Wheelbase Measuring Device and Wheelbase Measuring Method for Wheels on Two Sides of Complete Vehicle

Abstract

The invention aims to provide a wheel distance measuring device and a wheel distance measuring method for wheels on both sides of an entire vehicle, wherein the device is simple in structure, low in cost and convenient in operation. The wheel distance measuring device for wheels on both sides of the entire vehicle comprises two clamping and positioning mechanisms. Each clamping and positioning mechanism comprises a base provided with a sliding rail, and a sliding block is movably erected on the sliding rail. The sliding block is provided with a laser range finder and a movable clamping plate. One end of the slide rail is provided with a fixed clamping plate. The movable clamping plate and the fixed clamping plate are perpendicular to the sliding rail. The movable clamping plate is positioned between the laser range finder and the fixed clamping plate. The movable clamping plate and the fixed clamping plate are provided with through holes for the laser beam of the laser range finder to pass through. One surface of the fixed clamping plate, far away from the laser range finder, is provided with a target point used for the sighting of the laser range finder of the other clamping and positioning mechanism. According to the technical scheme of the invention, wheels are accurately positioned. Therefore, the measurement accuracy, the measurement consistency and the measurement efficiency are improved. The measurement error is effectively reduced. As a result, the excellent practicability is realized.

Description

technical field [0001] The invention relates to a device and a method for measuring wheel distance of wheels on both sides of a complete vehicle. Background technique [0002] In the current domestic vehicle appearance regulations and dimensions measurement, the method of measuring traces with basic tools such as tape measures is used to obtain the front and rear wheelbase dimensions of the vehicle, and the measurement efficiency, measurement accuracy and consistency are poor. [0003] The invention patent with the patent application number 200910091199.2 discloses a wheel set automatic measuring device, which installs a laser ranging sensor on a three-degree-of-freedom motion mechanism. Under the control of the measurement and control unit, the laser ranging sensor moves along the outer contour of the wheel. Relative movement, so that the distance between the laser ranging sensor and the wheel set surface and the orientation of the measuring line are kept within the range a...
