Description

Plug-in type wedge point withdrawing drill bit mechanism
Technical field:
The utility model is related to a kind of plug-in type wedge point withdrawing drill bit mechanism.
Background technology:
Drilling machine refers to that main drill bit processes the lathe in hole on workpiece.Usual bit is main motion, and drill bit is axially moved It is feed motion to move.Drilling machine simple structure, machining accuracy is relatively low, can holes drilled through, blind hole, change special tool, can expand, ream Hole, reams or carries out the processing such as tapping.Workpiece is motionless in process, allows cutter to move, by center cutter alignment hole center, and Rotate cutter;, it is necessary to when carrying out dismounting drill bit, how to unload drill bit is a troublesome thing after quite right drilling processing, Usual one hand of operator grips wedge point, and a hand grips hammer and taps wedge point, is extruded drill bit, but this kind of mode is not Only removal efficiency is low, and does not shield and sustain drill bit and be easily caused drill bit and drop and fracture, or even causes industrial accident.
The content of the invention:
The purpose of this utility model is to provide a kind of plug-in type wedge point withdrawing drill bit mechanism, and the plug-in type wedge point is taken out Pull out drill bit mechanism simple structure, reasonable in design, the security for being conducive to convenient operation and raising to use.
The utility model plug-in type wedge point withdrawing drill bit mechanism, it is characterised in that:Including hand-held overcoat and be located at it is hand-held Sliding inner sleeve in outer sleeve body, is provided with spring between the hand-held overcoat and sliding inner sleeve, the sliding inner sleeve end is provided with tiltedly Iron point, the wedge point is provided with the flange that can be clashed into hand-held overcoat end face near the end of sliding inner sleeve.
Further, above-mentioned hand-held overcoat rear end is provided with threaded cap, and the threaded cap inner face is provided with boss, the spring Overhead is between boss and the endoporus of sliding inner sleeve.
Further, above-mentioned hand-held outer putting is provided with groove long, and the sliding inner sleeve is provided with can be slided in groove long Position-limitting pin.
Further, above-mentioned wedge point is isosceles triangle flat ironware, and the flange on wedge point is perpendicular with it, And section is the circular arc for cutting off minor arc.
Further, above-mentioned hand-held overcoat end face is provided with the flange to be conducive to being clashed into flange.
Further, the maximum load of above-mentioned spring is 2 kilograms.
The method of work of the utility model plug-in type wedge point withdrawing drill bit mechanism, the plug-in type wedge point withdrawing drill bit Mechanism includes hand-held overcoat and the sliding inner sleeve being located in hand-held outer sleeve body, and bullet is provided between the hand-held overcoat and sliding inner sleeve Spring, the sliding inner sleeve end is provided with wedge point, and the wedge point is provided near the end of sliding inner sleeve can be with hand-held overcoat end The flange that face is clashed into;During work, one hand of operator grips hand-held overcoat, the drill bit on a hand gripping drilling machine, by wedge point Insert in the elongated hole of drill press spindle, now firmly hand-held overcoat exerts oneself to impact toward the tip of wedge point, hand-held overcoat end is hit Flange is hit, wedge point is constantly impacted the upper end of drill bit in elongated hole, drill bit can back and forth extruded several times.
In use, position-limitting pin is inserted with sliding inner sleeve, is slided with groove long;It is spacing when not using Pin is extracted, and hand-held overcoat is separated with sliding inner sleeve.
One hand of operator grips hand-held overcoat when the utility model is used, and the drill bit on a hand gripping drilling machine will be oblique In the elongated hole of iron point insertion drill press spindle, now firmly hand-held overcoat is exerted oneself to impact toward the tip of wedge point, hand-held overcoat end Portion's hits lip, makes wedge point constantly impact the upper end of drill bit in elongated hole, can back and forth extrude drill bit several times;Application method side Just, safety, efficiency high.
Brief description of the drawings:
Fig. 1 is profile of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the top view of hand-held overcoat;
Fig. 4 is the schematic diagram that hand-held overcoat is in extended configuration with sliding inner sleeve.
Specific embodiment:
