Basic Principles and Methods for Design Steps of Automotive Inspection Tools
The design steps of automobile inspection tools are as follows:
1. Design Modeling of Workpiece and Inspection-Automobile Inspection Tool
Firstly, according to the drawings or sample analysis work, the preliminary design plan of the calibration tool should be drawn up, the datum level, concave and convex situation, the cross section of the calibration tool and the positioning surface of the calibration tool should be determined, and the two-dimensional schematic diagram of the calibration tool should be drawn simply.
2. Design and Modeling of Section Template
The detection of the key workpiece profile is usually realized by the cross-section template. The cross-section template of the tool is divided into two types: rotary and insertion. When the span of the cross-section template exceeds 300 mm, in order to ensure the detection accuracy in the vertical direction, it is usually designed as insertion.
3. Positioning and Clamping of Workpiece-Automobile Inspection Tool
Correct and reasonable positioning of workpiece is the basis of accurate measurement. The positioning mode of body panels on the checking fixture is mainly accomplished by clamping positioning holes and chucks or clamping with permanent magnets.
4. Design of Baseplate Assembly
The upper surface of the inspection concrete is stretched a certain distance along the baseline direction, so that its minimum point is more than 150 mm thick, so as to ensure that the inspection concrete has enough strength. At the same time, the upper surface of the inspection concrete bottom, that is, the baseline surface of the base plate assembly, is located in the integral position of the body coordinate system as far as possible.
5. Hole Detection
Many important holes and flanges in body stamping parts need to be detected separately.
In addition to taking the above five points into account, the design of automobile checking tools should also follow the basic principles and methods of checking tool design.
1. Before designing the checking fixture, we must first determine the assembly position of this part in the whole automobile, the positioning method (including the selection and location of the positioning point), the fixing mode, and the relationship with the related parts around it.
2. The product is placed in the same way as it is placed in the whole car, that is, according to the loading position of the product, so that the product can reappear its actual state after the automobile assembly in the testing process, so that the measurement results can truly reflect the actual situation of the product assembly on the automobile.
3. Fixed product positioning point. Clamping point:
In the assembly of the whole vehicle, the X. Y. Z direction of the product is determined at three points of A. B. C. So far, the product has been fully positioned. The position tolerance of positioning datum should be less than 0.1 mm.
See here, you should probably understand the steps of automobile inspection tool design, just design involves the comprehensive consideration of the whole workpiece, so when choosing a automobile inspection tool factory to cooperate, we should consider the strength of the factory comprehensively, and make high-quality inspection tools is to ensure the high-efficiency output of the processing link.
