It is additionally provided with spherical groove in inner sleeve 2, the second steel ball 16 is placed in spherical groove, second steel ball 16 is not connected with inner sleeve
Side be located on guiding calvus 18 in the hole that opens up.
Its bottom end of the interior positioning head 1 is used to cover 40 positioning compression, makes the revolving body of washer 30 and capping 40
Center aligns；In process, second segment 60 and first segment 50 are successively contacted with the first steel ball 17, for controlling guide grab
The contraction of piece 18 with expand, in order to realize washer 30 push before can first expand, thus solve washer 30 and capping 40 cooperation
The problem of tension.
Further, the interior positioning head 1 is connected with third spring 15, and interior 1 side of positioning head is provided with second
Nut 13.Interior positioning head 1 realizes reset of gliding relative to pressure pad circle inner sleeve 2, by third spring 15, and the second nut 13 is for adjusting
The pretightning force of whole third spring 15.
Under normality, four guiding calvus 18 for compressing steel ball are in contraction state；When inner sleeve 2 drives guiding calvus 18 opposite
When interior positioning head 1 moves downward, the first steel ball 17 is rolled to the first segment 50 of interior positioning head 1, can make guide grab piece first
18 lower ends are opened, and play the role of expanding 30 inner hole of washer at this time.18 periphery of guiding calvus is surrounded by internal expanding core retainer plate 4.
Second steel ball 16 is equivalent to shaft, so that inner sleeve 2 is connected with guiding calvus 18, but also can be used as guide grab
The swinging support point of piece 18.The flexible Application of second steel ball 16 and the first steel ball 17, can reduce frictional resistance, in turn simplify knot
Structure.Further, there are four the second steel ball 16 and the first steel ball 17 are arranged, there are four be oriented to calvus 18 for corresponding setting.
Further, limit sleeve 5, the side of first spring 14 are provided between the internal expanding core retainer plate 4 and housing 3
The limit sleeve 5 is connected, the limit sleeve 5 has the first nut 11 and bolt 10.Inner sleeve 2 is fixedly connected with internal expanding core retainer plate 4, they
It relative to internal position limited sleeve 5, realizes and slides up and down under the action of the first spring 14, calvus fixing sleeve scotch 7 limits under them
The position fallen, 14 pretightning force of the first spring are adjusted by the first nut 11.
Further, the housing 3 is fixedly connected with fixing sleeve 6, and guide sleeve 8 is docked in 6 upper end of fixing sleeve, described
Guide sleeve 8 guides second spring 12, and the side of the second spring 12 is provided with adjusting sleeve 9, one end connection of the adjusting sleeve 9
There are two first nut 11 and a bolts 10, adjust adjustment bolt 10 by two the first nuts 11 and adjusting sleeve 9 is opposite
Position so as to adjust the pretightning force of second spring 12, and has locking function.
Further, it is provided with guide pin spring 19 at the limit sleeve 5, is provided with and leads in the guide pin spring 19
To pin 20.The limit sleeve 5 is used for after washer 30 tentatively 40 bottoms of indentation capping, pushes 30 inner circumferential of washer in place, limit
Position set 5 realizes small distance sliding up and down relative to housing 3, by guide pin spring 19, and guide pin 20 is for guide pin spring 19
It play the guiding role.
As shown in fig. 3 to 7, the course of work of pressure head assembly is as follows:
(1) initial state.Pressure head assembly is in the normal state position under spring force, as shown in Figure 1.At this point, washer 30 is located at
Right above capping 40.
(2) 40 positioning of capping.Positioning is realized in 1 pair of interior positioning head capping 40, as shown in Figure 3.Pressure head assembly integrally pushes,
Until interior 1 lower end of positioning head compresses 40 indent upper surfaces of capping.
(3) washer 30 is expanded.The guiding expansion of calvus 18 expands 30 inner hole of washer, as shown in Figure 4.Interior positioning head 1 stops
After movement, 15 active force of spring is overcome, pressure pad circle inner sleeve 2 drives rubber pad guiding calvus 18 with respect to positioning head 1 in pressure pad circle
It continues traveling downwardly to capping upper end protrusion cambered surface, at this point, the first steel ball 17 is rolled to the major diameter outer circle shell of column of interior positioning head 1 (the
One section 50), make to be oriented to the opening of calvus 18, expand to 30 inner hole of washer, washer 30 and capping 40 is avoided to cross tight fit.
(4) inclination of washer 30 press fitting.Housing 3 and limit sleeve 5 push washer 30 simultaneously, and washer 30 is in low inside and high outside inclination
State slides downwards, as shown in Figure 5.After inner sleeve 2 and guiding 18 stop motion of calvus, washer inner hole is extended, housing 3 and limit
Position set 5, overcomes the active force of the first spring 14 while running down, and pushes in washer 30 to 40 concave arc shape bottom edges of capping, due to
The height fall of housing 3 and limit sleeve 5, therefore, washer 30 slightly tilt, and 30 periphery of washer falls on the bottom of capping 40 first,
As shown in Figure 6.
(5) the smooth press fitting of washer 30.Pressure pad circle internal position limited sleeve 5, continues to push, and pushes 30 inner circumferential of washer in place, at this point,
The flat state of washer 30 is located in 40 concave arc shape bottom edges of capping, as shown in Figure 7.Housing 3 moves to after bottom, internal position limited sleeve 5
Guide pin spring 19 is compressed, continues to move downward, until its low side pushes 30 inner circumferential of washer in place, at this point, housing 3 and interior limit
Position 5 bottom ends of set are concordant, and washer 30 is in horizontal plane formation state.Second spring 12 is compressed, mitigates impact of head power.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
