DETAILED DESCRIPTION

[0027] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1 to 8 As shown, the technical solution adopted in this specific embodiment is: a stone cutting machine, including a base plate 1, a cutting body 2 arranged on the base plate 1 for cutting the plate, a sliding device arranged on the base plate 1 for allowing the base plate 1 to move horizontally on the stone plate when the cutting body 2 cuts the plate, a guide plate 3 arranged on the base plate 1 for abutting against the side of the stone plate when the base plate 1 moves horizontally on the stone plate to guide the moving direction of the base plate 1, an adjusting member arranged between the guide plate 3 and the base plate 1 for adjusting the distance between the guide plate 3 and the base plate 1 and fixing the guide plate 3 after adjustment, an adjusting plate 4 is provided at the lower end of the base plate 1, and the cutting body 2 is provided on the adjusting plate 4.

[0029] The sliding device includes at least three placement grooves 5 formed on the lower end surface of the base plate 1, and balls 6 disposed on the base plate 1 and located in the placement grooves 5. The placement grooves 5 can also be arc-shaped grooves, which are two-thirds of a full circle. When the balls 6 are installed in the placement grooves 5, the arc-shaped grooves limit the position of the balls 6 and prevent the balls 6 from being disengaged from the placement grooves 5.

[0030] The lower end surface of the bottom plate 1 is located outside the ball 6 and is provided with a limiting annular protrusion 7 for preventing the ball 6 from escaping from the placement groove 5. A gap opening 8 is opened on the limiting annular protrusion 7.

[0031] The bottom surface of the base plate 1 is provided with at least two mounting holes 9, and the adjustment plate 4 is provided with at least two connection ports 10. A mounting bolt 11 is threadedly connected to the bottom surface of the base plate 1 within the mounting holes 9. The screw portion of the mounting bolt 11 is located within the connection port 10. The adjustment plate 4 is provided with a countersunk slot 12 at the end of the mounting hole 9, and the head of the mounting bolt 11 is located within the countersunk slot 12. The mounting bolt 11 is a hexagon socket head bolt.

[0032] The lower end surface of the bottom plate 1 is provided with an escape groove 13 , each of the lower end surfaces of the bottom plate 1 is located in the escape groove 13 , and the adjustment plate 4 is located in the escape groove 13 .

[0033] There are four mounting holes 9 and eight connection ports 10, each of which is located at the front and rear ends of the adjustment plate 4. By changing the connection between the front or rear end of the adjustment plate 4 and the lower end of the base plate 1, the direction of the cutting head 2 can be changed. After the angle adjustment member adjusts the pitch angle of the cutting body 2, a different cutting angle can be formed. For example, when the head is facing forward and the angle adjustment member adjusts the pitch angle of the cutting body 2 to 45°, the cutting surface after cutting will be 45° from front to back. If the cutting surface needs to be 45° from back to front, the head can be turned backward, and the cutting surface after cutting will be 45° from back to front.

[0034] A left connecting plate 14 and a right connecting plate 15 are symmetrically provided at the left and right ends of the adjustment plate 4. A connecting frame 16 is hingedly provided on the left connecting plate 14. The left end of the cutting body 2 is hingedly provided on the connecting frame 16. An angle adjustment piece for adjusting the pitch angle of the cutting body 2 is provided between the left connecting plate 14 and the connecting frame 16. An arc-shaped plate 17 is provided on the right connecting plate 15. An arc-shaped waist hole 18 is opened on the arc-shaped plate 17. The lower end of the arc-shaped plate 17 is hingedly connected to the right connecting plate 15. A plug rod 19 is provided at the right end of the cutting body 2. The plug rod 19 is located in the arc-shaped waist hole 18. The plug rod 19 is clearance-fitted with the arc-shaped waist hole 18. A fixing nut 20 is threadedly connected to the plug rod 19 at the rear side of the arc plate 17. A rotating lever 21 is sleeved on the fixing nut 20 for facilitating hand control of the rotation of the fixing nut 20.

