Description

A large tapered roller bearing pillar cage welding elevation indexing machine

technical field

The utility model relates to the field of bearing manufacturing, in particular to an elevation indexing machine for welding a pillar cage of a large tapered roller bearing.

Background technique

Due to the existence of the pressure angle of the large tapered roller bearing, the molten iron will flow down to the lower part due to the action of gravity during the welding process of the pillar cage, which will cause the defects of irregular shape and poor quality of the solder joints. Can not meet the process requirements. And it is easy to open welding during use, causing early damage to the bearing.

Utility model content

The purpose of this utility model is to provide a large-scale tapered roller bearing pillar cage welding elevation angle indexing machine in order to improve the welding quality of the tapered roller bearing pillar cage and prolong the service life of the bearing. Using this machine can make each welding The centerlines of the pillars are vertical to the ground, and this device can adjust the angle according to the bearings of different angles.

The technical solutions adopted are:

A large-scale tapered roller bearing pillar cage welding elevation indexing machine, including a base, a Y-shaped tripod worktable, a top block, an indexing slewing support bearing outer ring, an indexing slewing support bearing inner ring, a slewing drive shaft, and a slewing gear , Swivel sprocket, angle adjustment seat plate, angle adjustment bracket, geared motor. The Y-type tripod workbench is equipped with bearing inner components, and is fixed on the Y-type tripod workbench with a top block. The inner ring of the indexing slewing support bearing is the inner ring of the indexing slewing support bearing with internal teeth, the Y-shaped tripod worktable is fixedly connected to the inner ring of the indexing slewing support bearing, and the lower left corner of the outer ring of the indexing slewing support bearing is fixed by The rotating shaft on it is hinged with the holes of the earrings fixed on both sides of the base, which can make the outer ring of the indexing slewing support bearing rotate; The hinged seat on the base is hinged, and the angle is adjusted through the screw nut shaft, sleeve and hexagon nut installed on the angle adjustment bracket, so that the center line of the welded pillar is vertical to the ground. The middle part of the outer ring of the indexing slewing support bearing is connected to the angle adjustment seat plate, the reduction motor is installed on the outer end of the angle adjustment seat plate, the two ends of the rotary drive shaft are respectively installed with a rotary gear and a rotary sprocket, and the rotary drive shaft passes through the bearing seat Supported on the angle adjustment seat plate, the rotary gear meshes with the internal teeth of the inner ring of the indexing rotary support bearing, the rotary sprocket is connected to the sprocket mounted on the output shaft of the deceleration motor through the chain, and the deceleration motor passes through the sprocket, chain, and rotary sprocket And the slewing gear drives the inner ring of the indexing slewing support bearing to rotate, so that the pillars welded each time are all directly above.

The utility model has the advantages that the quality of the bearing is guaranteed, the production efficiency is improved, and the service life of the bearing is prolonged.
