Abstract
The invention discloses a rodless cylinder. The rodless cylinder comprises a sleeve, a piston and two barrel covers. A plurality of balls capable of rolling are inlaid in the inner wall of the sleeve. The piston is installed in the sleeve, buffer grooves are formed in the two ends of the piston, and a magnetic stripe is installed in the piston. Air supply holes are formed in the barrel covers, adjustable buffer valves are installed on the barrel covers, and the surfaces of the barrel covers are further provided with buffer shafts. The buffer shafts are connected with the adjustable buffer valves through air passages. Variable electrodes are installed on the two barrel covers. Sensors are installed on side faces of the buffer shafts and are connected with the variable electrodes. Through the method, the rodless cylinder is simple in structure, small in occupied space and good in sealing performance, and air inside the air cylinder is not prone to outward leakage.
Description
Technical field
The present invention relates to field of electromechanical technology, particularly relate to a kind of Rodless cylinder.
Background technique
Cylinder is a kind of more common energy conversion device, compressed-air actuated pressure energy is converted to mechanical energy by it, realize straight reciprocating motion, swing, rotation or percussion action, due to the difference of application, cylinder of a great variety, different, sum up and get up can be divided into two large classes, namely have bar cylinder and Rodless cylinder.Existing have bar cylinder to be connect packed-piston in one end of a motion bar, piston movement is driven by motion bar, be used as a kind of machine power, but this have the structural volume of bar cylinder comparatively huge, space required when therefore installing is also larger, and have bar cylinder due to motion bar may unbalance stress, thus cause controlling location and be affected, validity is poor; Existing Rodless cylinder adopts mechanical type usually, such as mechanical contact Rodless cylinder axially offers a chute at cylinder earthen pipe, piston and slide block move on chute top, compared to there being bar cylinder, this mechanical contact Rodless cylinder installing space is less, and control accuracy is higher, but owing to arranging chute, cause poor sealing performance, air easily produces external leakage, and common Rodless cylinder complex structure, take up room larger.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Rodless cylinder.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of Rodless cylinder, comprising:
One sleeve, described sleeve lining inlays some balls that can roll;
One piston, described piston is arranged in described sleeve, and described piston two ends offer dashpot, are provided with magnetic stripe in described piston;
Two covers, described cover offers air vent, described cover is provided with adjustable trimmer valve, the surface of described cover is also provided with buffer shaft, described buffer shaft is connected by air flue with described adjustable trimmer valve, cover described in two is provided with movable electrode, and described buffer shaft side is provided with inductor, and described inductor is connected with described movable electrode.
In a preferred embodiment of the present invention, described piston matches with described sleeve.
In a preferred embodiment of the present invention, described in two on cover described in two, the electrode of movable electrode is contrary.
In a preferred embodiment of the present invention, described dashpot matches with described buffer shaft.
The invention has the beneficial effects as follows: a kind of Rodless cylinder of the present invention, this Rodless cylinder structure is simple, and shared space is little, and has good sealability, and the air in cylinder is not easy to produce to external leakage.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of Rodless cylinder of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, sleeve; 2, ball; 3, piston; 4, dashpot; 5, magnetic stripe; 6, movable electrode; 7, cover; 8, air vent; 9, adjustable trimmer valve; 10, buffer shaft; 11, inductor.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to Fig. 1, the embodiment of the present invention comprises: a kind of Rodless cylinder, comprising:
One sleeve 1, described sleeve 1 inwall inlays some balls 2 that can roll, and described ball 2 makes to reduce with the area of contact of described piston 3, reduces friction.
One piston 3, described piston 3 is arranged in described sleeve 1, and described piston 3 matches with described sleeve 1.Make described piston 3 movement more smooth and easy in described sleeve 1.
Described piston 3 two ends offer dashpot 4, are provided with magnetic stripe 5 in described piston 3, and described magnetic stripe 5, for coordinating with the described movable electrode 6 at two ends, provides kinetic energy to described piston 3, and described piston 3 can be moved around in described sleeve 1.
Two covers 7, described cover 7 offers air vent 8, described cover 7 is provided with adjustable trimmer valve 9, described adjustable trimmer valve 9 discharges the gas in connected seal chamber, the air pressure reduced wherein reduces the resistance of described piston 3 motion, controlled the air pressure in seal chamber simultaneously by trimmer valve 9 adjustable described in conservative control, reduce the travelling speed of the described piston 3 of high-speed mobile, prevent it from clashing into described cover 7.
The surface of described cover 7 is also provided with buffer shaft 10, and described dashpot 4 matches with described buffer shaft 10.
When described piston 3 moves right, described adjustable trimmer valve 9 on right described cover 7 is vented, after described piston 3 moves right and puts in place, described air vent 8 on left described cover 7 is closed, and the described air vent 8 on right described cover 7 opens air feed, and described piston 3 is moved to the left, at this moment, described adjustable trimmer valve 9 on left described cover 7 is vented, and described piston 3 completes and once moves, the motion that described piston 3 goes round and begins again.
Described buffer shaft 10 is connected by air flue with described adjustable trimmer valve 9, cover 7 described in two is provided with movable electrode 6, described buffer shaft 10 side is provided with inductor 11, described in two, the electrode of movable electrode 6 is contrary, contrary electrode makes described piston 3 provide pulling force in one end when moving, one end provides thrust, motion is got up more smooth.
Described inductor 11 is connected with described movable electrode 6, and when described dashpot 4 front end is through described inductor 11, described in two, movable electrode 6 slowly changes, and reduces the impact of described piston 3 to described cover 7.
Compared with prior art, a kind of Rodless cylinder of the present invention, this Rodless cylinder structure is simple, and shared space is little, and has good sealability, and the air in cylinder is not easy to produce to external leakage.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
