Abstract

The invention relates to a fast torsion angle measuring bracket positioning device which comprises a positioning block, wherein the positioning block is semi annular and comprises a mounting part anda positioning part; the internal diameter of the mounting part is equal to the external diameter of a tester switching disc; the internal diameter of the positioning part is equal to the external diameter of a corner bracket; the circular centers of the internal diameters of the mounting part and the positioning part coincide with each other; a semi annular groove is formed between the mounting part and the positioning part; the bottom of the positioning part is a positioning plane; and the positioning plane is matched with the upper end face of the support arm of the corner bracket. The fasttorsion angle measuring bracket positioning device is precise in design and positioning, safe and reliable, and more convenient to test and mount and shortens the mounting and positioning time.

Description

technical field [0001] The invention relates to a positioning device, in particular to a fast positioning device for a torsion angle measuring bracket. Background technique [0002] At present, many aviation products need to do a series of tests before delivery and after repair to ensure the use requirements. For the torsional stiffness test of a torsion axis, it is necessary to install an Ω-shaped torsion angle measuring bracket on the torsion loading end of the part to be tested, and measure the displacement of the bracket arm when the torsion is added by playing a meter, and derive the torsion angle, and obtain The relationship between torque and rotation angle. Before the test, the corner bracket needs to be installed on the surface of the bolt head where the disc end of the test piece is fixed to the tester adapter plate, and the center of the upper semicircle of the semicircle section of the corner bracket is required to be in the axial direction of the test piece. c...
