Description

Technical Field

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

[0002] Protective devices act as a "safety shield" for operators. During CNC machine tool operation, the high-speed rotation of the cutting tool and the violent collision of the workpiece create numerous hazards. Protective devices effectively block flying chips, coolant, and potential workpiece fragments, preventing these hazards from causing bodily injury to operators and significantly reducing the probability of workplace accidents, allowing operators to work in a relatively safe environment. Simultaneously, they also serve as a "protective barrier" for the equipment. External dust and impurities can easily enter the machine tool, affecting its accuracy and lifespan. Protective devices can block these adverse external factors, keeping the machine tool's interior clean, reducing equipment malfunctions and wear caused by contamination, ensuring the machine tool remains in a stable operating state, and maintaining its machining accuracy and performance.

[0003] Currently, there is a significant pain point in the use of protective devices for CNC machine tool processing—the disassembly and assembly of protective covers is extremely inconvenient. Every time operators need to inspect, maintain, or clean chips from the inside of the machine tool, they often have to spend a lot of time repeatedly tightening screws and adjusting clips because the protective cover has a complex fixed structure and lacks a quick opening and closing design. This is not only cumbersome and laborious, but also slows down the equipment maintenance rhythm and greatly affects daily processing efficiency and flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for CNC machine tool processing, which solves the problem that it is inconvenient to disassemble and install the protective cover during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for CNC machine tool processing, comprising a base, a support base fixedly connected to the upper end of the base, a CNC machine tool body disposed at the upper end of the support base, a mounting seat contacting the front of the CNC machine tool body, a protective cover fixedly connected to the side of the mounting seat away from the CNC machine tool body, a fixed door and a connecting door respectively disposed inside the protective cover, a sliding groove provided inside the mounting seat, a slider slidably connected inside the sliding groove, a connecting block fixedly connected to the side of the slider away from the mounting seat, a connecting groove provided inside the CNC machine tool body, a positioning block fixedly connected to the side of the connecting blocks away from each other, the positioning block slidably connected to the CNC machine tool body, a threaded rod rotatably connected inside the mounting seat, and a limit mechanism disposed on the fixed door.

[0006] Preferably, a pad is fixedly connected to the lower end of the protective cover, and the pad contacts the support base. The design of the pad ensures that the protective cover remains stable after installation.

[0007] Preferably, the fixed door and the connecting door are in contact, and the fixed door and the connecting door are connected to the protective cover by hinges respectively. Both the fixed door and the connecting door are equipped with observation windows. The hinged connection allows the fixed door and the connecting door to be opened and closed flexibly, facilitating quick operation, observation, or maintenance by the operator when needed. The observation window design allows the operator to observe the processing status inside the machine tool in real time without opening the door, ensuring operator safety, providing timely information on processing progress and status, improving work efficiency, and reducing the safety risks and energy consumption caused by frequent door openings.

[0008] Preferably, the connecting block contacts the mounting base, and the connecting block is slidably connected to the connecting groove. The contact between the connecting block and the mounting base, as well as the slidable connection with the connecting groove, ensures that the connecting block can smoothly follow the movement of the slider when the slider moves in the groove, and provides precise guidance for the movement of the connecting block.

[0009] Preferably, the threaded rod has positive and negative threads on its outer side, and the threaded rod is connected to the slider via threads. The threaded rod can synchronously drive the connecting block and the positioning block to move. This allows for more efficient and balanced operation of the positioning block in limiting and releasing the protective cover, reducing operation steps and time, improving the efficiency of the protective cover's assembly and disassembly, and ensuring the consistency of the positioning block's movement on both sides, thus enhancing the stability of the protective cover's installation.

[0010] Preferably, a retaining ring is fixedly connected to the outer side of the threaded rod, and the retaining ring contacts the inner wall of the mounting base. A knob is fixedly connected to the upper end of the threaded rod, and the knob contacts the mounting base. The retaining ring contacts the inner wall of the mounting base, which serves to provide axial positioning, preventing axial movement of the threaded rod during rotation and ensuring that the rotational motion of the threaded rod is accurately converted into the linear motion of the slider. This improves the stability and reliability of the entire limiting and unlocking mechanism. The knob design provides the operator with a convenient point of force application. The operator can easily control the rotation of the threaded rod by rotating the knob without the need for additional tools, thus improving the convenience of operation.

[0011] Preferably, the limiting mechanism includes a limiting plate, a pull ring fixedly connected to the upper end of the limiting plate, a limiting block fixedly connected to the lower end of the limiting plate, the limiting plate contacting the connecting door, the limiting block slidably connected to the connecting door, a sliding rod fixedly connected to the lower end of the limiting plate, a sliding plate fixedly connected to the lower end of the sliding rod, the sliding plate slidably connected to the fixed door, a limiting ring fixedly connected inside the fixed door, the limiting ring contacting the limiting plate, the limiting ring slidably connected to the sliding rod, and a spring provided on the outer side of the sliding rod, one end of the spring contacting the sliding plate, and the other end of the spring contacting the limiting ring. The pull ring allows the operator to manually pull the limiting plate, thereby controlling the movement of the limiting block. The sliding connection between the limiting block and the connecting door, and the contact between the limiting plate and the connecting door, effectively limit the movement of the fixed door and the connecting door, preventing accidental opening and ensuring the safety of the operator.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features an innovative design with a linkage structure between the slider, connecting block, positioning block, and threaded rod: Rotating the threaded rod drives its threaded engagement with the slider, which in turn moves the slider via the connecting block, displacing the positioning block from its mounting seat position. This allows for quick release of the protective cover's limiting mechanism and convenient disassembly. The reverse operation completes the installation and fixing process. This structure uses threaded transmission to precisely control the movement of the positioning block, effectively solving the problem of cumbersome disassembly and assembly of traditional protective covers and significantly improving operational efficiency.

