An inclination measuring device and method for a cylinder head inclined hole

Abstract

A device for measuring the inclination of inclined holes of cylinder covers comprises a light sensing plate and a parallel light source, wherein the light sensing plate is fixed in the horizontal direction, and the parallel light source is located above the light sensing plate. A cover conveying mechanism is located between the light sensing plate and the parallel light source. The cover conveyingmechanism comprises a conveying belt and a driving wheel. The cylinder covers are arranged on the conveying belt at equal intervals, and the driving wheel drives the conveying belt to move and is connected with an intermittent movement mechanism. The use method of the device is as follows: the angle of the parallel light source is adjusted to be consistent with the required inclination of the inclined holes of the cylinder covers; the cylinder covers are arranged on the conveying belt at equal intervals. The conveying belt drives the cylinder covers to move and stops when being in alignment with the parallel light source, an oval is presented on the light sensing plate, and the long axis length of the oval is measured and recorded; whether the inclination of the corresponding inclined holes of the cylinder covers meets the requirement is calculated and analyzed; and the inclination of the inclined holes of the cylinder covers is measured by means of the principle of parallel light source imaging. The precision is high, the cylinder covers are driven by the conveying belt to move, on-line detection is achieved, and the detection efficiency is high.

Description

technical field [0001] The invention relates to an inclination measuring device and method for an inclined hole in a cylinder head. Background technique [0002] The cylinder head belongs to the gas distribution mechanism in the structure of the internal combustion engine. It is used to close the upper part of the cylinder, and forms a gas chamber with the cylinder and the piston. For gasoline engines, the cylinder head is also equipped with a mounting hole for fixing the spark plug. The spark plug mounting hole is set at a certain inclination angle to the cylinder head mounting plane. During quality inspection, it is necessary to detect whether the slope of the cylinder head slant hole is Up to the standard, the current detection device is generally tested by inserting the pin into the detection body. This operation method can only detect a single cylinder head, and the efficiency is low. At the same time, the accuracy of the physical detection method needs to be improved. ...
