[0057] like Figure 1-3 The present embodiment provides a stone engraving device, including a motion mechanism 1 and a carving knife 2 arranged on the motion mechanism 1, wherein the motion mechanism 1 is used to change the engraving position of the carving knife 2, so as to engrave a corresponding pattern on the stone, wherein the motion mechanism 1 can adopt an XYZ three-axis motion mechanism such as a linear motor or a robotic arm, and how to realize the control of the motion mechanism 1 is an existing technology known to those skilled in the art and will not be repeated here.

[0058] In addition, the present embodiment provides a stone engraving device further comprising:

[0059] The mounting plate 3 has a certain structural strength and can withstand a certain force, so that the remaining structures are arranged on the mounting plate 3 to achieve integrated modular installation;

[0060] The bearing plate 4 is horizontally arranged on the mounting plate 3 through the mounting frame 31, and is used to carry the stone 10. The stone 10 is located on the upper surface of the bearing plate 4. A plurality of liquid permeable holes 41 are arranged at intervals on the bearing plate 4. The arranged liquid permeable holes 41 can be circular, conical, inverted conical or other structures to achieve rapid leakage of the coolant. The coolant can be liquid such as water;

[0061] The clamping mechanism 5 is arranged above the carrying plate 4 and is used to clamp the stone 10 under the action of a driving force. After the stone 10 is placed on the corresponding position of the carrying plate 4, the clamping mechanism 5 clamps the stone 10 stably through the driving force, thereby fixing the position of the stone 10 to avoid displacement of the stone 10 during the carving process, resulting in carving failure or unqualified carved stone;

[0062] A driving mechanism 6, disposed on the mounting plate 3 and connected to the clamping mechanism 5, for generating the driving force;

[0063] The liquid storage tank 7 has an internal accommodating space, and the internal accommodating space contains coolant. The liquid storage tank 7 is located directly below the supporting plate 4 and is connected to the mounting plate 3 via a lifting mechanism 8. The lifting mechanism 8 is used to adjust the height of the liquid storage tank 7. During the engraving process, the stone 10 is placed in place and clamped by the clamping mechanism 5. Then, the height of the liquid storage tank 7 is raised by the lifting mechanism 8. At this time, the supporting plate 4 and the stone 10 are completely immersed below the coolant level. Then, by controlling the movement of the motion mechanism 1, the carving knife 2 on the motion mechanism 1 is driven to move, and a pattern is engraved on the stone 10.

[0064] More specifically, in this embodiment, since the liquid storage tank 7 will move up and down under the action of the lifting mechanism 8 to change its height, a channel 301 for the liquid storage tank 7 to move is formed between the mounting frame 31 and the mounting plate 3, that is, when the liquid storage tank 7 moves to the highest position, one side wall of the liquid storage tank 7 is located in the channel 301. The mounting frames 3 can be provided in plurality and arranged at intervals to improve the structural strength.

[0065] In a specific embodiment, the mounting plate 3 is configured to include: a vertically arranged L-shaped vertical plate and a horizontally arranged horizontal plate, the horizontal plate is arranged on the top end surface of the L-shaped vertical plate, the lifting mechanism 8 is arranged on the side wall of the L-shaped vertical plate, the liquid storage tank 7 is located in the area formed by the L-shaped vertical plate, and the mounting frame 31 and the driving mechanism 6 are both arranged on the lower surface of the horizontal plate.

[0066] Furthermore, if Figure 1-3 As shown, the clamping mechanism 5 comprises:

[0067] A fixed clamping plate 51, fixedly arranged on the carrying plate 4;

[0068] The movable clamping plate 52 is connected to the power output end of the driving mechanism 6 and is used to move on the upper surface of the bearing plate 4 under the action of the driving force, and cooperate with the fixed clamping plate 51 to fix the stone 10.

[0069] Specifically, in this embodiment, the fixed clamping plate 51 is fixed on the bearing plate 4 in this way, and the position of the fixed clamping plate 51 remains unchanged. At the same time, the movable clamping plate 52 is driven to move only by the driving mechanism 6, and the stone 10 is clamped between the movable clamping plate 52 and the fixed clamping plate 51, which can not only ensure the stability of clamping, but also reduce the complexity of control, and the clamping stability is good. The movable clamping plate 52 is connected to the power output end of the driving mechanism 6 through a vertically arranged plate, and the vertically arranged plate is located above the liquid storage tank 7 and when the liquid storage tank 7 moves to the highest position, the vertically arranged plate is located in the liquid storage tank 7.

[0070] Furthermore, the driving mechanism 6 comprises:

[0071] The first cylinder is fixed on the mounting plate 3 , and the telescopic rod of the first cylinder is connected to the movable clamping plate 52 .

[0072] Specifically, in this embodiment, the first cylinder is horizontally arranged on the mounting plate 3 to generate a horizontal driving force, thereby driving the movable clamping plate 52 to move horizontally back and forth on the upper surface of the bearing plate 4, thereby achieving the clamping cooperation between the movable clamping plate 52 and the fixed clamping plate 51. In order to ensure more uniform force and increase stability, two first cylinders are arranged in parallel.

[0073] Furthermore, if Figure 1-3 As shown, the lifting mechanism 8 includes:

[0074] The second cylinder 81 is fixed on the mounting plate 3;

[0075] The accommodating plate 82 is connected to the telescopic rod of the second cylinder. A limiting groove 821 is provided on the accommodating plate 82 , and the liquid storage tank 7 is located in the limiting groove 821 .

