[0002] A machine tool is a device that processes metal parts.
[0003] When the machine tool is processing parts, the automatic switch door is opened first. After the automatic switch door is opened, the parts are fixed in the machine tool, and then the automatic switch door is closed, and the cutter is started to process the parts. After the processing is completed, the automatic switch door is opened again to take out the processed parts.
[0004] When the machine tool is processing parts, the debris generated during the processing is blocked by the automatic opening and closing door, thereby playing a protective role. Since the automatic opening and closing door is frequently opened and closed, a protective mechanism is usually not provided at the closing part of the door body, which causes the door body to collide more frequently during the long-term closing process, resulting in damage to the door body, thereby reducing the service life of the automatic door body. In view of the above problems, the inventor proposes an automatic opening and closing door body for machine tools to solve the above problems. Utility Model Content

[0020] By adopting the above technical scheme, during the closing process of the door body 1, the door body 1 drives the fixed plate 2 to move, and the fixed plate 2 drives the supporting unit to move through the limiting unit. When the supporting units on both sides drive the buffer units to fit together, preliminary buffering is first performed by the buffer units, and then the door body 1 continues to approach. The buffer unit and the support unit are squeezed to compress the elastic unit with the assistance of the limiting unit and the rolling unit. At the same time, in the process of the elastic unit being squeezed and the supporting unit approaching the fixed plate 2, buffering protection is performed again by the shock-absorbing unit. When the support unit fits with the door body 1, the door body 1 is closed. By setting a protective mechanism, the closing part of the door body 1 is multi-protected by the protective mechanism during the operation of the automatic opening and closing door body of the machine tool, thereby reducing the impact on the two groups of door bodies 1 when closing, thereby improving the service life of the door body 1.
[0021] The supporting unit includes a first baffle 3 and a second baffle 4 , and the first baffle 3 is arranged on a side of the fixed plate 2 away from the door body 1 , and both ends of the first baffle 3 are fixedly connected to the second baffle 4 on a side close to the fixed plate 2 .

[0024] By adopting the above technical solution, when the two groups of support units are close to each other, they are buffered by the latex pad 5 and the first rubber pad 6.
[0025] The limiting unit includes a limiting block 7 and a second rubber pad 8, and the limiting block 7 is fixedly connected to the side opposite to the second baffle plate 4, the second rubber pad 8 is fixedly connected to both sides of the limiting block 7, and the end of the limiting block 7 away from the second baffle plate 4 is inserted and slidably arranged in the fixed plate 2.
[0026] By adopting the above technical solution, when the second baffle plate 4 moves, it drives the limiting block 7 and the second rubber pad 8 to slide in the fixed plate 2, and the movement of the second baffle plate 4 is limited by the limiting block 7 and the second rubber pad 8.
[0027] The rolling unit includes a roller 9 and a first limiting rod 10 , and the roller 9 is inserted inside the limiting block 7 , the two sides of the roller 9 are fixedly connected to the first limiting rod 10 , and the side of the first limiting rod 10 away from the roller 9 is transferred to the limiting block 7 .
[0028] By adopting the above technical solution, when the second rubber pad 8 moves, it drives the roller 9 and the first limiting rod 10 to move, so that the roller 9 rolls in contact with the fixed plate 2 under the limitation of the first limiting rod 10, and the rolling of the roller 9 assists the movement of the second baffle 4.
[0029] The elastic unit includes a second limiting rod 11 and a spring 12, and the second limiting rod 11 is fixedly connected to the side of the first baffle plate 3 close to the fixed plate 2, the end of the second limiting rod 11 away from the first baffle plate 3 is inserted in the fixed plate 2, and the spring 12 is sleeved on the outside of the second limiting rod 11, the end of the spring 12 away from the first baffle plate 3 is fixedly connected to the fixed plate 2, and the end of the spring 12 away from the fixed plate 2 is fixedly connected to the first baffle plate 3.
[0030] By adopting the above technical solution, when the first baffle plate 3 moves, it drives the second limit rod 11 to be inserted into the fixed plate 2. At the same time, the first baffle plate 3 compresses the spring 12, so that the elastic potential energy of the spring 12 can subsequently push the first baffle plate 3 and the second baffle plate 4 to reset.

[0032] By adopting the above technical solution, when the first baffle plate 3 is close to the fixed plate 2 , shock absorption is performed by the third rubber pad 13 and the sponge pad 14 .
[0033] Four groups of limiting units and rolling units are arranged at two ends of one side opposite to the second baffle 4, and the four groups of limiting units and rolling units are symmetrically arranged in pairs.
[0034] By adopting the above technical solution, four groups of limiting units and rolling units are symmetrically arranged in pairs at both ends of the second baffle 4, so as to make the movement of the second baffle 4 and the first baffle 3 more stable.
[0035] Working principle: when the two groups of door bodies 1 are controlled to close, the two groups of door bodies 1 drive the fixed plate 2 to move. After the fixed plate 2 moves, it drives the first baffle 3, the second baffle 4, the latex pad 5 and the first rubber pad 6 to move through the limit block 7, the second rubber pad 8, the second limit rod 11 and the spring 12. When the two groups of first rubber pads 6 are fitted, the door body 1 continues to approach, and then the first rubber pad 6, the latex pad 5, the second baffle 4 and the first baffle 3 are squeezed, and the second baffle 4 drives the limit block 7, the second rubber pad 8, the roller 9, the first limit rod 10, the second limit rod 11, the third rubber pad 13 and the sponge pad 14 to move. When the roller 9 moves, The first limit rod 10 is limited and rolls in contact with the fixed plate 2, and the rolling of the roller 9 assists the movement of the second baffle plate 4. At the same time, when the second limit rod 11 is inserted into the fixed plate 2, the first baffle plate 3 compresses the spring 12, the third rubber pad 13 and the sponge pad 14. The spring 12, the third rubber pad 13 and the sponge pad 14 buffer the contact between the first baffle plate 3 and the fixed plate 2. When the second baffle plate 4 is in contact with the door body 1, the closing of the door body 1 is completed. When the two groups of door bodies 1 are opened, the door body 1 moves in the opposite direction, and the elastic potential energy of the spring 12 is used to push the second limit rod 11, the second baffle plate 4 and the second baffle plate 4 back to their original positions.
