Detailed Description
The invention will be further described with reference to the accompanying drawings and examples. It should be noted that the examples are given solely for the purpose of illustrating the invention and are not to be construed as limiting the invention, including the figures, which are given solely for reference and illustrative purposes and do not constitute limitations on the scope of the invention, since many variations thereof are possible without departing from the spirit and scope of the invention.
As shown in fig. 1-3.
A dust hood with an external blowing structure comprises a hood body 1, an air nozzle 2, an air nozzle box 3, an air source controller 4 (such as an electromagnetic valve), an air pipe 5 and an air nozzle seat 6, wherein as shown in figure 1, the hood body 1 is connected with a vacuum pump (not shown in the figure, the installation position can be freely configured according to the actual condition of a machining center, and the installation position is not limited in the figure), and the vacuum pump can generate vacuum at the top of the hood body and is used for sucking away wood chips; the air nozzle 2 is arranged on the air nozzle seat 6, and air is blown out of the air nozzle 2; the air nozzle box 3 is fixed on the cover body 1 and is used for placing the air pipe 5 and the air nozzle seat 6; the gas source controller is used for controlling the on-off of gas in the gas nozzle 2; each air nozzle seat 6 is connected with the air source controller 4 through the air pipe 5 by the air pipe 5 for air guiding, and as shown in fig. 2, the air source controller 4 supplies air by an air source (an air pump, an air storage tank and the like); the air nozzle seat 6 is arranged on the air nozzle box 3 and used for fixing the air nozzle 2 and guiding air.
Specifically, 2 materials of air cock are the aluminum alloy, and air cock 2 is long slightly and have certain camber, and the air cock head is in the brush outside, to main shaft cutter, add man-hour, by control system (can directly generate on the machining center, also can design and manufacture by oneself, control software also can utilize prior art to compile by oneself) control closing and closing of air cock 2, blow with the air cock 2 of the relative direction of the smear metal speed of saw-dust, other air cocks 2 then can be closed, when the clean mesa of needs, then steerable whole air cocks are opened, clean with the mesa with the fastest speed.
Specifically, the number of the air nozzle seats 6 is four, the air nozzle seats 6 are symmetrically distributed around the main shaft, are respectively fixed on the air nozzle box 3 through screws and are uniformly distributed on the feed-x、+x、-y、+yIn four directions, each air nozzle seat 6 is provided with an air hole for installing the air nozzle 2, and a rubber pad is matched for preventing air leakage during installation.
The working principle of the present invention is as follows, and is explained with reference to fig. 3(a), (b), and (c):
when the tool is cutting, the cutting chips are along the tangential direction of the rotating direction of the toolv 1 The air nozzle moving at high speed in the direction opposite to the movement direction of the wood chips begins to give off air, namely the flow direction of the air current is opposite to the movement direction of the chips, and the high-speed air current is blown out from the air nozzlev 2 To reach the processing table, and to be reflected with the processing table to become the speedv 2 ’With a high velocity air stream of moving chips at a velocity ofv 2 ’High speed ofAction of air flow, horizontal component velocity of air flowv 2x ’With speed of wood chipsv 1 Mutually offset, so that the movement speed of the wood chips is greatly reduced, and the vertical component speed of the air flowv 2y ’Raising wood chips and sucking the wood chips in a dust hoodv 3 Under the combined action of the two components, the wood chips have upward speedvThe sawdust is sucked away by the cover body 1. If the air tap does not blow, it can be seen that the suction speed direction of the cover body 1v 3 In the direction of movement of the wood chipsv 1 The closing speed is very small along the upward component speed, so that the sawdust is not sucked away, when the air nozzle starts to blow air, the closing speed is very large along the upward component speed, and the sawdust is sucked away.
The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be equivalent replacement modes, and all are included in the scope of the present invention.
