Identification means is beaten perpendicularly to heavy automobile semi -axle work piece terminal surface

This is novel wades an identification means is beaten perpendicularly to heavy automobile semi -axle work piece terminal surface, including the rollgang, bear the frame, the positioning base, the positioning fixture, the lift stand, the direction slide rail, the carrier block reaches beats the mark device, it is articulated with the positioning base upper surface to bear the frame, bear the frame including the collet, stand and driving roller, the positioning fixture inlays in bearing the frame, the rollgang is totally two, the equipartition is at least if group's constant head tank on the rollgang, the lift stand is through direction slide rail and positioning base sliding connection, it is articulated with lift stand up end that the carrier block passes through revolving stage mechanism, it installs on the carrier block to beat the mark device. This novel one side can effectual improvement detect convenience, the detection efficiency of operation and detect the precision camshaft step face axial length to h
