Structural device capable of quickly removing and installing engine combustor windows

Abstract

The invention discloses a structural device capable of quickly removing and installing engine combustor windows. Two visual windows include a glass window on the top of an extended piston and a glass cylinder sleeve on the side surface of a combustor. The structural device is of the structure that a cylinder cover is supported by an upright post, the glass cylinder sleeve is arranged between the cylinder cover and a sliding sleeve, the inside diameters of the two sleeves are the same, the glass cylinder sleeve is positioned in a rabbet in the top surface of the sliding sleeve which is fixed on a support flat plate, screw nuts are symmetrically installed on both sides of the flat plate, and screws are screwed into the screw nuts to form a transmission pair. The screws are screwed to descend / lift, so as to drive the circular glass cylinder sleeve arranged in the rabbet of the sliding sleeve to move up and down, so that quick removal and installation are realized. A screw sleeve is arranged on the upper end of the extended piston, and the glass window is arranged in the middle of a piston ring on the top of the extended piston. The screw sleeve is unscrewed, so that the glass window can be taken out from a side hole of the extended piston. By using the structural device, the engine combustor windows can be quickly removed, the structural device has the advantage of good sealing performance, and the experiment efficiency is improved.

Description

technical field [0001] The invention belongs to the structural technology of internal combustion engines, and in particular relates to a structural device capable of quickly disassembling and assembling a visual window of an engine combustion chamber. Background technique [0002] In the research of engine combustion technology, in order to be able to observe and understand the flow field, mixture formation and combustion in the cylinder during the working process of the engine combustion chamber in real time, the metal cylinder liner on the engine was replaced with a glass cylinder liner, and the metal piston The central top of the model was replaced by an extended piston with a glass window. This allows real-time observation through windows from the sides and bottom of the combustion chamber. The window is made of quartz glass with high light transmittance, high hardness and wear resistance, and the laser can be injected into the cylinder from the side and bottom of the c...
