Gear chamfering laser gauge

The utility model provides a gear chamfering laser gauge, which comprises a tooth profile positioning component, a rotatable working platform, an outline measurement device and a data acquisition and processing device; wherein a gear is arranged on the rotatable working platform, and is fixed by the tooth profile positioning component, the position and the dimensions of gear chamfering can be detected by the outline measurement device, and data is transmitted to the data acquisition and processing device through a data line. The gear chamfering laser gauge has the advantages that: an integral structure is simple, manufacturing cost is low, a non-contact measurement method is used, and advantages of visualization, intellectualization, high sampling rate, high precision and nondestructive measurement and the like are provided; measurement for multiple cross sections of the gear chamfering can be achieved at one step, moreover, positioning of all cross sections and measurement starting points can be precise, and influences of measuring results due to anthropic factors can be eliminated, and intellectualization and degree of automation are higher.
