Abstract
A mechanism for adjusting the inclination angle of a main shaft of a rim roll forming machine comprises a machine body, an upper main shaft module and a lower main shaft module. The upper main shaft module comprises a first eccentric block, a first hinged shaft, a first main shaft and a first incomplete gear, wherein the front end of the first hinged shaft is movably arranged on the machine body through a first knuckle bearing, the rear end of the first hinged shaft is movably arranged on the machine body, and a self-aligning bearing is arranged between a first eccentric sleeve and the first hinged shaft. The front end of the first main shaft is a cantilever end at which a die is installed, and the back end of the first main shaft is connected with a drive oil motor through a first cardan. The eccentric direction of the first eccentric sleeve and the eccentric direction of a second eccentric sleeve are opposite, so that when one of the two eccentric sleeves is driven to rotate, the first eccentric sleeve and the second eccentric sleeve move face to face or back to back at the same time. Two main shafts link and adjust towards the middle at the same time, and the problems that when only one main shaft is adjusted, the included angle is adjusted, the die changes front and back in a displacement mode, and the front forming face and the back forming face are unmatched are solved.
