The invention relates to a product final inspection
machine. The
machine comprises a rack; the external detection module comprises a
transfer mechanism, and a mixed material detection mechanism, an over-spline detection mechanism, an outer
diameter detection mechanism, a length detection mechanism and a
helical tooth detection mechanism which are arranged in sequence, and the
transfer mechanism transfers parts in a previous process to a next process; the internal detection module comprises a turntable conveying mechanism, and an inner hole detection mechanism, a thread detection mechanism and an inner
diameter detection mechanism which are arranged in sequence, and the turntable conveying mechanism conveys parts and enables the parts to pass through the inner hole detection mechanism, the thread detection mechanism and the inner
diameter detection mechanism in sequence; and the
robot is used for transferring the to-be-detected parts from the charging tray into the mixed material detection mechanism, transferring the parts in the
helical tooth detection mechanism into the turntable conveying mechanism and taking down the parts in the turntable conveying mechanism. According to the device, detection work of all parameters of parts can be completed, feeding, discharging and transferring work of the parts can be automatically carried out, detection work of multiple parts can be carried out at the same time, and detection work of batch parts can be rapidly completed.
