Description
Technical field
It is specifically a kind of angle limit mechanism more than 360 degree the utility model is related to switch /V technical field.
Background technology
Angle limit mechanism is to drive the synchronous rotation of output by synchronous belt by being driven input synchronizing wheel currently on the market
Dynamic transmission mechanism, the common synchronizing wheel transmission of such transmission mechanism；But due to synchronous belt, there are certain biographies with synchronizing wheel
Dynamic error causes transmission accuracy that can not meet our requirement, therefore we are needed to synchronous belt and synchronizing wheel into line position
Compensation is put, synchronizing wheel and the error of synchronous belt are reduced to minimum purpose by way of compensation；But transmission mechanism because
Synchronous belt, which rotates a circle synchronizing wheel, needs 6 circle of rotation more, and is that no turnning circle limits, therefore passes through electrical origin sense
The mode back to zero of answering can not ensure that the tooth that synchronous belt is contacted with synchronizing wheel during origin position is a similary position, if can not ensure
Synchronous belt and synchronizing wheel are same positions during origin position, then synchronous belt is just unable to reach with synchronizing wheel error compensation mode
Reduce driving error as a result, therefore transmission accuracy is unable to reach requirement.

Inductor B is symmetricly set on the both sides of angle limit bottom plate.
As further program of the utility model：The inductor A and inductor B is electrically connected by conducting wire with host computer
It connects.
As the utility model further scheme：The angle limit bottom plate is integrally formed using flame-proof PVC material
It is fabricated.
Compared with prior art, the beneficial effects of the utility model are：The utility model increases mechanical angle limitation, prevents
Mechanism can rotate multi-turn like that before occurring causes synchronous belt and synchronizing wheel different to cause in the when tooth that contacts of same origin
Angle position deviation has used the mode of mechanical slip /V to increase the angle of mechanical position limitation, is limited by fixed pin and angle
Position bottom plate carrys out the angle of limit slippage；Increase another angle sensing chip 2 and inductor 2 detect current angular whether
Near 360 °, if angle sensing chip 2 trigger inductor 2 illustrate current angular be near 360 degree, it is attached at 0 ° under normal circumstances
If triggered origin during nearly Aligning control, origin signal is axially moved apart to pros, then toward negative direction origin is being looked for return
Zero, if not triggering origin signal, origin back to zero directly is looked for toward negative direction, during so as to avoid corner close to 360 or so, electrically
Origin switch position has with 360 or so at 0 ° and triggers electrical origin signal simultaneously；If (the positive direction in 360 ° of neighbouring positions
Cross origin and triggering origin), it is required for first leaving origin signal position toward negative direction movement, then restarts back to zero function, i.e.,
Negative direction looks for origin signal back to zero, and synchronous belt and synchronizing wheel are in the range of effective travel when so ensuring that each Aligning control
The position of the tooth of contact is same fragment position, then the error of synchronous belt and synchronizing wheel can be compensated by software.
Reach the function of improving corner accuracy.
