The existing stone trimming machine is mainly a simple trimming machine, which is composed of a workbench, a cutting mechanism, and a clamping mechanism. The existing stone trimming machine has a single function and can only cut one side of the stone. When it is necessary to cut the other sides of the stone, it is necessary to control the clamping mechanism to loosen, then adjust the stone, and then control the clamping mechanism to clamp the stone, so as to cut the four sides of the stone. This method is more troublesome, time-consuming and labor-intensive, and reduces the efficiency of stone trimming.

[0003] Therefore, a CNC edge trimming machine for stone is proposed. Summary of the invention

[0006] When working, the existing stone trimming machine has a single function and can only cut one side of the stone. When it is necessary to cut the other sides of the stone, it is necessary to control the clamping mechanism to loosen, then adjust the stone, and then control the clamping mechanism to clamp the stone to cut the four sides of the stone. This method is relatively troublesome, time-consuming and labor-intensive, and reduces the efficiency of stone trimming. When the present invention is used, first, the first motor is connected to the external power supply, and the first motor is driven to rotate, and the screw rod fixedly connected to the first motor rotates accordingly. Since the ball seat is rolled on the outer surface of the screw rod, the ball seat can move along the screw rod, and the saw blade connected to the ball seat through the rotating mechanism moves accordingly, so that the stone can be trimmed. By setting the clamping mechanism, not only can the stone be clamped, but also the stone can be rotated, so that the saw blade can cut the four sides of the stone, without clamping the stone multiple times, saving manpower and improving the efficiency of stone trimming.

[0007] Preferably, the clamping mechanism includes a first cylinder, a rotating column, a first hydraulic rod, a fixed seat, an upper fixed plate, a lower fixed plate, a second cylinder, a second motor, a first gear, a second gear, a slide groove, a slide seat, a slider, a second hydraulic rod and a through groove. A through groove is provided in the middle of the upper surface of the bottom plate and the L-shaped plate, a second hydraulic rod is embedded in the inside of the bottom plate and the inside of the L-shaped plate, one end of the second hydraulic rod is fixedly connected to the slide seat, a slide seat is slidably installed in the through groove, sliders are symmetrically fixedly connected to the outer surface of the slide seat on both sides, slide grooves are symmetrically provided on the inner surface of the through groove, and the slider is inside the slide groove and slidably cooperates with the slide groove, and the first cylinder is fixedly connected to the middle of the lower surface of the slide seat located above The cam is secured to the bottom of the chassis and is provided with a plurality of camshafts, each of which is secured with a plurality of camshafts, each of which is secured with a plurality of camshafts. The camshafts are secured to the bottom of the chassis and are provided with a plurality of camshafts. The camshafts are secured to the bottom of the chassis and are provided with a plurality of camshafts.

[0008] During operation, in order to facilitate the trimming of the four sides of the stone, save manpower and improve the trimming efficiency, a clamping mechanism is set, the stone to be cut is placed on the upper surface of the lower fixed plate, and then the first hydraulic rod is driven to extend, and the upper fixed plate fixedly connected to the first hydraulic rod is moved downward, so that the stone can be fixed between the upper fixed plate and the lower fixed plate. After the stone is fixed, the stone can be trimmed. When it is necessary to cut the remaining sides of the stone, the second motor is connected to the external power supply, and the second motor is driven to rotate, and the first gear fixedly connected to the second motor rotates accordingly. Since the first gear is meshed with the second gear, the second gear rotates accordingly, and the lower fixed plate fixedly connected to the second gear through the second cylinder rotates accordingly. Since the rotating column and the first cylinder are in rotational cooperation, the upper fixed plate fixedly connected to the rotating column through the first hydraulic rod and the fixed seat rotates accordingly, and the stone clamped between the upper fixed plate and the lower fixed plate rotates accordingly, so that the stone can be rotated, so that the four sides of the stone can be cut, avoiding multiple adjustments of the clamping mechanism and improving the trimming efficiency.

