[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Example 1

[0034] like Figures 1 to 6 As shown, a specific embodiment of the multi-station milling machine of this utility model includes a base 4, a clamping part 3, a cutting head part 2, a lubrication part 1, and a chip collection part 6;

[0035] The base 4 serves as the supporting foundation for the entire equipment, providing a stable mounting platform for other components; the clamping part 3 is mounted on the base 4 and is used to clamp and fix the aluminum sample 13; the cutting head part 2 is located above the clamping part 3 and is responsible for milling the aluminum sample 13; the lubrication part 1 is installed on one side of the base 4 to provide lubrication for the entire equipment; the chip collection part 6 is located below the clamping part 3 and is used to collect the chips generated during the milling process.

[0036] The lubrication section 1 consists of an oil pump (AMR-II-150S / 03IIM), an oil filter (FX-1), nylon tubing and nylon protective tubing, and an oil distribution plate. After the equipment travels a certain distance, the oil pump automatically pumps oil to lubricate the guide rail slider pair and ball screw pair. The lubrication section 1 uses existing technology without any improvements, and will not be described in detail here.

[0037] The chip collection section 6 consists of a baffle, an air nozzle, a chip guide plate, and a chip collector. During milling, the chips enter the collector along the guide plate under the combined action of the airflow and the baffle. The chip collection section 6 adopts existing technology without any improvements, and will not be described in detail here.

[0038] Fixture section 3 includes a fixture assembly and a pressure plate assembly 5:

[0039] The clamping assembly is used to clamp the aluminum sample 13. It includes a support 25, a support mechanism, and a clamping mechanism. The support mechanism includes a vertical plate 27 installed at the middle of the upper part of the support 25. Horizontal plates 28 are fixed on both sides of the vertical plate 27. Linear bearings 31 are installed on the horizontal plates 28. A guide shaft 32 is set above the linear bearings 31. A support plate 22 is fixed at the top of the guide shaft 32 for placing the aluminum sample 13. A spring 30 is fitted around the guide shaft 32. The spring 30 is located between the horizontal plates 28 and the support plate 22, allowing the support plate 22 to move up and down and return to its original position. The clamping mechanism has a fixed plate 26 installed on the support 25 and arranged parallel to both sides of the vertical plate 27. A first cylinder 15 is installed on the fixed plate 26. The extended end of the first cylinder 15 is connected to a movable clamping plate 29. A fixed clamping plate 23 is installed at the top of the vertical plate 27. The movable clamping plate 29 and the fixed clamping plate 23 cooperate to clamp the aluminum sample 13. A guide rail 24 is installed between the fixed plate 26 and the vertical plate 27 to guide the movable clamping plate 29. The first cylinder 15 is also equipped with... A front sensor 20 and a rear sensor 21 are provided. The front sensor 20 detects the clamping status of the aluminum sample 13, and the rear sensor 21 detects whether the movable clamping plate 29 has returned to its original position, preventing the aluminum sample 13 from jumping out and injuring people during milling or when the pressure plate is opened. The front sensor 20 and the rear sensor 21 are magnetic switch sensors. The sensors transmit and receive signals by the change in magnetic field caused by the change in position of the permanent magnet set on the extended end (i.e., piston rod) of the first cylinder 15 during the extension or retraction of the piston rod. In this utility model, when the front sensor 20 detects that the piston rod has extended to the position, it indicates that the movable clamping plate 29 has clamped the aluminum sample 13; when the rear sensor 21 detects that the piston rod has retracted to its original position, it indicates that the movable clamping plate 29 has been reset. The principle of the magnetic switch sensor detecting the change in magnetic field and transmitting and receiving signals is existing technology and will not be described in detail here. In addition, V-shaped clamping grooves and anti-slip grooves are provided on both sides of the fixed clamping plate 23 to enhance the clamping effect on the aluminum sample 13.

