[0043] In the present invention, a method for operating a track segment precision cutting device is provided, and the method comprises the following steps:

[0044] Step 1: Place the chain track segments that need to be finely cut on the positioning blocks 17 on different bearing blocks 16 in sequence. The positioning blocks 17 on the bearing blocks 16 can position the chain track segments that need to be finely cut;

[0045] Step 2: The output shaft of the first rotating motor 5 drives the rotating disk 8 to rotate, and the rotating disk 8 can transport the chain track segments through the clamping block 29, the connecting tube 12, the rotating rod 13, the bearing block 16 and the positioning block 17, so that the chain track segments to be processed are sequentially transported to the bottom of the corresponding pressing block 22;

[0046] Step 3: The first hydraulic cylinder 20 can drive the pressing block 22 to move downward, and the pressing block 22 can press the chain track segment and the bearing block 16 downward, so that the rotating rod 13 moves downward, and the limiting groove 15 at the bottom of the rotating rod 13 is sleeved on the outside of the cross-shaped limiting block 14. The output shaft of the second rotating motor 6 can drive the rotating rod 13 to rotate through the cross-shaped limiting block 14 and the limiting groove 15. When the rotating rod 13 rotates, it can drive the chain track segment to rotate through the bearing block 16 and the positioning block 17, so as to facilitate precision cutting of different positions on the chain track segment;

[0047] Step 4: The electric slider 25 can drive the second hydraulic cylinder 21 to move in the horizontal direction. The second hydraulic cylinder 21 can drive the fine cutting knife 27 to move in the horizontal direction through the moving block 26 and the third rotating motor 7. After the fine cutting knife 27 is moved to correspond to the chain track segment, the third rotating motor 7 can drive the fine cutting knife 27 to rotate, so as to perform fine cutting processing on the chain track segment through the fine cutting knife 27.

[0048] The working principle of the present invention is as follows: during use, the supporting legs 3 are stably placed at the position where they need to be used, which is convenient for the stable use of the supporting legs 3. The supporting legs 3 can support and limit the first mounting plate 1 and the various components assembled on the first mounting plate 1, which helps to stably use the first mounting plate 1 and the various components assembled on the first mounting plate 1. The first mounting plate 1 can support and limit the fixing block 4, which is convenient for the stable use of the fixing block 4. The fixing block 4 can support and limit the second mounting plate 2 and the various components assembled on the second mounting plate 2, which helps to stably use the second mounting plate 2 and the various components assembled on the second mounting plate 2.

[0049] The chain track segments that need to be fine-cut are placed on the positioning blocks 17 on different bearing blocks 16 in sequence. The bearing blocks 16 can position the chain track segments through the positioning blocks 17. The first rotating motor 5 on the upper surface of the first mounting plate 1 is further opened. The first mounting plate 1 can fix and limit the first rotating motor 5, which is convenient for the stable use of the first rotating motor 5. When the first rotating motor 5 is opened, the output shaft of the first rotating motor 5 can drive the rotating disk 8 to rotate. When the rotating disk 8 rotates, the chain track segments can be transported through the retaining holes 9, the slots 30, the blocks 29, the connecting tubes 12, the rotating rods 13, the bearing blocks 16 and the positioning blocks 17. After the chain track segments that need to be fine-cut are transported to the positions corresponding to the pressing blocks 22, the first hydraulic cylinder 20 on the upper surface of the second fixing plate 19 is opened. The second fixing plate 19 can fix and limit the first hydraulic cylinder 20, which is convenient for the stable use of the first hydraulic cylinder 20.

[0050] When the first hydraulic cylinder 20 is in the open state, the output rod of the first hydraulic cylinder 20 can drive the pressure block 22 to move downward, and the pressure block 22 can press the chain track section and the positioning block 17 downward through the positioning groove 28, so as to press the rotating rod 13 and the connecting tube 12 downward through the bearing block 16. When the connecting tube 12 moves downward, the spring 10 can be squeezed downward through the connecting ring 11. When the rotating rod 13 moves downward, it will be sleeved on the outer side of the cross-shaped limiting block 14 through the limiting groove 15. When it is necessary to adjust the angle of the chain track section to be finely cut, the second rotating rod 13 on the upper surface of the first mounting plate 1 is adjusted. The second rotating motor 6 is opened, and the first mounting plate 1 can fix and limit the second rotating motor 6, which is helpful for stably using the second rotating motor 6. When the second rotating motor 6 is opened, the output shaft of the second rotating motor 6 will drive the rotating rod 13 to rotate through the cross-shaped limit block 14 and the limit groove 15. When the rotating rod 13 rotates, it can drive the chain track section to rotate through the bearing block 16 and the positioning block 17, so as to adjust the position on the chain track section that needs to be fine-cut. When the chain track section and the positioning block 17 rotate, they can drive the pressure block 22 to rotate along the output rod of the first hydraulic cylinder 20.

[0051] After the position on the chain track segment that needs to be fine-cut is adjusted to face the fine-cutting knife 27, the electric slider 25 is opened, so that the electric slider 25 moves along the guide rail 24 toward the chain track segment. When the electric slider 25 moves, the moving block 26 can be driven to move by the second hydraulic cylinder 21. When the moving block 26 moves, the fine-cutting knife 27 can be driven to move by the third rotating motor 7, so that the fine-cutting knife 27 moves toward the chain track segment. The third rotating motor 7 is further turned on. When the third rotating motor 7 is turned on, the third rotating motor 7 is turned on. The output shaft of the motor 7 can drive the fine cutting knife 27 to rotate. When the fine cutting knife 27 rotates, it can perform fine cutting on the chain track segment. When the height of the fine cutting knife 27 needs to be adjusted, the second hydraulic cylinder 21 is opened. When the second hydraulic cylinder 21 is opened, the output rod of the second hydraulic cylinder 21 can drive the moving block 26 to move in the vertical direction. When the moving block 26 moves in the vertical direction, it can drive the fine cutting knife 27 to move in the vertical direction through the third rotating motor 7, which helps the fine cutting knife 27 to perform fine cutting on the chain track segment.

[0052] After the fine cutting process on the chain track segment is completed, the first hydraulic cylinder 20 is further used to drive the pressure block 22 to move upward, so that the pressure block 22 cancels the pressure on the chain track segment and the positioning block 17. Under the action of the elastic force of the spring 10 itself, the connecting ring 11 will move upward to reset. When the connecting ring 11 moves upward, it can drive the rotating rod 13 to move upward through the connecting tube 12, so that the limiting groove 15 on the rotating rod 13 is separated from the cross-shaped limiting block 14, so as to facilitate the rotation of the rotating disk 8 by the first rotating motor 5, which is helpful for conveying different chain track segments and is conducive to continuous fine cutting of the chain track segments. The rotating disk 8 can limit the connecting tube 12 through the clamping groove 30 and the clamping block 29, so as to facilitate the stable movement of the connecting tube 12.

[0053] During use, it helps to continuously carry out precision cutting of the chain track segments. When precision cutting of the chain track segments is carried out, the insertion and removal of the chain track segments are relatively convenient, so that the chain track segments can be processed conveniently, which helps to ensure the work efficiency of precision cutting of the chain track segments and is conducive to the use of the precision cutting device.
