[0002] During the machining process of graphite parts, the machine tool usually needs to be equipped with a skylight for loading and unloading. Secondly, since a large amount of dust is easily generated during the machining process of graphite materials, the skylight can effectively isolate and block the dust, which is beneficial to improving the working environment in the workshop and reducing the impact of dust on the health of workers.

[0003] The traditional skylight device usually sets a sliding baffle at the discharge channel on the top of the machine tool and opens and closes it manually by sliding. This method will cause the sliding baffle to exceed the outline of the machine tool when the skylight is opened, which not only affects the appearance of the machine tool, but also hinders the surrounding space and poses a safety hazard. Summary of the Utility Model

[0004] In order to overcome the problem that the traditional skylight device in the background art usually sets a sliding baffle at the discharge channel on the top of the machine tool and opens and closes it manually by sliding, which will cause the sliding baffle to exceed the outline of the machine tool when the skylight is opened, not only affecting the appearance of the machine tool, but also hindering the surrounding space and posing a safety hazard, the utility model provides a bellows type automatic opening and closing skylight for a machine tool for machining graphite parts; a traction mechanism and a foldable bellows type baffle are arranged at the skylight opening of the machine tool, and the bellows type baffle is driven to reciprocate by the traction mechanism, realizing the automatic opening and closing function of the bellows type baffle. The degree of automation is high, which not only optimizes the spatial layout of the machine tool, avoids the problem of safety hazards caused by the traditional sliding baffle exceeding the outline of the machine tool during the opening process, but also effectively prevents the dust inside the machine tool from diffusing to the outside of the machine tool during the machining process, can improve the working environment in the workshop, and reduce the impact of dust on the health of workers.

[0005] To achieve the above object, the utility model is realized by the following technical solutions: a bellows type automatic opening and closing skylight for a machine tool for machining graphite parts mainly includes a window frame, a bellows type baffle, and a traction mechanism. The window frame is installed at the skylight channel opening at the top of the machine tool. There is a foldable bellows type baffle inside the window frame, and a traction mechanism for driving the automatic opening and closing of the bellows type baffle is installed on the side of the window frame.

[0016] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the drawings for the convenience of those skilled in the art to understand.

[0017] The utility model discloses a bellows type automatic opening and closing skylight for a graphite part processing machine tool. The bellows type automatic opening and closing skylight for a graphite part processing machine tool mainly comprises a window frame 1, a bellows type baffle 2, and a traction mechanism 3. The window frame 1 is installed at the skylight passage opening at the top of the machine tool. There is a foldable bellows type baffle 2 inside the window frame 1. A traction mechanism 3 for driving the automatic opening and closing of the bellows type baffle 2 is installed on the side of the window frame 1. The traction mechanism 3 includes a guide rail 301, a slider 302, a reduction motor 303, a rack 304, a gear 305, a traction rod 306, and a connecting block 307. The guide rail 301 is installed at the top of the machine tool. The reduction motor 303 is slidably installed on the guide rail 301 through the slider 302 and is electrically connected to the machine tool control system. A through hole is formed in the slider 302. The output shaft of the reduction motor 303 passes through the through hole of the slider 302 and a gear 305 is installed at its end. A rack 304 meshing with the gear 305 is longitudinally installed on the guide rail 301. A traction rod 306 for driving the movement of the bellows type baffle 2 is installed on the side of the slider 302. Connecting blocks 307 connected to the edge of the bellows type baffle 2 are equidistantly arranged on the traction rod 306.

