Abstract

The invention discloses a method for measuring aperture by using a probe, which belongs to the technical field of machining, and is characterized by comprising the following steps of: a, classifying holes to be measured of a test piece; b, A-type hole measurement: calling a first probe through a machine tool to measure hole diameters [phi]1 and [phi]2 in two planes perpendicular to the hole axis in sequence, calculating a difference value delta between the [phi]1 and the [phi]2, and comparing the [delta] value with the hole diameter tolerance zone to obtain a diameter value of the A-type hole; and c, B-type hole measurement: setting a measuring point of a second probe to be far away from the lowest point of the inner wall of the hole, calling the second probe through the machine tool to measure the hole diameters [phi]3 and [phi]4 in two planes perpendicular to the axis of the hole in sequence, calculating the difference value delta between the [phi]3 and the [phi]4, and comparing the [delta] value with the hole diameter tolerance zone to obtain the diameter value of the B-type hole. The method can effectively avoid the influence of residual cuttings, accurately measures the diameter of the deep hole, improves the measurement precision, is simple and convenient in the whole measurement process, and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for measuring hole diameter by using a probe. Background technique [0002] With the development of numerical control machining and detection technology, there are more and more occasions where the probe is used to measure the aperture on the numerical control machine tool. For a hole, the machine tool usually only calls the probe once to complete the hole diameter measurement. In the single-machine processing mode, the operator always pays attention to the processing status of the workpiece, and calls the probe to measure the hole diameter after confirming the clean state of the hole to be measured, which can generally ensure the accuracy of the measurement results. However, with the development of automated processing and flexible manufacturing technology, more and more unattended processing methods appear on the production site, requiring good accuracy ...
