Abstract
The utility model relates to hydraulic equipment, in particular to a telescopic piston cylinder, and belongs to the technical field of mechanical manufacture. The telescopic piston cylinder comprises a cylinder body. A combined type piston rod I and a combined type piston rod II are arranged in the cylinder body. The combined type piston rod I is arranged in the combined type piston rod II, and a guide sleeve II is compacted through a gland nut to form a first level telescopic cylinder. The first level telescopic cylinder is installed in the cylinder body, and a guide sleeve I and a cylinder mouth flange are fixed on the cylinder body through bolts. System pressure oil enters the oil cylinder through an oil mouth B and ejects the combined type piston rod I out to a certain position and then ejects the combined type piston rod II out. A rod containing chamber (C chamber) discharges the oil into a rod containing chamber (D chamber) through an oil path on the combined type piston rod II, and then the oil in the D chamber is discharged back to the system through an oil mouth A. The telescopic piston cylinder is applied to driving moving parts of hydraulic equipment with a big route and a small table board, and achieves back and forth movement of the moving parts.
Description
Technical field
The utility model relates to a kind of hydraulic equipment, is specifically related to a kind of telescopic piston cylinder, belongs to machinery manufacturing technology field.
Background technique
At present; Hydraulic equipment with hydraulic oil cylinder driving is a lot; Often use telescopic piston type cylinder drive motion components for big stroke hydraulic equipment, separately by the backhaul hydraulic oil cylinder driving, the moving element of so big stroke hydraulic equipment needs very big installing space during backhaul; Can increase the manufacture cost of the little table top hydraulic equipment of big stroke like this, cause unnecessary waste.
Summary of the invention
The purpose of the utility model is for overcoming the deficiency of above-mentioned existing technology, a kind of telescopic piston cylinder is provided, and this piston cylinder includes cylinder body, and combined live stopper rod I, combined live stopper rod II are arranged in the cylinder body; Described combined live stopper rod I is installed in the combined live stopper rod II, compresses the guide pin bushing II through gland nut, forms first order telescopic cylinder; First order telescopic cylinder is packed in the cylinder body, guide pin bushing I, cylinder mouth flange are fixed on the cylinder body through bolt.System pressure oil gets into oil cylinder through the B hydraulic fluid port; Combined live stopper rod I is ejected; Eject and combined live stopper rod II is ejected after putting in place again, rod chamber (C chamber) oil extraction is to enter rod chamber (D chamber) through the oil circuit on the combined live stopper rod II, and the oil in D chamber is expelled back into system through the A hydraulic fluid port.This piston cylinder is used to drive the moving element of the hydraulic equipment of the little table top of big stroke, has satisfied the moving element back and forth movement.
The utility model is realized through following technological scheme: a kind of telescopic piston cylinder is characterized in that: this piston cylinder includes cylinder body, and combined live stopper rod I, combined live stopper rod II are arranged in the cylinder body; Described combined live stopper rod I is installed in the combined live stopper rod II, compresses the guide pin bushing II through gland nut, forms first order telescopic cylinder; First order telescopic cylinder is packed in the cylinder body, guide pin bushing I, cylinder mouth flange are fixed on the cylinder body through bolt.
There is the B hydraulic fluid port described cylinder body front portion, and there is the A hydraulic fluid port at the cylinder body rear portion.
Rod chamber (C chamber) is arranged between described combined live stopper rod I and the combined live stopper rod II; Rod chamber (D chamber) is arranged between described cylinder body and the combined live stopper rod II.
The utility model has the advantages that: this telescopic piston cylinder compact structure, low cost of manufacture, installation and maintenance are convenient, are used to drive the moving element of the hydraulic equipment of the little table top of big stroke, satisfied the moving element back and forth movement, and are reliable.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below:
Accompanying drawing is the utility model structural representation;
Among the figure: 1, cylinder body, 2, combined live stopper rod I, 3, combined live stopper rod II, 4, the guide pin bushing I, 5, the guide pin bushing II, 6, cylinder mouth flange, 7, gland nut, A hydraulic fluid port, B hydraulic fluid port.
Embodiment
As shown in the figure: a kind of telescopic piston cylinder, this piston cylinder includes cylinder body 1, and combined live stopper rod I 2, combined live stopper rod II 3 are arranged in the cylinder body; Described combined live stopper rod I is installed in the combined live stopper rod II, compresses guide pin bushing II 5 through gland nut 7, forms first order telescopic cylinder; First order telescopic cylinder is packed in the cylinder body, guide pin bushing I 4, cylinder mouth flange 6 are fixed on the cylinder body through bolt.
Described cylinder body front portion has
BHydraulic fluid port, there is the A hydraulic fluid port at the cylinder body rear portion.
Rod chamber (C chamber) is arranged between described combined live stopper rod I 2 and the combined live stopper rod II 3; Rod chamber (D chamber) is arranged between described cylinder body and the combined live stopper rod II 3.
Working procedure: telescopic piston cylinder is mainly accomplished to eject and is return; When piston cylinder ejects; System pressure oil gets into oil cylinder through the B hydraulic fluid port; Combined live stopper rod I is ejected, eject and combined live stopper rod II is ejected after putting in place again, rod chamber (C chamber) oil extraction is to flow back to system through the oil that the oil circuit on the combined live stopper rod II enters rod chamber (D) through the A hydraulic fluid port.Otherwise when the pressure oil of hydraulic system gets into the D chamber through the A hydraulic fluid port, combined piston bar II is return, return put in place after, pressure oil gets into the C chamber through the oil circuit on the combined live stopper rod II, and combined live stopper rod I is return, oil extraction all flows back to system through the B mouth.Telescopic piston cylinder is accomplished to eject and is return action.