[0018] The utility model is installed at the skylight opening of a fully automated graphite part processing machine tool. When the machine tool is ready to start processing graphite parts, the control system of the machine tool receives a signal and starts the reduction motor 303 to work. The reduction motor 303 transmits torque to the gear 305 and the rack 304, further driving the slider 302 to move along the guide rail 301. The bellows-type baffle 2 is driven to fold through the towing rod 306 on the guide rail 301. Then, the graphite parts are placed inside the machine tool through automated equipment. The transmission structure of the gear 305 and the rack 304 has the advantages of high efficiency, rapidity and stability in transmission. The control system of the machine tool receives a signal again and starts the reduction motor 303 to work. The reduction motor 303 drives the gear 305 to rotate in the reverse direction, thereby driving the slider 302 and the towing rod 306 to move in the reverse direction. The bellows-type baffle 2 is driven to unfold through the towing rod 306. At this time, the machine tool starts to process the graphite parts. The unfolded bellows-type baffle 2 can effectively block dust and prevent it from spreading to the external environment of the machine tool, which can effectively improve the working environment of the workshop and reduce the impact of dust on the health of workers. When the processing of the graphite parts is completed, the control system of the machine tool receives a signal, and the bellows-type baffle 2 is driven to fold through the towing mechanism 3. The graphite parts are taken out through automated equipment. The machine tool can continue the next round of processing operations. During the whole working process, the automatic opening and closing of the bellows-type baffle 2 provides great convenience for the operation of the machine tool and improves the production efficiency. By setting a towing mechanism and a foldable bellows-type baffle at the skylight opening of the machine tool, and driving the bellows-type baffle to reciprocate through the towing mechanism, the automatic opening and closing function of the bellows-type baffle is realized. The degree of automation is high. It not only optimizes the spatial layout of the machine tool, avoids the problem of potential safety hazards caused by the traditional sliding baffle exceeding the outer shape of the machine tool during the opening process, but also effectively prevents the dust inside the machine tool from spreading to the outside of the machine tool during the processing process and reduces the impact of dust on the health of workers.

[0019] A limiting groove 101 for limiting the two side edges of the bellows-type baffle 2 is formed inside the window frame 1. One end of the bellows-type baffle 2 is fixed inside the window frame 1, and the two side edges are slidably fitted inside the limiting groove 101. The limiting groove 101 can not only limit the side edges of the bellows-type baffle 2, but also is beneficial to blocking the leakage of dust inside the machine tool and effectively reducing the impact of dust leakage on the health of workers.

[0020] A stop block 309 is installed at the end of the guide rail 301. Photoelectric switches 308 are installed at both the front and rear ends of the slider 302. The photoelectric switches 308 are electrically connected to the control system of the machine tool. When the end of the slider 302 approaches the stop block 309, the control system of the machine tool receives the signal fed back by the photoelectric switches 308 and controls the reduction motor 303 to stop working.

[0021] Working process:

[0022] When the machine tool is ready to start machining graphite parts, the control system of the machine tool receives a signal and starts the reduction motor 303 to work. The reduction motor 303 transmits torque to the gear 305 and the rack 304, further driving the slider 302 to move along the guide rail 301. The bellows cover 2 is driven to fold through the towing rod 306 on the guide rail 301. When the end of the slider 302 approaches the stop block 309, the control system of the machine tool receives the signal fed back by the photoelectric switch 308 and controls the reduction motor 303 to stop working. Then, the graphite parts are placed inside the machine tool through automated equipment; the transmission structure of the gear 305 and the rack 304 has the advantages of high efficiency, rapidity, and stability in transmission. The control system of the machine tool receives a signal again and starts the reduction motor 303 to work. The reduction motor 303 drives the gear 305 to rotate in the reverse direction, thereby driving the slider 302 and the towing rod 306 to move in the reverse direction. The bellows cover 2 is driven to unfold through the towing rod 306. When the end of the slider 302 approaches the stop block 309, the control system of the machine tool receives the signal fed back by the photoelectric switch 308 and controls the reduction motor 303 to stop working. At this time, the machine tool starts to machine the graphite parts. The unfolded bellows cover 2 can effectively block dust and prevent it from spreading to the external environment of the machine tool, which can effectively improve the working environment of the workshop and reduce the impact of dust on the health of workers. When the machining of the graphite parts is completed, the control system of the machine tool receives a signal, and the bellows cover 2 is driven to fold through the traction mechanism 3. The graphite parts are taken out through automated equipment. The machine tool can continue the next round of machining operations. During the entire working process, the automatic opening and closing of the bellows cover 2 provides great convenience for the operation of the machine tool and improves production efficiency. By setting a traction mechanism and a foldable bellows cover at the skylight opening of the machine tool, and driving the bellows cover to reciprocate through the traction mechanism, the automatic opening and closing function of the bellows cover is realized. The degree of automation is high, which not only optimizes the spatial layout of the machine tool, avoids the problem of potential safety hazards caused by the traditional sliding baffle exceeding the outer shape of the machine tool during the opening process, but also effectively prevents the dust inside the machine tool from spreading to the outside during the machining process and reduces the impact of dust on the health of workers.
