Description
Technical field
The utility model is related to drilling machine auxiliary equipment field, more particularly to drilling machine drill bit device.
Background technology
At present, known Quick replaceable drill bit by：Fixed drill holder, slip cutting ferrule, cylinder Quick diameter changing sleeve are combined.When
When changing another cutter, drill press spindle is lifted, when cutter leaves workpiece, a hand pushes up slip cutting ferrule, another
Hand is loaded into while cylinder Quick diameter changing sleeve is removed in the cylinder Quick diameter changing sleeve that will be equipped with another cutter,
Cutting ferrule will be slided to push down on be allowed in place and block.Though this Quick replaceable drill bit can realize quick change but troublesome poeration, time-consuming, transmission
Moment of torsion is small, loses drilling machine power, only adapts to small-diameter cutter and uses.When fixed drill holder is removed, it is necessary to by wedge and bulky
Head beats and can just exit, and this method is easily damaged cutter and drill holder, directly influences the precision and service life of drilling machine.
Utility model content
The purpose of this utility model is a kind of new fast assembling-disassembling drill bit device of exploitation.
The utility model is realized by the following technical solutions：
A kind of fast assembling-disassembling drill bit device, including collet body, are provided with hollow hole portion in the collet body, also wrap
Include：
Spring chuck, the spring chuck is socketed in the hollow bore portion of collet body；
Elastic conical drogue, is socketed in spring chuck, for coupling drill bit；
Lock sleeve, turn is arranged on the outer surface of collet body；
Steel ball, is arranged in the pin-and-hole of connection collet body and spring chuck；
Check ring, is arranged on the outer surface of collet body, for limiting locking set.
Further, described lock sleeve one end is provided with opening half slot.
Further, the check ring is set to 2, is separately positioned on the two ends of collet body.
Further, the lock sleeve turn is arranged between 2 check rings.
Compared with prior art, the utility model is provided with pin-and-hole on the external cylindrical surface of collet body, and pin-and-hole is connected always
To the face of cylinder of spring chuck, but do not penetrate spring chuck inner surface, steel ball placed in pin-and-hole, by steel ball couple collet body with
Spring chuck, transmitting torque is big；Additionally, the end of lock sleeve is provided with opening half slot, by turn lock sleeve, it is convenient to
Take out and placement steel ball, reach the purpose of drill bit fast assembling-disassembling, the drill bit compared with prior art changes the outfit, and improves nearly 1/4 effect
Rate.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Wherein：1st, collet body, 2, check ring, 3, lock sleeve, 3a, opening half slot 4, steel ball, 5, spring chuck, 6, bullet
Property tapered sleeve, 7, drill bit.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described further to the utility model.
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model, is not used to limit the utility model.
As shown in figure 1, present embodiment discloses a kind of fast assembling-disassembling drill bit device, including collet body 1, the one of collet body 1
End is taper shank, and the other end is centrum portion, and hollow hole portion is provided with centrum portion；Also include：Spring chuck 5, in cylinder knot
Structure, spring chuck 5 is socketed in the hollow bore portion of collet body 1；Elastic conical drogue 6, is socketed in spring chuck 5, elastic conical drogue 6
The other end be used for couple drill bit 7；Lock sleeve 3, turn is arranged on the outer surface of collet body 1, and particular location is in the outer of centrum portion
On the face of cylinder；Steel ball 4, is arranged in the pin-and-hole of connection collet body 1 and spring chuck 5, and pin-and-hole penetrates collet body 1, but does not penetrate
Spring chuck 5, steel ball is placed between collet body 1 and spring chuck 5, for transmitting moment of torsion therebetween；Check ring 2,
The present embodiment provides the example for setting 2, is separately positioned on the two ends of collet body 1, for lock sleeve 3 in locking position and dismounting position
When positioning.
In the present embodiment, the one end of lock sleeve 3 is provided with opening half slot 3a, is easy to being placed and taken out for steel ball 4.
When the utility model is used, turn lock sleeve 3 makes lock sleeve 3 be moved along taper shank, and when opening, half slot 3a is just right
When pin-and-hole, when that is to say steel ball 4, now, the end of lock sleeve 3 contacts with check ring 2, now, can be taken off steel ball or puts
Enter steel ball 4, for the dismounting and installation of drill bit 7；Conversely, after drill bit 7 is installed, opposite direction turn lock sleeve 3 presses lock sleeve 3
Firmly steel ball 4, that is, realize that the normal of the device is used.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, naturally it is also possible to design the long bolt of other quantity, as long as can be in the base of above-described embodiment without creative work
The technical scheme realized on plinth, is regarded as falling into the rights protection scope of the utility model patent.
