Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figures 1-6 As shown, the boom in this embodiment uses an automated milling fixture to clamp the boom 100. The boom 100 has an inner hole 101 in the middle and is mainly composed of a worktable 10, multiple pressing units 20, multiple floating support units 30, multiple lifting units 40, and a positioning unit 50. The pressing units 20, floating support units 30, and lifting units 40 are all distributed along the outer trajectory of the boom 100. The positioning unit 50 is located at the center of the boom 100 to achieve positioning and clamping of the boom 100. The operation of the above units is controlled by a solenoid valve.

[0031] Specifically, the pressing unit 20 is rotatable and used to press against the upper end of the boom. The pressing unit 20 includes a corner cylinder 21, a pressure plate 22, and a pressure rod 23. The output end of the corner cylinder 21 is connected to the pressure plate 22, the pressure plate 22 is connected to the pressure rod 23, and the pressure rod 23 is in contact with the boom. The corner cylinder 21 is used to drive the pressure plate 22 to rotate and rise and fall.

[0032] The floating support unit 30 is used to abut against the lower end of the boom. The floating support unit 30 is a conventional support cylinder structure in the field, and no further limitations are made here. It can achieve floating support.

[0033] Accordingly, the lifting unit 40 abuts against the lower end of the boom and is used to lift the boom. The lifting unit 40 includes a lifting cylinder, such as a cylinder, and a push rod. The push rod is connected to the output end of the lifting cylinder and is in contact with the boom.

[0034] Additionally, the positioning unit 50 can contract and expand to abut against the inner hole 101. The positioning unit 50 includes a positioning cylinder 51, a support sleeve 52, an expansion shell 53, and a movable body 54. The movable body 54 is connected to the output end of the positioning cylinder 51. The support sleeve 52 is sleeved on the movable body 54 and located inside the expansion shell 53. The movable body 54 can move within the expansion shell 53 and drive the expansion shell 53 to contract or expand. The support sleeve 52 is embedded in the expansion shell 53, which can prevent the movable body 54 from continuing to move downward, thus achieving a limit.

[0035] The expansion shell 53 includes a main ring body 531, which is fixedly connected to the worktable 10. The main ring body 531 is provided with a plurality of claw plates 532, and there is a gap between two adjacent claw plates 532. The claw plates 532 are in contact with the movable body 54.

[0036] The movable body 54 includes a main rod 541, with a contact block 542 at the top of the main rod 541. The contact block 542 has a first inclined surface, and the claw plate 532 has a second inclined surface on its inner side. The first inclined surface and the second inclined surface are in contact and cooperate, that is, the contact block 542 is generally in the shape of a frustum, and the inner side of the claw plate 532 also forms a frustum structure, which facilitates smooth contact between the two. The claw plate 532 expands outward by the pressure of the contact block 542, thereby pressing the rod 100 tightly.

[0037] In use, the lifting rod 100 is first placed in the corresponding position on the workbench 10. The positioning unit 50 expands and presses against the inner hole 101 of the lifting rod 100 to achieve positioning and clamping. Then, the floating support unit 30 adjusts the flatness of the lifting rod 100. Then, the pressing unit 20 presses down to contact the lifting rod 100. Then, the lifting unit 40 lifts the lifting rod 100 to achieve clamping from both the top and bottom. Then, the inner frame of the lifting rod 100 is milled by the machine tool until the inner frame is finished. Then, the outer side is milled. Before the cutting tool reaches the pressing unit 20 in the corresponding position, the pressing unit 20 rotates away from the cutting tool's machining path to avoid interference. After the machining of this position is completed, the pressing unit 20 returns to its original position until the outer shape is finished.
