Method for detecting accuracy of left hinge of engine cover

Abstract

The present invention discloses a test tool for detecting the accuracy of the hinge of an engine cover. The test tool comprises a base, a first detection block, a second reference block, a second detection block and a first reference block. The first detection block and the second reference block are used for detecting the left hinge of the engine cover. The second detection block and the first reference block are used for detecting the right hinge of the engine cover. The first detection block, the second detection block, the first reference block and the second reference block are arranged on the base. The first detection block and the second detection block are respectively provided with a left hinge detection hole and a right hinge detection hole, wherein the left hinge detection hole and the right hinge detection hole are used for detecting the accuracy of the installation holes of the hinges of the engine cover. The first reference block and the second reference block are respectively provided with a right hinge positioning pin and a left hinge positioning pin, wherein the right hinge positioning pin and the left hinge positioning pin are used for installing and positioning the hinges of the engine cover. The invention also discloses a method for detecting the accuracy of the left hinge of the engine cover and a method for detecting the accuracy of the right hinge of the engine cover. According to the technical scheme of the invention, the left and right test tools for the hinges of the engine cover are integrated together. Therefore, the advantages of simple structure, light weight, simple and convenient detection method and the like are realized.

Description

technical field [0001] The invention relates to a method for detecting the precision of the left hinge of the engine cover. Background technique [0002] The inspection tool used to detect the accuracy of the engine cover hinge, the manufacturer of the engine cover hinge is equipped with a set of special inspection tools for the left hinge and the right hinge respectively, which is used for the inspection of hinge products in daily production. The method of use is mainly to place the hinge single product on the reference block with the holes aligned and tighten the positioning with the positioning pin, then push the sliding detection block to be close to the mounting surface on the movable side of the hinge single product, and insert the detection pin into the mounting hole to measure the position accuracy of the hole. And this kind of special inspection tool has the following deficiencies: (1) the inspection tool for detecting the accuracy of the left hinge of the engine co...

Problems solved by technology

And this kind of special inspection tool has the following deficiencies: (1) the inspection tool for detecting the accuracy of the left hinge of the engine cover and the inspection tool for detecting the accuracy of the right hinge of the engine cover are not universal; (2) the general engine cover hinge The weight of the inspection tool is 12KG, which is too heavy and inconvenient to move, and two people are required to carry one set; (3) The design is too complicated, such as super large reference blocks, sliding detection blocks, detection pins, etc., which are too complicated in actual use, It is cumbersome; (4) The inverted design is not conducive to observing the detection accuracy of the installation hole; (5) The manufacturing cost is high, and the cost of manufacturing a set of inspection tools is about 20,000 yuan

There are also deficiencies in the detection method using this special inspection tool. First slide the detection block, then insert the detection pin, and finally squat down to carefully observe the detection method of the detection hole, which makes the detection efficiency low.
