Measuring device, application thereof, measuring method and workpiece processing method

Abstract

The invention relates to the field of measuring tooling, and specifically relates to a measuring device, an application thereof, a measuring method and a workpiece processing method. The measuring device comprises a measuring main body, a contact and a dial gauge, wherein the measuring main body extends along a straight line, the contact and / or dial gauge are / is arranged on the measuring main bodyin a sliding and lockable manner, the contact is arranged perpendicular to the measuring main body, and the axis of the dial gauge is parallel to the measuring main body. The dimension of a standardpiece can be defined by the contact and the dial gauge during the measurement through reasonably setting the structure of the measuring device, then the dimension of the workpiece to be detected is measured, the difference between the standard piece and the workpiece to be detected can be obtained according to a comparison method, and the dimension of the workpiece to be detected can be obtained by combining the dimension of the standard piece and the difference. It is unnecessary to measure each workpiece by a three-coordinate measuring device in the above process, the dimension of other workpieces to be detected can be accurately obtained by only measuring the size of the standard piece by adopting the three coordinates, and the problems that the cost of three-coordinate measurement is high and that the production period is prolonged in the prior art are solved.

Description

technical field [0001] The invention relates to the field of measuring tooling, in particular to a measuring device and its application, a measuring method and a workpiece processing method. Background technique [0002] The detection of the seam size of the wind power ring gear has always been a difficult point in mechanical processing and detection. The main reason is that the measuring tools used for large ring gears have poor precision, which is greatly affected by each person's hand feel, and the measurement accuracy is not enough. As a result, it is impossible to accurately determine whether the size is correct during the processing and testing process. can meet the requirements. Although the three-coordinate measurement can be accurately measured, it needs a constant temperature for 24 hours, and the cost of large-scale three-coordinate measurement is as high as 3,500 yuan / h. During processing, it is impossible to remove half of the processing, and then go to the thr...
