[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0022] Please refer to Figure 1 , in the embodiment of the present invention, a stone distance-cutting device includes a box-type cutting table 1. Vertical plates 2 are longitudinally slidably inserted through the upper parts on both sides of the box-type cutting table 1. A cutter 3 is rotatably arranged between the two vertical plates 2. And a cutting motor 4 for driving the cutter 3 to rotate is installed on one side of one of the vertical plates 2. A distance adjustment device 5 is arranged between the two vertical plates 2 above the cutter 3.

[0023] Please refer to Figure 2 , in the embodiment of the present invention, the distance adjustment device 5 includes two guide shafts 51 arranged between the two vertical plates 2. A fixed limit block 52 is fixedly sleeved between the outer ends of the two guide shafts 51. And a plurality of moving limit blocks 53 are equidistantly and horizontally slidably sleeved between the outer parts of the two guide shafts 51 on one side of the fixed limit block 52. A rhombic telescopic frame 54 is arranged between the upper parts of the fixed limit block 52 and the moving limit blocks 53. The distance adjustment device 5 further includes a limit seat 55 arranged on the upper side of the vertical plate 2. A servo motor 56 is installed on one side of the limit seat 55. The output shaft of the servo motor 56 is connected with a screw 57. A limit sleeve 58 is screwed onto the outer part of the screw 57. The lower side of the limit sleeve 58 is connected to the upper part of the moving limit block 53 that is the farthest from the fixed limit block 52.

[0024] Please refer to Figure 2, in the embodiment of the present utility model, both ends of the rhombic telescopic frame 54 are respectively hinged to the upper part of the fixed limit block 52 and the upper part of a moving limit block 53 farthest from the fixed limit block 52, and the hinge points at the cross part in the middle of the rhombic telescopic frame 54 are successively hinged to each moving limit block 53. When the rhombic telescopic frame 54 expands and contracts, it will drive each moving limit block 53 to move, thereby realizing the operation of fixed-distance adjustment.

[0025] Please refer to Figure 3 , in the embodiment of the present utility model, the cutting device 3 includes a limit shaft 31 connected to the output shaft of the cutting motor 4. A plurality of cutting blades 32 are slidably sleeved on the outside of the limit shaft 31 at equal intervals. The number of the cutting blades 32 is equal to the sum of the numbers of the fixed limit blocks 52 and the moving limit blocks 53. Concave limit blocks 33 are slidably sleeved on the upper sides of the respective cutting blades 32, and the upper sides of the respective concave limit blocks 33 are successively fixedly arranged at the lower parts of the fixed limit blocks 52 and the respective moving limit blocks 53.

[0026] In the above solution: the servo motor 56 drives the screw rod 57 to rotate, the screw rod 57 will drive the limit sleeve 58 to move, the limit sleeve 58 will drive the moving limit block 53 connected thereto to move. Under the expansion and contraction of the rhombic telescopic frame 54, this moving limit block 53 will drive the remaining moving limit blocks 53 to move. Since the distances between all the intersecting hinge points of the rhombic telescopic frame 54 are equal when it expands and contracts, the distances between the respective moving limit blocks 53 are equal when the respective moving limit blocks 53 move. When the moving limit block 53 moves, the concave limit block 33 at the bottom of the moving limit block 53 will push the cutting blade 32 to displace horizontally on the limit shaft 31, so as to be able to adjust the distance between the respective cutting blades 32, and the distances between the respective cutting blades 32 are equal. After adjusting the distance between the respective cutting blades 32 to a suitable position as required, it is okay.

[0027] Please refer to Figure 4 , in the embodiment of the present utility model, two ball bearings 331 are rotatably embedded on both inner sides of the concave limit block 33. The distance between the two ball bearings 331 is equal to the thickness of the cutting blade 32, and the two ball bearings 331 are respectively in contact with the two surfaces of the cutting blade 32. When the cutting blade 32 rotates, the ball bearings 331 will roll on the cutting blade 32, replacing sliding friction with rolling friction to reduce the wear of the cutting blade 32.

[0028] Please refer to Figure 3, in the embodiment of the present utility model, a rib 34 is provided on one side of the limit shaft 31, and a clamping groove 35 corresponding to the rib 34 is provided on the inner ring side wall of each cutting knife 32. The rib 34 slides through the clamping grooves 35 on each cutting knife 32. The cutting motor 4 drives the limit shaft 31 to rotate. Since the clamping groove 35 on the cutting knife 32 is stuck in the rib 34 on the limit shaft 31, when the limit shaft 31 rotates, the rib 34 will cause each cutting knife 32 to rotate, and the cutting knife 32 will perform the cutting work on the stone material.

[0029] Please refer to Figure 5 , in the embodiment of the present utility model, a hydraulic cylinder 101 is installed on the lower side inside the box-type cutting table 1. A connecting beam 21 is provided between the lower sides of the two vertical plates 2. The output shaft of the hydraulic cylinder 101 is connected to the lower side of the connecting beam 21. The hydraulic cylinder 101 drives the connecting beam 21 to move downward, and the two ends of the connecting beam 21 drive the two vertical plates 2 to move downward respectively, so that the cutting knife 32 moves to the position of the stone material, facilitating the cutting operation on the stone material.

[0030] The working principle corresponding to the above structure is: Place the stone material to be cut on the box-type cutting table 1, and then the servo motor 56 drives the screw rod 57 to rotate. The screw rod 57 will drive the limit sleeve 58 to move, and the limit sleeve 58 will drive the moving limit block 53 connected thereto to move. Under the expansion and contraction of the diamond expansion frame 54, this moving limit block 53 will drive the remaining moving limit blocks 53 to move. And because when the diamond expansion frame 54 expands and contracts, the distances between all the intersecting hinge points are equal, so when each moving limit block 53 moves, the distances between each moving limit block 53 are equal. When the moving limit block 53 moves, the concave limit block 33 at the bottom of the moving limit block 53 will push the cutting knife 32 to move horizontally on the limit shaft 31, so as to be able to adjust the distance between each cutting knife 32, and the distances between each cutting knife 32 are equal. After adjusting the distance between each cutting knife 32 to a suitable position according to the need, it is okay;

[0031] Then the hydraulic cylinder 101 drives the connecting beam 21 to move downward, and the two ends of the connecting beam 21 drive the two vertical plates 2 to move downward respectively, so that the cutting knife 32 moves to the position of the stone material. After that, the cutting motor 4 drives the limit shaft 31 to rotate. Since the clamping groove 35 on the cutting knife 32 is stuck in the rib 34 on the limit shaft 31, when the limit shaft 31 rotates, the rib 34 will cause each cutting knife 32 to rotate, and the cutting knife 32 will perform the cutting work on the stone material.

[0032] At the same time, the content not described in detail in this specification belongs to the well-known prior art in the art.
