Flexible crane wheel assembly line

Abstract

The invention discloses a flexible crane wheel assembly line which comprises a first station area, a second station area and a third station area, wherein the first station area is in charge of completing press fitting of wheels and wheel axles; the second station area is in charge of completing press fitting of corner boxes and bearing outer rings; and the third station area is in charge of completing press fitting or assembly of the wheels subjected to press fitting in the first station area, the corner boxes and bearing outer rings and accessories thereof subjected to press fitting in the second station area, as well as running-in test of finished products. Compared with the prior art, the flexible crane wheel assembly line disclosed by the invention mainly comprises three presses, two rollaway nests and other auxiliary equipment, the axles and wheels are subjected to press fitting together in the first station and can be transferred into the third station by the rollaway nests, and accessories such as through covers, spacer bushes and the like can be assembled on the rollaway nests; the corner boxes and bearing outer rings are subjected to press fitting together in the second station, the two bearing outer rings can be simultaneously pressed in, the bearings and bearing boxes are assembled on the wheels in the third station, and the accessories such as through covers, valve covers, standard fasteners and the like are assembled after press fitting completion.

Description

technical field [0001] The invention belongs to the technical field of crane wheel assembly, and in particular relates to a flexible assembly line for crane wheels. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range, also known as a crane, and belongs to material handling machinery. The working characteristic of the crane is to do intermittent movement, that is, the corresponding mechanisms for the actions of retrieving, moving, and unloading in a working cycle work alternately. The development and use of cranes in the market are becoming more and more extensive. [0003] At present, the crane wheel assembly mainly adopts horizontal assembly. The wheel is laid flat, the shaft is pressed in, and the bearing is heated at the same time. Part of the outer ring of the bearing is put into the bearing box by continuous tapping with copper rods. Dimensional accuracy is d...

Problems solved by technology

[0003] At present, the crane wheel assembly mainly adopts horizontal assembly. The wheel is laid flat, the shaft is pressed in, and the bearing is heated at the same time. Part of the outer ring of the bearing is put into the bearing box by continuous tapping with copper rods. Dimensional accuracy is difficult to guarantee accurately

If a horizontal assembly line is used (the wheels are placed flat), the transfer and turning of the wheels are both problems
