 is also threadedly connected to the second adjusting screw 323. Rotating the second adjusting nut 3212 causes the second adjusting screw 323 to extend and retract within the main body 321. The extension and retraction of the second adjusting screw 323 coordinates with the extension and retraction of the first adjusting screw 322 to 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 "L" shaped. This "L" shaped design has unique advantages, it can better fit the angular shape of the distribution cabinet.

[0039] The second clamping mechanism 33 includes a clamping plate 331 that is arranged on the front and rear sides of the connecting plate 31 and can be clamped on the distribution cabinet, and the cross-section of the clamping plate 331 is "L"-shaped. The main function of the clamping plate 331 is to clamp directly on the distribution cabinet to fix the distribution cabinet in the width direction. The cross-section of the clamping plate 331 is "L"-shaped. This special shape design has significant advantages. The "L"-shaped structure can increase the contact area between the clamping plate 331 and the distribution cabinet, providing a more stable clamping force. A slide groove 311 is provided on the inner side of the connecting plate 31 along the moving direction of the clamping plate 331. The clamping plate 331 is also provided with a guide rail 3311 that can slide with the slide groove 311. The cooperation between the slide groove 311 and the guide rail 3311 plays a key guiding role. The slide groove 311 and the guide rail 3311 can guide the clamping plate 331 to move smoothly along the predetermined direction to prevent the clamping plate 331 from offsetting or shaking during movement. The third adjusting screw 332 is movably connected to the clamping plate 331, and the third adjusting screw 332 is further provided with an adjusting wheel 3321 which can rotate 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 characteristics of the thread, the clamping plate 331 can be kept stable after being adjusted to a suitable position to prevent it from moving on its own.

[0040] When the distribution cabinet needs to be clamped, the operator turns the adjusting wheel 3321, and the adjusting wheel 3321 drives the third adjusting screw 332 to rotate. Since the third adjusting screw 332 is connected to the connecting plate 31 by a thread, under the action of the thread, the rotation of the third adjusting screw 332 will push the clamping plate 331 to move along the slide 311. The guide rail 3311 on the clamping plate 331 slides in the slide 311 to ensure the smoothness and accuracy of the movement of the clamping plate 331. As the clamping plate 331 moves, its "L"-shaped structure gradually approaches the distribution cabinet and is finally clamped on the distribution cabinet, achieving stable clamping of the distribution cabinet in the width direction. During the welding process, if it is necessary to adjust the clamping force or deal with distribution cabinets of different sizes, the operator only needs to turn the adjusting wheel 3321 again to change the position of the clamping plate 331, thereby adjusting the clamping effect.

[0041] The supporting device 22 includes a second support column 221 that can move along the length direction of the conveying slide 2, and the second support column 221 is also provided with a clamp 222 that can fix the second support column 221 on the conveying slide 2. The main function of the clamp 222 is to fix the second support column 221 on the conveying slide 2. When the second support column 221 moves to the appropriate position, the pressure clamp 222 can be operated to tightly press the conveying slide 2, thereby firmly fixing the second support column 221 in the current position. A second mounting plate 224 is provided on the top of the second support column 221, which can be fixed to one of the groups of clamping assemblies 3, and the second mounting plate 224 is fixed to the side of the connecting plate 31, and the second mounting plate 224 is also connected to the second support shaft 2241. Two groups of guide wheels 223 are provided on the top of the second support column 221, and the second support shaft 2241 can be placed on the two groups of guide wheels 223. The design of the guide wheel 223 plays an important role. The guide wheel 223 can provide stable support and guidance for the second support shaft 2241 when the second support shaft 2241 rotates, reducing the friction between the second support shaft 2241 and the top of the second support column 221, so that the rotation of the second support shaft 2241 is more stable and smooth.

[0042] During actual use, the distance between the second support column 221 and the flipping device 21 is adjusted according to the size of the distribution cabinet. After the second support column 221 is moved to the appropriate position, the clamp 222 is operated to fix the second support column 221 on the conveying slide 2. At this time, the second mounting plate 224 supports the clamping assembly 3 by connecting with the clamping assembly 3. When the distribution cabinet is flipped, the clamping assembly 3 will rotate synchronously, and the second mounting plate 224 and the second support shaft 2241 will rotate. Under the support and guidance of the two sets of guide wheels 223, the second support shaft 2241 can rotate smoothly, ensuring the stable rotation of the distribution cabinet.

