Abstract

The invention discloses a method and a device for measuring the diameter through a cantilever beam sensor and a coding lead screw. The device comprises a measurement host, an auxiliary positioning mechanism, a standard, a positioning block, a tested piece and a data acquisition-analysis-processing unit. The measurement host is composed of a base, a coding lead screw and a double-cantilever beam sensor. The coding lead screw is composed of a transmission lead screw and a three-state coder. The three-state coder is composed of a fluted disc and four pairs of cantilever beam sensors. The double-cantilever beam sensor is composed of a fixed cantilever beam sensor and a movable cantilever beam sensor. And system calibration, data analysis and error correction software is arranged in the data acquisition-analysis-processing unit. During measurement, the double-cantilever beam sensor clamps the tested piece and is matched with the coding lead screw to transmit a measurement signal to the dataacquisition-analysis-processing unit, and the data acquisition-analysis-processing unit gives a diameter value of the tested piece.

Description

technical field [0001] This design provides a method and device for measuring diameter with a cantilever beam sensor and a coding screw rod, which is used for the diameter measurement of circular cross-section samples in material mechanical performance tests and the diameter measurement of circular cross-section shaft parts in the industrial field. It belongs to sensors, mechanics Test technology and mechanical measurement technology field. Background technique [0002] Double cantilever beam diameter measuring instrument [1,2] It is a resistance strain measuring instrument with a resolution of less than 0.002 mm. It can measure the diameter of material tensile samples and other similar circular shaft parts with equal cross-section. The measurement accuracy is not affected by manual operation factors. It is suitable for Connect with data processor. However, the range of this instrument is generally below 2 mm, because the measurement range of the resistance strain sensor i...
