Abstract

The invention relates to the technical field of automatic detection equipment of tolerance and in particular relates to a framework type rack planeness detection device and method. The framework type rack planeness detection device comprises a detection platform, a hydraulic elevator and a self-walking platform, wherein the detection platform is provided with a laser distance measuring assembly for detecting the planeness of a detected rack; the hydraulic elevator is correspondingly and coaxially mounted under the detection platform and is used for driving the detected rack to move along the vertical direction; and the self-walking platform and the detection platform are coaxially arranged, and the self-walking platform can drive the detected rack to move along the horizontal direction. Based on the framework type rack planeness detection device above, the invention provides a framework type rack planeness detection method. The framework type rack planeness detection device and method, provided by the invention, have the characteristics of high automation degree, high measurement precision, convenience for operation and the like, and can be adaptive to a production line production environment, so that the labor intensity of users is effectively alleviated and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tolerance automatic detection equipment, in particular to a frame-type rack flatness detection device and a detection method. Background technique [0002] The flatness of the frame rack is related to the assembly quality of the vehicle, and plays a very important role in the reliability and service life of the vehicle. At present, the measurement methods of this kind of frame plane mainly include the meter measurement method, the liquid level method, and the beam plane method. In addition to the above methods, there are also instruments such as plane interferometers, level meters, and autocollimators to measure the flatness of large planes. error. These methods or instruments have a low degree of automation during measurement, and the operation is cumbersome, so they are not suitable for the assembly line production environment. [0003] The evaluation methods of flatness error include three far point ...
