Rotary-shaft diameter and end-surface circular runout non-contact detection device

Abstract

The invention provides a rotary-shaft diameter and end-surface circular runout non-contact detection device, comprising a supporting base which is used for keeping a whole module to be installed and positioned, a clamping module which is used for positioning a to-be-tested rotary shaft, a horizontal linear driving module and a vertical linear driving module which are used for driving a detection module, a sensor detection module which is used for scanning a diameter of the to-be-tested rotary shaft and circular runout of an end surface of the to-be-tested rotary shaft, and a cylinder module that enables left and right ejector pins to tightly clamp and be separated from the to-be-tested rotary shaft. The diameter of the to-be-tested rotary shaft and the circular runout of the end surface ofthe to-be-tested rotary shaft can be detected only by placing the to-be-tested rotary shaft into the clamping module and starting the device. The invention aims at a commonly-used three-coordinate marking detection method in the detection of the diameter of the rotary shaft and the circular runout of the end surface of the rotary shaft, and designs a non-contact laser detection device capable ofobtaining measurement data in time.

Description

technical field [0001] The invention relates to the field of precision machinery, in particular to a detection device capable of accurately measuring the diameter of a rotating shaft and its end face circular runout without contact after machining the precision rotating shaft. Background technique [0002] The rotating shaft is a commonly used part for transmitting motion and torque in machinery. In high-speed precision machinery, the diameter of the rotating shaft and its end face circular runout have a great impact on the operation performance of the entire equipment; therefore, after the rotating shaft is processed, it is very necessary to detect its diameter and end face circular runout. [0003] At present, in the process of detecting the diameter of the rotating shaft and its end face circular runout, three-coordinate measuring equipment is used to make a meter, sort out and calculate the obtained data, and finally draw a conclusion; this method is cumbersome, ineffici...

Problems solved by technology

[0005] However, the detection tooling of the above-mentioned patent needs to manually adjust the lifting mechanism of the support seat, and after the adjustment is completed, it is necessary to manually adjust the dial indicator to detect the rotor circular runout, and the automatic detection of the rotor diameter and its circular runout cannot be realized.
