The invention discloses a valve length detection device, which comprises a base. The base is provided with a valve stem vertical positioning fixture and a valve total length detection mechanism. The valve stem vertical positioning fixture comprises a valve stem positioning base. The valve total length detection mechanism comprises a guide rod vertically and fixedly arranged on the upper surface ofthe base. The guide rod is externally and movably sleeved by a sleeve. The sleeve is externally and fixedly connected with an installation arm horizontally. The outer end of the installation arm is provided with a valve length detection dial gauge right above the valve stem positioning base. A height adjustment mechanism is arranged between the sleeve and the guide rod. The invention also discloses a valve detection set device comprising the valve length detection device. The valve detection set device can realize detection of valve total length parameters and valve stem linearity, and has the advantages of being simple in structure, convenient and quick in operation and accurate and reliable in detection result and the like.
Description
technical field [0001] The invention relates to the technical field of production detection of automobile engine parts, in particular to a valve detection package and a length detection device thereof. Background technique [0002] The automobile engine can convert the chemical energy of fuel or other forms of energy into mechanical energy to provide power for the automobile. It is the heart of the automobile and belongs to a technology-intensive product. With the development of our country's economy, while the demand for automobiles is increasing day by day, the automobile industry has developed rapidly, and people's requirements for the performance of automobile engines are also getting higher and higher. [0003] In an automobile engine, the intake and exhaust valve is a component composed of a disc part and a rod part coaxial with the disc part. It is one of the key parts of the car engine and is the door of the engine combustion chamber. The key basic parts that seal t...
