[0023] like Figures 1 to 4 As shown, this utility model provides a cutting tool with precise positioning function, including a worktable 1. A cutting device 2 is provided on the upper surface of the worktable 1, including: a power unit providing the power required for cutting; a tool system, the main cutting part; a spindle supporting and rotating the tool and transmitting power to the tool; a moving device to achieve linear movement of the workpiece or tool; and a slide rail for moving the device. A mounting base 3 is fixedly connected to the lower surface of the worktable 1, and a motor 4 is fixedly connected to the outer surface of the mounting base 3. A bidirectional lead screw 5 is fixedly connected to the output end of the motor 4. The threaded connection has two threaded blocks 6 with opposite internal thread directions. A fixing rod 7 is fixedly connected to the upper surface of the threaded block 6. A clamping plate 8 is fixedly connected to the end of the fixing rod 7 away from the threaded block 6. A slide groove 9 is provided on the worktable 1. A slider 10 is slidably connected in the slide groove 9. A positioning plate 11 is fixedly connected to the upper surface of the slider 10. A fixing bolt 12 is provided on the slider 10. A fixing nut 13 is threadedly connected to the fixing bolt 12. The position of the slider 10 is fixed by the clamping force between the fixing bolt 12, the fixing nut 13 and the worktable 1, thereby fixing the positioning plate 11.

[0024] Specifically, the fixing nut 13 is movably connected to the worktable 1. The fixing nut 13 is located below the worktable 1. By locking the fixing bolt 12 into the fixing nut 13, the position of the positioning plate 11 can be fixed.

[0025] Furthermore, a dust collection box 19 is detachably connected to the lower surface of the workbench 1 for collecting powder generated during cutting, and the workbench 1 is provided with a scale 18.

[0026] Furthermore, a support block 16 is movably connected to the upper surface of the workbench 1, and a second telescopic rod 17 is fixedly connected to the outer surface of the support block 16. The other end of the second telescopic rod 17 is fixedly connected to the positioning plate 11 to prevent the threaded block 6 from rotating.

[0027] It is worth noting that a fixing block 14 is fixedly connected to the lower surface of the worktable 1. The fixing block 14 is rotatably connected to the bidirectional lead screw 5 and is used to support the other end of the bidirectional lead screw 5.

[0028] It is worth noting that a first telescopic rod 15 is fixedly connected to the outer surface of the threaded block 6, and the other end of the first telescopic rod 15 is fixedly connected to another threaded block 6.

[0029] It is worth mentioning that the workbench 1 is provided with a slot 20, and the fixed rod 7 is slidably connected to the slot 20.

[0030] It is worth emphasizing that a rubber plate is fixedly connected to the outer surface of the clamping plate 8, and a support leg is fixedly connected to the lower surface of the workbench 1.

[0031] The cutting device 2 and motor 4 are existing technologies and will not be described in detail.

The "front, rear, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: In use, firstly, according to the size to be cut, slide the slider 10 in the groove 9. The slider 10 drives the positioning plate 11 to slide. The position where the positioning plate 11 stops is the cutting size. The two second telescopic rods 17 ensure the linear movement of the positioning plate 11. Then, tighten the fixing bolts 12 and fixing nuts 13. The clamping force between the fixing bolts 12 and fixing nuts 13 and the worktable 1 fixes the position of the slider 10, thereby fixing the positioning plate 11. Then, place the workpiece on the worktable 1 and place one end against the positioning plate 11. Then, the motor 4 on the mounting base 3 drives the double-acting screw 5 to rotate. Through the action of the thread, the two threaded blocks 6 move linearly on the double-acting screw 5. The two threaded blocks 6 move towards each other or opposite each other. Through the opposite movement of the two threaded blocks 6, the fixing rod 7 and the clamping plate 8 slide. The two clamping plates 8 clamp and fix the position of the workpiece. Then, the cutting device 2 performs the cutting work.
