Full-automatic chassis electronic measuring instrument for vehicle

Abstract

The invention discloses a full-automatic chassis electronic measuring instrument for a vehicle. The measuring instrument comprises a multi-joint mechanical arm. A probe and a positioning device are mounted at the moving end of the mechanical arm; a displacement compensation mechanism used for controlling the mechanical arm to move and rotate in a large range is arranged under the fixed end of themechanical arm. A camera device 4 is installed on the displacement compensation mechanism, a movable workbench is arranged below the displacement compensation mechanism, a control terminal is arrangedin the movable workbench, and the control terminal is electrically connected with the mechanical arm, the positioning device, the displacement compensation mechanism and the camera device. The measuring instrument can conveniently, flexibly and automatically detect the automobile chassis to be repaired, reduce the workload of workers, determine the repair position through twice accurate positioning, expand the detection range of the mechanical arm through the displacement compensation mechanism, reduce positioning errors caused by movement of the movable working platform, and improve the positioning precision.

Description

technical field [0001] The invention belongs to the technical field of electronic measurement of automobile chassis, and in particular relates to an electronic measurement instrument for a fully automatic vehicle chassis. Background technique [0002] The chassis of the car is the benchmark of the whole car. After an accident and deformation, it is first necessary to obtain the data of the chassis for correction. However, traditional electronic measuring instruments for automobile chassis have high requirements for technicians, and the operation steps are cumbersome, labor-intensive, low-efficiency, and measurement data depends on proficiency, resulting in high technical thresholds for chassis measurement, high costs, and difficult quality assurance. In recent years, the wide application of industrial robots has received widespread attention, especially in vehicle assembly, but rarely in the field of vehicle maintenance. If robots are used to develop chassis measurement equ...

AI Technical Summary

Problems solved by technology

How to reduce the measurement error caused by the accumulation of fit clearance through mechanism optimization design is the key to the design. At present, there is no automatic equipment for automobile chassis data measurement. Therefore, it is very necessary and meaningful to develop an automatic chassis measuring instrument.
