The methods and steps of small car inspection tools

Date of release:2018-06-07 Author: Click:

 

1, the body small stamping parts inspection mainly consists of the floor assembly, inspection, cross section, main and vice pin and clamping device group. The main elements of the detection are the shape of the workpiece, including the contour of the workpiece and the shape of the surface, etc., with holes, flanges and other characteristics. In the design of a small car inspection tool, the size datum is generally placed in the body coordinate system. In the direction of X, Y, and Z, each 100mm is marked each other, and the reference frame of the base and the reference hole on the floor is set up.


2. Most of the body stamping parts have spatial surface and more local features, which have the characteristics of non axisymmetric, poor rigidity and so on. Therefore, it is difficult to locate, support and clamp. Now most of the body stamping parts are checked by the numerical control machine tool according to the number mode and the predetermined processing program to complete all the required surface and hole position automatically. The concrete material of the small car inspection is mostly epoxy resin. After the inspection is completed, the position and size of the bottom plate assembly are determined according to the vehicle inspection tool body. Method, and cross section template is set up in key section to be detected.


General steps for the design of vehicle inspection tools:


First of all, we should analyze the workpiece with reference to the parts drawing, initially draw up the design scheme of the inspection tool, determine the datum surface, the concave and convex condition, the detection section, the location surface and so on, and draw the two-dimensional sketch map simply.


In the design of checking fixture, it is the key to check the specific design modeling, which directly affects the accuracy of checking the quality of the workpiece. Due to the characteristics of free surface, the reverse engineering is a general method of modeling. The reverse is based on the existing workpiece or physical prototype, using the laser scanner to collect data, and through the process of data processing and 3D reconstruction, the method of building a prototype model with specific shape structure is constructed by the method of data processing and 3D reconstruction. We use the laser scanner to scan the surface of the standard workpiece, collect the feature information of the workpiece surface based on the point cloud, convert the point coordinates to the body coordinates, and use the surfacer software to deal with the point information, get the feature curve of the surface surface of the workpiece, and generate the final free surface model. At the same time, the point cloud can be passed through the point cloud. The maximum and minimum distance to the surface is used to detect the generated prototype model. It should be noted that the model at this time is a slice model without thickness. It is necessary to distinguish the model into the inner or outer surface of the workpiece according to the scanned surface of the scanner, which is particularly important for the specific design.
