A limit bracket A401 is rotatably set on the side of the inner wall of the groove B4 through a bearing, and the limit bracket A401 is set in an "L" shape, and the limit bracket A401 is movably set on the inner side of the slot 3. When the staff needs to use the CNC machine tool 1, the limit bracket A401 is pushed to rotate on the inner side of the slot 3 through the bearing, so that the direction of the limit bracket A401 is upward to release the protective cover 2, and the staff pushes the protective cover 2 to slide to the left on the inner side of the guide rail 102 through the sliding frame 201 to open The protective cover 2 drives the limit bracket A401 to slide out of the slot 3, and after the accessories to be processed are placed in the specified position of the CNC machine tool 1 and fixed, the protective cover 2 is pushed to the right through the sliding frame 201 to slide on the inner side of the guide rail 102, driving the limit bracket A401 to slide into the inner side of the slot 3, and then the limit bracket A401 is pushed to rotate through the bearing, so that the limit bracket A401 is limited downward on the inner side of the slot 3. When the staff uses the CNC machine tool 1 to process the accessories and generates vibration, the vibration can be avoided so that the protective cover 2 can be prevented from sliding open, resulting in debris and debris splashing out of the protective cover 2 to cause harm to the staff, thereby improving the effect of firmly locking the protective cover 2 to prevent loosening.

[0027] Reference Figure 1-Figure 6 , further, the limiting disassembly and assembly mechanism is composed of a groove A103, a limiting card plate 104 and a limiting card slot 202;

[0028] A groove A103 is embedded at the lower part of the inner wall of one of the guide rails 102, and a limit card plate 104 is rotatably arranged at the rear of the inner wall of the groove A103 through a rotating shaft and a torsion spring, and a limit card slot 202 is embedded at the lower part of the sliding frame 201 below the protective cover 2, and the inner wall of the limit card slot 202 is arranged in an arc shape, and the limit card plate 104 is slidably arranged at the inner side of the limit card slot 202. When the staff uses the CNC machine tool 1 for a long time, it is necessary to regularly disassemble and maintain the protective cover 2. The staff loosens and pushes the protective cover 2 to slide to the left on the inner side of the guide rail 102 through the sliding frame 201 to make the limit card slot 202 close to the groove A103. At this time, the tension state The torsion spring in the state drives the limit card plate 104 to rotate into the inner side of the limit card slot 202 through the rotating shaft to limit the protective cover 2. After opening the protective cover 2, the staff pushes the protective cover 2 a short distance to the right, squeezes the limit card plate 104 to rotate through the rotating shaft, and tightens the torsion spring. After the staff presses the limit card plate 104 on the inside of the groove A103, the protective cover 2 is pushed to the left to slide out of the guide rail 102 through the sliding frame 201, completing the disassembly of the protective cover 2. After the maintenance by the staff is completed, the upper and lower sliding frames 201 of the protective cover 2 are slid back to their original positions from the side of the inside of the guide rail 102, which is convenient for the staff to quickly disassemble and maintain the protective cover 2.

[0029] Reference Figure 4 , further, the resisting protection mechanism is composed of a protection grid 204;

[0030] A protective grid frame 204 is connected to the inside of the protective cover 2 by bolts, and the protective grid frame 204 is arranged in a grid mesh shape, and the surface material of the protective grid frame 204 is butadiene rubber. When the staff puts the accessories to be processed into the specified position of the CNC machine tool 1 and closes the protective cover 2, when the accessories are processed, debris will be continuously splashed to collide around the inner wall of the protective cover 2. At this time, the splashed debris will be blocked by the grid mesh protective grid frame 204, and the outer surface of the protective grid frame 204 made of butadiene rubber has the characteristics of high mechanical strength and wear resistance, which can reduce the force generated by the collision of the grid mesh protective grid frame 204, and protect the inner wall of the protective cover 2 to prevent the splashed debris from damaging the protective cover 2, reduce the maintenance times of the protective cover 2, and improve the effect that the protective cover 2 can be used for a long time without being easily damaged.

[0031] Reference Figure 1-Figure 6 Furthermore, the CNC machine tool 1 is electrically connected to an external power source through a matching control panel.

