Summary of the invention
The purpose of this utility model provide a kind of can be fast under the situation of not cutting off the main shaft power supply drilling of bit change extension bar processing fast replacing drill chuck more.
To achieve the above object, the technical solution of the utility model is: a kind of drilling processing fast replacing drill chuck, comprise the main shaft extension bar, the drill bit extension bar, sleeve, has columniform public connecting portion on the described main shaft extension bar, one end of described public connecting portion offers one section blind hole along its direction of axis line, has the female connecting portion that matches with described blind hole on the described drill bit extension bar, described female connecting portion is inserted in the described blind hole, its circumferencial direction of described public connecting portion upper edge offers a plurality of through holes, described each through hole communicates with described blind hole respectively, be provided with ball in described each through hole, the outside wall surface of described female connecting portion is provided with groove a plurality of and described and that ball matches, be arranged with sleeve slidably on the described public connecting portion, at least has the clamp segment that one section bore attenuates on the described sleeve, when described clamp segment was positioned at the outer port part of described through hole, described ball partly was clamped in the described groove.
The outer circle wall of described public connecting portion one end is provided with the flange of outside protrusion, is fixed with back-up ring on the outer circle wall of described public connecting portion the other end, and described sleeve is between described flange and back-up ring.
Its circumferencial direction of described public connecting portion upper edge offers three through holes.
Be installed with drill bit on the described drill bit extension bar.
The utility model has the advantages that: fast replacing drill chuck of the present utility model uses simple, repeated cutting drilling machine power supply, these the cumbersome operations of repeated clamping drill bit have been avoided, can be under the situation of not cutting off main shaft extension bar power supply can be fast bit change extension bar more, saved the time of processing single products, thereby improve work efficiency of workers greatly, be fit to the batch machining product.
Description of drawings
Accompanying drawing 1 is front view of the present utility model (broken section);
Accompanying drawing 2 is the A-A cutaway view in the accompanying drawing 1;
Wherein: 1, main shaft extension bar; 11, public connecting portion; 111, blind hole; 112, through hole; 113, flange; 2, back-up ring; 3, sleeve; 31, clamp segment; 4, drill bit extension bar; 41, female connecting portion; 411, groove; 5, bolt; 6, ball; 7, screw; 8, drill bit.
The specific embodiment
A kind of drilling processing fast replacing drill chuck shown in Fig. 1~2, it comprises main shaft extension bar 1, drill bit extension bar 4, sleeve 3, has columniform public connecting portion 11 on the main shaft extension bar 1, one end of public connecting portion 11 offers one section blind hole 111 along its direction of axis line, has the female connecting portion 41 that matches with blind hole 111 on the drill bit extension bar 4, female connecting portion 41 is inserted in the blind hole 111, its circumferencial direction of public connecting portion 11 upper edges offers a plurality of through holes 112, each through hole 112 communicates with blind hole 111 respectively, be provided with ball 6 in each through hole 112, the outside wall surface of female connecting portion 41 is provided with a plurality of and the groove 411 that matches with ball 6, be arranged with sleeve 3 slidably on the public connecting portion 11, at least have the clamp segment 31 that one section bore attenuates on the sleeve 3, when clamp segment 31 was positioned at the outer port part of through hole 112, ball 6 parts were clamped in the groove 411.
The outer circle wall of public connecting portion 11 1 ends is provided with the flange 113 of outside protrusion, be fixed with back-up ring 2 on the outer circle wall of public connecting portion 11 the other end, be fixed on the public connecting portion 11 by bolt 5 during back-up ring 2, sleeve 3 can prevent effectively that like this sleeve 3 from slipping down from public connecting portion 11 between described flange 113 and back-up ring 2.
In the specific embodiment as figure, its circumferencial direction of public connecting portion 11 upper edges offers three through holes 112, and is evenly distributed on the circumference, and so corresponding ball 6 also has three, groove 411 also has three, fixes just drill bit extension bar 4 well can be fixed on the main shaft extension bar 1 by 3.
In when work, be installed with drill bit 8 on the drill bit extension bar 4, be fixed on the drill bit extension bar 4 by two screws 7 during drill bit 8, drill bit 8 can be changed model according to the difference of the diameter of machining hole certainly.
When this fast replacing drill chuck is installed, at first steel ball 6 is packed in three through holes 112, after be inserted in sleeve 3 on the public connecting portion 11 and make clamp segment 31 be positioned at the outer port part of through hole 112, to push down steel ball 6 like this, with bolt 5 back-up ring 2 and public connecting portion 11 are fixedly connected, again the main shaft extension bar 1 that connects is connected combination with drill press spindle, during use, drilling machine rotates, the operator is as long as slide sleeve 3 and make the part of ball 7 be clamped in the groove 411 along direction of axis line, have like this in the blind hole that is installed in main shaft extension bar 1 111 that the drill bit extension bar 4 of drill bit 8 just is fixed, the starter 8 of drill jig cover just can carry out drilling and processed on so direct cooperation frock.
When needs more during bit change extension bar 4, main shaft extension bar 1 is rotating always at this moment, at first sliding sleeve 3 makes ball 6 break away from groove 411, drill bit extension bar 4 just can take out in blind hole 111 like this, the new drill bit extension bar 4 that will change inserts in the blind hole 111, and sliding sleeve 3 makes clamp segment 31 be positioned at the outer port part of through hole 112, because main shaft extension bar 1 rotates, part ball 6 is just easily in the sliding recess 6, from being clamped in the groove 411 like this.
