Vacuum strobe frequency observation window

Abstract

The invention discloses a vacuum strobe frequency observation window comprising a rotating disc, a shell, an upper cover, a glass observation window and a motor. The rotating disc is located in the shell and is defined by two discs on the two layers of discs up and down, a cavity is formed between the two layers of discs up and down, the two layers of discs up and down use the circle centers as centers, each center is symmetrically provided with two or more straight seams, and the straight seams arranged on the two layers of discs up and down are in one-to-one correspondence; the glass observation window is fixed on the outer side of the upper cover, the motor is fixed on the outer side of the upper cover, a main shaft of the motor passes through the upper cover and extends into the shell,the main shaft passes through the rotating disc and is fixedly connected to the rotating disc, the upper cover and one side of the shell are fixedly connected, and the other side of the shell is fixedly connected to a vacuum chamber. By means of the vacuum strobe frequency observation window, splashing can stopped, an operator can conveniently observe the condition inside the vacuum chamber, thearea of the seams of the rotating discs is smaller than the area of the rotating discs, light capable of passing through the seams is greatly reduced, the light shielding effect is achieved, and observation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of vacuum smelting, and in particular relates to a vacuum strobe observation window. Background technique [0002] In the fields of vacuum smelting, vacuum heat treatment, and ion sputtering, the conditions in the vacuum chamber are observed through the strobe observation window. When the metal is melted, metal particles will be ejected from the surface, and the gas or low-melting point metal originally dissolved in the metal will also be released. It will eject, and these ejections can fly a long distance in a vacuum state. When they are sputtered on the vacuum observation window glass, they will form a film, which will block the observer's line of sight and make the operator unable to see the vacuum clearly. indoor situation. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a vacuum stroboscopic observation window. The te...
