Description
Technical field
The utility model relates to a kind of piston rod rotation cylinder flexibly.
Background technique
The lathe that automaticity is higher need control the folding of fixture with cylinder, with clamping workpiece, piston rod need be driven to rotate together when fixture rotates, general cylinder piston rod frequently rotates the working life greatly reducing Sealing.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides a kind of piston rod rotation cylinder flexibly, can not cause the wearing and tearing of Sealing during the piston rod rotation of this cylinder.
The utility model solves the technological scheme that its technical problem adopts: a kind of piston rod rotation cylinder flexibly, comprise the cylinder body that one end is closed, be arranged on the piston in cylinder body, be fixed on the cylinder cap of the cylinder body the other end, described piston two ends have the shaft extension portion of stretching out cylinder body closed end and cylinder cap respectively, center, shaft extension portion is provided with the piston rod mounting hole running through diaxon extending portion and piston, the piston rod be flexibly connected with piston rod mounting hole is provided with in piston rod mounting hole, piston rod one end is provided with the center tapped blind hole for being connected with machine tool fixture, described diaxon extending portion free end is respectively equipped with bearing hole, the angular contact ball bearing with dust cover for support piston bar is separately installed with in diaxon bearing bore, piston rod is connected with piston rotation by these two angular contact ball bearings.
Described piston shaft extending portion is cylindrical, described cylinder body closed end and cylinder cap are respectively equipped with match with shaft extension portion and the central through bore be flexibly connected, be provided with seal ring between central through bore inwall and shaft extension portion, cylinder body closed end and cylinder cap are also respectively equipped with the porting communicated with inner chamber of cylinder block.
The beneficial effects of the utility model are: piston rod of the present utility model is connected with piston rotation by two angular contact ball bearings, can not cause the wearing and tearing of cylinder inner seal liner when thus piston rod rotates with machine tool fixture when cylinder does not rotate.
