Problems solved by technology

Non-contact measurement generally has high measurement accuracy, but the cost of equipment is high, the scope of use is narrow, and it cannot be fully automatic, which does not meet the needs of factory automated production
At present, the pipe fitting size measurement equipment that exists on the market often only measures a certain size of the inner diameter or outer diameter of the pipe fitting. Perform measurement inspection, low test efficiency

Embodiment Construction

[0037] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention with this.

[0038] Such as figure 1 As shown, in one embodiment of the present invention, a device for measuring inner and outer diameters of pipe fittings is disclosed. The measuring device includes: a test platform, an outer diameter measurement unit and an inner diameter measurement unit arranged on the test platform, and a test control combination Device 1. The test platform is used for clamping the pipe to be tested and provides a positioning reference for the inner diameter measurement unit and the outer diam...

Abstract

The invention discloses a device for measuring inner and outer diameters of a pipe fitting, and the device comprises a test platform, an outer diameter measuring unit and an inner diameter measuring unit disposed on the test platform, and a test control combiner. The measuring device adopts the image measuring technology to realize the measurement of the outer diameter of the pipe fitting and thelaser ranging technology to measure the inner diameter of the pipe fitting. Both test methods are non-contact measuring methods to ensure accurate and effective measurement results. The device is fully automated in test process, can not only realize simultaneous measurement of the inner and outer diameters of the pipe fitting, but also achieve independent testing of the inner or outer diameter ofthe pipe fitting, and greatly improves the test and detecting efficiency of the pipe fitting.

Description

technical field [0001] The invention relates to the structural measurement of pipe fittings, in particular to a measuring device for inner and outer diameters of pipe fittings. Background technique [0002] In the field of industrial production and manufacturing, the measurement of the inner diameter and outer diameter of pipe fittings is an important link in product production testing. The commonly used detection methods for the inner and outer diameters of pipe fittings can be roughly divided into two types: contact measurement and non-contact measurement. Contact measurement methods mainly include inner diameter micrometer, inner diameter micrometer, roundness meter, etc. Contact measurement methods often have errors caused by contact force or manual adjustment, and the measurement efficiency is relatively low. Non-contact measurement methods mainly include laser interferometer, laser lever method, Doppler effect method, image CCD imaging method, etc. Non-contact measu...
