Because of its unique characteristics, automobile inspection tools of automobile manufacturers are mainly used in the field of automobile engine. The development of automobile inspection tools by automobile manufacturers is widely used in production considering practicality, effectiveness, timeliness and economy. With the development of the automobile industry, especially the transfer of automobile parts processing to China, the market space of automobile inspection fixture manufacturers is expected to be further improved. Automobile inspection fixture manufacturers face a broader market prospect, and innovation + practical is the goal. Below follows the automobile inspection tool manufacturer to understand how the automobile inspection tool manufacturer's design concept.
1. Specific design modeling of workpiece and inspection -- automobile inspection tools
First of all, the workpiece should be analyzed by referring to the drawings of parts, and the design scheme of the inspection tool should be preliminarily drawn to determine the reference level, concave and convex condition, inspection section, positioning surface, etc. of the automobile inspection tool manufacturer, and simply draw its two-dimensional diagram. In the design of automobile inspection fixture, the design and modeling of inspection fixture is the key, which directly affects the quality of inspection workpiece.
Car fixture manufacturers of auto detection of free surface of workpiece, generally keep inspection within the concrete surface and the workpiece surface 3 or 5 mm constant clearance, numerical control machine tool can according to the design of profile da reached the requirements of higher accuracy, when the actual detection by fixture type surface with the special measuring tool of reciprocating movement can measure the work piece surface deviation.
2. Design and modeling of section templates
The detection of the key shape of the workpiece is generally realized through the section sample. The section sample of the automobile inspection tool manufacturer is divided into two types: rotary type and insert type. When the span of the section sample exceeds 300mm, in order to ensure the vertical detection accuracy, it is usually designed as insert type. The specific surface of automobile inspection by automobile inspection tool manufacturer is the inner surface of the workpiece. The section sample is across the outer surface of the workpiece to detect the outer surface of the key section. Generally, the working surface is 2-3mm away from the outer surface of the workpiece.
3. Positioning and clamping of workpieces -- automobile inspection tools
Correct and reasonable positioning of workpiece is the basis of accurate measurement. With the wide application of automobile inspection tools from automobile manufacturers in automobile body manufacturing, lever movable chuck and * magnet are available in a series of products, and movable chuck is also equipped with brackets or brackets of different types and sizes. Most of the body covers have two positioning holes, the main positioning pin is generally a cylindrical pin (round hole) or a diamond pin (waist hole), to limit the degree of freedom in both directions. The auxiliary locating pin is a taper pin or diamond plug pin, which is used to limit the degree of freedom in Z.X.Y.Z four directions. When designing the automobile inspection tool of the automobile inspection manufacturer, punch the position of the locating hole on the inspection concrete (subject to putting the locating pin bushing), and give the coordinates of the locating hole. At the same time, good rigidity and distribution in the workpiece position of reasonable arrangement chuck positioning gaskets and activity, to ensure the workpiece firmly positioning design to reduce the number of clamping point, ensure chuck work activities do not interfere with other parts, and considering the worker is easy to operate, zui terminal positioning gasket surface center of the body coordinates are presented.
When the precision of the hole to be measured is high, the plug gauge and bushing should be used to locate the hole. In the large covering parts of the body, the automobile inspection tools of automobile inspection manufacturers have been gradually replaced by advanced automated inspection methods (such as online inspection system), but for the detection of small stamping parts produced in large quantities, China's automobile manufacturers still mainly rely on the automobile inspection tools of automobile inspection manufacturers.
