Description

Technical Field

[0001] The utility model relates to the technical field of engraving machines, in particular to a positioning device for an engraving machine. Background Art

[0002] Engraving machine is a relatively basic type of CNC machine tool, usually used to process non-metallic materials, divided into X-axis, Y-axis and Z-axis. Stone carving belongs to the category of sculpture, which is a form of plastic art that reflects society and has commemorative and symbolic significance. The initial engraving machines mostly used manual processing methods, but a large amount of dust was generated during the engraving process, and the labor intensity of the workers was very high. These dusts had a serious impact on the physical and mental health of the workers. Later, it evolved into a semi-automatic engraving machine, but this engraving machine has a small scope of application and poor engraving effect. In addition, when fixing the stone slab, the current engraving machine requires the worker to fix the stone slab firmly on the workbench through fixed fixings, which has certain requirements on the size of the processed stone slab and is inconvenient. For this reason, we propose a new positioning device for material processing for engraving machines.

[0003] In order to solve the above technical problems, a Chinese patent with announcement number CN207257194U in the prior art discloses a positioning device for material processing with an engraving machine, including a workbench, a support column is fixedly connected to one side of the top of the workbench, the top of the support column is fixedly connected to an axis, a rotating block is movably sleeved on the axis, one end of the rotating block is fixedly connected to a connecting column, one end of the connecting column is fixedly connected to an engraver, and the top of the workbench is fixedly connected to a first fixed seat.

[0004] Although the above-mentioned prior art solution is convenient for engraving materials from different angles and is adaptable to cylindrical materials of different sizes, the engraving materials are not limited to cylindrical shapes. Its two sets of clamping arms are respectively fixedly connected to one end of the connecting block and the fixed column. The shape of the clamping arms is fixed, which makes it difficult for staff to clamp and position engraving materials of different shapes, thereby affecting the practicability of the device.
