Abstract

The invention relates to the technical field of flatness measurement, in particular to a flatness measuring instrument and method, which comprises a controller, a manipulator, a laser range finder and a measuring table for clamping a workpiece to be measured, the measuring table is located on a measuring station where at least one mechanical arm grabs and places a workpiece, and each mechanical arm is used for grabbing the workpiece to be measured from a blank position and placing the workpiece on the measuring table, and is also used for controlling the mechanical arm to grab and put down a workpiece qualified in measurement to a finished product position, or grab and put down a workpiece unqualified in measurement to a waste product position; the measuring station is located on a measuring track of the laser range finder, and the laser range finder is used for measuring a distance value between the laser range finder and the workpiece to be measured on the measuring station; and the controller is used for judging whether the workpiece to be measured is qualified or not according to the distance value measured by the laser range finder. The automation of each working procedure of workpiece flatness measurement can be realized, the measurement precision and the measurement efficiency are improved, and the labor cost is saved.

Description

technical field [0001] The invention relates to the technical field of flatness measurement, in particular to a flatness measuring instrument and method. Background technique [0002] In mechanical processing, it is often necessary to measure the flatness of the processed workpiece to verify whether the product is qualified. Most flatness measuring instruments need to be operated manually, which is not easy to use and requires relatively high professional knowledge of the operator. At present, there are several traditional measurement methods. The first one is to judge whether the flatness of the workpiece is qualified by placing the workpiece on the reference table and measuring the gap between the plate and the workpiece by visual observation or by adding a feeler gauge. This measurement method has low precision and relatively high labor intensity; the second widely used tool for measuring flatness is the three-coordinate measuring instrument, which has strict environmenta...
