A swing-type three-dimensional detector for measuring static flatness

Abstract

The invention relates to the technical field of industrial production and system assembly, in particular to a swing-type three-dimensional detector for measuring static flatness; it includes an outer shell, a straight laser generator and an industrial camera, and the front and rear sides of the outer shell are provided with sealing covers , the lower surface of the outer shell is composed of a horizontal bottom plate and an inclined bottom plate, a projection rectangular hole is opened on the horizontal bottom plate, a shooting through hole is opened on the inclined bottom plate, and a camera mounting block is fixedly connected to the sealing cover above the shooting through hole, industrial The camera is fixedly arranged in the camera installation block; when the present invention detects the flatness of the plane of the parts, the parts are fixed, and the accuracy of the detection results is comparable to that of the existing three-dimensional visual inspection device for high-precision flatness detection. The difference is almost the same, but it effectively solves the problem that the existing irregular parts cannot keep perpendicular to the laser beam during the movement process, and its flatness detection method is simpler and more applicable.

Description

technical field [0001] The invention relates to the technical field of industrial production and system assembly, in particular to a swing-type three-dimensional detector for measuring static flatness. Background technique [0002] In the field of industrial production and system assembly, the flatness requirements for parts processing are particularly high, especially in the field of high-precision assembly and processing, the flatness error of the target plane must be high, and some even reach μ-level dimensional accuracy, that is, 0.001 mm accuracy requirements. At present, in the field of high-precision assembly and processing, most of the contact-type three-coordinate detectors are used to detect the flatness. However, the operation of the contact-type three-coordinate detector will introduce random errors every time, and it is also closely related to the detection operator. Therefore, a large number of non-contact detection methods are now developed, mainly due to the...

Problems solved by technology

Although the three-dimensional visual inspection device for high-precision flatness detection avoids the error introduced by human operation compared with the traditional contact three-coordinate detector, when the device detects the flatness of parts, it needs to be The detected parts are in a moving state, and the plane to be detected must be kept perpendicular to the laser beam at all times during the motion process, but when the plane of the irregular parts is detected, the parts cannot effectively guarantee the time and the laser beam during the motion process. Vertical, when the plane of the component to be detected is slightly inclined to the laser beam, the plane accuracy of its detection will have a large error

In addition, when the three-dimensional visual inspection device for high-precision flatness detection detects the verticality of the entire device when it is installed through the verticality detection rod, it is not only complicated in structure, but also unable to detect the verticality at all times after installation. During the operation and inspection of the device, if the installation is loose and the whole equipment is tilted and not adjusted in time, it will have a huge impact on the flatness inspection results
