Description
Technical field
The present invention relates to a kind of coaxial positioning rule for the assembly of rotary encoder Circular gratings, belong to machinery field, specifically
For coaxial positioning adjustment of the rotary encoder Circular gratings in assembly.
Background technique
High precision photoelectric encoder is the important component in photogoniometer device, in encoder production process, circle
Grating and encoder spindle mounted are an important link during photoelectric encoder is manufactured, the practical centre of gyration of Circular gratings
It is difficult to be overlapped with the centre of gyration of encoder main shaft, there are certain coaxiality errors, so needing the concentricity to Circular gratings
It is adjusted, minimizes coaxiality error, realize the accurate of encoder output.
At present in enterprise, adjusting the method that concentricity uses in Circular gratings assembling process is: on encoder main shaft
Circular gratings axial locating surface on smear a small amount of glue, Circular gratings are placed on axial locating surface, pressing device is then used
Circular gratings are pressed on axial locating surface, then the encoder for being equipped with Circular gratings are placed under high magnification numbe enlarging lens, mirror
Head is connected with video screen, and the code channel basic circle of such Circular gratings is just shown on the tv screen, has a reference line on screen, so
The rotating shaft for starting artificially to can be manually rotated encoder afterwards drives Circular gratings rotation, and when encoder rotation, basic circle has with reference line
When intersect, it is sometimes tangent, have phase from, this just illustrate Circular gratings the centre of gyration and encoder main shaft the centre of gyration exist compared with
Big coaxiality error indicates that product is unqualified.It is known that no matter how Circular gratings rotate when coaxiality error is zero,
The basic circle of Circular gratings all can be tangent with reference line always.Certainly, coaxiality error is to can reduce but cannot eliminate.Therefore, exist
In actual production process, worker needs lightly to beat the edge of grating to center of circle direction manually, and one side eyes look at screen, such as
Basic circle on fruit Circular gratings is always on the screen in a defined section of reference line or so, then it represents that product is qualified, at this time
The concentricity adjustment of encoder Circular gratings finishes.Such method has the disadvantage in that concentricity adjustment of the Circular gratings in assembly
The subjective operation that precision is completely dependent on worker is horizontal, and there are many randomnesss, can directly reduce the effect of concentricity adjustment.Separately
Outside, for a long time, the labor intensity of worker is very big, and worker is be easy to cause to feel exhausted, and reduces regulated efficiency, increases life
Produce cost.So that there is an urgent need to a kind of structures is simple, cost is low and easily operated concentricity adjusts device.
Summary of the invention
It is above-mentioned to solve the object of the present invention is to provide a kind of coaxial positioning rule for the assembly of rotary encoder Circular gratings
The Circular gratings proposed in background technique concentricity in assembly adjusts problem complicated for operation and low regulated efficiency.
To achieve the above object, the technical solution adopted by the present invention is that: it is a kind of for rotary encoder Circular gratings assembly
Coaxial positioning rule, including positioning rule main body, clump weight and axial compression piece, the positioning rule main body the center point are provided in benchmark
Heart hole and radial positioning hole are provided with equally distributed four light projector holes, the radial positioning around the reference center hole
Hole lower end is provided with tapered surface；The clump weight is mounted on the top of the positioning rule main body, institute by the connection type being glued
State the lower section that axial compression piece is mounted on the reference center hole by the connection type being glued.
Preferably, the clump weight is provided with gripper hole, and the gripper hole is for the connection with manipulator.
Preferably, the axial compression piece uses plastics that be not easy to be bonded, slightly flexible, in Circular gratings assembling process
In be used to Circular gratings carry out axial compression.
Preferably, four light projector holes are used for the process of ultraviolet light projection.
Preferably, the positioning rule main body is ring bodies structure, and the reference center hole, radial positioning hole and tapered surface are same
Axis, positioning rule main body, reference center hole, radial positioning hole, tapered surface and the light projector hole are an integral structure.
Compared with prior art, beneficial effects of the present invention: the coaxial positioning rule structure is simple, convenient to use, mentions
The efficiency that high Circular gratings are coaxially positioned in assembly；The designed tapered surface of the coaxial positioning rule, in Circular gratings assembling process
It is middle that axial force is converted to a part of radial force, Circular gratings are radially adjusted to exact position, Circular gratings is realized and was assembling
Rapid coaxial in journey positions purpose.
