Deep blind hole inner diameter automatic measuring device and measuring method

Abstract

The invention discloses a deep blind hole inner diameter automatic measuring device and measuring method. The deep blind hole inner diameter automatic measuring device comprises a front measuring module, a middle stop module and a rear driving module. The front measuring module is connected with the rear driving module through the middle stop module. Firstly the front measuring module, the middlestop module and the rear driving module are placed in the deep blind hole to be measured from the inside to the outside in turn during measurement; secondly, the rear driving module pushes the front measuring module and the middle stop module to move in the deep blind hole, and the front measuring module completes the measurement of the inner diameter of the deep blind hole; and finally the middlestop module automatically stops the measuring device at the bottom end of the deep blind hole, and the rear driving module drives the front measuring module and the middle stop module to reversely move to the orifice. The non-contact front measuring module, the adaptive rear driving module and the automatic middle stop module, are used so that automatic detection and commutation of the inner diameter of the deep blind hole within a certain range can be realized and the measurement accuracy and efficiency of the inner diameter of the deep blind hole can be enhanced.

Description

technical field [0001] The invention relates to an automatic measuring device for the inner diameter of a deep hole, in particular to an automatic measuring device and a measuring method for the inner diameter of a deep blind hole, belonging to the technical field of deep hole detection tools. Background technique [0002] As the application proportion of large integral workpieces in modern aircraft, ships, large precision instruments and other products continues to increase, the detection of deep blind holes also occurs frequently. Because the existing blind hole measurement method is difficult to meet the requirements of blind hole detection depth, and the detection unit of the existing deep hole measurement device is also inconvenient to detect the bottom of the deep blind hole, and there are many driving devices for the whole machine, which is not easy. To realize the automatic reversing of driving in deep holes, some automatic measuring devices suitable for deep blind h...
