Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular to a switch cabinet arc welding device capable of multi-station switching and a processing method. Background Art

[0002] Welding device refers to equipment or tools used for welding operations, including welding machines, welding guns, welding electrodes and welding fixtures. The main function of the welding device is to connect two or more metal or non-metal materials together to form a whole by heating, pressurizing or both. The welding device is widely used. Arc welding device is used in the production process of switch cabinets. It uses the high temperature of the arc to melt the weldment and welding materials to achieve welding.

[0003] At present, the existing welding device does not have a multi-station switching function during use. If the welding device only has one welding station, in order to increase the welding efficiency, the heat generated during the welding process of the switch cabinet will be ignored, causing the temperature of the weld area to rise, and the weld area may be deformed. In addition, the welding device has only one station, which will result in the need to adjust the position of the switch cabinet after adjusting a gap in the switch cabinet so that another position to be welded in the switch cabinet corresponds to the welding device, which wastes a lot of time and further reduces the processing efficiency.

[0004] In view of the above problems, it can be found that it is difficult to avoid the above problems at the same time when using the existing switch cabinet arc welding devices with multi-station switching on the market, and even if they can be solved, they need to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

[0018] A method for processing a switch cabinet arc welding device capable of switching multiple workstations comprises the following steps:

[0019] S1: First, when the device is needed, the arc welding device body is controlled to operate, and the arc welding device body is used to weld the switch cabinet placed on the surface of the rotating plate. When a gap in the switch cabinet below the arc welding device body is welded, the electromagnet can be controlled to be closed. The electromagnet will stop generating magnetic force when it is closed, so the moving frame below the arc welding device body will not be attracted by the magnet. At this time, all electric motors can be controlled to operate. The operation of the electric motor will drive the first gear fixed at its output end to rotate, and three of the first gears are in contact with the guide rail, which will guide the first gear to move along the guide rail, and the other two first gears are in contact with the outer surface of the lifting plate, and the first gears in contact with the surface of the lifting plate will also enter the guide rail under the guidance of the lifting plate. The first gear can be used to drive the movable frame and the rotating plate above to move. It should be understood that the operation time of each electric motor will cause the movable frame and the rotating plate to move a quarter of a circle along the edge of the fixed box. It can be understood that the operation of all electric motors will drive all the switch cabinets to be welded to move along the guide rail. With the operation of the electric motor, the movable frames above the right lifting plate, at the rear of the fixed box and on both sides of the fixed box will move a quarter of a circle, and when the movable frame above the leftmost lifting plate is about to move to the top of the rightmost lifting plate following the electric motor, the movable frame on the left side of the fixed box will also follow the electric motor to move to the left side of the second gear, and at this time the teeth of the second gear are aligned with the left side of the fixed box. The second gear plate in the movable frame on the side is meshing with each other. As the electric motor continues to run, the second gear plate will push the second gear to rotate. The rotation of the second gear will drive the winding drum to wind up the first transmission rope, and pull the first return spring outward through the first circular plate. In addition, the second gear will also drive the limiting cylinder and the rotating cylinder to rotate. The rotation of the rotating cylinder will wrap the rope around the surface of the rotating cylinder, so that the two lifting plates can be pulled downward by the rope. When the limiting opening opened on the surface of the limiting cylinder rotates to the rear of the limiting shaft, the limiting shaft will enter the interior of the limiting opening under the elastic force of the first extrusion spring. It should be understood here that when the limiting shaft does not enter the interior of the limiting opening, the first extrusion spring is always in a compressed state, which The limit can limit the rotating cylinder so that the two lifting plates are always under the guide rail. At this time, the first gear above the right lifting plate does not contact the right lifting plate. Therefore, the first gear above the right lifting plate will be in an idling state, and the first gear above the lifting plate will be in a rotating state until the running time of the electric motor ends. The first gear will stop rotating. At this time, the electromagnet is controlled to operate, and the moving frame is magnetically fixed by the electromagnet. Then the arc welding device body can be controlled to operate, and the switch cabinet above the electromagnet can be welded. It should be understood here that when the arc welding device body is performing welding, the operating cycles of all electric motors have not ended. Therefore, when the moving frame originally located on the left side of the fixed box moves to the front of the fixed box,The guide plate fixed on one side of the moving frame will pull the guide block and the limit shaft to move until the limit shaft is no longer engaged with the limit opening. At this time, the limit cylinder is no longer restricted by the limit shaft, so the rotating cylinder, the second gear and the winding drum will be reset under the pull of the first reset spring, and the two lifting plates will also move downward under the action of the first extrusion spring. It should be understood here that since the lifting plate will be simultaneously subjected to the pulling force of the rope when moving upward, the lifting plate will not be reset at the first time, but will be reset slowly. Therefore, after pulling the guide block, the moving frame will continue to move to the upper part of the left lifting plate and idle until the running time of the electric motor ends. Therefore, it can always be guaranteed that when the arc welding device body is welding a switch cabinet, there will be a switch cabinet waiting next to it, and the welding work will be carried out in a very short time;,

[0020] S2: When the switch cabinet with one side welded is moved along with the moving frame, the third gear and the electric motor, the third gear will pass through the third tooth plate, and the third tooth plate will be meshed with the third gear. It should be understood that before the third gear and the third tooth plate are meshed, the positioning plate is in a clamped state to clamp and fix the switch cabinet. Therefore, the third gear will rotate by means of the meshing connection with the third tooth plate, thereby driving the second transmission shaft fixed on the inner wall of the third gear to rotate. Therefore, the second transmission shaft transmits power to the rotating plate, thereby driving the rotating plate to rotate. When the rotating plate rotates, the sliding groove on its surface will squeeze the internal sliding plate to move, providing power for the movement of the sliding plate. However, the sliding plate is slidably connected to the inside of the positioning plate. Therefore, the sliding plate will only move along the groove on the surface of the positioning plate. At this time, the positioning plate clamped on the surface of the switch cabinet will gradually move away from the switch cabinet and stop clamping and fixing the switch cabinet. In addition, when the third gear drives the second transmission shaft to rotate, the second transmission shaft will wrap the second transmission rope and pull the second return spring to stretch.

