[0037]The method of use of the present invention is:
[0038]When the left and right engraved are exactly the same relief, place the relief on the base 2 mechanically, and after the telescopic rod 24 of the stretching and clamping device 23 is stretched to determine the size, fix the relief body on the base 2, and then set the left and right reliefs. The rotation speed and direction of each base 2 are exactly the same. Then use the lifting bracket 3 to move back and forth to realize the front and back movement of the engraving device 4, use the fixed plate 5 of the engraving device 4 to move up and down to realize the up and down movement of the engraving assembly 6, and use the left and right movement of the connecting shaft 8 to realize the left and right movement of the engraving head 7 , So as to realize the three-dimensional movement of the engraving head 7 and realize the engraving at any position, to engrave the relief body at the same time. After engraving a certain position, the turntable 28 on the left and right base 2 will rotate synchronously to realize engraving in other positions. Realize the carving of relief. When you need to adjust different engraving products, for example, you need to replace the round or square sculpture, or replace the large or small relief body, such asFigure 7 As shown, the engraving tool 71 can be driven to rotate downward by the rotating motor 73, so as to realize the engraving on the surface of the relief and on the relief, which is convenient and quick.
[0039]When the left and right engraved products are mirror images of each other, the relief is placed on the base 2 by mechanical means, and after the telescopic rod 24 of the stretching and clamping device 23 is stretched to determine the size, the relief body is fixed on the base 2 and then set The rotation speeds of the left and right bases 2 are the same, but in opposite directions. The other engraving steps are the same as the above method.
[0040]The present invention uses the base 2 to fix the relief, uses the lifting bracket 3 to move back and forth to realize the front and back movement of the engraving device 4, uses the fixed plate 5 of the engraving device 4 to move up and down to realize the up and down movement of the engraving assembly 6, and uses the left and right movement of the connecting shaft 8 The left and right movement of the engraving head 7 is realized, so as to realize the three-dimensional movement of the engraving head 7 and realize the engraving at any position. The engraving accuracy is high, and the left and right reliefs can be engraved at the same time. The engraving efficiency is high, and the engraving functions are diverse and occupy less space.
[0041]The above are only preferred embodiments of the present invention, and do not limit the technical scope of the present invention. Therefore, all changes or modifications made according to the claims and specification of the present invention shall be covered by the patent of the present invention. Within range.
