Description
Technical field
The utility model relates to rotary encoder fields, more particularly to a kind of encoder zero-crossing detecting device.
Background technique
Encoder is to work out signal or data, be converted to the signal form that can be used to communication, transimission and storage
Equipment.Encoder needs to carry out zero point detection to it before use, to ensure that its operation turns steady, does not shift.City at present
Zero-crossing detecting device on face uses the instruments such as high-precision sensor, and operation difficulty is big, at high cost.Therefore one kind is needed
Novel encoder zero-crossing detecting device solves problem above.
Utility model content
The purpose of this utility model is to provide a kind of encoder zero-crossing detecting devices, solve existing in the prior art
Zero-crossing detecting device operation difficulty is big, the high problem of use cost.
To achieve the above object, the utility model is achieved through the following technical solutions:
A kind of encoder zero-crossing detecting device, including flange and barrel-type casing are provided with annular detection zone in the shell,
The detection zone is made of conductive metal sheet, and the conductive metal sheet two sides are connect by conducting wire with current measuring instrument, the shell
External wall is provided with convex block, and sliding slot engaged therewith is fixedly connected with the flange, and the convex block and the sliding slot connect
Contacting surface is engaged by screw thread；
Further include shaft coupling detection set, be fixedly installed on shaft coupling, shape is regular polygon.
Preferably, the conductive metal sheet is fixedly connected by screw with the inner walls.
Preferably, the shaft coupling detection set shape is regular hexagon.
Preferably, the flange is fixedly installed on encoder.
The beneficial effects of the utility model, the shaft coupling detection set of the utility model can amplify the operation feelings of shaft coupling
Condition, if the deflection of very little occur in encoder and shaft coupling, the amplification through shaft coupling detection set, deflection embodies brighter
It is aobvious.Whether with detection zone contact judge whether the rotation of encoder meets the requirements by detection shaft coupling detection set.Shaft coupling
Whether detection set contacts with detection zone and can be learnt by the electric current registration situation of change of current measuring instrument.The utility model operation letter
Just, and cost is relatively low, and relevance grade is high.

Specific embodiment
In conjunction with attached drawing, that the utility model is described in further detail is as follows:
Embodiment one
A kind of encoder zero-crossing detecting device is arranged in the shell 2 as shown in Figure 1, including flange 1 and barrel-type casing 2
Have annular detection zone, as shown in Fig. 2, the detection zone is made of conductive metal sheet 7, the conductive metal sheet 7 by screw with
2 inner wall of shell is fixedly connected, and the conductive metal sheet 7 is fitted closely with 2 inner wall of shell.The conductive metal sheet 7
Two sides are connect by conducting wire with current measuring instrument, and the conducting wire is set to inside the shell 2.And the conductive metal sheet 7
It is connect with external power supply.2 outer wall of shell is provided with convex block 3, and sliding slot 4 engaged therewith is fixedly connected with the flange 1,
And the convex block 3 is engaged with the contact surface of the sliding slot 4 by screw thread 8.The utility model further includes shaft coupling detection set 5,
The shaft coupling detection set 5 can be conductive, is fixedly installed on outside shaft coupling 6, shape is regular polygon.In the present embodiment
Shaft coupling detection 5 shapes of set are regular hexagon.
The flange 1 is fixedly installed on encoder.
Shell 2 passes through the cooperation of convex block 3 and sliding slot 4,4 can adjust position along the chute.Screw thread 8 being capable of accurate detent.
When zero point detects, the utility model is assembled by above content, opens power supply, detection zone electrification, while electric current is surveyed
Amount instrument can measure size of current.Normal operating condition, the rotation of shaft coupling 6 will not contact detection zone, i.e. current measuring instrument shows
Number is unchanged.When encoder 1 or the rotation of shaft coupling 6 have error, the rib of shaft coupling detection set 5 can be with inspection when shaft coupling 6 rotates
It surveys area not stop to contact, since shaft coupling detection set 5 can be conductive, so will lead to detection zone electric current disorder, i.e. current measuring instrument
Registration change.
The shaft coupling detection set of the utility model can amplify the operating condition of shaft coupling, if encoder and shaft coupling occur
The deflection of very little, the amplification through shaft coupling detection set, deflection embody more obvious.Pass through detection shaft coupling detection set
Whether with detection zone contact judge whether the rotation of encoder meets the requirements.Whether shaft coupling detection set contacts with detection zone can
It is learnt by the electric current registration situation of change of current measuring instrument.The utility model is easy to operate, and detection effect is good, and cost compared with
Low, relevance grade is high.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization.It can be applied to various fields suitable for the present invention completely.For those skilled in the art,
Other modifications may be easily implemented.Therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and figure shown and described herein with novel.
