Description

Bone pull and torsion test device
Technical field
The utility model provides a kind of novel device of bone pull and torsion test, belongs to biomechanics testing equipment field.
Background technology
In biomechanics testing machine industry, skeletal mechanics testing equipments such as biomechanical property testing machine can only carry out the test method that individual event stretches, compresses or reverse usually, and in modern medicine study, stress when more needing highly to imitate the bone real motion, this just needs and can carry out bone simultaneously and draw and turn round or press the experimental facilities of turning round the composite testing function, does not satisfy the test unit of this requirement at present.
Summary of the invention
The utility model provides a kind of bone pull and torsion test device, can not carry out bone at present simultaneously and draws and turn round or press the problem of turning round composite testing to solve.
The technical scheme that the utility model is taked is: fixedly connected with load sensor in the upper end of going up the power bar of bindiny mechanism, fixedly connected with top shoe in the bottom, top shoe is fixedlyed connected with linear bearing one, linear bearing one is slidingly connected with guidepost, guidepost is fixedlyed connected with upper bracket, and upper bracket is fixedlyed connected with moving beam, and last anchor clamps are fixedlyed connected by pin with last bindiny mechanism, lower clamp and torque sensor upper end are fixedly linked, and fixedly connected with reducing gear in the torque sensor lower end; The base plate of reducing gear is connected with the stationary table of testing machine, bearing seat is fixedlyed connected with base plate, big belt wheel is fixedlyed connected with radial ball bearing one, lower carriage, following guidepost is fixedlyed connected with big belt wheel, the downslide kinetoplast is fixedlyed connected with linear bearing two, linear bearing two is slidingly connected with following guidepost, fixedly connected with torque sensor in downslide kinetoplast upper end, axle passes through thrust bearing, radial ball bearing two is rotationally connected with bearing seat, servomotor is fixedlyed connected with planetary reducer, small pulley is fixedlyed connected with the output terminal of planetary reducer, big belt wheel, small pulley connects by cog belt.
Advantage of the present utility model is novel structure, can guarantee that torque sensor does not bear pressure, because thrust bearing has been installed, significantly reduced the moment of friction of reversing that produces when applying axial push-pull power, guaranteed the precision height of test, can carry out bone simultaneously draws and turns round or press and turn round composite testing, the stress when highly imitating the bone real motion.
