Under the action of be squeezed and deformed, swelling is in the inner ring in gear ring.
It is convenient to pick and place workpiece for the fixture of this gear ring clamping, high degree of automation, but to be directly used in internal diameter
The clamping of biggish gear ring then needs pull rod to provide very big pulling force, enough deformation forces could be provided for resilient sleeve, will lead to
Using pull rod service life reduction, the frock clamp cost is caused to increase indirectly, that is, this gear ring clamping tooling is not suitable for pair
The biggish gear ring of internal diameter carries out clamping；In addition, being also real by resilient sleeve swelling in this fixture, between resilient sleeve and outer frustum
Existing resilient sleeve positions completely, and reliability is not high enough.
Summary of the invention
For the deficiency in the presence of the prior art, the main purpose of the utility model is that optimizing existing gear ring clamping work
Dress makes to be suitable for the biggish gear ring progress clamping of internal diameter, and improves the reliability of entire tooling.
The gear ring clamping tooling of the utility model adopts the following technical scheme that：
A kind of gear ring clamping tooling, including being used to support the positioning disk of gear ring, the pedestal for installing support positioning disk, passing through
Wear the pull rod of pedestal, for gear ring to be pressed on positioning disk upper press cover and is used for the elastic component of swelling positioning gear ring inner hole, it is described
Pedestal is convexly equipped with a centralized positioning axis, which is set to the centralized positioning axis periphery, and the elastic component is revolving body, should
Elastic component includes the round plate for being placed on pull rod periphery and the wedge-shaped part for being integrally disposed upon round plate periphery, the outer rim of the elastic component
Several notches for being used to divide wedge-shaped part are circumferentially evenly equipped with, which is arranged pull head, which is provided with
With the chamfering of wedge-shaped part cooperation, the wedge-shaped part is in swelling under the drive of pull head between centralized positioning axis and gear ring inner hole；Institute
The stop pin being equipped in notch for preventing elastic component from rotating is stated, which is inserted into centralized positioning axial end.
Further, it is equipped with screw-thread bush on the pull rod, round plate is located between pull head and screw-thread bush.
The beneficial effects of the utility model：
The gear ring clamping tooling of the utility model divides wedge-shaped part using notch, so that wedge-shaped part only needs lesser power just
It can deform, the biggish gear ring of internal diameter can be suitable for.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing gear ring clamping tooling；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of elastic component in Fig. 2；
Fig. 4 is the top view of Fig. 3.
Appended drawing reference in Figure of description includes：Gear ring A, positioning disk 1, pedestal 2, pull rod 3, gland 4, elastic component 5, spiral shell
Line bushing 6, stop pin 7, centralized positioning axis 21, pull head 31, round plate 51, wedge-shaped part 52, notch 53.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
Referring to fig. 2, Fig. 3, Fig. 4, a kind of gear ring clamping tooling, including being used to support the positioning disk 1 of gear ring A, for installing
Support positioning disk 1 pedestal 2, through the pull rod 3 of pedestal 2, for gear ring A to be pressed on 1 upper press cover 4 of positioning disk and is used for swelling
The elastic component 5 of gear ring inner hole is positioned, the pedestal 2 is convexly equipped with a centralized positioning axis 21, and it is fixed which is sheathed on the center
21 periphery of position axis, the elastic component 5 are revolving body, which includes being placed on the round plate 51 of 3 periphery of pull rod and integrally setting
The wedge-shaped part 52 in 51 periphery of round plate is set, the outer rim of the elastic component 5 is circumferentially evenly equipped with several for dividing lacking for wedge-shaped part 52
Pull head 31 is arranged in mouth 53,3 end of pull rod, which is provided with the chamfering cooperated with the wedge-shaped part 52, should
Wedge-shaped part 52 is in swelling under the drive of pull head 31 between centralized positioning axis 21 and gear ring A inner hole.
Referring to fig. 2 and Fig. 4, the stop pin 7 for preventing elastic component 5 from rotating is equipped in the notch 53, this is anti-
It ships and resell on another market 7 insertion centralized positioning axis, 21 end face.The stop pin 7 can prevent elastic component 5 from rotating in process, thus anti-
Only gear ring rotates with it, so that the gear ring clamping tooling of the utility model is using more reliable.
When clamping, first gear ring A is placed on positioning disk 1, pulls pull rod 3, pull head 31 drives elastic component 5 towards 2 institute of pedestal
Mobile in direction, so that wedge-shaped part 52 is attached to the chamfering surface of centralized positioning axis 21, increasingly tighter wedging gear ring A inner hole is in
Between heart locating shaft 21, and deformation occurs, so that swelling in gear ring A inner hole, to gear ring A Internal hole positioning, then drives gland 4
It is pressed on the end face gear ring A, i.e. completion clamping.
The gear ring clamping tooling of the utility model divides wedge-shaped part 52 using notch 53, so that 52 need of wedge-shaped part are smaller
Power can deform, the biggish gear ring of internal diameter can be suitable for.
In the embodiment that one optimizes, referring to fig. 2, screw-thread bush 6, round plate 51 are equipped on the pull rod 3
It is located between pull head 31 and screw-thread bush 6.It may make after processing is completed, elastic component 5 can take off under the drive of screw-thread bush 6
Gear ring A inner hole out；And the screw-thread bush 6 is set, enables to the distance between screw-thread bush 6 and pull head 31 adjustable, also
Be can the elastic component different to thickness install, can be suitable for more polytypic gear ring clamping.
While there has been shown and described that the embodiments of the present invention, it will be understood by those skilled in the art that：
These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective
And modification, the scope of the utility model are defined by the claims and their equivalents.
