[0036] The lubrication part 1 is composed of an oil pump (AMR-II-150S / 03IIM), an oil filter (FX-1), a nylon tube and a nylon protective tube, an oil distribution plate, etc. After the equipment runs a certain distance, the oil pump automatically pumps oil to lubricate the guide rail slider pair and the ball screw pair of the equipment.

[0038] The fixture part 3 comprises a fixture group and a pressure plate group 5:

[0039] The clamp group is used to clamp the aluminum sample 13, which includes a support 25, a supporting mechanism and a clamping mechanism; the supporting mechanism includes a vertical plate 27 installed in the middle position of the upper part of the support 25, and horizontal plates 28 are fixed on both sides of the vertical plate 27.

[0042] Cutter head part 2: The cutter head part 2 includes a moving module 14, which is fixed on the base 4, and includes components such as a ball screw pair, a guide rail slider pair, etc. The moving module 14 adopts existing technology products without any improvement, and its principle is no longer repeated; a module motor 34 is installed at the end of the moving module 14, and a lifting column 9 is installed on the moving module 14, and the module motor 34 drives the lifting column 9 to move horizontally; a lifting motor 10 and a power head 11 are installed on the lifting column 9, and the lifting motor 10 drives the power head 11 to move up and down; the power head 11 is composed of an upper cutter head motor 12 and a lower cutter disc 17, and the cutter head motor 12 drives the cutter disc 17 to rotate to realize the milling operation of the aluminum sample 13; to ensure the safe movement of the cutter head part 2, module limit position sensors 7 are installed at the left and right ends of the moving module 14, and column limit position sensors 8 are installed at the upper and lower ends of the lifting column 9.

[0044] The control system of this milling prototype adopts the existing product Siemens PLC S7-1200 series.

[0045] Working principle of the present invention:

[0046] Manually place all or part of the aluminum sample 13 on the support plate 22 of the fixture group, close the equipment protection door after the placement is completed, and start the equipment;

[0047] The piston rod of the second cylinder 19 of the pressure plate group 5 contracts, and the pressure plate body 16 is pressed down by the joint action of the rocker arm 38, the parallel connecting rod mechanism 33, the active synchronous shaft 36 and the passive synchronous shaft 37; at the same time, the spring 30 at the bottom of the clamp group is compressed, so that the upper plane of the aluminum sample 13 is at the same height under the joint action of the pressure plate body 16 and the spring 30; when the pressure plate position sensor 18 detects that the pressure plate has reached the fixed position, it sends a signal to the control system, and the first cylinder 15 of the clamping mechanism starts to work, and the extended end of the first cylinder 15 pushes the movable clamp 29, which cooperates with the fixed clamp 23 to clamp and fix the aluminum sample 13, and the pressure plate body 16 is retracted;

[0049] During the milling process, the air nozzle of the chip collecting part 6 blows out an air flow, and the aluminum chips are sent into the chip collector along the chip guide plate under the combined action of the air flow and the baffle, thereby realizing the collection of the aluminum chips; after the milling is completed, the power head 11 rises back to its original position under the drive of the lifting motor 10, and the piston rod of the second cylinder 19 of the pressure plate group 5 contracts again to control the pressure plate body 16 to press down the aluminum sample 13 to prevent the aluminum sample 13 from popping out; after being in place, the piston rod of the first cylinder 15 of the clamp group retracts, and the movable clamp 29 releases the aluminum sample 13 and releases the clamping of the aluminum sample 13; then the piston rod of the second cylinder 19 of the pressure plate group 5 extends, and the pressure plate body 16 releases the pressure on the aluminum sample 13 and returns to its original position. The equipment completes a processing cycle and waits for the next operation.
