[0030] The frame 1 is provided with two bilaterally symmetrical bases 2 and a lifting bracket 3. The frame 1, base 2, and lifting bracket 3 are made of stainless steel. The lifting bracket 3 is movably connected to the frame 1. The lifting bracket 3 is provided with an engraving device 4, which is movably connected to the lifting bracket 3. The engraving device 4 includes a fixed plate 5 and an engraving assembly 6 movably connected to the fixed plate 5. The engraving assembly 6 includes a connecting shaft 8 and an engraving head 7 disposed at both ends of the connecting shaft 8. The engraving head 7 includes an engraving tool 71, an engraving base plate 72, and a rotating motor 73. The engraving base plate 72 is fixed to the connecting shaft 8. The engraving tool 71 is provided with a rotating shaft 74, which is connected to the rotating motor 73 via a conveyor belt drive. After the rotary motor 73 rotates, the force is transmitted to the rotating shaft 74 through the conveyor belt, and the rotating shaft 74 will realize a specific angle of rotation, generally 90 degrees, so that the cutting head of the engraving tool 71 moves forward to the cutting head downward, and the direction of the cutting head is adjusted to realize different relief engraving. When the cutting head of the engraving tool 71 is downward, smaller objects can be engraved, and when the cutting head of the engraving tool 71 is forward, round sculptures can be engraved, which are used to engrave large surfaces, and the engraving applicability is strong. When engraving, the present application fixes the relief through the base 2, uses the lifting bracket 3 to move back and forth to realize the movement of the engraving device 4 back and forth, uses the fixed plate 5 of the engraving device 4 to move up and down, realizes the up and down movement of the engraving component 6, and uses the left and right movement of the connecting shaft 8 to realize the left and right movement of the engraving head 7, thereby realizing the three-dimensional movement of the engraving head 7 and realizing engraving at any position.

The function of the limit drag chain 9 is to achieve limit, preventing the engraving assembly 6 from moving too far to the left or too far to the right and detaching from the fixed plate 5. Generally, the limit distance is half the length of the connecting shaft 8, that is, the engraving tool 71 on the right can reach the middle position, or move to the right, but cannot move to the left. The above solution can realize the left and right movement of the engraving assembly 6.

[0034] Preferably, the frame 1 is provided with a plurality of bilaterally symmetrical clamping portions 13, and the base 2 is provided with a clamping block 21 connected to the clamping portions 13.

Preferably, the telescopic rod 24 is provided with 2-5 adjustment devices 25, and the adjustment devices 25 are composed of butterfly bolts. The specific clamping method of the base 2 is to place the relief body on the extension clamping device 23 through mechanical operation, and then adjust the telescopic rod 24 through the adjustment device 25 so that the ends of the telescopic rod 24 are supported on the surface of the relief body, and then fixed by the adjustment device 25, and the relief body is supported and fixed by the fixing members 27 of the relief fixing portion 26 to prevent instability due to shaking. It is convenient and flexible to use.

[0036] Preferably, a turntable 28 is provided under the relief support platform 22. The turntable 28 can be used to rotate the relief body and realize carving in multiple directions.

[0037] The method of use of the present invention is:

[0038] When the reliefs to be carved on the left and right are exactly the same, the relief is placed on the base 2 by mechanical means, and after the size is determined by extending the telescopic rod 24 of the clamping device 23, the relief body is fixed on the base 2, and then the rotation speed and direction of the left and right bases 2 are set to be completely consistent. Then the lifting bracket 3 is used to move forward and backward to realize the forward and backward movement of the carving device 4, and the fixed plate 5 of the carving device 4 is used to move up and down to realize the up and down movement of the carving component 6, and the left and right movement of the connecting shaft 8 is used to realize the left and right movement of the carving head 7, thereby realizing the three-dimensional movement of the carving head 7, and realizing carving at any position, to simultaneously carve the relief body on the left and right. After carving a certain position, the turntable 28 on the left and right bases 2 will rotate synchronously to realize carving at other positions, thereby realizing the carving of the relief. When different carving products need to be adjusted, such as when a round carving or a square carving needs to be replaced, or when a large or small relief body needs to be replaced, as Figure 7 As shown, the engraving tool 71 can be driven to rotate downward by the rotary motor 73 to achieve engraving on the relief surface and the relief top, which is convenient and fast.

[0039] When the left and right sides of the engraving are mirror images of each other, the relief is mechanically placed on the base 2. After the size is determined by extending and retracting the telescopic rod 24 of the clamping device 23, the relief body is fixed to the base 2. The left and right bases 2 are then set to rotate at the same speed but in opposite directions. The other engraving steps are the same as the above method.

[0040] The present invention fixes the relief through the base 2, utilizes the front-rear movement of the lifting bracket 3 to realize the front-rear movement of the engraving device 4, utilizes the lifting and lowering movement of the fixing plate 5 of the engraving device 4 to realize the up and down movement of the engraving component 6, utilizes the left and right movement of the connecting shaft 8 to realize the left and right movement of the engraving head 7, thereby realizing the three-dimensional movement of the engraving head 7 and realizing engraving at any position. The engraving accuracy is high, two reliefs on the left and right can be engraved at the same time, the engraving efficiency is high, and the engraving functions are diverse, and it takes up little space.
