A parallelism and height dimension detection device

Abstract

The invention discloses a parallelism and height dimension detecting device which comprises an indication component and a measurement component, wherein the indication component is arranged on the outer side wall of the measurement component. The parallelism and height dimensional gauging device further comprises a reference calibrating block which is arranged on an upper reference face of the measurement component and used for calibration. Therefore, the parallelism and height dimension detecting device is simple in design and structure and can be used for conveniently, extensively, quickly and accurately detecting the parallelism and height dimension of an end face relative to the reference face in industrial production; and moreover, the height error value can be read out directly, thereby greatly improving the production detection efficiency.

Description

technical field [0001] The invention relates to a detection device, in particular to a parallelism and height dimension detection device. Background technique [0002] Parallelism refers to the degree to which two planes or two lines are parallel. It is one of the important parameters that need to be strictly inspected and controlled in the production process. It is related to the mutual positional relationship between parts after assembly and the operation stability of equipment, such as air-conditioning compressors. There is a requirement for the parallelism of the end face relative to the reference plane in the end cap. There are many general-purpose measuring tools for the measurement of parallelism, and the methods are different for different parts, such as using a micrometer to measure multiple point dimensions or sliding on a flat plate with a dial indicator The method of measurement, but it is often impossible to measure with general measuring tools and conventional ...

[0002] Parallelism refers to the degree to which two planes or two lines are parallel. It is one of the important parameters that need to be strictly inspected and controlled in the production process. It is related to the mutual positional relationship between parts after assembly and the operation stability of equipment, such as air-conditioning compressors. There is a requirement for the parallelism of the end face relative to the reference plane on the end cover. There are many general-purpose measuring tools for the measurement of parallelism, and different parts have different methods, such as using a micrometer to measure multiple point dimensions or using a dial indicator to slide on a flat plate The method of measurement, but it is often impossible to measure with general measuring tools and conventional methods due to the limitations of the part structure, and it is measured with a three-coordinate measuring machine. The disadvantage is that it takes a lot of measuring points during the measurement, which is time-consuming. High, high environmental requirements, and it is not convenient for continuous measurement of the production line. If it is a single piece or small batch trial production and inspection, use three-coordinate measurement. If it is mass production and online inspection, use three-coordinate measurement. Delay production and reduce production efficiency