[0013] 2. This utility model innovatively adopts a limiting structure that combines a limiting plate, a limiting block, and a spring: when the connecting door and the fixed door are closed, the spring releases its elastic force to drive the limiting block on the limiting plate to precisely slide into the corresponding slot of the connecting door, forming a stable limiting fit. This design utilizes the conversion of elastic potential energy to achieve automatic locking, ensuring a tight closure between the fixed plate and the connecting door without the need for additional tools, effectively enhancing the stability of the protective door connection and simplifying the closing operation process.

The design of the observation window 25 allows operators to observe the processing inside the machine tool in real time without opening the door. This ensures the safety of the operators, allows them to understand the processing progress and status in a timely manner, improves work efficiency, and also reduces the safety risks and energy consumption caused by frequent door opening.

[0018] Please see Figure 2-5The mounting base 2 has a sliding groove 3 inside, and a slider 31 is slidably connected inside the sliding groove 3. A connecting block 32 is fixedly connected to the side of the slider 31 away from the mounting base 2. The CNC machine tool body 12 has a connecting groove 33 inside. The connecting block 32 contacts the mounting base 2 and is slidably connected to the connecting groove 33. The contact between the connecting block 32 and the mounting base 2 and the sliding connection with the connecting groove 33 ensure that the connecting block 32 can move smoothly with the slider 31 when the slider 31 moves in the sliding groove 3, and provides precise guidance for the movement of the connecting block 32. A positioning block 34 is fixedly connected to the side of the connecting block 32 away from each other. The positioning block 34 is slidably connected to the CNC machine tool body 12. A threaded rod 35 is rotatably connected inside the mounting base 2. The outer side of the threaded rod 35 is provided with positive and negative threads. The threaded rod 35 is threadedly connected to the slider 31. The threaded rod 35 can synchronously drive the connecting block 32 and the positioning block 34 to move. This allows for more efficient and balanced operation of the positioning block 34 in limiting and releasing the protective cover 21, reducing operation steps and time, improving the efficiency of disassembling and assembling the protective cover 21, ensuring the consistency of the movement of the positioning blocks 34 on both sides, and enhancing the stability of the installation of the protective cover 21.

[0019] Please see Figure 2-5 A retaining ring 36 is fixedly connected to the outer side of the threaded rod 35, and the retaining ring 36 contacts the inner wall of the mounting base 2. A knob 37 is fixedly connected to the upper end of the threaded rod 35, and the knob 37 contacts the mounting base 2. The retaining ring 36 contacts the inner wall of the mounting base 2, which serves to axially position the threaded rod 35 and prevent it from axially shifting during rotation. This ensures that the rotational motion of the threaded rod 35 can be accurately converted into the linear motion of the slider 31, improving the stability and reliability of the entire limiting and unlocking mechanism. The knob 37 provides a convenient force application point for the operator. The operator can easily control the rotation of the threaded rod 35 by rotating the knob 37 without the need for additional tools, improving the convenience of operation. A limit mechanism 4 is provided on the fixed door 23.

[0020] Please see Figure 2-5The limiting mechanism 4 includes a limiting plate 41, with a pull ring 42 fixedly connected to the upper end of the limiting plate 41 and a limiting block 43 fixedly connected to the lower end of the limiting plate 41. The limiting plate 41 contacts the connecting door 24, and the limiting block 43 is slidably connected to the connecting door 24. A slide rod 45 is fixedly connected to the lower end of the limiting plate 41, and a slide plate 46 is fixedly connected to the lower end of the slide rod 45. The slide plate 46 is slidably connected to the fixed door 23. A limiting ring 47 is fixedly connected inside the fixed door 23. The limiting ring 47 contacts the limiting plate 41 and is slidably connected to the slide rod 45. A spring 48 is provided on the outside of the slide rod 45. One end of the spring 48 contacts the slide plate 46, and the other end of the spring 48 contacts the limiting ring 47. The pull ring 42 allows the operator to manually pull the limiting plate 41 to control the movement of the limiting block 43. The sliding connection between the limiting block 43 and the connecting door 24, as well as the contact between the limiting plate 41 and the connecting door 24, can effectively limit the fixed door 23 and the connecting door 24, preventing them from opening accidentally and ensuring the safety of the operators.

[0021] The specific implementation process of this utility model is as follows: In use, by moving the limiting plate 41 away from the fixed door 23, the limiting plate 41 drives the sliding rod 45 to move, and the sliding rod 45 drives the sliding plate 46 to squeeze the spring 48. Then, the fixed door 23 and the connecting door 24 are closed. Then, the limiting plate 41 is released, and the spring force of the spring 48 drives the sliding plate 46 to move. The sliding plate 46 drives the limiting plate 41 to move through the sliding rod 45, and the limiting plate 41 drives the limiting block 43 to slide into the connecting door 24, which can limit the connecting door 24 and keep the fixed door 23 and the connecting door 24 stable after they are closed. By rotating the knob 37, the threaded rod 35 is rotated, causing the threaded rod 35 and the slider 31 to move in a threaded motion. This causes the slider 31 to move on the threaded rod 35, which in turn causes the connecting block 32 to move. The connecting block 32 then causes the positioning block 34 to move, allowing the positioning block 34 to slide out of the CNC machine tool body 12. This releases the limit on the mounting base 2, allowing the protective cover 21 to be removed from the CNC machine tool body 12.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
