Description
Technical field
The utility model relates to a kind of lathe headstock speed change oil cylinder, especially lathe three speed change oil cylinders of single cylinder single-piston rod.
Background technology
In machine tool structure field, the speed change oil cylinder of lathe headstock is necessary component.In recent years, the combined machine development with C axle indexing case is very fast, and the speed change request of its main spindle box has fast, slow two grades, and requires reliable meta shelves.Existing main spindle box generally adopts compound sleeve cylinder at speed change oil cylinder, thus exists and takes up room greatly, controls complicated and that reliability is low problem.
Summary of the invention
Taking up room greatly to solve existing speed change oil cylinder, controlling complicated and that reliability is low problem.The utility model provides lathe three speed change oil cylinders of a kind of single cylinder single-piston rod.Lathe three speed change oil cylinders of this single cylinder single-piston rod have and take up room little, control the feature that easy and reliability is high.
The technical solution of the utility model is: lathe three speed change oil cylinders of this single cylinder single-piston rod comprise main spindle box body, oil cylinder, piston rod, switch collision block, travel switch, shift fork.Oil cylinder is laterally fixedly connected on main spindle box body by positioning nut, oil cylinder right-hand member has right oil-in, oil cylinder left end has left oil inleting port, oil cylinder there is steam vent, piston rod right-hand member has piston bush, shift fork connects on the piston rod, and 3 switch collision blocks are connected to piston rod right-hand member, and three contact travel Switch Controller inductive switch collision blocks are fixedly connected on main spindle box body.
The utility model has following beneficial effect: lathe three speed change oil cylinders of this single cylinder single-piston rod are laterally fixedly connected on main spindle box body owing to adopting oil cylinder by positioning nut, oil cylinder right-hand member has right oil-in, oil cylinder left end has left oil inleting port, oil cylinder there is steam vent, piston rod right-hand member has piston bush, shift fork connects on the piston rod, and 3 switch collision blocks are connected to piston rod right-hand member, and three contact travel Switch Controller inductive switch collision blocks are fixedly connected on the structure on main spindle box body.Utilize single cylinder single-piston rod to reach the object of three speed changes, thus reduce to take up room, easy control and raising reliability.Lathe three speed change oil cylinders of this single cylinder single-piston rod have and take up room little thus, control the feature that easy and reliability is high.

Accompanying drawing 1 is the utility model structural representation.
1-main spindle box body in figure, 2-oil cylinder, 3-piston rod, 4-switch collision block, 5-travel switch, 6-shift fork.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in accompanying drawing, lathe three speed change oil cylinders of this single cylinder single-piston rod comprise main spindle box body 1, oil cylinder 2, piston rod 3, switch collision block 4, travel switch 5, shift fork 6.Oil cylinder 2 is laterally fixedly connected on main spindle box body 1 by positioning nut, oil cylinder 2 right-hand member has right oil-in, oil cylinder 2 left end has left oil inleting port, oil cylinder 2 there is steam vent, piston rod 3 right-hand member has piston bush, shift fork 6 is connected on piston rod 3, and 3 switch collision blocks 4 are connected to piston rod 3 right-hand member, and three 5 pairs, contact travel switch inductive switch collision blocks 4 are fixedly connected on main spindle box body 1.
The course of work:
1, right-hand member position, shift fork 6 place: left oil inleting port enters pressure oil, right oil-in oil return, pressure oil promotion piston rod 3, piston bush are to the right-hand member of oil cylinder, piston rod 3 drives shift fork 6 to the right-hand member speed change position on it, and piston rod 3 drives the right-hand member contact of the left end switch collision block 4 pressing travel switch 5 on it to send out right-hand member speed change position and to put in place signal.
2, left end position, shift fork 6 place: right oil-in enters pressure oil, left oil inleting port oil return, pressure oil promotes the right-hand member of piston rod 3 to oil cylinder, promote the middle part limit position of piston bush to oil cylinder simultaneously, piston rod 3 drives shift fork 6 to the left end speed change position on it, and piston rod 3 drives the left end contact of the right-hand member switch collision block 4 pressing travel switch 5 on it to send out left end speed change position and to put in place signal.
3, shift fork 6 place meta: left oil inleting port and right oil-in enter pressure oil simultaneously, because oil cylinder 2 is different from left, center, right three cavity area that piston rod 3, piston bush are formed, under the effect of pressure differential, piston bush is to the limit position, middle part of oil cylinder, piston rod 3 is close to the meta of left side to oil cylinder of piston bush, piston rod 3 drives shift fork 6 to the meta neutral position on it, and piston rod 3 drives the mid-position contact of the intermediate switch collision block 4 pressing travel switch 5 on it to send out meta neutral position and to put in place signal.
The left, center, right stroke of oil cylinder 2 is ensured by accessory size, and the rigging position of shift fork 6 is adjusted by two positioning nuts of main spindle box body 1 both sides and locked.Steam vent ensures turnover gas during oil cylinder middle cavity Volume Changes.Lathe three speed change oil cylinders of this single cylinder single-piston rod compare with speed change oil cylinder, and one takes up room little, and the space being beneficial to main spindle box is arranged; Its two control is easy, only 2 oil-ins, and the compound sleeve cylinder of prior art needs 4; Its three due to the few reliability of part high; Its four manufacture craft is simple, and its five manufacturing cost is lower.
