As a further improvement on the present invention, it is connected through a screw thread between the guide sleeves inwall and fix bar body outer wall.
As a further improvement on the present invention, the guide sleeves inwall is provided with an annular sliding groove, an annular protrusion bar being embedded into sliding groove is provided with the slip cap.
As a further improvement on the present invention, the expansion rod central coaxial is provided with some screw holes, be fixedly connected between the slip cap and expansion rod by screw.
As a further improvement on the present invention, the elastic metallic material is steel.
The beneficial effects of the invention are as follows：
1st, the present invention passes through the expansion type uniformly moved a drag link mechanism, realize the fixation to bearing, due to being equidistant expansion, so this structure possesses self-centering ability, this structure is fixed compared to traditional expansion type simultaneously, possess certain elasticity, the fixed press to bearing inside casing can be prevented, cause the damage of bearing.
2nd, it is more stable when threaded connection is adjusted compared to other drive mechanisms.
3rd, the cooperation of sliding groove and raised item connects that piece throw is lower, and precision is higher compared to bearing.
4th, mode connects for screw is readily disassembled, and is also easier to assemble.
5th, the support inner ring and expansion outer shroud of the invention by mutually socket-connecting, opposing oscillatory can be carried out by pendular ring between the two, the spring leaf set simultaneously above and below both between both sides can ensure bearing inner wall and expand the laminating degree of outer shroud, ensure the stability that bearing clamps.

Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only illustrate the basic structure of the present invention in a schematic way, therefore it only shows the composition relevant with the present invention.
As shown in Figure 1,The present invention is a kind of expansion bearing stationary fixture,The bearing inside casing fix bar includes a fix bar main body,A crossed grooves is provided with the fix bar main body,The crossed grooves includes some expansion slots to cross one another,The expansion slot is tapered configuration along its depth direction,The width of expansion slot aperture position is more than the width of expansion trench bottom,Each expansion slot interconnects in the middle part of fix bar,The position that expansion slot is corresponded in fix bar body outer wall is additionally provided with a bearing pre-tightened ring,The bearing pre-tightened ring includes a support inner ring and an expansion outer shroud,Wherein support inner ring is made of elastic metallic,The expansion outer shroud is made of nylon,A swing gap is provided between the support inner ring and expansion outer shroud,A pendular ring is provided with the middle part of the swing gap,An annular spring leaf is each provided with the both sides up and down in the swing gap；The bearing inside casing fix bar also includes an expansion bar assembly, the expansion bar assembly includes the expansion rod of some middle parts connection fastened to each other, expansion rod is embedded into expansion slot, a slip cap is also socketed with the outside of the fix bar main body, the end of each expansion rod is fixedly connected with the inwall of slip cap, is also socketed with a guide sleeves in the fix bar body exterior, is rotatablely connected between guide sleeves and slip cap, by driving guide sleeves so that expansion rod moves along expansion slot；
