Abstract

The invention discloses a check tool for the runout and flatness of the end surface of the cylinder hole spigot of a cylinder block, which includes a support shaft, a guide stub, a measuring tool, and a gauge frame. The guide stub is combined with the lower end of the support shaft, and further includes A taper reference plate, the meter frame is combined on the upper end of the support shaft; the taper reference plate is combined on the upper part of the support shaft and between the meter frame and the guide short column; the measuring tool is assembled on the End of watch stand. The inspection tool has a simple and compact structure, can quickly and accurately detect the runout and flatness of the end face of the cylinder bore seam of the cylinder block, ensures stable and controlled product quality, and improves inspection efficiency.

Description

technical field [0001] The invention relates to the field of inspection fixtures, in particular to a inspection fixture for the runout and flatness of the end face of a cylinder bore seam of a cylinder block. Background technique [0002] The end face runout and flatness of the small plane of the cylinder bore of the cylinder block are very high, the end face runout is 0.03mm, the flatness size is not allowed to exceed 0.01mm, and only the inner height and outer height are allowed (for the center of the cylinder hole) ), if the two dimensions are not well controlled, it will lead to poor contact between the shoulder of the cylinder liner and the seam surface of the cylinder bore, resulting in water leakage due to poor sealing. Cracks, broken necks and other major failures. [0003] The traditional way to measure the end surface runout of the cylinder hole seam facet is to use the three-coordinate detection method, but the three-coordinate detection method is time-consuming ...
