Description

Technical Field

[0001] The utility model relates to a sealing structure, in particular to a sealing mechanism for a machine tool protective door, belonging to the technical field of machine tool protective doors. Background Art

[0002] Machine tool protective doors are important safety devices installed on machine tools. They are usually made of metal materials such as iron or steel plates, and the surface is treated with rust prevention to adapt to the moisture and corrosion in the machine tool processing environment. Machine tool protective doors can be divided into single-leaf doors, double-leaf doors, sliding doors, telescopic doors, etc. according to their structure and purpose. Sliding doors rely on slide rails fixed to the door frame or the ground to guide the sliding of the protective doors, thereby realizing the opening and closing of the protective doors. In order to ensure the sealing of the protective doors, sealing strips are usually installed on the protective doors.

[0003] However, during the sliding process of the protective door, friction occurs between the rubber strip installed on the protective door and the door frame and the machine tool. Therefore, while the sealing strip increases the sealing performance, it also increases the friction between the protective door, the door frame and the machine tool to a certain extent, resulting in the protective door not sliding smoothly enough, which makes the protective door inflexible to use, and thus affects the safety of machine tool operation.

At the same time, the setting of the groove 203 enables the sealing strip 8 of the protective door body 3 to be pressed against the door frame 1 when the protective door body 3 is in the closed state, so that the sealing effect of the protective door body 3 is guaranteed.

[0025] As a technical optimization solution of the present invention, the bottom end of the protective door body 3 is rotatably connected to a plurality of rotating shafts 204, and a roller 205 is fixedly connected to the rotating shaft 204, and the roller 205 is rollingly connected to the slide rail 201; when the protective door body 3 slides on the slide rail 201, the protective door body 3 drives the plurality of rotating shafts 204 to rotate, and the rotating shafts 204 drive the rollers 205 to roll. The setting of the rollers 205 makes the sliding of the protective door body 3 smoother and more labor-saving, thereby improving the sliding flexibility of the protective door body 3.

[0026] As a technical optimization solution of the present utility model, tempered glass 4 is installed on the protective door body 3, and a handle 6 is installed on the protective door body 3. A rubber sleeve 7 is installed on the outside of the handle 6, and the handle 6 has an arc-shaped structure; the setting of the tempered glass 4 makes it convenient to observe the working conditions inside the machine tool through the tempered glass 4, and the setting of the handle 6 makes it convenient to pull the protective door body 3, and at the same time, the rubber sleeve 7 can increase the friction between the hand and the handle 6.

[0027] As a technical optimization solution of the present invention, the fixed structure 5 includes a connecting plate 501, the connecting plate 501 is fixedly connected to the door frame 1, and a blocking block 502 is slidably connected to the connecting plate 501. A blocking slot 503 is provided on the protective door body 3, and the blocking block 502 is engaged with the blocking slot 503. The end of the blocking block 502 facing away from the blocking slot 503 is fixedly connected to a pull plate 504, and the end of the blocking block 502 facing the blocking slot 503 is an inclined structure. A tension spring 505 is fixedly connected to the connecting plate 501, and the end of the tension spring 505 is fixedly connected to the pull plate 504; the protective door body 3 in the closed state is fixed by the fixed structure 5, so that the sealing strip 8 on the protective door body 3 is always pressed against the door frame 1, thereby making the sealing effect of the protective door body 3 better.

[0028] When the utility model is in use, first pull the handle 6 in the horizontal direction, the handle 6 drives the protective door body 3 to slide, and the protective door body 3 drives the rollers 202 at the upper and lower ends to slide in the slide grooves 206, and continuously pushes the protective door body 3. When the protective door body 3 slides to align with the door frame 1, the protective door body 3 is pushed toward the door frame 1, so that the protective door body 3 drives the rollers 202 to slide into the grooves 203. When the rollers 202 slide into the grooves 203, the rubber strips on the protective door body 3 come into contact with the door frame 1, thereby making the protective door body 3 A sealed environment is formed between the door body 3 and the door frame 1, and the protective door body 3 is used to isolate the dangerous area in the machine tool to protect the safety of the operator and prevent the cutting fluid, metal chips, etc. from polluting the machine tool and the surrounding environment. By providing a groove 203 perpendicular to the slide groove 206 on the slide rail 201, the protective door body 3 does not rub against the door frame 1 and the machine tool when sliding in the slide groove 206, thereby increasing the smoothness of the sliding of the protective door body 3. At the same time, the setting of the groove 203 enables the sealing strip 8 of the protective door body 3 to be closed when the protective door body 3 is closed. The locking block 502 of the protective door body 3 is pressed against the door frame 1 to ensure the sealing effect of the protective door body 3; in the process of pushing the protective door body 3 toward the door frame 1, the side wall of the protective door body 3 slides toward the end outside the connecting plate 501 against the blocking block 502. At this time, the blocking block 502 drives the pull plate 504 to move, and the pull plate 504 drives the tension spring 505 to extend, and continues to push the protective door body 3 until the card slot 503 on the protective door body 3 is aligned with the blocking block 502. After the blocking of the protective door body 3 is lost, the tension spring 505 is reset. By pulling the plate 504, the card block 502 is driven to engage in the card slot 503, so that the protective door body 3 can no longer slide, and the sealing strip 8 on the protective door body 3 is always pressed against the door frame 1, so that the sealing effect of the protective door body 3 is better; when the protective door body 3 slides on the slide rail 201, the protective door body 3 drives multiple rotating shafts 204 to rotate, and the rotating shafts 204 drive the rollers 205 to roll. The setting of the rollers 205 makes the sliding of the protective door body 3 smoother and more labor-saving, thereby improving the sliding flexibility of the protective door body 3.
