Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.
Referring to the attached drawings 1-3, the purging gun for the handheld machine tool comprises a gun body 1, wherein a through air inlet 11 and a purging pipe 12 are sequentially arranged at two ends of the gun body 1, and a control handle 13 for controlling the through and blocking of the air inlet 11 and the purging pipe 12 is arranged on the gun body 1. Connect the air supply through air inlet 11 for compressed air gets into in the rifle body 1, under the state of operation control handle 13, makes compressed air blow out from blowing pipe 12, sweeps fast the coolant liquid on the work piece, makes the coolant liquid on the work piece can quick return flow, clears up the work piece surface, is convenient for the work piece and dismantles the operation fast after the processing is accomplished. The blowing gun can blow the cutting waste residue around the workpiece.
In order to further improve the purging effect of the purging gun, a dispersing structure for uniformly purging the gas in the pipe body is arranged at the outer end port of the purging pipe 12. Can carry out effectual dispersion with the compressed air that sweeps in the pipe 12 through this dispersion structure to the area is swept in the increase, and then improves the clearance speed that sweeps of work piece surface coolant liquid, shortens the processing cycle of work piece, improves machining efficiency.
Specifically, as shown in fig. 2, the dispersing structure is a dispersing plate 2 detachably disposed in the port of the purging tube 12 (preferably, the dispersing plate 2 is in threaded connection with the purging tube 12, so that the purging tube 12 and the dispersing plate 2 can be cleaned after being detached), and the dispersing plate 2 is uniformly provided with dispersing holes 21. The purging pipes 12 are dispersed through the plurality of dispersing holes 21, the accumulation of compressed air on the surface of a workpiece is reduced, the purging area is increased, and the cleaning speed is accelerated.
In order to avoid the backflow of the cooling liquid during the purging process, each of the dispersion holes 21 is disposed to be inclined toward the edge of the dispersion plate 2. The arrangement structure enables compressed air blown out from each dispersion hole 21 to be blown out towards the outer side along the surface direction of the workpiece, the phenomenon of cooling liquid backflow can be effectively avoided, and the blowing area is further increased.
In order to enhance the purging effect of the purging gun, as shown in fig. 3, each of the dispersion holes 21 is formed in a tapered structure facing the outside of the port of the purging tube 12 (in fig. 3, the arrow c indicates the flow direction of the compressed air). When the compressed air in the purging pipe 12 enters the dispersion holes 21, the passing area of the compressed air is reduced through the conical structure of the dispersion holes 21, and then the circulating pressure of the compressed air is correspondingly increased, so that the pressure of purging to the surface of the workpiece is higher, and the cooling liquid on the surface of the workpiece can be rapidly purged.
Further, for the purging effect, the dispersion holes 21 are divided into a first group a and a second group b on the dispersion plate 2 in the radial direction, the dispersion holes 21 of the first group a and the dispersion holes 21 of the second group b are staggered in the circumferential direction, and a main blowing hole 22 is opened in the center of the dispersion plate 2. Firstly, the cooling liquid with the planar workpiece surface is blown out of the hole structure through the blowing holes 22, and then the holes are sequentially expanded outwards through the dispersion holes 21 of the first layer group a and the dispersion holes 21 of the second layer group b, so that the cooling liquid is quickly separated from the workpiece surface. The reason that the dispersion holes 21 of the first layer group a and the dispersion holes 21 of the second layer group b are arranged in a staggered mode along the circumferential direction is that the cooling liquid is in a liquid state and can be dispersed to two sides in the blowing process, and the dispersed cooling liquid can be effectively blown again through the dispersion holes 21 arranged in a staggered mode, so that the blowing speed is increased, and the blowing effect is improved.
The principle of the utility model is as follows: connect the air supply through the air inlet for compressed air enters into the rifle internally, under the state of operation control handle, makes compressed air blow off from blowing pipe, sweeps fast the coolant liquid on the work piece, makes the coolant liquid on the work piece can flow back fast, clears up the work piece surface, is convenient for the work piece and dismantles the operation fast after the processing is accomplished. The blowing gun can blow the cutting waste residue around the workpiece. Can will sweep intraductal compressed air through this dispersion structure and carry out effectual dispersion to the increase sweeps the area, and then improves the clearance speed that sweeps of work piece surface cooling liquid, shortens the processing cycle of work piece, improves machining efficiency.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
