A method for detecting the consistency of crankshaft eccentric shaft diameter in production site

Abstract

A method for detecting the consistency of the eccentric shaft diameter of a crankshaft at a production site. A measuring rod is arranged on the eccentric, one end of the measuring rod is connected with a V-shaped groove, and a group of contact blocks are embedded on the bottom surface of the V-shaped groove. The block and the A eccentric cylinder are solid, the measuring rod is inlaid with a fourth point contact block on the bottom surface of one end connected with the V-shaped groove, and the hardened measuring block is fixed at the bottom of the other end of the measuring rod; a group of contact blocks at the bottom of the V-shaped groove are against The shaft diameter of the eccentric cylinder A rotates the measuring rod clockwise until the fourth point contact block is against the outer surface of the eccentric cylinder B, and the measuring position of the measuring rod is determined. The present invention uses the three contact blocks on the V-shaped groove as the measuring rod. The support point of the initial position, the three contact blocks have been rotated against the eccentric cylinder A until the fourth contact block on the measuring rod is close to the surface of the eccentric cylinder B, determine the measuring position of the measuring rod, and then measure the second workpiece , compare the change of the indication value of the measuring table, and then analyze the deviation of the eccentric cylinder position of the two workpieces.

Description

technical field [0001] The invention relates to the technical field of crankshaft production, in particular to a method for detecting the consistency of crankshaft eccentric shaft diameters in a production site. Background technique [0002] The crankshaft is widely used in transmission components such as engines, compressors and precision reducers. The phase angle and eccentricity of the eccentric shaft of the crankshaft have high precision requirements and more consistent use requirements. There is no suitable detection method for the deviation of the position of the eccentric shaft of the crankshaft on site. SUMMARY OF THE INVENTION [0003] The present invention provides a method for detecting the consistency of the eccentric shaft diameter of the crankshaft at the production site in order to solve the above problems. [0004] The technical scheme adopted by the present invention: [0005] A method for detecting the consistency of the eccentric shaft diameter of a cr...
