Description

Technical Field

[0001] The invention belongs to the technical field of high and low voltage distribution cabinet production equipment, and particularly relates to automatic cutting equipment for high and low voltage distribution cabinet production. Background Art

[0002] High and low voltage distribution cabinets are power distribution equipment used for power distribution, control, metering, and cable connection within power supply systems. Power supply bureaus and substations typically use high-voltage switchgear. The voltage is then stepped down by a transformer and led to a low-voltage distribution cabinet. The low-voltage distribution cabinet then leads to the various power distribution panels, control boxes, and switch boxes that consume electricity. These cabinets integrate switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, and other protective devices to achieve the desired functionality. High and low voltage distribution cabinets require laser cutting equipment to cut sheet metal into the appropriate specifications, which are then assembled into the cabinet body using bolts or welding.

[0003] When existing automatic cutting equipment for the production of high and low voltage distribution cabinets cuts plates and tightens the cut plates, most of the time the cutting is performed by rotating the screw to press the fastening plate onto the plate. After the cutting is completed, the screw is rotated in the opposite direction to loosen the fastening plate from the plate. Repeatedly rotating the screw is not only labor-intensive, but also affects the cutting efficiency of the plate, thereby reducing the production efficiency of the high and low voltage distribution cabinets.

[0051] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Reference Figure 1 An embodiment of the present invention proposes an automatic cutting device for the production of high and low voltage distribution cabinets, comprising a lower bracket 1, the upper end of the lower bracket 1 is fixedly connected to the upper bracket 2, a plate fastener 3 is installed at the upper end of the lower bracket 1 and below the upper bracket 2, a movable module 4 is installed on the upper bracket 2, and a laser cutting head 5 is installed on the movable module 4.

[0053] The plate is sucked tight by the plate fastener 3 to achieve the purpose of fastening the plate, thereby ensuring the cutting efficiency of the plate and improving the production efficiency of the high and low voltage distribution cabinet. It is very convenient to use. Then the laser cutting head 5 is pulled by the mobile module 4 to change, and the changed laser cutting head 5 cuts the plate.

[0054] Reference Figure 2-Figure 4The plate fastener 3 includes a rotating unit 31, which is used to pull the plate to rotate, so that the laser cutting head 5 can cut the plate.

[0055] The rotating unit 31 includes a pair of supporting plates 311, and the supporting plates 311 are used to support the rotating unit 31;

[0056] A pair of carrier plates 311 are screwed onto a rotating rod 314. A carrier seat 312 is mounted on the outer side of one of the carrier plates 311. A motor 313 is fixed to the carrier seat 312. The rotating portion of the motor 313 is connected to one end of the rotating rod 314. The motor 313 then pulls the rotating rod 314 to rotate.

[0057] The rotating rod 314 is fixedly connected to the rotating frame 315. The rotating frame 315 can rotate along with the rotating rod 314, thereby adjusting the inclination angle of the plate fastened to the rotating frame 315 to ensure that the plate can be beveled.

[0058] Reference Figure 2 、 Figure 3 and Figure 5 The rotating frame 315 is provided with a changing unit 34, which is used to change the orientation of the plate, thereby allowing the plate to be moved to a designated area;

[0059] The movable unit 34 includes a first support platform 341 fixedly connected to one end of the rotating frame 315 and a second support platform 347 fixedly connected to the other end of the rotating frame 315. The second support platform 347 and the first support platform 341 are arranged along the axis of the rotating rod 1 314.

[0060] The first carrier 341 is fixedly connected to the second motor 342. The rotating portion of the second motor 342 is fixedly connected to the threaded rod 343. The threaded rod 343 is screwed onto the first carrier 341 and the second carrier 347. Then, the second motor 342 can pull the threaded rod 343 to rotate.

[0061] The threaded rod 343 is connected to a threaded sleeve 345, which is fixedly connected to a square piece 348. A guide column 344 is fixedly connected between the first supporting platform 341 and the second supporting platform 347. A hoop 346 is movably mounted on the guide column 344. The hoop 346 is fixedly connected to the square piece 348. When the threaded rod 343 rotates, the threaded sleeve 345 can be pulled to rotate, thereby pulling the square piece 348 along the axial direction of the threaded rod 343 to adjust the orientation of the square piece 348.

[0062] Reference Figure 2 and Figure 3 , a fastening unit 32 is mounted on the square piece 348, and the fastening unit 32 is used to fasten the plate;

[0063] Reference Figure 6 and Figure 7 The fastening unit 32 includes two pairs of hydraulic rods 324 fixed to the square plate 348. The movable parts of the hydraulic rods 324 are fixed to the rectangular platform 321. The rectangular platform 321 is attached to the plate. The rectangular platform 321 can be vertically moved under the traction of the hydraulic rods 324, and is located in the upper area and the lower area respectively.

