[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 The top of the machine tool 1 is fixedly provided with an upper slide rail 2, and the bottom of the machine tool 1 is fixedly provided with a lower slide rail 3. The upper slide rail 2 and the lower slide rail 3 have different structures. A protective plate 4 is installed between the lower slide rail 3 and the upper slide rail 2. The protective plate 4 not only serves as a door, but also realizes the function of protection. A wall panel 5 is fixedly installed on the inner wall of the machine tool 1, and baffles 6 are fixedly installed at both ends of the lower slide rail 3 and the upper slide rail 2. A return mechanism is provided on the front of the wall panel 5. The return mechanism includes a guide rod 10, a slider 11 and a return spring 12. Two mounting grooves are provided on the front of the wall panel 5. Both ends of the guide rod 10 are fixedly connected to the inner wall of the mounting groove. The slider 11 is slidably sleeved on the outer side of the guide rod 10, and the return spring 12 is sleeved on the outer side of the guide rod 10. In this design, the return spring 12 is in a compressed state at any position. The front of the slider 11 is fixedly connected to the back of the protective plate 4, and the bottom end of the upper slide rail 2 is provided with a damping mechanism.

[0024] The damping mechanism includes a damping tube 9 and a damping rod 7. The two ends of the damping rod 7 are fixedly connected to one side of the two baffles 6 respectively. The damping tube 9 is slidably sleeved on the outer side of the damping rod 7. The use of the damping tube 9 and the damping rod 7 is used to reduce the rapid movement of the protective plate 4 when the elastic potential energy of the return spring 12 is released, so as to prevent the protective plate 4 from moving rapidly and pinching the hand or directly and quickly colliding with the baffle 6.

[0025] Four clamping blocks 8 are fixedly connected to the top of the protective plate 4 . The clamping blocks 8 are all interlaced and connected with the damping rod 7 . The clamping blocks 8 are used to limit the lateral movement of the damping tube 9 .

[0026] A partition bar 13 is fixedly installed on the front of the wall panel 5. One side of the partition bar 13 is flush with one end of the wall panel 5. The front of the partition bar 13 is in contact with the back of the protective plate 4. It has a certain degree of flexibility and is used to prevent metal chips from flying out during processing of the machine tool 1.

[0027] The inner wall of the bottom of the protective plate 4 is evenly fixedly connected with multiple pins 14, and the outer side of the pin 14 is rotatably sleeved with a roller 15. The outer side of the roller 15 is rollingly connected to the top of the lower slide rail 3. The roller 15 is designed to reduce the wear of the bottom end of the protective plate 4 when it moves.

[0028] A special-shaped hole is provided in the middle of one of the baffles 6, and a pull buckle 16 is installed inside the special-shaped hole. A plug-in plate 17 is fixedly installed on one side of the protective plate 4. The position of the plug-in plate 17 corresponds to the position of the special-shaped hole. The pull buckle 16 and the plug-in plate 17 can fix the protective plate 4 together. A handle is fixedly installed on the front of the protective plate 4.

[0029] According to the working principle and process of the present invention, when the operator needs to open the protective plate 4 to operate the machine tool 1, the operator pulls the handle to one end, so that the protective plate 4 moves along the lower rail 3, and the protective plate 4 drives the block 8 and the slider 11 to move, and the block 8 pushes the damping tube 9 to move along the surface of the damping rod 7.

[0030] At the same time, the slider 11 moves along the surface of the guide rod 10 and compresses the return spring 12 until the insert plate 17 is inserted into the special-shaped hole and lifts the pull buckle 16. The insert plate 17 continues to move, and the pull buckle 16 falls to the upper plane of the insert plate 17, so that the insert plate 17 is fixed. The operator releases the handle, and the protective plate 4 is fixed at this time.

[0031] After the operator has completed the operation in the inner cavity of the machine tool 1, the operator pushes the protective plate 4 with one hand and pulls the buckle 16 upward with the other hand. The operator slowly releases the handle, and the protective plate 4 moves away from one of the baffles 6 equipped with the buckle 16 under the elastic action of the return spring 12 until one side of the protective plate 4 contacts the other baffle 6.
