Description
Technical field
This utility model relates to physical testing field, is specifically related to the quick of a kind of shock table lift cylinder
Gas handling system.
Background technology
The ability of the impact failure that acceleration shock machine bears during detecting Product transport or using,
Evaluate the impact resistance of product structure with this, and by test data, intensity of optimizing product structure, carry
High product quality, falls when the impact table top of shock testing machine rises to certain altitude and strikes on cushion pad,
Produce the shock pulse of semisinusoidal shape.Shock table of the prior art includes impacting main body, being positioned at impact
The top of main body impact table top, be arranged on impact main body on and drive connection impact table top lift cylinder with
And lock, with the piston rod of lift cylinder, the hydraulic pressure hydraulic pressure locking bar mechanism being connected, lift cylinder drives impact table top
To setting height, above-mentioned hydraulic lock linkage latching ram bar, make impact table top be positioned in setting height,
Being placed on by workpiece for measurement on impact table top, piston rod is unlocked by above-mentioned hydraulic lock linkage, and shock testing machine is worn
Dynamic workpiece for measurement does the movement of falling object, carries out impact test.
When carrying out impact experiment, the speed that impact table top falls to striking cushion pad is the biggest, and what it produced rushes
Shock pulse is the biggest, constantly increases the height of impact table top rising to obtain bigger shock pulse
Words, on the one hand the volume of equipment, the most excessive, and the stroke of the lift cylinder of impact table top must be very
Greatly, on the other hand, the decline resistance being subject to during the free-falling of impact table top also can be bigger, therefore
Existing shock table, typically while impact table top carries out the movement of falling object, increases auxiliary gas for it
Pressure, makes impact table top bigger in the speed of the more single freely falling body of speed falling to striking cushion pad, rises
Fall air cylinder driven impact table top to setting height, above-mentioned hydraulic lock linkage latching ram bar, make impact table top
Being positioned in setting height, be passed through air pressure in working chamber above, the working chamber being positioned at lower section discharges gas
Pressure, is placed on workpiece for measurement on impact table top, and piston rod is unlocked by above-mentioned hydraulic lock linkage, shock testing machine
Wear dynamic workpiece for measurement to decline under above-mentioned air pressure and freely falling body dual function, carry out impact test.Due to
The hydraulic lock clamp force of hydraulic lock linkage is limited, and the diameter of piston rod is the least, and its locking is the most reliable, lives
The diameter of stopper rod is the biggest, and its locking is the most unreliable, and therefore, the impact table top of existing shock table can only
Make small dimension, if the impact table top of shock table is made big specification, then lift cylinder
The diameter of piston rod also to strengthen accordingly, then, piston rod is by the deadweight of above-mentioned impact table top and assist gas pressure
Under dual function, hydraulic lock linkage cannot latching ram bar reliably.
