Engine cover assembly checking fixture

Abstract

The invention discloses an engine cover assembly checking fixture. The fixture comprises a reference plate; the reference plate is provided with a detection block continuously arranged along the edgeof a cover; the reference plate is provided with an inner plate positioning mechanism and a covered edge bottom positioning mechanism, wherein the inner plate positioning mechanism and the covered edge bottom positioning mechanism are located at the inner side of the detection block, the inner plate positioning mechanism is used for positing the inner plate of the cover, and the covered edge bottom positioning mechanism is used for positioning the bottom of the edge of the cover; the reference plate is also provided with a covered edge side portion positioning mechanism which is located at theouter side of the detection block and is used for positioning the outer side of the edge of the cover; the reference plate is further provided with a hinge positioning mechanism corresponding to the hinge of the cover, a front end clamping mechanism which is matched with the front part of the cover, and an inner plate hole positioning mechanism which is matched with the inner plate hole of thecover; and the bottom of the reference plate is provided with a plurality of supporting legs that can lift and descend and rolling wheels corresponding to the positions of the supporting legs. With the engine cover assembly checking fixture of the present invention adopted, four states of the engine cover during manufacture can be simulated, so that production links which finally cause the clearance and surface difference of the engine cover can be judged.

Description

technical field [0001] The invention belongs to the field of engine cover detection, in particular to an engine cover assembly inspection tool. Background technique [0002] There are generally "four doors and two covers" on the car, and the four doors are the left front door, the right front door, the left rear door, and the right rear door. The two covers are the engine cover and the trunk cover. The mechanism of "four doors and two covers" is similar. It is generally composed of an inner plate and an outer plate. A press is used to press the inner plate and the outer plate into one body through an edge-wrapping mold. The inner plate is generally welded with various nuts that need to be assembled. In addition, the inner panel is generally uneven, which mainly plays the role of strengthening the strength of the inner panel; the outer panel is a smooth single piece, which mainly plays a decorative role, so that the appearance of the whole vehicle is coordinated and beautifu...

Problems solved by technology

However, the benchmarks for judging the gap and surface difference of the engine cover are inconsistent in each production link. Currently, the existing inspection tools cannot find out the production link that affects the gap and surface difference, which is not conducive to the improvement and improvement of the gap and surface difference of the engine cover.
