A tensile testing apparatus for thermoplastic materials

Abstract

The utility model discloses a tensile testing technical field's thermoplastic material tensile detection device, including, shell, clamping component, temperature control assembly, motor and screw rod, be provided with baffle in the shell, divide the shell into upper chamber and lower chamber, clamping component sets up in the upper chamber for clamping thermoplastic material sample, motor sets up in the lower chamber for driving the rotation of screw rod, drives the movement of a part in clamping component, temperature control assembly is used for adjusting and maintaining the constant temperature inside the upper chamber, the utility model discloses adopt upper and lower clamping main body cooperation trapezoidal groove structure, and combine the linkage clamping mechanism of rotatable connecting plate and clamping block, through telescopic link control clamping block along the sliding of inclined plane, realize the adaptive clamping of sample, make clamping block have the same clamping force, through the replacement into the clamping block of same size with sample size, can effectively prevent the sample clamping slip or clamping break problem caused by uneven clamping force, improved the reliability and test repeatability of clamping.