[0021] S3: When the switch cabinet that has just been welded and needs heat dissipation moves to the middle position on the right side of the fixed box, the third gear will be driven by the third tooth plate to rotate clockwise, and the third gear will drive the second transmission shaft to rotate synchronously. When the second transmission shaft is rotating, the three sets of flip plates arranged on the outside of the second transmission shaft will push the first circular cylinder to rotate clockwise. Because the flip plates arranged on the outside of the second transmission shaft are rotatably connected to the inner wall of the fixed frame, and the right side of the flip plates are provided with limit plates, the flip plates arranged on the outside of the second transmission shaft can only rotate to the right. Similarly, The flip plate arranged on the outside of the rotating shaft will only rotate to the right side. Therefore, when the flip plate rotates along with the second transmission shaft, the flip plate will contact the inner wall of the first circular cylinder, thereby pushing the first circular cylinder to rotate clockwise. When the first circular cylinder rotates, it will push the flip plate on the outside of the rotating shaft to rotate to the right side. When the flip plate on the outside of the rotating shaft rotates, it will not be restricted by the limit plate. Therefore, the rotating shaft will fold up under the action of the first circular cylinder and will not push the rotating shaft to rotate. In addition, when the first circular cylinder rotates, it will drive the winding ring fixed on its outer surface. When the switch cabinet that has just been welded and needs to dissipate heat is moved to the middle position on the right side of the fixed box, the third gear will still be meshed by the third tooth plate, so the third gear and the second transmission shaft will still be restricted and unable to rotate. At this time, the telescopic rod is controlled to operate, and the long plate is pushed upward by the telescopic rod, so that the first circular cylinder can be driven to slide upward until the triangular block fixed on the inner wall of the first circular cylinder is no longer in contact with the flip plate on the outside of the second transmission shaft. At this time, the first circular cylinder is no longer restricted by the flip plate on the outside of the second transmission shaft, so the first circular cylinder will rotate in the opposite direction under the action of the third reset spring, thereby pushing the flip plate on the outside of the rotating shaft to rotate, thereby driving the rotating shaft, the rotating plate and the switch cabinet above the rotating plate to rotate. When the next round of electric motor operation cycle arrives, the operation of the electric motor will cause the third tooth plate to lose the meshing connection relationship with the third gear, so the third gear and the second transmission shaft will rotate in the direction under the action of the second reset spring, so that the positioning plate re-positions the switch cabinet, and then the telescopic rod is controlled to contract to reset the first circular cylinder.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention sets a multi-station switching mechanism, which can be used to allow the switch cabinet that has just welded a gap to enter the cooling area, while the other switch cabinet will directly enter the welding area for welding, which can not only increase the welding efficiency, but also fully dissipate the heat generated during the welding of the switch cabinet, avoiding the problem of deformation of the welding cabinet due to continuous high temperature.

[0024] 2. The present invention sets a limit unit, which can be used to limit the position of the switch cabinet that is being welded and moved, so that the switch cabinet will not deviate or have incorrect welding position due to the operation of the device when moving and welding.

[0025] 3. The present invention provides a rotating unit, which can be used to rotate the switch cabinet that has one or more gaps welded. By providing a multi-station switching mechanism, the limit unit and the rotating unit cooperate with each other, it can effectively avoid the problem of slow welding efficiency due to a small number of stations when the device is in use.

The outer surface of each first positioning shaft 233 and the second positioning shaft 236 are in contact with the outer surface of the rope 234. The corner position of the rope 234 can be limited by the second positioning shaft 236 and the first positioning shaft 233.

By providing the connecting plate 222 and the first roller 223, the first roller 223 can reduce the resistance encountered by the electric motor 217 when moving.

By providing the card slots 219 and the card block 218, the card block 218 and the fixed frame 202 can be removed by utilizing the relationship that the card block 218 is clamped inside the card slot 219.

By providing the cross plate 221 and the fan 220, the fan 220 can accelerate the dissipation of heat in the weld of the switch cabinet.