[0064] The top of the square piece 348 is fixedly connected to the second carrier piece 329, and the second carrier piece 329 is fixedly connected to a pair of air covers 326. The air covers 326 are connected to a plurality of air pumps 327, and the mouths of the air pumps 327 are arranged toward the lower wall of the rectangular platform 321.

[0065] Reference Figure 8 and Figure 9 A circular groove 3211 matching the vacuum cylinder 327 is reserved on the lower wall of the rectangular platform 321. The outer diameter of the vacuum cylinder 327 is smaller than the inner diameter of the circular groove 3211. Then, when the rectangular platform 321 is in the lower area, the vacuum cylinder 327 can extend into the circular groove 3211. At this time, the periphery of the vacuum cylinder 327 is blocked by the wall of the circular groove 3211.

[0066] A through slot 3212 is reserved on the wall of the circular groove 3211 and passes through the rectangular platform 321, so that air can flow from the vacuum cylinder 327 to the through slot 3212;

[0067] Reference Figure 6 and Figure 7 The square piece 348 is fixedly connected to the vacuum pump 325, and the vacuum pump 325 is connected to the air hood 326. Then the vacuum pump 325 draws air to reduce the air pressure and the air can pass through the air hood 326, the vacuum cylinder 327 and the through groove 3212 to the upper wall of the rectangular table 321, and then the plate on the rectangular table 321 is sucked tightly.

[0068] A restraining rod 322 is installed on the upper wall of the rectangular table 321 to restrain the right angles of the plate, so that the plate can be accurately tightened and cut. With the cooperation of the rotating unit 31, the plate can be tilted, and the waste falling in the area of the restraining rod 322 can slide down by itself when the plate is tilted.

[0069] Reference Figure 6 and Figure 7A switch 328 is installed on the passage connecting the vacuum pump 325 and the air hood 326. A handle 3281 for turning the switch 328 on or off is installed on the switch 328. A movable column 323 is installed on the lower wall of the rectangular platform 321. The movable column 323 and the handle 3281 cooperate with each other. Then, when the rectangular platform 321 moves to the lower area, the movable column 323 can touch the handle 3281, and the handle 3281 rotates, thereby opening the passage connecting the vacuum pump 325 and the air hood 326. At this time, the vacuum cylinder 327 is just located inside the circular groove 3211, allowing the vacuum pump 325 to perform vacuuming to tighten the plate.

[0070] A spiral beryllium copper wire is installed between the handle 3281 and the switch 328. When the rectangular table 321 is in the upper area, the movable column 323 and the handle 3281 are separated, and the handle 3281 can be rotated back to its original position with the cooperation of the spiral beryllium copper wire, and then the channel connecting the vacuum pump 325 and the air cover 326 is closed. At this time, the vacuum cylinder 327 and the circular groove 3211 are separated, and then the vacuum pump 325 cannot perform vacuuming, and then the plate is loosened.

[0071] Reference Figure 4 A plurality of unloading chutes 316 are reserved on the rotating frame 315. The unloading chutes 316 are used to unload waste materials generated during cutting to ensure continuous cutting of the plate.

[0072] As the plate is continuously cut, waste material will adhere to the surface of the rectangular platform 321. If the waste material is not removed in time, it will not only be detrimental to the subsequent cutting of the plate, but will also cause the through groove 3212 to be blocked, thereby weakening the fastening effect on the plate.

[0073] Reference Figure 2 A cleaning unit 33 is mounted on the rotating frame 315. The cleaning unit 33 is used to remove waste from the wall surface of the rectangular table 321. When the rectangular table 321 is located in an area far from the second motor 342, the plate is located in the cutting area and the cutting process is performed. When the rectangular table 321 is pulled by the moving unit 34 and gradually approaches the second motor 342, the plate is located in the waste removal area and the waste on the wall surface is swept away by the cleaning unit 33.

[0074] Reference Figure 2 and Figure 10-12The decontamination unit 33 includes a pair of supports 331 fixedly connected to the rotating frame 315. A second rotating rod 332 is fixedly connected between the pair of supports 331, and a rotating column 335 is screwed onto the second rotating rod 332. The rotating column 335 can then rotate around the second rotating rod 332 on the pair of supports 331, and the lower wall of the rotating column 335 is in contact with the upper wall of the rectangular platform 321 when it is raised. When the rectangular platform 321 approaches the rotating column 335, the waste material contacts the wall of the rectangular platform 321 through the rotating column 335, and is then removed and falls into the discharge chute 316.

