Abstract
The invention discloses a kind of rotary drilling-head for numerical controlled engraving and milling device, including handle of a knife and cutter head, the handle of a knife and cutter head are detachably connected, the cutter head is made up of four pieces of blades, respectively blade one, blade two, blade three, blade four, the blade one and blade three, blade two and blade four are symmetrical on cutter head center.By the connection of cutter head and blade, the modularization of away drill cuttings is realized, when drill bit fracture occurs or damages, it is only necessary to change the blade of chisel edge part, save drill bit cost while also extending the service life of drill bit.
Description
Technical field
The present invention relates to mechanical field, the more particularly, to rotary drilling-head of numerical controlled engraving and milling device.
Background technology
Carving and milling machine is a kind of rotating speed high, the efficient cold working equipment of feed high, it is used for small cutter, retrofit, it is generally acknowledged that carving and milling machine is to use small cutter, the CNC milling machine of high-power and high-speed main spindle motor, foreign countries do not have the concept of carving and milling machine, processing mold they be based on machining center milling, but machining center has its deficiency, particularly can seem unable to do what one wishes when with small tool sharpening small mould, and cost is very high, there was only the concept of digital-controlled carving machine at first in the country, the advantage of engraving machine is in carving, if rapidoprint hardness can also seem unable to do what one wishes than larger, the appearance of carving and milling machine is it may be said that filled up blank between the two, carving and milling machine can both be carved, also can milling, it is a kind of efficiently high-precision Digit Control Machine Tool.But existing carving milling apparatus are still present many technical deficiencies, for example carving and milling machine rotary drilling-head in actual use, due to carry out drill for high-speed and workpiece it is easy between generate heat drilling, easily cause bit damage, cause its drilling life of bit not long.
The content of the invention
The invention aims to solve the problems, such as to be previously mentioned in above-mentioned background technology, there is provided a kind of rotary drilling-head for numerical controlled engraving and milling device.
To achieve these goals, technical scheme is as follows：
A kind of rotary drilling-head for numerical controlled engraving and milling device, including handle of a knife and cutter head, the handle of a knife and cutter head are detachably connected, the cutter head is made up of four pieces of blades, respectively blade one, blade two, blade three, blade four, the blade one and blade three, blade two and blade four are symmetrical on cutter head center.
Further, helicoid has been correspondingly formed between the blade one and blade two, blade three and blade four, cooling bath has been provided with described two helicoids, described two helicoids, two cooling baths are each symmetrical on cutter head center.
Further, the pitch of the helicoid is set to 100mm.
Further, the handle of a knife is connected with the cutter head using fastened by screw.
Compared with prior art, beneficial effects of the present invention are as follows：
Provided by the present invention for the rotary drilling-head of numerical controlled engraving and milling device, including handle of a knife and cutter head, its handle of a knife and cutter head are detachably connected, its cutter head is made up of four pieces of blades, blade one and blade three, blade two and blade four are symmetrical on cutter head center, rotary drilling-head for numerical controlled engraving and milling device of the invention, by the connection of cutter head and blade, realize the modularization of away drill cuttings, when there is fracture or damages in drill bit, only need to change the blade of chisel edge part, in addition, its blade one of the invention and blade two, helicoid has been correspondingly formed between blade three and blade four, cooling bath is provided with two helicoids, two helicoids, two cooling baths are each symmetrical on cutter head center, it is easy in drilling process, can cool down in time, so as to improve drilling quality, the service life of drill bit is also extended simultaneously.
Brief description of the drawings
Technical scheme in order to illustrate more clearly the embodiments of the present invention, the accompanying drawing to be used needed for being described to embodiment below is briefly described, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, without having to pay creative labor, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of cutter head in the present embodiment.
Fig. 2 is the top view of cutter head in the present embodiment.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Specific embodiment：
A kind of rotary drilling-head for numerical controlled engraving and milling device with reference to shown in Fig. 1, Fig. 2, including handle of a knife and cutter head, handle of a knife and cutter head are detachably connected, cutter head is made up of four pieces of blades, respectively blade 1, blade 22, blade 33, blade 44, blade 1 and blade 33, blade 22 and blade 44 are symmetrical on cutter head center.
In the present embodiment, for the rotary drilling-head of numerical controlled engraving and milling device, by the connection of cutter head and blade, the modularization of away drill cuttings is realized, when drill bit fracture occurs or damages, it is only necessary to change the blade of chisel edge part.
In addition, in the present embodiment, helicoid has been correspondingly formed between its blade 1 and blade 22, blade 33 and blade 44, cooling bath 5 is provided with two helicoids, two helicoids, two cooling baths 5 are each symmetrical on cutter head center, and its cooling bath 5 is connected with the atomising mechanism of numerical controlled engraving and milling device, it is easy in drilling process, atomization type can cool down in time, so as to improve drilling quality, while also extending the service life of drill bit.
In the present embodiment, the pitch of helicoid is set to 100mm.
In the present embodiment, handle of a knife is connected with the cutter head using fastened by screw, and in actual applications, user can be according to different drilling workpiece, according to handle of a knife and the tightness of cutter head, using other connection fastening means.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, all any modification, equivalents made within the scope of the present invention etc. should be included within the scope of the present invention.
