[0038] Combination Figure 2 , Figure 7 and Figure 8 , and also includes: racks 601 fixedly installed at the bottom of the left and right sides of the cover plate 501, and two racks 601 are provided; a transmission component is arranged between the rotating shaft 304 and the machine table 101, and the transmission component cooperates with the rack 601 to realize the change conversion between the displacement of the cover plate 501 and the expansion of the installation arm 305; the combination of the rack 601 and the transmission component is provided with two groups in total, which are used to control the two rotating shafts 304 respectively.

[0039] The transmission assembly includes: a mounting frame 602 rotatably mounted on the rotating shaft 304; a bevel gear x603 fixedly mounted on the rotating shaft 304; an axis frame 604 fixedly mounted in the machine 101; a cross shaft 605 slidably mounted on the axis frame 604, a circular shaft section is provided at the end of the cross shaft 605, and the circular shaft section is rotatably mounted with the mounting frame 602; a bevel gear y606 fixedly mounted at the end of the cross shaft 605, the bevel gear y606 meshing with the bevel gear x603; a bracket 607 fixedly mounted in the machine 101, the cross shaft 605 passes through the bracket 607, and has no mating relationship with the bracket 607; a gear 608 rotatably mounted on the bracket 607, the gear 608 is cross-matched with the cross shaft 605, so that transmission can be performed between the two.

[0040] When the cover plate 501 moves forward to open the installation cavity 102, the rack 601 will move to mesh with the gear 608, and the gear 608 will be rotated by the moved rack 601. The gear 608 drives the bevel gear y606 to rotate through the cross shaft 605, and the bevel gear y606 then rotates through the transmission bevel gear x603 to drive the shaft 304 to rotate, so that the installation arm 305 and the movable column 306 are automatically deployed. In the process of the shaft 304 moving left and right, the mounting frame 602 and the bevel gear x603 are And the bevel gear y606 will move with the rotating shaft 304, and the cross shaft 605 will move relative to the shaft frame 604 and the gear 608, while the transmission function is still maintained through the cross shaft 605; when the pin 505 fixes the position of the cover plate 501, the position of the rack 601 will also be fixed, so that when the rack 601 is engaged with the gear 608, the position of the rack 601 is fixed, which will keep the position of the mounting arm 305 fixed, so that the mounting arm 305 can fix the workpiece more stably.

[0042] When the rack 601 is about to move to mesh with the gear 608, the rack 601 will be squeezed by the inclined surface of the wedge block 701 to leave the teeth of the gear 608, and then the rack 601 can control the gear 608 to rotate and unfold the mounting arm 305; and after the rack 601 is disengaged from the gear 608, the rack 601 is then disengaged from the wedge block 701, and the reset spring z702 is reset, so that the wedge block 701 is stuck in the teeth of the gear 608 to fix the position of the gear 608. In this way, when the present invention is not in use, the position of the transmission assembly can be kept fixed, so that the rack 601 can cooperate with the transmission assembly again, avoiding incomplete cooperation between the rack 601 and the transmission assembly due to accidental position changes of the transmission assembly, thereby ensuring the accuracy of the cooperation between the rack 601 and the transmission assembly.

[0043] In summary, the complete process of the cutting machine is:

[0044] 1. Pull out the latch 505 upwards, turn the unfolding handle 503, use the handle 503 to move the cover plate 501 forward to open the installation cavity 102, and then insert the latch 505 back to the position of fixing the cover plate 501. After being released, the handle 503 is automatically turned back by the reset torsion spring y504; and in the process of the cover plate 501 moving forward, the rack 601 first squeezes the wedge block 701 and the teeth of the gear 608 to disengage, and then the rack 601 is meshed with the gear 608, so that it is transmitted through the entire transmission assembly, so that the installation arm 305 is automatically unfolded.

[0045] 2. Move the extension plate 502 backward and clamp it to the rear of the machine table 101, place the workpiece on the cover plate 501 and the extension plate 502, and place it between the mounting arms 305. Then, adjust the position of the workpiece on the cutting machine according to the required cutting position of the workpiece and the tangent position of the cutter 202.

[0046] 3. After the workpiece is placed, the screw rod 309 is rotated to control the two mounting arms 305 to approach each other so that the two mounting arms 305 clamp the workpiece. During the process, the movable column 306 is squeezed by the surface of the workpiece and retracted toward the mounting arm 305, and automatically adjusted to a state of fitting with the workpiece according to the size of the workpiece. At the same time, the balanced pressure of the hydraulic oil is transmitted to each movable column 306, so that each movable column 306 stably applies pressure to fix the workpiece.

[0047] 4. Start the cutter 202, manually control the cutter 202 to move down until it contacts the workpiece for cutting. After completion, release the cutter 202, reset the torsion spring x203 to move the cutter 202 upward. If multiple parallel cuttings are required, directly push the workpiece backward. The workpiece can move stably under the action of the ball 307, and the movable column 306 changes adaptively with the position of the ball 307.

[0048] 5. After all the cutting of the workpiece is completed, reverse the screw 309 to control the mounting arm 305 to release the workpiece, and the reset spring x308 restores the position of all the movable columns 306. Then remove the workpiece, move the extension plate 502 forward and retract it onto the cover plate 501, pull out the latch 505 upward, and move the cover plate 501 backward to close the mounting cavity 102. At the same time, the mounting arm 305 is retracted into the mounting cavity 102, and the wedge block 701 is inserted into the teeth of the gear 608 to fix the position of the gear 608. Finally, the latch 505 is inserted into the cover plate 501 to fix the cover plate 501 again.

[0049] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
