Manual image measuring instrument

Abstract

Through adjusting gear, CCD camera and zoom lens are connected; and through lens clamp, CCD camera and zoom lens are fixed on fixation adjustment device for camera and microscope. Through bolt, the camera and microscope is connected to the connection base plate in z-axis. The connection base plate in z-axis is fixed on a nut in z-axis. Through screw thread, transmission shaft in z-axis is connected to the nut in z-axis. Through bearing seats, the fixed transmission shaft is connected to horizontal transmission shaft through helical beval gear. Rotating handwheel installed on the horizontal transmission shaft makes transmission shaft in z-axis rotate so that nut and the connection base plate are moved along guide rail in z direction up and down.

Description

Technical field: [0001] The invention relates to the technical field of measuring instruments, in particular to an easily adjustable high-precision manual image measuring instrument. Background technique: [0002] With the continuous improvement of the level of industrial processing and manufacturing, the size of the products to be tested is constantly decreasing, so new requirements are put forward for the detection methods. The previous detection methods such as manual detection can no longer meet the new detection requirements. Computer vision inspection technology has been widely used in industrial inspection because of its good flexibility, non-contact, fast and efficient characteristics. In computer vision inspection, the adjustment and calibration of hardware is very important, among which the adjustment of CCD and lens is one of the keys. Before measurement, it is necessary to ensure that the center of CCD and the center of the lens are on the same axis, so this adju...

AI Technical Summary

Problems solved by technology

However, at present, the connection between the CCD and the lens of the image measuring machine is connected by c-mount, and the center of the CCD and the center of the lens cannot be adjusted; Whether it is perpendicular to the workbench is completely guaranteed by machining, and cannot be adjusted. It is difficult to guarantee the perpendicularity of the lens and the workbench

Due to the above two reasons, it is difficult to ensure the accuracy of the measurement during the measurement process

At the same time, in the prior art, the movement of the Z axis is adjusted by the handle installed on the Z axis, so it is very inconvenient to adjust during the measurement process. In addition, there is no counterweight device in the structure of the prior art, so the resistance of the adjustment Larger; there is no adjustment device between the base and the support base and the bottom of the support base, which also has a great impact on the levelness of the workbench
