Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-15 is please referred to, the utility model provides a kind of technical solution: a kind of expanding mechanism of O-ring group kludge,
Including claw 4 and O-ring lasso centrum 11, claw 4 is fixed by collet flange 3 and collet axis 2, and is nested on collet axis 2
Second spring 13, the quantity of claw 4 is six, and the first spring 12 is provided on claw 4, and claw 4 passes through the first spring
12 constitute elastic bascules, this make O-ring 14 when being expanded by claw 4 can with uniform stressed, so as to uniform expansion,
So that O-ring 14 is not easy to be pulled bad, claw 4 passes through collet flange 3, collet axis 2, pushing slide plate 1, moveable combination of guide rod 5 and expansion
Cylinder 6 constitutes vertical lift bascule, this makes claw 4 can be by the driving automatic lifting of expansion cylinder 6, and in lifting
Stable plumbness can be kept in the process, the offset of position will not occur, and O-ring lasso centrum 11 is solid by fixing sleeve 9
It being scheduled in fixed plate 7, and fixed plate 7 is located at immediately below collet axis 2, O-ring lasso centrum 11 is internally provided with third spring 15,
And 15 lower end of third spring is provided with steel ball 17, O-ring lasso centrum 11 constitutes elastic bascule by third spring 15, this
Allow to reduce upper flitch 21 in moving process, the frictional force between O-ring lasso centrum 11 and upper flitch 21 reduces and expands
In-house parts depreciation degree is opened, so that the service life of the expanding mechanism of O-ring group kludge increases, so that cost is reduced,
Collet axis 2, which is fixed on, to be pushed on slide plate 1, and is pushed 1 two sides of slide plate and be nested in moveable combination of guide rod 5, and pushes 1 upper end of slide plate company
It is connected to expansion cylinder 6, O-ring 14 is provided on O-ring lasso centrum 11, and the side of O-ring lasso centrum 11 is provided with and determines
Position pin 18, and end is provided with screw 20 after positioning pin 18, the 5th spring 19 is nested on positioning pin 18, and positioning pin 18 is logical
It crosses the 5th spring 19 and constitutes elastic bascule, this makes in expanded position, and the 4th spring 16 does not generate compressive deformation, still
When leaving this position to assembled position with plug screw, positioning pin 18 is headed on without part, O-ring lasso centrum 11 can on
Lower movement facilitates the assembling for carrying out O-ring 14 and plug screw, and 11 lower end of O-ring lasso centrum is provided with sliding axle 10, and sliding axle
It is nested with the 4th spring 16 on 10, upper flitch 21 is provided with below fixed plate 7, and 21 lower end of upper flitch is provided with bearing block 8.
Working principle: when using the expanding mechanism of the O-ring group kludge, O-ring 14 is fed cylinder and shifts O onto first
On type snare circle centrum 11, then expansion cylinder 6 is advanced downwardly, so that pushing the parts such as slide plate 1, collet axis 2 and claw 4 together
It moves downward along moveable combination of guide rod 5, just can not after the end of the mandrel of collet axis 2 and the groove contact of O-ring lasso centrum 11
Continue downwards, and 6 claws 4 can continue downwards, expand O-ring 14 downwards along the tapered segment of O-ring lasso centrum 11,
In this process, the first spring 12 mainly plays a firm effect, the bottom of O-ring lasso centrum 11 to the expansion of 6 claws 4
There are 5 holes in portion, and inside is felt relieved equipped with third spring 15 and steel ball 17, intermediate steel ball 17 main and positioning action, and the 4 of surrounding
A steel ball 17 is mainly reduced in 21 moving process of upper flitch, the frictional force of O-ring lasso centrum 11 and upper flitch 21, claw 4
Continuing downwards, third spring 15 is compressed, so that the bottom of O-ring lasso centrum 11 and the top of upper flitch 21 are in contact, it is O-shaped
Circle 14 enters in the hole of upper flitch 21, encloses in the outer circle of 11 lower end of O-ring lasso centrum, in this position, due to screw
20 ends outstanding are moved to the left positioning pin 18, are stuck in the lower part of the outer circle of 11 lower end of O-ring lasso centrum, therefore the 4th
Spring 16 does not generate compression；Like this, O-ring completes O by expansion circle in the outer circle of 11 lower end of O-ring lasso centrum
The expansion of type circle, the above are the use processes of the expanding mechanism of the O-ring group kludge.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
