Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet manufacturing technology, specifically to a cutting device for the G-shaped crossbeam of an electrical cabinet. Background Technology

[0002] Electrical cabinets (distribution cabinets / control cabinets) are complete sets of devices used for power distribution, circuit protection, and equipment control. They typically consist of a cabinet body, electrical components (circuit breakers, transformers, etc.), and internal support structures. The G-type beam, through its optimized frame structure, solves the problems of insufficient strength, complex installation, and high cost associated with traditional cabinets. The combination of these two features ensures cabinet stability while improving manufacturing efficiency and economy. During the G-type beam manufacturing process, a cutting device is used to cut the sheet metal, and after bending, the beam is further cut to the required length to meet the requirements of the electrical cabinet.

[0003] For example, application number CN202023149010.1, with authorization announcement date 20210907, describes a cutting mechanism for a G-type beam flying cutter. This mechanism includes a mounting gantry rod. The outer surface of the front end of the mounting gantry rod is provided with an anti-loosening mechanism and a fixing mechanism. The anti-loosening mechanism is located on one side of the fixing mechanism. The upper outer surface of the mounting gantry rod is provided with a first reinforcing bolt post and a second reinforcing bolt post. The first reinforcing bolt post is located on one side of the second reinforcing bolt post. The upper outer surface of the first reinforcing bolt post is provided with a top plate, and one outer surface of the first reinforcing bolt post is provided with a base. The fixing mechanism includes a fixing plate, a compression stud, a mounting threaded post, a fixing post, a mounting nut, and a mounting seat. This cutting mechanism for a G-type beam flying cutter, as described in this utility model, facilitates cutting with the beam flying cutter while adding an anti-loosening device to prevent loosening, and also enhances the fixation of the cutting mechanism, thus bringing better application prospects.

[0004] Replacing the cutting saw blade in a traditional G-type beam cutting mechanism requires the complete disassembly of the drive shaft assembly, which is time-consuming and affects positioning accuracy. Therefore, there is an urgent need to design a cutting device for the G-type beam of an electrical cabinet to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for the G-type crossbeam of an electrical cabinet, so as to solve the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cutting device for a G-type beam of an electrical cabinet includes a frame assembly, a clamping assembly, and a cutting assembly. The clamping assembly is slidably mounted on the outer wall of the top side of the frame assembly. The cutting assembly is mounted on the frame assembly and includes a lifting cylinder. The output end of the lifting cylinder is bolted to a mounting base, and a support plate is welded to the outer wall of the bottom side of the mounting base. A drive motor is bolted to the outer wall of the support plate. A sliding groove is formed on the outer wall of the mounting base.

A sliding plate is slidably connected inside the sliding groove, and a limit cylinder is mounted on the outer wall of the sliding plate via a bearing. The sliding plate and one end of the adjusting screw are threadedly connected. A key shaft is mounted on the outer wall of the support plate via a bearing, and one end of the key shaft is mounted to the output end of the drive motor via a coupling. One end of the key shaft is slidably inserted into the limit cylinder. A cutting saw blade is sleeved on the outside of the key shaft, and the cutting saw blade is located between the support plate and the sliding plate.

[0008] Furthermore, the frame assembly includes a support platform, a mounting bracket is bolted to one outer wall of the top of the support platform, the lifting cylinder is bolted to the inside of the mounting bracket, and pads are bolted to both outer walls of the top of the support platform.

[0009] Furthermore, an installation groove is provided on one side of the outer wall of the top of the support platform, and a transmission screw is installed inside the installation groove through a bearing. A travel motor is installed on one side of the outer wall of the support platform through bolts, and the output end of the travel motor is installed together with one end of the transmission screw through a coupling.

[0010] Furthermore, each of the two outer walls on the top of the support platform is provided with a mounting groove and a recess, and the cutting saw blade is inserted into the recess when it is raised and lowered for cutting. A limiting component is provided inside the mounting groove.

[0011] Furthermore, the limiting assembly includes an adjusting motor, left and right rotating lead screws, and clamping plates. The left and right rotating lead screws are installed inside the mounting groove via bearings. The two clamping plates are threaded onto both ends of the left and right rotating lead screws. The adjusting motor is installed on the outer wall of one side of the support platform via bolts. The output end of the adjusting motor is connected to one end of the left and right rotating lead screws via a coupling.

