With the development of economy, special vehicles more and more applied to logistics, with the rapid development of highways, the vehicle faster and faster, because the prices of special vehicles are not allowed to locate the problem caused more prominent. Special vehicle frame positioned right questions to the time that must be addressed.Articles by laser ranging technology for special vehicle location detection of the frame, laser ranging technology is the leading a rangefinder as well as the domain, and laser possesses excellent monochromatic, directional sex, high brightness, strong energy density and super specular power characteristics,such as laser technology will quickly applied to all kinds of measurement. The laser rangefinder by electro magnetic chuch convenient installation to axles,electro-magnetic chuck is a kind of electromagnetic fixture, it is used to fix the processed components by the suction produced by Chuck body which are through the magnetic coil.Paper based on laser range finder and the principle of electromagnetic sucker design to solve the current frame positioning system to locate the production of special vehicles are not allowed to question. In order to achieve simple visual effect, chose SolidWorks and CAD software carries on the design. To SolidWorks as a platform for a dedicated parts of the vehicle frame positioning device modeling, virtual assembly, exploded view and so on.This paper analyzes the laser rangefinder and electro magnetic chuch principle, designs the special vehicles frame positioning device,and the framework of frame positioning device using SolidWorks software component modeling, assembling, explosion view design. In the special vehicles frame positioning device parts design, the main design electro magnetic chuch, ruler, etc, used by operating mainly has tensile, mirror, spin, scan, etc.Through various circumstances frame positioning device error analysis shows that by using laser range finder technology localization method is simple, to ensure accuracy. |
