Background technique
Vacuum technique is preparation and test new material, the key technology of virtual space experimental situation.In vacuum environment, often needing accurate transmission sample, will ensure to destroy vacuum environment simultaneously, especially when testing magnetic susceptible material, needing to stop external magnetic field interference completely.Therefore necessarily require the operation by air side transmission mechanism, realize controlling vacuum side object highi degree of accuracy, and meet without magnetic requirement.
Existing vacuum conveyor, disclosed in Chinese utility model patent CN201155323Y " ultrahigh vacuum linear importing propulsion device ", comprises edge of a knife flange, bellows, introduction rod, outside catch bar and set screw.By promoting the outside catch bar of atmospheric side, driving the introduction rod in bellows movable, reaching target location hand screwed in place screw.Although introduction rod can in vacuum system free straight line motion, but owing to having lacked the accurate screw rod of stabilization, under external pressure effect, each change position, first must unscrew set screw, then hand firmly helps outside catch bar push-and-pull to target location, and then screwed in place screw, complex operation like this, and screwed in place screw can produce minor shifts instantaneously, is difficult to accurate location.
Another Chinese utility model patent CN201409102Y disclosed " ultrahigh vacuum two-dimensional magnetic combination drive ", comprises outer tube Magnetic handle, interior pipe Magnetic handle, two connecting rods and linear bearing.Closed by magnetic knot, side promotes outer tube Magnetic handle outside, and then pipe Magnetic handle in driving, and then drives two link linears be connected with interior pipe Magnetic handle to move.Because which introducing magnetic field, non-magnetic environment requirement cannot be met.
Model utility content
The utility model provides a kind of highi degree of accuracy vacuum without magnetic transmission mechanism, realizes linear transmission sample operation in vacuum non-magnetic environment, in order to solve defect of the prior art.
The utility model is achieved by the following technical programs:
Highi degree of accuracy vacuum is without magnetic transmission mechanism, comprise edge of a knife flange, bellows and outer sleeve are installed in edge of a knife flange bottom, bellows is in outer sleeve, bellows lower end fixed installation nut, bar in suit in bellows, interior bar middle and lower part is hollow, interior bar lower end is fixedly connected with bellows, coordinate in nut and precision lead screw is installed, accurate lead screw upper end is inserted into interior bar, bearing is installed in the lower end of precision lead screw, the outer ring of bearing connects outer sleeve by jackscrew, the bottom suit handwheel of outer sleeve, the bottom of handwheel arranges handwheel screw, handwheel screw is connected with accurate lead screw through handwheel, handwheel and accurate lead screw can synchronous axial system, outer sleeve sidepiece offers vertical guiding groove, and nut sidepiece installs guide rod, and guide rod coordinates with guiding groove.
Highi degree of accuracy vacuum as above is without magnetic transmission mechanism, and described periphery, handwheel upper end arranges the graduation line of annular, and outer sleeve lower end arranges indicating arrow close to the position of handwheel.
Highi degree of accuracy vacuum as above, without magnetic transmission mechanism, the outer sleeve outside described guiding groove is arranged the graduation line of vertically arrangement.
Highi degree of accuracy vacuum as above is without magnetic transmission mechanism, and the helical pitch of described accurate lead screw is 1mm.
The utility model has the advantages that: the utility model, by rotation hand wheel, drives precision lead screw to rotate, thus drives inner nut, and then drive bellows and interior bar moving linearly.After arriving target location, without the need to other operation, target location can be stabilized in.
