The invention provides a heavy-load cross supporting mechanism. The mechanism comprises a cross supporting body, a bearing sleeve and a positioning locking sleeve; the bearing sleeve comprises a connecting ring and a sleeve body arranged on the left side of the connecting ring; the sleeve body, the connecting ring and the positioning locking sleeve are sequentially sleeved on a tailstock sleeve of a lathe from left to right, the connecting ring and the positioning locking sleeve are fixedly connected through bolts, and the positioning locking sleeve is fixed on the tailstock sleeve, so that axial positioning of the bearing sleeve is realized; the cross supporting body comprises a middle supporting ring and an outer supporting ring, a plurality of supporting plates are arranged between the middle supporting ring and the outer supporting ring, a plurality of supporting devices with adjustable lengths are arranged on the outer supporting ring, and the middle supporting ring is arranged on the sleeve body through a bearing assembly; and the bearing assembly comprises a roller bearing and a thrust bearing, the roller bearing and the thrust bearing are arranged on the sleeve body, and the roller bearing is positioned on the left side of the thrust bearing. The mechanism can be used on large-scale hollow pieces with weight of 50 tons or above, radial force can directly act on the tailstock sleeve, so that the tailstock sleeve can be prevented from bearing large radial force torque and axial force.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to a heavy-duty cross support mechanism. Background technique [0002] For large hollow parts over 50 tons, it is difficult to support the rotation of the workpiece with the common cross brace and the tip of the tailstock of the lathe. The workpiece is supported by the tip of the tailstock. Because the workpiece is relatively heavy, the tip bears a large radial force and axial force , the friction force is large, and the tip is prone to heat and damage, which affects the processing of hollow parts. [0003] CN207272813U discloses a large-diameter furnace roller processing and locking cross support device, including a middle support block, a number of support columns evenly distributed on the outer circle of the middle support block, and the ends of the support columns are provided with holes for controlling and large-diameter furnace rollers. The adjustment device for the distanc...
