In as a preferred technical scheme, it is provided with card ball disk rotating bar 12 on card ball disk 3, is provided with nut on nut 7
Rotating bar 13.
Card ball disk rotating bar 12, card ball are symmetrically fixedly connected with by circumferential edges region two sides on 3 upper surface of card ball disk
It is oblique between disk rotating bar 12 and card ball disk 3 to be fixedly connected, when card ball disk rotating bar 12 rotates, and card ball disk 3 is driven to rotate, because
For the relationship of card ball disk 3 and the socket of 2 screw thread of threaded post, so that ball head stay 4 and card ball disk when card ball disk 3 rotates
3 occur relative torsion, certain displacement are moved up on card ball disk 3 while threadingly column 2, so that ball head stay 4 is located at card ball disk 3
One end lift certain angle so that ball head stay 4 further receive it is short.
It is cased with nut 7 in the threaded post 2 of 3 upper end of card ball disk, is respectively fixedly connected with obliquely in the symmetrical side of nut 7
One nut rotating bar 13, when rotating nut rotating bar 13, the rotation of nut rotating bar 13 drives nut 7, and threadingly column 2 is axial
Vertical shift.
In as a preferred technical scheme, the circumference of ball head stay 4, universal sliding sleeve 5, arc fagging 6 along card ball disk 3 is equal
Even setting.Several spherical concave surface 8(this programme are provided with using 8 groups in the outer peripheral surface even circumferential of card ball disk 3).
In as a preferred technical scheme, be cased with washer 14 positioned at the bottom of threaded post 2 on card ball disk 3, when card ball disk 3 to
Under be moved to when being adjacent to washer 14, ball head stay 4 is in horizontality.The bottom of threaded post 2 is cased with washer on firm banking 1
14, washer 14 is fixedly connected with firm banking 1, and when card ball disk 3, which is moved downward to, is adjacent to washer 14, ball head stay 4 is in water
Level state, rotating nut rotating bar 13 moves down nut 7 to compress card ball disk 3 at this time, then the elongation of ball head stay 4 to longest and
Card ball disk 3 is in stationary state.
Universal connection between ball head stay 4 and card ball disk 3 cooperates the universal company between universal sliding sleeve 5 and firm banking 1
Ball head stay 4 can be made in the rotation by, which connecing, makes universal sliding sleeve 5 that ball head stay 4 be cooperated arbitrarily to be swung, while bulb
Strut 4 can be in the universal 5 random telescopic slide in inside of sliding sleeve when swinging, and even circumferential is distributed when the rotation of card ball disk 3
All ball head stays 4 it is synchronous simultaneously twisted by universal connection with card ball disk 3, synchronize the front end of ball head stay 4
Extend and receive short, the synchronous expansion of the circumference outer diameter of 4 front end end of ball head stay composition and diminution.When ball head stay 4 is in level
When state, ball head stay 4 is vertical with card ball disk 3, the protruding longest of ball head stay 4, makes bulb as card ball disk 3 rotates
Strut 4 occurs to twist relatively with card ball disk 3, the ball head stay when twisting keeps the angle between card ball disk 3 and ball head stay 4 smaller
4 is protruding most short, and the twisting between ball head stay 4 and card ball disk 3 has range, and when reaching the limit of value, card ball disk 3 cannot
Continue to twist.
When there is roundness deformation in quenched bearing outer ring 15, wherein symmetrical both ends occur narrow and with its horizontal plane
Upper vertical other both ends occur elongating when being deformed into elliptical trend, need pair narrowed with the present apparatus to bearing outer ring 15
Title both ends, which shore, prevents its deformation, and bearing outer ring 15 is placed in device periphery, and ball head stay 4 is in receipts in the present apparatus at this time
Short status rotates card ball rotating bar, and when being moved downward to card ball disk 3 to be adjacent to washer 14, ball head stay 4 is in horizontality,
Rotating nut rotating bar 13 makes nut 7 move down compression card ball disk 3 at this time, then the elongation of ball head stay 4 to longest and card ball disk 3
In stationary state.Ball head stay 4 is made by arc fagging 6 to carry out shoring fixation bearing outer ring 15 until outside bearing at this time
15 sizing of circle.When the bearing outer ring 15 different for internal diameter, when card ball disk 3 is not displaced downwardly to bottommost just can be to bearing outer ring 15
When inside is shored, rotating nut rotating bar 13, which makes nut 7 move down compression card ball disk 3, can equally make card ball disk 3 fixed,
Ball head stay 4 shores 15 inner wall of bearing outer ring simultaneously.
The innovative point and beneficial effect of the utility model at least that:
1. card ball 3 even circumferentials of disk are universal to be connected with ball head stay 4, and corresponds to each ball head stay 4 on firm banking 1
Universal hinging has universal sliding sleeve 5, and rotation card ball disk 3 enables to ball head stay 4 while synchronizing through universal connection and card ball disk 3
It twists, the elongation and receipts for keeping the front end of ball head stay 4 synchronous are short, and the circumference outer diameter of 4 front end end of ball head stay composition is same
Step expands and reduces, and facilitates shoring and taking out for bearing outer ring 15, simultaneously because ball head stay 4 has flexible elongated and receives short spy
Property can make device be suitable for the different size of bearing outer ring 15 of internal diameter.
2. carrying out screw thread socket by threaded post 2 and card ball disk 3, ball head stay 4 into one can be made in effective range
Step is received short.
3. being cased with nut 7 in the threaded post 2 of 3 upper end of card ball disk, card ball disk 3 can be carried out when nut 7 rotates down
It is fixed, enables card ball disk 3 to control ball head stay 4 and the completion of bearing outer ring 15 is shored.
4. universal connection between 4 other end of ball head stay and arc fagging 6, allows arc fagging 6 in the process of shoring
According to the actual situation automatic capturing angle shored.
5. the upper and lower ends in 3 periphery of card ball disk are provided with to intermediate stretching outstanding along 9, the effect stretched out along 9 is
A degree of limit is arranged to vertical direction in the universal hinging of card ball disk 3 to ball head stay 4.So that on card ball disk 3
Ball head stay 4 will not reverse in the vertical direction during lower adjustment, keep relative stability.
6. respectively symmetrically oblique on card ball disk 3 and nut 7 be fixedly connected with card ball disk rotating bar 12 and nut rotating bar
13, rotation control can be carried out to card ball disk 3 and nut 7.
7. the outer mold surface of arc fagging 6 is curved surface arc, it can just be bonded the inner wall of bearing outer ring 15.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
