The mechanism disclosed by the utility model concurrently has locking and automatic unlocking functions of rotating mechanical limitation of rotating tables; the mechanism is simple and reliable and is designed in an integrated way; the locking only limits the rotating degrees of freedom; and the mechanism has no external force on a precision rotating shaft system.
Description
Technical field
The utility model relates to a kind of positioning and locking and release mechanism of rotating machinery.
Background technology
At present, the locking of the rotary freedom of photoelectric measurement equipment all is to realize by lock-screw or screw rod, manually finishes locking and unlocking operation by the people.Along with the widespread adoption of two-dimensional tracking turntable at aerospace field, be difficult to even can't have opened by the manual operation of people the rotary freedom of turntable.Before mounting platform does not enter duty; if the rotary freedom of turntable is not locked; the optical device that turntable carries can cause damage because of vibration and impact, therefore the rotary freedom of turntable must be locked, thus the optical device that protection is carried.After platform to be installed entered duty, the rotary freedom that recovers again turntable made it in running order.Present existing locking mode adopts motor to power up locking, and its locking torque is little, is only applicable to the application of little load, and need to give power devices before mounting platform does not enter duty, has limited the popularization of this locking mode.
The utility model content
For solve existing locking mode locking torque little, the technical matterss such as supplemental support rigidity can't be provided, the utility model provides a kind of two-dimensional tracking turntable locking and automatic unlocking mechanism, adopt a kind of blasting bolt priming system locking mode, take into account the spacing locking of turntable rotating machinery and automatic unlocking, simple and reliable.
It is as follows that the utility model solves the problems of the technologies described above the basic technical scheme of employing:
A kind of two-dimensional tracking turntable locking and automatic unlocking mechanism, in order to locking and release tumbler, it is characterized in that: this locking and automatic unlocking mechanism comprise hold-down support, blasting bolt, set nut and in order to sending the microswitch component of blasting bolt status signal, and described microswitch component comprises the microswitch mount pad on the axle that is socketed in blasting bolt and is installed on microswitch on the microswitch mount pad; Be connected in series screw thread by blasting bolt between tumbler and the hold-down support and fix, hold-down support and microswitch mount pad lay respectively at the both sides of tumbler, and set nut is locked together microswitch mount pad, tumbler and hold-down support.
Based on above technical scheme, the utility model has also further been done following optimization and has been improved.
In the outside of blasting bolt, also be provided with in order to collect the recycling box of blasting bolt separating head and tumbler when the release.
On the blasting bolt, the rear portion of set nut is fixed with buffering ring by screw thread, and this buffering ring can reduce the blasting bolt separating head to the impulsive force of recycling box bottom surface by plastic yield when release.
The utlity model has following advantage:
1, integrated design, simple and reliable for structure.Locking only limits rotary freedom, does not have external force additional to precise rotation axle system.This locking release mechanism reliability is high, locking release feedback signal is arranged, overflow without fifth wheel, can play the effect of mechanical position limitation simultaneously in turntable, and what meet aerospace applications simple and reliablely waits requirement.
2, the utility model adopts the blasting bolt priming system, hold-down support is connected by blasting bolt with tumbler, the microswitch that adds reflection locking or released state, can realize automatic operation, and have larger bending resistance and tensile strength, be particularly suitable for existing than under big bang and the impact condition to restriction and the release of rotary freedom.
3, the utility model can realize successfully that the two-dimensional tracking turntable is than big bang and the mechanism that impacts condition its rotary freedom of lower limit system and play the effect of supplemental support, can realize automatic unlocking according to steering order.
4, by being set, buffering ring guaranteed the non-pollution safety reliable recovery of blasting bolt separating head.

Embodiment
The utility model is mainly used in the locking of two-dimensional tracking turntable under off working state, can realize automatic unlocking according to instruction, and is in running order after the release.Below in conjunction with accompanying drawing this mechanism and use thereof are carried out the example explanation.
Referring to Fig. 1, hold-down support and reference for installation are connected, and are used for fixing the effect that blasting bolt plays the turntable mechanical position limitation simultaneously; Blasting bolt is the main stressed member of mechanism, bears because turning moment and the moment of flexure of generation of vibration; By the microswitch mount pad microswitch is depressed generation locking signal (showing current locking state) when set nut internal thread and blasting bolt are connected, its external thread and buffering ring are connected.
Connect by the blasting bolt priming system between tumbler and the hold-down support, in the time of the locking nut screwing priming system microswitch depressed and provide the locking state signal, then buffering ring is fixed on the set nut by screw thread, recycling box is fixed by screws on the tumbler.Buffering ring is made by the thin-walled brass material, when priming system powers up separation, prolong the blasting bolt separating head to the action time of recycling box bottom surface by its plastic yield, play the effect that reduces impulsive force, guarantee the free of contamination safe retrieving of separating head, microswitch is upspring and is produced unlocking signal (showing current released state) simultaneously.
During locking, rotation tumbler 3 makes itself and hold-down support 2 end contacts, blasting bolt 1 is connected with hold-down support 2 by the screw thread on it, the microswitch mount pad 4 that microswitch 8 is housed is enclosed within on the axle of blasting bolt 1, thereby set nut 5 is connected by screw thread and blasting bolt 1 hold-down support 2 and tumbler 3 is locked together, and has limited the rotary freedom of tumbler.Again buffering ring 6 is connected by the screw thread on it and set nut 5, at last recycling box 7 is fixed by screws on the tumbler 3, play the effect of reclaiming the blasting bolt separating head.
After receiving unlock command, blasting bolt is by inner electric initiator explosive blasting, by the chemical energy of explosive the A face of blasting bolt from Fig. 1 is divided into two parts, realized the release of rotary freedom.