[0032] Embodiment 2:

[0033] like Figure 5 , Figure 7As shown, in addition to the embodiment in which a groove B4 is embedded in the front of the fixed baffle 101, a limit bracket A401 is rotatably arranged on the side of the inner wall of the groove B4 through a bearing, and the limit bracket A401 is arranged in an L" shape, and the limit bracket A401 is movably arranged on the inner side of the groove 3, there is another embodiment in which a groove C5 is embedded in the front of the fixed baffle 101, a limit bracket B501 is slidably arranged on the inner side of the groove C5, and the limit bracket B501 is arranged in a "J" shape, and the side of the limit bracket B501 is inclined, and the limit bracket B501 is slidingly arranged on the inner side of the groove 3, and a damping telescopic rod 502 is fixedly installed between the lower part of the limit bracket B501 and the lower part of the inner wall of the groove C5, and a spring is arranged on the outer side of the damping telescopic rod 502. When the staff needs to use the CNC machine tool 1, push it upward The dynamic limit bracket B501 drives the damping telescopic rod 502 and the outer spring to expand, so that the limit bracket B501 is loosened on the inner side of the slot 3. Then, the staff pushes the protective cover 2 to slide to the left on the inner side of the guide rail 102 through the sliding frame 201 to open the protective cover 2, driving the limit bracket B501 to slide out of the slot 3, and causing the damping telescopic rod 502 and the outer spring to contract the limit bracket B501. After the staff puts the accessories to be processed into the specified position of the CNC machine tool 1 and fixes them, they push the protective cover 2 to the right and slide on the inner side of the guide rail 102 through the sliding frame 201, squeezing the limit bracket B501 to drive the damping telescopic rod 502 and the outer spring to expand, so that the limit bracket B501 slides into the inner side of the slot 3. The damping telescopic rod 502 and the outer spring contract the limit bracket B501 and completely limit it more stably on the inner side of the slot 3. Compared with the first embodiment, the limiting effect is better.

[0034] Working principle: First, the staff needs to use the CNC machine tool 1 to push the limit bracket A401 to rotate inside the slot 3 through the bearing, so that the limit bracket A401 is upward and the protective cover 2 is loosened. The staff pushes the protective cover 2 to slide to the left on the inside of the guide rail 102 through the sliding frame 201 to open the protective cover 2, driving the limit bracket A401 to slide out of the slot 3, and put the parts to be processed into the specified position of the CNC machine tool 1 and fix them. Then, push the protective cover 2 to the right through the sliding frame 201 to slide on the inside of the guide rail 102, driving the limit bracket A401 to slide out of the slot 3. After the bracket A401 slides into the inner side of the slot 3, the limit bracket A401 is pushed to rotate through the bearing, so that the limit bracket A401 is limited downward to the inner side of the slot 3. When the staff uses the CNC machine tool 1 to process the accessories and generates vibration, it can avoid the vibration causing the protective cover 2 to slide open, resulting in debris and debris splashing out of the protective cover 2 to cause harm to the staff. Then, the accessories being processed will continuously splash out debris to collide with the inner wall of the protective cover 2. At this time, the splashed debris will be blocked by the grid mesh protective grid frame 204, and the butadiene rubber material The outer surface of the protective grid 204 has the characteristics of high mechanical strength and wear resistance, which can reduce the force generated by the collision of the grid mesh protective grid 204, and protect the inner wall of the protective cover 2 to prevent splashing debris from damaging the protective cover 2, thereby reducing the maintenance frequency of the protective cover 2. Finally, when the protective cover 2 needs to be disassembled and maintained regularly, the staff loosens and pushes the protective cover 2 to slide to the left on the inner side of the guide rail 102 through the sliding frame 201 so that the limit card slot 202 is close to the groove A103. At this time, the torsion spring in the tightened state drives the limit card plate 10 The protective cover 2 is limited by rotating the shaft into the inner side of the limit slot 202. After opening the protective cover 2, the staff pushes the protective cover 2 to the right for a short distance, squeezes the limit card plate 104 to rotate through the shaft, and tightens the torsion spring. After the staff presses the limit card plate 104 to the inner side of the groove A103, the protective cover 2 is pushed to the left to slide out of the guide rail 102 through the sliding frame 201, and the removal of the protective cover 2 is completed. After the maintenance by the staff is completed, the upper and lower sliding frames 201 of the protective cover 2 are slid back to their original positions from the inside of the guide rail 102.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
