Device of detecting axial and radial runout of shaft parts

Abstract

The present invention discloses a device of detecting axial and radial runout of shaft parts. The device comprises an installing panel used for installing and fixing all devices, and the installing panel is equipped with a tip automatic hole alignment device used for carrying out the automatic hole alignment on the shaft parts, a runout measurement device used for measuring the shaft neck radial runout and the shaft shoulder axial runout of the shaft parts, a man-machine interaction device used for acquiring, displaying, analyzing, determining and storing the runout detection data, an electrical control device used for installing and fixing all electrical parts in a detection mechanism and a friction transmission device used for transmitting the rotation of a motor shaft to the shaft parts. The beneficial effects of the present invention are that: 1, the runout error amounts at different positions are transmitted simultaneously by adopting the combination of a spring leaf structure and an alloy rod, the defect that a detection instrument needs to be adjusted repeatedly for a plurality of measurement points of a conventional deflection instrument is avoided, and the synchronous detection of the error amounts of three measurement points is realized.

Description

technical field [0001] The invention relates to a runout error detection mechanism, in particular to an axial and radial bidirectional runout error automatic detection mechanism and device in mass production of shaft parts. Background technique [0002] As a key component in the transmission system, the accuracy of shaft parts has an important impact on the performance of the entire transmission system. The radial runout of the journal where the bearing is installed affects the rotation accuracy of the shaft, and the axial runout of the shaft shoulder affects the positioning accuracy of the parts installed on the shaft. In the actual production process, especially in mass production, the runout error must be strictly controlled by testing equipment. The size of the amount. [0003] For the runout error of parts, the CON1-152 concentricity measuring instrument of domestic steel company, the NTY-TZ-002 concentricity measuring instrument of Japanese Nititoyo company and the MM...

Problems solved by technology

However, in view of the high cost of measurement, long time and high requirements for operators, most manufacturers of shaft parts currently use deflection meters or their improved instruments to detect runout errors.

The pendulum meter has the advantages of low cost and simple operation, but at the same time, it also has the problems of low detection efficiency, full participation of operators in the detection process, and low measurement accuracy.
