The utility model provides a tensile big deformation measurement device of high temperature superplasticity belongs to instrument technical field. It is great to measure superplasticity tensile sample shape variable error under the high temperature condition to prior art, and can't judge and take notes the production and development scheduling problem of constriction, high temperature furnace tension mechanism and deformation volume measuring mechanism, two camera record tensile deformation processes through being fixed in adjustable cloud bench during the measurement, through steps such as standard sample calibration back, it is horizontal big or small with fore -and -aft deformation to obtain the tensile sample through the measurement of image length change, also can rectify the result that obtains nearest truth to the error, through this production and development scheduling problem that can take notes the constriction. 本实用新型提供了种高温超塑性拉伸大变形测量装置，属于仪器技术领域。针对现有技术在高温条件下测量超塑性拉伸试样形变量误差较大、且无法判断并记录颈缩的产生和发展等问题，高温炉拉伸
