Abstract
The utility model discloses a kind of mechanical structure of quick locking of setting a table for two degrees of freedom.Be made up of blade seat, vane group, loose collar, torsion spring, loose collar, trim ring, unlock switch, spring, bearing pin, the first vane pin, the second vane pin.This fast locking mechanism is easy and simple to handle, quick, reliability is high.The mechanical structure of quick locking, by the dynamic three groups of blade rotaries of rotary moveable endless belt, is gathered to center, is realized locking function; The lock function after locking is realized by unlock switch; When after the lock function untiing unlock switch, in blade seat, torsion spring drives loose collar to rotate backward, and then controls three groups of blade counterrotatings, realizes unlocking.
Description
Technical field
The utility model belongs to mechanical structure field, is specifically related to a kind of two degrees of freedom and sets a table quick-locking mechanism.
Background technique
Two degrees of freedom is set a table and to be made up of inner ring, outer shroud, coupling shaft etc.The inner ring that two degrees of freedom is set a table, in limited angle, azimuth direction and pitch orientation can be rotated arbitrarily.It is the main composition structure forming the equipment such as stabilized platform, rocking vibration platform and instrument that two degrees of freedom is set a table, and in working order, two degrees of freedom is set a table and can be rotated arbitrarily, but in off working state, fixing, locking of two degrees of freedom need being set a table, limits it and freely rotate.Usual way on the turning axle of inner ring and outer shroud, increases locking mechanism respectively, locks respectively.
The shortcoming of said method needs to carry out two step behaviour to do, and complex operation, operating process is slow, can not realize quick locking.
Model utility content
For the above-mentioned technical problem existed in prior art, the utility model provides a kind of two degrees of freedom and to set a table quick-locking mechanism, comprise blade seat, vane group, loose collar, torsion spring, trim ring, unlock switch, spring, bearing pin, the first vane pin, the second vane pin, described vane group, loose collar, torsion spring, trim ring, spring, unlock switch are installed in blade seat, described vane group has three groups, is connected with blade seat by the first vane pin; Described loose collar is arranged on the outside of vane group; Described torsion spring is arranged on the outside of loose collar; Described trim ring is arranged on the outside of torsion spring, and is connected with blade seat by screw thread; Described unlock switch is connected with blade seat by bearing pin, and pressing spring.
Further, described vane group is rotated around the first vane pin.
Further, described loose collar is provided with driving lever.
Further, be provided with groove in described loose collar, when loose collar rotates, the groove in loose collar drives the second vane pin to control vane group and rotates around the first vane pin.
Two degrees of freedom of the present utility model is set a table, and quick-locking mechanism is easy and simple to handle, quick, reliability is high.The mechanical structure of quick locking, by the dynamic three groups of blade rotaries of rotary moveable endless belt, is gathered to center, is realized locking function; The lock function after locking is realized by unlock switch; When after the lock function untiing unlock switch, in blade seat, torsion spring drives loose collar to rotate backward, and then controls three groups of blade counterrotatings, realizes unlocking.

Wherein each reference character implication: 1-locking mechanism, 2-pedestal, 3-inner ring, 4-outer shroud, 5-trim ring, 6-torsion spring, 7-loose collar, 8-vane group, 9-bearing pin, 10-spring, 11-unlock switch, 12-blade seat, 13-first vane pin, 14-second vane pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-5, two degrees of freedom of the present utility model quick-locking mechanism of setting a table comprises blade seat 12, vane group 8, loose collar 7, torsion spring 6, trim ring 5, unlock switch 11, spring 10, bearing pin 9, first vane pin 13, second vane pin 14, vane group 8 is installed in blade seat 12, be connected with blade seat 12 by the first vane pin 13, have 3 groups; Loose collar 7 is installed in blade seat 12, in the outside of vane group 8; Torsion spring 6 is installed in blade seat 12, in the outside of loose collar 7; Trim ring 5 is installed in blade seat 12, in the outside of torsion spring 6, is connected with blade seat 12 by screw thread; Spring 10 is installed in blade seat 12, and unlock switch 11 is installed in blade seat 12 and is connected with 9 blade seats 12 by bearing pin 9, and pressing spring 10.
Three groups of vane group 8 are installed in blade seat 12, can rotate around the first vane pin 13, loose collar 7 is installed in blade seat 12, the rotation of loose collar 7 is controlled by the driving lever on loose collar 7, fluted in loose collar 7, when loose collar 7 rotates, drive the second vane pin 14 motion to control vane group 8 by the groove in loose collar 7 and rotate around the first vane pin 13.
Two degrees of freedom of the present utility model set a table quick-locking mechanism use time, when loose collar 7 rotates counterclockwise, three groups of vane group are stretched out and are gathered to center from blade seat 12, clamp the axostylus axostyle that inner ring 3 is stretched out, realize locking function, simultaneously, the driving lever of loose collar 7 is unlocked switch 11 and pins, prevent loose collar 7 from turning round, vane group 8 loosens, and then ensures reliability and the soundness of locking.When needs unlock, press unlock switch 11, the driving lever of loose collar discharges by unlock switch 11, and in blade seat, the outside of loose collar is provided with torsion spring 6, drives loose collar 7 to rotate clockwise, groove bands moving vane group 8 in loose collar 7 is disperseed to surrounding, return in blade seat 12, realize quick release, due to the effect of the power of torsion spring 6, when not having external force to stir the driving lever of loose collar 7, vane group 8 can not be gathered to center.What lock due to locking mechanism 1 is projecting shaft in inner ring, so, once locking, just can lock the rotation of inner ring in pitch orientation and azimuth direction both direction, realize quick locking.
