The technical scheme of the invention has the following advantages:
1. the invention provides a position degree detection device, which is suitable for detecting the position degree of a hole to be detected, which is arranged on a detection base and is positioned on an inner structure of a part, wherein the inner structure and an outer structure of the part blocked outside the inner structure enclose a cavity, the hole to be detected is positioned on the inner wall of the cavity, and the position degree detection device comprises: the auxiliary piece comprises an insertion part matched with the hole to be measured and suitable for being inserted into the hole to be measured, and a measuring part extending out of the outer side of the hole to be measured; the first detection piece is fixedly arranged on the detection base and comprises a first reference surface and a second reference surface which are mutually perpendicular and are respectively parallel to the axial direction of the measurement part; the second detection piece comprises a detection end close to the first detection piece and an auxiliary end close to the auxiliary piece; the detection end is provided with a first detection surface which is parallel to the first reference surface and can be close to or far from the first reference surface, and a second detection surface which is parallel to the second reference surface and can be close to or far from the second reference surface; the auxiliary end is provided with a first abutting surface and a second abutting surface which can abut against the peripheral wall of the auxiliary piece and are mutually perpendicular, the first abutting surface is parallel to the first detection surface, and the second abutting surface is parallel to the second detection surface; the distance between the first detection surface and the first reference surface when the first abutting surface abuts against the auxiliary piece is a first actual measurement distance, and the distance between the second detection surface and the second reference surface when the second abutting surface abuts against the auxiliary piece is a second actual measurement distance. Before detection, a first theoretical distance between a first detection surface and a first reference surface and a second theoretical distance between a second detection surface and a second reference surface can be obtained through measurement and calculation of a theoretical model (namely a standard part), so that a theoretical reference value of the first theoretical distance and the second theoretical distance is obtained, during detection, firstly, the part to be detected is fixedly arranged on a detection base according to a preset position, then an inserting part of an auxiliary part is inserted into a hole to be detected, then the second detection part is moved, a first abutting surface of an auxiliary end of the second detection part abuts against a measuring part, at the moment, a first actual measurement distance between the first detection surface and the first reference surface is detected by a measuring device, then a second abutting surface of an auxiliary end of the second detection part abuts against the measuring part, at the moment, the second actual measurement distance between the second detection surface and the second reference surface is detected by the measuring device, and the measured first distance and the first theoretical distance are compared, and the second actual measurement distance and the second theoretical distance are compared, so that a position deviation value to be detected, and a measured position measurement type of the hole to be detected is obtained. Because operating personnel only need insert the auxiliary member in the hole that awaits measuring earlier, offset second detection spare and measuring part, just can use measuring device to survey first actual measurement distance and second actual measurement distance, and the rethread compares first actual measurement distance and the first theoretical distance that will survey, and second actual measurement distance compares with the second theoretical distance to obtain position degree offset value, accomplish the measurement type detection of hole position degree that awaits measuring.
