Abstract
The invention belongs to the technical field of fluid actuation device, and discloses a pneumatic mechanism for rotary output. The pneumatic mechanism comprises a cylinder body of a cylinder, wherein a piston is arranged in the cylinder body; an air inlet/outlet is formed in the sidewall of each of the two sides of the cylinder body; a threaded hole is eccentrically formed in the end face of the output end of the piston, and is matched with a screw rod axially arranged in the cylinder body; the output end of the screw rod is fixedly connected with a rotary output shaft outside the cylinder body. The pneumatic mechanism is smaller in size and lower in cost.
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.Actuator is needed to rotate in a lot of manufacturing procedure in existing equipment, at present in order to achieve the above object, in actuator, normally increase leading screw, screw mandrel or other the device that to-and-fro motion can be become rotary motion, but the volume of integral device seems very large like this, and the costs such as transport, installation, occupation of land are also higher.
Summary of the invention
The invention is intended to the pneumatic mechanism providing a kind of small volume, lower-cost rotation exports.
Technological scheme in this programme is: rotate the pneumatic mechanism exported, comprise the cylinder body of cylinder, piston is provided with in cylinder body, the two ends sidewall of cylinder body has an air air inlet/outlet separately, on the output terminal end face of described piston, eccentric setting has screw, the screw mandrel axially arranged in this screw and cylinder body cooperatively interacts, the output terminal of this screw mandrel and the rotating output shaft of cylinder body outside affixed.
The beneficial effect of this programme is: the screw that eccentric setting coordinates with screw mandrel on piston, when air enters from two air ports are staggered, piston can horizontally slip in cylinder body, because piston and rotating output shaft are eccentric settings, therefore piston can not rotate dynamic, but the movement of piston can make the screw mandrel coordinated with it rotate, thus the clockwise and anticlockwise of driven rotary output shaft, and, because leading screw is arranged in cylinder block, reduce the volume of whole equipment, reduce the costs such as transport, installation.
Further, cylinder body is provided with thrust bearing in the contacting point with leading screw output terminal, bears the end thrust of leading screw, reduces the friction of leading screw, ensures the stationarity of screw turns.
Further, bottom the screw of piston output terminal end face, be also provided with the reaming that diameter is less than screw, make to add man-hour during screw convenient.
Further, the perisporium of piston has seal groove, seal groove internal fixtion has the rubber seal of O type, improves the tightness of piston both sides cavity.
Accompanying drawing explanation
Fig. 1 is the schematic front view that the present invention rotates the pneumatic mechanism embodiment of output.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: 1-cylinder body, 2-piston, 3-O RunddichtringO, 4-rotating output shaft, 5-screw mandrel, 6-thrust bearing, 7-first air ports, 8-second air ports.
Embodiment is substantially as shown in drawings: rotate the pneumatic mechanism exported, comprise the cylinder body 1 of tubular, this cylinder body 1 is threaded integral by cylinder body, protecgulum and bonnet, wherein cylinder body is inner with piston cavity, piston 2 is combined with in piston cavity, the perisporium of this piston 2 has seal groove, O RunddichtringO 3 is installed in seal groove.
Protecgulum has the first air ports 7 communicated with piston cavity, cylinder back cover center also has the second air ports 8 communicated with piston cavity.The protecgulum of cylinder body 1 is run through by rotating output shaft 4 bias, and this rotating output shaft 4 stretches in piston cavity.
Piston 2 is output terminal end face towards the end face of protecgulum, and on this output terminal end face, bias has screw, and the bottom of screw is less than the screw of screw with diameter.This screw coordinates with a screw mandrel 5, screw mandrel 5 output terminal and rotating output shaft 4 integrally casting shaping, cylinder body 1 is provided with thrust bearing 6 in the contacting point with leading screw output terminal.
During use, the first air ports 7 and the second air ports 8 are interlocked air inlet, promote piston 2 and move left and right in piston cavity, and because piston 2 is eccentric relative to rotating output shaft 4, piston 2 can not rotate.During the moving axially of piston 2, screw mandrel 5 and screw occur mutually to rotate, and promotion screw mandrel 5 rotates, the clockwise and anticlockwise thus rotating output shaft 4 also hockets.
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.