[0040] The pressure plate assembly 5 includes a second cylinder 19, the piston rod of which is connected to a rocker arm 38. The other end of the rocker arm 38 is connected to an active synchronous shaft 36. The active synchronous shaft 36 is mounted on a bearing seat 35. A parallel passive synchronous shaft 37 is also mounted on the bearing seat 35. The active synchronous shaft 36 and the passive synchronous shaft 37 are fitted together to install a parallel linkage mechanism 33. The pressure plate body 16 is mounted on the upper part of the parallel linkage mechanism 33. The second cylinder 19 drives the pressure plate body 16 to press down, pressing the uneven upper surface of the aluminum sample 13 to the same height, which is convenient for subsequent milling. At the same time, pressure plate position sensors 18 are provided at both ends of the fixture assembly corresponding to the pressing position of the pressure plate body 16. These sensors are used to detect the position of the pressure plate assembly 5 and provide signals for the fixture assembly to perform clamping operations.

[0041] Cutter head section 2: Cutter head section 2 includes a moving module 14, which is fixed on the base 4. It includes components such as a ball screw pair and a guide rail slider pair. The moving module 14 adopts existing technology products without any improvements, and its principle will not be described in detail. 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. The module motor 34 drives the lifting column 9 to move laterally. A lifting motor 10 and a power head 11 are installed on the lifting column 9. The lifting motor 10 drives the power head 11 to move up and down. The power head 11 consists of an upper cutter head motor 12 and a lower cutter disc 17. The cutter head motor 12 drives the cutter disc 17 to rotate, realizing the milling operation on the aluminum sample 13. To ensure the safe movement of the cutter head section 2, module limit position sensors 7 are installed at both ends of the moving module 14, and column limit position sensors 8 are installed at both ends of the lifting column 9.

[0042] Both the fixture group and the pressure plate group 5 are set up in two groups. Each fixture group has eight single fixtures. Each single fixture includes two symmetrically arranged workstations, so that a maximum of 32 aluminum samples 13 can be placed at one time, which greatly improves the processing efficiency.

[0043] The control system of this milling machine adopts the existing Siemens PLC S7-1200 series.

[0044] The working principle of this utility model:

[0045] Manually place all or part of the aluminum sample 13 onto the tray 22 of the fixture assembly. After placement, close the equipment protective door and start the equipment.

[0046] When the piston rod of the second cylinder 19 of the pressure plate assembly 5 retracts, the pressure plate body 16 is pressed down under the combined action of the rocker arm 38, the parallel linkage 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 clamping assembly is compressed, so that the upper surface of the aluminum sample 13 is at the same height under the combined 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. The extended end of the first cylinder 15 pushes the movable clamping plate 29, which cooperates with the fixed clamping plate 23 to clamp and fix the aluminum sample 13, and the pressure plate body 16 is retracted.

[0047] The cutter head motor 12 starts, and the power head 11 descends to a certain height according to the program setting under the drive of the lifting motor 10. Then, the module motor 34 drives the lifting column 9 and the power head 11 to start the milling movement to the right. During the milling process, the cutter head 17 rotates at high speed under the drive of the cutter head motor 12 to mill the aluminum sample 13. If the process requires only one cut, the cutter head 17 stops rotating when the cutter head part 2 completes the milling and returns to the original point. If multiple cuts are required, the cutter head 17 will continue to rotate until the last milling is completed before stopping and returning to the original point.

[0048] During milling, the air nozzle of the chip collection section 6 blows out airflow, which, under the combined action of the airflow and the baffle, guides the aluminum chips along the chip guide plate into the chip collector, thus collecting the aluminum chips. After milling, the power head 11 rises back to its original position under the drive of the lifting motor 10. The piston rod of the second cylinder 19 of the pressure plate group 5 retracts again to control the pressure plate body 16 to press down on the aluminum sample 13, preventing the aluminum sample 13 from jumping out. After reaching the position, the piston rod of the first cylinder 15 of the fixture group retracts, and the movable clamping plate 29 releases the aluminum sample 13, releasing the clamping of the aluminum sample 13. Subsequently, 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, returning to its original position. The equipment completes one processing cycle and waits for the next operation.

[0049] The modules, column limit position sensors, moving modules, pressure plate position sensors, front sensors, and rear sensors mentioned in this article are all general standard parts or parts known to those skilled in the art, and have not been modified. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods, so they will not be described in detail here.

[0050] While the specific embodiments of this utility model have been described in detail above, this utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model. Modifications or variations that do not involve creative labor are still within the protection scope of this utility model.
