Description

Technical Field

[0001] This utility model relates to the field of power distribution box processing technology, specifically a punching device for the door of a power distribution equipment cabinet. Background Technology

[0002] In the mass production process of distribution boxes, the punching process of the box door is a core link that directly affects the functionality and safety of the product. The holes at the top and bottom of the box door not only undertake the task of heat dissipation during equipment operation to ensure that the internal components work stably in a suitable temperature environment, but also need to meet the needs of cable entry and exit path planning.

[0003] However, in traditional punching operations, operators must first fix the box door to the worktable of the punching equipment using clamps. After completing the punching operation on one side, if the other side needs to be punched, the fixed box door must be disassembled, its placement angle and position adjusted, and then it must be clamped and fixed again before the equipment can be started for secondary punching. In this process, auxiliary operations such as disassembly, repositioning, and fixing consume a lot of effective working time, which not only prolongs the processing cycle of a single box door, but also increases the risk of substandard hole position accuracy due to positioning deviations that may occur from multiple clamping, further affecting the production qualification rate. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a punching device for a power distribution equipment cabinet door, comprising a movable plate and a movable component located on the top of the movable plate, and punching components distributed on the left and right sides of the movable plate. The movable plate is also equipped with a four-way positioning component and a door-removing component. The door-removing component includes two sets of bidirectional pushing parts, each with a rake plate fixed to its top end. A protruding plate is formed on the opposite side of each of the two rake plates, and a suction cup is installed on the opposite side of each protruding end. The four-way positioning component includes a counter-moving part mounted on the movable plate. A counter-moving plate that slides with the movable plate is fixed to the movable end of each counter-moving part. Multiple individual blocks are formed on the counter-moving plate, and an inner top is installed on each individual block. The movable plate is also equipped with multiple sets of counter-pushing parts, each with a clamping plate fixed to its pushing end.

[0005] Furthermore, the bidirectional pushing unit includes multiple pushing cylinders and multiple pairs of guide rods mounted on the movable plate. The piston rod of the pushing cylinder is fixed with a pushing plate that passes through the corresponding guide rod. A side pushing cylinder is mounted on the pushing plate, and the rake plate is fixed with the piston rod of the side pushing cylinder.

[0006] Furthermore, the displacement part is a two-way lead screw device, and the two displacement plates are respectively fixed to nuts on the two-way lead screw device.

[0007] Furthermore, the inner top is a displacement cylinder, and the piston rod of the displacement cylinder is fixed with a displacement block.

[0008] Furthermore, the pushing part includes multiple recesses, and a clamping cylinder is installed on the inner side of the recesses. The piston rod of the clamping cylinder is fixed with a clamping plate.

[0009] Furthermore, the punching assembly includes fixed platforms distributed on both sides of the movable plate. Multiple second lead screw devices are installed on the fixed platforms. The second lead screw devices are bidirectional and movable. A lifting plate that slides with the fixed platform is fixed between the nuts of the second lead screw devices in the same direction. A third lead screw device is installed on the lifting plate. A push plate that slides with the lifting plate is fixed to the nut end of the third lead screw device. A mounting seat is installed on the push plate. A punching cylinder is installed on the mounting seat. A punching head is installed at the top end of the punching cylinder.

[0010] Furthermore, an extension plate is fixed to the push plate.

[0011] Furthermore, the movable component is a first lead screw device, which is mounted on the wall and has its nut end connected to the top of the movable plate, and the movable plate is slidably connected to the wall.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] The punching device for the power distribution equipment cabinet door uses a moving component to move a moving plate closer to the door. The door-retrieving component uses a bidirectional pushing part to drive a rake plate and a suction cup to automatically grab, place, and position the door, eliminating the need for manual handling and positioning, thus reducing labor intensity. The opposing part drives the opposing plate to slide, and in conjunction with the inner top and the opposing pushing part, the door can be positioned from the inside and outside. The gap between the rake plates leaves a punching position. The moving component moves the moving plate to position the door between the punching components. After the door is positioned once, the punching process on both sides can be completed, eliminating the auxiliary time of disassembly and re-fixing, and significantly shortening the processing cycle of a single door.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-4 The punching device for the door of a power distribution equipment cabinet in this embodiment includes a movable plate 2 and a movable component located on top of the movable plate 2. The movable component is a first lead screw device 1, which is mounted on the wall and the nut end is connected to the top of the movable plate 2. The movable plate 2 is slidably connected to the wall. The movable plate 2 is driven to slide along the wall by the first lead screw device 1 to achieve position adjustment.

