As shown in fig. 10, as an embodiment of the present invention, the air suction device 16 includes a second motor 41 and a suction fan 42, the second motor 41 is installed on the top of the machine tool housing 1, the suction fan 42 is provided with a plurality of suction fans 42 inside the upper air duct 15, a rotating shaft of the suction fan 42 is installed on the upper air duct 15 through a bearing plate, a turbine 43 is fixedly connected to the rotating shaft of the suction fan 42, the turbine 43 is engaged with a worm 44, a second chain wheel 45 is fixedly connected to both one end of the worm 44 located outside the upper air duct 15 and an output shaft of the second motor 41, and a second chain 46 is engaged outside the second chain wheel 45. When the air blower is used, the second motor 41 is started, the worm 44 is driven to rotate through the second chain wheel 45 and the second chain 46, the worm 44 rotates to drive the plurality of worm wheels 43 to synchronously rotate, and then the plurality of suction fans 42 synchronously rotate to suck air in the air pipe 7 from the lower part and blow the air into the machine tool shell 1.
One specific application of this embodiment is:
the invention mainly relates to the following processes when in use:
and (3) scrap blowing process: when machining is carried out, the movable door 3 is closed and sealed, the first motor 9 is started to drive one blowing fan 10 to rotate, the other blowing fan 10 is enabled to rotate synchronously through the cooperation of the first chain wheel 11 and the first chain 12 by the blowing fan 10, the high-speed rotating blowing fan 10 blows air above downwards to form strong air flow, and scraps on a workpiece and in a machine tool gap are blown down. The scraps fall on the bottom of the airport shell, one part of the scraps directly falls out of the first scrap discharge port 4, and the other part of the scraps falls on the inclined planes at two sides of the first scrap discharge port 4, and then slides into the first scrap discharge port 4 along the inclined planes. In the sweeps that fall out from the chip removal mouth can get into collection device 6, purging device 5 when blowing, because the oil gas that processing produced also can be blown to the below, the atmospheric pressure of purging device 5 top can reduce, and then makes upper portion tuber pipe 15 atmospheric pressure reduce, makes tuber pipe 7 have suction, makes oil gas get into middle part tuber pipe 14 from lower part tuber pipe 13, through oil suction device 8, with the oil absorption in the gas, at last through upper portion tuber pipe 15 reentrant lathe shell 1. The collection device 6 is sealed at the connection with the machine tool housing 1 in use.
Oil gas treatment process: the second motor 41 is started, the worm 44 is driven to rotate through the second chain wheel 45 and the second chain 46, the worm 44 rotates to drive the plurality of turbines 43 to synchronously rotate, the plurality of suction fans 42 are further driven to synchronously rotate, air in the air pipe 7 is sucked up from the lower part to be blown into the machine tool shell 1, and the air suction device 16 can further suck air in the lower air pipe 13 and the middle air pipe 14 into the upper air pipe 15 and then blown into the machine tool shell 1; the situation that the air pressure at the upper part of the blowing device 5 is not low enough, the suction force is not strong enough and the air in the air pipe 7 cannot flow from bottom to top is avoided. When the oil gas passes through the oil suction plate 36 from bottom to top, the oil in the oil gas is trapped, and the clean air continues to flow upwards. Because the sealing performance of the two ends of the air pipe 7 and the working space of machine tool machining is good, when oil gas is treated, air internal circulation is carried out, even if the oil gas is treated by the oil absorption plate 36, the oil gas still remains, the residual oil gas enters the air pipe 7 again after entering the working space of machine tool machining, and is treated by the oil absorption plate 36 again until the oil in the oil gas is completely absorbed, and after the workpiece is machined, the purging device 5 and the air suction device 16 can work again for a while, on one hand, sweeps the sweeps of the waste scraps are cleaner, and on the other hand, the oil gas is fully absorbed.
Oil suction plate 36 replacement process: the positioning pin 39 is matched with the positioning hole, so that the mounting disc 35 can be prevented from naturally rotating, when the oil suction plate 36 needs to be replaced, the positioning pin 39 is pulled upwards to be separated from the positioning hole, the second spring 40 is stretched, then the mounting disc 35 is rotated, the positioning pin 39 can be loosened when the oil suction plate 36 rotates at a small angle, when the new oil suction plate 36 rotates to the working position, the two positioning holes are overlapped, and the mounting disc 35 is fixed by the positioning pin 39.
