Abstract
The utility model relates to an oil cylinder with a minitype adjustable cushioning device. The oil cylinder comprises a cylinder cover, a piston rod, a cylinder body and a front cushioning sleeve, wherein one side of the cylinder cover is provided with a cushion valve core, the cushion valve core is communicated with the inner cavity of the cylinder body through a pipeline, and the cushion valve core utilizes a screw plug and a combination gasket to seal and fix. The oil cylinder with the minitype adjustable cushioning device provided by the utility model has the advantages that the stability is good, the accuracy is good, the disassembly and assembly are convenient, the structure is delicate, small and compact, thereby effectively preventing the piston from heavily bumping against the cylinder cover to cause the oil cylinder to deform.
Description
Technical field
The utility model relates to a kind of oil cylinder, is specifically related to a kind of oil cylinder with Miniature adjustable damping device.
Background technique
Damping device in the past all is to be applied in the well-to-do situation of cylinder sizes, and under the state that the each side condition is fit to (very large such as cylinder barrel and piston rod distance), and afterbody is substantially all threaded, the buffering spool directly is screwed into cylinder cap and just can have played regulating action, and compression combination mat and hexagon thin nut, sort buffer device validity is not high, and afterbody is exposed easily damages outside, affects cushioning effect.Very little in the cylinder cover structure size, damping device commonly used is just inoperative.
The model utility content
The technical problems to be solved in the utility model is: for the damping device validity of oil cylinder before solving not high, easily damage, the problems such as size restrictions, the utility model provide a kind of oil cylinder with Miniature adjustable damping device, utilize to screw and unclamp the speed that plug screw is regulated the oil cylinder activity.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of oil cylinder with Miniature adjustable damping device comprises cylinder cap, piston rod, cylinder body and front cushion collar, one side of described cylinder cap is provided with the buffering spool, described buffering spool is communicated with inner chamber of cylinder block by pipeline, and described buffering spool utilizes plug screw and combination mat sealing to fix.
In order to increase hardness, described buffering spool 5 is made for 45# Hardened And Tempered Steel.
Described buffering spool 5 diameter 8mm, overall length 17mm.
The beneficial effects of the utility model are, the utlity model has the oil cylinder of Miniature adjustable device, can bear the working pressure of 25Mpa, good stability, accuracy is good, and easy disassembly and structure are exquisite, small and exquisite, compact, prevent that effectively piston from acutely clashing into cylinder cap, make the state of oil cylinder distortion.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation that the utlity model has the optimum embodiment of oil cylinder of Miniature adjustable damping device.
Among the figure 1, cylinder cap, 2, piston rod, 3, cylinder barrel, 4, front cushion collar, 5, the buffering spool.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, oil cylinder with Miniature adjustable damping device described in the utility model comprises cylinder cap 1, piston rod 2, cylinder body 3 and front cushion collar 4, one side of cylinder cap 1 is provided with buffering spool 5, buffering spool 5 is communicated with cylinder body 3 inner chambers by pipeline, buffering spool 5 utilizes plug screw and combination mat sealing to fix, buffering spool 5 is made for 45# Hardened And Tempered Steel, buffering spool 5 diameter 8mm, overall length 17mm.
Oil cylinder is in movement process, and front cushion collar 4 slowly inserts cylinder cap 1, piston rod 2 setting in motions, regulate buffering spool 5 and just can play good action effect, particularly under the state of high pressure, oil cylinder is when rapid movement, can prevent piston rod 2 violent bump cylinder caps 1, make the oil cylinder distortion.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
