Embodiment
Below in conjunction with practical implementation the present invention is further specified:
A kind of lock transfers device forces testing device to comprise: support 1, bearing plate 2, adjuster bar 3, guide pole 4, butterfly spring 5 and force transducer 6;
Its medium-height trestle 1 utilizes the base of register pin and screw and experimental provision to fix;
The profile of guide pole 4 is " T " font, and butterfly spring 5 is sleeved on the guide pole 4, and the leading portion of guide pole 4 is sleeved in the guide pole pilot hole 10, and butterfly spring 5 quantity are two pairs, four of sums, and every pair of reverse symmetry is sleeved on the guide pole 4;
Four screw devices of force transducer 6 usefulness are fixed on the support 1, are positioned at the dead astern of guide pole 4, and closely contact with guide pole 4 rear ends;
Four threaded holes 7 are arranged on bearing plate 2; Be separately installed with set screw 8, threaded hole 7 communicates with adjuster bar pilot hole 9, can regulate the elasticity of bearing plate 2 and adjuster bar 3 through regulating four set screw 8; When bearing plate 2 out of plumb, also can regulate through set screw 8.
Transfer in the stressed process of the test of device at lock, support 1 is fixed with the testing table table top.Lock transfers device to be connected with bearing plate 2 through coupling arrangement.When lock transferred device stressed, power at first acted on the bearing plate 2 through the effect of coupling arrangement; This moment 2 of bearing plates stressed be pressure, pressure passes to butterfly spring 5 by bearing plate 2, passes to guide pole 4 by butterfly spring 5; Pass to force transducer 6 by guide pole 4, can measure stressed size.Because the gap between in the middle part of on bearing plate 2 and the adjuster bar 3 equals the deflection less than butterfly spring 5, when stressed maximum distortion range less than butterfly spring 5, can not cause damage to force transducer 6.And when stressed when surpassing the maximum distortion range of butterfly spring 5, unnecessary power will act on the middle part on the adjuster bar 3, be delivered on the support 1, avoid the damage of force transducer 6.
