Optical measuring device and method for measuring volume of combustion chamber of engine cylinder head

Abstract

The invention discloses an optical measurement device and method for measuring the volume of a combustion chamber of an engine cylinder cover, and the device comprises a bottom plate which is provided with a translation assembly. The translation assembly comprises an X-axis fixing piece fixedly arranged at the top of the bottom plate, a servo motor arranged on one side of the top of the X-axis fixing piece and an X-axis guide rail fixed to the other side of the top of the X-axis fixing piece, an X-axis sliding block is arranged on the X-axis guide rail in a sliding mode, and an XY-axis fixing piece is fixedly arranged at the bottom of the X-axis sliding block; a motor is fixedly arranged on the XY-axis fixing piece, the X-axis sliding block is fixedly connected with a Y-axis guide rail through the XY-axis fixing piece, the translation device and the rotating device are arranged, the position of a cylinder cover workpiece does not need to be changed in the measurement process, and four combustion chambers can be measured only by positioning once. Meanwhile, the three-dimensional laser measurement sensor realizes rapid, accurate and automatic measurement of the volume of the combustion chamber of the cylinder cover of the engine in a non-contact manner.

Description

technical field [0001] The invention belongs to the technical field of engine cylinder head volume measurement, and in particular relates to an optical measuring device and a method for measuring the volume of an engine cylinder head combustion chamber. Background technique [0002] The compression ratio of an automobile engine is the main factor affecting various performance indicators of the engine. The volume deviation of the combustion chamber of each cylinder of the engine is large, which will affect the consistency of the compression ratio of each cylinder of the engine. The poor consistency of the engine compression ratio will lead to poor combustion consistency of each cylinder of the engine, which will affect the stability of the engine operation, affect the power and torque of the engine, and affect the life of the engine and emission standards. The cylinder head combustion chamber volume is an important part of the engine combustion chamber volume. At present, d...
