Owing to different need of work samples to be carried out transmitting or move to different positions in different vacuum chamber in the vacuum system of multi-cavity room, it is thus desirable to use a kind of device being referred to as magnetic transmission machine structure. The common magnetic force transfer device of magnetic force the earliest due to internal structure unreasonable, the pure iron core in valve tube and be mechanical friction campaign completely in valve tube inwall in movable and rotary course, causes certain pollution to vacuum system, and its work-ing life is limited. Magnetic force transfer device described in patent ZL90226957.7 has carried out some at the two ends of pure iron core to be improved, it mainly adopts roller mode when axial motion, but is still that roller side and valve tube inwall carry out mechanical friction campaign completely when doing radial rotary and move. Not easily process due to valve tube inside and cause that inner surface accuracy is not high and the reason such as distortion after baking, cause Caton phenomenon transmitting and rotary course exists mechanical friction, seriously affect the alignment precision to transmission sample in transmittance process.
Summary of the invention
It is an object of the invention to: propose a kind of all can the magnetic force transfer device that almost do not rub of flexible motion in transmission lever direction and radial rotary direction.
The present invention is achieved in that
A kind of magnetic force transfer device, comprise transmission valve tube, and it is arranged on the pure iron core slide assemblies transmitted in valve tube, described pure iron core slide assemblies comprises roller, roller shaft, rolling wheel support and pure iron core, roller is connected with rolling wheel support by roller shaft, the two ends of described pure iron core are provided with stationary shaft, described rolling wheel support is provided with axis hole along the axial direction due transmitting valve tube, stationary shaft stretches in the axis hole of rolling wheel support, its special character is: be provided with spot contact bearing between the axis hole of described rolling wheel support and stationary shaft, the outer shroud of spot contact bearing is fixedly connected with the axis hole of rolling wheel support, the inner ring of spot contact bearing and stationary shaft wringing fit.
Above-mentioned pure iron core is provided with groove along the central axial direction transmitting valve tube.
Above-mentioned spot contact bearing is enclosed spot contact bearing.
The quantity of above-mentioned groove is 6.
Above-mentioned rollers support is four rolling wheel supports.
The mode that is fixedly connected with between the outer shroud of above-mentioned spot contact bearing and rolling wheel support adopts the mode that pin and pin hole match.
It is an advantage of the invention that:
(1) magnetic force transfer device of the present invention adopts the mode of roller when transmission lever carries out axial motion, also bearing mode is adopted when rotating, almost there is no mechanical friction, therefore, the operation when transmitting sample and carry out contraposition of this magnetic force transfer device is more flexible, aligning accuracy improves greatly, extends the work-ing life of magnetic force transfer device simultaneously.
(2) pure iron core is provided with groove in the axial direction so that the torsion that pure iron core is subject to is bigger.
