Exactness is not high, causes signal detection to be forbidden.
Utility model content
The utility model aims to provide a kind of track traffic for avoiding encoder inclined main axes, improving signal detection precision and used
High precision photoelectric encoder.
A kind of track traffic high precision photoelectric encoder described in the utility model, including ring flange, and be arranged on
Main base on ring flange, through hole is provided with the main base, the top and bottom of through hole are respectively arranged with deep-groove ball
Bearing, encoder main shaft pass vertically through two deep groove ball bearings up and down, the encoder master below the deep groove ball bearing of the lower end
Jump-ring slot is provided with axle, is provided with the jump ring of deep groove ball bearing locking positioning, the deep-groove ball axle of the upper end in jump-ring slot
Hold and external screw thread is provided with the encoder main shaft side wall of top, locking nut, which is screwed on encoder main shaft, locks deep groove ball bearing
Tightly, the encoder main shaft top is also arranged with code-disc, and the one being connected on main base is additionally provided with above the code-disc
Change photoimpact processing module, the connecting cylinder side wall of the code-disc is pushed against on encoder main shaft by grub screw, by code-disc
It is fastened as a whole with encoder main shaft.
A kind of track traffic high precision photoelectric encoder described in the utility model, because encoder main shaft uses up and down
Two deep groove ball bearings support jointly, make encoder main shaft when with drive mechanism high-speed rotation will not run-off the straight, make rotation
It is more steady, when avoiding the high speed rotation of encoder main shaft the problem of sideslip, also extend the service life of encoder main shaft, drop
The low replacement cost of encoder；Due to carrying out signal-obtaining conversion using integrated optical Electric Pulse Treatment module, circuit is realized
The plate structure integrated with read head, make transmitter module and receiving module integration, so as to simplify mounting structure, reduce to peace
The requirement of precision is filled, improves accuracy of detection, moreover it is possible to the axiality requirement to code-disc is reduced, because code-disc directly passes through grub screw
It is fixed on encoder main shaft, it is ensured that measurement input coding device main shaft leads the axiality of measurement end, is compiled so as to improve
The measurement accuracy of code device, in addition, held out against using grub screw, because face contact is better than the arc surface of common jackscrew point engagement shaft,
Therefore, increase contact area, locking effect is more preferable, and is locked by grub screw, also allows for subsequently changing code-disc, and dismounting is just
Profit.
