Straight groove; the first adjustment block (2) is a rectangular long strip, and there are four installation counter holes and four installation threaded holes on the rectangular long strip; the second adjustment block (3) is a rectangular long strip , there are four mounting holes and four mounting threaded holes on the rectangular strip, a straight groove is arranged at both ends of the rectangular strip, and the bottom surface of the straight groove forms an acute angle with the plane of the rectangular strip; the oblique block ( 4) It is a wedge-shaped plate, the end face of the wedge-shaped plate has a waist-shaped counterbore, and the angle between the slope of the wedge-shaped plate and the end face is an acute angle.
Description
technical field [0001] The invention relates to the field of mechanical test tooling, in particular to a mechanical test tool capable of eliminating connection gaps and increasing connection rigidity. Background technique [0002] When performing mechanical tests on aerospace products, it is usually necessary to transfer test tooling between the product and the test bench. The traditional test tooling is generally directly screwed to the product, and there is usually a gap between the test tooling and the product, which will easily lead to a decrease in the connection stiffness between the test tooling and the product, thus causing unnecessary damage to the product during the test. Contents of the invention [0003] In this regard, the present invention provides a mechanical test tool that can eliminate the connection gap and increase the connection stiffness, which can effectively eliminate the connection gap between the test tool and the product, and increase the connect...
