Abstract
The utility model discloses an oil cylinder seal assembling guiding device, particularly relates to a guiding device for the assembling an oil cylinder piston seal and a cylinder barrel, and aims to solve the technical problem that during the assembling of the oil cylinder piston seal and the cylinder barrel, the oil cylinder piston seal is difficult to mount or is easy to be damaged. The guiding device comprises a tubular outer wall and a cylindrical inner hole formed by surrounding the tubular outer wall, a step matched with an oil cylinder port is arranged on the tubular outer wall, and a conical chamfer angle is arranged at the outer end of the cylindrical inner hole. After adoption the structure, the guiding device enables the piston seal to be mounted into the cylinder barrel smoothly, so that damage to the seal due to an edge angle of the cylinder barrel is avoided, thereby improving the product quality and the production efficiency of a hydraulic cylinder.
Description
Technical field
The utility model relates to a kind of hydraulic jack assembling device, is specifically related to a kind of guiding device assembling for oil cylinder piston sealing and cylinder barrel.
Background technology
When piston seal and cylinder barrel assemble, particularly large-scale workpiece, in the situation that making both centerings without equipment special, is difficult to pack into or easily damages and seal; When having equipment by both centerings, sometimes because screw thread path and the internal diameter of cylinder of cylinder mouth differ less, thereby but seal exists larger elasticity interference to cause bad seals.Solve this assembly problem, for improving hydraulic jack product quality and production efficiency, have great significance.
Utility model content
The technical problems to be solved in the utility model is piston seal and cylinder barrel while assembling, and is difficult to pack into or easily damages sealing, provides a kind of piston seal that makes to pack smoothly cylinder barrel into, avoids cylinder barrel corner angle sealing to be caused to the cylinder seal assembling guiding device of damage.
For achieving the above object, the utility model adopts following technical proposals: a kind of cylinder seal assembling guiding device, the cylinder endoporus that comprises outer tubular wall and surrounded by outer tubular wall, outer tubular wall is provided with the step matching with oil cylinder mouth, and the outer end of cylinder endoporus is provided with conical chamfering.
The coniform chamfering of described cylinder endoporus and the outer end of cylinder endoporus is passed through round-corner transition.
The described diameter of cylinder endoporus is identical with the internal diameter of assembled cylinder tube.
Described chamfering is less than or equal to 15 °.
Described radius of corner is 10-200mm.
Described step has 1 rank at least.
The inwall of described outer tubular wall, corners and fillets inner wall roughness are 0.8-3.2.
Described outer tubular wall is structure as a whole or the symmetrical structure of line centered by slot.
Adopt the utility model after said structure to make piston seal pack smoothly cylinder barrel into, avoid cylinder barrel corner angle to cause damage to sealing, thereby improve hydraulic jack product quality and production efficiency.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the piston rod 7 shank diameters of the assembling use status architecture schematic diagrames while being greater than piston rod bar portion diameter.
Fig. 3 is the piston rod 7 shank diameters of the assembling use status architecture schematic diagrames while being less than piston rod bar portion diameter.
The specific embodiment
As shown in Figure 1, the cylinder endoporus 2 that the utility model comprises outer tubular wall 1 and surrounded by outer tubular wall 1, outer tubular wall 1 is provided with the step 3 matching with oil cylinder mouth, and the outer end of cylinder endoporus 2 is provided with conical chamfering 4.
Described cylinder endoporus 2 passes through fillet 5 transition with the chamfering of the outer end of cylinder endoporus 24.The diameter of cylinder endoporus 2 is identical with the internal diameter of cylinder of assembled oil cylinder, and larger matched in clearance is convenient to assembling, and length is joined with the oil cylinder internal diameter assembling.Chamfering 4 is less than or equal to 15 °, and chamfering length is suitably long to be convenient to assembling and at least to make great Kou Chu be greater than the external diameter of piston seal to be assembled.Described fillet 5 radiuses are 10-200mm.Optimum is 90-110 mm, and fillet 5 is the transition of cylinder endoporus 2 and outer chamfer 4, and the radius of fillet 5 is suitably convenient to greatly assembling.Radius can be 10mm, 50mm, 90mm, 100mm, 110mm, 150mm, 200mm etc.
Described step 3 has 1 rank at least, form fit with cylinder mouth, the amount doesn't matter according to actual conditions, as being 1 rank, 2 rank, 3 rank, 4 rank, 5 rank, it is spacing and control while taking out that end step 6 in outer tubular wall 1 is mainly used in length, for ease of processing and use, the outer diameter of outer tubular wall 1 and hydraulic cylinder port are matched in clearance.The inwall of described outer tubular wall 1, fillet 5 and chamfering 4 inner wall roughness are 0.8-3.2, and such roughness has guaranteed that neither processing is convenient to again in damage sealing.
Described outer tubular wall 1 is structure as a whole or the symmetrical structure of line centered by slot 13.When shank 72 diameters of the piston rod 7 assembling are greater than piston rod bar portion 71 diameter, assembly technology need to first be installed cylinder cap 8 parts such as grade, under this operating mode, this device completes after other all manufacturing procedures, by Wire EDM or the less methods such as metal saw of thickness, by the utility model, along the symmetrical subdivision of slot 13, be two parts, these two parts can take out smoothly after Piston assembling completes, and do not delay production efficiency.Symmetry is processed as two parts and uses, and can expand the scope of application of utility model; When piston rod shank 72 diameters of assembling are less than piston rod bar portion 71 diameters or other and are conducive to use, this device does not carry out subdivision, as a global facility, can gain in strength, easy to use and reduction realizes cost.
During use, when piston rod 7 shank 72 diameters of assembling are greater than piston rod bar portion 71 diameter, as shown in Figure 2, by normal assembly technology, cylinder cap 8 is arranged on piston rod 7, and piston 12, piston seal 11 and other part etc. are installed are become piston rod assembly, then the utility model guiding device 9 is arranged on to cylinder barrel 10 cylinder mouth ends, again by piston rod assembly integral body successively by coniform chamfering 4, round-corner transition 5 and cylinder endoporus 2, enter in cylinder barrel, then from cylinder barrel 10, extract guiding device 9, separately can take out, just can carry out postorder assembly work; If undressed slot 13 carries out subdivision, due to stopping of cylinder cap 8, guiding device cannot be taken off from piston rod.
When piston rod 7 shank 72 diameters of assembling are less than piston rod bar portion 71 diameter, as shown in Figure 3, assembly technology is at the inner piston 12 of installing of piston rod, piston seal 11 and other part etc. become piston rod assembly, now without cylinder cap 8 is installed, then the utility model guiding device 9 is arranged on to cylinder barrel 10 cylinder mouth ends, again by piston rod assembly integral body successively by coniform chamfering 4, round-corner transition 5 and cylinder endoporus 2, enter in cylinder barrel, then from cylinder barrel 10, extract guiding device 9, integral body can be taken out from piston rod shank outer end, cylinder cap 8 is finally installed from piston rod shank outer end to be assembled.This situation can not processed slot 13.