[0035] The lower end of the curved plate 17 is hingedly connected to the right connecting plate 15 via a rotating shaft or a latch. This allows the curved plate 17 to rotate with the angle of the cutting body 2 when adjusting the pitch angle of the cutting body 2, thereby not affecting the angle adjustment operation of the cutting body 2. The left end of the cutting body 2 is hingedly connected to the connecting frame 16 via a rotating shaft or a latch.

[0036] The angle adjustment member includes an arc-shaped sliding opening 22 formed on the left connecting plate 14, an adjustment screw 23 having one end disposed on the connecting frame 16 within the arc-shaped sliding opening 22 and the other end extending through the arc-shaped sliding opening 22 and located on one side of the left connecting plate 14, and an adjustment nut 24 threadedly connected to the other end of the adjustment screw 23 for securing or detaching the connecting frame 16 from the left connecting plate 14. A gasket may be disposed on the end surface of the adjustment screw 23 that is closest to the left connecting plate 14, between the left connecting plate 14 and the adjustment nut 24.

[0037] The adjustment member includes two adjustment blocks 25, the front ends of which are mounted on the base plate 1 and the rear ends of which are connected to the guide plate 3. The two adjustment plates 4 are symmetrically mounted on the upper end surface of the base plate 1. The base plate 1 is provided with an adjustment deep hole 26 at the end of the two adjustment plates 4. Adjustment waist holes 27 are also provided through the two adjustment plates 4. An adjustment bolt 28 is threadedly connected to the inner portion of the adjustment deep hole 26 on the base plate 1. The screw portion of the adjustment bolt 28 is loosely fitted with the adjustment waist hole 27, and the head of the adjustment bolt 28 is positioned above the adjustment plate 4. The adjustment bolt 28 is a hexagon socket head bolt. A gasket, which can be a rubber gasket or a metal gasket, can be placed on the adjustment bolt 28 above the adjustment plate 4. The hexagon socket head bolt is convenient for direct manual operation. The two adjustment plates 4 and the guide plate 3 can be removably connected by bolts.

[0038] The working principle of the present invention is as follows: when it is necessary to cut a stone slab, the base plate 1 is placed on the upper end surface of the stone slab, and the adjusting bolt 28 is reversely screwed by hand or a tool so that the adjusting block 25 is no longer fixed to the upper end surface of the base plate 1, and then the guide plate 3 is pulled outward to adjust the distance between the guide plate 3 and the base plate 1, thereby controlling the cutting position of the cutting body 2 according to the margin required to be cut of the stone slab, and after the cutting position is confirmed, the cutting body 2 is started and the base plate 1 is pushed to move horizontally on the stone slab, and the guide plate 3 is brought into contact with the side edge of the stone slab to guide the moving direction of the base plate 1, without the need for the hand to continuously and steadily move the cutting body 2 along the cutting line, and the operating technical requirements for the operator are low, which can reduce the difficulty of cutting the margin of the stone slab, and the cutting surface is not likely to deviate from the cutting line during the cutting process;

[0039] When it is necessary to cut the stone slab, the fixing nut 20 is driven to rotate in the opposite direction by pushing the rotating lever 21, so that it no longer presses against the curved plate 17. At this time, the cutting body 2 can be pressed downward to slide downward in the curved waist hole 18 through the insertion rod 19, so that the cutting body 2 moves downward to cut the stone slab. When it is not necessary to cut the stone slab, the cutting body 2 is lifted upward to slide upward in the curved waist hole 18 through the insertion rod 19. Then, the rotating lever 21 is pushed to drive the fixing nut 20 to rotate forward, so that it presses against the curved plate 17 to fix the position of the cutting body 2.

[0040] When the cutting angle needs to be adjusted, the adjusting nut 24 is screwed in the reverse direction by a tool, so that the adjusting screw 23 can slide on the arc-shaped slide 22, and the cutting body 2 on the connecting frame 16 is driven by the adjusting screw 23 to achieve angle adjustment. After the adjustment is completed, the adjusting nut 24 is screwed forward, and the adjusting nut 24 is pressed against the left connecting plate 14, thereby increasing the friction between the adjusting nut 24 and the left connecting plate 14, thereby limiting the sliding of the adjusting screw 23 on the arc-shaped slide 22 to fix the cutting angle of the cutting body 2.
