【Technical field】
The technical field of automation equipment is the utility model is related to, more particularly to a kind of angular surveying for rotary shaft fills
Put.
【Background technology】
In automation equipment, it is sometimes desirable to measure the anglec of rotation of rotary shaft, the judgement for its stop position.It is existing
Angle measurement unit be by angular encoder directly with rotate axis connection, must assure that the output of angular encoder when mounted
End and rotary shaft are concentric, and installation requirement is high, slightly loosen or eccentric, angular encoder easily damages.Further, angular encoder
Output end lack guiding, the vibration of lathe drives angular encoder vibration, and measurement accuracy is low.
【Utility model content】
In view of this, it is overcome the deficiencies in the prior art, the utility model provides a kind of angular surveying for rotary shaft
Device, by the improvement of structure, installation requirement is reduced, extend the service life of angular encoder, accuracy of detection is high.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of angle measurement unit for rotary shaft, including angular encoder, one end of the angular encoder are set
There is encoder support, the encoder pedestal upper end is internally provided with rolling bearing, and the inside of the rolling bearing is cased with connecting
Spindle, the connecting shaft runs through the encoder support, and the output end of the angular encoder is placed on described connecting shaft one end
Inside, the other end of the connecting shaft is cased with flexible clutch, and the other end of the flexible clutch is connected with rotary shaft.Institute
State rolling bearing and connecting shaft is used for the guiding of the angular encoder output end, smooth running, using reliable；The flexibility
The setting of shaft coupling reduces installation requirement, avoids angular encoder from being damaged by the effect of side force.
Preferably, the side of the connecting shaft is provided with lock-screw, one end of the lock-screw is mutually butted on the angle
The output end of encoder is spent, the connection that the lock-screw is used for the connecting shaft and the angular encoder output end fastens,
It is easy to use.
Further, the encoder support is in inverted T font, and the both sides of the encoder pedestal lower end are used to install spiral shell
Nail, uniform force, connection fastening.
The beneficial effects of the utility model are：(1) by the setting of flexible clutch, the installation of angular encoder is reduced
It is required that it is easy to use, reliable, extend service life；(2) rolling bearing and connecting shaft is set to be used for the angular encoder
The guiding of output end, make the angular encoder smooth running, improve measurement accuracy.
【Brief description of the drawings】

【Embodiment】
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Reference picture 1, a kind of angle measurement unit for rotary shaft, including angular encoder 3, the angular encoder 3
One end be provided with encoder support 1, the upper end of encoder support 1 is internally provided with rolling bearing 5, the rolling bearing
5 inside is cased with connecting shaft 6, and the connecting shaft 6 runs through the encoder support 1, and the output end set of the angular encoder 3
In the inside of described one end of connecting shaft 6, the other end of the connecting shaft 6 is cased with flexible clutch 7, the flexible clutch 7
The other end is connected with rotary shaft 9.The rolling bearing 5 and connecting shaft 6 are used for the guiding of the output end of angular encoder 3,
Smooth running, using reliable；The setting of the flexible clutch 7 reduces installation requirement, avoids angular encoder 3 by side
Damaged to the effect of power.
The side of the connecting shaft 6 is provided with lock-screw 8, and one end of the lock-screw 8 is mutually butted on the angle and compiled
The output end of code device 3, the connection that the lock-screw 8 is used for the connecting shaft 6 and the output end of angular encoder 3 fasten,
It is easy to use.
The encoder support 1 is in inverted T font, and the both sides of the lower end of encoder support 1 are used for mounting screw, and stress is equal
It is even, connection fastening.
Before use, rolling bearing 5 to be installed on to the inside of the upper end of encoder support 1, and fixed with jump ring 4, avoid rolling
Bearing 5 comes off；Connecting shaft 6 is placed on to the outside of the output end of angular encoder 3, and locked with lock-screw 8；Again by angular coding
Device 3 and connecting shaft 6 insert the inside of rolling bearing 5, and angular encoder 3 is installed on encoder support 1 with screw 2；
