Abstract

The invention relates to the field of three-coordinate measurement, in particular to a method for measuring the structure size of an area of a large retainer, which comprises the following steps of: 1, measuring the actual inner diameter of a retainer product at the vertical part of the inner diameter end surface; 2, measuring and recording data of a horizontal part of the upper end face and an inclined part of the upper end face through a three-coordinate measuring machine; 3, constructing a cylindrical auxiliary surface through the three-coordinate measuring machine according to the data in the step 1, constructing a first conical auxiliary surface along the track of the inclined part of the upper end face according to the data in the step 2, and obtaining the data of a first section formed by the intersection point of the cylindrical auxiliary surface and the first conical auxiliary surface; and 4, obtaining the distance from the first section to a reference surface by taking the plane of the horizontal part of the upper end face as the reference surface. According to the method adopted by the invention, the measurement blind area of the three-coordinate measuring machine for the structure size of a small area of a large-scale retainer is solved, and the structure size of the small area of the large-scale retainer is measured by applying a reverse structure method.

Description

technical field [0001] The invention relates to the field of three-coordinate measurement, in particular to a method for measuring the structural size of a small area of ​​a large cage product. Background technique [0002] In the process of producing large cage products, it has always been a difficult problem to measure the structural dimensions of some small areas. Because the size measured by the structure is required, the measured value cannot be directly detected by ordinary measuring instruments, and it is often necessary to use a coordinate measuring machine, a profiler, or a projector to measure. However, due to the large-scale cage products we process, the structural size needs to be measured after turning. However, the weight of the large-scale cage after turning reaches 600 catties, and the outer diameter of the product is greater than 1 meter. Placement, in the past, this kind of situation can only be verified through samples, or the product is destroyed and a se...
