High temperature pressure assembly and high temperature adjustment method thereof during processing

Abstract

The application belongs to the field of elastic elements for sensors, and particularly relates to a high-temperature-resistant pressure assembly and a high-temperature adjustment method thereof in a machining process, which comprises an outer shell, an elastic element assembly and an inflated rear seat assembly; the elastic element assembly is arranged in the outer shell and fixedly connected with the inflated rear seat assembly; the elastic element assembly comprises a spring (3) and a bellows (2); the spring (3) is arranged in the bellows (2) and the front and rear ends of the spring (3) are fixedly connected with a bellows front cover (1) and the inflated rear seat assembly respectively; the inflated rear seat assembly comprises a rear chamber (10) and an inflation tube (6); an inflation port of the inflation tube (6) is communicated with the rear chamber (10); an inner cavity of the bellows (2) is communicated with the rear chamber (10); a force transmission member (12) is arranged at the front part of the outer shell; a top rod of the force transmission member (12) is fixedly connected with the bellows front cover (1) perpendicularly through a pressurizing tube (9). The application has the characteristics of low stress, high stability and long-term use.
