Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, the precise cutting and positioning device of the CNC sawing machine comprises a base 1 and a clamping mechanism arranged above the base 1, wherein the clamping mechanism comprises a transmission assembly and a clamping assembly;

[0025] The transmission assembly includes a cylinder 2, the output end of the cylinder 2 is fixedly connected to a lifting plate 3, and the surface of the lifting plate 3 is fixedly connected to a connecting column 4;

[0026] The clamping assembly includes a first clamping column 5, the inner wall of the connecting column 4 is rotatably connected to the first clamping column 5, the interior of the first clamping column 5 is slidably connected to a fixed column 6, one end of the sliding column 6 is fixedly connected to a shell 7, the interior of the shell 7 is fixedly connected to a spring 9, one end of the spring 9 is fixedly connected to a connecting rod 8, and one end of the connecting rod 8 is fixedly connected to a second clamping column 10.

[0027] Among them, Figure 2 As shown, the first clamping column 5 forms a clamping structure through the fixed column 6, the connecting column 4, the lifting plate 3, the cylinder 2 and the outer shell 7, which is conducive to the cylinder 2 driving the lifting plate 3 to move up and down, so that the connecting column 4 can be moved up and down, so that the first clamping column 5 can rotate through the fixed column 6 to clamp the workpiece.

[0028] Among them, Figure 2 As shown, the second clamping column 10 forms a rotating structure with the shell 7 through the spring 9, the connecting rod 8 and the lifting plate 3, which is beneficial for the lifting plate 3 to apply an upward force to the connecting rod 8 during the lifting operation, thereby compressing the spring 9, and then driving the second clamping column 10 to rotate, canceling the clamping of the workpiece so that the workpiece can be picked up.

[0029] Among them, Figure 2 As shown, the first clamping column 5 has a sliding groove inside that matches the fixed column 6, which is beneficial to reduce the friction between the two when the machine is running and increase the service life.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, a fixed block 11 is fixedly connected to the side wall of the base 1, a rotating disk 12 is provided on the surface of the fixed block 11, one end of the rotating disk 12 is fixedly connected to a rotating slide rod 13, an end of the rotating slide rod 13 away from the rotating disk 12 is fixedly connected to a threaded column 14, an outer wall of the threaded column 14 is threadedly connected to a gear 15, and a sliding plate 16 is meshed on the surface of the gear 15.

[0032] Among them, Figure 3 As shown, the top of the rotating slide rod 13 is fixedly connected to one end of the threaded column 14, and a sliding groove that matches the top of the rotating slide rod 13 is provided inside the base 1, which is conducive to driving the rotating slide rod 13 to rotate when the rotating disk 12 rotates. Because a sliding groove that matches the top of the rotating slide rod 13 is provided inside the base 1, when the rotating disk 12 drives the rotating slide rod 13 to rotate, the top of the rotating slide rod 13 will slide in the base 1, thereby causing the threaded column 14 to rotate in the base 1 thread, thereby realizing the operation of rotating the gear 15.

[0033] Among them, Figure 3 As shown, the sliding plate 16 forms a sliding structure with the base 1 through the gear 15 and the threaded column 14, which is beneficial to the rotation of the gear 15. The sliding plate 16 will slide on the base 1 synchronously through the rack meshing with the gear 15, so that the clamping device can be moved. During processing, the position of the workpiece can be adjusted, making the processing more convenient and improving work efficiency. The practicality and applicability can meet market demand.

[0034] When in use: First, when the workpiece needs to be clamped, the cylinder 2 drives the lifting plate 3 to perform lifting operations, and then the connecting column 4 on the lifting plate 3 will also be lifted and lowered. When the connecting column 4 is lifted and lowered, the first clamping column 5 will be rotated through the fixed column 6. At the same time, the lifting plate 3 will also apply an upward force to the connecting rod 8, thereby compressing the spring, and then driving the second clamping column 10 to rotate. At this time, the workpiece is placed on the surface of the outer shell 7, and then the cylinder 2 drives the lifting plate 3 to lift and lower, so that the first clamping column 5 and the second clamping column 10 clamp the workpiece. During processing, the stability of the workpiece can be guaranteed, the workpiece can be fixed more tightly, and it will not shake easily, thereby improving the processing accuracy.

[0035] Finally, through the motor inside the fixed block 10, the motor drives the rotating disk 12 to rotate. When the rotating disk 12 rotates, it will drive the rotating slide rod 13 to rotate, so that the top end of the rotating slide rod 13 slides inside the base 1, driving the threaded column 14 to perform threaded rotation in the base 1, so that the gear 15 will rotate with the threaded column 14, and then the sliding plate 16 meshing with the gear 15 will slide on the base 1 as the gear 15 rotates, so that the clamping device can be moved. During processing, the position of the workpiece can be adjusted, making processing more convenient and improving work efficiency. Both practicality and applicability can meet market demand.
