Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention. It can be understood that the accompanying drawings are only for reference and illustration, and are not used to limit the present invention. The connection relationships shown in the drawings are only for clear description and do not limit the connection methods.

[0022] Please refer to in conjunction with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a detachable and cleanable protective door for a CNC machining center, including a CNC lathe 1, a protective door 2 is arranged on one side of the CNC lathe 1, a guide rod 3 is fixedly connected to the inner wall of the CNC lathe 1, an observation window 4 is arranged on one side of the protective door 2, a cleaning mechanism is arranged inside the protective door 2, and a connecting mechanism 5 is arranged outside the guide rod 3; the connecting mechanism 5 includes a connecting block 51 slidably connected to the outside of the guide rod 3, an arc-shaped clamping block 52 is slidably connected to the inner wall of the connecting block 51, a spring 53 is fixedly connected to one side of the arc-shaped clamping block 52, a threaded hole 54 is opened at the top of the connecting block 51, a slot 55 is opened on one side of the protective door 2, an arc-shaped card slot 56 is opened on the inner wall of the slot 55, and a fixing screw 57 is threadedly connected to the inner wall of the protective door 2.

[0023] A handle is fixedly connected to one side of the protective door 2, and the number of the connecting blocks 51 is set to four.

[0024] It should be noted that: when the cleaning mechanism is started, it can automatically clean and collect the debris and cutting fluid adsorbed on the observation window 4, avoiding the observation window 4 from being blocked. When the protective door 2 needs to be cleaned, first unscrew the fixing screw 57 on the protective door 2 to separate it from the threaded hole 54, and then pull the handle to move the protective door 2, so that the connecting block 51 is separated from the slot 55, and then the protective door 2 can be disassembled for comprehensive cleaning. Then move the protective door 2 to insert the connecting block 51 into the slot 55. At this time, the arc-shaped block 52 is retracted into the connecting block 51 under the extrusion of the slot 55, and the spring 53 is compressed. Continue to move the protective door 2. When the arc-shaped block 52 and the arc-shaped slot 56 are in a horizontal line, the spring 53 drives the arc-shaped block 52 to reset and snap into the arc-shaped slot 56. Finally, screw the fixing screw 57 into and penetrate the inner wall of the protective door 2 to connect with the threaded hole 54 at the top of the connecting block 51, thus completing the fixation of the protective door 2.

[0025] During the specific implementation process, as Figure 4 shown, the cleaning mechanism includes a motor 6 fixed on one side of the protective door 2. The output end of the motor 6 is fixedly connected with a lead screw 7. The inner wall of the lead screw 7 is threadedly connected with a scraper 8. The inner wall of the protective door 2 is fixedly connected with a positioning rod 9. The other side of the protective door 2 is fixedly connected with a collection box 10 through bolts.

[0026] The bottom of the lead screw 7 is rotationally connected with the inner wall of the protective door 2 through a bearing seat. The inner wall of the scraper 8 is slidably connected with the outer side of the positioning rod 9.

[0027] It should be noted that: start the motor 6 to drive the lead screw 7 to rotate. When the lead screw 7 rotates, it can drive the scraper 8 to move. Under the action of the positioning rod 9, it can prevent the scraper 8 from rotating with the lead screw 7, so that the scraper 8 remains stable during movement. Through the movement of the scraper 8, the debris and cutting fluid adsorbed on the observation window 4 can be cleaned off and fall into the collection box 10, which is convenient for personnel to process later.

[0028] Refer to Figure 1 shown, one side of the protective door 2 is fixedly connected with a magnetic block 11. After the protective door 2 is closed, it can be adsorbed on one side of the CNC lathe 1 through the magnetic block 11, so that the protective door 2 is limited. A buffer layer 12 is provided on the other side of the protective door 2. When the protective door 2 is closed, a buffering effect can be achieved through the buffer layer 12 to avoid the hard contact between the protective door 2 and the CNC lathe 1.

[0029] The buffer layer 12 is made of polyethylene material, which has a small density, good flexibility, high recovery rate, excellent impact resistance, and at the same time is resistant to the corrosion of organic solvents such as acids, alkalis, salts, and oils.

[0030] The working principle of a detachable and cleanable protective door for a CNC machining center provided by the present utility model is as follows:

[0031] During use, start the cleaning mechanism to clean and collect the debris and cutting fluid adsorbed on the observation window 4. When the protective door 2 needs to be cleaned, first unscrew the fixing screw 57 on the protective door 2, then pull the handle to move the protective door 2, so that the connecting block 51 is separated from the slot 55, and then the protective door 2 can be disassembled for comprehensive cleaning.

[0032] In the foregoing detailed description, reference has been made to the accompanying drawings, which form a part hereof. In the drawings, like numerals typically identify like components, unless the context indicates otherwise. The illustrated embodiments described in the detailed description, the drawings, and the claims are not meant to be limiting. Other embodiments may be used and other changes may be made without departing from the spirit or scope of the subject matter presented herein.

[0033] The foregoing is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
