Abstract
The utility model discloses a soft location hydro -cylinder, including cylinder, cylinder bottom, piston rod and piston, it has first hydraulic fluid port and second hydraulic fluid port to open on the cylinder, and the cylinder bottom is connected in cylinder one end, and the uide bushing is installed to the cylinder other end, and the piston rod passes the uide bushing and installs in the cylinder, and piston rod one end has the piston, and slotted nut and lock nut are installed to the other end, and slotted nut and lock nut and piston rod threaded connection, slotted nut be to outside the uide bushing on the terminal surface, and lock nut is to on the slotted nut terminal surface, slotted nut has the threaded holes and unthreaded hole, screw thread hole center line and the coincidence of light hole center line, and the screw hole diameter is less than the unthreaded hole diameter. Realize the fine setting of different locating distances and different strokes through the relative position between slotted nut and the lock nut on the regulating piston pole, satisfy multiple operating mode needs.
Description
Technical field
The utility model belongs to fork truck oil cylinder, specifically a kind of soft positional cylinder.
Background technique
At present, fork truck oil cylinder is of a great variety, there are accessory oil cylinder, dump ram, roll adjustment oil cylinder, sidesway oil cylinder etc., these oil cylinders can meet various working needs, but have a common defects, are exactly that after installing, effect is single, stroke is non-adjustable, if need different strokes, or installing space changes, just need to change oil cylinder, consuming time, effort.
Model utility content
In order to solve the defect existed in prior art, the utility model provides a kind of soft positional cylinder, this oil cylinder realizes the fine setting of different mounting distance and different stroke by the relative position between slotted nut on regulating piston bar and locking nut, do not need frequently to change oil cylinder, just can meet various working needs.
For solving the problems of the technologies described above, the utility model provides a kind of soft positional cylinder, comprise cylinder barrel, cylinder bottom, piston rod and piston, cylinder barrel has the first hydraulic fluid port and the second hydraulic fluid port, cylinder bottom is connected to cylinder barrel one end, the cylinder barrel the other end is provided with guide sleeve, piston rod is arranged in cylinder barrel through guide sleeve, there is piston piston rod one end, the other end is provided with slotted nut and locking nut, slotted nut is connected with piston rod thread with locking nut, slotted nut is against in guide sleeve end face outside, locking nut is against on slotted nut end face, described slotted nut has tapped hole and unthreaded hole, tapped hole center line overlaps with unthreaded hole center line, tapped hole diameter is less than unthreaded hole diameter.
For the purpose of describing the problem, below to soft positional cylinder described in the utility model all referred to as this oil cylinder.
When needs increase stroke, required separation distance of being back-outed to the direction away from cylinder bottom by slotted nut, then uses locking nut positioning and locking; When needs reduce stroke, required separation distance of being back-outed to the direction near cylinder bottom by slotted nut, then uses locking nut positioning and locking.This oil cylinder realizes the fine setting of different mounting distance and different stroke by the relative position between slotted nut on regulating piston bar and locking nut, meets various working needs.This oil cylinder can be used in multiple machinery, such as tilting oil cylinder of fork, and about during use, cylinder has the synchronism requirement of height, utilizes this oil cylinder accurately can adjust in the scope of pitch 1 ~ 2mm, reaches usage requirement.The slotted nut of this oil cylinder is connected with piston rod thread with locking nut, has monolithic construction, reduces assembling difficulty, and simple to operate, increases work efficiency.
Piston rod is equipped with earrings away from one end of cylinder bottom, and earrings is connected with piston rod thread.By regulating the relative position of earrings and piston rod, while meeting stroke adjustment, can also finely tune mounting distance.
