[0017] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] Reference Figure 1-4 This invention proposes an embodiment of a dual-spindle dual-row cutter, including a fixed base 5 on a dual-row cutter assembly 23. The dual-row cutter assembly 23 is disposed above the fixed base 5. Both ends of the top of the fixed base 5 are provided with a moving platform 11 that moves in the horizontal direction through a transmission mechanism. A placement seat 13 is fixedly connected to the upper surface of the moving platform 11. A clamping seat 21 is detachably disposed on the top of the placement seat 13 by a number of bolts 12.

[0019] A receiving groove is provided between the opposite surfaces of the placement seat 13 and the clamping seat 21. The spindle assembly 14 is clamped and fixed inside the receiving groove. The output shafts of the two spindle assemblies 14 are opposite to each other and are provided with a connecting part 16.

[0020] The bottom of the fixed base 5 is fixedly connected to the receiving box 1, and the bottom of the receiving box 1 is provided with a base plate 3 that moves in the vertical direction through a support mechanism.

[0021] After the transmission mechanism is in operation, the distance between the two moving tables 11 can be adjusted, thereby adjusting the distance between the two spindle assemblies 14 to adapt to different processing requirements. When the spindle assembly 14 needs to be inspected and maintained, simply remove the bolts 12 and open the clamping seat 21 to remove the spindle assembly 14 from the inside of the placement seat 13. The operation is simple and quick, making it easy to remove the spindle assembly 14 from the machine tool, and thus facilitating the replacement or inspection and maintenance of the spindle assembly 14.

[0022] Furthermore, the transmission mechanism includes two connecting platforms 6 and a support block 22. The two connecting platforms 6 are respectively fixedly connected to the two end faces of the fixed base 5. The support block 22 is fixedly connected to the middle of the top of the receiving box 1. A threaded rod 17 is rotatably provided between the inner side of the connecting platform 6 and the side wall of the support block 22. A threaded sleeve 10 is threadedly connected to the surface of the threaded rod 17. The moving platform 11 is fixedly connected to the surface of the threaded sleeve 10 at the same end. Both ends of the bottom of the receiving box 1 are provided with a drive mechanism to drive the threaded rod 17 at the same end to rotate.

[0023] After the threaded rod 17 is in operation, it can drive 10 to move along its surface, which in turn drives the moving table 11 to move in the horizontal direction, so as to adjust the distance between the two spindle assemblies 14.

[0024] Furthermore, the drive mechanism includes a motor 7, which is fixedly connected to the bottom end of the fixed base 5. The outer end of the threaded rod 17 extends rotatably to the outside of the connecting platform 6. The output shaft of the motor 7 and the outer end of the threaded rod 17 are both fixedly connected to pulleys 8. The two pulleys 8 at the same end are connected by a transmission belt 9.

[0025] After the motor 7 starts working, it can drive the pulley 8 on the threaded rod 17 to rotate through the transmission belt 9 on its output shaft, thereby driving the threaded rod 17 to work.

[0026] Furthermore, the front and rear sides of the lower surface of the moving platform 11 are vertically fixedly connected with limit rods 18. The bottom end of the surface of the limit rod 18 is rotatably provided with a guide wheel 19 that abuts against the side wall of the fixed seat 5. The front and rear sides of the fixed seat 5 are both horizontally provided with limit grooves 20 for the guide wheel 19 to rotate.

[0027] When disassembling the spindle assembly 14, there is no need to remove the guide wheel 19. After reinstalling the spindle assembly 14, the guide wheel 19 rolls inside the limit groove 20 during the movement of the moving table 11, ensuring the accuracy of movement and improving the quality of the finished product.

[0028] Furthermore, a cooling fan 15 is provided at the outer end of the surface of the spindle assembly 14.

The bottom end of the electric telescopic rods 2 is fixedly connected to the upper surface of the base plate 3, and the surface of the base plate 3 is provided with several mounting holes 4.

[0030] After the electric telescopic rod 2 extends and moves, the support position of the base plate 3 can be adjusted to adjust the support height of the fixed seat 5, making it convenient for processing different workpieces.

[0031] During operation, after the motor 7 starts working, it drives the pulley 8 on the threaded rod 17 to rotate through the transmission belt 9 on its output shaft, thereby driving the threaded rod 17 to work. After the threaded rod 17 works, it can drive 10 to move along its surface, thereby driving the moving table 11 to move in the horizontal direction, so as to adjust the distance between the two spindle assemblies 14 to adapt to different processing requirements. When the spindle assembly 14 needs to be inspected and maintained, simply remove the bolt 12 and open the clamping seat 21 to remove the spindle assembly 14 from the inside of the placement seat 13. When disassembling the spindle assembly 14, there is no need to remove the guide wheel 19. After reinstalling the spindle assembly 14, the guide wheel 19 rolls inside the limit groove 20 during the movement of the moving table 11 to ensure the accuracy of the movement.
