Press mounting device for one-time mounting of differential bearing of forklift

Abstract

The invention relates to a press mounting device for one-time mounting of a differential bearing of a forklift. The press mounting device comprises an upper platen mechanism and a lower seat mechanism, wherein the upper platen mechanism comprises a vertically corresponding upper base plate, an upper floating platen and more than three upper guide shafts, and the upper platen mechanism is divided into a fixed press head and a floating press head; and the lower seat mechanism comprises a vertically corresponding lower floating base plate, a lower base plate and more than three lower guide shafts, and the lower seat mechanism is divided into a fixed support and a floating support. The press mounting device can finish all press mounting operation of a differential assembly in one working stroke of a hydraulic press; and simultaneously, the press mounting device is provided with a turnover function of the differential assembly with the human assistance.

Description

technical field [0001] The invention belongs to the technical field of process equipment, and in particular relates to a press-fitting device for installing a forklift differential gear bearing. Background technique [0002] There are lower bearings on the lower part of the forklift differential, upper bearings on the upper part, a ring gear and 16 bolts on the upper peripheral surface, and 16 nuts on the lower peripheral surface to be assembled, see image 3 (Picture of pressing in place). In the past, the step-by-step press-fitting process was adopted, that is, the lower bearing was press-fitted first, then the differential case was turned over and the upper bearing was press-fitted, and then the ring gear and bolts were placed on the differential case, and the ring gear was put on. Press-fit the ring gear and its bolt assembly, remove the ring gear presser after pressing, and finally manually carry the differential assembly, turn it over and place it on the pallet. The w...

AI Technical Summary

Problems solved by technology

The existing technical defects are: 1. There are many processes, and seven processes need to be completed in sequence; 2. The labor intensity is high, and unnecessary manual actions such as turning over the differential shell and loading and unloading the pressing tool are required during the press-fitting process; especially the differential assembly is about It weighs 32kg, and the labor intensity of moving and turning over is quite high; 3. It is not safe, the middle of the differential is large and the two ends are small, and there is no unstable positioning on the press table, and there are potential safety hazards in the press-fitting process
