Abstract
The utility model provides a mechanism arranged on a rim roll forming machine and used for adjusting the inclined angle of a main shaft. The mechanism 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. The front end of the first hinged shaft is movably connected to the machine body through a first knuckle bearing. The rear end of the first hinged shaft is movably connected to the machine body. A self-aligning bearing is arranged between a first eccentric shaft sleeve and the first hinged shaft. The front end of the first main shaft is a cantilever end for installing a mould. The rear end of the first main shaft is connected with a driving oil-motor through a first cardan joint. The eccentric direction of the first eccentric shaft sleeve is opposite to the eccentric direction of a second eccentric shaft sleeve, so that the first eccentric shaft sleeve and the second eccentric shaft sleeve simultaneously move in the opposite directions or in the back-to-back directions. The two main shafts are in linkage with each other and can be simultaneously adjusted towards to the middle position. The phenomenon that the front and back displacement of a mould changes to cause the condition that a front molded surface does not accord with a rear molded surface when only one main shaft and the included angle are regulated is effectively prevented.
