Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Embodiment: a kind of fluted drill with im-pact location hole function, as shown in accompanying drawing 1 ~ 3, including housing 1, spiral bit 2 and electric machine main shaft 3, it is installed on the chuck component 4 of housing 1 leading section, the clip tooth face 41 being positioned at chuck component 4 front portion is clamped with spiral bit 2, chuck component 4 rear portion clamps described electric machine main shaft 3 by main spindle multiple spline groove 5, and its rotary torsion is passed to described chuck component 4 by main spindle multiple spline groove 5 by electric machine main shaft 3, thus drives spiral bit 2 to rotate；Having bullet 33 between front portion 31 and the rear portion 32 of described electric machine main shaft, an elastomer 6 is between housing 1 rear portion and impact ring 8, and a middle sliding sleeve 7 is set on electric machine main shaft 3 and between described impact ring 8 and chuck component 4 rear end face；Described middle sliding sleeve 7 front end is provided with block 71, this middle sliding sleeve 7 external diameter is more than the anterior diameter of described electric machine main shaft 3 less than described impact ring 8 internal diameter and its internal diameter, described middle sliding sleeve 7 promotes described impact ring 8 compresses elastomeric 6 along bullet surface when moving, when the middle rear end of sliding sleeve 7 coincide with the through hole of described impact ring 8, impact ring 8 clashes into the block 71 of middle sliding sleeve 7, thus is driven spiral bit 2 preshoot by chuck component 4.
Specific works process is as follows: shown in accompanying drawing 1, and when original state, a middle sliding sleeve 7 is positioned at the front portion of electric machine main shaft, and now the axial line of middle sliding sleeve 7 is positioned at below the axial line of electric machine main shaft 3,
When spiral bit 2 is pressed on band machined surface by operator, spiral bit 2 retraction is moved after promoting chuck component 4, chuck component 4 promotes middle sliding sleeve 7 to move along bullet 33 surface again, in the middle of time mobile, the axial line of sliding sleeve 7 moves closer to the axial line of electric machine main shaft 3, when in the middle of both axial line coincidences i.e., the rear end of sliding sleeve 7 coincide with the through hole of described impact ring 8, then it is in the pre-of accompanying drawing 2 and rushes state, now elastomer 6 stores energy, as shown in Figure 3, impact ring 8 clashes into the block 71 of middle sliding sleeve 7, thus is driven spiral bit 2 preshoot by chuck component 4.
Above-mentioned chuck component 4 inwall has projection 42, one bolt 9 is between described electric machine main shaft 3 and spiral bit 2, the screw rod 91 of this bolt 9 is installed on electric machine main shaft 3 end, a gap 10 embedded for projection 42 is left in head 92 and electric machine main shaft 3 end of bolt 9, and the projection 42 of described chuck component 4 can move left and right along gap 10.Above-mentioned elastomer 6 is spring.
To sum up, during the fluted drill with im-pact location hole function of above-mentioned embodiment uses, it is not necessary to change instrument, directly can complete to go out a whole set of actions such as location hole, fluted drill centering, boring, both improve operating efficiency, be also beneficial to precision and the Quality advance of boring.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