[0009] Preferably, the rotating mechanism comprises a vertical plate, a fixed block, a rotating shaft, a connecting block, a fixing bolt, a connecting pipe, a third gear, a third motor and a fourth gear, the outer surface of the ball seat is symmetrically fixedly connected with the fixed block, a rotating shaft is rotatably installed between the two fixed blocks, a connecting block is rotatably sleeved on the middle position of the outer surface of the rotating shaft, a fixing bolt is threadedly inserted at the middle position of one side of the outer surface of the connecting block, and the fixing bolt passes through the connecting block and presses against the rotating shaft, the outer surface of the connecting block is fixedly connected with the vertical plate on one side away from the direction of the ball seat, the outer surface of the vertical plate is fixedly connected with the connecting pipe on one side away from the direction of the connecting block, the outer surface of the connecting pipe is rotatably sleeved with the third gear, the outer surface of the third gear is fixedly connected with a saw blade at the middle position of the side away from the direction of the vertical plate, and the third gear passes through the connecting pipe and rotatably cooperates with it, the outer surface of the vertical plate is fixedly connected to the third motor at a position away from the connecting pipe, the output end of the third motor is fixedly connected to the fourth gear, and the fourth gear meshes with the third gear.

[0010] During work, in the process of processing stone, sometimes it is necessary to cut square stone into circle. The angle of the existing cutting blade cannot be adjusted and processing cannot be performed. By setting a rotating mechanism, after the stone to be cut is clamped, the fixing bolt is loosened, and the connecting block is controlled to rotate around the rotating axis. The vertical plate fixedly connected to the connecting block rotates accordingly, so that the angle of the saw blade can be adjusted so that the direction of the saw blade is toward the tangent direction of the circular stone. Then the fixing bolt is tightened to fix the connecting block, and the third motor is connected to an external power supply, and the third motor is driven to rotate, so that the fourth gear fixedly connected to the third motor rotates. Since the fourth gear is meshed with the third gear, the third gear rotates accordingly, and the saw blade fixedly connected to the third gear rotates accordingly, so that the stone can be cut.

[0011] Preferably, the lower surface of the ball seat is fixedly connected to a water tank, a hose is fixedly connected to one side of the outer surface of the water tank, and a pump is fixedly connected to the outer surface of the water tank near the hose, the pump is connected to the hose, one end of the hose away from the water tank is fixedly connected to a connecting pipe, and a bent pipe is fixedly connected to one side of the outer surface of the connecting pipe away from the hose, and the lower end of the bent pipe faces the saw blade.

[0012] During operation, the temperature of the saw blade is high when cutting edges, and cooling water is needed to cool it. By setting up a water tank, the water in the water tank is pumped out by a pump, and the cooling water is sprayed out from the elbow through a hose and a connecting pipe. The cooling water is sprayed on the surface of the saw blade, thereby cooling the saw blade and preventing damage to the saw blade.

[0013] Preferably, a protective box is fixedly connected to the upper surface of the base plate at the edge of the through groove, a square groove is opened in the middle of the upper surface of the protective box, a protective plate is slidably installed inside the square groove, and the middle position of the protective plate is fixedly connected to the second cylinder.

[0014] During operation, the sprayed cooling water carries the dust generated by cutting and falls to the upper surface of the bottom plate, which is easy to slide into the through groove, causing the slide seat to slide unsmoothly. By setting up a protective box, the cooling water can be prevented from sliding into the through groove. By setting up a protective plate, the protective box can be kept closed while the second cylinder moves.

[0015] Preferably, the positioning mechanism includes an L-shaped rod, a round hole, a positioning block, a spring, a vertical rod, a positioning pen and a latch, the L-shaped rod is slidably inserted into the bottom of the first cylinder, and the upper surface of the L-shaped rod is provided with equidistantly distributed round holes, a latch is inserted into the outer surface of the first cylinder, and the latch is inserted into one of the round holes, the lower surface of the L-shaped rod is fixedly connected to the positioning block, a vertical rod is slidably installed in the middle position of the lower surface of the positioning block, the lower surface of the vertical rod is fixedly connected to the positioning pen, the outer surface of the vertical rod is covered with a spring, the upper end of the spring is fixedly connected to the positioning block, and the lower end of the spring is fixedly connected to the positioning pen.

[0016] During work, when cutting a square stone into a circle, the size of the circle to be cut may be different, and it is necessary to mark the surface of the stone. By setting a positioning mechanism, by setting a round hole and a pin, and by moving the L-shaped rod, the radius of the marked circle can be adjusted. After adjusting the appropriate radius, the pin is inserted into the corresponding round hole. By setting a positioning block and other structures, first, the vertical rod is moved upward, and the spring is squeezed and compressed. After the stone is placed, the vertical rod is released, the spring extends, and the positioning pen is pushed down, so that the positioning pen contacts the upper surface of the stone. When the stone rotates, the positioning pen can mark the surface of the stone.

