Water blocking shaft device for single-shaft temperature control rotary table

Abstract

The invention discloses a water blocking shaft device for a single-shaft temperature control rotary table, belongs to the technical field of inertia technology testing, and aims to solve the problem of damage caused by condensed water generated at the mechanical interface of an incubator and a rotary table. According to the scheme, a water blocking shaft comprises an upper end surface, a lower endsurface, a main body, a water blocking plate, an upper threading hole and a lower threading hole. The upper end surface is connected with the extension shaft of the single-shaft temperature control rotary table, and the lower end surface is connected with a power main shaft in the single-shaft temperature control rotary table body; the upper end surface and the lower end surface are hollow; the main body is hollow; the upper threading hole and the lower threading hole are designed in the side surface of the main body; the water blocking plate is arranged in the main body inner cavity of the water blocking shaft. Condensed water can be effectively prevented from flowing into the rotary table, and then damage of the condensed water to electronic components of the single-shaft temperature control rotary table is reduced.

Description

technical field [0001] The invention belongs to the technical field of inertial technology testing, and relates to a water blocking shaft device used for a single-axis temperature control turntable. Background technique [0002] The research and development of test and motion simulation turntables have been carried out in China since the 1960s. At present, the main technical indicators of turntable equipment have approached or reached the advanced level abroad. [0003] As an important type of turntable equipment, the single-axis temperature-controlled turntable has the advantages of reliable performance and low price, and the annual market demand is huge. For a long time, when the thermostat works at low temperature for a long time, the condensed water produced by the temperature difference at the mechanical interface between the thermostat and the turntable will reduce the service life of the mechanical mechanism and electrical components of the turntable, and even affect ...

AI Technical Summary

Problems solved by technology

For a long time, when the thermostat works at low temperature for a long time, the condensed water produced by the temperature difference at the mechanical interface between the thermostat and the turntable will reduce the service life of the mechanical mechanism and electrical components of the turntable, and even affect the normal operation of the turntable. In the past, the turntable structure In most of them, there is no water-blocking shaft, and the power line from the inside of the turntable goes directly into the incubator through the extension shaft, so that the condensed water will fall directly to the inside of the turntable body along the direction of the wire, which will aggravate the damage of electronic components
