Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] When welding distribution cabinets using existing welding equipment, the welding is usually done manually after the distribution cabinet is fixed in place. Manual welding may result in low production efficiency and unstable welding quality.
[0020] In view of this, the present invention provides a welding device for processing power distribution cabinets. Through the cooperation between the fixed plate, the slide groove and the movable plate, when welding a power distribution cabinet is required, the power distribution cabinet is placed on the top of the workbench, and the two sides of the power distribution cabinet are respectively pressed against the sides of the two fixed plates. Then, the movable plate is moved on the inner wall of the slide groove until it is pressed against the other two sides of the power distribution cabinet. After being pressed, the movable plate is fixed to the top of the workbench by the mounting ears. This fixing method can expose the welding position of the power distribution cabinet to the outside without re-clamping. Moreover, due to the adjustability of the movable plate, power distribution cabinets of different specifications can be fixed.
[0021] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0022] Example 1: By Figure 1-4 It is known that a welding device for processing power distribution cabinets includes a workbench 1, a welding torch 12 is arranged above the workbench 1, and the welding device for processing power distribution cabinets also includes a fixing device 2 and a control device 3. The fixing device 2 is installed above the workbench 1; the control device 3 is arranged outside the welding torch 12; wherein, the power distribution cabinet is fixed by the fixing device 2, and the control device 3 controls the movement trajectory of the welding torch 12.
[0023] In the specific implementation process, it is worth noting that the welding work of the power distribution cabinet is completed by the welding gun 12, the fixing device 2 is fixed according to the specifications of the power distribution cabinet, and the position to be welded can be exposed. The control device 3 controls the movement trajectory of the welding gun 12 to realize automated welding.
[0024] Furthermore, the fixing device 2 includes a fixing plate 21, a slide 22, a movable plate 23, mounting ears 24, and a driving device 25. Two fixing plates 21 are provided, both fixedly connected to the top of the workbench 1; two slides 22 are provided, both opened on the top of the workbench 1 and corresponding to the fixing plates 21; the movable plate 23 is slidably engaged with the inner wall of the slide 22; the mounting ears 24 are fixedly connected to the outer wall of the movable plate 23 and fixed to the top of the workbench 1 by bolts; the driving device 25 is installed between the workbench 1 and the welding torch 12; wherein, the two fixing plates 21 are pressed against the two sides of the power distribution cabinet, the movable plate 23 moves in the inner wall of the slide 22 until it is pressed against the other two sides of the power distribution cabinet, the movable plate 23 is fixed to the top of the workbench 1 by the mounting ears 24, and the driving device 25 drives the welding torch 12 to move;
[0025] In the specific implementation process, it is worth noting that when welding the distribution cabinet is required, the distribution cabinet is placed on the top of the workbench 1, and the two sides of the distribution cabinet are pressed against the sides of the two fixed plates 21 respectively. Then, the movable plate 23 is moved on the inner wall of the slide 22 until it is pressed against the other two sides of the distribution cabinet. After it is pressed, the movable plate 23 is fixed to the top of the workbench 1 by using the mounting ears 24. This fixing method can expose the welding position of the distribution cabinet to the outside without re-clamping. Moreover, the adjustableness of the movable plate 23 can fix distribution cabinets of different specifications.
[0026] Furthermore, the drive device 25 includes an arc-shaped electric slide rail 251, a first electric slider 252, a mounting plate 253, a telescopic rod 254, a straight electric slide rail 255, and a second electric slider 256. The arc-shaped electric slide rail 251 is fixedly connected to the top of the workbench 1; the first electric slider 252 is slidably engaged with the outer wall of the arc-shaped electric slide rail 251; the mounting plate 253 is fixedly connected to the top of the first electric slider 252; the telescopic rod 254 is fixedly connected to the side of the outer wall of the mounting plate 253 away from the fixed plate 21; the straight electric slide rail 255 is fixedly connected to the output end of the telescopic rod 254; and the second electric slider 256 is slidably engaged with the outer wall of the second electric slider 256. The arc-shaped electric slide rail 251 and the first electric slider 252 drive the welding torch 12 to move around the distribution cabinet via the mounting plate 253, the telescopic rod 254 drives the welding torch 12 to move closer to the distribution cabinet, and the straight electric slide rail 255 and the second electric slider 256 drive the welding torch 12 to move up and down.
[0027] In the specific implementation process, it is worth noting that during the welding work, the first electric slider 252 drives the welding torch 12 to move along the arc-shaped electric slide rail 251, that is, to move around the power distribution cabinet. When it moves to the position where welding is required, the output end of the telescopic rod 254 drives the straight electric slide rail 255. The straight electric slide rail 255 drives the welding torch 12 to move towards the power distribution cabinet. After the welding torch 12 reaches the welding position, the welding torch 12 moves up and down along the power distribution cabinet under the drive of the second electric slider 256, and finally completes the welding work, realizing automated welding. The arc-shaped electric slide rail 251 is model HCR12A6+60, and the straight electric slide rail 255 is model MSA15S-N.
