Triaxial rotating work platform for optical element detection

Abstract

The invention discloses a triaxial rotating work platform for optical element detection and relates to an optical element detection tool. The invention provides the triaxial rotating work platform for the optical element detection, which can rotate triaxially and cooperate with a three coordinate measuring machine to realize the accurate measurement of an optical element form surface. The triaxial rotating work platform is provided with a worktable, a base, a worktable inclination angle regulation mechanism and a worktable fastening mechanism, wherein the lower surface of the worktable is arranged on a groove on the base; an oil groove is formed in the groove on the base; the worktable inclination angle regulation mechanism is provided with six positioning bolts; the worktable fastening mechanism is provided with a connecting rod, a connecting rod spring, transverse fastening screws, longitudinal fastening screws, a fastening wedge block and a baffle plate; the connecting rod passes through a center hole of the worktable; the lower end of the connecting rod is connected to the base by a spring, and the upper end of the connecting rod is provided with the fastening wedge block; two transverse fastening screws are arranged at side ends of the fastening wedge block; the longitudinal fastening screws are screwed into screw holes of the top part of the fastening wedge block by passing through the baffle plate; and the worktable can be locked by rotating the longitudinal fastening screws.

Description

technical field [0001] The invention relates to an optical element inspection tool, in particular to a three-axis rotating work platform for optical element inspection. Background technique [0002] As an important detection tool, three-coordinate measuring machines are widely used in machinery, automobiles, aviation, military and other industries. The detection objects can include boxes, racks, gears, cams, worm gears, worms, blades, curves, and curved surfaces. , various tool prototypes, machines and other small and medium-sized accessories, can carry out precise detection of the size, shape and shape tolerance of the workpiece, so as to complete the tasks of part detection, shape measurement, process control and so on. Its structure is provided with guide mechanism, length measuring element and digital display device in three mutually perpendicular directions, and has a workbench where the workpiece can be placed. The measuring probe can be moved to the measured point man...

AI Technical Summary

Problems solved by technology

Usually, the measuring probe of the three-coordinate measuring machine is fixed on the mechanism of the moving guide rail, and the detection direction cannot be adjusted. For optical components with different shapes, it is easy to have detection blind spots, and it is difficult to complete the complete detection of all shapes and surfaces of the workpiece (for example, the publication number is CN201348477 utility model patent "three-coordinate measuring machine")

The general method is to measure the blind area by changing the detection direction of the measuring probe, but re-clamping the measuring probe reduces the detection accuracy
