Description

Technical Field

[0001] This utility model relates to the field of machine tool protection technology, specifically a CNC machine tool protection device. Background Technology

[0002] CNC machine tools are automated machine tools equipped with a program control system. They can automatically execute machine tool actions and process parts according to a pre-written program. While improving machining accuracy and accelerating the machining process, CNC machine tool operation will generate high-temperature chips that fly out, and there may even be dangerous situations where the grinding wheel or cutting tool is damaged and flies out at high speed. These hidden dangers pose a serious threat to operators. Therefore, it is necessary to equip them with corresponding protective devices to ensure the safety of the production process.

[0003] An investigation revealed that a Chinese utility model patent discloses a novel CNC machine tool protective device (publication number: CN222021202U), comprising a device housing, one side of which is a sealed whole and the other side is open. Two main connectors are fixedly connected to one end of the device housing with mounting holes. A cleaning groove is provided at the bottom of the same side of the device housing with the main connectors, and a sealing device is provided on the outside of the cleaning groove. A mounting plate is fixedly connected to the side of the device housing away from the sealing device. Two mounting holes are provided at the end of the mounting plate near the main connectors. An operation panel is provided on the side of the mounting plate away from the sealing device. Bulletproof glass is fixedly installed on the device housing above the mounting plate.

[0004] In the aforementioned patent, by removing the fixing bolts and opening the baffle along the hinge, and since the cleaning groove is lower than the inner bottom surface of the device housing, the waste accumulated on the bottom of the device housing can be directly swept away from the cleaning groove using a broom. This solves the problem that existing devices are difficult to clean internal waste because they do not have a dedicated outlet for waste such as debris and dust. However, each time the connecting plate and baffle are opened or installed, multiple fixing bolts need to be rotated, making the operation process cumbersome and reducing the overall work efficiency.

[0005] Therefore, this utility model provides a protective device for CNC machine tools to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This utility model provides a protective device for CNC machine tools, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0013] As a preferred technical solution of this application, a movable frame is slidably connected inside the housing of the device via the slide rail, and a processing blade is fixedly connected to the top of the movable frame.

[0014] As a preferred technical solution of this application, a bulletproof glass is fixedly connected to one side of the device housing, and a fixing frame is fixedly connected to the inner wall of the device housing near the bulletproof glass.

[0015] As a preferred technical solution of this application, the fixed frame has an installation groove inside, and tempered glass is slidably connected inside the installation groove. Both the bulletproof glass and the tempered glass are inclined.

[0016] (III) Beneficial Effects

[0017] This utility model has a simple structure and is easy to use. With the setting of the loading and unloading mechanism, when fixing the baffle, you only need to align the fixing block between the two locking blocks and press it directly to fix it. When disassembling, push the pressing block outward, which will drive the moving rod to move synchronously, thereby causing the control block to move. The moving rod drives the sliding rod to slide in the sliding groove. The sliding rod pushes the inclined block, and the inclined block then drives the locking block to slide on the side surface of the limit rod until the fixing block is completely separated from the two locking blocks, thus completing the disassembly. The whole operation process is simple and quick, effectively improving the overall work efficiency. Attached Figure Description

[0026] 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.

[0027] This utility model provides a protective device for CNC machine tools, such as... Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the CNC machine tool protective device includes a device housing 1, an installation baffle 2 disposed on one side of the device housing 1, fixing blocks 3 fixedly installed on both sides of the installation baffle 2, a limit box 4 fixedly installed on both sides of the device housing 1, and a loading and unloading mechanism disposed inside the limit box 4 for quick installation and removal of the installation baffle 2.

[0028] The loading and unloading mechanism includes a limiting rod 5 fixedly installed inside the limiting box 4, a locking block 6 slidably installed on the side surface of the limiting rod 5, an inclined block 7 fixedly installed on one side of the locking block 6, a spring 8 sleeved on the side surface of the limiting rod 5, a moving rod 9 slidably installed inside the limiting box 4, a control block 10 fixedly installed on one end of the moving rod 9, a slide rod 11 fixedly installed on one side of the control block 10, and a pressing block 12 fixedly installed on the other end of the moving rod 9.

