A structure for testing products in a closed space at room temperature

Abstract

The invention relates to a structure for testing, adjusting and data collecting of the products in a closed space under a normal temperature environment, which belongs to a sensor test and measurementtechnology. The structure comprises a product mounting bottom plate (1), a screw (2), a handle (3), a hinge support (4), a pressing block (5), a screw plug (6), an adjusting mounting seat (7), a magnetic steel mounting seat (8), a round head screw (9), a magnetic steel (10), a fastening screw (11), an adjusting rod (12), a bushing (13), an adjusting rod support (14), a fastening screw (15), an adjusting nut (16), a strut (17), a screw (18), an adjusting support (19), an adjusting bottom plate (20), an inner hexagonal screw (21), a cylindrical pin (22), a fixing frame (23), a dial indicator (24) and a dial indicator stand (25). The structure for testing, adjusting and data collecting of the products in closed space under normal temperature environment has the advantages of simple structure, convenient installation and high adjustment precision, and solves the working problems of normal temperature adjustment, on-line test, data acquisition and the like of the products under the specialclosed environment such as tight sealing and low temperature.

Description

technical field [0001] The invention belongs to the sensor test and measurement technology, and in particular relates to a structure for testing, adjusting and collecting data of products in a closed space under a normal temperature environment. [0002] technical background [0003] In the normal temperature environment, the installation adjustment, online testing and data collection of sensors in special closed environments such as closed high and low temperature require constant adjustment of the relative distance of the tested sensor to the magnetic field. In similar work in the past, the method of combining the push rod and the track was adopted, specifically, the sensor was pushed by the push rod through the observation hole of the high-temperature box to make a sliding movement on the track relative to the magnetic field carrier. However, when the unit measurement displacement required by the experimental program is very dense, each adjustment depends entirely on the o...

AI Technical Summary

Problems solved by technology

However, when the unit measurement displacement required by the experimental program is very dense, each adjustment depends entirely on the operator's technical proficiency. In addition, the tested sensor slides back and forth on the horizontal track, which will affect the quality of the outer surface of the tested sensor. At the same time, the manufacture and installation of the slide rail needs to be processed by precision machine tools. After the final assembly, it needs to be ground and adjusted on site. These reasons make the test results fluctuate greatly and the test cycle is prolonged
