Abstract
A self-rotating oil cylinder comprises an oil cylinder body, an end cover, a piston rod, a transmission shaft and a gear wheel. The transmission shaft is supported on a structural piece sealed with a cylinder body through a bearing, and one end of the transmission shaft extending out of the sealed structural piece is connected with an overturn mechanism of the oil cylinder. The piston rod is a rack shaft, and the portion of the oil cylinder which seals the transmission shaft is provided with a hole meshed by the rack and the gear wheel. The gear wheel is fastened on the transmission shaft part on the sealed rotation oil cylinder body and meshed with the rack shaft on the oil cylinder body at the position of the hole meshed by the rack and the gear wheel. The self-rotating oil cylinder has the advantages that the rack shaft serves as the piston rod, pressure of an oil inlet cavity and an oil outlet cavity of the oil cylinder are identical, and the maximum oil pressure can be achieved before and after overturn of the oil cylinder. The sizes of two ends of the piston rod are the same, the volume of the oil cylinder body is greatly reduced, and using space is lessened. The self-rotating oil cylinder is simple in structure and good in effect, saves equipment and lowers cost. A stop iron structure can be adjusted, accordingly adjustment of stroke of the piston rod is facilitated, and further requirements of each different rotation angle are met.
Description
Technical field:
The utility model relates to machine tool field, relates in particular to the oil cylinder that working machine tool upset material loading is used to use.
Background technique
Oil cylinder is one of parts of the most often using of modular machine tool, and it provides succinct method for the clamping of workpiece, conveying and revolution etc.The flip vertical cylinder structure of existing technology is: hydraulic jack drives driving lever, and driving lever is connected on the axle through key, through axle transmission power, makes feeding device reach the purpose of upset again.The deficiency of existing technology is: when and rotary space that workpiece need less when the lathe space was big, the length of oil cylinder and size tended to cause interference, install and keep in repair also inconvenient simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of small and exquisite stable, and with low cost, oil cylinder is used in simple upset, to overcome the deficiency of existing technology.
The technical solution of the utility model is: a kind ofly be with self-rotating oil cylinder; Comprise oil cylinder part and rotating part; Oil cylinder partly comprises cylinder body, end cap and piston rod, and rotating part comprises transmission shaft, and transmission shaft is sealed on the cylinder body through seal structural part; Transmission shaft passes through bearings on seal structural part; The end that transmission shaft stretches out seal structural part is connected with the oil cylinder switching mechanism, and it is characterized in that: said piston rod is a rack shaft, and the position of sealing transmission shaft has the hole of rack and pinion engagement on the said cylinder body; Said rotating part also comprises gear, and said gear is fastened on the position on the cylinder body that is sealed in of transmission shaft, and place, the hole engagement of the rack and pinion engagement of on cylinder body, offering with rack shaft constitutes the gear rack transmission.
The said a kind of self-rotating oil cylinder of being with of the utility model is characterized in that said end cap is provided with the can regulate buting iron, the can regulate buting iron pass that end cap stretches in the oil cylinder and and end cap between seal.The end of can regulate buting iron outside end cap is screw rod, and screw portion is rotary with adjustment and set screw nut.
The working principle of the utility model is: piston rod is a rack shaft, and piston rod drives transmission shaft through gear and key and rotates in to-and-fro motion, and transmission shaft drives the operation of oil cylinder switching mechanism, makes the oil cylinder upset.Through the residing position of adjustment can regulate buting iron, can finely tune upturned position accurately.
The utility model compared with prior art has following advantage: since with rack shaft as piston rod, the oil suction chamber of oil cylinder is identical with the pressure that goes out oil pocket, guaranteed that oil cylinder upset front and back can reach the effect of maximum oil pressure; Piston rod has not had big or small petiolarea other, so the volume of cylinder body just reduces greatly, usage space diminishes; Simple in structure, saving equipment reduces cost, and is effective; Adopt two ends can regulate buting iron structure, can regulate the stroke of oil cylinder very easily, better controlled the precision of oil cylinder, can realize the demand of each different angles of revolution fully.
