Specific embodiment
Below in conjunction with drawings and Examples, the technical characteristic above-mentioned and other to the present invention and advantage make more detailed
Thin explanation.
A kind of blind hole bearing withdrawing device of the present invention, as depicted in figs. 1 and 2, the blind hole bearing takes out dress
Put including：Tightening sleeve 1, guide head 2, push rod 3, extension tube 4 and fresh idea 5, wherein：
The fresh idea 5 is thin-walled tubular structure, including tubular body 51 and by one end axle of tubular body 51
To multiple clamping jaws of the circumferentially spaced arrangement for extending out, each clamping jaw includes sequentially integrally connected：With
Divergent segment 53 that the connected flat segments 52, outer diameter of tubular body 51 gradually expand, continue vertically to
The latter end 54 of outer extension and bent radially inward by the end of latter end 54 and extend the hook tooth 55 that is formed；Institute
The other end outer wall for stating tubular body 51 is provided with external screw thread, and inwall is provided with internal thread；
The tightening sleeve 1 is linked in the outside of the fresh idea 5, and its one end is provided with internal thread, can be with the pipe
The external screw thread of shape main body 51 is connected, and the other end is withstood on the divergent segment 53 of the clamping jaw；
One end of the extension tube 4 is provided with external screw thread, and the screw-internal thread fit with the tubular body 51 is connected,
The other end is provided with the internal thread consistent with the dimension of inner screw thread of the tubular body 51；
The guide head 2 is provided with external screw thread, and the screw-internal thread fit with the extension tube 4 is connected, the guiding
First 2 center is additionally provided with internal thread hole；
The push rod 3 is provided with external thread section along its length, coordinates with the internal thread hole of the guide head 2 and connects
Connect, can extend into and more than the extension tube 4 and the certain length of fresh idea 5 (in order to prevent in Fig. 1, Fig. 2
Scale of view is too small to cause details to obscure, and the ratio physical length that the length of push rod 3 is drawn is short).
When use, blind hole bearing withdrawing device is assembled first, the tightening sleeve 1 withstands on the folder
The less position of external diameter of the divergent segment 53 of pawl, during blind hole bearing withdrawing device then stretched into blind hole, until
Clamping jaw offsets with the inner ring of bearing 6, continues deeper into blind hole, the hook tooth 55 of clamping jaw is crossed bearing by elasticity
6 inner ring outside thicker part divides and catches on the ball grooves in the middle part of inner ring (as shown in Figure 2), next turns receipts
Tight set, makes tightening sleeve 1 gradually withstand the larger position of external diameter of the divergent segment 53 of the clamping jaw, now, folder
The divergent segment 53 of pawl is gradually tightened up under the thrust of tightening sleeve 1, so as to the inner ring of bearing 6 tightly be clasped,
Cannot release；Next, turning push rod 3, the tip of push rod 3 is set to withstand on the endoporus spindle nose of bearing 6, so
After continue to turn push rod 3, bearing 6 is taken out from blind hole by reaction force.Take out after bearing 6, revolve
The pine tightening sleeve 1, clamping jaw recovers original elasticity, you can bearing 6 is taken off from clamping jaw.
Referring again to shown in Fig. 3, be by the removal of extension tube 4, the external screw thread of guide head 2 directly with tubulose master
The screw-internal thread fit connection of body 51, other structures and previous embodiment all same, using the structure shown in Fig. 3,
It is adapted to the less situation of blind hole depth.That is, user can select to use or uncomfortable with ablepsia hole situation
With the extension tube 4.
Operate for convenience, the fresh idea, tightening sleeve, extension tube and guiding head surface make annular knurl treatment,
And be preferably made of spring steel.
It is described above to be merely exemplary for the purpose of the present invention, and nonrestrictive, ordinary skill people
Member understand, in the case where the spirit and scope that claim is limited are not departed from, can many modifications may be made,
Change is equivalent, but falls within protection scope of the present invention.
