Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of down-the-hold drill bit Special quenching frame, comprising:
Chassis 1 comprising the bottom frame 101 of rectangle frame-shaped and the grid 102 being laid in the bottom frame 101；
Side frame, there are two, it is separately positioned on two long margin frames of bottom frame 101, for wherein each side frame, includes
Along three vertical bars 2 straight up of length square spacer setting and three are secured transverse on the long margin frame of bottom frame 101
A link 4 is respectively arranged in the mandril 3 on 2 top of vertical bar, the two sides of mandril 3；
Fixed device comprising the length direction along mandril 3 is sequentially distributed in the plane common to the mandril 3 on both sides
It is multiple, it include first support bar 5, second support bar 6 and two arc panels 7 for wherein each fixed device, first
Strut 5 and second support bar 6 respectively the inner vertical of the mandril 3 of two sides fix and the two towards each other, two arc panels 7 divide
It is not fixed on the front end of first support bar 5 and second support bar 6 and opening towards each other, first support bar 5 is by two sections of quarter butts
And the spring 8 being connected between two sections of quarter butts collectively constitutes；
Pull rod 9 is arranged in parallel in inside and the mandril 3 of the mandril 3 connecting with first support bar 5, and by each first
Quarter butt series connection in support rod 5 close to 7 side of arc panel is integrated.
The quenching frame when in use, is held pull rod 9 and is clutched to the direction of mandril 3, then the compression of spring 8 makes first support bar 5
The arc panel 7 of upper connection expands the space between two arc panels 7, the drilling tail court of down-the-hold drill bit far from another arc panel
It is inserted between two arc panels 7, the bottom of final drilling tail is shelved on the grid 102 being laid on bottom frame 101, then loose
Pull rod 9 is opened, spring 8 restores the arc panel 7 that deformation drive is connect with first support bar 5 and resets, will together with another arc panel
The drilling tail of down-the-hold drill bit wales fixation and catches on the link 4 on mandril using suspender after down-the-hold drill bit is fixed on quenching frame,
Then down-the-hold drill bit is put into hardening media with quenching frame and is quenched.Place down-the-hold drill bit on the quenching frame, one
The bottom of aspect, drilling tail is supported by grid 102, the stress point of drilling tail bottom is increased while not interfering bottom to quench, no
Flaw easily is formed in drilling tail bottom, on the other hand, when drilling tail is put into downward, because the space between two arc panels 7 can expand
It places into, does not easily cause the scratch of drilling tail side wall, and two arc panels 7 are tightened and can equally fix drilling and bore after being put into
Head can prevent the shaking and mutually collision of drill bit.
In another embodiment, two arc panels 7 be the length that is cut down on the same annular slab it is identical two sections and
The diameter of the annular slab is identical as the diameter of down-the-hold drill bit drilling tail part.It on the one hand ensure that the radian and brill of arc panel 7 in this way
The radian on tail surface coincide, more firm after down-the-hold drill bit is fixed, on the other hand, when spring does not compress, two 7 institutes of arc panel
The diameter of a circle surrounded is just identical as the diameter of drilling tail, then arc panel 7 will not apply drilling tail surface after drilling tail is fixed
Pressure is avoided and is weighed wounded, if but drill bit topple over and to deviate between two arc panels 7, need to overcome the elastic force of spring, because
This, which is in turn ensured, can fix drill bit.
