Because precision equipment has higher running speed and production efficiency usually, characteristics such as that the levelling device that therefore requires to match has is simple in structure, compact size, reliable and stable, handled easily.China utility model patent CN200920229790.5 provide a kind of supporting and regulating device, utilizes screw thread pair to realize the support and the height control of weight equipment, the difficult plane adjustment that is used for precision equipment.Other has a kind of levelling gear that adopts flexible hinge, is that the principle that produces the linear elasticity distortion after utilizing flexible hinge in its elastic limit, to be stressed realizes leveling.This mechanism is because the elastic deformation amount of flexible hinge is less, and difficulty reaches big adjustment amount and severe duty requirement.
Summary of the invention
The object of the present invention is to provide a kind of levelness of precision equipment parts or miniature precision levelling device of depth of parallelism adjustment of being used for; This device can be accomplished the parts leveling under the severe duty fast; Be equally applicable to the leveling under the asymmetric situation of load, and apparatus structure is simple, small and exquisite; Easy to adjust flexible, can use in groups so that the leveling on big plane.
A kind of miniature precision levelling device; Comprise support platform, it is characterized in that support platform thread connection homophony is put in order screw rod; End, homophony whole screw rod upper end is stretched out and is connected ball hinged support near the support platform upper surface; The support platform lower surface bevel gear wheel that is threaded is stretched out in the whole screw rod lower end of homophony, bevel gear wheel and bevel pinion interlock mutually, and the sidepiece of bevel pinion is through driving shaft connection handwheel; The bottom of bevel gear wheel connects spring pretension assembly, the main latch assembly of the secondary connection of the whole screw rod lower end of homophony end thread.
Said spring pretension assembly comprises spring base, holddown spring and stage clip packing ring; Spring base one end connects the bottom of bevel gear wheel; The other end connects the top of holddown spring, and the bottom of holddown spring connects the stage clip packing ring, and stage clip packing ring thread connection is fixed on the whole screw rod of homophony.
Said bevel gear wheel adopts the inverse manner whole screw rod of homophony that is threaded near the support platform lower surface.
Said main latch assembly comprises clamping screw and latch segment, the latch segment whole screw rod of the homophony bottom that is threaded, the secondary clamping screw that connects of latch segment side thread.
Said handwheel is provided with the homonymy that homophony is put in order screw rod with main said clamping screw.
Technique effect of the present invention is embodied in:
A kind of precise leveling device of the present invention provides driving force through the adjustment handwheel, drives the whole screw rod rotation of homophony via the transmission of slowdown type bevel gear pair, because effect is dwindled in the displacement of reduction gearing, makes handwheel can accurately adjust the displacement of the whole screw rod of homophony; And the sphere self-adaptive component is installed in order to the adjustment angle of pitch and deflection angle at the whole screw rod end of homophony; After adjustment finished, the latch segment locking homophony of main latch assembly was put in order screw rod, kept the leveling achievement; As optimization, the inversion mounting means that the bevel gear wheel in the paired bevel gear of reduction gear ratio adopts the holddown spring preload pressure to support, the precompression of holddown spring has the precompressed anti-loosing effect to the whole thread connection pair of homophony; Simultaneously, the bevel gear wheel upside down also makes the main body of whole levelling device near supporting component, makes whole apparatus structure compact, small and exquisite; Main latch assembly adopts the form of clamping screw and latch segment, and the clamping screw operating side is arranged on the device homonymy with driving handwheel, and handled easily is saved the space.
