Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
Embodiment 1: referring to Fig.1, a kind of round shaft chisel quick-speed jigs, including 1, five collet 2 of columned clamp body,
A clamping hole 11 for placing circle shaft chisel is equipped at the axle center of clamp body 1, clamping hole 11 is surrounded by five cunnings radially
Slot 12, sliding slot 12 are uniformly distributed circumferentially, and the front end of sliding slot 12 is communicated with clamping hole 11, and the rear side of sliding slot 12 is equipped with atmospheric pressure cavity
13, the axial line of atmospheric pressure cavity 13 and the axial line of sliding slot 11 are in together in a radial alignment, and five collets 2 are one-to-one respectively
Setting is slidably matched in sliding slot 11 with sliding slot 11, is equipped with spring 3 in the rear portion of collet 2 in sliding slot 11, is equipped in atmospheric pressure cavity 13
One mandril 4, mandril 4 are slidably matched with atmospheric pressure cavity 13, and the front end of mandril 4 extends to the rear portion of spring 3 and connects with the rear end of spring 1
It connects, is equipped with the air pressure storehouse 14 of an annular communicated with multiple atmospheric pressure cavities 13, fixture on clamp body 1 corresponding to the rear portion of atmospheric pressure cavity 13
Body 11 be equipped with to 14 injecting compressed air of air pressure storehouse gas nozzle 15, by gas nozzle 15 into air pressure storehouse 14 injecting compressed air,
Enterprise increases in air pressure storehouse 14, synchronous with the air pressure in the atmospheric pressure cavity 13 of 14 cabinet of air pressure storehouse to increase, atmospheric pressure cavity air pressure increase top
Dynamic mandril travels forward, and mandril 4 squeezes forward spring 3, and spring 3 then squeezes collet 2 and moves into clamping hole 11, compression tightly
On circle shaft chisel in clamping hole, the clamping to circle shaft chisel is realized, increase since five atmospheric pressure cavity air pressures are synchronous, realize
The synchronous Forward of five collets compresses, and both plays clamping action to circle shaft chisel, also acts as Self-centering Action, improves circle shaft chisel
Machining accuracy, cylindrical clamp body in lathe, is convenient to use this fixture convenient for clamping, and pressure control clamps, ventilation
While clamping to circle shaft chisel can be realized, the efficiency of clamping significantly improves, and it is convenient to operate, the compression of air pressure force pushing mandril
A part of atmospheric pressure is converted into the spring force of spring by spring, the power being ultimately applied on round shaft chisel include spring elastic force,
The atmospheric pressure of a part ensure that the clamping dynamics to circle shaft chisel, partial gas pressure power are converted into the elastic force of spring, have buffering
Property, the moment impact of air pressure is avoided, collet is avoided to cause impact damage to circle shaft chisel, and after being converted into elastic force, is had more
The vitality of good power makes the stationarity output of clamping force more, improves the clamping effect of circle shaft chisel, atmospheric pressure cavity 13 and air pressure
The rear end that storehouse 14 connects is pyramidal structure, and the biggish one end of pyramidal structure connects with air pressure storehouse, and pyramidal structure has poly- pressure effect,
Increase pressure, pressure is promoted to assemble to atmospheric pressure cavity, improve and compress effect, the front end of collet 2 is arc or V-structure, both may be used
It coincide with circle shaft chisel circumferential surface, and the clamping force to cutter can be improved, improve clamping effect, collet movement range is big, is suitable for
The clamping of the circle shaft chisel of different size, fixture can clamping various outer diameter cutter, reduce the investment of production.
Mandril 4 is I-shaped structure, and the rear end of mandril 4 is the cylindrical pushing part coincideing with 13 structure of atmospheric pressure cavity, mandril 4
Front end be the cylindrical butting section being resisted against on spring, be the body of rod among butting section, pushing part, butting section, pushing part it is outer
Diameter is all larger than external diameter of rod body, and the area at I-shaped structure both ends is big, improves the stationarity of mandril movement, improves gas pressure in pushing away
Motive force in dynamic portion improves butting section and acts on the active force on spring, promotes to improve pressing force, corresponding sliding slot 12 and air pressure
A connecting cavity 16 being slidably matched with 4 shaft of mandril is equipped between chamber 13, convenient for cooperation.
Embodiment 2: the present embodiment the difference from embodiment 1 is that: referring to Fig. 2,16 inner wall of connecting cavity is equipped with to connecting cavity
The axial sealing ring 5 that inner wall and the mandril shaft place of being slidably matched are sealed, axial sealing ring 5 can avoid air pressure from gap location to
Outward leakage improves the efficiency conversion that atmospheric pressure is converted into spring force, reduces air pressure loss, guarantee clamping of the spring to cutter
Power.
Embodiment 3: the present embodiment the difference from embodiment 1 is that: referring to Fig. 3, the cell wall of sliding slot 132 is equipped with radially
Mating groove 121, corresponding position is equipped with the limited block 21 cooperate with mating groove 121, the cunning in mating groove 121 of limited block 21 on collet 2
It is dynamic to limit the position that collet moves radially, it avoids collet from skidding off, and make this fixture that there is certain scope of application, improves folder
Tight precision.
The above is only presently preferred embodiments of the present invention, not does limitation in any form to the present invention, it is all according to
According to any simple modification to the above embodiments in technical spirit of the invention, equivalent variations, guarantor of the invention is each fallen within
