Abstract

The invention relates to a press fitting device for one-step mounting of a hub bearing of a forklift truck. The device comprises a base plate, a positioning shaft, a lower bearing pressing block, a floating plate, a guide mechanism, an upper bearing pressing block and a bolt pressing sleeve, wherein the guide mechanism comprises four guide shafts; a compression spring is sleeved on each guide shaft; a limiting block is arranged at the upper end of each guide shaft through a screw; a ring-shaped conical platform is arranged at the upper part of the lower bearing pressing block and is contacted with the inner conical surface of a lower bearing; a ring-shaped conical platform is arranged at the upper part of the upper bearing pressing block; a transitional step is arranged on the circumference of the lower end; the conical platform is matched with an inner hole of an upper bearing; the bolt pressing sleeve is ring-shaped; six axial blind holes are distributed on the circumference of the bottom of the bolt pressing sleeve uniformly; and each blind hole is matched with the corresponding bolt press fitting end on a hub. The device finishes the press fitting of the hub component by one step, so the work efficiency is increased by three times, manual turnover is reduced and the labor intensity is reduced; and a workpiece is positioned before press fitting, so the press fitting process is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of mechanical production process equipment, and in particular relates to a press-fitting device for installing fork wheel hub bearings. Background technique [0002] There are lower bearings and upper bearings at both axial ends of the fork wheel hub, and there are 6 bolts on the circumference; the existing installation method is to press-fit one by one, that is, press-fit the lower bearing first, then turn the hub over, and then press-fit it. For the bearing, 6 bolts are finally pressed. The whole process needs to be pressed three times and turned over once. The defects of the existing technology are as follows: 1. There are many processes: four processes are required to complete the installation of the lower bearing, the upper bearing and 6 bolts; 2. The labor intensity is high: the workpiece needs to be turned over manually during the press-fitting process; 3. Safety: The hub is placed flat on the press ...
