Description

The universal balance compass of more piece bearing mechanism

Technical field:

The utility model relates to the self-adjusting mechanism of a kind of verticality, particularly a kind of mechanism of vertical hanging sophisticated sensor.

Background technology:

Existing typical compass mechanism is two joint adjustment structures, the sensor that is usually used in the vertical hanging precision, or be used for the vertical hanging parts the strict vertical occasion that requires need be arranged, typical case's compass mechanism as shown in Figure 9, this mechanism includes outer shroud 91, outer coupling shaft 92, compositions such as interior ring 93 and interior coupling shaft 94, wherein outer shroud 91 can rotate around being arranged on the outer coupling shaft 92 that compass puts on the shelf, but the interior coupling shaft 94 that 93 windings of interior ring are put at outer shroud 91 rotates, thereby the parts (as sensor etc.) that need to keep accurate verticality in guaranteeing to be installed on the ring 93 can be done 360 ° around the center line of structure and rotate freely motion, when the external structure part tilts, need to keep the parts of accurate verticality can automatically restore to plumbness, mechanism is used for vector sensor as compass, the direction of measurement that can make vector sensor all the time vertically downward, above-mentioned typical compass mechanism is in order to guarantee the verticality of installing component, in the requirement, the outer shroud process and assemble need have higher symmetry, require each member dead weight in the mechanism little simultaneously, each coupling shaft not only size is little, the friction of its supporting also should be as far as possible little, but still there is following point in existing typical compass mechanism:

1. existing typical compass mechanism is 2 joint adjustment structures (being outer shroud 91 and interior ring 93), and it is relatively poor that it regulates degree of freedom, and when the structure degree of tilt was big, compass mechanism was owing to the restriction of self structure loses the verticality regulating power, or appearance " stuck " phenomenon;

2. sliding bearing is all adopted in the supporting of the inside and

outside coupling shaft

92,94 of existing typical compass mechanism, its sliding friction damping is bigger, influence the verticality regulatory function of mechanism, it is big simultaneously respectively to support span, the symmetry difficulty that realizes himself structure is bigger, and its symmetric difference bring big negative effect can further for mechanism's verticality regulating effect.

3. after using for a long time in the mechanism, or after using under the environment of vibration, its yielding structure and its sliding bearing easy to wear, its self-poise performance descends, cause the mounted component verticality can not satisfy the requirement of regulation, thereby need mechanism is carried out regular maintenance or changes member, serviceable life is short, the use cost height;

4. existing compass mechanism resistance to shock is poor, because essential glade plane space between each supporting surface of contact causes the instability in the structure use.

The utility model content:

Technical problem to be solved in the utility model provides the universal balance compass of a kind of more piece bearing mechanism, and it can have strong degree of freedom regulating power for mechanism, and can improve the verticality regulating effect, and structural stability is strong, and maintainability is good, long service life.

The technical scheme in the invention for solving the above technical problem is:

The universal balance compass of more piece bearing mechanism, the upper end of this mechanism is connected with structural member, the lower end of this mechanism is connected with the parts of strict demand are vertically arranged, be characterized in: described compass mechanism has compass frame on, should go up the compass frame is hinged with Y-piece through first articulated elements of hinge assembly a end, the other end of this Y-piece is hinged with rod like parts one end through second articulated elements of hinge assembly, the other end of this rod like parts is hinged with down the compass frame through the 3rd articulated elements of hinge assembly, the first articulated elements axis of described hinge assembly is vertical mutually with the second articulated elements axis, its second articulated elements axis is vertical mutually with the 3rd articulated elements axis, constitutes the universal balanced structure of more piece bearing.

The utility model adopts the more piece adjustment structure, compare with tradition 2 joint adjustment structures, the adjusting degree of freedom is better, can eliminate mechanism's " stuck " phenomenon, the utility model adopts hinge assembly to be rolling bearing, frictional damping is little, its upper and lower compass frame, Y-piece and rod supporting span is little and symmetry good, can further improve the verticality regulating effect of mechanism, simultaneously because hinged each member wearing and tearing are little, the rigidity of structure is big, can prolong mechanism serviceable life, reduce mechanism's use cost, and can improve the antivibration ability and the stability of mechanism.
