Checking instruments and measuring method for detecting vehicle door hinge accuracy

Abstract

The present invention discloses checking instruments for detecting vehicle door hinge accuracy, the checking instrument includes horizontally arranged measuring surface, upon which is provided with a plurality of first mounting holes corresponding to first hinge mounting holes of hinge longitudinal mounting surface, the measuring surface is provided with a plurality of second mounting holes corresponding to second hinge mounting holes of the hinge horizontal mounting surface; the first mounting hole is fastening connected with the first hinge mounting hole via fastening screw; also including scribing pin inserted in the first mounting hole for scribing on the upper fastening surface, gap injection gape for measuring gaps among surfaces; measuring block with pre-set scale for measuring gap size between the hinge axis and measuring surface. The vehicle door checking instruments can detect hinge accuracy simply and smartly in imperfect analysis steps of vehicle daily production, therefore, being able to avoid adverse effect caused by hinge accuracy inadequate to the vehicle door mounting in early production.

Description

technical field [0001] The invention relates to a checking tool, in particular to a checking tool and a measuring method for checking the accuracy of a car door hinge. Background technique [0002] The common phenomenon in the mass production of automobiles in the prior art is that the door clearance level difference includes: front and rear door deflector H and B direction level difference and poor clearance, rear door and rear fender clearance poor, rear door and rear fender level difference poor , The difference between the front and rear door sections is poor; the main factors that cause the bad surrounding of the door are the accuracy of the car body, the accuracy of the door assembly, the accuracy of the door installation and the accuracy of the hinge, among which the influence of the hinge accuracy is the most direct factor. [0003] Hinge accuracy includes T-direction accuracy, B-direction accuracy, H-direction accuracy, hinge and door matching surface accuracy, T, B...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem that the existing technology cannot effectively detect the accuracy of the door hinge in daily production and affect the installation effect of the door hinge, and provide a detection tool and a measuring method that can detect the accuracy of the door hinge at any time following the production progress
