Problems solved by technology

The position detection and evaluation methods for these holes usually use three-coordinate detection. The workload of detection is large. Due to the limitation of the three-coordinate travel and the structure of the parts, it is difficult to detect the position of these holes. The three-coordinate detection of these hole positions has been used. become a bottleneck in the production process

Embodiment 1

[0045] The following takes an engine casing part as an example to describe in detail a method for detecting the position degree of a porous system provided by the present invention.

[0046] like figure 1 As shown in the figure, the receiver part includes a first sub receiver, a second sub receiver and a third sub receiver from left to right. The three sub receivers are formed by welding end to end. A coaxial circular spigot is provided, and the spigots of the three sub receivers are coaxial, and the circular spigots of two adjacent receivers are connected. After the three sub-cassettes are welded and formed, four spigots are formed from left to right, and each spigot is a mounting surface, which is a first mounting surface, a second mounting surface, a third mounting surface and a fourth mounting surface.

[0047] Since the sub-casing will be deformed after welding, each mounting surface needs to be turned and finished after welding. During processing, the end of the first s...

Abstract

The invention discloses a method for detecting the position degree of a porous system. The method for detecting the position degree of the porous system comprises the following steps that firstly, parts of a plurality of machining surfaces formed under the same machining reference condition are obtained, the hole groups of each machining surface is independently detected, and the machining reference of the hole set is different from the machining reference of the corresponding machining surface; then the diameter of the hole group of each machining surface is detected; secondly, at least one machining feature is selected on each machining surface to serve as a positioning mechanism, and a position degree detection tool used for detecting the machining hole set is prepared according to theselected positioning mechanism; and finally, the prepared position degree detection tool is assembled on the corresponding positioning mechanism, and the hole group of the machining surface is detected. According to the method for detecting the position degree of the porous system, a plurality of machining surfaces are subjected to decomposition detection, so that the problem of measurement of multiple machining surfaces at a long distance is solved, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a method for detecting the position degree of a porous system. Background technique [0002] At present, there are often multiple mounting edges on engine casing parts, and each mounting edge is distributed with a variety of hole systems, with a large number of holes and high precision requirements. The detection and evaluation method of the position degree of these holes usually adopts three-coordinates to detect, and the workload of detection is large. Due to the limitation of the three-coordinate travel and the structure of the parts, it is difficult to detect the position degree of the holes. become a bottleneck in the production process. SUMMARY OF THE INVENTION [0003] In view of the problems existing in the prior art, the present invention provides a method for detecting and evaluating the positional degree of a porous system, which improves the detection efficienc...
