The output end of the fifth motor passes through the right side wall of the support frame and is fixedly connected to a second bidirectional lead screw inside the support frame. The left and right ends of the outer surface of the second bidirectional lead screw are threaded with third threaded seats. Mounting plates are fixedly connected to the upper ends of the two third threaded seats. Driven rollers are rotatably connected to the upper ends of the two mounting plates. The front and rear sides of the upper surface of the support frame are fixedly connected with third moving guide rails. The front and rear ends of the mounting plates are slidably connected to the two third moving guide rails respectively.

2. The apparatus for cutting crystal rods with diamond wire according to claim 1, characterized in that: The pushing assembly includes an L-shaped plate fixedly connected to the upper rear side of the support frame. A connecting sleeve is fixedly connected to the upper part of the L-shaped plate via a support rod. A threaded sleeve is slidably connected inside the connecting sleeve. Limiting blocks are fixedly connected to both sides of the outer surface of the threaded sleeve. The shape of the threaded sleeve and the limiting blocks is adapted to the inside of the connecting sleeve. A pushing plate is fixedly connected to the front end of the threaded sleeve. A sixth motor is fixedly installed on the rear side of the L-shaped plate. The output end of the sixth motor passes through the rear side wall of the connecting sleeve and is fixedly connected to a third threaded rod. The third threaded rod is threadedly connected to the inside of the threaded sleeve.

3. The method of using the equipment for cutting crystal rods with diamond wire according to claim 2, characterized in that, include: S1: First, the first adjusting handwheel is rotated to turn the adjusting threaded rod, thereby causing the adjusting block to drive the tensioning wheel to move, thus reducing the tension of the cutting diamond wire. Then, the second motor drives the first bidirectional lead screw to rotate, and the distance between the first protective shell and the second protective shell is adjusted through the threaded engagement relationship, so as to adapt to crystal rods of different diameters. After the adjustment is completed, the first adjusting handwheel is rotated again to adjust the tension of the cutting diamond wire to a suitable size. S2: Then, the fifth motor drives the second bidirectional lead screw to rotate, thereby adjusting the distance between the two driven rollers to adapt to crystal rods of different diameters. Next, the crystal rod is placed above the two driven rollers. Then, the cylinder output end in the drive assembly extends, so that the drive roller presses the crystal rod. The second adjusting handwheel drives the synchronous wheel to rotate, further driving the second threaded rod to rotate, thereby adjusting the height of the sliding plate to adapt to the crystal rod diameter. The output end of the fourth motor drives the drive roller to rotate, thereby driving the crystal rod to rotate. S3: The sixth motor in the pusher assembly drives the third threaded rod to rotate. The third threaded rod engages with the threaded sleeve, causing the threaded sleeve to extend out of the connecting sleeve and push the crystal rod to move through the pusher plate. S4: Then the third motor drives the second guide wheel to rotate, and through the transmission relationship, the cutting diamond wire rotates. At this time, the first motor drives the first threaded rod to rotate, and through the first threaded block, it drives the fixed base to move, which in turn drives the cutting assembly to move to the right. The rotating cutting diamond wire will cut the crystal rod. After the cutting is completed, the first motor reverses to reset the cutting assembly. The pushing assembly will push the crystal rod to move again, and then perform the next cutting.
