[0028] When the irregular hardware processing center is used to process the irregular hardware, the following steps are included: S1: The front end, upper end and one side end of the irregular hardware are set to be the A side, the B side and the C side respectively. The opposite sides of the front end, upper end and one side end of the irregular hardware are set to be the D side, the E side and the F side respectively. When the side that does not need to be processed is an adjacent side, in one embodiment of the present invention, the adjacent side is set to be the DE side, but is not limited to the DE side. At this time, the two rotating ball assemblies 32 apply pressure to the A side and the D side respectively and limit the clamping of the irregular hardware. The processing structure of the machining center body 1 first processes the B side. After the B side is processed, the meshing wheel 505 is driven to rotate by the second motor 504.

In this process, the pressure direction change generated when the rotating ball assembly 32 moves from the A surface to the E surface is overcome by the adsorption force generated on the D surface, so that the processing process of the F surface can still be in a stable state. Then, the hydraulic push rod 3302 drives the air collecting ring 3303 to move, and the vacuum suction cup 3307 can adsorb the E surface of the irregular hardware under the action of the vacuum generator 3304; S3: Then disconnect the vacuum generator 3304 on the vacuum suction cup 3307 on the D surface, and retract the vacuum suction cup 3307 on the D surface through the hydraulic push rod 3302, so that only the elastic ball cover 3205 is pressed on the D surface, and then drive the roller frame 4102 connected to the fixed ring 501 to rotate through the second motor 504. When the central axis of the fixed roller 4101 is perpendicular to the lead wire of the moving direction of the irregular hardware, stop the second motor 504, and drive the second synchronous wheel 4105 to rotate through the third motor 4106, so that the second synchronous wheel 4105 synchronously drives the first synchronous wheel 4103 and the synchronous belt 4104 to rotate, so that the fixed roller 4101 rotates around its own central axis, so that the fixed strip 4204 connected to the fixed roller 4101 can move the bottom of the hardware, so that the A surface can be located at the lower end of the machining structure of the machining center body 1, so as to realize the machining of the A surface and complete the surface machining of the irregular hardware; The whole process can achieve uninterrupted processing, and during the whole uninterrupted processing process, the limit clamping of the irregular hardware is in a stable state, which is not only suitable for irregular hardware of different specifications and shapes, but also can effectively improve the processing efficiency.
