Precise grinding and polishing machine for sealed end face of airplane engine

Abstract

The invention discloses a precise grinding and polishing machine for the sealed end face of an airplane engine. The precise grinding and polishing machine comprises a shell, a gearbox, a first motor, a grinding liquid tank, a bearing plate, a liquid discharge pipe, a bearing box, a second motor, a third motor, a rotating wheel, a grinding plate installation plate and a grinding plate, and is characterized in that a supporting beam is arranged on the shell and provided with a guide rail, a sensor, a cylinder and a controller, the bearing box is connected with the cylinder through a lifting rod, a slide block, a spray nozzle and a stabilizer are arranged on the outer wall of the bearing box, a cushion block and a movable block are arranged in the bearing box, the second motor is arranged on the cushion block, and the third motor is arranged on the movable block. The grinding plate grinds a workpiece according to the track shaped like the Arabic number '8' under the effect of the second motor and the third motor, the grinding plate is prevented from making complete contact with the workpiece, the ground workpiece can be rapidly cooled, and meanwhile the grinding precision of the workpiece can be improved.

Description

technical field [0001] The invention relates to a grinding machine, in particular to a precision grinding and polishing machine for the sealing end face of an aircraft engine. Background technique [0002] At present, the quality requirements of the aircraft engine are extremely high, especially on the sealing end face of the engine, which directly affects the sealing performance of the aircraft engine. The existing grinding and polishing methods for the sealing end face of the aircraft engine are manual and mechanical. Manual operation There are problems of high labor intensity and low work efficiency. The mechanical operation generally adopts the method of full contact grinding between the grinding disc and the workpiece. This method makes the heat generated during the grinding process of the workpiece difficult to disperse, and high heat is easy to cause damage to the workpiece. At the same time It is also difficult to control the flatness of the grinding disc when in con...
