[0048] Figure 4 A three-dimensional schematic diagram showing the rotary base according to some embodiments of the present cantilever rotary processing device is presented. In some embodiments, the rotary base 2 includes a rotary bearing. The rotary bearing includes a rotary bearing inner ring 21 and a rotary bearing outer ring 22. The rotary bearing inner ring 21 is fixedly connected to the base 1, and the rotary bearing outer ring 22 is sleeved on the outer periphery of the rotary bearing inner ring 21 and is rotatable relative to the rotary bearing inner ring 22.

[0054] In some embodiments, as Figure 6 shown, a positioning opening 500 is formed in the positioning portion 50. The positioning opening 500 can be engaged with the slider 4 to restrict the movement of the slider 4. When the device performs a drilling operation, the positioning portion 50 is clamped to the slider 4 to achieve the stability of the drilling operation.

[0055] In a specific embodiment, as Figure 9 shown, the support assembly 6 further includes a support body 61. A pair of pulleys 60 are arranged on a cage 62. The cage is hinged to the support body 61, so that the pulley 60 has a certain degree of rotational freedom relative to the support body 61, so as to achieve balanced force support of the two pulleys 60 on the flange plate during milling of the plane, ensuring that the processing unit installed on the slider can stably perform processing.

[0056] As Figure 1 shown, the slider 4 includes a first sliding member 41 and a second sliding member 42. Figure 7 shows a three-dimensional schematic diagram of the first sliding member according to some embodiments of the present cantilever rotary processing device.

[0059] Figure 10 The schematic diagram when the cantilever rotary machining device provided by some embodiments of the present application performs a milling plane operation is shown. First, the drum flange 90 is lifted to the machining equipment accessory and placed on the stepped plane of the flange fixture. After adjusting the levelness of the drum flange, the drum flange is fixed by using the flange fixture. Then, the sliding support is moved to the upper surface of the flange, the electric spindle cutter head on the machining components is replaced with a milling cutter, and after starting the electric spindle, it rotates through the stepping electric drive device, the milling cutter horizontally moves through the servo motor on the cantilever component 3, and rotates 360 degrees around the cantilever component 3 to realize the machining of the whole circumferential direction of the material.

[0060] Figure 11 The schematic diagram when the cantilever rotary machining device provided by some embodiments of the present application performs a drilling operation is shown. During the drilling operation, the electric spindle cutter head on the machining components is replaced with a drill bit, the positioning support is slid to the inner ring of the flange 91, the positioning fixture of the positioning support is clamped to the flange 91 through bolts, rotates through the stepping electric drive device, the drill bit horizontally moves to the scribed drilling point through the servo motor on the cross beam, after starting the electric spindle, it is driven by the servo motor on the cantilever component 3 to make the machining component vertically move downward until the hole machining is completed, and rotates 360 degrees around the cantilever component 3, and repeats the operation to machine all the holes on the drum flange.

[0061] The cantilever rotary machining device with this configuration can easily move the machining unit to any circumferential position of the workpiece to be machined by rotating the cantilever 360 degrees. At the same time, by setting the positioning component and the support component, during processes such as drilling and milling the plane, the stability of the machining process of the machining unit can be ensured through the positioning component and the support component, so that it is not necessary to change the position of the workpiece, and the stable machining of the whole circumferential direction of the rotary workpiece can be realized by using the same equipment, improving the machining efficiency.
