A cylinder liner wall thickness detection device

Abstract

The utility model discloses a kind of cylinder liner wall thickness detection devices of detection device technical field, comprising: adjustable length's centering frame, both sides of the centering frame are equipped with briquetting, further include driving unit. In the utility model, the high-precision coincidence of cylinder liner axis and centering frame center line is realized by the synergic effect of centering frame and driving unit, using double-end hydraulic rod synchronous drive two sides briquetting clamping cylinder liner, in combination with pressure sensor real-time feedback clamping force, rotating frame drives detection unit circumferential motion, so that two distance detectors can gather multiple sets of wall thickness data along the same horizontal plane, effectively eliminate the measuring point not coplanar error caused by traditional manual operation, the design solves the technical problem that multiple measuring points are difficult to be coplanar, ensure that detection result truly reflects the same section wall thickness distribution, significantly improve measurement accuracy and data reliability, provide key basis for cylinder liner quality determination.
