Embodiment Construction

[0018] Such as figure 1 with figure 2 As shown, the present invention consists of a linear array CCD measuring instrument for measuring the height of the longitudinal rib, a photoelectric aiming optical projector for measuring the inner diameter and the height of the transverse rib, a computer control system, a bracket and a guide part 9. Among them, the photoelectric aiming optical projector is composed of a light source 1, a measuring head 7, an imaging system 2, and a photoelectric aiming device 3. The parallel light generated by the light source illuminates the measured piece inside the measuring head, and its projection is amplified by the imaging system to clearly The measurable image is imaged on the projection screen, then targeted and measured by the photoelectric aiming device, and the measured data is input into the computer for processing. The linear array CCD measuring instrument part is composed of a CCD light source 5, a measuring head 7 (8 is the measuring in...

Abstract

The on-line three screw thread steel parameter measuring system features that the measuring system consists of linear CCD array measuring instrument for measuring longitudinal rib height, photoelectronic collimating optical projecting instrument for measuring inner diameter and transverse rib height, and computerized control system. The linear CCD array measuring instrument and the photoelectronic collimating optical projecting instrument are two independent measuring systems to measure screw thread steel in two perpendicular directions through sharing one common measuring head. The measuring signals of two directions are fed to the computerized control system simultaneously, and the computerized control system completes data treatment before outputting measurement results.

Description

Technical field [0001] The invention relates to a three-parameter on-line measuring system for threaded steel. technical background [0002] At present, the rebar parameter measuring instruments introduced in various documents or materials basically use linear array or area array CCD for measurement.
