A precision testing device for frame measurement

Abstract

This utility model discloses a precision testing device for frame measurement, belonging to the field of automated testing technology. Its key technical features include a testing platform with a three-dimensional measuring instrument fixedly connected to its top. A unidirectional positioning mechanism is movably connected to the top of the testing platform, and a unidirectional adjustment component is movably connected to the inner side of the unidirectional positioning mechanism. By setting a circular positioning groove at the center of the three-dimensional measuring instrument's processing platform and using a servo motor to drive the guide plate to rotate, the extrusion column drives the linkage slide plate and positioning soft column to synchronously push the frame from multiple directions to the vicinity of the center of the top plate, which is near the coordinate origin. Furthermore, the positioning soft column can deform to fit the frame surface. This solves the problem that traditional positioning only positions the small frame in the placement area, affecting the accuracy, efficiency, and stability of the three-dimensional measurement. It achieves precise positioning of the frame to the vicinity of the coordinate origin, ensuring the accuracy, efficiency, and stability of the testing process.
