Image measuring instrument

Abstract

The invention discloses an image measuring instrument which comprises a lens mount, wherein the lens mount comprises a first connection plate, a second connection plate, a first lens clip and a second lens clip, the upper end of the second connection plate is hinged with the outer part of the first connection plate, the two symmetrical ball screws are fixed at the lower end of the first connection plate, the extension ends of the two ball screws are connected with the screwed holes of the inner side of the second connection plate, and the first lens clip and the second lens clip are respectively fixed at the outer parts of the two ends of the second connection plate through oval holes and bolts which are arranged on the first and second lens clips. The image measuring instrument of the invention has a simple structure, and the verticality between the center of the lens of a microscope and a workbench can be accurately adjusted during the installation and measurement processes of the instrument, so the measurement error is reduced.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, and in particular relates to an image measuring instrument, which is widely used in industries such as machinery, instruments, clocks and watches, and light industry. Background technique [0002] Image measuring instrument, also known as precision image surveying instrument, overcomes the shortcomings of traditional projectors and is a new type of high-precision, high-tech measuring instrument integrating optical, mechanical, electrical, and computer image technologies. The optical microscope performs high-magnification optical magnification imaging on the object to be measured. After the enlarged object image is sent to the computer through the CCD camera system, it can efficiently detect the contour and surface shape, size, angle and position of various complex workpieces, especially precision Microscopic inspection and quality control of parts. The measurement data can be direc...

Problems solved by technology

At the same time, the fixing method of the microscope is also non-adjustable. Therefore, whether the center of the microscope lens is perpendicular to the workbench can only be guaranteed by mechanical processing. However, in the process of machining, installation and measurement, the center of the lens and the workbench It is impossible for the verticality to remain unchanged, which will easily lead to errors in measurement results
