Abstract

The invention of the valve girdle jumpiness detection utensil for the engine cylinder cap belongs to the technology area of the detection utensil in process of the automobile production. It comprises the body of the detection utensil and the dial indicator. A column which matches with the valve guide bushing is mounted at the front of said detection utensil, said dial indicator is approximately set at the middle of the detection utensil and its contactor staggers with the axial of the column, the free rotational locating steel balls are mounted on the detection utensil, and they are in the same circle with the end part of the dial indicator contactor, the center of said circle is at the extended line of the column axial. The invention is light in weight, easy to move, convenient to detect, furthersome to improve the production efficiency. It resolves the current problems of detecting instrument which is difficult to move, inconvenient to detect, big limitation, restraining the production efficiency.

Description

technical field [0001] The invention relates to an engine cylinder head valve ring belt runout inspection tool, which belongs to the technical field of inspection instruments in the engine production process. Background technique [0002] In the prior art, to detect the valve annulus of the engine cylinder head, that is, the jump between the valve guide and the 90° cone surface of the seat ring, the cylinder head needs to be fixed on a special detection instrument, and the volume of this instrument is large and inconvenient to move, so The detection of the cylinder head valve ring belt can only be carried out in a special detection place, which is inconvenient and limited, which limits the production efficiency. Contents of the invention [0003] The object of the present invention is to provide a light weight, easy to move, convenient to detect, and beneficial to improve production efficiency cylinder head valve ring beating inspection tool, which solves the inconvenience...