[0028] Specifically, when using the welding device for processing the distribution cabinet, if welding is required, place the distribution cabinet on top of the workbench 1, and press both sides of the distribution cabinet against the sides of the two fixed plates 21 respectively. Then, move the movable plate 23 along the inner wall of the slide 22 until it presses against the other two sides of the distribution cabinet. After pressing, fix the movable plate 23 to the top of the workbench 1 using the mounting ears 24. This fixing method exposes the welding position of the distribution cabinet, eliminating the need for re-clamping. Furthermore, the adjustability of the movable plate 23 allows for adjustments to the welding position. When a distribution cabinet of the same specification is fixed, during the welding operation, the first electric slider 252 drives the welding torch 12 to move along the arc-shaped electric slide rail 251, that is, to move around the distribution cabinet. When it moves to the position where welding is required, the output end of the telescopic rod 254 drives the straight electric slide rail 255. The straight electric slide rail 255 drives the welding torch 12 to move towards the distribution cabinet. After the welding torch 12 reaches the welding position, the welding torch 12 moves up and down along the distribution cabinet under the drive of the second electric slider 256, and finally completes the welding work, realizing automated welding.
[0029] Example 2: From Figure 1-4 It is known that the control device 3 includes a controller 31, a position sensor 32, and a force sensor 33. The controller 31 is installed on the front of the workbench 1. The position sensor 32 is fixed to the outer wall of the mounting plate 253 near the telescopic rod 254 by bolts. The force sensor 33 is fixed to the outer wall of the second electric slider 256 away from the telescopic rod 254 by bolts, and the welding torch 12 is installed at the end of the force sensor 33 away from the second electric slider 256. The controller 31 controls the movement of the first electric slider 252 and the second electric slider 256. The position information of the first electric slider 252 is transmitted to the controller 31 through the position sensor 32, and the contact force information between the welding torch 12 and the power distribution cabinet is transmitted to the controller 31 through the force sensor 33.
[0030] In the specific implementation process, it is worth noting that the controller 31 is model VELMEX and is electrically connected to the arc-shaped electric slide rail 251. Locate the wiring terminals on the motor or drive module of the arc-shaped electric slide rail 251, and correctly connect the corresponding pins of the cable to the terminals according to the instruction manuals of the controller 31 and the motor. Generally, it is necessary to connect the positive and negative terminals of the power supply and the control signal line. During welding, first determine the welding position according to the specifications of the power distribution cabinet and record the welding position data. Then, the position information of the welding torch 12 is transmitted to the controller 31 through the position sensor 32. The microprocessor or dedicated motion control card in the controller 31 processes and analyzes these signals, converts the raw data detected by the position sensor 32 into the actual position coordinates of the welding torch 12, and compares it with the preset welding position coordinates to calculate the deviation between the welding torch 12 and the target position. Based on the deviation calculated by the controller 31, the control system sends a control signal to the drive motor of the arc-shaped electric slide rail 251. The drive motor adjusts the slide rail according to the received signal. The movement of the welding torch 12 causes it to move along an arc-shaped trajectory, gradually approaching the target welding position. During this process, the position sensor 32 continuously detects the position of the welding torch 12 in real time and feeds the information back to the control system, forming a closed-loop control circuit. This allows the control system to continuously adjust the movement of the slide rail according to the actual situation, ensuring that the welding torch 12 accurately reaches the target welding position. The force sensor 33 is installed between the welding torch 12 and the second electric slider 256, and can detect the force on the welding torch 12 in all directions in real time. When the welding torch 12 contacts the power distribution cabinet, the force sensor 33 monitors the contact between the welding torch 12 and the welding position of the power distribution cabinet, avoiding incomplete contact that could lead to incomplete welding. Welding is carried out along the preset welding path. The position sensor 32 is model MLX90365KDC, and the force sensor 33 is model MA23. The position sensor 32 is installed on the surface of the mounting plate 253 and can monitor the position of the welding torch 12 in real time. Both the position sensor 32 and the force sensor 33 are wirelessly connected to the controller 31.
[0031] Furthermore, brackets 11 are fixedly connected to the four corners of the bottom of the workbench 1;
[0032] In the specific implementation process, it is worth noting that the bracket 11 can provide support for the workbench 1, making the welding work more stable.
[0033] Specifically, based on the above embodiment 1, the position information monitored by the position sensor 32 of the welding torch 12 is transmitted to the controller 31. The controller 31 controls the arc-shaped electric slide rail 251 by pre-recording the required welding position of the power distribution cabinet, thereby achieving the effect of automatically finding the welding position. Through the action of the force sensor 33, the contact between the welding torch 12 and the power distribution cabinet is ensured to complete the welding work.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
