The inspection tool will drive the vane of the entire automotive industry!

Inspection fixture is a simple tool used by industrial production enterprises to control various sizes of products. It is suitable for mass-produced products, such as auto parts, to replace professional measuring tools, such as vernier calipers, depth gauges, etc. 1. Purpose     Through the formulation of "Technical Requirements for Inspection Fixtures (Measuring Support)", the inspection fixture (measurement support) can follow uniform technical standards and evaluation indicators during planning, design and manufacture, acceptance and use. 2. Scope of application     This technical requirement is applicable to vehicle body inspection tools and inspection tools for interior and exterior trim parts that are related to part profile dimensions or assembly dimensions with the body coordinate system. 3. Responsibility     Responsible for the preparation, maintenance, upgrade and distribution of this technical requirement.     The component supplier is responsible for the implementation and execution of this technical requirement in the planning, design, manufacturing, acceptance and use of the inspection tool (measuring bracket). 4. Provisions    4.1 Overview of the inspection tool (measuring support)    4.1.1 Definition of inspection tool (measuring support)     Inspection fixture is a special inspection equipment used to measure and evaluate the dimensional quality of parts. At the parts production site, the online inspection of the parts is realized through the inspection tool. For this reason, the parts need to be accurately installed on the inspection tool, and then the part profile and surroundings can be inspected by visual inspection, or measurement table, or caliper. Inspection pins or visual inspections visually inspect the holes of different properties on the parts and the connection positions between the parts and the parts, so as to ensure that the quality status of the parts can be quickly judged during trial production and start-up production. In this case, visual inspection or measurement can be used to judge: the deviation between the peripheral size and shape area and relative position of the part contour and the theoretical value of the inspection tool directly processed by CAD/CAM.      For some extremely important functional dimensions on the parts, it is also possible to use the gage for numerical testing. Usually, the precise coordinate values of the parts based on the body coordinate system cannot be obtained directly with the aid of the inspection tool, but the parts are placed on the inspection tool and measured by the coordinate measuring machine. The structure of modern inspection tools is designed to be used as a measuring support. But when the online inspection function of the inspection tool and the measurement bracket function cannot be satisfied at the same time, the online inspection function of the inspection tool should be satisfied first. The measuring bracket is an auxiliary bracket when measuring parts with a coordinate measuring machine. All supporting surfaces (points) and positioning reference surfaces (points) must be milled according to the CAD data of the part. The measuring bracket for some special parts should also It has the function of some checking tools.     4.1.2 Checking tools and measuring brackets can reasonably measure all data of parts based on valid product drawings and CAD data, and verifying and appraising the checking tools and measuring brackets with the aid of a three-coordinate measuring machine.     4.1.3 In the case of normal frequency of use and good maintenance, the service life of the inspection tool and measuring bracket should be guaranteed during the production cycle of the corresponding parts.
