Detailed description of the invention
As shown in Figure 1: gas dust-proof undamped regracting formula elastic locating mechanism, including location key seat 1, it is characterized in that: in location key seat 1, have through hole, be slidably connected in through hole alignment pin 2, in the bottom of location key seat 1, spring base 3 is set, the lower end of spring 5 is positioned at spring base 3, and the upper end of spring 5 contacts with alignment pin 2.
Arrange the cylindrical body downwardly extended in the bottom of location key seat 1, described spring base 3 is positioned at the bottom of described cylindrical body；The lower end of alignment pin 2 has counterbore, and spring 5 upper end is positioned at described counterbore, and alignment pin 2 can do rectilinear motion with spring 5.
The hole wall top of through hole is provided with annular groove 9；The side of described location key seat 1 is provided with built-in gas circuit 10, and one end of built-in gas circuit 10 connects with annular groove 9；Be provided with high pressure admission mouth 11 in the bottom of described location key seat 1, the other end of built-in gas circuit 10 connects with high pressure admission mouth 11.
Described location key seat 1 side is provided with slide opening 8, and the axis of described slide opening 8 is parallel with the axis of through hole.
Described built-in gas circuit 10 includes the horizontal gas circuit that is interconnected and vertical gas circuit, described vertical gas circuit is parallel with through hole, the outer end of vertical gas circuit connects high pressure admission mouth 11, the inner of vertical gas circuit connects with horizontal gas circuit, the outer end of horizontal gas circuit is provided with plug 4, and the inner of horizontal gas circuit connects with annular groove 9.
Described high pressure admission mouth 11 is provided with sealing ring 6.The head of described location key seat 1 is additionally arranged chamfering.Being provided with limit base 7 in described spring base 3, arrange limited impression in limit base 7, the lower end of described spring 5 is positioned at limited impression.
Gas of the present invention dust-proof undamped regracting formula elastic locating mechanism is according to actually used situation, in the Zhang Xinlong patent No.: gained after making improvement on 200810124443 elastic positioning pin without gas damp bases.Present invention eliminates the dust ring on former patent location key seat 1.The dust-tight manner that dust ring adopts is that mechanical type is dust-proof, and its mechanical damping is relatively larger, when the workpiece that alignment quality is lighter, stuck phenomenon is there will be owing to spring force is little, alignment pin 2 bullet is not gone out, and the service life of spring 5 is had a direct impact by it, is not easy to adjust elastic positioning pin spring force simultaneously.
The structure of location key seat 1 is improved by the present invention, it is additionally arranged the chamfering of head, decreases the chance that dust, iron filings etc. enter, in location key seat 1, offer the through hole run through, the upper end hole wall upper end of through hole is provided with annular groove 9, and communicate high pressure admission mouth 11 with annular groove 9.
The operation principle of the present invention: gases at high pressure enter annular groove 9 from the sealing ring 6 on location key seat 1 by built-in gas circuit 10, plug 4 closes another outlet of built-in gas circuit 10, and high pressure gas knows from experience one higher-pressure region of formation in the annular groove 9 offered in location key seat 1.There is up and down motion in location key seat 1 and alignment pin 2, therefore there is fit clearance, high pressure gas cognition sprays up and down along gap, the gas of ejection is by the hole on the limit base 7 on spring base 3 and atmosphere, the gas upwards the sprayed top end of annular groove 9 owing to offering in location key seat 1 downwards, and gas major part sprays from upper end, dust, iron powder, cutting fluid etc. can not enter in fit clearance, thus reaching dust-proof effect.Gases at high pressure also can form annular air film in fit clearance, reduces the frictional force between location key seat 1 and alignment pin 2 up and down motion, thus the abrasion decreased between pin and shank, improves the life-span of alignment pin.
It is dust-proof that the present invention not only achieves gas, also makes alignment pin shank and key seat realize mechanical damped motion, and the service life of the motility and spring that improve elastic positioning pin motion improves machining accuracy and production efficiency, thus reducing operating cost.
