Description
Technical field
This utility model relates to a kind of quick change spiral bit, belongs to mechanical drill technical field.
Background technology
Current quick change spiral bit includes cutter head, drilling rod, drillstock, and drillstock is designed as regular hexahedron, although this structure
It is capable of quick change at present and is also provided that certain axial limiting and circumference are spacing, but inconvenient operation when of dismounting, fixed
Position is unreliable, and this precision not only affecting processing workpiece also can reduce the service life of drill bit;Present drill bit is drilling rod and brill
Handle is directly connected to, owing to the reasons such as drilling rod smoother, drill bit are sharp easily injure workman, so loading and unloading drill bit when not
Convenient, reduce work efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of quick change spiral bit, to solve present existing spiral bit dismounting not side
Just, the problems such as unreliable, service life is short are positioned.
This utility model is realized by techniques below scheme: a kind of quick change spiral bit, including drilling rod 2, drillstock 3, dismounting dish
4;Drilling rod 2 one end is provided with cutter head 1, and dismounting dish 4 connection is arranged on drilling rod 2 other end, and drillstock 3 one end is provided with escape 5, drillstock 3
Being provided with annular groove 7, drillstock 3 is week side hexahedron structure, and 3 weeks sides of drillstock offer the circumferentially positioned hole of taper 6, taper week
Being evenly distributed on the hexahedron structure of drillstock 3 to hole 6, location, drillstock 3 one end is arranged on dismounting dish 4, drillstock 3 other end end
Offer taper in the middle of portion and axially position hole 8.
Described drillstock 3, the surface of annular groove 7 are crude.
The escape 5 of described drillstock 3 is identical with drilling rod 2 diameter, and escape 5 is smooth surface structure.
Deep 1.5~3.5 millimeters of described annular groove 7.
The operation principle of a kind of quick change spiral bit is: during use, puts into fixture with 4 drilling rods 2 of dismounting dish, passes through drillstock
The taper of 3 axially positions hole 8 and introduces, and drilling rod 2 axially can not go successively to fixture and annular groove 7 is axle when being clamped completely
Completing to spacing, completing of the circumferentially positioned hole 6 of drillstock 3 is circumferentially positioned.
This utility model has the advantages that
1, simple in construction, can realization degree is high, mechanism highly reliable;
2, may also provide good axial limiting while safe quick change being realized and circumference is spacing, and strengthen the anti-of drill bit
Fatigue strength;
3, manufacture, maintenance cost low, convenient maintenance, there is the strongest promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is drillstock end of the present utility model structural representation.
Figure is respectively numbered: 1: cutter head, 2: drilling rod, 3: drillstock, 4: dismounting dish, 5: escape, 6: the circumferentially positioned hole of taper,
7: annular groove, 8: taper axially positions hole.
