[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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 an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Example 1 Reference Figures 1-3 This utility model discloses a CNC machine tool protective door with an internal cleaning structure, including a door body 1 and a viewing window 2 disposed on the door body 1. It also includes a lateral sliding structure, a rack 3, and a cleaning structure fixed to the inner wall of the door body 1. The lateral sliding structure includes a slide that moves along the length of the viewing window 2. The rack 3 is horizontally disposed along the length of the viewing window 2. The cleaning structure includes a cleaning shaft 4 rotatably disposed on the slide. Multiple rubber brushes 13 are evenly disposed on the outer wall of the cleaning shaft 4. A gear 5 is fixed to one end of the cleaning shaft 4, and the gear 5 meshes with the rack 3.
[0024] With the above structure, when the door 1 cannot be opened while the machine tool is working, and when the viewing window 2 is contaminated by wastewater generated during processing, the operator can control the slide located inside the door 1 to move when the viewing window 2 needs to be cleaned. This will drive the cleaning shaft 4 to move along the length of the viewing window 2. During the movement, the gear 5 drives the cleaning shaft 4 to rotate under the restriction of the rack 3, so as to clean the viewing window 2 through the rubber brush 13 on the surface and scrape off the dirt on the viewing window 2, thus ensuring the cleanliness of the viewing window 2.
[0025] In detail, in this embodiment, the transverse structure includes a first housing 6 and a second housing 7 fixed to both sides of the viewing window 2. A lead screw 8 is rotatably connected inside the first housing 6, and a guide rod 9 is connected inside the second housing 7. The slide includes a nut block 10 and a slider 11. The nut block 10 is sleeved on the outside of the lead screw 8, and the slider 11 is sleeved on the outside of the guide rod 9. A bearing seat 12 is fixed on one side of both the nut block 10 and the slider 11. The end of the cleaning shaft 4 is rotatably disposed inside the bearing seat 12.
[0026] In detail, in this embodiment, the rack 3 is located inside the first housing 6. The arrangement of the first housing 6 and the second housing 7 can protect the lead screw 8 and rack 3 located in the first housing 6, and protect the guide rod 9 located in the second housing 7, minimizing contamination from pollutants generated during machine tool processing. If water enters the second housing 7, it will drain out through the perforation at the bottom of the second housing 7. A drive motor 14 is fixed on the door body 1, and the output end of the drive motor 14 is fixedly connected to one end of the lead screw 8. The drive motor 14 can drive the lead screw 8 to rotate, thereby moving the cleaning shaft 4 along the viewing window 2; of course, other drive structures that control the rotation of the lead screw 8 can also be used.
[0027] In detail, in this embodiment, limit switches 15 are fixed at both ends of the second housing 7 on the door body 1, and trigger plates 16 corresponding to the limit switches 15 are fixed on the slider 11. The limit switches 15 are electrically connected to the drive motor 14. When the trigger plate 16 on the slider 11 moves to the limit switch 15 at one end, the drive motor 14 will reverse. The setting of limit switches 15 at both ends enables the drive motor 14 to drive the cleaning shaft 4 to perform reciprocating cleaning motion along the viewing window 2 through the lead screw 8, thereby improving the cleaning effect on the viewing window 2. In addition, a handle 21 is fixedly provided on the outer wall of the door body 1 for easy pulling of the door body 1.
[0028] Example 2 Reference Figures 1-3 Based on the same concept as in Embodiment 1, the CNC machine tool protective door with an internal cleaning structure also includes a pipe frame 17 fixed on one side of both the nut block 10 and the slider 11. A spray pipe 18 is fixed at the end of the pipe frame 17 away from the viewing window 2. Multiple spray heads 19 are evenly arranged on the surface of the spray pipe 18, with the spray heads 19 facing the viewing window 2 and not obstructed by the rubber brush 13. The top of the spray pipe 18 is connected to an external water pump via a hose 20. The spray pipe 18 moves with the movement of the nut block 10 and the slider 11. That is, while scraping away dirt from the viewing window 2, if rinsing with clean water is required, the external water pump can be activated, and external clean water can be sprayed onto the viewing window 2 through the spray heads 19 of the spray pipe 18, effectively cleaning the viewing window 2 in conjunction with the rubber brush 13.
[0029] Working principle: When the machine tool is working, the viewing window 2 is contaminated by wastewater generated during processing. Before using the viewing window 2, the operator can start the drive motor 14. The drive motor 14 drives the lead screw 8 to rotate, which in turn drives the cleaning shaft 4 to move along the viewing window 2. The gear 5, limited by the rack 3, drives the cleaning shaft 4 to rotate, so that the rubber brush 13 on the surface can clean the viewing window 2 and scrape off the dirt. The limit switches 15 at both ends enable the drive motor 14 to drive the cleaning shaft 4 to reciprocate along the viewing window 2 through the lead screw 8, improving the cleaning effect of the viewing window 2. The spray pipe 18 moves with the nut block 10 and the slider 11. That is, while scraping off the dirt from the viewing window 2, if it is necessary to rinse with clean water, the external water pump can be started. External clean water can be sprayed onto the viewing window 2 through the spray head 19 of the spray pipe 18, which, together with the rubber brush 13, achieves effective cleaning of the viewing window 2.
[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
