Assembling method for precise mechanical parts based on clearance measurement

Abstract

The invention relates to an assembling method for precise mechanical parts based on clearance measurement and belongs to the technical field of mechanical assembly. The precise mechanical parts are parts, the form and location tolerance of which are not greater than 0.02 mm. The method comprises the following step: assembling two precise mechanical parts through clearance measurement, that is, assembling the inner surface of one of the precise mechanical parts and the outer surface of the other precise mechanical part. The method comprises the step of measuring the inner diameter of the firstprecise mechanical part and the outer diameter of the second precise mechanical part by adopting a three-coordinate detector to provide a basis for the assembling process in the later period. The precise mechanical parts assembled by the method are uniformly glued without local glue lack and glue leakage on the surfaces of the precise mechanical parts. The precise mechanical parts are assembled inposition, and the sealing property and the binding force of a combination body are good.

Description

technical field [0001] The invention relates to an assembly method of precision mechanical parts based on gap measurement, which belongs to the technical field of mechanical assembly. Precision mechanical parts refer to shape and position tolerances not greater than 0.02mm. The parts are assembled, and the inner surface of one precision mechanical part is mated with the outer surface of another precision mechanical part. Background technique [0002] Due to the high dimensional accuracy of precision mechanical parts, the requirements for assembly are high. The assembly methods in the prior art have the following deficiencies: [0003] (1) The assembly clearance of precision mechanical parts is too large or too small; [0004] (2) There is uneven glue coating on the surface of precision mechanical parts; [0005] (3) Partial lack of glue on the surface of precision mechanical parts; [0006] (4) Partial glue leakage on the surface of precision mechanical parts; [0007] (...
