Automatic light leakage degree and closed gap detector of three-station piston ring and calibrating block thereof

Abstract

The invention relates to an automatic light leakage degree and closed gap detector of a three-station piston ring and a calibrating block thereof. A horizontal workbench is formed at the top of a stand, and is provided with a cantilever beam, a touch screen connected to the cantilever beam, a storage mechanism for storing the piston ring, a push plate positioned below the storage mechanism and a round turntable which is arranged in front of the storage mechanism and the push plate and rotatably inlayed on the horizontal workbench; a separation mechanism is arranged in front of the round turntable; a closed gap detection station, a discharge station and a light leakage degree detection station are formed on the round turntable by three inlayed standard gauges; a first charge coupled device (CCD) sensor corresponding to the closed gap detection station and a second CCD sensor corresponding to the light leakage degree detection station are respectively arranged above the horizontal workbench; and a light leakage degree detection illumination mechanism is arranged at the position below the horizontal workbench, corresponding to the light leakage degree detection station. By adopting the detector and the calibrating block, high efficiency, and the automatic detection and the separation of two indexes of the light leakage degree and the closed gap of small and medium sized piston rings are realized.

Description

technical field [0001] The invention relates to an automatic detection device for piston rings. In particular, it relates to a three-station piston ring light leakage degree and closed gap automatic detector and its calibration block used for the detection of small and medium-sized piston rings of automobile (or motorcycle) engines. Background technique [0002] The light leakage of the piston ring refers to the statistical information of the gaps that may exist along the contact circle that allow the passage of a specific intensity beam by pressing the measured piston ring into the standard ring gauge of the basic diameter of the cylinder, observing the combination of the two. The light leakage is actually the appearance of the airtightness of the piston ring combined with the piston and the cylinder wall when it is working. Because it is easy to detect, the light leakage information is usually used as one of the indicators to measure the quality of the piston ring. The cl...

Problems solved by technology

For small and medium-sized piston rings with small gaps, it is not competent

[0007] In addition, there are piston ring detection instruments designed by some institutes, or the principle has defects, which cannot meet the accuracy and repeatability of the detection, or cannot realize automatic detection, or are not suitable for small and medium-sized piston rings with high precision requirements.

In addition, in the past, the method of single-station, rotating ring gauge and fixed sensor was mostly used in previous designs, and the detection efficiency was greatly limited.
