Abstract
The utility model discloses a solid-interior single-piston pressure-maintaining rotary oil cylinder, comprising a cylinder body (10), an oil distribution valve stem (20) mounted on the cylinder body (10), and an oil distribution valve body (21) and a bearing (30) which are mounted on the oil distribution valve stem (20). An adjusting gasket (22) is arranged between the oil distribution valve body (21) and the oil distribution valve stem (20). A link rod piston (40) which is solid is mounted in the central parts of the cylinder body (10) and the oil distribution valve stem (20). The cylinder body (10) is also inwardly provided with a pressure-maintaining valve (50). The solid-interior single-piston pressure-maintaining rotary oil cylinder provided by the utility model is advantaged by being high in oil cylinder rotating speed, large and stable in output force, and good in safety performance simultaneously.
Description
Technical field
The utility model relates to field of machining, particularly the single piston pressurize of a kind of middle reality angling cylinder.
Background technique
The hydraulic gyration oil cylinder is the accessory of a fitting tight, it uses hydraulic pressure in very little space, gathered very high moment of torsion, usually be applied on the mechanical processing machine, clamping in particular for the part of machine tooling provides clamping force, can provide at any time clamping force or unclamp when clamping processing accessories, operation is very easy.Existing angling cylinder is owing to the reason of this body structure, there is the gap between oil distributing valve body and the oil distributing valve bar, this gap can not be controlled artificially, so that the loss of the oil pressure in the angling cylinder cylinder body is difficult to be controlled, oil pressure is not enough in the cylinder body, causes link rod piston rotating speed excessively low, the push-pull effort of output is less or unstable, to machining workpiece clamp reliable not, affect course of working, reduced work efficiency.In addition, when carrying out machining operation, if suddenly outage of lathe or pressure source are in the situation that suddenly interruption in the pressure process gets loose part just angling cylinder can quit work, Safety performance is lower.
The model utility content
The purpose of this utility model provides the single piston pressurize of a kind of middle reality angling cylinder, and it is high that it has an oil cylinder rotating speed, and High power output and stable has advantages of also that simultaneously Safety performance is high.
In order to realize this purpose, the technical solution adopted in the utility model is as follows: the single piston pressurize of middle reality angling cylinder, it is characterized in that, it comprises cylinder body, be installed on the oil distributing valve bar on the cylinder body, and be installed on oil distributing valve body and bearing on the described oil distributing valve bar, be provided with the adjustment packing ring between described oil distributing valve body and the oil distributing valve bar; In the middle of described cylinder body and the oil distributing valve bar solid link rod piston is installed, also is provided with pressure retaining valve in the described cylinder body.
Preferably, also be provided with one-way valve in the described cylinder body.
Preferably, on the described oil distributing valve bar outside framework oil seal is housed also.
Preferably, described bearing is fixed on the cylinder body by back-up ring.
Preferably, described cylinder body and oil distributing valve bar connect together by screw.
Preferably, also be provided with the axis of guide on the described cylinder body.
Preferably, also be provided with seal ring between described link rod piston and the cylinder body.
Compared with prior art, the utility model is installed between the oil distributing valve body of angling cylinder and oil distributing valve bar and is adjusted packing ring, can adjust the gap between oil distributing valve body and the oil distributing valve bar, above-mentioned gap between the two can be controlled artificially, oil pressure loss in the angling cylinder body is controlled in proper level, guarantees that oil pressure is not enough in the cylinder body, realizes the high rotating speed of link rod piston, larger push-pull force output and or dynamics stable, machining workpiece is clamped the more reliable of effect.Simultaneously, also be provided with pressure retaining valve in cylinder body, even outage or pressure source make angling cylinder keep working state in the situation that suddenly interruption in the pressure process also plays pressure maintaining effect temporarily, Security is good.

Embodiment
Below in conjunction with accompanying drawing and embodiment the technical solution of the utility model is described.
The utility model is the single piston pressurize of a kind of middle reality angling cylinder, it comprises cylinder body 10, be installed on the oil distributing valve bar 20 on the cylinder body 10, and be installed on oil distributing valve body 21 and bearing 30 on the described oil distributing valve bar 20, be provided with between described oil distributing valve body 21 and the oil distributing valve bar 20 and adjust packing ring 22; In the middle of described cylinder body 10 and the oil distributing valve bar 20 solid link rod piston 40 is installed, also is provided with pressure retaining valve 50 in the described cylinder body 10.Compared with prior art, the utility model is installed between the oil distributing valve body 21 of angling cylinder and oil distributing valve bar 20 and is adjusted packing ring 22, can adjust the gap between oil distributing valve body 21 and the oil distributing valve bar 20, above-mentioned gap between the two can be controlled artificially, oil pressure loss in the angling cylinder cylinder body 10 is controlled in proper level, guarantee that cylinder body 10 interior oil pressure are not enough, realize the high rotating speed of link rod piston 40, larger push-pull force output and or dynamics stable, machining workpiece is clamped the more reliable of effect.Simultaneously, also be provided with pressure retaining valve 50 in cylinder body 10, even outage or pressure source make angling cylinder keep working state in the situation that suddenly interruption in the pressure process also plays pressure maintaining effect temporarily, Security is good.
In addition, in order to guarantee cylinder body 10 reliable in structure, promote cylinder body 10 sealabilities, and it is stable to increase angling cylinder, also is provided with one-way valve 60 in the described cylinder body 10, on the described oil distributing valve bar 20 outside framework oil seal 70 is housed also, described bearing 30 is fixed on the cylinder body 10 by back-up ring 71, described cylinder body 10 and oil distributing valve bar 20 connect together by screw, also are provided with the axis of guide 80 on the described cylinder body 10, also are provided with seal ring 90 between described link rod piston 40 and the cylinder body 10.
The single piston pressurize of middle reality of the present utility model angling cylinder, it is high that it has an oil cylinder rotating speed, and High power output and stable has advantages of also that simultaneously Safety performance is high.
