Abstract
The utility model discloses a kind of valve oil seal driver, comprise jumper bar, jumper bar comprises upper straight rod, tapered pole and lower straight-bar and forms, ring set is set with outside upper straight rod, the upper surface of tapered pole is pushed down in the lower surface of ring set, upper straight rod above ring set is set with backplate, and the end of upper straight rod is provided with the attacking head of hat, and described backplate is pushed down in attacking head lower surface; Lower straight-bar is connected with the cylindrical shell under shed, and the center of cylindrical shell is run through locating shaft that stretch into lower straight-bar, that match with valve oil seal.The utility model novel in structural design is reasonable, by the cooperation of various piece, fast valve oil seal can be squeezed into engine installation position, improves efficiency and the quality of assembling.
Description
technical field:
The utility model relates to engine assembling, particularly relates to a kind of valve oil seal driver.
background technology:
Valve oil seal can prevent machine oil from entering air inlet-outlet pipe, causes machine oil to run off, and prevents the mist of gasoline and air and discharging waste gas from leaking, prevents engine motor oil from entering combustion chamber.
Valve oil seal is one of strength member of engine valve group, at high temperature contacts with gasoline and machine oil, therefore needs to adopt heat resistance and the excellent material of oil resistivity, is generally fluorubber and makes.
Squeeze in the process of assembling for engine valve oil seal, previously often occurred that valve oil seal was impaired squeezing in process, sealing does not reach the demand of environment for use, has a strong impact on the service life of engine.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of valve oil seal driver, fast valve oil seal can be squeezed into engine installation position, improves efficiency and the quality of assembling.
The technical solution of the utility model is as follows:
Valve oil seal driver, it is characterized in that: comprise jumper bar, described jumper bar comprises upper straight rod, tapered pole and lower straight-bar and forms, ring set is set with outside upper straight rod, the upper surface of tapered pole is pushed down in the lower surface of ring set, upper straight rod above ring set is set with backplate, and the end of upper straight rod is provided with the attacking head of hat, and described backplate is pushed down in attacking head lower surface; Described lower straight-bar is connected with the cylindrical shell under shed, and the center of cylindrical shell is run through locating shaft that stretch into lower straight-bar, that match with valve oil seal.
Described valve oil seal driver, is characterized in that: described lower straight-bar outer wall is provided with radial locking pin, and described locating shaft is withstood in locking pin front end.
Described valve oil seal driver, is characterized in that: described cylinder body outer wall is set with heat-shrink tube.
The utility model has the advantages that:
The utility model novel in structural design is reasonable, by the cooperation of various piece, fast valve oil seal can be squeezed into engine installation position, improves efficiency and the quality of assembling.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
See accompanying drawing:
Valve oil seal driver, comprise jumper bar 1, jumper bar 1 comprises upper straight rod 1-1, tapered pole 1-2 and lower straight-bar 1-3 is formed, ring set 2 is set with outside upper straight rod 1-1, the upper surface of tapered pole is pushed down in the lower surface of ring set 2, upper straight rod 1-1 above ring set 2 is set with backplate 3, and the end of upper straight rod 1-1 is provided with the attacking head 4 of hat, and backplate 3 is pushed down in attacking head 4 lower surface; Lower straight-bar 1-3 is connected with the cylindrical shell 5 under shed, and the center of cylindrical shell 5 is run through locating shaft 6 that stretch into lower straight-bar, that match with valve oil seal.
Lower straight-bar 1-3 outer wall is provided with radial locking pin 7, and locating shaft 6 is withstood in locking pin 7 front end, fast valve oil seal can be squeezed into engine installation position, improves efficiency and the quality of assembling.
Cylindrical shell 5 outer wall is set with heat-shrink tube 8.
