The invention have the benefit that a kind of self-locking air spring compression stress that the present invention provides and tired strong
Degree integration special inspecting equipment, under original state, the piston rod of workpiece is fully extended, and now operation is opened
Pass makes workpiece be in self-locking state, during work, is first placed on workpiece support slide block by workpiece to be detected,
Specifically, workpiece piston rod senses towards the outfan of solution lock cylinder, the tail end of workpiece cylinder barrel towards power
Device；After workpiece has been placed, start motor, drive pushing slide block to advance, directly by ball screw
Contact to force transducer with the cylinder barrel of workpiece；And then in solving lock cylinder, it is filled with compressed gas, by solving
The operation switch of the outfan pressing piston rod end of lock cylinder, makes workpiece unlock；After unblock, again open
Dynamic motor, drives pushing slide block to move on 10mm, now shows that the compression travel of piston rod is
10mm, then makes motor invert, and drives pushing slide block to retreat 5mm, and the compression travel making piston rod is
5mm, the force value obtained now by force transducer is then for the F1 value (i.e. compressing force value) of workpiece；F1 value is surveyed
After having tried, repeatedly moved back and forth by step motor drive pushing slide block, make piston rod synchronize to make big row
Journey moves back and forth, it is achieved the test to workpiece fatigue strength.
Compared with existing manual mode of operation, the present invention is by arranging motor and ball screw so that
Being prone to grasp the stroke of piston rod during work, structure is arranged simply, operates more convenient, is effectively increased
The precision measured, makes controllability of the present invention higher, and, owing to using mechanical type processing, add actual
During work, each workman can at least control two detection equipment of the present invention, not only reduces
The labor intensity of workman, improves work efficiency, the most effectively saves artificial input cost.
