Description
Technical field
The invention belongs to fluid actuator technical field.
Background technique
The pneumatic structures such as existing cylinder be widely used in engineering equipment and and, the execution architecture that conventional cylinder comprises cylinder body, piston rod and is connected with piston rod.Cylinder is generally divided into single-acting, double-acting cylinder; its way of output also can be divided into rotation output, straight line output etc.; in existing factory process process; usually can use multiple different types of cylinder, such as, use rotary cylinder and straight line to export cylinder simultaneously and carried out pressing down and the action such as clamping workpiece.
The shortcoming of such scheme is: need to install multiple cylinder in machinery to realize different cylinder actions, its volume can seem comparatively huge, and need these cylinders to be connected in master controller, control program is comparatively loaded down with trivial details, in addition, the transport of these cylinders, purchase and installation cost are higher, are not suitable for some small processing factories.
Summary of the invention
The invention is intended to provide one to export and lower-cost multiaction pneumatic mechanism by various ways.
Technological scheme in this programme is: multiaction pneumatic mechanism, comprise cylinder body, the two ends of cavity are protecgulum and bonnet, with the piston cavity being provided with piston in cylinder body, the piston rod that piston connects runs through protecgulum and the bonnet of shaven head, described piston cavity is oval piston cavity, and piston includes and to coordinate with piston cavity and to be rotary-piston and the translating piston of ellipse; The position that piston rod coordinates with rotary-piston is screw mandrel, and the both sides of this screw mandrel are provided with the limiting stopper preventing rotary-piston from exiting screw mandrel; Thrust-bearing is provided with between translating piston and piston rod; Have the first air ports between rotary-piston and cylinder body protecgulum, the cylinder body between rotary-piston and translating piston has the second air ports, between translating piston and cylinder body bonnet, have the 3rd air ports.
The beneficial effect of this programme is: the present invention is by arranging three air inlet/outlets, rotary-piston and translating piston, and piston cavity is done ovalisation, due to coordinating of rotary-piston and screw mandrel, when making rotary-piston translation, leading screw rotates, now also rotate with the piston rod of leading screw consubstantiality, piston rod is made to rotate output, in addition, adjust the combination gone out into air air inlet/outlet, translating piston is made to receive compressed-air actuated thrust, translating piston is moved in piston cavity, thus drives piston rod to be moved, piston rod straight line is exported.The present invention can according to the combination of different air air inlet/outlets, the various combinations that can obtain the rotating forward of piston rod, reverse, move to left, move to right, cylinder without the need to arranging multiple types can realize the multifunctional output of multimode, greatly reduce purchase, install and cost of transportation, without the need to working out loaded down with trivial details director demon, be applicable to small processing factory.
Further, the side face that described piston rod and the protecgulum of cylinder body contact with bonnet is provided with O RunddichtringO, improves the tightness of piston cavity.
Further, described limiting stopper is welding annular ring on the piston rod, reduces difficulty of processing, and has good limit effect.
Further, the side of described rotary-piston, translating piston is provided with rubber seal, prevents pressurized air from revealing and friction can be reduced.
Accompanying drawing explanation
Fig. 1 is the schematic front view of multiaction pneumatic mechanism embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: 1-cylinder body; 2-protecgulum; 3-bonnet; 4-piston rod; 5-O RunddichtringO; 6-rotary-piston; 7-translating piston; 8-annular ring; 9-screw mandrel; 10-thrust-bearing.
Multiaction pneumatic mechanism, comprises cylinder body 1, with the piston cavity of ellipse in cylinder body 1.As shown in Figure 1, the left end of cylinder body 1 is protecgulum 2, cylinder body 1 right-hand member is bonnet 3, with the piston rod 4 axially running through protecgulum 2, bonnet 3 in the piston cavity of cylinder body 1, is sealed between piston rod 4 and protecgulum 2, bonnet 3 by O RunddichtringO 5.The inherent piston rod 4 of piston cavity is provided with rotary-piston 6 and translating piston 7 from left to right successively, the shape of this rotary-piston 6 and translating piston 7 is mates ellipse with piston cavity, they do not rotate in piston cavity, and the side of rotary-piston 6, translating piston 7 is fixed with rubber seal.Cylinder body 1 between rotary-piston 6 and protecgulum 2 has air ports A, the cylinder body 1 between rotary-piston 6 and translating piston 7 has air ports B, the cylinder body 1 between translating piston 7 and bonnet 3 has air ports C.The position that piston rod 4 coordinates with rotary-piston 6 is screw mandrel 9, the left and right sides of screw mandrel 9 is fixed with limiting stopper respectively, this limiting stopper is the annular ring 8 be welded on piston rod 4, and the movement of rotary-piston 6 on screw mandrel 9 can make screw mandrel 9 rotate, thus piston rod 4 rotates.The thrust-bearing 10 that a pair direction is contrary is fixed with between piston rod 4 with translating piston 7.
The working procedure of this enforcement is as follows:
1, piston rod 4 rotates forward: open air ports A and air ports B, occluded air imports and exports C, air ports A passes into pressurized gas, air ports B output squeezing gas, thus promote rotary-piston 6 and move to right in piston cavity, thus screw mandrel 9 is rotated and drives piston rod 4 to rotate forward, owing to being thrust-bearing 10 between piston rod 4 and translating piston 7, when piston rod 4 rotates, translating piston 7 is unaffected, and piston rod 4 exports and rotates forward.
2, piston rod 4 reverses: open air ports A and air ports B, occluded air imports and exports C, air ports B passes into pressurized gas, air ports A output squeezing gas, promote rotary-piston 6 to move to left in piston cavity, thus screw mandrel 9 is rotated and drives piston rod 4 to reverse, owing to being thrust-bearing 10 between piston rod 4 and translating piston 7, when piston rod 4 rotates, translating piston 7 is unaffected, and piston rod 4 exports and rotates backward.
3, piston rod 4 moves to right:
Scheme one: open air ports B and air ports C, occluded air imports and exports A, air ports B passes into pressurized gas, air ports C output squeezing gas, promote translating piston 7 to move to right in piston cavity, owing to being thrust-bearing 10 between piston rod 4 and translating piston 7, moving to right of translating piston 7 can drive piston rod 4 to move to right, and now rotary-piston 6 and screw mandrel 9 are equivalent to an entirety and move to right along with moving to right of piston rod 4.So, piston rod 4 straight line motion to the right.
Scheme one: open air ports A and air ports C, occluded air imports and exports B, air ports A passes into pressurized gas, air ports C output squeezing gas, promotion rotary-piston 6 and translating piston 7 move to right in piston cavity, and because ellipse during rotary-piston 6 can not rotate with piston cavity, therefore do not rotate between rotary-piston 6 and screw mandrel 9 formation entirety, so, piston rod 4 straight line motion to the right.
4, piston rod 4 moves to left: the setting moved to right see piston rod 4, only need exchange pressurized air turnover direction, can realize piston rod 4 and move to left.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in specification etc. record the content that may be used for explaining claim.
