Abstract

A multi-stage located cylinder is composed of left and right end covers, cylinder body, piston with at least one retainer ring at its left and right ends, piston rod, sealing ring, left and right spring, fixing screw bolts and nuts. The working chamber divided into more working cavities is formed by left and right retainer rings, piston and left and right end covers. The piston rod is located by the position of retainer rings.

Description

Multistage positional cylinder
(1) technical field
The present invention relates to a kind of location gas, oil cylinder, especially multistage pinpoint gas, oil cylinder.
(2) background technique
At present at hydraulic pressure, pneumatic industry, and on the automatic industrial manufacturing line, have to require liquid, cylinder can accurately stretch out 2 grades, 3 grades, 4 grades under many situations ... the n level.For example in the grain packaging industry, require liquid, cylinder to stretch out 3 grades, 4 grades; On automatic line, require cylinder to stretch out 4 grades, 5 grades even more sometimes.All there is not multi-level oil to determine a position telescopic cylinder from the two tame German FESTO of enterprise that produce the pneumatic product maximum in the world, Xiao Jin well etc.; It is three position cylinder that Japan SMC has a, and it has only two-stage output in fact, when middle position is exported, because by the gas location, gas has compressibility, so the position of central authorities is fixed position accurately, flutter phenomenon appears probably, in addition in backhaul,, in the chamber, produce a dead volume in the process of stretching out because gas has part can leak in the cavity volume between two chambeies, therefore can't arrive the exact position in the gas backhaul, this is the defective of this kind cylinder maximum.Do not found similar oil cylinder at present.A kind of hot sealing device that has multistage cylinder of CN95225104.3 patent disclosure, comprise gear-box, main shaft, cam, roller, centering guide, down heat seal die and down the heat seal die die holder, go up heat seal die and go up heat seal die die holder, cover plate and pressure cylinder.Pressure cylinder is multistage cylinder, the progression n=2,3,4 of this multistage cylinder ... it by cylinder sleeve, the upper end cap that places the cylinder sleeve upper and lower port and lower end cap, place in the cylinder sleeve and with cylinder sleeve n etc. be separated into n little cylinder sleeve (n-1) individual spacer ring, pass spacer ring and lower end cap mandrel, be arranged on the mandrel and be in n piston formation of n little cylinder sleeve respectively, upper end cap is provided with the forward inlet hole, lower end cap is provided with reverse inlet hole, then is respectively arranged with forward inlet hole and reverse inlet hole in the spacer ring both sides.
(3) summary of the invention
The present invention aims to provide a kind of energy and realizes multistage pinpoint gas, oil cylinder.
The present invention is provided with left and right sides end cap, cylinder barrel, piston, piston rod, seal ring, left and right sides spring, retaining thread bar and nut, and end respectively is provided with at least 1 back-up ring (dividing another name left and right sides back-up ring) about piston.Form the corresponding work chamber by left and right back-up ring and piston, left and right sides end cap.
Because the present invention only is provided with 1 piston and 1 piston rod, and 1~n back-up ring arranged at the left end of piston, and at the right-hand member of piston 1~n back-up ring arranged equally, come the position of positioning piston bar according to the position of back-up ring, no matter stretch out still and shrink, can accurately determine on a certain desired location.Secondly active chamber is made up of a plurality of active chambers, thereby can realize multistage output, multistage location.Select different active chamber air inlets (oil) and exhaust (oil), then release different positions, can satisfy the requirement of industrial multi-stage expansion.
(4) description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
(5) embodiment
Following examples will the present invention is further illustrated in conjunction with the accompanying drawings.
Referring to Fig. 1, the present invention is made up of following critical piece: left and right sides end cap 1,10, cylinder barrel 2, piston 3, piston rod 4, left back-up ring 21, right back-up ring 5,16, seal ring 6,7,8,9,15,17,20 etc., left and right sides spring 14,22, threaded stem 11, nut 12,19, pad 13,18 etc.
When the air inlet of C chamber (oil), during all the other chamber exhausts (oil), gas (oil) cylinder is position 1; Work as A, C chamber air inlet (oil), during all the other exhausts (oil), gas (oil) cylinder reaches position 2; Work as B, D chamber air inlet (oil), during all the other exhausts (oil), gas (oil) cylinder reaches position 3; And the like, if select different chamber air inlet (oil) and exhaust (oil), then can release different positions, obvious, it can satisfy in the industrial production under many situations the demand to multi-stage expansion.

Claims (1)

1, multistage positional cylinder, it is characterized in that being provided with left and right sides end cap, cylinder barrel, piston, piston rod, seal ring, left and right sides spring, retaining thread bar and nut, end respectively is provided with at least 1 back-up ring about piston, forms the corresponding work chamber by left and right back-up ring and piston, left and right sides end cap.
