[0029] Example 1
[0030] like Figures 1-4 As shown in the figure, the rotary milling machine for metal parts proposed in this embodiment includes a frame 1, a motor 8, a laser pointer 20, a distance sensor 21, a horizontal drive assembly, a vertical drive assembly, a lifting frame assembly, a protective mechanism, a dust collection mechanism, and a displacement detection device.
[0031] A support plate 2 is installed above the frame 1. Furthermore, a PLC controller 3 is installed on the frame 1. A horizontal drive assembly is used to drive the workpiece to translate on the support plate 2. A fixed frame 19 is connected to the frame 1. A laser pointer 20 and a distance sensor 21 are both installed on the fixed frame 19, with the laser pointer 20 tilted. A vertical drive assembly is used to drive the support plate 2 to rise and fall. The vertical drive assembly includes a first servo cylinder 4, a lifting plate 22, and two connecting sliders 23. The lifting plate 22 is located below the table surface of the frame 1. The first servo cylinder 4 is installed on the frame 1, and its output shaft is connected to the lifting plate 22. The two connecting sliders 23... All three components are slidably mounted on the lifting plate 22 along the longitudinal direction. The upper end of the frame 1 has two first sliding holes 101 for sliding two connecting sliders 23. Both connecting sliders 23 are fixedly connected to the support plate 2. The lifting frame assembly is mounted on the upper end of the frame 1. The lifting frame assembly includes an L-shaped mounting bracket 5, a housing 6, and a second servo cylinder 13. The housing 6 is fixedly mounted on the frame 1. The bottom end of the L-shaped mounting bracket 5 is slidably mounted on the inner side of the housing 6. The second servo cylinder 13 is mounted on the inner side of the housing 6 and its output shaft is connected to the L-shaped mounting bracket 5. The motor 8 is mounted on the housing 6, and a milling cutter 9 is mounted on the rotating shaft of the motor 8.
[0032] The protective mechanism includes a first sleeve 10 and a second sleeve 11. The first sleeve 10 is fixedly mounted on the motor 8, and the second sleeve 11 is slidably connected to the first sleeve 10. The bottom end of the second sleeve 11 is flush with the bottom end of the milling cutter 9. A second sliding hole 501 is provided on the L-shaped mounting bracket 5. A connecting rod 12 is connected to the second sleeve 11. An elastic component is connected between the connecting rod 12 and the L-shaped mounting bracket 5. The elastic component includes a guide slide rod 24 and a spring 25. The guide slide rod 24 is vertically arranged in the second sliding hole 501, and the connecting rod 12... The sliding mechanism is mounted on the guide slide rod 24, and the spring 25 is sleeved on the guide slide rod 24; the dust collection mechanism is used to absorb debris inside the protective mechanism, and the dust collection mechanism includes a vacuum cleaner 7, and a suction pipe 71 is connected between the input end of the vacuum cleaner 7 and the inside of the second sleeve 11; the displacement detection device is used to detect the moving distance of the second sleeve 11, and the displacement detection device includes a magnetic scale 26 and a magnetic head 27. The magnetic scale 26 is vertically mounted on the L-shaped mounting bracket 5, and the magnetic head 27 is slidably mounted on the magnetic scale 26 and connected to the connecting rod 12.
[0033] It should be added that a hose can be connected to the first sleeve 10. After the hose is connected to the pump body, the pump body delivers coolant into the first sleeve 10, thereby achieving the cooling treatment of the milling cutter 9.
[0034] During operation, the metal sheet to be processed is placed on the support plate 2 and then fixed. The distance sensor 21 is used to measure the distance between itself and the upper surface of the sheet and feeds the data back to the PLC controller 3. The distance between the distance sensor 21 and the sheet is preset on the PLC controller 3, for example, 10cm. When the distance between the distance sensor 21 and the sheet is exactly 10cm, the light spot projected by the laser pointer 20 on the sheet is located directly below the milling cutter 9. The construction personnel can easily determine the processing position on the sheet based on the position of the light spot. If there is a deviation between the detected data and the set value, the first servo cylinder 4 needs to be activated to drive the support plate 2 to make fine adjustments to the height, so that the distance between the upper surface of the sheet and the distance sensor 21 meets the requirements. This ensures that the light spot projected by the laser pointer 20 is located directly below the milling cutter 9, which is convenient for subsequent positioning work.
[0035] After determining the processing position on the plate, the second servo cylinder 13 is activated to drive the L-shaped mounting bracket 5 and the milling cutter 9 to move downwards. At the same time, the motor 8 is activated to drive the milling cutter 9. The milling cutter 9 rotates at high speed to cut or drill holes in the workpiece. When the second sleeve 11 presses on the upper surface of the workpiece, and the milling cutter 9 continues to move downwards, the spring 25 is further compressed, so that the milling cutter 9 is always placed inside the protective mechanism, thereby preventing the chips generated during the processing from flying outwards in all directions.
[0036] Because the bottom end of the second sleeve 11 is flush with the bottom end of the milling cutter 9, when the milling cutter 9 moves downward, a relative movement occurs between the milling cutter 9 and the second sleeve 11. The movement of the second sleeve 11 drives the connecting rod 12 and the magnetic head 27 to move. The magnetic head 27 can detect the downward displacement of the milling cutter 9 by sliding on the magnetic scale 26, thereby enabling the monitoring of the drilling depth of the milling cutter 9. Before the milling cutter 9 contacts the workpiece surface, the relative displacement between the second sleeve 11 and the milling cutter 9 is zero. The magnetic scale 26 can only detect data changes during the drilling process, and its detection accuracy is high.
[0037] Example 2
[0038] like Figure 1 and Figure 2As shown in this embodiment, a rotary milling machine for metal parts is proposed. Compared with Embodiment 1, in this embodiment, the horizontal drive assembly includes a third servo cylinder 14, a fourth servo cylinder 15, a U-shaped sliding frame 16, a fifth servo cylinder 17, and a clamping plate 18. The third servo cylinder 14 is mounted on the lifting plate 22, and its output shaft is connected to a slider 23 on one side. The fourth servo cylinder 15 is fixedly mounted on the side of the support plate 2. The U-shaped sliding frame 16 is connected to the output shaft of the fourth servo cylinder 15. The fifth servo cylinder 17 is mounted on the U-shaped sliding frame 16, and its output shaft is connected to the clamping plate 18. A drill bit movable hole 201 is provided on the support plate 2 along the longitudinal direction. Activating the third servo cylinder 14 can drive the support plate 2 to move longitudinally, thereby adjusting the longitudinal position of the plate. When driving the plate to move continuously to the left, the fifth servo cylinder 17 is activated to drive the plate. The clamping plate 18 moves downward until it clamps the plate. Then, the fourth servo cylinder 15 is activated to drive the U-shaped sliding frame 16 to move to the left to the specified position. The clamping of the plate is then released, and the U-shaped sliding frame 16 is reset by the fourth servo cylinder 15. Repeating the above operation can achieve the leftward translation of the plate. For the rightward translation of the plate, the plate is driven to move in the reverse manner according to a similar method. In this embodiment, the lateral translation of the plate does not rely on the movement of the support plate 2 to drive its movement. Instead, it is driven by the cooperation of the fourth servo cylinder 15, the U-shaped sliding frame 16, the fifth servo cylinder 17, and the clamping plate 18. This ensures that the lateral coordinate position of the milling cutter 9 and the drill bit movable hole 201 is always the same. That is, the milling cutter 9 always moves along the length direction of the drill bit movable hole 201, reducing the opening area on the support plate 2 and thus reducing the dead corners for cleaning.
[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
