Technical Field

[0001] This utility model relates to a protective door, and more particularly to a protective door for CNC machine tools. Background Technology

[0002] The main function of CNC machine tool safety doors is to protect operators from potential injuries caused by moving parts of the machine tool, and also to prevent splashes of chips, coolant, etc. from affecting personnel.

[0003] For example, a protective door for a CNC machine tool, disclosed in Chinese Patent Publication No. CN222221981U, relates to the field of CNC machine tools. Its key technical features include: two N-shaped tracks installed on the upper and lower sides of the CNC machine tool surface; internal blocks slidably connected within each N-shaped track; one side of each N-shaped track being open for insertion of the internal blocks; a door body fixedly connected between the internal blocks; and an observation window on the door body. The protective door also includes an elastic structure installed on one side of the opening of the N-shaped track. This structure uses an elastically driven movable plate to block the opening of the N-shaped track. The effect is that the door body is easy to assemble and disassemble, and the structure of the door body is relatively simple, making it easier to manufacture, thereby improving the practicality of the protective door.

[0004] Some problems were found when using the existing protective door for CNC machine tools. First, the cutting fluid and other contaminants splashed on the protective door will contain some dirt, which will adhere to the cleaning mechanism. When cleaning the protective door later, the dirt will be evenly spread on the protective door. Utility Model Content

[0005] The purpose of this utility model is to provide a protective door for CNC machine tools to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective door for a CNC machine tool, comprising a slide rail and a protective door, with sliders symmetrically fixed to the back of the protective door, the sliders slidingly engaging with the slide rails, an observation window embedded in the front of the protective door, a cleaning mechanism fixed between the two slide rails, the cleaning mechanism comprising a connecting bracket and a support frame, a wiping cotton swab fixed to the front of the support frame, both ends of the support frame connected to the connecting bracket, the other end of the connecting bracket fixed to the slide rail, limit slots formed at both ends of the support frame, a limit buckle fixed to one end of the slide rail, the limit buckle engaging with the limit slot.

[0007] Preferably, a handle is fixedly attached to the front of the protective door.

[0008] Preferably, a limiting groove is provided on the front of the connecting bracket, a return spring is fixedly connected in the limiting groove, and a limiting pin is fixedly connected to the other end of the return spring.

[0009] Preferably, a displacement handle is fixedly connected to the limiting pin.

[0010] Preferably, the limiting slot has a fixing recess, which cooperates with the limiting pin.

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

[0012] 1. By fixing the cleaning mechanism between two slide rails, the protective door will come into contact with the cleaning cotton swab during its movement. The cleaning cotton swab will then scrape away the dirt behind the protective door, removing the dirt adhering to the back of the protective door. Compared with existing devices, this method has a simple structure and strong applicability.

[0013] 2. By using the displacement handle to move the limit pin, the limit pin can be moved out of the fixing recess, thus releasing the restriction on the support frame. The support frame can then be removed for cleaning to remove dirt from the surface of the wiping cotton swab, or the support frame can be replaced to avoid dirt on the wiping cotton swab affecting the subsequent cleaning effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a protective door for a CNC machine tool, including a slide rail 1 and a protective door 2. Slider 203 is symmetrically fixed to the back of the protective door 2, and the slider 203 slides with the slide rail 1. An observation window 201 is embedded in the front of the protective door 2. A cleaning mechanism is fixed between the two slide rails 1. The cleaning mechanism includes a connecting bracket 3 and a support frame 4. A cleaning cotton swab 401 is fixed to the front of the support frame 4. Both ends of the support frame 4 are connected to the connecting bracket 3. The other end of the connecting bracket 3 is fixed to the slide rail 1. Limiting slots 402 are opened at both ends of the support frame 4. A limiting buckle 301 is fixed to one end of the slide rail 1. The limiting buckle 301 and the limiting slot 402 cooperate with each other.

[0021] In this embodiment, by fixing the slide rail 1 to the CNC machine tool, the slider 203 slides and engages with the slide rail 1, thereby sliding the protective door 2 onto the CNC machine tool. The processing status inside the machine tool can be observed through the observation window 201. The cleaning mechanism is set between the two slide rails 1, and the connecting bracket 3 is fixed on the slide rail 1. During the sliding closing or opening of the protective door 2, the protective door 2 moves and comes into contact with the wiping cotton swab 401. The wiping cotton swab 401 rubs against the back of the protective door 2, scraping off the dirt adhering to the back of the protective door 2 and cleaning the surface behind the protective door 2. After a certain period of use, the wiping cotton swab 401 will be contaminated with some dirt. The limit buckle 301 and the limit slot 402 cooperate with each other, thereby locking the support frame 4 between the two connecting brackets 3. Later, the support frame 4 can be directly removed for cleaning, and the dirt on the surface of the wiping cotton swab 401 can be removed or replaced directly to avoid the wiping cotton swab 401 being contaminated and affecting the subsequent cleaning effect.

[0022] In order to achieve the purpose of fixing the support frame 4, the device adopts the following technical solution: a handle 202 is fixedly connected to the front of the protective door 2, a limiting groove 5 is opened on the front of the connecting bracket 3, a return spring 501 is fixedly connected in the limiting groove 5, a limiting pin 502 is fixedly connected to the other end of the return spring 501, a displacement handle 503 is fixedly connected to the limiting pin 502, and a fixing recess 403 is opened in the limiting slot 402, and the fixing recess 403 cooperates with the limiting pin 502.

[0023] The handle 202 can move the protective door 2. The return spring 501 can provide a certain pushing force to the limit pin 502. When the limit pin 502 is pushed, it will insert into the fixed recess 403, thereby fixing the limit buckle 301 in the limit slot 402, and then fixing the support frame 4 between the two connecting brackets 3. The displacement handle 503 can move the limit pin 502.

[0024] The working principle and usage process of this utility model are as follows: During use, the handle 202 can be used to move the protective door 2. During the movement of the protective door 2, it will come into contact with the cleaning cotton swab 401, thereby scraping away the dirt behind the protective door 2. During the opening and closing of the protective door 2, the dirt adhering to the back of the protective door 2 will be scraped off. After a period of use, the cleaning cotton swab 401 will be covered with a lot of dirt. It is necessary to use the displacement handle 503 to move the limit pin 502, and move the limit pin 502 out of the fixed recess 403. This can release the restriction on the support frame 4, and the support frame 4 can be directly removed for cleaning to remove the dirt on the surface of the cleaning cotton swab 401, or the support frame 4 can be directly replaced to avoid the cleaning cotton swab 401 being covered with dirt and affecting the subsequent cleaning effect.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
