[0024] As Figures 1-4As shown, a rotor magnetic steel auxiliary feeding jig, comprising a guide seat 1 and a plurality of guide through holes 101 arranged along the axial direction thereof. It should be noted that the plurality of guide through holes 101 are respectively corresponding to the magnetic steel grooves on the motor rotor one by one, that is, when the operator places a plurality of magnetic steels in the guide through holes 101 on the guide seat 1, the relative positions of the plurality of magnetic steels are the same as the relative positions of the plurality of magnetic steel grooves on the motor rotor. And the outer periphery of the guide seat 1 is provided with a plurality of limiting installation holes 102 corresponding to the guide through holes 101 one by one and communicating with each other, the limiting installation hole 102 is slidably connected with the pressing block 2, and the guide seat 1 is provided with an elastic supporting mechanism capable of driving one end of the pressing block 2 to extend into the guide through hole 101, so that the operator can drive the pressing block 2 to abut against the surface of the magnetic steel through the elastic supporting mechanism during the process of inserting the magnetic steel into the guide through hole 101, so as to fix the position of the magnetic steel on the guide seat 1, prevent the magnetic steel from accidentally falling off from the guide seat 1. At the same time, during the process of inserting the magnetic steel into the guide through hole 101 by the operator, since one end of the pressing block 2 extends into the guide through hole 101, a first inclined chamfer 201 is arranged on the side edge of the guide through hole 101 facing the two ends of the guide through hole 101, so that during the process of moving the magnetic steel along the axial direction of the guide seat 1 and inserting it into the guide through hole 101, after the one end of the magnetic steel contacts the surface of the first inclined chamfer 201 on the pressing block 2, the magnetic steel is continuously pressed down, the pressing block 2 can be reversely pushed to retract into the limiting installation hole 102, so that the magnetic steel can be inserted into the guide through hole 101.

[0025] In actual application, the magnetic steel can be inserted into the guide through hole 101 on the guide seat 1 by manual or robot before the to-be-assembled product is accurately moved and fixed directly below the guide jig, so that when the to-be-assembled product is accurately moved and fixed directly below the guide jig, the magnetic steel in the guide through hole 101 can be directly pressed down (this operation can be realized by existing technology), so that the magnetic steel is accurately embedded into the magnetic steel groove on the motor rotor. It should be noted that the distance between the outer periphery of the magnetic steel placed in the guide through hole 101 and the inner wall of the guide through hole 101 is 0.01mm-0.1mm, so as to meet the precision requirement of magnetic steel assembly. By using the rotor magnetic steel auxiliary feeding jig in the technical solution, the pre-assembly operation of the magnetic steel on the guide seat 1 can be realized, the operation process is simplified, and the assembly efficiency is improved, and the precision of magnetic steel assembly is also guaranteed.

[0026] As described above, Figure 3As shown, the elastic supporting mechanism comprises a baffle 3 connected to the outer periphery of the guide seat 1 and a supporting spring 4 arranged horizontally along the moving direction of the pressing block 2, and the two ends of the supporting spring 4 abut against the baffle 3 and the pressing block 2 respectively. Specifically, the baffle 3 is detachably connected to the outer periphery of the guide seat 1 by bolts, that is, bolts can be threaded through the baffle 3, and one end of the bolt threaded through the baffle 3 can be threadedly connected with the guide seat 1, so as to facilitate the installation of the supporting spring 4. At the same time, the supporting spring 4 is arranged along the moving direction of the pressing block 2, so that the elastic force accumulated when the supporting spring 4 is compressed can fully act on the pressing block 2, and one end of the pressing block 2 can stably abut against the surface of the magnetic steel located in the guide through hole 101.

[0027] Further, as shown in Figure 1 , Figure 3 the baffle 3 can block the end opening of the limiting installation hole 102 located on the outer periphery of the guide seat 1, so as to prevent foreign matters from entering the limiting installation hole 102 and affecting the moving state of the pressing block 2. At the same time, the limiting hole 202 for embedding the end of the supporting spring 4 is arranged on the pressing block 2, so as to limit the direction of compression or extension of the supporting spring 4.

[0028] It should be noted that in the present embodiment, the limiting installation hole 102 and the pressing block 2 are both T-shaped, and when the stepped surface on the pressing block 2 abuts against the stepped surface of the limiting installation hole 102, one end of the pressing block 2 extends into the guide through hole 101, and the inclined surface of the first inclined chamfer 201 can be simultaneously located within the range covered by the limiting installation hole 102 and the guide through hole 101, so that the magnetic steel can contact the inclined surface of the first inclined chamfer 201 when inserted into the guide through hole 101. In the present technical solution, the inclination angle of the first inclined chamfer 201 is 10°-25°, as shown in Figure 3 the inclination angle is the included angle between the axial direction of the guide seat 1 and the inclined surface of the first inclined chamfer 201.

[0029] Further, as shown in Figure 4 the edge of the opening end of the guide through hole 101 is provided with a second inclined chamfer 103 for guiding the insertion of the magnetic steel into the guide through hole 101.

[0030] Further, the guide seat 1 is provided with two positioning pins 5, and the axial direction of the positioning pin 5 is parallel or even coincides with the axial direction of the guide seat 1. The positioning pin 5 can be quickly inserted and positioned with the machine table, rack and other equipment on the production line, so as to facilitate the quick disassembly and replacement of the rotor magnetic steel auxiliary feeding jig on the production line, and meet the production requirements.

[0031] Working principle: before the to-be-assembled product is accurately moved and fixed directly below the guide fixture, the magnetic steel can be inserted into the guide through hole 101 on the guide seat 1 by manual or robot, in the process of inserting the magnetic steel into the guide through hole 101, when one end of the magnetic steel contacts the surface of the first inclined chamfer 201 on the pressing block 2 and continues to press the magnetic steel, the magnetic steel can reversely push the pressing block 2, so that the pressing block 2 is retracted into the limiting installation hole 102, thereby compressing the supporting spring 4, and the compressed supporting spring 4 can drive one end of the pressing block 2 to abut against the magnetic steel in the guide through hole 101, thereby limiting the magnetic steel in the guide through hole 101, realizing the pre-assembly of the magnetic steel on the guide seat 1. When the to-be-assembled product is accurately moved and fixed directly below the guide fixture, the magnetic steel in the guide through hole 101 can be directly pressed down, so that the magnetic steel is accurately embedded in the magnetic steel groove on the motor rotor. Therefore, the operation process is simplified, and the assembly efficiency is improved.
