The fixing jig 10 has a bottom plate 11 and a top plate 12, and the top plate 12 is mounted on the bottom plate 11. And a top plate 12 is mounted on the bottom plate 11. Wherein the top plate 12 extends horizontally and has vertical support plates 17 at both ends of the top plate 12, and bottom ends of the support plates 17 are connected to the bottom plate 11, so that the top plate 12 is mounted and supported above the bottom plate 11 by the support plates 17. Preferably, the top plate 12 and each of the support plates 17 may be integrally provided.
An inward-sinking mounting groove 13 is formed on the top surface of the base plate 11, the mounting groove 13 is circular, and can be used for mounting a disk motor having a hollow magnetic encoder through a guide circle, and the rotating jig 20 is used for mounting on the disk motor.
And a plurality of stoppers 14 are provided on the base plate, each stopper 14 is substantially rectangular (some of which may be rounded) and is located around the edge of the mounting groove 13, respectively, for positioning the disc motor in the mounting groove 13.
Wherein, each limiting block 14 has a corner extending to the right above the mounting groove 13, and has a lower mounting hole 18 penetrating through the limiting block 14 at the corner, and then the lower mounting hole 18 is also located right above the mounting groove 13, through which the disc motor can be fixedly mounted by using screws.
The top plate 12 has a through-hole 15 and a plurality of upper mounting holes 16, each upper mounting hole 16 being located around the through-hole 15, and the through-hole 15 and each upper mounting hole 16 being located directly above the mounting groove 13. Wherein high-precision optical encoders can be fixedly mounted by using guide circles and screws through the through-holes 15 and the respective upper mounting holes 16.
The top of the rotating jig 20 has a cross-shaft shaped transmission member 21, while on the high precision optical encoder there is also a cross-shaft shaped member, on which the transmission member 21 can be interference fit with the relevant member on the high precision optical encoder at the through-going opening 15 when the rotating jig 20 is mounted on a disc motor.
When the jig is used, the rotating jig 20 is fixedly arranged at the top of the disc motor through screw locking, the disc motor is arranged in the mounting groove 13 on the bottom plate 11 of the fixed jig 10, and then the high-precision optical encoder is arranged on the top plate 12 through the through hole 15 and each mounting hole and is in interference fit with the transmission part 21 on the rotating jig 20.
