Detailed Implementation

[0016] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0017] This application discloses a precision aluminum forging cutting device, including a frame 1, a workbench 3 fixedly installed on the upper surface of the frame 1, an air chamber 13 opened inside the workbench 3, a pump 2 fixedly connected to the frame 1, the air port of the pump 2 being connected to the air chamber 13 through a pipe, a uniformly distributed through hole 4 opened on the upper surface of the workbench 3, a telescopic rod 15 set at the center inside the through hole 4, a spring 14 fixedly connected between the lower end of the telescopic rod 15 and the upper surface inside the air chamber 13, a sealing head 16 fixedly connected to the lower end of the telescopic rod 15, the diameter of the sealing head 16 being adapted to the inner diameter of the through hole 4.

[0018] Furthermore, all telescopic rods 15 are configured as inverted T-shapes, with the diameter of the rod portion of the telescopic rod 15 being smaller than the diameter of the through hole 4. The spring 14 is sleeved on the outer surface of the lower end of the telescopic rod 15, with the lower end of the spring 14 fixedly connected to the head of the telescopic rod 15 and the upper end of the spring 14 fixedly connected to the upper surface inside the air chamber 13.

[0019] In this embodiment, the aluminum forging to be cut is placed on the workbench 3. The telescopic rod 15 of the aluminum profile covering part moves down, causing the sealing head 16 at its lower end to move out of the through hole 4. Then, the pump 2 is used to draw air, so that the air chamber 13 is in a negative pressure state, which can adsorb the aluminum forging and fix the aluminum forging. It will not block the aluminum profile when fixing it, which is convenient for cutting operation.

[0020] In addition, when the telescopic rod 15 moves down, the spring 14 extends. After the aluminum profile is cut and removed from the workbench 3, the extended spring 14 returns to its original position, thereby driving the telescopic rod 15 and the sealing head 16 to move back to their original position.

[0021] Furthermore, a support frame 5 is provided on the upper surface of the frame 1. A laser cutting machine 8 is connected to the support frame 5 through a transverse moving mechanism, and the support frame 5 is connected to the frame 1 through a longitudinal moving mechanism.

[0022] Furthermore, the lateral movement mechanism includes a first lead screw 7 rotatably mounted on the top of the support frame 5, a first ball bearing seat 6 sleeved on the outer surface of the first lead screw 7, a first motor 9 fixedly mounted on the outer surface of the support frame 5, the output shaft of the first motor 9 being fixedly connected to one end of the first lead screw 7, and a laser cutting machine 8 fixedly mounted on the lower surface of the first ball bearing seat 6.

[0023] Furthermore, the longitudinal moving mechanism includes a second lead screw 11 rotatably mounted on one side of the outer surface of the frame 1, a second ball bearing seat 12 sleeved on the outer surface of the second lead screw 11, a second motor 10 fixedly mounted on the surface of the frame 1, the output end of the second motor 10 being fixedly connected to one end of the second lead screw 11, the second ball bearing seat 12 being fixedly connected to one side of the bottom of the support frame 5, and the other side of the bottom of the support frame 5 being slidably connected to the frame 1.

[0024] In this embodiment, the ball screw is an existing transmission element whose main function is to convert rotary motion into linear motion, which will not be elaborated here. In actual use, the first motor 9 or the second motor 10 needs to be connected to an external power source and driven to rotate in both directions to move the first ball seat 6 or the second ball seat 12.
