Description

Adjustable roller supporting device

Technical Field

The utility model belongs to the technical field of axle type part machining auxiliary fixtures, especially, relate to a gyro wheel strutting arrangement with adjustable.

Background

For large shaft parts, indexing is often required in the machining process so as to machine keyways at different circumferential positions of the outer circle of the shaft. For example, three key grooves for mounting key blocks are uniformly distributed on the outer circles of the two ends of the central pivot of the excavator along the circumferential direction, when the key grooves are machined, two pieces of V-shaped iron are used as positioning tools to support the two ends of the central pivot, and after machining of one key groove is completed, the central pivot needs to be rotated to the next key groove machining position. Thus, the machining of all three keyways of the center pivot requires at least two rotations of the center pivot. The weight of large shaft parts such as the center pivot of the excavator is large, for example, the center pivot of the excavator has the dead weight of about 5 tons, and the friction force between the center pivot and the V-shaped iron must be overcome by manually rotating the center pivot, so that the time and the labor are wasted; relying on the crane to drag to rotate the central pivot would increase the cost of the equipment and would not provide precise positioning angles.