[0017] Preferably, an arc groove is opened in the middle position of the lower surface of the upper fixed plate and the middle position of the upper surface of the lower fixed plate, arc plates are embedded on both sides of the inner surface of the arc groove, third hydraulic rods are embedded on both sides of the lower fixed plate, and the third hydraulic rod is fixedly connected to the arc plate.

[0018] During operation, when cutting cylindrical stones, it is inconvenient to clamp them. By setting structures such as arc grooves, when cutting cylindrical stones, the stones are placed inside the arc grooves, and the arc plate is driven to move by driving the third hydraulic rod to extend, so that the cylindrical stones can be clamped and cut easily.

[0019] Preferably, both sides of the lower surface of the upper fixing plate and both sides of the upper surface of the lower fixing plate are fixedly connected with anti-slip pads.

[0020] During operation, since the surface of the stone is relatively smooth, the stone may slide relative to the upper fixed plate and the lower fixed plate, resulting in inaccurate cutting edges. By fixing anti-slip pads on both sides of the lower surface of the upper fixed plate and both sides of the upper surface of the lower fixed plate, the friction between the stone and the upper fixed plate and the lower fixed plate can be increased, preventing the stone from sliding relative to the upper fixed plate and the lower fixed plate, resulting in inaccurate cutting edges.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can not only clamp the stone but also rotate the stone by setting a clamping mechanism, so that the saw blade can cut the four sides of the stone without clamping the stone multiple times, thus saving manpower and improving the efficiency of stone cutting.

[0023] 2. The present invention can rotate the stone clamped between the upper fixed plate and the lower fixed plate by driving the second motor to rotate, thereby rotating the stone, thereby cutting the four sides of the stone, avoiding multiple adjustments of the clamping mechanism, and improving the cutting efficiency.

Since the ball seat 6 is rolled and sleeved on the outer surface of the screw rod 5, the ball seat 6 can move along the screw rod 5, and the saw blade 7 connected to the ball seat 6 through the rotating mechanism 9 moves accordingly, so that the stone can be trimmed. By setting the clamping mechanism 8, not only can the stone be clamped, but also the stone can be rotated, so that the saw blade 7 can cut the four sides of the stone, without clamping the stone multiple times, saving manpower and improving the efficiency of stone trimming.

The slides 811 are symmetrically provided on the inner surface of the through slot 815 on both sides. The sliders 813 are slidably matched with the slide 811 inside the slide 811 and are located in the middle of the lower surface of the slide 812 above.

A second cylinder 87 is fixedly connected to the middle position of the upper surface of the second gear 810, and a lower fixed plate 86 is fixedly connected to the upper surface of the second cylinder 87.

[0037] During operation, in order to facilitate the trimming of the four sides of the stone, save manpower and improve the trimming efficiency, the clamping mechanism 8 is set to place the stone to be cut on the upper surface of the lower fixed plate 86, and then the first hydraulic rod 83 is driven to extend, and the upper fixed plate 85 fixedly connected to the first hydraulic rod 83 is moved downward, so that the stone can be fixed between the upper fixed plate 85 and the lower fixed plate 86. After the stone is fixed, the stone can be trimmed. When it is necessary to cut the remaining sides of the stone, the second motor 88 is connected to the external power supply and the second motor 88 is driven to rotate, and the second motor 88 fixedly connected to the second motor 88 is driven to rotate. A gear 89 rotates accordingly, and since the first gear 89 is meshed with the second gear 810, the second gear 810 rotates accordingly, and the lower fixed plate 86 fixedly connected to the second gear 810 via the second cylinder 87 rotates accordingly. Since the rotating column 82 is rotationally matched with the first cylinder 81, the upper fixed plate 85 fixedly connected to the rotating column 82 via the first hydraulic rod 83 and the fixed seat 84 rotates accordingly, and the stone clamped between the upper fixed plate 85 and the lower fixed plate 86 rotates accordingly, so that the stone can be rotated, so that the four sides of the stone can be cut, avoiding multiple adjustments of the clamping mechanism 8 and improving the edge cutting efficiency.

