Technical background
Many automatic turntables of domestic production, automatic rotary framework or automatic rotary measuring instrument etc.
In automatic rotary equipment, either indoor equipment or mobile unit, for internal rotating shaft
Duty is controlled, device interior all need install automatic locking mechanism, test or
Auto lock will be carried out by countershaft, to meet automatization's stream in work process during use
The needs of journey.
The most more common domestic retaining mechanism has the locks such as bolt-type, axle hung type, end tooth disc type
Tight mechanism, the most all there are certain pluses and minuses in this several ways, bolt-type is locked
Spring catch is mainly properly inserted in the locking hole of rotating part by tight mechanism by motor,
This mechanism advantage is reliable lock, and shortcoming is that whole retaining mechanism takes up room greatly, controls
System complex, cost is high.Axle hung type locks the structural principle mainly by brake block to turning
Axle is held tightly, controls opening or locking of brake block by motor pulling force, this mechanism
Advantage be take up room little, it is easy to mounting and adjusting, shortcoming is that whole mechanism locking property is reliable
Property poor, and need periodically locking steel wire rope is adjusted, use push away protect relatively complicated.End tooth
Disc type retaining mechanism mainly a pair high accuracy fluted disc of processing be separately mounted to gyroaxis end face and
The end face of retaining mechanism, utilizes pitch wheel to lock, the advantage of this mechanism
Being that the stability after locking is preferable, reliability is high, and shortcoming is that cost is high, and whole mechanism takies
Axial space size is bigger.
The retaining mechanisms such as conventional bolt-type, axle hung type, end tooth disc type in use go out
Existing main problem is: during short-period used, reliability is higher, re-uses after long-term placement
Or when re-using after there is vibration, impact, high/low temperature, reliability can be substantially reduced.Mainly
Reason is: retaining mechanism is typically chronically at locking state, is just unlocked during work.This
Class mechanism substantially utilizes the screw thread pair in retaining mechanism to move, and relies on machine during locking
Screw thread pair in structure carries out self-locking, owing to the screw thread pair being arranged in retaining mechanism is chronically at
Stress, after a period of time does not works, because of the reason such as the temperature difference, Transport Vibration, in mechanism
Screw thread pair can produce certain elasticity or plastic deformation, need to first overcome this screw thread during unblock
Deformation, so can make initial releasing force increase more, thus cause retaining mechanism unlock can not
The phenomenon leaned on, even cannot use.
Also having the retaining mechanism of a kind of electromagnetic clutch type, it is mainly by electromagnetic clutch
Principle, installs an electromagnetic clutch, by whole electromagnetic clutch between rotating shaft and pedestal
The power on/off of retaining mechanism reaches locking or the purpose unlocked, and the advantage of this mechanism is lock
Tight reliable, simple in construction, taking up room little, shortcoming is the electricity produced during the work of whole mechanism
Magnetic field is relatively big, has bigger electromagnetic interference to equipment, has during to the electronic device works of surrounding
Large effect, the most this retaining mechanism also cannot carry out electromagnetic shielding completely.
Summary of the invention
Present invention aim to provide a kind of rotating shaft automatic locking mechanism, this mechanism is along turning
Axial and radial is locked, environmental suitability is strong, compact conformation, take up room little, locking can
Lean on, the equipment that do not affects normally works.
For realizing this purpose, the rotating shaft automatic locking mechanism designed by the present invention, its feature exists
In: it includes tooth shape cylinder slide block, lock bracket, linear bearing, stop nut, guiding
Stud, ram seat, spring, motor mount, linear electric motors, potentiometer sensing chip, electricity
Position device pressing plate and potentiometer, wherein, described lock bracket bosom position is provided with cylindrical hole,
Described tooth shape cylinder slide block is arranged in cylindrical hole by linear bearing, tooth shape cylinder slide block
Front end is provided with breach, and breach is installed potentiometer sensing chip, the front end face of tooth shape cylinder slide block
Being provided with tooth, the front end of lock bracket, tooth shape cylinder slide block are stretched out in the front end of tooth shape cylinder slide block
Rear end be provided with chute, stop nut is arranged in chute, and the base of described ram seat is fixed
At the rear end face of tooth shape cylinder slide block, it is provided with guide through hole in ram seat, before guiding screw pole
End is threadeded through guide through hole and with stop nut, and the base of ram seat is to stop nut
Carry out spacing；
The housing of described linear electric motors connects by motor mount is fixing with the rear end of lock bracket
Connecing, be provided with coupling hole in motor mount, the power output shaft of linear electric motors is in coupling hole
Fix with the bottom of guiding screw pole and be connected, the power output shaft of linear electric motors and guiding screw pole energy
Moving in coupling hole, one end of spring is connected with the base of ram seat, the other end of spring

The rotating shaft automatic locking mechanism of the present invention is different from the duty of conventional retaining mechanism,
When mechanism is in and locks for a long time, mainly locked by internal spring force, lock
Tight in-house screw thread pair is in free unstressed state.It is in when the retaining mechanism short time
During released state, overcome spring force by motor pulling force, make the profile of tooth on retaining mechanism sliding
Block departs from locking gear, thus realizes unlocking.Owing to unlocked time is shorter, and dimension
Time required for holding unblock is the shortest, and in this time, changes in environmental conditions is little, thus can be big
The big functional reliability improving retaining mechanism.
Contour structures of the present invention is compact, it is little to take up room, low cost, assembling and convenient disassembly,
