Background
The size of the piston pin hole is the key size of the piston, a reasonable fit clearance is kept between the piston pin hole and the piston pin, so that an enough lubricating oil film is ensured between the piston pin and the pin hole, dry friction occurs between the thin-surface piston pin hole and the piston pin, and generally, when the fit clearance between the piston pin and the piston pin hole is 6-8 mu m, the normal work of the piston can be ensured.
The dimensions associated with the piston pin bore also include the symmetry of the pin bore axis with the cylindrical axis (i.e., piston pin bore offset), the perpendicularity of the pin bore axis with the cylindrical axis, the distance from the pin bore axis to the top surface of the piston (i.e., high compression), the combustion chamber/valve pocket depth, and the like. If the symmetry and the verticality are out of tolerance, the contact pressure of the skirt part is increased when the piston moves in the cylinder sleeve, and the piston is abraded seriously; the compression height and the combustion chamber/valve pit depth dimension being out of tolerance can affect the parameters of doing work, thereby affecting the performance of the whole engine. Therefore, the key size of the piston needs to be strictly controlled, and unqualified products are prevented from being installed in the engine.
However, in the prior art, the relevant size of the piston pin hole is mostly measured by a plurality of manual sub-processes or is selected by using a general measuring tool, which not only wastes manpower, but also has more piston turnover times in the measuring process, easily causes the phenomena of collision, scratch and the like, and influences the qualification rate of products. The high-compression size needs to be measured by using a general measuring tool, and the high-compression size cannot ensure that all pistons are qualified in size because the efficiency is too low and only a sampling inspection mode can be adopted. Although some simple piston pin hole detection equipment also appears, the equipment can only measure a few small sizes generally, and pin hole air measuring heads are generally adopted and respectively inserted into piston pin holes on two sides during measurement of the diameter and the roundness of the pin holes, so that the measurement is carried out in multiple times, and the equipment is more complicated and has poorer detection accuracy.
