[0038] Transmission belt 1;

[0039] Stamping mechanism 3 located at the discharging end of transmission belt 1, comprising receiving frame 31 and air cylinder 33 installed at one end of receiving frame 31 and used to drive the push plate 32 sliding on the receiving frame 31 to move;

[0040] Receiving plate 2 movably arranged at the discharging end of transmission belt 1, one end of receiving plate 2 is hinged, and the other end is provided with first resistance spring 21 connected with receiving frame 31.

[0041] Specifically, in the above embodiment, the receiving plate 2 is hinged on the rack, and the receiving frame 31 is installed on the rack.

[0042] In the above technology, the transmission belt 1 transmits the material to the receiving plate 2, when the material is discharged to the receiving plate 2, the receiving plate 2 will be inclined and roll into the receiving frame 31, and then the bearing inner ring is placed in front of the push plate 32, and the bearing inner ring is completed by the air cylinder 33. The structure is simple, convenient and fast to operate, and greatly improves the work efficiency.

[0043] As a further embodiment of the present application, it further comprises bearing inner ring feeding mechanism 4, which comprises feeding cabin 41, push plate 42 slidingly arranged in feeding cabin 41 and pulled to the discharging station by tension spring 43; receiving frame 31 is provided with positioning block 5 arranged symmetrically along the vertical direction, and bearing inner ring discharging positioning groove is formed between positioning block 5 and push plate 32.

[0044] ​Further, the material receiving frame 31 is rotatably provided with a pushing member 6, which comprises a pushing plate 61 and a trigger lever set 62 arranged in perpendicular relationship; the pushing plate 61 is used to make the bearing inner rings be released one by one to the discharging station; the trigger lever set 62 comprises a connecting handle 621 and a push block 622 with an inclined surface, the connecting handle 621 is slidably assembled with the push block 622, and the push block 622 is extended to the moving path of the push plate 32 by the second blocking spring 623 arranged therebetween; the push plate 32 is in blocking engagement with the push plate 32 in the return stroke.

[0045] Further, the positioning block 5 is isosceles triangular structure, one of the apexes is rotatably provided with the material receiving frame 31, and the push plate 32 is tangent to the waist surface in the reciprocating movement of the push plate 32 to make the positioning block 5 rotate and exit.

[0046] Specifically, in the above embodiment, the plurality of bearing inner rings are stacked in the feeding cabin 41, and the pushing plate 42 pulls the bearing inner rings due to the deformation of the tension spring 43. At this time, the pushing plate 61 blocks the bearing inner rings from reaching the discharging station.

[0047] When the cylinder 33 drives the push plate 32 to move, the bearing inner ring in the discharging positioning groove is pushed and moved, and the installation is completed. In the advancing process, the push plate 32 pushes the push block 622 to move close to the connecting handle 621, and makes the second blocking spring 623 deform, so that the push plate 32 is separated, and the push block 622 returns to the state shown in the figure again under the restoration of the second blocking spring 623.

Figure 3 The position shown in the figure is accurate, and the backward movement forms a groove to clamp the rotor.

[0057] As a further embodiment provided by the present application, the push plate 32 is provided with top blocks 322 arranged in a circumferential array and radially movable on one side of the receiving plate 80; a large conical tooth disc 323 with a vortex protrusion arranged on one side surface is arranged in the push plate 32, the large conical tooth disc 323 is connected with the top blocks 322 in meshing connection; an internal hexagonal shaft 324 is rotatably arranged on the push plate 32, and a small conical gear 325 is fixedly installed on the internal hexagonal shaft 324 and in meshing connection with the large conical tooth disc 323.
