[0025] Specifically, before sawing the metal parts, they need to be clamped and fixed. The metal parts are placed between the front clamping head 14 and the rear clamping head 15. The first reversible motor 26 is started, and the first reversible motor 26 drives the gear 7 to rotate forward through the drive shaft 27. The gear 7 drives the U-shaped external rack 5 to move backward, and at the same time, the gear 7 drives the U-shaped internal rack 8 to move forward. The front clamping head 14 and the rear clamping head 15 clamp and fix the metal parts placed on the processing table 2. After the sawing is completed, the metal parts need to be released. At this time, the first reversible motor 26 drives the gear 7 to rotate in the opposite direction through the drive shaft 27. The gear 7 drives the U-shaped external rack 5 to move forward, and at the same time, the gear 7 drives the U-shaped internal rack 8 to move backward. The processed metal parts can be taken out from between the front clamping head 14 and the rear clamping head 15.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The Y-axis guide rail 19 is fixedly connected to the upper surface of the fixed base plate 1.

The side surfaces of the Y-axis slider 18, Z-axis slider 10 and X-axis slider 23 are all fixedly connected to limit rods 13. The limit rods 13 slide within the limit grooves 12.

[0027] Specifically, during the sawing process of metal parts, the second reversible motor 20 of the Y-axis guide rail 19 drives the Y-axis slider 18 to move along the Y-axis via the Y-axis lead screw 17, thereby changing the Y-axis orientation of the sawing machine 22. The third reversible motor 31 of the Z-axis guide rail 16 drives the Z-axis slider 10 to move along the Z-axis via the Z-axis lead screw 11, thereby changing the Z-axis orientation of the sawing machine 22. The fourth reversible motor 28 of the X-axis guide rail 9 drives the X-axis slider 23 to move along the X-axis via the X-axis lead screw 29, thereby changing the X-axis orientation of the sawing machine 22. The sawing machine 22 then saws the metal parts.

[0028] Working principle: The metal parts are sawed using a metal parts processing saw. The metal parts are placed between the front clamping head 14 and the rear clamping head 15. The first reversible motor 26 is started, which drives the gear 7 to rotate forward through the drive shaft 27. The gear 7 drives the U-shaped external rack 5 and the U-shaped internal rack 8 to move, and the metal parts are clamped and fixed between the front clamping head 14 and the rear clamping head 15. The X-axis guide rail 9, Y-axis guide rail 19 and Z-axis guide rail 16 change the position of the sawing machine 22, and the sawing machine 22 cuts the metal parts. After sawing, the first reversible motor 26 drives the gear 7 to rotate in the reverse direction through the drive shaft 27. The gear 7 drives the U-shaped external rack 5 and the U-shaped internal rack 8 to move, so that the U-shaped external rack 5 and the U-shaped internal rack 8 release the clamping and fixing of the metal parts, making it easy to take out the processed metal parts.
