Specific implementation mode, the present invention is further explained.
- Fig. 4 is please referred to Fig.1, the present invention provides a kind of technical solution：A kind of automotive engine valves oil seal demounting device,
Including dismounting component, intermediate plate 1, screw shell 2 and connecting rod 3, screw shell 2 is mounted in 3 annular side of connecting rod, and intermediate plate 1 is logical
It crosses shaft and is mounted on 3 lower end of connecting rod.
Dismounting component includes holder 6, spring 4, connecting rod 3, external thread column 7 and gasket 8, and screw rod 5 is mounted on 6 lower end of holder
And 5 lower end of screw rod passes through holder 6 and is connected with connecting rod 3 by pin rod, 4 lower end of spring fits with 6 upper surface of holder and bullet
Spring 4 is mounted in 5 annular side of screw rod, and external thread column 7 is mounted on 6 lower face of holder, and gasket 8 is fixed on 7 lower end of external thread column,
In use, holder 6 is placed on suitable position on engine case, two groups of gaskets 8 are in contact with engine case respectively at this time, due to
Engine case is irregular shape so holder is unstable at this time, to adjust length of two groups of external thread columns 7 in tapped blind hole
Degree adjusts the distance between two groups of gaskets 8 and 6 lower end of holder until the stabilization of holder 6, rotates screw rod 5 using turntable 9, realize screw rod
5 rotate in threaded hole and realize that 5 lower end of screw rod drives connecting rod 3 to move downward, and connecting rod 3, which moves downward, drives intermediate plate 1 to transport downwards
It is dynamic, while screw rod 5 moves downward realization spring 4 and holds on the frame 6 and compressed between 9 lower end of turntable, until intermediate plate 1 moves downward
When at the diameter mouth on to valve oil seal, screw shell 2 is rotated, realizes that screw shell 2 is transported downwards along the external screw thread on connecting rod 3
Dynamic, after 2 lower end of screw shell is contacted with two groups of intermediate plates 1, screw shell 2 continues movement and two groups of intermediate plates 1 is driven to turn around shaft
Shaft rotation is dynamic, while the return spring compression between two groups of intermediate plates 1, and then two groups of 1 lower ends of intermediate plate do relative motion until valve oil
It is gripped at envelope diameter mouth, stop operating screw shell 2, rotates backward turntable 9 and realizes that screw rod 5 rotates backward, to 5 edge of screw rod
It threaded hole to move upwards, screw rod 5 moves up through connecting rod 3 and intermediate plate 1 is driven to move upwards, to realize that gas is clamped in intermediate plate 1
Door oil sealing moves upwards, while forcing screw rod 5 to have the tendency that moving upwards under the action of 4 screen resilience of spring, and gas is reduced with this
The dismounting difficulty of door oil sealing rotates backward screw shell 2 and realizes two groups of intermediate plates 1 in return bullet until valve oil seal is dismantled completely
It sets back under the action of spring, convenient for the recycling of valve oil seal and reusing for intermediate plate 1.
It is machined with external screw thread on the downside of 3 annular side of connecting rod, screw shell 2 is connected by external screw thread with connecting rod 3, due to spiral shell
Line sleeve 2 is connected by external screw thread with connecting rod 3, is occurred so as to avoid the situation that screw shell 2 arbitrarily moves.

The cross section of group intermediate plate 1 is L-type, and two groups of 1 symmetric clamp valve oil seals of intermediate plate improve clamping effect, spring 4 is designed with
Conducive to the self-return of intermediate plate 1, the cross section of L-type is stuck in convenient for intermediate plate 1 at the diameter mouth on valve oil seal.
Turntable 9 is fixed in 5 upper end of screw rod and 9 lower face of turntable is in contact with 4 upper end of spring, and screw rod 5 is rotated by turntable 9,
Reduce the rotation difficulty of screw rod 5.
The cross section of installation screw rod 5 and holder 6 is U-shaped in 6 upper surface centre position thread mill drilling of holder and threaded hole,
The design of threaded hole realizes the rotation of screw rod 5, while screw rod 5 being avoided arbitrarily to be moved under the action of 4 screen resilience of spring, reaches
The purpose of stable motion.
External thread column 7 and gasket 8 are equipped with two groups, and 6 lower face of holder symmetrically offers two groups of tapped blind holes, two groups of outer spiral shells
Line column 7 is separately mounted in two groups of tapped blind holes, and two groups of gaskets 8 are separately fixed at two groups of 7 lower ends of external thread column and two groups of gaskets 8
Rubber washer is pasted in lower end, convenient to each position valve of engine by adjusting position of the external thread column 7 in tapped blind hole
The valve oil seal at place is removed.
