The present invention discloses an improved vehicle wheel rolling carving device, consisting of a left impressing system, a right impressing system, a lower synchronous clamping driving system, a left support system, a right support system, an upper synchronous clamping driving system and the like. The lower synchronous clamping driving system enables a vehicle wheel to rotate under the clamped state, the left support system moves towards the right, the right support system moves towards the left and thus left and right support rolls contact the rotating vehicle wheel; meanwhile, the upper synchronous clamping driving system enables two shafts II and two shafts III to clamp the wheel and apply auxiliary clamping forces to drive the vehicle wheel to rotate; and after the left and the right impressing system rise to different heights, impression carving can be performed on different positions of a back cavity of the vehicle wheel.

A rotary laser engraving device for retaining and rotating an object for engraving includes a frame, a first support assembly and a second support assembly mounted on the frame. To support the object the first support assembly includes a set of driven rollers and the second support assembly includes a set of free rollers, each being diagonally offset from the frame. The second support assembly is configured to slidably move on the frame to vary a longitudinal separation between the driven rollers and the free rollers. The second support assembly further includes a vertical adjustment assembly configured to move the free rollers vertically to vary a vertical separation between the driven rollers and the free rollers. In some aspects, the first support assembly also includes a fixed vertical adjustment assembly configured to move the driven rollers vertically to vary a vertical separation between the driven rollers and the free rollers.

A rotary laser engraving device comprising a frame having a centroidal axis and comprising a central bar arranged in a longitudinal direction and off set horizontally from the centroidal axis. A first support assembly is carried by the frame for supporting a first end of an associated object to be engraved. A second support assembly is carried by the frame for supporting a second end of the associated object to be engraved. A longitudinal adjustment mechanism is carried by the frame and being configured to restrict movement of the second support assembly in a longitudinal direction along the central bar. A vertical adjustment mechanism is carried by the frame and being configured to move the second support assembly vertically with respect to the central bar.