[0076] Specifically, in this embodiment, the second cylinder 81 is vertically arranged on the mounting plate 3 to generate a driving force in the vertical direction, thereby driving the receiving plate 82 to move up and down, so as to achieve the up and down movement of the liquid storage tank 7 placed on the receiving plate 82, and to achieve height adjustment. In order to limit the position of the liquid storage tank 7 and avoid the liquid storage tank 7 from being misplaced, which causes the liquid storage tank 7 to collide with the mounting frame 3 and the driving mechanism 61 during movement, a limiting groove 821 is arranged on the receiving plate 82, so that the bottom end of the liquid storage tank 7 is located in the limiting groove 821, thereby limiting the position of the liquid storage tank 7. In order to ensure more uniform force and increase stability, the second cylinder 81 is arranged as two parallel ones.

[0077] In another embodiment, if Figure 1 , 3 As shown, the stone carving device also includes:

[0078] The limiting block 91 is disposed on the bearing plate 4 and is used to limit the longitudinal displacement of the stone 10 .

[0079] Specifically, since the engraving path of the motion mechanism 1 is pre-set, the motion mechanism 1 will drive the chisel 2 to move according to the determined path. Therefore, it is necessary to ensure that the stone 10 is placed in place each time the stone 10 is placed. Since the fixed splint 51 and the movable splint 52 cooperate with each other, the lateral position of the stone 10 can be effectively limited. Therefore, a limit block 91 is set to limit its longitudinal displacement. When placing the stone 10, the end face of the stone 10 can be brought into contact with the limit block 91, which effectively ensures the accuracy of the position of the stone 10. The shapes of the fixed splint 51, the movable splint 52 and the limit block 91 can be set according to the shape of the stone 10 to ensure that they match each other. The fixed splint 51, the movable splint 52 and the limit block 91 can be installed by bolts to facilitate quick disassembly.

[0080] In another embodiment, if Figure 4 As shown, the stone carving device also includes:

[0081] A support frame 92 having an internal accommodation space, wherein the mounting plate 3 is disposed in the internal accommodation space of the support frame 92;

[0082] An openable and closable material door 93 is provided on the support frame 92 and is used for putting in and taking out stones;

[0083] The shell 94 covers other areas of the outer surface of the support frame 92 except the area where the openable and closable material door 93 is set.

[0084] Specifically, during the engraving process, the chisel 2 will be displaced to a certain extent under the action of the motion mechanism 1. In order to isolate it, avoid external interference during its movement and protect the operator, a support frame 92 is set. The support frame 92 has an internal accommodation space, so that the chisel 2 can move in the internal accommodation space, and the mounting plate 3, the bearing plate 4, the mounting frame 31, the clamping mechanism 5, the driving mechanism 6 and the liquid storage tank 7 are all arranged in the internal accommodation space; at the same time, in order to facilitate the placement of the stone 10 and the removal of the engraved stone 10, an openable and closable material door 93 is arranged on the support frame 92, and a shell 94 is arranged on the other areas of the outer surface of the support frame 92 except the area where the openable and closable material door 93 is set to cover it. More specifically, the openable and closable material door 93 and the shell 94 are both made of transparent plastic, such as acrylic plate.

[0085] In another embodiment, if Figure 4 As shown, the stone carving device also includes:

[0086] A plurality of rollers 95 are symmetrically arranged at the bottom end of the support frame 92. In order to facilitate the movement of the entire device, a plurality of rollers 95 are symmetrically arranged at the bottom end of the support frame 92 for movement. After the rollers 95 are moved into place, the position can be fixed by engaging the rollers 95.

[0087] In another embodiment, if Figure 1 As shown, the stone carving device also includes:

[0088] A liquid level sensor 96 is disposed in the liquid storage tank 7 and is used to detect the liquid level in the liquid storage tank 7;

[0089] An alarm is connected to the liquid level sensor 96 and is used to generate an alarm when the liquid level is lower than a set threshold.

[0090] Specifically, in the actual engraving process, a certain amount of coolant is placed in the liquid storage tank 7 to ensure that the stone 10 can be completely immersed in the coolant after the liquid storage tank 7 is moved to a specified height. However, due to the evaporation of the coolant and the loss of the coolant when the stone 10 is taken out after the engraving is completed, the coolant will be reduced in the long run. When the liquid storage tank 7 is moved to a specified height, the coolant cannot completely immerse the stone 10, which will lead to the problem of being unable to cool down and remove dust during the engraving process. Therefore, a liquid level sensor 96 is set in the liquid storage tank 7. When the liquid level is lower than the set threshold, an alarm is generated through an alarm to remind the user to add coolant in time. The alarm can be an audible and visual alarm.

[0091] In another embodiment, the liquid level sensor 96 is disposed in the liquid storage tank 7 via a height adjustment bracket.

[0092] The optional implementation modes of the embodiments of the utility model are described in detail above in conjunction with the accompanying drawings. However, the embodiments of the utility model are not limited to the specific details in the above implementation modes. Within the technical concept of the embodiments of the utility model, the technical scheme of the embodiments of the utility model can be subjected to various simple modifications, and these simple modifications all belong to the protection scope of the embodiments of the utility model.

[0093] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the embodiments of the utility model will not further describe various possible combinations.

[0094] In addition, various implementations of the embodiments of the present utility model can also be arbitrarily combined, as long as they do not violate the concept of the embodiments of the present utility model, they should also be regarded as the contents disclosed in the embodiments of the present utility model.
