Abstract

The invention discloses a continuous variable force type torsional angle instrument. The instrument comprises a machine base, a first supporting arm and a second supporting arm, wherein the first supporting arm and the second supporting arm are arranged on the two sides of the upper end of the machine base, a to-be-tested piece round rod is arranged between the first supporting arm and the second supporting arm, a force arm is arranged at a tail end of the to-be-tested piece round rod, a spiral force increasing mechanism is arranged at a front end of the force arm, and one end of the round rod of the test piece is provided with an L-shaped support rod, the other end of the to-be-tested piece round rod is provided with a second L-shaped supporting rod, a tail end of the second L-shaped supporting rod is provided with a dial indicator, and a lower end of a measuring rod of the dial indicator is in contact with the first L-shaped supporting rod. The continuous variable force type torsion angle instrument is simple, practical and compact in structure, the load borne by the force arm is linearly changed through the use of the spiral reinforcement mechanism, the test error is reduced, and test accuracy is improved; and meanwhile, the device is light in weight, convenient to carry, low in gravity center, good in stability, firm in fixation and convenient to use.

Description

technical field [0001] The invention relates to the technical field of material mechanics devices, in particular to a continuously variable force torsion meter. Background technique [0002] The torsion test has been relatively mature in the field of material mechanics. There are various torsion testing machines and matching torsion angle meters in the domestic and foreign markets. At present, the teaching G-value test benches sold in the domestic market mainly include, SY .64-XH180, JC503-XH180, LL.24-3412, ZN-836-XH180, JY-2 and ZC4821. The experimental equipment commonly used in the shear modulus measurement experiment of basic physics experiments in colleges and universities is the G value determination test bench, which is mainly used in science and engineering colleges for the shear modulus G measurement experiment in material mechanics. A ready-made low-carbon steel sample is installed between the fixed support and the rotatable support on the test bench. The end of ...
