Description
Technical field
The present invention relates to a kind of oil cylinder of hydraulic headstock gear.
Background technique
Oil cylinder of hydraulic headstock gear has the following problems in assembly at present: first is that piston rod seal component is filled from tailpiece of the piston rod
Fashionable, the flat position since tailpiece of the piston rod is arranged in is easy to scratch sealing element, and easy oil leakage when use influences using effect, second is that dress
The flat position of timing, seized piston rod end needs very big spanner, it has not been convenient to which being equipped with influences assembly efficiency and assembling quality.
Summary of the invention
The purpose of the present invention: designing a kind of oil cylinder of hydraulic headstock gear when assembling piston rod seal component, sealing element not with work
The flat position at stopper rod end contacts, and prevents the possibility for scratching sealing element, does not have to big spanner energy seized piston bar, greatly increases life
Efficiency is produced, and can guarantee the quality and reliability of assembly again.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of oil cylinder of hydraulic headstock gear includes: cylinder head component 1, piston component 2, cylinder barrel 3, piston rod 4, guide sleeve component 5, piston
Shaft seal 6, rod end small stair 7, small stair keyway 8 and rod end screw thread 9.
Rod end small stair 7 and small stair keyway 8 are set on piston rod 4.
The outer circle of rod end small stair 7 is less than the outer circle of piston rod 4, and multiple small stair keyways 8 are evenly arranged on rod end small stair 7
On.
When oil cylinder assembles, piston rod seal component 6 will not rub small stair keyway 8 and damage, multiple 8 conducts of small stair keyway
Rod end screw thread 9 connect stress point when tightening with auxiliary equipment, conveniently tightens screw thread.
The beneficial effects of the present invention are:
A kind of oil cylinder of hydraulic headstock gear, when assembly, will not scratch piston rod seal component, prevent in right, substantially increasing oil cylinder makes
Reliability reduces a large amount of maintenance cost.
Do not have to very big spanner when assembling piston rod, with common hook spanner can, and assembling quality is reliable.
The present invention is described in detail with reference to the accompanying drawings of the specification.
Detailed description of the invention
A kind of attached drawing 1: oil cylinder of hydraulic headstock gear structure chart.
A kind of attached drawing 2: hydraulic hoist oil cylinder piston rod end structure figure.
In attached drawing: 1-cylinder head component, 2-piston components, 3-cylinder barrels, 4-piston rods, 5-guide sleeve components, 6-is living
Rod seal part, 7-rod end small stairs, 8-small stair keyways, 9-rod end screw threads.
Specific embodiment
Shown in Figure of description 1: cylinder head component 1 links together with cylinder barrel 3, and piston component 2 is connected to piston rod 4
Together, guide sleeve component 5 links together with cylinder barrel 3.
Shown in Figure of description 1: piston rod seal component 6 is mounted on guide sleeve component 5, and piston component 2 is in cylinder barrel 3
It is axially movable, piston rod 4 passes through guide sleeve component 5 and piston rod seal component 6 is axially movable.
Shown in Figure of description 1 and Figure of description 2: rod end small stair 7 and small multiple is set on piston rod 4
Rank keyway 8.
Shown in Figure of description 1 and Figure of description 2: the outer circle of rod end small stair 7 is less than the outer circle of piston rod 4, multiple
Small stair keyway 8 is evenly arranged on rod end small stair 7.
A kind of oil cylinder of hydraulic headstock gear assembly work process: cylinder head component 1 links together with cylinder barrel 3, while piston group
After part 2 and piston rod 4 link together, piston component 2 is packed into cylinder barrel 3, and guide sleeve component 5 is worn with piston rod seal component 6
Piston rod 4 is crossed to be mounted on cylinder barrel 3, piston rod seal component 6 pass through piston rod 4 when, piston rod seal component 6 not with rod end small stair
7 contact, the possibility that piston rod seal component 6 does not scratch, and in cylinder barrel when oil inlet, piston component 2 is axially movable in cylinder barrel 3,
Piston rod 4 passes through guide sleeve component 5 and piston rod seal component 6 is axially movable, and realizes the purpose of oil cylinder bidirectional-movement.One
Kind oil cylinder of hydraulic headstock gear, rationally, sealed reliable is practical and convenient convenient for assembly for design.
