Abstract
The utility model relates to a guide shaft for a rotary clamping cylinder. The guide shaft and a groove in a guide post in the cylinder move in a matching mode, and the guide shaft for the rotary clamping cylinder is characterized in that the guide shaft has an elliptical cylinder structure of which the cross section is gradually reduced; the axial far-end cross section of the guide shaft is gradually reduced; and the guide shaft is made of a high polymer material phenolic resin or a high-hardness corrosion-resistant metal material. A contact surface between the guide shaft and the groove can be effectively enlarged, the guide shaft flexibly rotates and has high rigidity, and the service life of the guide shaft is prolonged.
Description
Technical field
The utility model relates to a kind of hydraulic rotating fastening device, particularly a kind of axis of guide that is used for the rotating clamp locking oil cylinder.
Background technique
At present, the formed fastening device of rotating clamp locking oil cylinder is widely used in being used in particular for the machine-building of heavy parts in the technology such as machine-building, accurate detection, robot; Because rotating clamp is critical asks rotation comparatively flexible, rotating machinery often moves, and in the rotation fastening device, originally the axis of guide of design is a cylindrical body; It mainly acts on is guiding and location, in corresponding groove, moves good rigidly; Low cost of manufacture, but it in use is prone to the generation obstruction at groove in the corner, cause and rotate dumb even the generation stuck phenomenon; At operation field since in the stove temperature high, handles untimelyly, be prone to the generation security incident; Conventional method is to change the axis of guide, but the frequency of changing is very fast, and must dismantle liquid cylinder entity.Workload is bigger, and behind the axis of guide after changing working life not high.Shape through for groove is improved; But also can't tackle the problem at its root, subsequently the shape of the axis of guide improved, change the axis of guide into cone; But in use produce phenomenon of rupture through the circular cone place that is everlasting, analyzing reason is because the rigidity here is too poor.
The model utility content
In order to overcome the above-mentioned deficiency of existing technology, the utility model provides a kind of rotating clamp locking oil cylinder to use the axis of guide, and the utility model can effectively increase the surface of contact of groove, and rotates flexibly, and the axle rigidity is strong, improves working life.
The utility model is realized through implementing following technical proposals:
A kind of rotating clamp locking oil cylinder is used the axis of guide, and the groove in the said axis of guide and the oil cylinder inner guiding post carries out routing motion, it is characterized in that the said axis of guide is the diminishing cylindroid body structure of cross section.
The said axis of guide reduces to distal cross section gradually.
The said axis of guide is made up of the metallic material of macromolecular material phenolic resin or high-hardness corrosion-resistant.
The utility model can effectively increase the surface of contact of the axis of guide and groove, and rotates flexibly, and the axle rigidity is strong, improves working life.
