In multi-chamber vacuum system, because different need of work samples will transmit or move to different positions in different vacuum chambers, therefore need to use a kind of device that is referred to as magnetic force transmission mechanism.The common magnetic force transfer device of magnetic force is the earliest because inner structure is unreasonable, move forward and backward with rotary course in be mechanical friction motion completely in pure iron core in vacuum lamp and vacuum lamp inwall, vacuum system is caused to certain pollution, its service life is limited.Magnetic force transfer device described in patent ZL90226957.7 has carried out some improvement at the two ends of pure iron core, it is mainly the roller mode that adopts when axial motion, but is still that roller side and vacuum lamp inwall carry out mechanical friction motion completely when doing radial rotary motion.Because vacuum lamp is inner, be difficult for processing and cause after the not high and baking of inner surface accuracy the reasons such as distortion, transmit and rotary course in exist mechanical friction to cause Caton phenomenon, have a strong impact on the alignment precision to transmission sample in transmittance process.
Summary of the invention
The object of the invention is: propose a kind of magnetic force transfer device that all can flexible motion almost there is no friction in transmission lever direction and radial rotary direction.
The present invention is achieved in that
A kind of magnetic force transfer device, comprise transmission vacuum lamp, and be arranged on the pure iron core slide assemblies transmitting in vacuum lamp, 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 anchor shaft, on described rolling wheel support, along the axial direction that transmits vacuum lamp, be provided with axis hole, anchor shaft stretches in the axis hole of rolling wheel support, its special character is: between the axis hole of described rolling wheel support and anchor shaft, be provided with ball bearing of main shaft, the outer shroud of ball bearing of main shaft is fixedly connected with the axis hole of rolling wheel support, the interior ring of ball bearing of main shaft and anchor shaft flush fit.
Above-mentioned pure iron core is provided with groove along the central axial direction of transmitting vacuum lamp.
Above-mentioned ball bearing of main shaft is enclosed ball bearing of main shaft.
The quantity of above-mentioned groove is 6.
Above-mentioned rollers support is four rolling wheel supports.
The mode that the outer shroud of above-mentioned ball bearing of main shaft adopts pin and pin hole to match with the mode that is fixedly connected with between rolling wheel support.
Advantage of the present invention is:
(1) magnetic force transfer device of the present invention adopts the mode of roller when transmission lever is carried out axial motion, when rotating, also adopt bearing mode, almost there is no mechanical friction, therefore, the operation when transmission sample carries out contraposition of this magnetic force transfer device is more flexible, aligning accuracy improves greatly, has extended the service life of magnetic force transfer device simultaneously.
(2) pure iron core is provided with groove along axis direction, and the torsion that pure iron core is subject to is larger.
