And can make the end of the airway 543 just connect Located at the inlet port 52 2 so that air can flow through the first shaft hole 5 4 6 through the second shaft hole 5 4 6 outside, the suction port 5 4 7 outside and the inlet port 5 2 2 through the air passage β 4 3 through the first shaft hole 5 4 5 Then, it flows into the air chamber 5 24 4; the grinding wheel 5 5 is assembled on the driven shaft 34 and is located outside the spacer element 5 4; the outer cover 5 6 is appropriately disposed There are a plurality of perforations 5 6 1 , curved strips of the limiting piece 5 6 2 , a notch 5 6 3 and a pressing piece 5 6 4 , wherein the limiting piece 5 6 2 is located on the inner surface of the outer cover plate 56 The outer side is convexly protruded, and the notch 563 is located on the limiting piece 526, and a wedge-shaped pressing piece 546 is formed on the outer cover 65 to protrude inwardly. After the locking member 82 is inserted into the through hole 56 1 and locked to the lower half of the outer casing 5 2 , an outer chip collecting portion 9 is formed between the outer casing 5 2 , the separating member 5 4 and the outer cover 56 , and The end of the grinding wheel 5 5 which has been assembled on the 4 - end of the driven shaft 3 can be rotated therein (ie, the end of the grinding wheel 5 5 - is located between the M353065 side of the spacer element 5 4 and the outer cover 5 6 ), and by the inwardly protruding sheet 5 The spacing between the 6 4 and the grinding wheel 5 5 is minimized, and an effective upward discharge resistance or wind pressure is generated, thereby forcing most of the gas to flow into the air chamber 5 as the guide piece 504 acts. 2 4; When it is desired to perform the grinding process, the motor 3 1 must be started to rotate, and the motor 31 is forced to transmit its power to the driven wheel 3 3 via the driving wheel 3 2 and the transmission belt 35, and via The rotation of the driven wheel 3 3 drives the shaft cup 3 4 to rotate, thereby driving the lower drum 2 4 , the fan element 5 3 and the grinding wheel 5 5 which are assembled on the driven shaft 3 4 to be synchronized. Rotating; at this time, since the fan member 53 is rotated in the recessed air chamber 524 formed between the housing base 52 and the spacer member 54 and approaching the near-closed state, the fan of the fan member 53 is caused. 5 3 1 The maximum wind pressure formed near the outer side will flow directly into the main exhaust hole 5 2 6 and the secondary exhaust hole 5 2 7 ', and most of the gas is formed through the human air vent 5 2 6 and then through the row The gas ♦ tube 5 7 is discharged to the outside of the susceptor group 1, and at the same time, some of the gas is also pressurized. After the vent hole 5 2 7 , the column 5 Q 2 can be sprayed toward the receiving area 5 and the outlet end 503 via the tube 5 1 and the column 5 G 2 of the chip holder β 0 . And then the gas can flow directly into the air inlet 5 2 2 of the outer casing 5 2 , and sequentially, after the air inlet 5 2 2 , the air passage 5 4 3 and the first shaft hole 5 4 5 The fan piece 53 1 near the center of the fan element 53 in the near-closed plenum 52 is rotated to form an amount of attraction - so that the gas can pass through the 11 M353065 first shaft hole 5 4 5 is sucked into the fan blade 53 1 near the center of the fan member 533, and is smashed by the centrifugal force to vent the gas to the circumferential side of the plenum 52, and finally, most of the gas can be obtained. Directly flowing into the main exhaust hole 5 2 6 and then discharged to the outside of the base group 1 via the exhaust pipe 57; At this time, if the workpiece is to be placed on the abrasive belt 25 for grinding, it will be ground. The workpiece in the workpiece generates debris dust, and the debris dust is sprayed toward the limit guide 26 until the debris dust hits the limit 2 6 5 • In order to prevent the debris dust from changing the flow direction of the restricted portion 265, and sequentially passing through the hole 2 6 ii of the limit guide 26, the through space 41 of the rear block 4, After the communication hole 1 5 2 of the base group 1, it falls into the receiving area 50 1 of the chip holder 50; at this time, the receiving area 5 is received by the column 5 0 2 toward the outlet end 5 The gas ejected in the direction of 3 is guided, so that the gas and the debris dust can flow directly into the air inlet 522 of the outer casing 5, and sequentially flow through the air inlet 5 2 2, the air passage 54 • 3 And after the first shaft hole 5 4 5 ' is subjected to the attraction force formed by the rotation of the fan element 53 3 near the center, so that the gas and the debris dust can pass through the first shaft hole 545. It is sucked into the air chamber 524, and the gas and the debris dust are smashed to the gas through the centrifugal force of the fan π-piece 5 3 to flow to the gas chamber 5 24, and finally, In order to allow most of the gas and debris dust to flow directly into the main exhaust hole 5 2 6 and then discharged to the outside of the base group 1 through the exhaust %* 5 7 Dust removal efficiency; 12 M353065 If the workpiece is to be ground on the grinding wheel 5 5, it will cause the workpiece in the grinding to generate debris dust, and the debris dust will face the outer Z plate 5 6 inside Spraying until the debris dust hits the limiting piece 5 6 2 can cause the debris dust to restrict the blocking of the bit piece 5 6 2 and flow toward the guiding piece 5 44 of the spacer element 5 4 , and By the guiding action of the guide piece 524, and causing the suction port 5 4 7 that has flowed to the position of the transfer between the guide piece 544 and the air passage '54 and the first shaft hole 545, The suction force formed by the rotation of the fan element 53 in the near-closed air chamber 52 is close to the center, so that the gas and the debris dust are sucked into the first shaft hole 545. In the gas chamber 524, and through the centrifugal force of the fan element 5 3, the gas and the debris dust are thought to flow to the gas chamber 5 2 4 side and flow in the direction of the gas chamber 5 24 , and finally, Most of the gas and debris dust can flow directly into the main exhaust hole 5 2 6 and then through the exhaust pipe 57 Out of the outer side of the pedestal group 1, and achieve the effect of collecting Φ dust and chip removal; comprehensively, the sand dust collecting structure of the sanding machine of the present invention is improved, and it has an unprecedented innovative structure, which is not found in any publication. And there is no similar product on the market, so its novelty should be undoubted. In addition, the unique features and functions of this creation are far from being comparable, and it is indeed more progressive than the conventional structure. It meets the requirements of the application requirements for new patents in the Chinese Patent Law. 13 M353065 [Simple description of the diagram]: The diagram is a schematic diagram of the continued decomposition of the abstract; 3: The three-dimensional partial decomposition of the first diagram is enlarged; - ',: the partial combination of the creation.