[0012] Furthermore, the clamping assembly includes a slide block, which is slidably connected inside the mounting groove. The slide block is threadedly connected to the transmission lead screw.

[0014] In the above technical solution, the cutting device for the G-type crossbeam of the electrical cabinet provided by this utility model has the following advantages:

[0015] (1) This utility model drives the sliding plate to slide in the groove by adjusting the screw, so as to realize the flexible adjustment of the distance between the cutting saw blade and the support plate. Furthermore, the key shaft and the limit cylinder plug-in structure can eliminate the need to disassemble the drive motor or the overall transmission shaft assembly when replacing the saw blade, which significantly shortens the maintenance time and avoids the loss of positioning accuracy caused by repeated disassembly and assembly. This solves the core problem of the cumbersome operation of replacing saw blades in traditional cutting mechanisms.

[0016] (2) The limiting component of this utility model adopts a left and right rotating screw to drive a symmetrical clamping plate. Combined with the precise alignment design of the cutting saw blade and the groove, the crossbeam can be automatically centered and fixed simultaneously during the cutting process. This design effectively solves the positioning deviation problem caused by manual adjustment of traditional clamping devices, and is especially suitable for batch processing scenarios.

[0017] (3) The transmission screw in the frame assembly of this utility model is driven by a traveling motor and forms a precision screw-nut pair with the slide of the clamping assembly that is slidably set in the mounting groove. This design realizes the automated and linear feeding of the G-type crossbeam to be cut. Compared with manual push-pull positioning, the screw drive has high rigidity and low backlash characteristics, which can ensure that the crossbeam moves smoothly and accurately along the preset path during the cutting process, effectively preventing deviation or shaking. It not only improves the accuracy of single cutting, but also provides a guarantee for the dimensional consistency of continuous batch cutting. At the same time, the motor-driven feeding speed is fast and controllable, which significantly improves the overall cutting efficiency.

[0018] (4) The clamping assembly of this utility model achieves a dual mode of flexible clamping and rigid locking of the crossbeam by means of linkage control of the limiting airbag and hydraulic oil, and by adjusting the piston plate pressure by the screw motor. This can avoid damage to the workpiece surface and resist cutting vibration, significantly improving the cutting end face quality of the long G-type crossbeam. Attached Figure Description

[0030] Specifically, in this embodiment, the assembly includes a frame assembly 1, a clamping assembly 2, and a cutting assembly 3. The clamping assembly 2 is slidably disposed on the outer wall of the top side of the frame assembly 1. The cutting assembly 3 is disposed on the frame assembly 1 and includes a lifting cylinder 23.

A drive motor 31 is bolted to the outer wall of the support plate 25, and the drive motor 31 drives the saw blade to rotate at high speed via a key shaft 29. A groove 32 is formed on the outer wall of the mounting base 24, and an adjusting screw 30 is mounted on the outer wall of the mounting base 24 via a bearing. The adjusting screw 30 can be adjusted manually or electrically, driving the sliding plate 27 to slide within the groove 32, changing the distance between the saw blade and the support plate 25 to accommodate beams of different thicknesses.

Furthermore, the plug-in structure of the key shaft 29 and the limiting cylinder 28 allows the drive motor 31 or the entire transmission shaft assembly to be replaced without disassembling the saw blade, significantly shortening maintenance time and avoiding the loss of positioning accuracy caused by repeated disassembly and assembly. This solves the core problem of the cumbersome operation of replacing saw blades in traditional cutting mechanisms.