[0021] like Figure 2 A door-removing assembly is installed on the movable plate 2. The door-removing assembly includes two sets of bidirectional pushing parts. Each bidirectional pushing part includes two push cylinders 4 installed on the movable plate 2 and two pairs of guide rods 3 fixed below the corresponding push cylinders 4. The piston rod of the push cylinder 4 is fixed with a push plate 5 that passes through the corresponding guide rod 3. A side push cylinder 6 is installed on the surface of the push plate 5. The two sets of side push cylinders 6 are opposite to each other. The piston rod of the side push cylinder 6 is fixed with a rake plate 7. Three toothed plates are formed on the rake plate 7. A convex plate is formed on the opposite side of each toothed plate, and a toothed plate is fixed on the convex plate. The suction cup 8 above the plate moves the moving plate through the first screw device, bringing the rake plate closer to the box door until the box door is between the rake plates. The push cylinder 4 drives the push plate 5 to rise and fall along the guide rod 3, thereby adjusting the rake plate to a suitable position so that the convex plate is in contact with both sides of the box door. Then, the side push cylinder 6 drives the rake plate 7 to move horizontally to clamp the box door. Then, the push cylinder retracts, and the rake plate places the box door on the four-way positioning component. At the same time, the rake plate continues to clamp, and the suction cup 8 adheres to both sides of the box door, thereby achieving initial positioning and improving the stability of the box door's gripping and placement.

[0022] The movable plate 2 is also equipped with a four-way positioning assembly, which includes a shifting part and two pairs of pushing parts. The pushing part includes a pair of recesses 9 fixed on the movable plate 2 and distributed on the front and rear sides of the long side of the door. A clamping cylinder 10 is installed inside the recesses 9. The piston rod of the clamping cylinder 10 is fixed to a clamping plate 11. By pushing the clamping plate 11 with the clamping cylinder 10, the clamping and positioning is completed from the long side of the door, thereby achieving positioning in four directions and improving stability. The shifting part is a two-way screw device 12. Two nuts of the bidirectional screw device 12 are fixed with opposing plates 13 that slide with the moving plate 2. Three sets of blocks are formed on the surface of the opposing plates 13. Opposing cylinders 14 with their top ends facing outward are installed on the blocks. The piston rod of the opposing cylinder 14 is fixed with an opposing block. The two opposing plates 13 are driven to slide relative to each other or back to back by the bidirectional screw device 12. The opposing cylinders can be moved to a suitable position according to the size of the box door. The opposing cylinders 14 push the opposing blocks to achieve the positioning of the box door by pushing from the inside out in conjunction with the rake plate.

[0023] like Figure 1 and 3 Punching assemblies are distributed on the left and right sides of the movable plate 2. Each punching assembly includes a fixed platform 23 mounted on the ground. Two sets of second lead screw devices 15 are mounted on the fixed platform 23. The second lead screw devices 15 are bidirectionally movable. A lifting plate 16, slidably connected to the fixed platform 23, is fixed between the nuts of the second lead screw devices 15 that move in the same direction. The second lead screw devices 15 can drive the two sets of lifting plates 16 to move in opposite or opposite directions, thereby adjusting the punching position. A third lead screw device 17 is mounted on the lifting plate 16. A push plate 18, slidably connected to the lifting plate 16, is fixed to the nut end of the third lead screw device 17. The operation of the third lead screw device can adjust the punching position according to the single hole being punched. The dual-hole adjustable lifting plate can move individually or both sets of lifting plates can move simultaneously. An extension plate 22 is fixed on the push plate 18. When the push plate is pushed forward, the extension plate is pressed against the moving plate, which can play a limiting role and also position the moving plate. A mounting base 19 is installed on the push plate 18. A punching cylinder 20 is installed on the opposite side of the mounting base 19. The piston rod of the punching cylinder 20 is fixed with a punching head 21. When the push plate is adjusted to a suitable position, the punching cylinder drives the punching head to push out, so that it can pass through the gap of the rake plate and punch the door between the moving cylinders. At the same time, it also completes the punching of both sides to improve efficiency.

[0024] The working principle of this embodiment is as follows:

[0025] The first lead screw mechanism moves the moving plate, positioning the box door between the rake plates. The push cylinder drives the push plate to move, bringing the rake plate's protrusion into contact with the box door. The side push cylinder drives the two rake plates to move relative to each other, bringing the suction cup into contact with the box door. The suction cup then draws air to adhere the box door. Subsequently, the first lead screw mechanism resets, positioning the box door between the punching heads. Simultaneously, the push cylinder operates, moving the rake plates via the push plate, thus placing the box door onto the four-way positioning assembly for initial positioning. The clamping push cylinder then pushes the clamping push plate towards the long side of the box door. The first step involves clamping the door from top to bottom to achieve precise positioning in all four directions. Then, a two-way screw device drives two opposing plates to slide relative to or away from each other, moving the opposing cylinder until the top end is in contact with the inner side of the short side of the door. The opposing cylinder pushes the opposing block to position the door from the inside in conjunction with the rake plate. The second screw device adjusts the position of the lifting plate so that the punch head corresponds to the punching position. The third screw device adjusts the position of the push plate so that the punch head is aligned with the punching position on the door. The punching cylinder drives the punching head to complete the punching.

[0026] Therefore, the above operations can be automated by picking up the door, placing and positioning it, and punching and cutting it, thereby effectively improving the processing efficiency.

[0027] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
