For double-sided engraving, an engraving main shaft 8 is arranged below the rear side wall of a Z-axis lifting frame 68, a cutter arranged at the output end of the engraving main shaft 8 is longitudinally arranged, at the moment, a shearing fork telescopic frame 27 in a telescopic supporting mechanism 2 is firstly retracted and lifted to a certain height, after the pressing plate 36 and the turnover plate 46 are synchronously lifted, a double-sided engraved thick plate-shaped blank is clamped by the method, the shearing fork telescopic frame 27 is unfolded after the clamping is finished, the blank is driven to be lifted to the bottom surface by a workpiece lifting pressing structure 3 and a workpiece lifting turnover mechanism 4 to be attached to the top of the shearing fork telescopic frame 27, top surface processing can be started, after the top surface processing is finished, the blank is lifted again by the workpiece lifting pressing structure 3 and the workpiece lifting turnover mechanism 4, then the shearing fork telescopic frame 27 is retracted, after the turnover is finished, the shearing fork telescopic frame 27 is unfolded, the blank is driven to be lifted to the top surface by the workpiece lifting pressing structure 3 and the workpiece lifting turnover mechanism 4 to be attached to the top surface of the shearing fork telescopic frame 27, and the bottom surface can be processed, and the bottom surface can be automatically finished without manual attachment operation.
Example 2:
For the cylinder engraving processing, the engraving main shaft 8 is arranged at the bottom of the Z-axis lifting frame 68, and a cutter arranged at the output end of the engraving main shaft 8 is transversely arranged forwards, at this time, the shearing fork expansion frame 27 in the expansion supporting mechanism 2 is firstly retracted and lifted to a certain height, after the pressing plate 36 and the turnover plate 46 are synchronously lifted, the cylinder-shaped blank engraved on both sides can be processed after being clamped by the method, and the cylinder-shaped blank is processed after being clamped.
In the description of the invention, it should be understood that the terms "coaxial," "bottom," "one end," "top," "middle," "another end," "upper," "one side," "top," "inner," "front," "center," "two ends," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate description of the invention and simplify the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be configured and operated in a particular orientation, and thus should not be construed as limiting the invention.
In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "configured," "connected," "secured," "screwed," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed, mechanically connected, electrically connected, directly connected, or indirectly connected through an intermediate medium, and may be a communication between two elements or an interaction relationship between two elements, unless explicitly specified otherwise, and it will be understood by those of ordinary skill in the art that the above terms are in the meaning of the invention as appropriate.
Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
