AI Technical Summary

Technical Problem

Traditional methods for protecting the inner pores of the vacuum chamber in spectrometers are prone to causing orifice deformation, have low disassembly efficiency, and cannot adapt to different orifice diameters, making it difficult to guarantee the surface precision and cleanliness of the inner pores during sandblasting.

Method used

An inner hole protection fixture including a drive assembly and an expansion sleeve is adopted. The distance between the adjusting seat and the fixed seat is controlled by adjusting bolts, so that the expansion sleeve can be opened or closed. The inner hole is sealed by an arc-shaped petal and an annular elastic element, and an outer protective sleeve is added to protect the internal structure.

Benefits of technology

It enables rapid installation and adaptive sealing of inner holes with different diameters, avoiding damage to the inner holes during sandblasting and improving protection efficiency and cleanliness.

Abstract

This utility model discloses a protective fixture for the inner hole of a spectrometer vacuum chamber, including a driving assembly and an expansion sleeve fitted on the outer wall of the driving assembly. The driving assembly includes an adjusting seat and a fixed seat, which are connected by adjusting bolts. The distance between the adjusting seat and the fixed seat is controlled by adjusting bolts so that the expansion sleeve can be opened or closed. Using this fixture, the inner hole of the spectrometer vacuum chamber can be quickly sealed, avoiding damage to the inner hole surface during sandblasting.