[0029] One end of the spring 8 is fixedly connected to one side of the locking block 6, and the other end of the spring 8 is fixedly connected to the inner wall of one side of the limiting box 4. The moving rod 9 passes through the limiting box 4, and the inner wall of the inclined block 7 is provided with a sliding groove for the sliding rod 11 to slide.

[0030] When using this CNC machine tool protective device, first place the outer casing 1 in a suitable position. When it is necessary to remove the mounting baffle 2 to clean the inside of the outer casing 1, push the pressing block 12 outward. The movement of the pressing block 12 will drive the moving rod 9, which is fixedly connected to it, to move synchronously, thereby driving the control block 10 to move. The movement of the moving rod 9 will cause the sliding rod 11 to slide inside the slide groove. The sliding rod 11 will push the inclined block 7 to move. The movement of the inclined block 7 will cause the locking block 6 to slide on the side surface of the limit rod 5 and compress the spring 8 until the fixing block 3 is completely disengaged from the two locking blocks 6. At this time, the mounting baffle 2 can be removed for replacement or repair. When installation is required, place the mounting baffle 2 back in place. The device is placed on one side of the housing 1, with one side of the housing 1 protruding slightly from the mounting baffle 2 to support the mounting baffle 2 and prevent it from sliding downwards due to its own weight. Then, the two fixing blocks 3 are directly aligned with the two locking blocks 6 and pushed. The fixing blocks 3 first contact the inclined surfaces of the two locking blocks 6, thereby squeezing the two locking blocks 6 to both sides. The movement of the locking blocks 6 compresses the spring 8 until the locking blocks 6 enter the interior of the inclined block 7. At this point, the inclined block 7 is aligned. Then, the control block 10 is released, and the spring 8, due to its own elasticity, pushes the locking blocks 6 to lock the mounting baffle 2 and limit the locking blocks 6, thereby fixing the mounting baffle 2. The installation process is simple and quick, improving the practicality of the CNC machine tool protection device.

[0031] Furthermore, to facilitate the processing of the workpiece, such as Figure 1 , Figure 2 and Figure 4 As shown, a chuck 13 is fixedly connected to one inner wall of the device housing 1, and a slide rail 14 is fixedly connected to the bottom inner wall of the device housing 1.

[0032] Inside the outer casing 1 of the device, a movable frame 15 is slidably connected via a slide rail 14, and a processing tool 16 is fixedly connected to the top of the movable frame 15.

[0033] When using this CNC machine tool protective device, the operator can start the CNC machine tool and place the workpiece to be processed on the chuck 13. The chuck 13 can stably clamp the workpiece, ensuring that the workpiece will not shake or shift during processing. Subsequently, by controlling the moving frame 15 to slide on the slide rail 14, the position of the processing tool 16 relative to the workpiece can be adjusted. The smooth sliding of the moving frame 15 ensures that the processing tool 16 can move accurately along the predetermined trajectory, thereby achieving precise processing of the workpiece, which not only improves processing efficiency but also ensures processing quality.

[0034] It should be noted that, in order to facilitate penetration into the machine tool's interior and reduce the probability of the bulletproof glass 17 being scratched, such as... Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, a bulletproof glass 17 is fixedly connected to one side of the device housing 1, and a fixing frame 18 is fixedly connected to the inner wall of the device housing 1 near the bulletproof glass 17.

[0035] The fixed frame 18 has an internal mounting groove 19, and tempered glass 20 is slidably connected inside the mounting groove 19. Both the bulletproof glass 17 and the tempered glass 20 are set at an angle.

[0036] When in use, this CNC machine tool protective device allows operators to clearly observe the machining process inside the machine tool through the bulletproof glass 17, ensuring transparency and safety. Simultaneously, the tilted design of the bulletproof glass 17 and tempered glass 20 effectively reduces light refraction and reflection, preventing visual interference and further enhancing observation clarity. Furthermore, the design of the tempered glass 20 sliding within the mounting groove 19 allows for fine-tuning according to actual needs, ensuring a tighter fit with the bulletproof glass 17, reducing the entry of dust and debris, keeping the machine tool interior clean, and enabling quick replacement if the tempered glass 20 is scratched by debris. This enhances the practicality of the protective device and improves its durability and ease of maintenance.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