[0051] The specific implementation of this embodiment is as follows: first, when the device is needed, the arc welding device body 210 is controlled to operate, and the arc welding device body 210 is used to weld the switch cabinet placed on the surface of the rotating plate 3201. When a gap in the switch cabinet below the arc welding device body 210 is welded, the electromagnet 245 can be controlled to be closed. The electromagnet 245 will stop generating magnetic force when it is closed, so the moving frame 201 below the arc welding device body 210 will not be magnetically attracted. At this time, all the electric motors 217 can be controlled to operate. The operation of the electric motor 217 will drive the first gear 212 fixed at its output end to rotate, and three of the first gears 212 are in contact with the guide rail 225, which will guide the first gear 212 along the guide rail 225. The first gears 212 that are in contact with the surface of the lifting plate 229 will also enter the running track of the guide rail 225 under the guidance of the lifting plate 229, thereby the moving frame 201 and the rotating plate 3201 above can be driven to move by the first gears 212. It should be understood here that the running time of each electric motor 217 will make the moving frame 201 and the rotating plate 3201 move a quarter of a circle along the edge of the fixed box 203. It can be understood that the operation of all electric motors 217 will drive all the switch cabinets to be welded to move along the guide rail 225. With the operation of the electric motor 217, the upper right lifting plate 229 and the last fixed box 203 The moving frames 201 on both sides of the fixed box 203 will move a quarter of a circle, and when the moving frame 201 located above the leftmost lifting plate 229 is about to move to the top of the rightmost lifting plate 229 following the electric motor 217, the moving frame 201 located on the left side of the fixed box 203 will also follow the electric motor 217 to move to the left side of the second gear 208, and at this time, the teeth of the second gear 208 are in meshing relationship with the second tooth plate 204 in the moving frame 201 on the left side of the fixed box 203. As the electric motor 217 continues to run, the second tooth plate 204 will push the second gear 208 to rotate, and the rotation of the second gear 208 will drive the winding drum 207 to wind up the first transmission rope 243, and through the first circular plate 24 2 pulls the first return spring 241 outward, and the second gear 208 also drives the limiting cylinder 244 and the rotating cylinder 240 to rotate while rotating. The rotating cylinder 240 rotates and the rope 234 is wound around the surface of the rotating cylinder 240, so that the two lifting plates 229 can be pulled downward by the rope 234. When the limiting opening 230 opened on the surface of the limiting cylinder 244 rotates to the rear of the limiting shaft 226, the limiting shaft 226 enters the limiting opening 230 under the elastic force of the first extrusion spring 231. It should be understood that when the limiting shaft 226 does not enter the limiting opening 230, the first extrusion spring 231 is always in a compressed state, limiting the limiting cylinder 244, so that the rotating cylinder 240 can also be limited.The two lifting plates 229 are always under the guide rail 225. At this time, the first gear 212 above the right lifting plate 229 does not contact the right lifting plate 229. Therefore, the first gear 212 above the right lifting plate 229 will be in an idling state, and the first gear 212 above the lifting plate 229 will be in a rotating state until the running time of the electric motor 217 ends. The first gear 212 will stop rotating. At this time, the electromagnet 245 is controlled to operate, and the moving frame 201 is magnetically fixed by the electromagnet 245. Then the arc welding device body 210 can be controlled to operate, and the switch cabinet above the electromagnet 245 can be welded. It should be understood here that when the arc welding device body 210 is performing welding, the operating cycles of all electric motors 217 are not completed. Therefore, when the moving frame 201 originally located on the left side of the fixed box 203 moves to the front of the fixed box 203, the guide plate 205 fixed on one side of the moving frame 201 will pull the guide plate The block 227 and the limit shaft 226 move until the limit shaft 226 is no longer engaged with the limit opening 230. At this time, the limit cylinder 244 is no longer restricted by the limit shaft 226. Therefore, the rotating cylinder 240, the second gear 208 and the winding drum 207 will be reset under the pull of the first reset spring 241. At this time, the two lifting plates 229 will also move downward under the action of the first extrusion spring 231. It should be understood here that since the lifting plates 229 will be pulled by the rope 234 when moving upward, the lifting plates 229 will not be reset at the first time, but will be reset slowly. Therefore, after pulling the guide block 227, the moving frame 201 will continue to move to the top of the left lifting plate 229 and idle until the running time of the electric motor 217 ends. Therefore, it can always be guaranteed that when the arc welding device body 210 is welding a switch cabinet, there will be a switch cabinet waiting next to it, and the welding work will be carried out in a very short time.

[0052] Example 2: Please refer to Figure 3-Figure 5 The present invention provides a technical solution: a switch cabinet arc welding device capable of switching between multiple workstations. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The flipping mechanism 3 includes a limit unit 31, which is arranged above the processing bed 1. The limit unit 31 can clamp and fix the moving switch cabinet to be welded.

[0053] As a further limitation of the flipping mechanism 3 of the present invention, the limiting unit 31 includes a plurality of second transmission shafts 3106, each of which is rotatably connected to the inner wall of the rectangular block 213, the top of each second transmission shaft 3106 penetrates the moving frame 201 and extends to the inside of the moving frame 201, the outer surface of each second transmission shaft 3106 is rotatably connected to the inner wall of the moving frame 201, the upper surface of each rectangular block 213 is fixedly connected to a fixing seat 3102, the inner wall of each fixing seat 3102 is fixedly connected to a fixing cylinder 3103, the inner wall of each fixing cylinder 3103 is fixedly connected to a second return spring 3109, each second return spring 3109 is fixedly connected to a second circular plate 3108 at one end close to the second transmission shaft 3106, the back of each second circular plate 3108 is fixedly connected to a second transmission rope 3105, the outer surface of each second transmission rope 3105 is fixedly connected to the outer surface of the second transmission shaft 3106, and each second transmission shaft 3106 The outer surface of each of the third gears 3104 is fixedly connected, and the inner wall of the fixed box 203 is fixedly connected to the third tooth plate 3110, the outer surface of the third tooth plate 3110 is meshed with the outer surface of one of the third gears 3104, the outer surface of each second transmission shaft 3106 is fixedly connected to a rotating plate 3111, the upper surface of each rotating plate 3111 is provided with two groups of sliding grooves 3113, the number of each group of sliding grooves 3113 is two, the interior of each sliding groove 3113 is slidably connected with a sliding plate 3112, the upper surface of each sliding plate 3112 is fixedly connected with an extrusion plate 3101, and the inner wall of each moving frame 201 is fixedly connected with a positioning plate 3107, and the outer surface of each sliding plate 3112 is slidably connected to the interior of the positioning plate 3107. By setting a limiting unit 31, the limiting unit 31 can be used to limit the position of the switch cabinet being welded and moved, so that the switch cabinet will not deviate or the welding position is incorrect due to the operation of the device when moving and welding.

