Abstract

The invention discloses a system for measuring an inner diameter of a tubular workpiece. The system comprises a crawling transportation positioning sub-system, a data acquisition and control sub-system and a data processing sub-system, wherein when the inner diameter of a measured tubular workpiece is required to be measured, the crawling transportation positioning sub-system crawls in a pipeline of the measured tubular workpiece under the control of the data acquisition and control sub-system, and acquires measurement data of a pipeline section corresponding to a position to be measured when crawling to every position to be measured; the data acquisition and control sub-system acquires the measurement data which is acquired by the crawling transportation positioning sub-system and sends the measurement data to the data processing sub-system; and the data processing sub-system generates a required measurement result according to the received measurement data. By the adoption of the system for measuring the inner diameter of the tubular workpiece, the accuracy of a measurement result is improved, and the measurement efficiency can be improved.

Description

technical field [0001] The invention relates to workpiece measurement technology, in particular to a system for measuring the inner diameter of tubular workpieces. Background technique [0002] In the machining industry, the processing of tubular workpieces is the most common processing technology, such as artillery barrels for weaponry, oil and gas pipelines, and engine cylinder liners. In the processing of these tubular workpieces, the control and measurement of the inner diameter is directly related to the product performance of the workpiece and the safety of the whole machine system operation. [0003] At present, for the measurement of the inner diameter of the tubular workpiece, the contact measurement method is mainly used, that is, the manual measurement is carried out through the inner diameter micrometer. However, due to the influence of human factors in this measurement method, the measurement error is usually large, that is, the accuracy of the measurement resu...
