Description

Technical Field

[0001] The utility model relates to the technical field of image measuring instruments, in particular to an image measuring instrument with an automatic anti-collision function. Background Art

[0002] The image measuring instrument is based on CCD digital images and relies on the powerful software capabilities of computer screen measurement technology and spatial geometry operations. After installing special control and graphic measurement software, the computer becomes a measurement brain with a software soul and is the main core of the entire device. It can quickly read the displacement value of the optical ruler, and instantly obtain the desired results through software module operations based on spatial geometry, and generate graphics on the screen for operators to compare images and images, so as to intuitively distinguish possible deviations in the measurement results. There are many types of image measuring instruments, and automatic image measuring instruments are one of them. However, the existing automatic image measuring instruments have the following disadvantages: the base and the measuring instrument body are susceptible to external collisions, and the interior of the base and the measuring instrument contain a large number of precision components, so that when it is collided, it is easy to cause damage to the precision components inside the equipment due to the large impact force of the collision, and then cause unnecessary losses, and the practicality is poor.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN214036687U in the prior art discloses an anti-collision automatic image measuring instrument, including a base, a bearing seat, a mounting frame, a main body, a movable seat structure, universal wheels, a first anti-collision structure and a second anti-collision structure, wherein the bearing seat is installed at the upper end surface of the base, the mounting frame is fixedly installed at the upper end surface of the bearing seat, the main body is movably installed at the mounting frame, the movable seat structure is installed at the bottom of the base close to its four inner corners, four universal wheels are provided, all of the four universal wheels are provided with a brake mechanism, and the four universal wheels are fixedly installed at the bottom of the movable seat structure, the first anti-collision structure is installed on both sides and the front of the base, and the second anti-collision structure is installed on both sides and the front of the main body.

[0004] Although the above-mentioned prior art solution can prevent the main body of the equipment from being damaged by impact, when performing measurement, it is necessary to place the object to be measured at the measuring position of the image measuring instrument, and then adjust the image measuring instrument to ensure that the image measuring instrument is focused on the object to be measured. During the measurement process, it is easy for the measuring lens of the measuring instrument to collide with an obstacle due to incorrect operation, and the lens is very fragile, so the lens is easily damaged during the collision, which in turn causes the device to be unable to continue to be used, affecting work efficiency.