[0054] The specific implementation of this embodiment is as follows: when the switch cabinet with one side welded is moved along with the moving frame 201, the third gear 3104 and the electric motor 217, the third gear 3104 will pass through the third tooth plate 3110, and the third tooth plate 3110 will mesh with the third gear 3104. It should be understood that before the third gear 3104 and the third tooth plate 3110 are meshed, the positioning plate 3107 is in a clamping state to clamp and fix the switch cabinet, and when the third gear 3104 is meshed with the third gear plate 3110, the positioning plate 3107 is in a clamping state to clamp and fix the switch cabinet. When the first gear 212 is in meshing relationship with the third tooth plate 3110 and the second gear 208 and the second tooth plate 204, the first gear 212 will be in meshing relationship with the first tooth plate 224, so that the first gear 212 can move more stably, thereby avoiding the reaction force when the third gear 2104 is in meshing relationship with the third tooth plate 3110 and the second gear 208 and the second tooth plate 204 is greater than the friction between the first gear 3104 and the guide rail 225, resulting in the first gear 2104 being unable to utilize the friction between the guide rail 225. 5. In order to solve the problem of walking due to friction, the third gear 3104 will rotate by utilizing the meshing connection relationship with the third tooth plate 3110, thereby driving the second transmission shaft 3106 fixed to the inner wall of the third gear 3104 to rotate. Therefore, the second transmission shaft 3106 transmits power to the rotating plate 3111, thereby driving the rotating plate 3111 to rotate. When the rotating plate 3111 rotates, the sliding groove 3113 on the surface thereof will squeeze the internal sliding plate 3112 to move, thereby facilitating the movement of the sliding plate 3112. Power is provided, but the sliding plate 3112 is slidably connected to the inside of the positioning plate 3107, so the sliding plate 3112 will only move along the groove opened on the surface of the positioning plate 3107. At this time, the positioning plate 3107 clamped on the surface of the switch cabinet will gradually move away from the switch cabinet and stop clamping the switch cabinet. In addition, when the third gear 3104 drives the second transmission shaft 3106 to rotate, the second transmission shaft 3106 will wind up the second transmission rope 3105 and pull the second return spring 3109 to stretch.

[0055] Example 3: Please refer to Figure 5-Figure 8 The present invention provides a technical solution: a switch cabinet arc welding device capable of multi-station switching. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The flipping mechanism 3 also includes a rotating unit 32, which is arranged above the processing bed 1. The rotating unit 32 cooperates with the limiting unit 31 to enable the switch cabinet to rotate automatically.

[0056] As a further limitation of the flip mechanism 3 of the present invention, the rotating unit 32 includes a plurality of rotating plates 3201, the bottom surface of each rotating plate 3201 is fixedly connected to a rotating shaft 3202, the outer surface of each rotating shaft 3202 is rotatably connected to the inner wall of the moving frame 201, the interior of each moving frame 201 is slidably connected to a long plate 3204, and two telescopic rods 3214 are arranged below each long plate 3204, the telescopic end of each telescopic rod 3214 is fixedly connected to the bottom surface of the long plate 3204, and the outer surface of each telescopic rod 3214 is fixedly connected to the positioning plate 31 07, the inner wall of each long plate 3204 is rotatably connected to the first circular cylinder 3207, the outer surface of each first circular cylinder 3207 is fixedly connected to the winding ring 3203, the upper surface of each long plate 3204 is fixedly connected to the second circular cylinder 3205, the inner wall of each second circular cylinder 3205 is fixedly connected to the third return spring 3208, the end of each third return spring 3208 close to the winding ring 3203 is fixedly connected to the third circular plate 3209, and the side of each third circular plate 3209 close to the winding ring 3203 is fixedly connected to the third return spring 3208. There are three transmission ropes 3206, one end of each third transmission rope 3206 is fixedly connected to the outer surface of the winding ring 3203, the bottom end of each first circular cylinder 3207 is in contact with the top end of the second transmission shaft 3106, the top end of each first circular cylinder 3207 is in contact with the bottom end of the rotating shaft 3202, and the outer surface of each rotating shaft 3202 and the second transmission shaft 3106 is fixedly connected with three groups of fixed frames 3210, and the number of each group of fixed frames 3210 is two, and the inner wall of each group of fixed frames 3210 is rotatably connected with a flip plate 3211, and each fixed frame 3210 One side of the device is fixedly connected to a limiting plate 3213 and a third extrusion spring 3212, and each of the fixed frame 3210, the flip plate 3211, the limiting plate 3213 and the third extrusion spring 3212 are arranged inside the first circular cylinder 3207. By setting a rotating unit 32, the rotating unit 32 can be used to rotate the switch cabinet that has one or more gaps welded. By setting a multi-station switching mechanism 2, the mutual cooperation between the limiting unit 31 and the rotating unit 32 can effectively avoid the problem of slow welding efficiency due to a small number of stations when the device is in use.

