The utility model solves the problems of the technologies described above adopted technological scheme: a kind of Novel clamping oil cylinder, comprise cylinder body, piston, oil cylinder cylinder cap, also comprise piston gland and piston rod gland, described piston gland is connected by screw II with between piston, be connected by screw III between described piston rod gland with oil cylinder cylinder cap, cylinder efficient pressure can be regulated by adjustment screw II and screw III, connected by screw I between described oil cylinder cylinder cap cylinder body, oil cylinder cylinder cap pressure can be adjusted by screw I after use of exceeding the time limit and continue to use, described piston is provided with the bearing pin perpendicular to piston end surface, described cylinder body is provided with multiple plug screw, piston Sealing is provided with between described piston gland and piston and cylinder body, seal ring is provided with between described oil cylinder cylinder cap and cylinder body, multiple piston rod Sealing is provided with between described oil cylinder cylinder cap and piston rod and piston rod gland, spacer ring is provided with between each piston rod Sealing, cylinder structure design is unique, make the installation of each Sealing, change more convenient, and auto-compensation after wearing and tearing can be realized, reduce the friction factor between each element, guide ring I is provided with between described piston and cylinder body, guide ring II is provided with between described oil cylinder cylinder cap and piston rod, effectively prevent wearing and tearing and scratch.
Further, in such scheme, described piston Sealing is C type slip ring type combined sealing part, and this sealing has long-life, low friction, leak free feature, is highly suitable for hydraulic seal.
Further, in such scheme, described piston rod Sealing is right angle sliding ring assembled seal part, its good seal performance, and corrosion-resistant, and high temperature resistant and low temperature can meet more harsh Environmental Conditions.
Further, in such scheme, described screw I is socket head screw M10X25, and described screw II is socket head screw M5X5, and described screw III is socket head screw M5X8, and socket head screw is convenient to fastening, dismounting, is not easy sliding angle.
Compared with prior art, the beneficial effects of the utility model be embodied in following some:
First, sealing load is high, sealing is adjustable: the cylinder efficient pressure of traditional rubber sealing article design is the highest can only reach 35MPA, cylinder efficient pressure of the present utility model then can be regulated arbitrarily between 0 ~ 70MPA by adjustment screw II and screw III, can adjust oil cylinder cylinder cap pressure continue to use after use of exceeding the time limit by screw I; Use pressure range higher than conventional oil cylinder, can meet more operating conditions, this is not available for conventional oil cylinder simultaneously;
Second, reasonable in design, install, change conveniently: conventional Glais ring needs to use special tool to carry out installing, changing by professional workforce usually, and very easily cause seal ring to damage, and the oil cylinder of the utility model design adopts unique structural design, make the installation of seal ring, change more convenient, without the need to special tool, can be completed by general maintenance man;
3rd, oil cylinder matrix is not easy to wear, scuffing, can reuse: the cylinder structure of the utility model design effectively prevent wearing and tearing and scratches, after seal ring arrives working life, oil cylinder matrix still stands intact, only need change the usability that Xinmi City's seal just can reach new oil cylinder, can reuse and use, greatly reduce cost;
4th, more harsh Environmental Conditions can be met: under conventional cylinder movement state, the highest serviceability temperature is generally 60 ~ 80 DEG C, Efficient lathe oepration at full load oil temperature generally all can remain on about 50 DEG C, therefore can have a greatly reduced quality the working life of conventional oil cylinder, obvious reduction, and the oil cylinder serviceability temperature of the utility model design is-55 DEG C ~ 250 DEG C, meets the usage requirement under extremely low temperature and worst hot case, be obviously better than conventional oil cylinder;
5th, working life is far above conventional oil cylinder: the oil cylinder of the utility model design can realize the rear auto-compensation of wearing and tearing, reduce the friction factor between each element, eliminate conventional oil cylinder friction factor large, easy to wear, seal element easily overturns, plastic cement the phenomenon such as to extrude and the defect such as serviceability temperature scope is little, the working life of oil cylinder is improved greatly, tradition oil cylinder is generally 2 ~ 3 months the working life when lathe running at full capacity, and the oil cylinder of the utility model design reaches 9 months minimum working life, reach 1 year some working life and matrix can reuse, greatly reduce rate of fault and the maintenance frequency of hydraulic chuck, improve equipment operation efficiency, reduce cost of production.