[0043] The tilting device 21 includes a first support column 211 fixed to the conveyor sled 2. A worm gear reducer 212 is mounted on top of the first support column 211, which drives the cabinet to flip. The worm gear reducer 212 is the core driving component of the tilting device 21, enabling the cabinet to flip. The worm gear reducer 212 has a self-locking feature, maintaining the position of the output shaft 213 after stopping rotation. This ensures that the cabinet remains stable after flipping to the specified angle and is not subject to spontaneous rotation due to external forces. An output shaft 213 is provided at the output end of the worm gear reducer 212, and a support member 214 is connected to the output shaft 213. The flipping device 21 also includes a first mounting plate 216 that can be fixed on one side of the connecting plate 31 in the clamping assembly 3, and a first support shaft 2161 that can be stuck in the support member 214 is also provided on one side of the first mounting plate 216. 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 that the connection between the first support shaft 2161 and the support member 214 is firm and reliable, and prevent the first support shaft 2161 from escaping from the support member 214. The input end of the worm gear reducer 212 is connected with a handwheel 2121 and an input shaft 2122.

[0044] When the distribution cabinet needs to be flipped, the operator first ensures that the first support shaft 2161 is stuck in the support member 214 and securely fixed with the locking assembly 215. Then, the operator turns the handwheel 2121, and the power is transmitted to the inside of the worm gear reducer 212. After the worm gear reducer 212 decelerates and torque-increases the input power, it outputs the power through the output shaft 213, driving 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 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 cause the first mounting plate 216, the clamping assembly 3, and the clamped distribution cabinet to flip together. When the distribution cabinet is flipped to the desired angle, the handwheel 2121 is stopped. Due to the self-locking characteristics of the worm gear reducer 212, the distribution cabinet can remain stable at this angle for subsequent welding and other operations.

[0045] The back of the flipping device 21 is also provided with a positioner 4 that can drive the distribution cabinet to flip, and a limit pin is also provided on the input shaft 2122. The positioner 4 includes a clutch head 43 that can be sleeved on the input shaft 2122, and the clutch head 43 is also provided with a limit groove that can accommodate the limit pin. The positioner 4 also includes a rotating drive member 44 for driving the clutch head 43 to rotate. The positioner 4 also includes a movable seat 42 that can move back and forth in the direction of the worm gear reducer 212 and is used to support the rotating drive member 44. The positioner 4 also includes a moving mechanism 41 for driving the moving seat 42 to move back and forth.

[0046] When the positioner 4 is needed to drive the distribution cabinet to flip, the moving mechanism 41 is activated, driving the moving seat 42 to move along the direction of the worm gear reducer 212, so that the rotating drive member 44 and the clutch head 43 are close to the worm gear reducer 212. As the moving seat 42 moves, the clutch head 43 gradually fits 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 and the input shaft 2122 are accurately aligned and can rotate synchronously. The rotating drive member 44 is activated, driving 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 power to the inside of the worm gear reducer 212. After deceleration and torque increase, the output shaft 213 drives the support member 214, the first mounting plate 216, the clamping assembly 3 and the clamped distribution cabinet to flip together. When the positioner 4 is no longer needed, the rotary drive member 44 stops working. The moving mechanism 41 starts in reverse, driving the moving seat 42 to move in the opposite direction, so that the rotary drive member 44 and the clutch head 43 are away from the worm gear reducer 212, and the clutch head 43 is disengaged from the input shaft 2122. At this time, the manual operation of the hand wheel 2121 can be restored to drive the distribution cabinet to flip.

[0047] The welding device includes a welding robot 5 arranged on the back of the base 1. A visual detection device 51 capable of detecting the position to be welded on the distribution cabinet is provided near the welding head of the welding robot 5.

[0048] The welding robot 5 is the core executive component of the welding system. It precisely controls the movement of the welding head according to a preset program and path, enabling automated welding of the distribution cabinet. Compared to traditional manual welding, the welding robot 5 offers advantages such as high welding precision, stable welding quality, high production efficiency, and good repeatability. This significantly improves the welding quality and production efficiency of distribution cabinets, while reducing labor costs and labor intensity.

[0049] During welding, the welding robot 5 first moves to the approximate welding area according to a pre-set program. At this point, the visual inspection device 51 begins operating, accurately detecting the welding position and transmitting this positional information to the control system of the welding robot 5. Based on this information, the control system fine-tunes the movement trajectory of the welding robot 5, ensuring that the welding head is accurately aligned with the welding position. The welding robot 5 then performs the welding operation according to pre-set welding parameters.

[0050] The above embodiments merely represent one or more embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
