Description
Technical field
The utility model belongs to vacuum equipment field, specifically a kind of automatically controlled differential extraction vacuum rotating platform.
Background technique
Vacuum technique is preparation and the key technology of testing new material, virtual space experimental situation.In vacuum environment, often need rotary sample even to rotate a whole set of heavy load vacuum system, will ensure to destroy vacuum environment simultaneously.Rotating platform is generally arranged between vacuum environment and air, and rotating part is in vacuum environment, and rotating platform becomes the position of vacuum leak, easily causes vacuum environment to be destroyed.
Model utility content
The utility model provides a kind of automatically controlled differential extraction vacuum rotating platform, in order to solve defect of the prior art.
The utility model is achieved by the following technical programs:
Automatically controlled differential extraction vacuum rotating platform, comprise base, base arranges rotary seat, between rotary seat and base, bearing is set, bearing is made up of bearing inner race and bearing outer ring, forms cavity between bearing inner race and bearing outer ring, and base offers gas port, gas port one end connects cavity, and the other end of gas port connects extraction pump; Rotary seat side arranges worm gear, and the side of worm gear is equipped with worm screw, and one end of worm screw connects motor; Between rotary seat and base, sealing rubber ring is set.
Automatically controlled differential extraction vacuum rotating platform as above, described sealing rubber ring is made up of interior sealing rubber ring and external sealed rubber ring, and the end of gas port is between interior sealing rubber ring and external sealed rubber ring.
The utility model has the advantages that: the bearing inner race of the utility model rotating platform and bearing is arranged in vacuum environment, is sealed by sealing rubber ring, constantly carry out in using process extraction pump vacuumizing process, the degree of vacuum in vacuum environment can be kept.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model perspective view; Fig. 2 is plan structure schematic diagram of the present utility model; Fig. 3 is main TV structure schematic diagram of the present utility model.
Reference character: sealing rubber ring 11 external sealed rubber ring in 1 motor 2 worm screw 3 worm gear 4 rotary seat 5 extraction pump 6 bearing outer ring 7 base 8 bearing inner race 9 gas port 10.
Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Automatically controlled differential extraction vacuum rotating platform, as shown in Fig. 1, figure and Fig. 3, comprise base 7, base 7 is arranged rotary seat 4, arrange bearing between rotary seat 4 and base 7, bearing is made up of bearing inner race 8 and bearing outer ring 6, cavity is formed between bearing inner race 8 and bearing outer ring 6, base 7 is offered gas port 9, gas port 9 one end connects cavity, and the other end of gas port 9 connects extraction pump 5; Rotary seat 4 side arranges worm gear 3, and the side of worm gear 3 is equipped with worm screw 2, and one end of worm screw 2 connects motor 1; Between rotary seat 4 and base 7, sealing rubber ring is set.Motor 1 drives worm screw 2 to rotate, and worm screw 2 coordinates with the worm gear 3 of rotary seat 4, and driven rotary seat 4 rotates.Constantly carry out in extraction pump 5 in rotary course vacuumizing process, the degree of vacuum in vacuum environment can be kept.
Specifically, described sealing rubber ring is made up of interior sealing rubber ring 10 and external sealed rubber ring 11, and the end of gas port 9 is between interior sealing rubber ring 10 and external sealed rubber ring 11.Sealing rubber ring 10 and external sealed rubber ring 11 in adopting, timely gas leakage also can be taked multi-stage sealed.Extraction pump 5 is got rid of because rotating a small amount of gas introduced, and forms a buffer area between interior sealing rubber ring 10 and external sealed rubber ring 11, maintains the inner high vacuum of the utility model from face.Adopt small step elongation 0.9 degree of motor and little helical pitch 1mm worm screw, running accuracy 0.01 degree can be reached.
The utility model not only to operand in vacuum system, also can carry out precision rotation control to a whole set of heavy load vacuum system.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment's technological scheme of the utility model.
