Abstract

The invention relates to a total run-out comprehensive measuring instrument, comprising a base part, a head frame part, a measuring slide plate mechanism, a measuring device, an axial measuring position changing mechanism, a radial measuring position changing mechanism, a control circuit and a computer. The right and the left ends on a base are respectively provided with the head frame part and a right tip device; the measuring slide plate mechanism capable of transversely moving is mounted on the middle of the base; a measuring slide plate transmission mechanism is mounted between the measuring slide plate mechanism and the base part; a measuring device is mounted on the measuring slide plate mechanism; the axial and radial measuring position changing mechanism is arranged on the measuring device; the sensing signal output terminal of the measuring device is sequentially connected with the control circuit, the computer and a stepping motor driving circuit; and the output terminal of the stepping motor driving circuit is connected with a head frame driving motor and a slide plate driving motor. The total run-out comprehensive measuring instrument combines mechanical control, data collection and data processing into a whole, and realizes automatic data collection and processing of shaft parts through computer control automation, thereby having convenient operation and control and higher energy efficiency ratio.

Description

technical field [0001] The invention relates to a tolerance measuring instrument for shaft parts, in particular to an automatic comprehensive detection for tolerance items such as straightness, roundness, end surface circular runout, radial circular runout, end surface full runout, axial full runout, etc. instrument. Background technique [0002] Due to the lack of full runout tolerance testing equipment, designers rarely mark full runout tolerance items on product drawings. The full runout error of shaft parts has a direct impact on the working accuracy and life of the machine, and it has even more impact on machines and precision mechanical instruments that work under high temperature and heavy load conditions, such as the spindle of high-precision CNC lathes. Runout directly affects the accuracy of the machined parts. In view of this, a full runout comprehensive inspection instrument is designed, which uses a stepping motor to drive the shaft parts to rotate, a linear d...