[0038] As an embodiment of the present invention, Figure 3 As shown, the rotating mechanism 9 includes a vertical plate 91, a fixed block 92, a rotating shaft 93, a connecting block 94, a fixing bolt 95, a connecting pipe 96, a third gear 97, a third motor 98 and a fourth gear 99. The outer surface of the ball seat 6 is symmetrically fixedly connected with the fixing block 92, and a rotating shaft 93 is rotatably installed between the two fixing blocks 92. A connecting block 94 is rotatably mounted on the middle position of the outer surface of the rotating shaft 93. A fixing bolt 95 is threadedly inserted in the middle position of one side of the outer surface of the connecting block 94, and the fixing bolt 95 passes through the connecting block 94 and presses against the rotating shaft 93. The outer surface of the connecting block 94 is away from the ball seat. A vertical plate 91 is fixedly connected to one side in the direction of 6, a connecting pipe 96 is fixedly connected to the outer surface of the vertical plate 91 on the side away from the connecting block 94, a third gear 97 is rotatably mounted on the outer surface of the connecting pipe 96, a saw blade 7 is fixedly connected to the middle position of the outer surface of the third gear 97 away from the vertical plate 91, and the third gear 97 penetrates the connecting pipe 96 and rotatably cooperates therewith, a third motor 98 is fixedly connected to the position of the outer surface of the vertical plate 91 away from the connecting pipe 96, a fourth gear 99 is fixedly connected to the output end of the third motor 98, and the fourth gear 99 is meshed with the third gear 97.

[0039] During operation, in the process of processing stone, sometimes it is necessary to cut square stone into a circle. The angle of the existing cutting blade cannot be adjusted and processing cannot be performed. By setting the rotating mechanism 9, after the stone to be trimmed is clamped, the fixing bolt 95 is loosened, and the connecting block 94 is controlled to rotate around the rotating shaft 93, and the vertical plate 91 fixedly connected to the connecting block 94 rotates accordingly, so that the angle of the saw blade 7 can be adjusted so that the direction of the saw blade 7 is toward the tangent direction of the circular stone. Then the fixing bolt 95 is tightened to fix the connecting block 94, and the third motor 98 is connected to the external power supply, and the third motor 98 is driven to rotate, and the fourth gear 99 fixedly connected to the third motor 98 rotates accordingly. Since the fourth gear 99 is meshed with the third gear 97, the third gear 97 rotates accordingly, and the saw blade 7 fixedly connected to the third gear 97 rotates accordingly, so that the stone can be cut.

[0040] As an embodiment of the present invention, Figure 3 As shown, the lower surface of the ball seat 6 is fixedly connected to a water tank 14, and a hose 15 is fixedly connected to one side of the outer surface of the water tank 14, and a pump is fixedly connected to the outer surface of the water tank 14 near the hose 15, and the pump is connected to the hose 15. The end of the hose 15 away from the water tank 14 is fixedly connected to a connecting pipe 96, and the side of the outer surface of the connecting pipe 96 away from the hose 15 is fixedly connected to a bent pipe 16, and the lower end of the bent pipe 16 faces the saw blade 7.

[0041] During operation, the temperature of the saw blade 7 is high during edge cutting, and cooling water is needed to cool it. By setting a water tank 14, the water in the water tank 14 is pumped out by a pump, and the cooling water is sprayed out from the bent pipe 16 through the hose 15 and the connecting pipe 96. The cooling water is sprayed on the surface of the saw blade 7, thereby being able to cool the saw blade 7 and prevent the saw blade 7 from being damaged.

[0042] As an embodiment of the present invention, Figure 2 As shown, a protective box 17 is fixedly connected to the upper surface of the base plate 1 at the edge of the through groove 815, a square groove is opened in the middle of the upper surface of the protective box 17, a protective plate 18 is slidably installed inside the square groove, and the middle position of the protective plate 18 is fixedly connected to the second cylinder 87.

[0043] During operation, the sprayed cooling water carries the dust generated by cutting and falls to the upper surface of the base plate 1, and is easy to slide into the through groove 815, which may cause the slide seat 812 to slide unsmoothly. By setting up a protective box 17, the cooling water can be prevented from sliding into the through groove 815. By setting up a protective plate 18, the protective box 17 can be kept closed while the second cylinder 87 moves.

[0044] As an embodiment of the present invention, Figure 4As shown, the positioning mechanism 10 includes an L-shaped rod 101, a circular hole 102, a positioning block 103, a spring 104, a vertical rod 105, a positioning pen 106 and a latch 107. The L-shaped rod 101 is slidably inserted into the bottom of the first cylinder 81, and the upper surface of the L-shaped rod 101 is provided with equidistantly distributed circular holes 102, the outer surface of the first cylinder 81 is inserted with a latch 107, and the latch 107 is inserted into one of the circular holes 102, the lower surface of the L-shaped rod 101 is fixedly connected with the positioning block 103, the vertical rod 105 is slidably installed in the middle position of the lower surface of the positioning block 103, the lower surface of the vertical rod 105 is fixedly connected with the positioning pen 106, and the outer surface of the vertical rod 105 is covered with a spring 104, the upper end of the spring 104 is fixedly connected to the positioning block 103, and the lower end of the spring 104 is fixedly connected to the positioning pen 106.

