Abstract
The present invention relates to a permanent-magnet driving T-type guide slot sample control and seed crystal applying mechanism used for operating a metal sample in the process of suspension container-free treatment in a vacuum chamber. An internal magnet and an external magnet respectively rotate on an internal magnet supporting cylinder and an external magnet supporting cylinder and are positioned between a screw rod and a handle which are connected with a screw nut with a T-type slot. During operation, the handle is turned, and the screw rod can axially move along the T-type slot under the action of magnetic force and then rotate, or contrariwise, so the present invention can implement seed crystal induction for the sample in the process of suspension container-free treatment and control a freezing process.
Description
The present invention relates in vacuum chamber, suspend test button that no container handles and it is applied the transmission rig of outside seed crystal of a kind of manipulation.
It is the important technology of virtual space material preparation process in ground environment that the suspension of metallic substance does not have the container processing.How to handle the material sample that freely suspends in a vacuum and to control its process of setting be one of key problem in technology of realizing this technological process by applying seed crystal.At present, both at home and abroad prior art one is the simple and easy control stick that is connected with vacuum chamber in the dynamic seal mode, the 2nd, and the corrugated tube transmission or the magnetic driving mechanism that are connected with vacuum chamber in the static seal mode.The former shortcoming is not to be suitable for ultra-high vacuum system, and the latter's deficiency is that structure and operation are comparatively complicated.
The purpose of this invention is to provide a kind of with the static seal mode be connected with vacuum chamber, structure and easy and simple to handle, and can multi-faceted motion transmitting large torque and the operating mechanism of axial force.
Technical solution of the present invention is, inside and outside two-layer magnet is set between handle and screw mandrel, the inside and outside magnet of putting is respectively six, and be bumped into respectively on the inside and outside carrying cylinder, the upper end of screw mandrel and inner support tube join, and its lower end screws in and has in the nut of Г type groove, and Г type groove is by a pilot pin restriction that is fixed on the abutment sleeve, when the turn handle, screw mandrel is done magnetictransmission under the effect of magnet, and movement locus axially moves for moving axially earlier to rotate or rotate earlier again.
Advantage of the present invention is, because the setting of magnet and T type guide slot makes manipulation of the present invention very easy, as long as the turn handle, screw mandrel will rotate and drive nut reposefully and axially move and the angle translation under the effect of magnetic force.Compact construction of the present invention and simple simultaneously can transmitting large torque and axial force.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a Г type groove nut structure synoptic diagram of the present invention.
Chief component of the present invention comprises: bearing sleeve 1, built-in permanent magnet 2, inner support tube 3, external permanent magnet 4, external support tube 5, handle 6, screw mandrel 7, nut 8, pilot pin 9, abutment sleeve 10, handle steady brace 11, union lever 12, quartzy support tube 13, seed crystal 14 and three bearings 15,16,17.
Built-in permanent magnet 2 is connected with the inset type stationary fit with inner support tube 3, and external permanent magnet 4 also is connected with the inset type stationary fit with external support tube 5.All permanent magnets all radially magnetize, and it is N-S-N-S-N-S in proper order that polar contribution is installed.Adopt stationary fit between handle and the external magnetic body support sleeve 5; Bearing sleeve 5 and stainless steel bearing sleeve 1 to be linking to each other movingly, by steady brace 11 both relative movement is restricted to rotation; One end of steady brace 11 and external support sleeve 5 link to each other with screw thread, and the other end stretches into annular guide channel on the bearing sleeve 1 guaranteeing when the turn handle 6, and handle 6 and external permanent magnet 4 and external support tube 5 can smooth rotation and can not move up and down; Interior magnet carrying cylinder 3 links to each other with stationary fit with the top of screw mandrel, the top of abutment sleeve 10 is placed one and is compressed bearing 15, the upper end of bearing sleeve 1 is provided with bearing 16,17, and the abutment sleeve 10 that is screwed on bearing sleeve 1 is restricted to and can only rotates by compressing bearing 15,16,17 motions with screw mandrel 7; Nut 8 and the screw mandrel 7 of band T type guide slot 18 are for being connected movingly, and transmission pilot pin 9 usefulness screw threads are fixed on the abutment sleeve 10, and the other end slides in T type guide slot, thereby make the nut 8 can 0 °≤θ of mobile vertically earlier rotation afterwards ∠ 360 °.One end of union lever 12 and nut 8 are to be threaded, and the other end connects seed crystal 14 again by quartzy support tube 13.
When handling this mechanism, only need turning handle 6, powerful magnetic force will order about screw mandrel 7 and rotate reposefully between the permanent magnet, the running orbit that drives nut 8 owing to the qualification of pilot pin 9 is the Г type, that is: turn an angle after moving a certain distance vertically earlier, 6 nuts 8 of counter-rotating handle can reverse earlier and move vertically in the other direction behind the certain angle again again.
The inside and outside permanent magnet of putting all selects for use the well behaved neodymium iron boron of magnetic substance as magneticsubstance, to guarantee powerful magnetic force between magnet, realizes magnetictransmission, makes simultaneously to transmit moment of torsion and axial force increase.
