Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing: figure 1 with figure 2 As shown: In the observation window 9, two strip-shaped protective sheets 8 are respectively installed on the driving rack 6 and the driven rack 7 in the gear transmission mechanism; the hand wheel 1 and the driving bevel gear 2, driven bevel gear 3, The driving gear 4, the driving rack 6, the driven gear 5, and the driven rack 7 are connected by gear transmission, and drive two strip-shaped protection sheets 8 to be horizontally placed in the driving rack seat 10 and the driven rack seat 11 respectively. move.

[0012] When working, when part of the protective sheet on the observation window 9 is contaminated by metal molecules and cannot be observed, the driving bevel gear 2 is driven by rotating the hand wheel 1, and the driving bevel gear 2 is transmitted to the driving gear 4 through the driven bevel gear 3, and the driving gear 4 On the one han...

Abstract

An observing protector for electron-beam welder features that two strip-shaped protecting sheets in the observing window are installed in gear mechanism and can respectively and horizontally move in the observing window synchronously. When part of protecting sheet is polluted by metal moleculae, turning the gear can move it for normal observation by use of the un-polluted part.

Description

technical field [0001] The invention is an observation and protection device for an electron beam welding machine, which belongs to the improvement of the observation structure of the welding machine. Background technique [0002] In the electron beam welding machine, the state and process of metal welding must be observed through the observation window. However, due to the local high temperature during metal welding, a large number of metal molecules evaporate, polluting the surface of the optical glass component of the observation window and making it impossible to observe. The existing solution is to add a piece of circular plate glass as a protective sheet before the optical glass element of the observation window, and ensure observation by replacing the protective sheet. Its disadvantage is that the protective sheet needs to be replaced every time observation, which is troublesome to change, inconvenient to operate and easy to jam the protective sheet. Contents of the...