[0057] The specific implementation of this embodiment is as follows: when the switch cabinet that has just been welded and needs heat dissipation moves to the middle position on the right side of the fixed box 203, the third gear 3104 will be driven by the third tooth plate 3110 to rotate in a clockwise direction, and the third gear 3104 will drive the second transmission shaft 3106 to rotate synchronously. When the second transmission shaft 3106 is rotating, the three groups of flip plates 3211 arranged on the outside of the second transmission shaft 3106 will push the first circular cylinder 3207 to rotate in a clockwise direction. Because the flip plates 3211 arranged on the outside of the second transmission shaft 3106 are rotatably connected to the inner wall of the fixed frame 3210, and the right side of the flip plates 3211 are all provided with limit plates 3213, the flip plates 3211 arranged on the outside of the second transmission shaft 3106 The rotating plate 3211 can only rotate to the right side. Similarly, the flip plate 3211 arranged on the outer side of the rotating shaft 3202 can only rotate to the right side. It should be understood here that the rotating shaft 3202 divides the flip plate 3211 into two parts, and the limiting plate 3213 only limits the rear half of the flip plate 3211. Therefore, the rear half of the flip plate 3211 cannot rotate to the right side, and the front half and the rear half of the flip plate 3211 rotate in opposite directions. Therefore, the front half of the flip plate 3211 can only rotate to the right side, so the flip plate 3211 as a whole can only rotate to the right side. Therefore, when the flip plate 3211 rotates following the second transmission shaft 3106, the flip plate 3211 will contact the inner wall of the first circular cylinder 3207. The first circular cylinder 3207 is in contact with the first circular cylinder 3207, thereby pushing the first circular cylinder 3207 to rotate clockwise as well. When the first circular cylinder 3207 rotates, it pushes the flip plate 3211 on the outside of the rotating shaft 3202 to rotate to the right. When the flip plate 3211 on the outside of the rotating shaft 3202 rotates, it will not be restricted by the limit plate 3213. Therefore, the rotating shaft 3202 will be folded up under the action of the first circular cylinder 3207 and will not push the rotating shaft 3202 to rotate. In addition, when the first circular cylinder 3207 rotates, it will drive the winding ring 3203 fixed on its outer surface to rotate, so that the third transmission rope 3206 can be wound around the surface of the winding ring 3203 and the third reset spring 3208 can be stretched. When the third gear 3104 moves to the middle position on the right side of the fixed box 203, the third gear 3104 will still be meshed with the third tooth plate 3110. Therefore, the third gear 3104 and the second transmission shaft 3106 will still be restricted and unable to rotate. At this time, the telescopic rod 3214 is controlled to operate, and the telescopic rod 3214 is used to push the long plate 3204 to move upward, thereby driving the first circular cylinder 3207 to slide upward until the triangular block fixed on the inner wall of the first circular cylinder 3207 is no longer in contact with the flip plate 3211 on the outer side of the second transmission shaft 3106. At this time, the first circular cylinder 3207 is no longer restricted by the flip plate 3211 on the outer side of the second transmission shaft 3106. Therefore, the first circular cylinder 3207 will rotate in the opposite direction under the action of the third return spring 3208.This can drive the flip plate 3211 outside the rotating shaft 3202 to rotate, thereby driving the rotating shaft 3202, the rotating plate 3201 and the switch cabinet above the rotating plate 3201 to rotate. When the next round of the electric motor 217 operation cycle arrives, the operation of the electric motor 217 will cause the third tooth plate 3110 to lose the meshing connection relationship with the third gear 3104. Therefore, the third gear 3104 and the second transmission shaft 3106 will rotate in the direction under the action of the second reset spring 3109, so that the positioning plate 3107 can reposition the switch cabinet, and then the telescopic rod 3214 can be controlled to contract to reset the first circular cylinder 3207.

[0058] A method for processing a switch cabinet arc welding device capable of switching multiple workstations comprises the following steps:

