The information carrier inputs the CNC device. In the processing flow of CNC machine tools, in order to improve work efficiency, it is often necessary to quickly replace workpieces. However, the feeding port of many CNC machine tools adopts a sliding door design. This door needs to be unlocked first and then pushed and pulled open to remove the workpiece for replacement. This process is relatively cumbersome and may affect production efficiency. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The protective device for CNC machine tools is provided with a fixed block, a slider, a slide groove, a baffle, a rope, a directional wheel, a fixed plate, a connecting block, a locking plate, a moving block, a handle and a limit groove. When the workpiece needs to be replaced quickly, it is only necessary to pull the handle, and the handle drives the moving block to slide in the locking plate, and then the moving block drives the rope to move. At this time, the rope drives the baffle to move through the directional wheel, and the baffle drives the two sliders to slide in the slide groove. Then, when the baffle is away from the loading port, the workpiece in the processing assembly can be taken out and replaced. When the replacement is completed, it is only necessary to release the handle, and the baffle is automatically reset by gravity to cover the loading port, thereby realizing the step of quickly replacing the workpiece, and the baffle can be quickly reset.

When it is necessary to clean the inside of the shell, it is only necessary to pull the handle to move the moving block to the limit rod. At this time, the moving block applies a thrust to the limit rod, and the thrust drives the limit rod to move. When the limit groove corresponds to the position of the limit rod, the pull-back spring applies an elastic force to the circular plate, and the elastic force drives the circular plate to move. The circular plate drives the limit rod to move, and then the limit rod is stuck in the limit groove. At this time, the inside of the shell and the processing components can be cleaned, avoiding the problem that the baffle will have an impact when cleaning the shell.

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a protective device for a CNC machine tool, comprising a shell 1, a processing assembly 2 is arranged in the shell 1, an observation window 3 is arranged on one side of the shell 1, a control panel 4 is connected to one side of the shell 1, a loading port 7 is opened on the front of the shell 1, a shielding device 5 is connected to the front of the shell 1, a locking device 6 is arranged in the shielding device 5, the locking device 6 comprises a limit plate 61, the limit plate 61 is connected to one side of the locking plate 509, a return spring 62 is connected in the limit plate 61, and a circular plate 63 is connected to one side of the return spring 62. By setting the return spring 62, when the limit rod 64 is not squeezed, the return spring 62 applies elastic force to the circular plate 63 to keep it stable. When the limit rod 64 loses its thrust, the return spring 62 applies elastic force to the circular plate 63, and the elastic force drives the circular plate 63 to move, so that it can be quickly reset.

[0021] One side of the circular plate 63 is connected to a limiting rod 64, which penetrates and is slidably connected in the locking plate 509, and the limiting rod 64 corresponds to the position of the limiting groove 512. The shielding device 5 includes two fixed blocks 501, and a sliding groove 502 is provided in the fixed block 501. A slider 503 is slidably connected in the sliding groove 502. By setting the sliding groove 502 and the slider 503, the sliding groove 502 cooperates with the slider 503, so that the sliding groove 502 limits the slider 503, thereby avoiding the problem of shaking of the slider 503 when sliding.

[0022] The two sliders 503 are connected with a same baffle 504, the baffle 504 is overlapped on the front of the loading port 7, the baffle 504 is overlapped in the two fixing blocks 501, and the locking plate 509 is connected to the front of the housing 1;

[0023] A rope 505 is connected to the baffle 504, and a directional wheel 506 is wound around the rope 505. A fixed plate 507 is connected to the back of the directional wheel 506, and the fixed plate 507 is connected to the shell 1. A connecting block 508 is connected to the front of the shell 1. One end of the rope 505 is connected to the moving block 510, and the connecting block 508 is slidably connected to the outside of the rope 505. A locking plate 509 is passed through the outside of the rope 505 and is slidably connected. The moving block 510 is slidably connected inside the locking plate 509, and a handle 511 is connected to the front of the moving block 510. A limiting groove 512 is provided in the moving block 510. By setting a limiting rod 64 and a limiting groove 512, the limiting rod 64 cooperates with the limiting groove 512, so that the limiting rod 64 limits the limiting groove 512 to prevent the limiting groove 512 from shaking or detaching.

[0024] The working principle of the utility model is:

[0025] When it is necessary to quickly replace the workpiece, it is only necessary to pull the handle 511, the handle 511 drives the moving block 510 to slide in the locking plate 509, and then the moving block 510 drives the rope 505 to move, at this time the rope 505 drives the baffle 504 to move through the directional wheel 506, the baffle 504 drives the two sliders 503 to slide in the slide groove 502, and then when the baffle 504 is away from the loading port 7, the workpiece in the processing assembly 2 can be taken out and replaced, and when the replacement is completed, it is only necessary to release the handle 511, at this time the baffle 504 is re-engaged. The force automatically resets. When it is necessary to clean the inside of the shell 1, it is only necessary to pull the handle 511 to move the moving block 510 to the limit rod 64. At this time, the moving block 510 applies a thrust to the limit rod 64, and the thrust drives the limit rod 64 to move. When the limit groove 512 corresponds to the position of the limit rod 64, the return spring 62 applies an elastic force to the circular plate 63, and the elastic force drives the circular plate 63 to move. The circular plate 63 drives the limit rod 64 to move, and then the limit rod 64 is stuck in the limit groove 512. At this point, the steps of quickly replacing the workpiece and cleaning the interior are completed.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connection", "sliding connection" and "hinge" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0027] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
