Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings of the description, please refer to Figure 1 to Figure 9 , a measuring tool for detecting internal and external dimensions, including a dial indicator 11, characterized in that: it includes a main frame 1, a micro-moving measuring head and an adjusting measuring head;

[0029] The main frame 1 is composed of three sections, which are respectively from left to right: a left straight section, an arc section and a right straight section. In the middle of the left straight section, there is a large waist-shaped hole extending along the length direction. There is a small waist-shaped hole extending along the length direction on the right side of the shaped hole. 2 screw holes on the left straight section; there is a rectangular adjustment slot on the right straight section;

[0030]The micro-motion probe consists of 2 slide rails 2, a slider 3, a left probe mount 4...

Abstract

The invention belongs to the aerogenerator manufacture field and particularly relates to the measurement tool for measuring internal and external sizes and the usage method. The measurement tool comprises a dial indicator (11), a main frame (1), a tender movement probe and an adjusting probe. The measurement process comprises steps of regulating measurement depths of a left measurement probe (8) and a right measurement probe (14), installing a rubber band (7), combining measurement blocks, performing correction on the measurement tool and performing measurement. The invention provides a measurement design for detecting the external and internal sizes and a measurement method, which solves the problem that the shallow spigot with the shorter measurement surface cannot be detected, reduces the requirement for the operation staff, improves the detection efficiency and reduces the detection cost.

Description

technical field [0001] The invention belongs to the field of engine manufacturing, and in particular relates to the design and use method of a measuring instrument for detecting internal and external dimensions. Background technique [0002] In the engine production process, the production and application of various types of seams are extremely extensive. At present, the commonly used measuring equipment for detecting the size of general seams at the production site includes outer diameter micrometers, inner diameter micrometers, inner diameter gauges, articulated arms, three-coordinates, etc., but for some seams with special structures, such as shallow seams with short measuring surfaces Due to the limitation of the short measuring surface, ordinary measuring tools cannot detect it, especially the shallow seam where the middle structure of the seam is higher than the end face of the seam. Limited by the structure of the part, only special measuring tools or three coordinate...
