Problems solved by technology

[0003] However, some thin-walled cones are multi-angled and have arcs. Due to the complex shape, accurate measurement of wall thickness is difficult, and it is impossible to measure manually with ordinary calipers; electronic instruments or ultrasonic thickness gauges are used, and the arc surface of the cone affects the measurement. Accuracy, the measurement efficiency of three-coordinate equipment to measure various parts of the entire cone surface is too low, and the cost is too high

Abstract

The invention discloses a wall thickness measuring device and a measuring method. The wall thickness measuring device comprises a base, and an operating component, a rear positioning component, a front positioning component and a measuring rod component which are mounted on the base. The rear positioning component and the front positioning component are used for clamping and positioning a work piece. The measuring rod component is equipped with a dial indicator and a measuring rod. During measurement of wall thickness of a work piece, the contact center of the dial indicator on the outer wall of the work piece and the contact center of the measuring rod on the inner wall of the work piece are of equal height as the central axis of the work piece, and the contact center line of the dial indicator and the contact center line of the measuring rod are in a straight line. The operating component is used for adjusting the measuring point positions of the dial indicator and the measuring rod. Through the device and the method, large-area and multi-point measurement of the wall thickness of parts at any position is realized. Moreover, the device and the method have the advantages of accurate and reliable measurement, compact structure, and high efficiency of measurement.

Description

technical field [0001] The invention relates to a wall thickness measuring device and a measuring method, which are particularly suitable for conveniently measuring the wall thickness of a multi-angle cone with arcs and requiring high dimensional accuracy. Background technique [0002] The shape and size requirements of some key parts of flying objects are very high. For example, the wall thickness tolerance of thin-walled conical parts is often required to be within 0.05-0.10mm. Excessive wall thickness tolerances will directly affect the performance of the product. Therefore, the wall thickness of parts Thickness measurement is a key point in the process. [0003] However, some thin-walled cones are multi-angled and have arcs. Due to the complex shape, accurate measurement of wall thickness is difficult, and it is impossible to measure manually with ordinary calipers; electronic instruments or ultrasonic thickness gauges are used, and the arc surface of the cone affects th...
