[0002] The split encoder is a device that encodes the original signal into a digital signal. It is widely used in industrial automation, robotics, medical equipment, automotive electronics and other fields. This encoder uses two parts placed on the mechanical switch or rotating part, and converts the motion information into a digital signal output by measuring the relative motion between the two parts to achieve accurate measurement, control and transmission. It has the characteristics of simple structure, low cost, small size, flexible installation and high environmental tolerance.

[0003] When installing the stator of the prior art split encoder, due to multiple precision transfers in the installation process, there is a concentricity deviation between the sensing part of the stator and the rotation center of the rotor, which affects the performance of the encoder. Summary of the invention

[0004] In view of the above problems, the present invention provides a split encoder stator high concentricity installation system and method, which is used to solve the problem that when installing the stator of the prior art split encoder, there is multiple precision transfers in the installation process, resulting in concentricity deviation between the sensing part of the stator and the rotation center of the rotor, thereby affecting the encoder performance.

[0010] Preferably, the outer diameter of the conical tooling changes evenly from top to bottom to form conical surfaces and cylindrical inner holes of different sizes.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] The embodiment of the present invention discloses a system for installing a split encoder stator with high concentricity, referring to Figures 1 to 3 A split encoder stator high concentricity installation system includes an encoder installation platform 1, a split encoder body 2 and a conical tooling 3.

[0028] The encoder mounting platform 1 includes a stator mounting seat 101 and a rotor mounting shaft 102; the split encoder body 2 includes a stator 201 and a rotor 202; and a conical tooling 3. The conical tooling 3 has an inner hole 301 and a conical surface 302. The stator 202 is fixedly mounted on the rotor mounting shaft 102. Since the rotor mounting shaft 102 has a high dimensional accuracy and a stable center of rotation, the rotor 202 can be fixed and driven to rotate, and the sensing part in the rotor 202 is highly coaxial with the center of rotation; the stator mounting seat 101 is used to fix the stator, but the alignment relationship between the stator and the rotor 202 cannot be guaranteed; the conical tooling 3 is in the shape of a conical funnel that changes evenly and continuously from top to bottom. The conical funnel-shaped design makes the conical surface 302 of the conical tooling 3 have a continuously changing major and minor diameter from top to bottom, and the conical surface 302 of the conical tooling 3 is highly coaxial with its inner hole 301.

[0029] The performance of the split encoder body 2 is greatly affected by the installation deviation, especially the installation deviation of the stator. The conical fixture 3 has an inner hole 301 that matches the rotor installation shaft 102 with high precision, and the size range from the large diameter to the small diameter of the conical surface 302 of the conical fixture 3 covers the inner diameter of the stator 201. In the process of installing and fixing the stator 201, the conical fixture 3 is used for guidance and limiting, and the inner ring of the stator 201 can be highly coaxial with the conical surface 302 of the conical fixture 3. Because the conical surface 302 of the conical fixture 3 is highly coaxial with its inner hole 301, and the inner hole 301 of the conical fixture 3 and the rotor installation shaft 102 achieve precise hole-shaft matching, the conical surface 302 of the conical fixture 3 and the rotor 201 installation shaft have high coaxiality, and finally achieve a high coaxiality between the inner ring of the stator 201 and the rotor 201 installation shaft.

[0030] With the help of the conical tooling 3, the sensing parts between the stator 201 and the rotor 202 have a good alignment relationship, and the performance of the split encoder is fully utilized.

[0031] Reference Figure 4 In order to realize the installation of the above-mentioned split encoder stator high concentricity installation system, the present embodiment further discloses an installation method of the split encoder stator high concentricity installation system. The above-mentioned installation method of the split encoder stator high concentricity installation system includes the following steps:

[0032] S1, the rotor 202 is sleeved and fixed on the rotor mounting shaft 102;

[0033] S2, the stator 201 is pre-installed on the stator mounting seat 101;

[0034] S3, the conical tooling 3 is set on the rotor mounting shaft and pressed until the stator inner ring and the tooling conical surface are in close contact with each other without air gap;

[0035] S4, the stator 201 is fixedly mounted on the stator mounting seat 101;

[0036] S5, take out the tooling.

[0037] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