[0059] S1: First, when the present device is needed, the arc welding device body 210 is controlled to operate, and the arc welding device body 210 is used to weld the switch cabinet placed on the surface of the rotating plate 3201. When a gap of the switch cabinet below the arc welding device body 210 is welded, the electromagnet 245 can be controlled to be closed. The closing of the electromagnet 245 will stop generating magnetic force, so the moving frame 201 below the arc welding device body 210 will not be magnetically attracted. At this time, all the electric motors 217 can be controlled to operate. The operation of the electric motor 217 will drive the first gear 212 fixed at its output end to rotate, and three of the first gears 212 are in contact with the guide rail 225, which will guide the first gear 212 to move along the guide rail 225, and the other two The first gear 212 is in contact with the outer surface of the lifting plate 229, and the first gear 212 in contact with the surface of the lifting plate 229 will also enter the running track of the guide rail 225 under the guidance of the lifting plate 229, thereby the upper moving frame 201 and the rotating plate 3201 can be driven to move by the first gear 212. It should be understood here that the running time of each electric motor 217 will make the moving frame 201 and the rotating plate 3201 move a quarter of a circle along the edge of the fixed box 203. It can be understood that the operation of all electric motors 217 will drive all the switch cabinets to be welded to move along the guide rail 225. With the operation of the electric motor 217, the upper right lifting plate 229, the rear of the fixed box 203 and the fixed The moving frames 201 on both sides of the box 203 will move a quarter of a circle, and when the moving frame 201 located above the leftmost lifting plate 229 is about to move to the top of the rightmost lifting plate 229 following the electric motor 217, the moving frame 201 located on the left side of the fixed box 203 will also follow the electric motor 217 to move to the left side of the second gear 208, and at this time, the teeth of the second gear 208 are in meshing relationship with the second tooth plate 204 in the moving frame 201 on the left side of the fixed box 203. As the electric motor 217 continues to run, the second tooth plate 204 will push the second gear 208 to rotate, and the rotation of the second gear 208 will drive the winding drum 207 to wind up the first transmission rope 243, and pull it through the first circular plate 242. The first return spring 241 is stretched outward, and the second gear 208 also drives the limiting cylinder 244 and the rotating cylinder 240 to rotate while rotating. The rotation of the rotating cylinder 240 will wrap the rope 234 around the surface of the rotating cylinder 240, so that the two lifting plates 229 can be pulled downward by the rope 234. When the limiting opening 230 opened on the surface of the limiting cylinder 244 rotates to the rear of the limiting shaft 226, the limiting shaft 226 will enter the limiting opening 230 under the elastic force of the first extrusion spring 231. It should be understood here that when the limiting shaft 226 does not enter the limiting opening 230, the first extrusion spring 231 is always in a compressed state, limiting the limiting cylinder 244, so that the rotating cylinder 240 can also be limited.The two lifting plates 229 are always under the guide rail 225. At this time, the first gear 212 above the right lifting plate 229 does not contact the right lifting plate 229. Therefore, the first gear 212 above the right lifting plate 229 will be in an idling state, and the first gear 212 above the lifting plate 229 will be in a rotating state until the running time of the electric motor 217 ends. The first gear 212 will stop rotating. At this time, the electromagnet 245 is controlled to operate, and the moving frame 201 is magnetically fixed by the electromagnet 245. Then the arc welding device body 210 can be controlled to operate, and the switch cabinet above the electromagnet 245 can be welded. It should be understood here that when the arc welding device body 210 is performing welding, the operating cycles of all electric motors 217 are not completed. Therefore, when the moving frame 201 originally located on the left side of the fixed box 203 moves to the front of the fixed box 203, the guide plate 205 fixed on one side of the moving frame 201 will pull the guide plate The block 227 and the limit shaft 226 move until the limit shaft 226 is no longer engaged with the limit opening 230. At this time, the limit cylinder 244 is no longer restricted by the limit shaft 226. Therefore, the rotating cylinder 240, the second gear 208 and the winding drum 207 will be reset under the pull of the first reset spring 241. At this time, the two lifting plates 229 will also move downward under the action of the first extrusion spring 231. It should be understood here that since the lifting plates 229 will be pulled by the rope 234 when moving upward, the lifting plates 229 will not be reset at the first time, but will be reset slowly. Therefore, after pulling the guide block 227, the moving frame 201 will continue to move to the upper part of the left lifting plate 229 and idle until the running time of the electric motor 217 ends. Therefore, it can always be guaranteed that when the arc welding device body 210 is welding a switch cabinet, there will be a switch cabinet waiting next to it, and the welding work will be carried out in a very short time;

[0060] S2: When the switch cabinet whose side has been welded moves along with the moving frame 201, the third gear 3104 and the electric motor 217, the third gear 3104 will pass through the third tooth plate 3110, and the third tooth plate 3110 will mesh with the third gear 3104. It should be understood that before the third gear 3104 and the third tooth plate 3110 mesh, the positioning plate 3107 is in a clamping state to clamp and fix the switch cabinet. Therefore, the third gear 3104 will rotate by utilizing the meshing connection relationship with the third tooth plate 3110, thereby driving the second transmission shaft 3106 fixed to the inner wall of the third gear 3104 to rotate. Therefore, the second transmission shaft 3106 transmits power to the rotating plate 3111 The rotating plate 3111 can be driven to rotate, and the sliding groove 3113 on the surface of the rotating plate 3111 will squeeze the sliding plate 3112 inside to move, providing power for the movement of the sliding plate 3112, but the sliding plate 3112 is slidably connected to the inside of the positioning plate 3107, so the sliding plate 3112 can only move along the groove on the surface of the positioning plate 3107. At this time, the positioning plate 3107 clamped on the surface of the switch cabinet will gradually move away from the switch cabinet and stop clamping the switch cabinet. In addition, when the third gear 3104 drives the second transmission shaft 3106 to rotate, the second transmission shaft 3106 will wind up the second transmission rope 3105 and pull the second return spring 3109 to stretch.

[0061] S3: When the switch cabinet that has just been welded and needs heat dissipation moves to the middle position on the right side of the fixed box 203, the third gear 3104 will be driven by the third tooth plate 3110 to rotate clockwise, and the third gear 3104 will drive the second transmission shaft 3106 to rotate synchronously. When the second transmission shaft 3106 rotates, the three groups of flip plates 3211 arranged on the outside of the second transmission shaft 3106 will push the first circular cylinder 3207 to rotate clockwise. Because the flip plate 3211 arranged on the outside of the second transmission shaft 3106 is rotatably connected to the inner wall of the fixed frame 3210, and the right side of the flip plate 3211 is provided with a limit plate 3213, the flip plate 3211 arranged on the outside of the second transmission shaft 3106 can only rotate to the right. Similarly, the flip plate 3211 arranged on the outside of the rotating shaft 3202 will only rotate to the right side. Therefore, when the flip plate 3211 rotates along with the second transmission shaft 3106, the flip plate 3211 will contact the inner wall of the first circular cylinder 3207, thereby pushing the first circular cylinder 3207 to rotate clockwise as well. When the first circular cylinder 3207 rotates, it will push the flip plate 3211 on the outside of the rotating shaft 3202 to rotate to the right side. When the flip plate 3211 on the outside of the rotating shaft 3202 rotates, it will not be restricted by the limit plate 3213. Therefore, the rotating shaft 3202 will be folded up under the action of the first circular cylinder 3207 and will not push the rotating shaft 3202 to rotate. In addition, when the first circular cylinder 3207 rotates, it will drive the The wire winding ring 3203 fixed on the outer surface rotates, so that the third transmission rope 3206 can be wound around the surface of the wire winding ring 3203 and the third reset spring 3208 can be stretched. When the switch cabinet that has just been welded and needs heat dissipation is moved to the middle position on the right side of the fixed box 203, the third gear 3104 will still be engaged with the third tooth plate 3110. Therefore, the third gear 3104 and the second transmission shaft 3106 will still be restricted and unable to rotate. At this time, the telescopic rod 3214 is controlled to operate, and the telescopic rod 3214 is used to push the long plate 3204 to move upward, thereby driving the first circular cylinder 3207 to slide upward until the triangular block fixed on the inner wall of the first circular cylinder 3207 is no longer in contact with the flip plate 3211 on the outer side of the second transmission shaft 3106. The first circular cylinder 3207 is no longer restricted by the flip plate 3211 on the outer side of the second transmission shaft 3106. Therefore, the first circular cylinder 3207 will rotate in the opposite direction under the action of the third return spring 3208, thereby pushing the flip plate 3211 on the outer side of the rotating shaft 3202 to rotate, thereby driving the rotating shaft 3202, the rotating plate 3201 and the switch cabinet above the rotating plate 3201 to rotate. When the next round of operation cycle of the electric motor 217 comes, the operation of the electric motor 217 will cause the third tooth plate 3110 to lose the meshing connection relationship with the third gear 3104. Therefore, the third gear 3104 and the second transmission shaft 3106 will rotate in the opposite direction under the action of the second return spring 3109, so that the positioning plate 3107 can re-position the switch cabinet.Then, the telescopic rod 3214 is controlled to retract to reset the first circular cylinder 3207.

