The purpose of this utility model is to provide a kind of locking cylinder with automatic fastening function, and it has the feature of auto lock, to solve the problems referred to above that in prior art, locking cylinder exists.
For reaching this object, the utility model by the following technical solutions:
A kind of locking cylinder with automatic fastening function, it comprises gland, cylinder barrel, cylinder bottom, piston and piston rod, described gland and cylinder bottom are individually fixed in the two ends of described cylinder barrel, described piston rod penetrates in described cylinder barrel and its middle part is provided with piston, between described piston and inner wall of cylinder, pass through piston seal component sealing, on described cylinder barrel, offer the hydraulic fluid port of unblanking, wherein, on described piston rod, between piston and cylinder bottom, be superimposed with several precompressed butterfly springs, described precompressed butterfly spring elastic-restoring force is not less than the coupling mechanism force of locking cylinder.
Especially, the end of described piston rod is fixed with latch by fixing bolt.
Especially, one end that gland is set in described cylinder barrel is provided with guide sleeve, and the rod end that described guide sleeve is inserted in piston rod packs in cylinder barrel, and described gland is by guiding casing pressure and be fixed on one end of cylinder barrel.
Especially, on described cylinder bottom, be provided with endoporus, in described endoporus, be equipped with the rear guide pin bushing that piston rod is played to support guide effect, and described cylinder bottom outside is fixed with bonnet by fixing bolt.
Especially, between the rod end of described piston rod and guide sleeve and cylinder barrel, by rod seal assembly, seal.
The beneficial effects of the utility model are that compared with prior art the described locking cylinder with automatic fastening function has the following advantages:
1) on described piston rod, between piston and cylinder bottom, be superimposed with several butterfly springs, butterfly spring group is carried out to a certain amount of precompression, make the elastic-restoring force of butterfly spring group reach the coupling mechanism force of locking cylinder, make elastic-restoring force can replace part hydraulic coupling, guaranteed that locking cylinder can run well under the abnormal conditions such as electric equipment to have guaranteed the normal operation of whole production line.
2) after employing rod end combination seal, reduce frictional force, improved sealing.
