The invention discloses an automatic cylinder wall thickness
measurement device based on a
laser sensor. The device comprises a
machine frame, a transmission unit, a rotating mechanism, a guide bearing mechanism and a measurement and adjustment mechanism. On one hand, the defect that a measurement instrument is abraded due to contact measurement is overcome, on the other hand, influences of unevenness of materials on
measurement precision are avoided, measurement efficiency and precision are greatly improved, and automatic pipelining measurement is easy to achieve. The
measurement device is improved in the following aspects: (1) the transmission structure of the
measurement device and the motion relation between the
laser sensor and a workpiece to be tested, (2) the distribution and automatic measurement
feeding mode of the
laser sensor, (3) automatic positioning, clamping and rotating of the workpiece to be tested and the anti-collapsing or anti-tilt structure, and (4) function
extensibility, measurement universality and implantation of an automatic
production line. The measurement device has the advantages of being simple in structure, high in reliability and easy to obtain.