10. A processing method for a switch cabinet arc welding device capable of multi-station switching according to any one of claims 1 to 9, characterized in that: The specific steps include: S1: First, when the present device is needed, the arc welding device body (210) is controlled to operate, and the arc welding device body (210) is used to weld the switch cabinet placed on the surface of the rotating plate (3201). When a gap of the switch cabinet below the arc welding device body (210) is welded, the electromagnet (245) can be controlled to be turned off. When the electromagnet (245) is turned off, the magnetic force will stop being generated, so the moving frame (201) located below the arc welding device body (210) will not be attracted by the magnet. At this time, all the electric motors (217) can be controlled to operate. The operation of the electric motors (217) will drive the first gears (212) fixed at their output ends to rotate, and three of the first gears (212) are in contact with the guide rails (225). The contact relationship will guide the first gear (212) to move along the guide rail (225), and the other two first gears (212) are in contact with the outer surface of the lifting plate (229), and the first gear (212) in contact with the surface of the lifting plate (229) will also enter the running track of the guide rail (225) under the guidance of the lifting plate (229), thereby driving the upper moving frame (201) and the rotating plate (3201) to move through the first gear (212). It should be understood here that the running time of each electric motor (217) will cause the moving frame (201) and the rotating plate (3201) to move a quarter of a circle along the edge of the fixed box (203). It can be understood that all electric motors (217) ) operation will drive all the switch cabinets to be welded to move along the guide rail (225). With the operation of the electric motor (217), the moving frames (201) located above the right lifting plate (229), at the rear of the fixed box (203) and on both sides of the fixed box (203) will move a quarter of a circle. When the moving frame (201) located above the leftmost lifting plate (229) is about to move to the top of the rightmost lifting plate (229) following the electric motor (217), the moving frame (201) located on the left side of the fixed box (203) will also follow the electric motor (217) to move to the left side of the second gear (208), and at this time, the teeth of the second gear (208) and the moving frame (201) on the left side of the fixed box (203) are aligned. The second tooth plate (204) in the moving frame (201) is in meshing relationship. As the electric motor (217) continues to run, the second tooth plate (204) will push the second gear (208) to rotate. The rotation of the second gear (208) will drive the winding drum (207) to wind up the first transmission rope (243), and pull the first return spring (241) outward through the first circular plate (242). In addition, the second gear (208) will also drive the limit cylinder (244) and the rotating cylinder (240) to rotate while rotating. The rotation of the rotating cylinder (240) will wind the rope (234) around the surface of the rotating cylinder (240), thereby pulling the two lifting plates (229) downward through the rope (234).When the limiting opening (230) opened on the surface of the limiting cylinder (244) rotates to the rear of the limiting shaft (226), the limiting shaft (226) will enter the limiting opening (230) under the elastic force of the first extrusion spring (231). It should be understood that when the limiting shaft (226) has not entered the limiting opening (230), the first extrusion spring (231) is always in a compressed state, limiting the limiting cylinder (244), thereby limiting the rotating cylinder (240), so that the two lifting plates (229) are always below the guide rail (225). At this time, the first gear (212) above the right lifting plate (229) is not in contact with the right lifting plate (229). The plate (229) contacts the first gear (212) above the right lifting plate (229), so the first gear (212) above the lifting plate (229) will be in an idling state all the time, and the first gear (212) above the lifting plate (229) will be in a rotating state all the time until the running time of the electric motor (217) ends and the first gear (212) stops rotating. At this time, the electromagnet (245) is controlled to operate, and the moving frame (201) is magnetically fixed by the electromagnet (245). Then, the arc welding device body (210) can be controlled to operate, and the switch cabinet above the electromagnet (245) can be welded. It should be understood that when the arc welding device body (210) is performing welding, all electric motors are in a state of rotation. Therefore, when the moving frame (201) originally located on the left side of the fixed box (203) moves to the front of the fixed box (203), the guide plate (205) fixed on one side of the moving frame (201) will pull the guide block (227) and the limit shaft (226) to move until the limit shaft (226) is no longer engaged with the limit opening (230). At this time, the limit cylinder (244) is no longer restricted by the limit shaft (226). Therefore, the rotating cylinder (240), the second gear (208) and the winding drum (207) will be reset under the pull of the first reset spring (241). At this time, the two lifting plates (229) will also be in the first squeeze The lifting plate (229) moves downward under the action of the compression spring (231). It should be understood that when the lifting plate (229) moves upward, it will be simultaneously subjected to the pulling force of the rope (234). Therefore, the lifting plate (229) will not be reset immediately, but will be reset slowly. Therefore, after pulling the guide block (227), the moving frame (201) will continue to move to the top of the left lifting plate (229) and idle until