Figures 1-4

[0029] The casing fixing mechanism comprises an overturning and holding up assembly 21 arranged at the upper middle part of the machine table 10 for supporting the casing, a rotary drive assembly 22 arranged at one side of the machine table 10 for fixing the casing and driving the casing to rotate, and a steady guide assembly arranged above the overturning and holding up assembly 21.

[0030] ​The shaving and milling mechanism 30 comprises a telescopic driving assembly 31 arranged on the other side of the machine table 10, and a shaving and milling tool 32 arranged on the telescopic driving assembly 31 and used for performing step processing on the inside of the machine shell.

[0031] Based on the above scheme, in the specific implementation process, the overturning and lifting assembly 21 is first controlled to be in a horizontal state, the operator places the machine shell to be processed above the overturning and lifting assembly 21, then the machine shell is locked on the rotary driving assembly 22 through the bolts 40 (after this action is completed, the overturning and lifting assembly 21 is reset), then the stable guiding assembly is lowered to contact the upper surface of the machine shell, and finally the telescopic driving assembly drives the shaving and milling tool 32 to extend into the inside of the machine shell and controls the rotary driving assembly 22 to drive the machine shell to rotate. In this process, the shaving and milling tool 32 starts to perform shaving and milling processing on the machine shell.

[0032] In one specific embodiment, the overturning and lifting assembly 21 of the present application comprises two first vertical plates 211 arranged above the machine table 10, an overturning table 214 hingedly connected between the two first vertical plates 211 through a rotating shaft 212, a U-shaped block 215 arranged on the overturning table 214, and a speed reducer motor 213 arranged on one side of one of the first vertical plates 211 and connected with the rotating shaft 212. Before the operator installs the machine shell with the rotary driving assembly 22, the high-speed motor 213 is controlled to drive the rotating shaft 212 to rotate until the overturning table 214 is in a horizontal state, and then the operator places the machine shell in the U-shaped block 215. At this time, the operator can fix the machine shell with the rotary driving assembly 22 through the bolts 40. Compared with the traditional method, the operator is avoided to lift, and the installation difficulty with the rotary driving assembly 22 is reduced.

[0033] In one specific embodiment, the rotary driving assembly 22 of the present application comprises a second vertical plate 221 arranged on one side of the machine table 10, a high-speed motor 222 arranged on the second vertical plate 221, a rotary carrier 223 connected with the output shaft of the high-speed motor 222 on one side of the second vertical plate 221, and a plurality of locking holes 224 arranged in an annular array on the rotary carrier 223. In the specific implementation, the operator screws a plurality of bolts 40 through the machine shell into the locking holes 224, and the rotary carrier 223 can be driven to rotate when the high-speed motor 222 operates.

[0034] In one of the specific embodiments, the stable guiding assembly of the present application comprises an inverted L-shaped frame 231 erected on the machine table 10 and opposite to the overturning and lifting assembly 21, a lifting driving cylinder 232 arranged on the transverse part of the inverted L-shaped frame 231, a carrier plate 233 connected below the piston rod of the lifting driving cylinder 232, two mounting grooves (not labeled) opened on the carrier plate 233 and two guiding rollers 234 rotatably mounted in the two mounting grooves. After the machine shell is mounted on the rotary driving assembly 22, the lifting driving cylinder 232 is controlled to drive the carrier plate 233 to descend until the two guiding rollers 234 contact the machine shell from both sides. In this way, when the rotary driving assembly 22 drives the machine shell to rotate, the machine shell will not shake, thereby ensuring the machining quality of the steps in the machine shell.

[0035] In one of the specific embodiments, the telescopic driving assembly 31 of the present application comprises a telescopic driving cylinder 314, two linear guides 311 arranged side by side on the machine table 10, a sliding table 312 slidingly connected on the two linear guides 311, and a connecting block 313 arranged on the bottom of the sliding table 312 and connected with the piston rod of the telescopic driving cylinder 314. Before machining the steps in the machine shell, the telescopic driving cylinder 314 drives the connecting block 313 to extend with the sliding table 312 until the milling cutter 32 extends into the interior of the machine shell and contacts the inner side wall of the machine shell.

[0036] Specifically, the milling cutter 32 of the present application is fixed on the sliding table 312 by bolts 40 and extends towards the rotary driving assembly 22.

[0037] In order for the telescopic driving cylinder 314 to drive the sliding table 312 to move to the set position, the present application is provided with a stop block 315 on the machine table 10 corresponding to one side of the sliding table 312, and a contact block 316 is arranged on one side of the sliding table 312 and matched with the stop block 315. When the contact block 316 on the sliding table 312 contacts the stop block 315, the telescopic driving cylinder 314 stops driving the sliding table 312 to slide, at this time, it indicates that the milling cutter 32 has reached the set position.
