Abstract
The utility model relates to the oil cylinder manufacturing industry, in particular to a special pre-tightening lever oil cylinder. The oil cylinder consists of a rear cover, an oil cylinder base, a rectangle spring, a piston, a clamping plate, a hinge and a plurality of groups of sealing dust-proof mechanisms, wherein the rear cover is connected with the oil cylinder base through a fastener, the rectangle spring is installed inside the piston, and the clamping plate and the hinge are installed on the piston. The oil cylinder has the advantages that different clamping forces of an identical oil cylinder, an identical oil duct and identical oil pressure are output twice. The production-manufacturing cost of the frock clamp is greatly saved.
Description
Technical field:
The utility model relates to the oil cylinder manufacturing, is specially a kind of special-purpose precompressed compact form lever oil cylinder.
Background technique:
Under the present circumstances, require workpiece is hanged down earlier the pre-clamping of clamping force in many jig Design, and then workpiece is located normally, at last the workpiece high-clamping force is clamped.At present jig Design realizes twice pressure output of same clamping cylinder or two groups of oil circuits are realized same clamping cylinder by valve members such as pressure-limit valve, one-way valves twice pressure output by two groups of solenoid valves in the hydraulic station and two groups of oil circuits substantially.There is following defective in above-mentioned dual mode: 1) to the having relatively high expectations of hydraulic station, need to be made up of many groups oil circuit and hydrovalve, solenoid valve etc., the cost of hydraulic station improves.2) hydraulic pressure original paper number is more, and it is big wrong probability to occur.3) oil circuit of the fixture in the built-in anchor clamps is more, and processing cost and difficulty are bigger.
Summary of the invention:
The purpose of this utility model provides a kind of special-purpose precompressed compact form lever oil cylinder, thereby has overcome the deficiency of existing lever oil cylinder.
Technical solution of the present utility model is: a kind of special-purpose precompressed compact form lever oil cylinder, by bonnet, oil cylinder pedestal, rectangle spring, piston, pressing plate and hinge with organize sealing and dustproof mechanism more and form, bonnet links to each other by fastening piece with the oil cylinder pedestal, the rectangle spring is contained in internal piston, and pressing plate and hinge are contained on the piston.
The beneficial effects of the utility model: realize the output of twice different clamping force of same oil cylinder, same oil circuit, same oil pressure.Saved the manufacturing cost of frock clamping greatly.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Fig. 1 the utility model structural representation
1. bonnets among the figure, 2. oil cylinder pedestal, 3. rectangle spring, 4. piston, 5. pressing plate and hinge
Embodiment:
In Fig. 1, bonnet (1) links to each other by fastening piece with oil cylinder pedestal (2), and rectangle spring (3) is contained in piston (4) inside, and pressing plate and hinge (5) are contained on the piston (4).
Concrete working principle: this special-purpose precompressed compact form lever oil cylinder adopts standard Lever type oil cylinder structure commonly used, and different is that this oil cylinder piston (4) afterbody has a blind hole, positioned inside one rectangle spring (3).When this oil cylinder passes through a sequence valve series operation with other hydraulic element, because the built-in rectangle spring (3) of this oil cylinder, this oil cylinder can carry out prestressing work prior to other hydraulic element when same oil circuit oil-feed, thereby and itself does not have hydraulic oil to enter cylinder body to export a lower impacting force this moment.After other hydraulic element oil-feeds finished, sequence valve is opened this moment this oil cylinder had hydraulic oil to enter in the cylinder body, the high clamping force of output one under the effect of hydraulic oil, thus realize the output of twice different clamping force of same oil circuit, same oil pressure.
Claims (1)
1. special-purpose precompressed compact form lever oil cylinder, by bonnet, oil cylinder pedestal, rectangle spring, piston, pressing plate and hinge with organize sealing and dustproof mechanism more and form, it is characterized in that: bonnet links to each other by fastening piece with the oil cylinder pedestal, and the rectangle spring is contained in internal piston, and pressing plate and hinge are contained on the piston.