the running time of the electric motor (217) ends. Therefore, it can always be ensured that when the arc welding device body (210) is welding a switch cabinet, there will always be a switch cabinet waiting next to it, and the welding work will be carried out in a very short time. S2: When the switch cabinet with one side welded is moved along with the moving frame (201), the third gear (3104) and the electric motor (217), the third gear (3104) will pass through the third tooth plate (3110), and the third tooth plate (3110) and the third gear (3104) will be in meshing relationship. It should be understood that before the third gear (3104) and the third tooth plate (3110) are in meshing relationship, the positioning plate (3107) is in a clamping state to clamp and fix the switch cabinet. Therefore, the third gear (3104) will rotate by utilizing the meshing connection relationship with the third tooth plate (3110), thereby driving the second transmission shaft (3106) fixed on the inner wall of the third gear (3104) to rotate. Therefore, the second transmission shaft (3106) transmits power to the rotating plate (3111). ), thereby driving the rotating plate (3111) to rotate, and when the rotating plate (3111) rotates, the sliding groove (3113) provided on its surface will squeeze the sliding plate (3112) inside to move, providing power for the movement of the sliding plate (3112), but the sliding plate (3112) is slidably connected to the inside of the positioning plate (3107), so the sliding plate (3112) can only move along the groove provided on the surface of the positioning plate (3107), at this time, the positioning plate (3107) clamped on the surface of the switch cabinet will gradually move away from the switch cabinet, and stop clamping and fixing the switch cabinet, in addition, when the third gear (3104) drives the second transmission shaft (3106) to rotate, the second transmission shaft (3106) will wind up the second transmission rope (3105), and will pull the second return spring (3109) to stretch; S3: When the switch cabinet that has just been welded and needs to dissipate heat moves to the middle position of the left and right sides of the fixed box (203), the third gear plate (3110) will drive the third gear (3104) to rotate clockwise, and the third gear (3104) will drive the second transmission shaft (3106) to rotate synchronously. When the second transmission shaft (3106) rotates, the three groups of flip plates (3211) arranged on the outside of the second transmission shaft (3106) will push the first circular cylinder (3207) to rotate clockwise. Because the flip plate (3211) arranged on the outside of the second transmission shaft (3106) is rotatably connected to the inner wall of the fixed frame (3210), and the right side of the flip plate (3211) is provided with a limit plate (3213), the first circular cylinder (3207) is also rotated in the clockwise direction. The flip plate (3211) arranged on the outside of the second transmission shaft (3106) can only rotate to the right. Similarly, the flip plate (3211) arranged on the outside of the rotating shaft (3202) can only rotate to the right. Therefore, when the flip plate (3211) rotates along with the second transmission shaft (3106), the flip plate (3211) will contact the inner wall of the first circular cylinder (3207), thereby pushing the first circular cylinder (3207) to rotate clockwise. When the first circular cylinder (3207) rotates, it pushes the flip plate (3211) on the outside of the rotating shaft (3202) to rotate to the right. When the flip plate (3211) on the outside of the rotating shaft (3202) rotates, it will not be restricted by the limit plate (3213). Therefore, the rotating shaft (3202) 3202) will fold up under the action of the first circular cylinder (3207) and will not push the rotating shaft (3202) to rotate. In addition, when the first circular cylinder (3207) rotates, it will drive the winding ring (3203) fixed on its outer surface to rotate, so that the third transmission rope (3206) can be wound around the surface of the winding ring (3203) and the third reset spring (3208) can be stretched. When the switch cabinet that has just been welded and needs to dissipate heat is moved to the middle position on the right side of the fixed box (203), the third gear (3104) will still be engaged by the third tooth plate (3110), so the third gear (3104) and the second transmission shaft (3106) will still be restricted and unable to rotate. At this time, the telescopic rod (3214) is controlled to operate. , the telescopic rod (3214) is used to push the long plate (3204) to move upward, thereby driving the first circular cylinder (3207) to slide upward until the triangular block fixed on the inner wall of the first circular cylinder (3207) is no longer in contact with the flip plate (3211) on the outer side of the second transmission shaft (3106). At this time, the first circular cylinder (3207) is no longer restricted by the flip plate (3211) on the outer side of the second transmission shaft (3106). Therefore, the first circular cylinder (3207) will rotate in the opposite direction under the action of the third return spring (3208), thereby driving the flip plate (3211) on the outer side of the rotating shaft (3202) to rotate, thereby driving the rotating shaft (3202), the rotating plate (3201) and the switch cabinet above the rotating plate (3201) to rotate.When the next round of operation cycle of the electric motor (217) arrives, the operation of the electric motor (217) causes the third tooth plate (3110) to lose the meshing connection with the third gear (3104), so the third gear (3104) and the second transmission shaft (3106) will rotate in the direction under the action of the second reset spring (3109), so that the positioning plate (3107) repositions the switch cabinet, and then the telescopic rod (3214) is controlled to contract to reset the first circular cylinder (3207).
