Summary: The article is brief the machine tool precision that two kinds of concerned cylinder in introducing cylinder boring to machine locate detects method. Point out the simple and easy standard that raises precision of cylinder fixed position. Keyword: Boring treatment; Fixed position; Detect the graph in the law classifies date: TG534 document label piles up: The cylinder boring treatment in B vehicle repair uses boring machine of T716 vertical King Kong to finish normally. There is method of two kinds of locations commonly when boring crock, use the plane below cylinder body namely or use crankshaft opening fixed position. But, the cylinder axes verticality after boring depends on not only location method, and also depend on the geometrical precision of machine tool itself. Detect because of what this concerns precision to the machine tool the method wants correct. The graph shows 1 times detect a the method is a mistake. If the graph is shown 1 times, to detect place of boring machine of T716 vertical King Kong bumps into cylinder axes verticality, used express magnetic force fixed end panel leaves in boring head, measure dial gauge the head to be hit on workbench face, turn next strike a head, the jumpy quantity of transverse examination dial gauge, again convert arrives the method on standard length. The result that place of this kind of method detects, it is axes of boring head main shaft actually the appoints direction verticality error to workbench face, not be boring head feed be in between direction and working mesa the verticality that appoints direction, accordingly, measure gotten result with place of this kind of method, the direction that assures axes of place boring cylinder with the machine tool is without a relation between precision, be a kind of mistake detect method. Detect correctly the method ought to detect the verticality between the sliding stock slideway of the machine tool and workbench face. The graph shows 2 times detect the method is correct, it uses square to serve as contrast fiducial, use measure a law to finish relatively. Be about to magnetic force is expressed fixed in boring head lower end, secure boring head do not turn. Set square range like graphic representation, make dial gauge measures a head to be hit on square face. Head of the boring that start rises quickly fall system, the fluctuant cost of dial gauge is examined inside formulary height limits. square transfer after 180 ° , duplicate afore-mentioned operations, two dial gauge fluctuant value is pressed " GB " in provides computational method consideration, can reach verticality error reachs angle square error. Afore-mentioned methods can be used at the machine tool to repair not only, still can apply the to cylinder body adjustment when bumping into crock of fixed position. That is to say should know the size of the verticality error of boring head slideway and workbench face and way only, measure before boring crock crankshaft the size of aperture axes and parallelism alignment error of plane of cylinder body bottom and direction, can pass in plane of cylinder body bottom one aspect of the matter fills up the spacer with proper ply to realize crankshaft the adjustment with aperture axes and boring machine completely perpendicular slideway, obtain taller cylinder verticality to machine precision.
