Specific embodiment
Further description is made to specific embodiment of the present utility model below in conjunction with attached drawing.
It is provided by Fig. 1 to Fig. 3, the utility model includes mandril 1 that is vertical and being able to rotate, and being set on mandril 1 can be upper and lower
Sliding and the annular slab 2 rotated with mandril 1 have the inside pin hole that is open on the medial surface on annular slab 2, and having in pin hole can be along pin
The fixture block 3 of hole sliding, has pressure spring in pin hole, pressure spring one end is connect with pin hole bottom, and the pressure spring other end is connect with fixture block 3；Mandril 1
On be provided with and be placed in vertical slot 4 with the fast one-to-one vertical slot 4 of card, 3 one end of fixture block, one end that fixture block 3 is placed in vertical slot 4 is oblique
The lower end in face, inclined-plane is drawn close to the axis of mandril 1, is had in vertical slot 4 multiple at wedge block 5 uniformly distributed up and down, fixture block 3 and wedge block
5 cooperate so that fixture block 3 slide downward but can be unable to upward sliding in vertical slot 4；
2 lower end of annular slab is fixed with the first cylinder 6 being sleeved on mandril 1, and the first cylinder is provided on 6 lower end surface
Multiple first notches 7 have cross bar in first notch 7, and cross bar one end is hinged in the first notch 7, and the other end of cross bar is to mandril 1
Axis extend, cross bar is fixed with vertical bar below one end of 1 axis of mandril, cross bar and the at L-shaped bar 8 of vertical bar group, under vertical bar
End is fixed with blade 11, the second cylinder 9 is set in the first cylinder 6,9 upper end of the second cylinder and annular slab 2 are fixed, the second cylinder
9 lower ends are provided with multiple second notches 10 corresponding with the first notch 7, and 1 lower end of mandril heads on L shape bar 8 when annular slab 2 moves up
Rotation makes vertical bar tend to the outside that horizontal and blade 11 is placed in the second cylinder 9.
The maximum gauge of the annular slab 2 is greater than the diameter of the second cylinder 9.
In order to facilitate withdrawing, the fixture block 3 is fixed with the pull rod along 2 diameter of annular slab far from 1 axis one end of mandril, draws
Bar is through pin hole bottom and is placed in the outside of annular slab 2, and pulling shaft be placed in annular outboard one section has annular protrusion.
In order to install blade 11, there is swaging clamp slot in the vertical bar lower end, has housing screw on blade 11, has and press in guide groove
The corresponding threaded hole of tight screw, housing screw are fixed through threaded hole and vertical slot 4.
In order to enable annular slab 2 automatically replies original state, the mandril 1 is on the part of 2 top of annular slab and is fixed with
Circular slab 12 is set with pressure spring on mandril 1, and pressure spring upper end is connect with circular slab 12, and pressure spring lower end is connect with annular slab 2.
It is worth noting that, the connection of mandril upper end is dynamic, on the main shaft of class such as drilling machine, so that main shaft drives on mandril 1
Lower movement or rotation；The diameter in the hole processed is between 2 maximum gauge of 9 diameter of the second cylinder and annular slab；It is processed
Hole be through-hole, and the depth in hole is less than the diameter of the second cylinder 9, and the first notch 7 has torsional spring with the hinged position of cross bar.
The second cylinder 9 is set to insert in the hole from top to bottom in use, mandril 1 moves down, when the lower end face contact of annular slab 2
When to hole, since the diameter in hole is less than the maximum gauge of annular slab 2, annular slab 2 cannot be moved down, at this time mandril 1 continue to
Lower movement, 1 lower end of mandril head on L shape bar 8 down and L shape bar 8 are rotated, and L shape bar 8 rotates so that blade 11 is placed in the second cylinder
9 outsides, the at this time stopping of mandril 1 move down；At this point, use drill press spindle drive mandril 1 rotation and at the same time make mandril 1 to
Upper movement, since wedge block 5 sticks fixture block 3, so, annular slab 2 also follow vertical pivot move up, annular slab 2 with cutter to
Upper movement, blade 11 will go out platform in the lower end ream in hole.
When withdrawing, it need to only pull pulling shaft that fixture block 3 and wedge block 5 are detached from, pressure spring moves down annular slab 2, most
Whole L shape bar 8 restores to the original state, and can easily take out the present apparatus at this time.
In above process, during the work time, L shape bar 8 is in the first notch 7 and the second notch 10 blade 11, is had
The intensity for increasing L shape bar 8 of effect, effectively increases service life.
