The present invention realizes with following technical scheme: a kind of single-cylinder bolt hydraulic cylinder pin inserting-pulling device testing stand, comprise test-bed, described test-bed comprises manual raceway, cylinder pin biaxial loadings device, arm pin charger, cylinder head position regulator and balancer support;
Described manual raceway comprises the track that its upper end of framework is horizontally installed with many carrying roller compositions, track is placed the cylinder head position regulator that can move left and right in orbit;
Described cylinder pin biaxial loadings device comprises framework, guide rail, load cylinder, positional cylinder, lift cylinder and positioning sleeve, is respectively provided with positional cylinder and positioning sleeve at the front and back facade of framework, realizes the location to cylinder pin, fixes when stretching out; Be separately installed with load cylinder in the left and right side of framework, rise under the push-and-pull of lift cylinder or decline, biaxial loadings is carried out to cylinder head;
Described arm pin charger is arranged in framework, realizes stressed effect when arm pin cylinder loads;
Described balancer support installing is on the top of framework; For pipeline is suspended in the air.
Its motion principle:
A, cylinder pin external load: by front and back load cylinder, promote subjects and move by provisioning request, make to clash into inside cylinder pin and positioning sleeve, and extrude certain hour, realizes suffered external impacts situation when cylinder pin works;
B, cylinder pin are flexible: with snap joint, connection control system, realize it and stretch;
C, arm pin stretch: when in addition arm pin load, with snap joint connected system, realize it and stretch.
Beneficial effect of the present invention is: can carry out product actual effect checking (as cylinder arm pin telescopicing performance, sealing property etc.), provides test data and key position to be out of shape improvement that is stressed and cylinder head global design.And data and test can be provided to support for studying the impact of various fit clearance, the relation checking of spring rate and oil pressure, synchronous, the unbalance loading of bolt device and life-span etc.Thus while improving product total quality level, reduce R&D costs, improve Design hierarchy and efficiency, solve feedback lag issues.Compact conformation is attractive in appearance, easy for installation, and simulate effect is good, instant effect.