[0045] During operation, when cutting a square stone into a circle, the size of the circle to be cut may be different, and it is necessary to mark the surface of the stone. By setting the positioning mechanism 10, by setting the circular hole 102 and the latch 107, and by moving the L-shaped rod 101, the radius of the marked circle can be adjusted. After adjusting the appropriate radius, the latch 107 is inserted into the corresponding circular hole 102. By setting the positioning block 103 and other structures, first, the vertical rod 105 is moved upward, and the spring 104 is squeezed and compressed. After the stone is placed, the vertical rod 105 is released, and the spring 104 extends, pushing the positioning pen 106 downward, so that the positioning pen 106 contacts the upper surface of the stone. When the stone rotates, the positioning pen 106 can mark the surface of the stone.

[0046] As an embodiment of the present invention, Figure 5 As shown, an arc groove 11 is provided in the middle position of the lower surface of the upper fixed plate 85 and the middle position of the upper surface of the lower fixed plate 86, and arc plates 12 are embedded on both sides of the inner surface of the arc groove 11, and third hydraulic rods 13 are embedded on both sides of the lower fixed plate 86, and the third hydraulic rod 13 is fixedly connected to the arc plate 12.

[0047] During operation, when cutting a cylindrical stone, it is inconvenient to clamp it. By setting structures such as the arc groove 11, when cutting the cylindrical stone, the stone is placed inside the arc groove 11, and the arc plate 12 is driven to move by driving the third hydraulic rod 13 to extend, so that the cylindrical stone can be clamped and cut easily.

[0048] As an embodiment of the present invention, Figure 5 As shown, both sides of the lower surface of the upper fixing plate 85 and both sides of the upper surface of the lower fixing plate 86 are fixedly connected with anti-slip pads 19 .

[0049] During operation, since the surface of the stone is relatively smooth, the stone may slide relative to the upper fixing plate 85 and the lower fixing plate 86, resulting in inaccurate cutting edges. By fixing the anti-slip pads 19 on both sides of the lower surface of the upper fixing plate 85 and both sides of the upper surface of the lower fixing plate 86, the friction between the stone and the upper fixing plate 85 and the lower fixing plate 86 can be increased to prevent the stone from sliding relative to the upper fixing plate 85 and the lower fixing plate 86, resulting in inaccurate cutting edges.

[0050] Instructions for use: When the present invention is used, first, the first motor 3 is connected to an external power source, and the first motor 3 is driven to rotate, and the screw rod 5 fixedly connected to the first motor 3 rotates accordingly. Since the ball seat 6 is rolled and sleeved on the outer surface of the screw rod 5, the ball seat 6 can move along the screw rod 5, and the saw blade 7 connected to the ball seat 6 through the rotating mechanism 9 moves accordingly, so that the stone can be trimmed. In order to facilitate the trimming of the four sides of the stone, save manpower, and improve the trimming efficiency, a clamping mechanism 8 is provided to place the stone to be cut on the upper surface of the lower fixed plate 86, and then the first hydraulic rod 83 is driven to extend, and the upper fixed plate 85 fixedly connected to the first hydraulic rod 83 is moved downward, so that the stone can be fixed between the upper fixed plate 85 and the lower fixed plate 86. After the stone is fixed, the stone can be trimmed. During trimming, when the remaining edges of the stone need to be cut, the second motor 88 is connected to an external power source and driven to rotate, and the first gear 89 fixedly connected to the second motor 88 rotates accordingly. Since the first gear 89 is meshed with the second gear 810, the second gear 810 rotates accordingly, and the lower fixed plate 86 fixedly connected to the second gear 810 via the second cylinder 87 rotates accordingly. Since the rotating column 82 is rotationally matched with the first cylinder 81, the upper fixed plate 85 fixedly connected to the rotating column 82 via the first hydraulic rod 83 and the fixed seat 84 rotates accordingly, and the stone clamped between the upper fixed plate 85 and the lower fixed plate 86 rotates accordingly, so that the stone can be rotated, so that the four sides of the stone can be cut, avoiding multiple adjustments of the clamping mechanism 8 and improving the trimming efficiency.
