[0002] The high precision, high efficiency and high degree of automation of CNC machine tools have greatly improved the production quality and efficiency of products. The protective structure of CNC machine tools mainly includes machine tool casing, protective cover, protective door and other components. Closing the protective door during the processing process can prevent human operation of the machine tool from causing danger to people on the one hand, and on the other hand, it can prevent cutting fluid and cutting chips from splashing outside, polluting the ground and hurting the human body, playing a role in safety protection. Existing CNC machine tool protective doors are usually designed as single-door or double-door structures, generally fan-shaped and opened and closed in a hinged manner. When the staff leaves the equipment after cleaning or maintaining the inside of the equipment, and the staff inside the equipment are not clear about the external environment status when pushing open the protective door, the protective door opens and closes the rotation angle, which is easy to cause the protective door to collide with passing staff, thereby causing safety accidents.

DETAILED DESCRIPTION
[0018] The utility model is further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and not limiting of the protection scope of the utility model.
[0019] Example
[0020] like Figure 1-Figure 3As shown: a CNC machine tool protection structure, comprising: an outer shell 1, a door leaf 2 slidably connected inside the outer shell 1, a positioning block 3 is provided on one side of the door leaf 2, one end of the positioning block 3 magnetically cooperates with the door leaf 2, the door leaf 2 comprises a fixed plate 4, a handle 5 is provided on the outer side of the fixed plate 4, an upper sliding mechanism 6 is provided on the upper part of the fixed plate 4, a lower sliding mechanism 7 is provided on the lower part of the fixed plate 4, a square magnet 8 is provided on one side of the middle part of the fixed plate 4, and a transparent glass 10 for observation is provided in the middle of the fixed plate 4. The utility model has a door leaf inside the outer shell, and the door leaf is composed of a fixed plate, a handle, an upper sliding mechanism, a lower sliding mechanism and a limit block, which can effectively realize the movement of the door leaf inside the outer shell, avoid the rotation angle of the fan-shaped opening and closing, and the collision between the protective door and the passing staff, thereby causing a safety accident, and is easy to install.
[0021] It can be understood that: a group of limit blocks 9 are provided inside the handle 5, and a group of limit blocks 9 are hung and matched with the upper sliding mechanism 6 and the lower sliding mechanism 7. The existence of the limit blocks effectively limits the position of the door leaf during the sliding process, preventing it from deviating from the track due to unexpected factors, thereby ensuring the stability and safety of the door leaf and facilitating installation. By hanging and matching the upper sliding mechanism and the lower sliding mechanism, the limit blocks can further enhance the smoothness of the door leaf when sliding, reduce jamming and friction, and improve the operating experience.
[0022] It can be understood that: the upper sliding mechanism 6 includes a positioning bracket 601, sliding rods 602 are provided on both sides of the positioning bracket 601, springs 603 are provided on the outside of the sliding rods 602, the sliding rods 602 are slidably connected to the moving blocks 604, and multiple sets of pulleys 605 are provided on the inside of the moving blocks 604. The upper sliding mechanism can absorb and disperse external impact force during the sliding of the door leaf, thereby protecting the sliding mechanism from damage, automatically adjusting its elastic force, ensuring that the door leaf always remains stable during the sliding process, effectively reducing the friction resistance during the sliding process, and making the sliding of the door leaf smoother.
[0023] It can be understood that the lower sliding mechanism 7 is composed of a second positioning bracket 701, a spring 603, a pulley 605, a second moving block 702 and a second spring 703. The second positioning bracket 701 is provided with a spring upper limit block 704, and the second moving block 702 is provided with a spring lower limit block 705. The interior of the spring lower limit block 705 is tightly pressed with one end of the second spring 703, and the other end of the second spring 703 is tightly pressed with the interior of the spring upper limit block 704. The upper sliding mechanism can absorb and disperse external impact force during the sliding process of the door leaf, thereby protecting the sliding mechanism from damage, automatically adjusting its elastic force, ensuring that the door leaf always remains stable during the sliding process, effectively reducing the friction resistance during the sliding process, making the sliding of the door leaf smoother and at the same time supporting the main door leaf.
[0024] It can be understood that: one end of the second moving block 702 passes through the fixed plate 4 and is hung and matched with the limit block 9. One end of the limit block 9 is rotated to connect the inside of the handle 5. Only one end of the limit block needs to be gently pulled, and the limit block will rotate accordingly, and at the same time separate from the hanging part of the second moving block, thereby releasing the lock of the door leaf. This operation method is simple and convenient, greatly improves the use efficiency of the CNC machine tool, ensures the smooth cooperation between the limit block and the second moving block, and effectively avoids the jamming or damage caused by improper operation, and can realize the rapid installation and locking of the door leaf.
[0025] It can be understood that: one end of the moving block 604 passes through the fixed plate 4 and is hung and cooperated with the limit block 9. One end of the limit block 9 is rotated to connect the inside of the handle 5. Only one end of the limit block needs to be gently pulled, and the limit block will rotate accordingly, and at the same time, it will be separated from the hanging part of the moving block, thereby releasing the lock on the door leaf. This operation method is simple and convenient, which greatly improves the use efficiency of the CNC machine tool, ensures the smooth cooperation between the limit block and the moving block, and effectively avoids jamming or damage caused by improper operation, and can realize the rapid installation and locking of the door leaf.
[0026] The working process of the utility model is as follows: the protective structure of the CNC machine tool is mainly composed of an outer shell and a door leaf. The outer shell serves as an external protective layer, and the inner sliding part is connected to the door leaf. The door leaf is magnetically matched with the outer shell through a positioning block on one side to ensure the stability of the door leaf in a closed state. The door leaf contains a fixed plate inside, and a handle is provided on the outer side of the fixed plate to facilitate the operator to open and close the door leaf. An upper sliding mechanism is provided above the fixed plate inside, and a lower sliding mechanism is provided below. These sliding mechanisms provide support and guidance for the sliding of the door leaf. A square magnet is also embedded on one side of the middle of the fixed plate, which cooperates with the magnetism of the positioning block to enhance the stability of the door leaf. A transparent glass is also provided in the middle of the fixed plate to facilitate the operator to observe the internal situation of the machine tool. When the operator pulls the handle, the limit block rotates accordingly and releases the hanging and locking state with the upper and lower sliding mechanisms. At this time, the moving block and the second moving block can slide freely and drive the pulley to roll on the sliding rod. When the door leaf slides to the specified position, the limit block is again hung and locked with the upper and lower sliding mechanisms to ensure that the door leaf remains stable during the operation of the machine tool.
