Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and specifically to an electrical protection device for CNC machine tools. Background Technology

[0002] CNC machine tools are numerically controlled machine tools, a type of automated machine tool equipped with a program control system. This control system logically processes programs with control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. After processing, the CNC device sends various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. Because CNC machine tools have many electrical components, they often require electrical protection devices for protection.

[0003] Currently, when CNC machine tools are in use, components such as transformers, frequency converters, relays, and switches are mainly housed in electrical cabinets. The existing electrical cabinets are mainly controlled by manual unlocking, which is not only cumbersome and inconvenient to operate, but also has poor safety, low automation, and poor performance.

By setting two symmetrical baffles, and with the cooperation of structures such as a sliding cavity, a movable block, and a bidirectional screw, the movable block can drive the two baffles to move towards or away from each other. By controlling the two baffles to move away from each other, the cabinet can be opened quickly, and vice versa, the cabinet can be closed quickly. The operation is simple and convenient, and the automation and safety are high, which greatly improves the effectiveness of the electrical protection device and solves the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical protection device for CNC machine tools, comprising:

[0006] The cabinet has fixed protrusions at both ends on one side, and two baffles are symmetrically installed between the two fixed protrusions.

A slider is slidably connected inside the slide rail. A fixing component is provided between the slider and the fixed bracket. One end of the slider extends outside the slide rail and is connected to a card plate. A connecting arm is fixed to one end of the card plate. A support frame is connected between the two connecting arms and the ends of the card plate.

[0008] Preferably, the fixing component includes a plurality of threaded grooves arrayed on one side of the fixing frame, a fixing knob screwed into the threaded grooves, and a positioning hole matching the fixing knob at one end of the slider.

[0009] Preferably, the interior of the sliding cavity is rotatably connected to a bidirectional screw via a bearing. One end of the bidirectional screw extends outside the sliding cavity and is equipped with a drive motor. The two movable blocks are respectively screwed onto the two ends of the bidirectional screw via threads.

[0010] Preferably, the drive motor is provided with a protective cover, and a reinforcing frame is fixed between the protective cover and the fixed boss.

[0011] Preferably, both baffles have observation windows on their side walls, and a snap-fit ​​assembly is provided between the two baffles.

[0027] This utility model provides, for example Figures 1-5 An electrical protection device for a CNC machine tool, as shown, includes:

[0028] Cabinet 1, with fixed protrusions 2 at both ends of one side of cabinet 1, and two baffles 3 symmetrically installed between the two fixed protrusions 2. A sliding cavity 5 is opened on the top side of one of the fixed protrusions 2 near the bottom of the baffle 3. Movable blocks 7 are symmetrically arranged at both ends inside the sliding cavity 5. The tops of the two movable blocks 7 extend outside the sliding cavity 5 and are fixedly connected to the two baffles 3 respectively.

[0029] Inside the sliding cavity 5, a bidirectional screw 6 is rotatably connected via a bearing. One end of the bidirectional screw 6 extends outside the sliding cavity 5 and is equipped with a drive motor 8. Two movable blocks 7 are screwed onto both ends of the bidirectional screw 6 respectively.

[0030] In use, the drive motor 8 can be started, which drives the bidirectional screw 6 to rotate. Then, the bidirectional screw 6 can drive the two movable blocks 7 to move towards or away from each other in the sliding cavity 5. The movable blocks 7 drive the baffles 3 to move, so that the two baffles 3 can move closer or further away from each other. By controlling the two baffles 3 to move away from each other, the cabinet 1 can be opened quickly, and vice versa, the cabinet 1 can be closed quickly. The operation is simple and convenient, and the automation and safety are high, which greatly improves the effectiveness of the electrical protection device.

[0031] The drive motor 8 is provided with a protective cover 9, and a reinforcing frame is fixed between the protective cover 9 and the fixed boss 2. Based on this, the drive motor 8 can be protected by the protective cover 9, and the reinforcing frame can greatly enhance the structural strength.

[0032] Both baffles 3 have observation windows 4 on their side walls, and a snap-fit ​​assembly is provided between the two baffles 3. The observation windows 4 allow for easy observation of the operation of the electrical components inside the cabinet 1.

[0033] The snap-fit ​​assembly includes a snap-fit ​​strip 19 disposed on one side of one of the baffles 3, and a snap-fit ​​groove 20 matching the snap-fit ​​strip 19 is provided on one side of the other baffle 3.

[0034] Based on this, by interlocking the clip 19 and the slot 20, the two baffles 3 can be joined together more tightly and securely, resulting in better performance.

[0035] Two fixed brackets 10 are symmetrically fixed on both sides of the inside of the cabinet 1. The side wall of the fixed bracket 10 is provided with a slide rail. A slider 14 is slidably connected inside the slide rail. A fixing component is provided between the slider 14 and the fixed bracket 10. One end of the slider 14 extends outside the slide rail and is connected to a card plate 12. One end of the card plate 12 is fixed with a connecting arm 11. A support frame 13 is connected between the two connecting arms 11 and the end of the card plate 12.

[0036] The side wall of the support frame 13 has multiple mounting holes 18.

[0037] The fixing component includes multiple threaded grooves 16 arrayed on one side of the fixing frame 10, with a fixing knob 15 screwed into the threaded grooves 16, and a positioning hole 17 matching the fixing knob 15 at one end of the slider 14.

[0038] The support frame 13 facilitates the fixed installation of electrical components. In use, the card plate 12 can be pulled along the fixed frame 10 to move the slider 14 in the slide rail. This allows the connecting arm 11 to drive the support frame 13 to move up and down between the two fixed frames 10. By turning the fixing knob 15, the fixing knob 15 can be rotated in the corresponding threaded groove 16 and inserted into the positioning hole 17 to lock and fix the slider 14. The distance between the two adjacent sets of support frames 13 can be adjusted as needed to better assemble electrical components.