[0075] The second rotating rod 332 is fixedly connected to a housing 333, which is located above the rotating column 335. One side of the housing 333 is fixedly connected to a collecting cover 334, which is located on the side of the rotating column 335 close to the fastening unit 32 and is used to collect waste attached to the wall of the rotating column 335.

[0076] A U-shaped groove 3331 is provided on the housing 333. A cleaning sheet 3341 is mounted on the collecting cover 334, facing one side of the U-shaped groove 3331. One side of the cleaning sheet 3341 abuts against the wall of the rotating column 335. As the rectangular platform 321 approaches the rotating column 335, the cleaning sheet 3341 continuously abuts against the wall of the rotating column 335, removing waste material adhering to the wall of the rotating column 335.

[0077] An inclined wall is provided on the cleaning sheet 3341 toward the side close to the collecting cover 334 , and the inclined wall is inclined downward toward the side of the collecting cover 334 , so that the waste shoveled off by the cleaning sheet 3341 falls into the collecting cover 334 along the inclined wall.

[0078] Since the collecting cover 334 is only installed on one side of the housing 333, the waste on the wall cannot be removed when the rotating column 335 rotates in the reverse direction, which results in the waste on the rotating column 335 being unable to be removed;

[0079] Reference Figure 11 and Figure 12 The side wall of the rotating column 335 is fixedly connected to the rotating rod 3310, the rotating rod 3310 is hoop-connected to the rotating rod 2 332, and the outer circumference of the rotating rod 3310 is fixedly connected to the rotating disk 336, and the outer circumference of the rotating disk 336 is reserved with a plurality of skewed teeth;

[0080] The housing 333 is fixedly connected to a connecting post 339, which is screwed onto a retaining bar 337. The retaining bar 337 cooperates with the teeth on the rotating disk 336. A spiral beryllium copper wire 338 is fixed between the connecting post 339 and the retaining bar 337 to facilitate the return of the retaining bar 337.

[0081] When the rectangular platform 321 moves toward the side of the rotating column 335, the rotating column 335 performs a cleaning operation, causing a large amount of waste material adhering to the wall surface to be removed by the cleaning sheet 3341, which is in contact with the wall surface of the rotating column 335. The waste material on the wall surface of the rotating column 335 is then removed into the collecting cover 334, thereby ensuring that the wall surface of the rotating column 335 is clean.

[0082] Because the rotating post 335 continues to rotate under the obstruction of the rectangular platform 321, the rotating disk 336 rotates along with the rotating post 335. The clamping bar 337 does not restrict the rotation of the rotating disk 336 at this time.

[0083] When the rectangular table 321 moves toward the side farther from the rotating post 335, the rotating post 335 rotates in the reverse direction. At this time, the rotating disk 336, in cooperation with the clamping bar 337, cannot rotate in the reverse direction, and the rotating post 335 cannot rotate. At this time, the area where the rotating post 335 and the wall of the rectangular table 321 are in contact is always the same, thereby preventing waste from adhering to the rectangular table 321 during the return period.

[0084] Reference Figure 11 and Figure 12 The rotating column 335 is provided with a plurality of protrusions 3351, which are arranged at equal intervals. A U-shaped opening 3352 is reserved between a pair of adjacent protrusions 3351, and the U-shaped opening 3352 and the teeth on the rotating disk 336 are matched with each other one to one. When the rotating disk 336 is constrained, the U-shaped opening 3352 is located at the lower end of the rotating column 335. When the rotating column 335 returns to its original position, the lower end of the rotating column 335 is separated from the wall of the rectangular platform 321, thereby effectively preventing waste from adhering to the rectangular platform 321.

[0085] The decontamination sheet 3341 is made of TPE material, ensuring that when the decontamination sheet 3341 reaches the area of the protrusion 3351 and the U-shaped opening 3352, all waste materials attached to the protrusion 3351 and the U-shaped opening 3352 can be removed.

[0086] Reference Figure 1 The movable module 4 includes a transverse slide rail 41 fixedly connected to the upper bracket 2, the slider on the transverse slide rail 41 is fixedly connected to the longitudinal slide rail 42, the slider on the longitudinal slide rail 42 is fixedly connected to the L-shaped plate 43, and the L-shaped plate 43 is connected to the laser cutting head 5.

[0087] The slider on the transverse slide rail 41 pulls the longitudinal slide rail 42 to move, and the slider on the longitudinal slide rail 42 pulls the L-shaped plate 43 to move. Therefore, the L-shaped plate 43 pulls the laser cutting head 5 to achieve the purpose of cutting the plate.
