Abstract
The utility model discloses a floating piston rod pressure cylinder which comprises a rear end cover, a cylinder barrel, a front end cover, a floating piston rod, a piston rod fixing flange, a piston and an oil cup. The front end cover and the rear end cover are arranged on the two sides of the cylinder barrel in a covering mode respectively, the cylinder barrel is of a hollow structure and a cavity is formed between the front end cover and the rear end cover. The cavity is a pressurization cavity, the piston is located inside the cylinder barrel, one end of the floating piston rod is installed on the piston in a floating mode through the piston rod fixing flange, a gland flange is arranged at one end of the pressurization cavity of the front end cover in a covering mode, the other end of the pressurization cavity of the front end cover is connected with the other end of the floating piston rod in a sleeved mode, the pressurization cavity of the front end cover is matched with the floating piston rod in a sealing mode, a through hole which is communicated with the pressurization cavity is formed in the lateral wall of the front end cover, the oil outlet end of the oil cup is connected with the through hole, and an oil pressure opening communicated with the pressurization cavity is formed in the gland flange. The floating piston rod pressure cylinder is simple in structure and easy to machine, the efficiency is improved, and the problems of leakage and machining difficulty caused by the fact that the pressure cylinder and the piston rod are not concentric are solved.
Description
Technical field
This patent relates to a kind of pressurized cylinder, relates in particular to a kind of piston rod pressurized cylinder.
Background technique
At present, general pressurized cylinder is all that direct piston rod is installed, and the concentricity requirement of piston rod and cylinder barrel is higher, and difficulty of processing is larger, and the probability of leakage of oil is also larger in addition.
Summary of the invention
The purpose of this utility model is in order a kind of floating piston bar pressurized cylinder to be provided, can effectively to solve the problem of pressurized cylinder leakage of oil, reduced processing and assembling difficulty simultaneously, simple in structure, simultaneously supercharging efficiency improves and is easy to and realizes.
The technical solution of the utility model is:
Floating piston bar pressurized cylinder, comprise rear end cover, cylinder barrel, front cover, floating piston bar, piston rod fastening flange, piston, lubricating cup.Front cover and rear end cover are placed on respectively the cylinder barrel both sides, and cylinder barrel is hollow structure, form a cavity between front cover and rear end cover; Described cavity is booster cavity, described piston is positioned at cylinder barrel, floating piston bar one end floats and is installed on piston by the piston rod fastening flange, an end place at the booster cavity of front cover is stamped gland flange, the other end of the booster cavity on front cover is socketed on the other end of floating piston bar, and coordinate with the floating piston rod seal, have the through hole be connected with described booster cavity on the sidewall of described front cover, the oil outlet end of described lubricating cup is connected with through hole, has the force feed mouth communicated with booster cavity on described gland flange.
Lining also is set in front cover, and lining is placed on the floating piston bar.
The external diameter of described floating piston bar is less than the internal diameter of lining, and guarantees floating piston bar and seal with buss.
Described floating piston bar size is less than piston rod fastening flange size, realizes flying height.
Beneficial effect
The utility model is owing to adopting floating piston bar pressurized cylinder, and supercharging efficiency is high, oil-proof, simple in structure.
The accompanying drawing explanation
Fig. 1 is the utility model floating piston bar pressurized cylinder structural representation.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, floating piston bar pressurized cylinder, comprise rear end cover 1, cylinder barrel 2, front cover 3, floating piston bar 6, piston rod fastening flange 7, piston 8 and lubricating cup 9.Front cover and rear end cover are placed on respectively the cylinder barrel both sides, cylinder barrel is hollow structure, form a cavity between front cover and rear end cover, described cavity is booster cavity, described piston is positioned at cylinder barrel, floating piston bar one end floats and is installed on piston by the piston rod fastening flange, and described floating piston bar size is less than piston rod fastening flange size, realizes flying height.An end place at the booster cavity of front cover is stamped gland flange 4, and the other end of the booster cavity on front cover is socketed on the other end of floating piston bar, and coordinates with the floating piston rod seal.In addition, also lining 5 can be set in front cover, lining is placed on the floating piston bar.The external diameter of described floating piston bar is less than the internal diameter of lining, and guarantees floating piston bar and seal with buss.Have the through hole be connected with described booster cavity on the sidewall of described front cover, the oil outlet end of described lubricating cup is connected with through hole, has the force feed mouth communicated with booster cavity on described gland flange 4.
The working procedure of described floating piston bar is: piston 8 is promoted forward by pressurized air, floating piston bar 6 floats and advances in fastening flange 7 and piston 8, oil in lubricating cup 9 enters booster cavity 11 by through hole 10, after floating piston bar 6 passes through filler opening, fluid is sealed in booster cavity 11, start supercharging, booster cavity 11 is by floating piston bar 6, lining 5, gland flange 4 sealings, pressure oil enters operation mechanism by the force feed mouth 12 be located on gland flange 4, pressure ratio is determined by the sectional area of piston 8 and floating piston bar 6, the supercharging discharge capacity is decided by booster cavity 11 volume size, supercharging finishes, and pressurized gas promotes piston 8 return strokes, and floating piston bar 6 also returns, and enters next circulation.
The utility model is not limited to above-mentioned mode of execution; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any change or improvement on the form of rising or structure; every have identical with a application or akin technological scheme, within all dropping on protection domain of the present utility model.
