And the end cap lock is fixed on the sinuous edge of the sleeve, and the gas flow passage is connected to the gas input passage of the sleeve; an air distribution distribution ring is received in the annular groove of the end cover, And a portion of the circumference of the air distribution distribution stop facing the gas flow passage is further provided with a cyclone groove; and a gas pressure source is disposed to communicate with the gas flow passage of the end cover. The gas is continuously input through the fluorine pressure source, and the gas enters through the sleeve, passes through the end cover, and finally forms a cyclone in the air distribution distribution ring and flows out through the gap, and the gas is continuously discharged to "can surely prevent the cutting fluid or The dust enters the inside of the spindle. Lu [Implementation] In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, please refer to the following [Simplified description of the drawings] for details: The creation of waterproof and dustproof processing machine A preferred embodiment of the main shaft, as shown in Figs. 2 to 4, comprises: a sleeve 20 having a hollow tube structure and having a connecting portion 21 at one end and an end portion 22 having a peripheral surface 221 at the other end. And one end edge surface 222, 4 M436524 and the sleeve 20 is extended along the axial direction X, and the vertical axial direction is a radial edge portion 22 which is provided with a milk composed of a first input object and a second input channel 232. The first input channel 231 is opened by the circumferential surface 22i in the radial direction γ, and the second input channel 232 is opened in the axial direction X and extends through the edge surface. The second wheel is further connected to the tunnel 232. One end of the first input channel 231 is further provided with a stop _ ^; a plurality of bearings 30 are disposed in the sleeve 2 ;; a shaft member 4G ′ is threaded to each of the yokes 30 in the sleeve 2Q, and the shaft member is 4〇 can pivot relative to the sleeve 20; - end cap 50, annular structure and has a through hole 5 One end of the end cover 5 is formed along the circumference of the through hole 51 to position the peripheral wall 52, and the other side is formed along the circumference of the through hole. The end cover 50 is opened by a surface on which the positioning peripheral wall 52 is disposed. 54. The gas flow passage 54 extends through the annular groove 53. The gas passage 54 is formed by the first flow passage 541 communicating with a second flow passage (10). The first L-flow passage 541 is opened along the axial direction X. The second flow channel 542 is inclined with respect to the radial direction γ, and the gas flow angle Θ1 is between the second flow channel 542 and the radial direction γ, and the gas output angle w is 3 b 45 degrees. The gas wheel exit angle θ 1 of the embodiment is 42 degrees, and the end cover 5〇 sleeves the shaft member 4〇 with the through hole 51, so that the inner circumference of the end cover 50 can block the shaft member 4〇. The sleeve 2 is disengaged, and the end cover is fixed to the end edge surface 222 of the sleeve 2, and the first flow passage 541 is communicated with the second input passage 232 of the sleeve 20, and the stop is stopped. The ring 24 is located at the intersection of the first flow channel 541 and the second wheel avenue 232, and the positioning peripheral wall 52 is interposed between the diagnostic member 40 and the sleeve 2〇; 5 5 M436524 a ring ring 6〇, a ring structure, the air distribution blocking ring (9) is received in the ring groove 53 of the end cover 5G' and the circumference of the airflow dividing ring 60 faces the position of the second flow channel 542. A cyclone 61 is disposed. The cyclone slot 61 is formed by a first sidewall surface 611, a second sidewall surface 612, and a bottom surface 613. The first sidewall surface 611 and the second sidewall surface 612 are respectively connected to the bottom surface 613. The first sidewall surface 611 is disposed along the radial direction γ. The bottom surface 613 is disposed along the axial direction, and the second sidewall surface 612 has a cyclonic angle between the radial direction γ and the angle of the cyclone is 15 to 30 degrees. The cyclone angle of the present embodiment is 3 degrees, and the second side wall surface 612 faces the second flow passage 542; and an air pressure source 70 is disposed to communicate with the first flow passage 541 of the end cover 50. The above is the structural relationship of the machine tool main body which can be waterproof and dustproof, and when the machining machine main shaft cooperates with the tool for cutting work, the air pressure source 70 is turned on, so that the air pressure source 70 continues to input the gas from the first input channel 231. Then, the gas passes through the first input channel 231, the second input channel 232, the first flow channel 541, and the first flow channel 542', and finally passes through the air circulation groove 61 of the airflow distribution blocking ring 6〇, and The air distribution distribution ring 60 and the end cover 5 are separated by a gap, and when the air pressure source 7 〇 continuously inputs the gas, the gas continuously flows out, and during the gas flow, when the gas follows the end cover 50 When the second flow passage 542 flows to the cyclone groove 61, the gas is output to the second side wall surface 612 by the gas output angle 0 of the second flow passage 542 and the second side wall surface 612 of the cyclone groove 61. A cyclone is formed in the cyclone 61. Finally, the homeward is separated by a gap between the air distribution distribution ring 6〇 and the end cover 5〇; thereby, the gas can be surely blocked by the gas or the cutting fluid due to the continuous gas discharge. Distributing the stop ring 60 by the air flow The gap between the end caps 5 enters the inside of the main shaft, which can prevent the internal components of the main shaft from being rusted or jammed. At the same time, since the gas flows through the gap after passing through the cyclone 61, if there is dust or cutting in the cyclone. When the liquid gas is swirled in the milk swirling groove 61 (4), it can be woven into the 61(10) dust or cutting fluid - and with φ ', the internal axis of the shaft can be cleaned and cleaned. According to the above description, 'this creation is not only the end cover 5 The air distribution distribution ring 6 〇 blocks most of the chips, cutting the shaft or the secret. It is continuously output by the gas, and it is sure that φ prevents foreign matter from entering the inside of the spindle, and the water and dustproof effect is indeed achieved.