The recess 11 is aligned with the vertical path of the cutting saw blade 26 to ensure cutting position accuracy. When the cutting saw blade 26 is raised and lowered for cutting, it is inserted into the recess 11. The placement groove 12 contains... Limiting component 10; The limiting component 10 includes an adjusting motor 13, left and right rotating lead screws 14, and clamping plates 15. After the crossbeam reaches the cutting station, the adjusting motor 13 drives the left and right rotating lead screws 14 to rotate, causing the symmetrical clamping plates 15 to move synchronously towards each other, automatically centering and fixing the crossbeam directly above the groove 11. The left and right rotating lead screws 14 are installed inside the mounting groove 12 through bearings, and the two clamping plates 15 are threaded onto both ends of the left and right rotating lead screws 14. The adjusting motor 13 is installed by bolts. On one side of the outer wall of the support platform 4, the output end of the adjusting motor 13 is connected to one end of the left and right turning screw 14 via a coupling; the clamping assembly 2 includes a slide 16, which is slidably connected inside the mounting groove 5. The slide 16 and the transmission screw 6 are connected by a thread. A limiting cavity 17 is opened on one side of the outer wall of the slide 16, and a limiting airbag 18 is installed on the inner wall of the limiting cavity 17 by bolts. The limiting airbag 18 achieves flexible clamping by the pressure change of the hydraulic oil 22 in the oil tank 19.

[0043] The lead screw motor 20 drives the piston plate 21 to change the oil pressure.

[0044] Under low pressure, the airbag deforms to adapt to the workpiece surface.

[0045] Rigid clamping is formed under high pressure;

[0046] An oil reservoir 19 is bolted to the outer wall of one side of the top of the slide block 16. The oil reservoir 19 is connected to the limiting airbag 18 through a pipe. A piston plate 21 is slidably inserted inside the oil reservoir 19. The oil reservoir 19 stores hydraulic oil 22. A screw motor 20 is bolted to the center of the top of the oil reservoir 19. When the screw motor 20 is started, it drives the piston plate 21 to press down inside the oil reservoir 19, injecting the hydraulic oil 22 into the limiting airbag 18, causing it to expand and flexibly clamp the G-shaped crossbeam. The output end of the screw motor 20 is threadedly connected to the piston plate 21.

[0047] Working principle: The operator places the G-type crossbeam on the pad 8 of the support platform 4, with one end of the crossbeam inserted into the limiting cavity 17 of the clamping assembly 2. Then, the screw motor 20 is started, driving the piston plate 21, which is threaded to its output end, to press down within the oil reservoir 19. The piston plate 21 compresses the hydraulic oil 22, which is then injected into the limiting airbag 18 through a pipeline. The limiting airbag 18 expands and deforms, flexibly covering and pressing the end of the crossbeam, achieving non-destructive clamping. Afterwards, the traveling motor 7 is started, and the traveling motor 7... The shaft drives the transmission screw 6 to rotate within the mounting groove 5. The slide 16, due to its threaded connection with the transmission screw 6, moves linearly along the mounting groove 5, precisely conveying the clamped crossbeam towards the cutting assembly 3. Subsequently, when the crossbeam reaches the preset cutting position above the corresponding groove 11, the adjusting motor 13 starts, driving the left and right rotating screws 14 to rotate within the placement groove 12 via the coupling. The two clamping plates 15, due to their oppositely oriented threads, move synchronously towards each other on the left and right rotating screws 14, applying balanced force from both sides of the crossbeam. The clamping force completes automatic centering and rigid fixation, eliminating offset caused by cutting vibration. Then, the drive motor 31 starts, driving the key shaft 29 to rotate at high speed via the coupling. Simultaneously, the lifting cylinder 23 pushes the mounting base 24 downwards, causing the cutting saw blade 26 fixed on the key shaft 29 to descend synchronously. The saw blade 26 cuts into the crossbeam and finally embeds into the groove 11. The depth of this process is ensured by the cylinder stroke and the groove depth. The rotating saw blade completes the cutting. During cutting, the sliding end of the key shaft 29 is always inserted into the limiting sleeve 28 of the sliding plate 27. Ensure the radial stability of the saw blade; after cutting ends, a. the lifting cylinder 23 retracts, driving the saw blade 26 to rise and detach from the workpiece, the clamping plate 15 and the limiting airbag 18 are released from clamping, the travel motor 7 reverses, and the slide 16 returns to the starting position; when the saw blade is replaced later, turn the adjusting screw 30, the adjusting screw 30 drives the sliding plate 27 threaded to it to move outward along the slide groove 32, increasing the distance with the support plate 25, one end of the key shaft 29 slides out from the limiting cylinder 28, and the cutting saw blade 26 can be directly replaced along the key shaft axis without disassembling the drive motor 31 or the key shaft 29.
