[0025] On the basis of the above embodiment, in order to facilitate the adjustment of the distance between the two engraving devices so as to adapt to the spacing of the relatively processed raw materials, the utility model provides an adjustable setting between the adjacent first engraving device 4 and the second engraving device 6. Specifically, when engraving different types of raw materials, the high-precision screw transmission device drives the first engraving device 4 and the second engraving device 6 to move closer or farther from each other to adjust the corresponding processing positions, so that it can perform the engraving processing of multiple pieces of raw materials.

[0026] On the basis of the above-mentioned embodiment, the straight-row tool magazine 5 comprises: a tool magazine support 51, a first driving source 52, a protective component 53 and a tool loading fixture 54. The tool magazine support 51 is fixed on the gantry support 3, and is used to provide support for the installation of the first driving source 52, the protective component 53 and the tool loading fixture 54; the first driving source 52 is fixed on the tool magazine support 51, and is used to provide driving force for opening the protective component 53 and pushing out the tool loading fixture 54; the protective component 53 can be swingably arranged on the tool magazine support 51, and is used to cover the tool handle to prevent dust or processing waste from being attached to the tool; the tool loading fixture 54 can be movably arranged at the bottom of the tool magazine support 51, and the two sides are hingedly connected to the protective component 53; the first driving source 52 can drive the tool loading fixture 54 to move forward and extend, and at the same time drive the protective component 53 to open.

[0027] The double-head engraving machine of the utility model is provided with an openable and closable straight-row tool magazine on the gantry support mountain, so there is no need to stop the machine when engraving is completed. When the first driving source can directly drive the tool loading fixture to move forward and extend, the protective component can be driven to open at the same time to expose the tool. In this way, the equipment can freely switch the tool according to programming needs, reduce the time wasted in stopping to change the tool, further improve work efficiency, and save working time.

[0028] Based on the above embodiment, the first driving source 52 is a cylinder; the cylinder is fixed to the bottom of the tool magazine bracket 51 through a cylinder mounting seat, and a sensor is provided corresponding to the telescopic position of the cylinder to sense the telescopic state of the cylinder. In this embodiment, the sensor is a magnetic switch. In this example, the first driving source 52 can also be an electric type or a cylinder type or other reciprocating mechanical structure, which is not specifically limited here.

[0029] Based on the above embodiment, the tool loading fixture 54 includes a tool movable plate 541 which can be slidably arranged on the tool magazine bracket 51 through a linear rail; a tool clamp 542 is arranged in an array at one end of the tool movable plate 541; the tool clamp 542 is provided with a clamping portion 543 which can be deformed in the radial direction, and the clamping portion 543 is deformed in the radial direction under the action of an external electric field to press the tool on the tool clamp 542 to ensure that the tool is always accurately positioned during the movement without any deviation, thereby ensuring the efficiency of tool changing.

[0030] On the basis of the above embodiment, the workbench 2 is provided with an array of T-shaped mounting grooves; the workbench 2 is provided with a second clamping portion that is deformed in the vertical direction;

[0031] The first engraving device 4 and the second engraving device 6 are both provided with dust removal components, which are connected to dust collectors to evacuate the processing area so that the dust generated can be quickly collected.

[0032] Working principle: When in use, natural stone, glass, ceramics and other raw materials are placed on the workbench 2 and then the distance between adjacent raw materials is calculated according to the scale line, so as to adjust the distance between the first engraving device 4 and the second engraving device 6, so that the first engraving device 4 and the second engraving device 6 are both located above the center of the raw material. At this time, engraving can be started. The first engraving device 4 and the second engraving device 6 follow the gantry bracket 3 to move left and right, up and down, front and back to achieve replication, speed up work efficiency, and after the processing is completed, the tool can be quickly changed under the action of the straight tool magazine 5 for the next processing, thereby improving the processing efficiency.

[0033] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not used to limit the present invention.
