Abstract

The invention provides a self-adaptive measuring device for the outer diameter of a camshaft and a measuring method thereof, which include a base, a telescoping mechanism, a guiding mechanism and a measuring mechanism. The guiding mechanism is a dovetail movable table, which can slide in the guide rail of the base; the telescopic mechanism is a reciprocating cylinder installed at the end of the base, and its piston rod and the dovetail movable table are fixed to each other, driving the dovetail movable table to slide in the guide rail; the measuring mechanism The pneumatic measuring head is installed on the dovetail moving table through the connecting rod, and can realize small sliding in the horizontal direction and small swinging in the vertical direction; the pneumatic measuring instrument of the measuring mechanism is connected to the pneumatic measuring head through a conduit to realize the measurement of the outer diameter of each journal of the camshaft. Measurement. The invention realizes self-adaptive automatic measurement of each outer diameter of the camshaft through a pneumatic device, reduces manual participation and labor intensity, and improves measurement efficiency and quality.

Description

technical field [0001] The invention belongs to the field of precision measuring equipment, and in particular relates to a camshaft outer diameter self-adaptive measuring device and a measuring method thereof. Background technique [0002] The camshaft is a part of the engine's valve mechanism, which is responsible for driving the opening and closing of the valves. Its function is to ensure that the engine regularly inhales fresh combustible gas mixture for the cylinders during operation, and discharges the burned exhaust gas out of the cylinders in time. If the outer diameter of the camshaft is too large or too small, the opening law of the valve will be destroyed, which will affect the accuracy of the gas distribution work and make it difficult to adjust the gap between the valve rod end and the tappet. Now there are pneumatic measuring instruments, micrometers and special camshaft measuring instruments for measuring the outer diameter of camshafts. Pneumatic measuring in...
