Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of twist mechanism that is used for testing torsional fatigue of wire, fixed clamp device conveniently moving can be adjusted the distance of rotating between clamper and the fixed clamp device easily according to the metal wire rod diameter, and adjusts the precision height.
The utility model has adopted following technical scheme: the twist mechanism that is used for testing torsional fatigue of wire, it mainly is made up of frame, rotation clamper, fixed clamp device and motor, described motor output shaft connects with the rotation clamper, described rotation clamper and fixed clamp device are installed on the same horizontal line of frame, two clamper parallel axes, rectification that distance between the two is adjustable becomes.
Described rotation clamper is fixedly mounted on the frame, and described fixed clamp device is slidably adjusted the position.Described frame is provided with vernier caliper, and described fixed clamp device is fixed on the vernier measuring jaw of slide calliper rule and can moves with measuring jaw, and rotation clamper axis aligns with the zero graduation line of described vernier caliper.Described fixed clamp device is supported by bearing, be provided with the axially extending bore line that is used to insert wire rod in the bobbin, bobbin is made up of locating sleeve, lifting axe, bearing holder (housing, cover), bearing and plug wire axle, described lifting axe, magnetic patch, plug wire axle are arranged in locating sleeve successively, the end thread of described bearing holder (housing, cover) and locating sleeve is connected, described plug wire axle is supported by bearing, and the plug wire axle is provided with the axially extending bore that is used to insert wire rod.Also be provided with steady line seat on the described frame, described steady line seat is provided with the groove bracket facing to a side of wire rod, and the process groove was by the bracket supplemental support when wire rod reversed.
The utlity model has following beneficial effect: fixed clamp device and rotation clamper parallel axes, when the distance between two axial lines requires to change according to gauge or diameter of wire to be measured is different, as long as the vernier measuring jaw of moving cursor slide calliper rule, move easy to adjust, and degree of regulation improves greatly, can reach 0.02mm.During test wire rod torsional fatigue test, after metal wire rod sheared predetermined length and make sample by diameter, metal wire rod one end is fixed on the rotation clamper, the other end is by the clamping of fixed clamp device, wire rod becomes U-shaped from slew, form precharge on metal wire rod, sample until sample fracture, can draw the sample fatigue limit around the rotation of self axis.
