Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Shown in referring to Fig.1, a kind of embodiment one of high-energy air inlet regulating device of the invention, air inlet adjustment of the invention Device is set on charge air flow path, adjusts the method for 12 size of air inlet by piston 20 to adjust air inflow, it is of the invention into Gas control device 1 includes shell 10, piston 20, screw rod 30 and feed screw nut 40, is hollow cavity 11, institute inside the shell 10 It states shell 10 and air inlet 12 and venthole 13 is respectively arranged with to side, gas is after the inflow hollow cavity 11 of air inlet 12 from out Stomata 13 flows out, and the piston 20 is arranged in the hollow cavity 11, the axis of the piston 20 and the air inlet 12 and The line of centres of venthole 13 is vertical, and piston 20 is enabled to block and decontrol air inlet 12 and venthole 13, the work simultaneously Plug 20 includes connecting rod 21 and dumbbell type the first cock body 22 and the second cock body 23 that are connected to 21 both ends of connecting rod, first plug The section of body 22 and the second cock body 23 is adapted with the section of the hollow cavity 11, and when not working, the second cock body 23 is by air inlet Hole 12 and venthole 13 block, and no gas passes through, the position of mobile piston 20, so that connecting rod 21 is located at air inlet 12 and outlet It is still the space of hollow cavity 11, air inlet 12 since 21 diameter of connecting rod is small, between connecting rod 21 and shell 10 between hole 13 The gas of inflow can be flowed out by hollow cavity 11 from venthole 13, and 20 axle center of piston is hollow, the feed screw nut 40 It is fixed on one end of the piston 20, is inserted into inside the piston 20 with 30 one end of screw rod of the feed screw nut 40 cooperation, separately Driving part is stretched out and be connected in one end from 20 hole of piston of the shell 10, in the present embodiment, shell 10,11 and of hollow cavity First, second cock body 23 is cube structure, on the one hand facilitates and shell 10 is fixed on charge air flow path, on the other hand, living Plug 20 will not opposite shell 10 rotate, therefore when driving part driving screw rod 30 rotates, since feed screw nut 40 and piston 20 are solid Surely it can not rotate, therefore feed screw nut 40 moves with piston 20 along 30 direction of screw rod, adjust the position of piston 20, and then adjust The size of air inlet 12 and venthole 13, in the present embodiment, the screw rod 30 is trapezoidal screw 30, can reduce manufacturing cost, And trapezoidal screw 30 have can be self-locking characteristic, can prevent piston 20 when gas shock from relatively rotating with screw rod 30, lead The change of 20 position of activation plug, to guarantee that piston 20 blocks air inlet 12 and when venthole 13, leakproofness it is good, described The both ends of piston 20, i.e. 22 end of the first cock body and 23 end of the second cock body are arranged with sealing ring 24, when connecting rod 21 is located at When between air inlet 12 and venthole 13, gas can only flow in the hollow cavity 11 around connecting rod 21, reduce gas From between 11 gap of the first, second cock body 23 and hollow cavity dissipate caused by lose, for guarantee piston 20 can block simultaneously and Decontrol air inlet 12 and venthole 13, the air inlet 12 is identical as 13 diameter of venthole, and between two cock bodys away from From the diameter not less than the air inlet 12 and venthole 13, the second cock body 23 is enabled to decontrol air inlet 12 and outlet completely Hole 13, air inflow can reach maximum value, and two cock bodys are additionally provided with chamfering to opposite, in piston when eliminating air inlet Impact when occurring the case where whirlpool on 20, while reducing air inlet to piston 20.
Referring to shown in Fig. 2, being two structural schematic diagram of the embodiment of the present invention, in the present embodiment, with one difference of embodiment It is, for convenience of piston 20 is made, the hollow cavity 11 and piston 20 are cylinder, while to prevent piston 20 and screw rod 40 transfer of nut, the position that the center of circle is deviateed in the end of the piston 20 are provided with guide rod 25, and 25 other end of guide rod is stretched The shell 10 out, due to the limitation of guide rod 25, piston 20 can only be moved along its axial direction, can not generate rotation, because This is rotated when driving part driving screw rod 30, and feed screw nut 40 moves with piston 20 along 30 direction of screw rod, adjustment piston 20 Position, and then the size of air inlet 12 and venthole 13 is adjusted, in the present embodiment, the axis and the air inlet of the piston 20 12 and venthole 13 the line of centres in the same plane it is smaller to the impact of piston 20 so that air flow method is uniform when air inlet, It is additionally provided with scale 26 on the guide rod 25, it can be as the reference for adjusting air inlet 12 size, when convenient for multiple air inlet Data record, in the present embodiment, 25 material of guide rod is 45# steel, and 10 material of shell is aluminium, guide rod 25 and aluminium The friction of shell 10 processed will not damage 25 high scale 26 of guide rod 25 and guide rod, extend the service life of whole device, this implementation In example, the driving part is handwheel 31, can manually adjust 12 size of air inlet, be provided with bearing in 20 hole of piston 32, enable screw rod 30 is smooth to rotate.
It is the application of air inlet regulating device of the invention on high-energy pneumatic vertical shock table referring to shown in Fig. 3, Air inlet regulating device 1 of the invention is fixed between air bubble 2 and impact test stage body 3, and when not working, turn-knob handwheel makes to lead It is predominantly located in hollow cavity to bar, the second cock body blocks air inlet and venthole, and when work, turn-knob handwheel makes the second plug Body portion blocks air inlet and venthole, the scale of record guide rod at this time, carries out impact test, log, then Continue turn-knob handwheel, decontrol air inlet and venthole, increase impact energy, records the scale of guide rod at this time, carry out impact examination It tests, log, then continues turn-knob handwheel until air inlet and venthole are decontroled completely and reach full admission amount, remember Record test result.The size of air inlet is adjusted using piston, realize it is accurate adjust high-energy pneumatic vertical shock table into The size of gas energy, structure is simple, easy to operate.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention Protection scope within.Protection scope of the present invention is subject to claims.
