Abstract
The utility model relates to a kind of cylinder, and particularly one holds out against cylinder, comprises the cylinder body being provided with A pore and B pore, front cover, piston rod, piston, spring.Described piston rod, through described front cover and described piston consolidation, can move with described piston axial reciprocating in the cavity that described cylinder body and described front cover are formed.Described spring is arranged between described cylinder body and described piston.Described front cover front end is provided with installation screw thread.The spherical chamfering of described cylinder ends.The utility model is that single-acting cylinder and double-acting cylinder function organically combine in fact, and pressure is large, when losing source of the gas, still has certain pressure to ensure safety; During installation, wholely hold out against cylinder turn-knob is in frock as a large-scale screw, therefore structure is simple, easy for installation; Good airproof performance simultaneously, long service life.The pneumatic control fields such as weaving, printing, medical apparatus and frock clamping can be widely used in.
Description
Technical field
The utility model relates to a kind of cylinder, and particularly one holds out against cylinder.
Background technique
Hold out against the aerobraking mechanism that cylinder is widely used in frock clamping or equipment, general stroke is shorter, and piston rod ejecting force is larger.The existing cylinder that holds out against mostly is common double active cylinder, and volume is comparatively large, and front cover or flange need be had to be fixed, and installing small space makes troubles; Especially when losing gaseity, ejecting force disappears immediately, sometimes can cause various accident by the workpiece whereabouts held out against or parts Rapid reset.If utilize and have the single-acting cylinder of Returnning spring as holding out against cylinder, although overcome the ejecting force extinction tests immediately when losing gaseity, but the ejecting force only by producing after spring reset is not enough to top tight workpiece or brake member, moreover one end of single-acting cylinder often communicates with air, and carry out gas exchanges with air, enter in cylinder easily to produce containing dust or corrosive gas and scratch or corrosion phenomenon, affect its working life.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, provides a kind of structure simple, easy for installation, and pressure is large, has again spring reset function, good airproof performance hold out against cylinder.
The utility model realizes by the following technical solutions for solving the problems of the technologies described above:
One holds out against cylinder, comprises cylinder body, front cover, piston rod, piston, spring.Described piston rod, through described front cover and described piston consolidation, can move with described piston axial reciprocating in the cavity that described cylinder body and described front cover are formed.Described spring is arranged between described cylinder body and described piston.
Described cylinder body is provided with A pore and B pore.
When the air inlet of A pore, piston rod indentation, and when not having source of the gas, under the action of the spring, piston rod stretches out, this is the function of single-acting cylinder in fact; When the air inlet of A pore, piston rod indentation, and when the air inlet of B pore, piston rod moves outward, this is again the function of double-acting cylinder.When the air inlet of B pore, piston rod moves outward, and pressure size is determined by intake air pressure.
Described front cover front end is provided with installation screw thread, and described cylinder ends makes spherical chamfering simultaneously, conveniently grips turn-knob.
Be provided with guide copper sleeve between described front cover and described piston rod, piston rod is play the guiding role.
Be provided with dust ring between described front cover and described piston rod, prevent dust or corrosive gas from entering cylinder.
The beneficial effect that the utility model has is: single-acting cylinder and double-acting cylinder function are organically combined, pressure is large, when losing source of the gas, still has certain pressure to ensure safety; During installation, wholely hold out against cylinder turn-knob is in frock as a large-scale screw, therefore structure is simple, easy for installation; Good airproof performance simultaneously, long service life.The pneumatic control fields such as weaving, printing, medical apparatus and frock clamping can be widely used in.
Accompanying drawing explanation
Fig. 1 is the utility model: one holds out against cylinder outline drawing.
Fig. 2 is the utility model: one holds out against cylinder erection drawing.
Description of symbols in figure: 1, piston rod; 2, dust ring; 3, screw thread is installed; 4, guide copper sleeve; 5, front cover; 6, piston; 7, A pore; 8, B pore; 9, spring; 10, cylinder body.
Embodiment
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to shown in Fig. 2, one holds out against cylinder, comprises cylinder body 10, front cover 5, piston rod 1, piston 6, spring 9.Described piston rod 1, through described front cover 5 and described piston 6 consolidation, can move with described piston 6 axial reciprocating in the cavity that described cylinder body 10 and described front cover 5 are formed.Described spring 9 is arranged between described cylinder body 10 and described piston 6.
Described cylinder body 10 is provided with A pore 7 and B pore 8.
When not having source of the gas, under the effect of spring 9, piston rod 1 stretches out maintenance and holds out against state, but pressure is the elastic force of spring 9; When 7 air inlet of A pore, piston rod 1 indentation, does not hold out against.When 7 air inlet of A pore, piston rod 1 indentation, and when not having source of the gas, under the effect of spring 9, piston rod 1 stretches out, this is the function of single-acting cylinder in fact.
When 8 air inlet of B pore, piston rod 1 moves outward, and pressure large young pathbreaker determined by intake air pressure.When 7 air inlet of A pore, piston rod 1 indentation, and when 8 air inlet of B pore, piston rod 1 moves outward, this is again the function of double-acting cylinder.
Described front cover 5 front end is provided with installs screw thread 3, and spherical chamfering is made in described cylinder body 10 end simultaneously, conveniently grips turn-knob.The whole cylinder turn-knob as a large-scale screw that holds out against, in frock, is conveniently installed.
Be provided with guide copper sleeve 4 between described front cover 5 and described piston rod 1, piston rod 1 is play the guiding role.
Be provided with dust ring 2 between described front cover 5 and described piston rod 1, prevent dust or corrosive gas from entering cylinder.
More than show and describe the technical solution of the utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
