Abstract
The utility model discloses a kind of guider be convenient to cylinder seal part and installed, comprise guiding tapered sleeve (1), described guiding tapered sleeve (1) is tubulose, and its cylindrical one end arranges the transition guiding conical surface, and in it, the bar portion external diameter size of circular diameter and oil cylinder piston (2) matches.The utility model adopts one both convenient installations, the auxiliary guiding tapered sleeve of seal can not be damaged again, by the conical surface of a transition, expand seal endoporus to the size identical with oil cylinder piston external diameter uniformly, by entering into seal after piston external diameter, groove being installed, after being in place, guiding tapered sleeve being removed.Installation process is time saving and energy saving, causes damage hardly to seal.The utility model structure is simple, making is easy, easy and simple to handle, effectively can improve maintenance of equipment efficiency and quality, reduction production cost.
Description
Technical field
The utility model belongs to mechanical equipment technical field, be specifically related to a kind of structure simple, make easily, be convenient to the guider that cylinder seal part is installed.
Background technology
The Yx RunddichtringO that four-roller crusher oil cylinder piston seal is mainly installed back-to-back by two forms.In prior art, at repairing four roller Oil cylinder, change in the process of oil cylinder piston seal, because piston external diameter is greater than the internal diameter of seal, need during installation, with bottle opener, seal Bian Qiao frontier fortress is expanded inner seal diameter, until install in groove by seal just can be entered after piston external diameter.In installation process, bottle opener easily damages seal lip limit, makes cylinder seal deleterious, affects repair quality.For this reason, develop a kind of be convenient to cylinder seal part install, reduce seal damage guider tool be of great significance.
Utility model content
The purpose of this utility model be to provide a kind of easy and simple to handle, can effectively improve maintenance of equipment efficiency and quality, reduction production cost be convenient to the guider that cylinder seal part installs.
The purpose of this utility model is achieved in that and comprises guiding tapered sleeve, and described guiding tapered sleeve is tubulose, and its cylindrical one end arranges the transition guiding conical surface, and in it, the bar portion external diameter size of circular diameter and oil cylinder piston matches.
The utility model adopts one both convenient installations, the auxiliary guiding tapered sleeve of seal can not be damaged again, this auxiliary guiding tapered sleeve is by the conical surface of a transition, expand seal endoporus to the size identical with piston external diameter uniformly, by entering into seal after piston external diameter, groove being installed, after being in place, guiding tapered sleeve being removed.This device is not only only applicable to the installation of four roller Oil cylinder seals, be also applicable to the installation of the cylinder seal part with similar structures, and installation process is time saving and energy saving, causes damage hardly to seal.The utility model structure is simple, making is easy, easy and simple to handle, effectively can improve maintenance of equipment efficiency and quality, reduction production cost.The utility model structure simply, easily makes, easy and simple to handle, effectively can improve maintenance of equipment efficiency and quality, reduction production cost.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model;
Fig. 2 is the seal installation process schematic diagram of prior art;
Fig. 3 is the seal installment state schematic diagram of the utility model;
In figure: 1-leads tapered sleeve, 2-oil cylinder piston, 3-seal.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but limited the utility model never in any form, based on any conversion that the utility model training centre is done, all falls into the utility model protection domain.
As shown in Figures 1 to 3, the utility model comprises guiding tapered sleeve 1, and described guiding tapered sleeve 1 is tubulose, and its cylindrical one end arranges the transition guiding conical surface, and in it, the bar portion external diameter size of circular diameter and oil cylinder piston 2 matches.
The external diameter of described guiding tapered sleeve 1 is identical with the external diameter that the groove of oil cylinder piston 2 is takeed on.
The endoporus of described guiding tapered sleeve 1 coordinates with the bar portion crest clearance of oil cylinder piston 2, and the two gap is 0.2 ~ 0.3mm.
The cone angle of the transition guiding conical surface of described guiding tapered sleeve 1 is 15 ~ 30 °.
The transition guiding conical surface of described guiding tapered sleeve 1 is connected with arc transition between its external cylindrical surface.
Microcephaly's wall thickness of the transition guiding conical surface of described guiding tapered sleeve 1 is 0.5 ~ 1mm, end chamfering, arc transition.
Outside described guiding tapered sleeve 1, edge roughness is 3.2 ~ 1.6.
operation principle of the present utility model and the course of work:
The utility model adopts one both convenient installations, the auxiliary guiding tapered sleeve of seal can not be damaged again, this auxiliary guiding tapered sleeve is by the conical surface of a transition, expand seal endoporus to the size identical with piston external diameter uniformly, by entering into seal after piston external diameter, groove being installed, after being in place, guiding tapered sleeve being removed.The utility model is not only only applicable to the installation of four roller Oil cylinder seals, be also applicable to the installation of the cylinder seal part with similar structures, and installation process is time saving and energy saving, causes damage hardly to seal.
Below to install four-roller crusher oil cylinder piston seal for embodiment, further illustrate operation principle of the present utility model and the course of work, according to four roller Oil cylinder diameter of piston rod and piston diameters, processing an external diameter is 232mm, internal diameter is 200mm, and overall width is that the guiding of 70mm assists tapered sleeve.Before installation oil cylinder piston sealing ring, guiding tapered sleeve is first in place, then sealing ring is loaded, ring inner hole is expanded to the size identical with piston external diameter uniformly by the conical surface of the tapered sleeve that leads, then sealing ring is pushed and install in groove, the tapered sleeve that finally will lead is removed, and completes whole installation process.
The utility model has structure and simply, easily makes, feature easy and simple to handle, effectively can improve maintenance of equipment efficiency and quality, reduction production cost.
