Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The embodiment of the present utility model provides a stone engraving machine with a flipping mechanism, including an engraving table 1. Exemplarily, as Figures 1-7 shown.

[0029] A slide rail 21 is arranged on the upper side of the engraving table 1. An engraving machine body 22 is arranged on one side of the slide rail 21. A cutter head 23 is arranged on the lower side of the engraving machine body 22. An air cylinder 24 is fixedly connected to the inner side of the engraving table 1. The output end of the air cylinder 24 is in transmission connection with a placing plate 25. A flipping mechanism 3 is arranged inside the engraving table 1.

[0030] The flipping mechanism 3 includes a mounting plate 31 fixedly connected to one side of the placing plate 25. A fixing block 32 is fixedly connected to the upper side of the mounting plate 31. A driving block 33 is also slidably connected to the upper side of the mounting plate 31. Connection components 34 are arranged on the upper sides of both the fixing block 32 and the driving block 33.

[0031] A connecting rod 35 is arranged on the upper side of one of the connection components 34. A flipping plate 37 is arranged on the upper side of the other connection component 34. A rotating rod 36 is rotatably connected to one side of the flipping plate 37. The side of the connecting rod 35 away from the fixing block 32 is rotatably connected to the outer side of the rotating rod 36.

[0032] Specifically, the slide rail 21 can drive the engraving machine body 22 to move, so as to engrave the stone through the cutter head 23, and the air cylinder 24 can push or pull the placement plate 25 through operation, so that the placement plate 25 can adjust the position according to the size of the stone. At the same time, the placement plate 25 can place the stone. When the stone is placed, the placement plate 25 needs to be close to the center of the inner side of the stone, so that the flipping mechanism 3 can be used smoothly;

[0033] In addition, the mounting plate 31 can connect the fixed block 32 and the driving block 33. The fixed block 32 can connect the connecting rod 35 through one of the connecting components 34, and the driving block 33 can connect the flipping plate 37 through the other connecting component 34. When the stone needs to be flipped, the upper side of the flipping plate 37 is located under the stone. When the driving block 33 moves, it will drive the flipping plate 37 to flip around the connecting component 34 through the connecting rod 35, and will be restricted by the connecting rod 35 during flipping, so as to realize the flipping of the flipping plate 37 and the stone.

[0034] The two connecting components 34 include connecting blocks 341 respectively fixedly connected to the upper sides of the fixed block 32 and the driving block 33, as Figures 1-7 shown.

[0035] Rotating blocks 342 are rotatably connected to the inner sides of the two connecting blocks 341, and connecting ring blocks 343 are rotatably connected to the outer sides of the two rotating blocks 342. The outer side of one of the connecting ring blocks 343 is rotatably connected to the connecting rod 35, and the outer side of the other connecting ring block 343 is rotatably connected to the flipping plate 37.

[0036] One side of the placement plate 25 is fixedly connected with a mounting hollow block 61. A lead screw 62 is rotatably connected to the inside of the mounting hollow block 61. One side of the mounting hollow block 61 is fixedly connected with a servo motor 63. One end of the servo motor 63 penetrates the mounting hollow block 61, and the output end of the servo motor 63 is in transmission connection with one end of the lead screw 62 through a coupling. The mounting plate 31 is threadedly connected to the outside of the lead screw 62.

[0037] One side of the mounting plate 31 is fixedly connected with a mounting block 51. One side of the mounting block 51 is fixedly connected with an electric telescopic rod 52. One end of the electric telescopic rod 52 is fixedly connected with a push plate 53, and one side of the push plate 53 is fixedly connected to the driving block 33.

[0038] Specifically, the connecting block 341 can connect the connecting ring block 343 through the rotating block 342, and the two connecting ring blocks 343 are respectively connected to the connecting rod 35 and the flipping plate 37, so as to facilitate the flipping of the flipping plate 37;

[0039] In addition, when the servo motor 63 operates, it will drive the lead screw 62 to rotate, thereby realizing the movement of the mounting plate 31, so that when the flipping mechanism 3 is used for stone carving, it is not easy to affect the normal placement of the stone, and when flipping is required, the flipping plate 37 can be smoothly moved to the lower side of the stone;

[0040] In addition, the electric telescopic rod 52 can drive the push plate 53 and the driving block 33 to move through its own expansion and contraction, thereby realizing the pushing of the driving block 33 and the normal use of the flipping plate 37, making the operation of the flipping mechanism 3 sufficiently convenient.

[0041] A limiting groove 42 is provided on the upper side of the mounting plate 31. A limiting block 41 is fixedly connected to the lower side of the driving block 33, and the limiting block 41 is slidably connected to the inside of the limiting groove 42, as Figures 1-7 shown.

[0042] A slider 102 is provided inside the engraving table 1. A limiting groove 101 is fixedly connected to the lower side of the placing plate 25, and the limiting groove 101 is slidably connected to the inside of the slider 102.

[0043] A rubber layer 7 is provided on the upper side of the flipping plate 37. A bottom block 81 is fixedly connected to the lower side of the engraving table 1. A bottom foot 82 is provided on the lower side of the bottom block 81. An insertion block 83 is fixedly connected to the upper side of the bottom foot 82, and the insertion block 83 is movably inserted into the inside of the bottom block 81. A bolt 9 is provided between the insertion block 83 and the bottom block 81.

[0044] Specifically, the setting of the limiting block 41 and the limiting groove 42 makes it not easy for the driving block 33 to deviate when the electric telescopic rod 52 pushes the driving block 33, increasing the stability of the movement of the driving block 33. The setting of the limiting groove 101 and the slider 102 makes the placing plate 25 move stably enough, and it is not easy for the stone to fall due to deviation or inclination;

[0045] In addition, the bottom block 81 and the bottom foot 82 can form a base. The setting of the insertion block 83 can facilitate the connection and installation of the bottom foot 82. The setting of the bolt 9 makes the bottom foot 82 and the bottom block 81 sufficiently stable after being connected to each other through the insertion block 83.

[0046] A stone engraving machine with a flipping mechanism proposed by an embodiment of the present utility model has the following working principle: When this device is in use, the position of the placement plate 25 can be adjusted according to the size of the stone. During the adjustment, the placement plate 25 is pushed or pulled by the cylinder 24, and the movement of the placement plate 25 will drive the flipping mechanism 3 to move together. The stone can be engraved by the engraving machine body 22. After that, when the stone needs to be flipped, the servo motor 63 can be started, and the rotation of the lead screw 62 is driven by the operation of the servo motor 63, so as to realize the position adjustment of the flipping mechanism 3.

[0047] After that, when the flipping plate 37 moves to the lower side of the stone and its inner side fits the stone, the electric telescopic rod 52 can be started to make the electric telescopic rod 52 push the driving block 33, so that the driving block 33 slides on the upper side of the mounting plate 31. As the driving block 33 moves, the connecting rod 35 serves as the fulcrum of the lever. When the connecting rod 35 moves with the driving block 33, it will drive the rotating rod 36 to rotate, and then make the flipping plate 37 flip around the connecting component 34. During the flipping process of the flipping plate 37, due to the limitation of the connecting rod 35, it will flip smoothly along a predetermined trajectory, thus driving the stone above it to flip together.

[0048] When the driving block 33 moves to the predetermined position, the flipping plate 37 and the stone have also completed the flipping action. After that, the flipping mechanism 3 can be driven to reset through the operation of the servo motor 63. If the stone needs to be flipped again, the flipping mechanism 3 can be reset by the electric telescopic rod 52, and then the above operation can be repeated again.

[0049] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
