Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-2 A milling device for grooves on the end face of a motor shaft includes a base 1. A vertical plate 2 is fixedly connected to the upper edge of the base 1. A top plate 3 is fixedly connected to the top of the vertical plate 2. A hydraulic cylinder 4 is fixedly installed on the upper end of the top plate 3. The piston rod of the hydraulic cylinder 4 passes through the top plate 3 and is slidably connected to the top plate 3. A movable pressure seat 5 is fixedly connected to the end of the piston rod of the hydraulic cylinder 4. A guide frame 14 is fixedly connected to the movable pressure seat 5. The guide frame 14 passes through the top plate 3 and is slidably connected to the top plate 3. The guide frame 14 guides the lifting and lowering of the movable pressure seat 5. A support column 6 is fixedly connected to the middle of the upper end of the base 1. A fixed pressure seat 7 is fixedly connected to the top of the support column 6. The fixed pressure seat 7 abuts against the movable pressure seat 5. A guide groove 8 is fixedly connected to the right side of the fixed pressure seat 7. A support frame 10 is fixedly connected to the right side of the base 1. A hydraulic cylinder 11 is fixedly installed on the vertical part of the support frame 10. The piston rod of the hydraulic cylinder 11 is slidably connected to the guide groove 8.
[0021] Please see Figures 1-4A feeding mechanism 9 is provided on the top plate 3. This mechanism enables continuous feeding, thus achieving continuous production. The feeding mechanism 9 includes a hopper 91 fixedly connected to the top plate 3, with the hopper 91 corresponding to the guide chute 8. A limit pin 92 is slidably connected to the side wall of the hopper 91, and the limit pin 92 penetrates the hopper 91. A guide rod 93 is fixedly connected to the limit pin 92, penetrating the vertical plate 2 and slidably connected to it. A stroke limit plate 12 is fixedly connected to the rod of the hydraulic cylinder 2 11, and a push rod 13 is fixedly connected to the stroke limit plate 12. An inclined groove is formed inside the limit pin 92, and the position of the inclined groove corresponds to the push rod 13. After the push rod 13 enters the inclined groove of the limit pin 92, it can apply an axial thrust of the guide rod 93 to the limit pin 92. A spring 95 is sleeved on the outer side of the guide rod 93. One end of the spring 95 is fixedly connected to the limiting pin 92, and the other end is fixedly connected to the surface of the upright plate 2.

[0022] The specific implementation process of this utility model is as follows: In use, the whole is placed on a milling machine, and then the motor shaft blank is stored in the hopper 91. Subsequently, the piston rod of the hydraulic cylinder 2 11 extends. At this time, the stroke limit plate 12 on the piston rod of the hydraulic cylinder 2 11 drives the push rod 13 to move. The push rod 13 will be inserted into the inclined groove of the limit pin 92, thereby causing the limit pin 92 to move laterally. The limit pin 92 then compresses the spring 95. At this time, the blank in the hopper 91 falls and falls into the guide groove 8. Then the piston rod of the hydraulic cylinder 2 11 resets. At this time, the limit pin 92 resets and blocks the subsequent blank in the hopper 91. This process is repeated to achieve the purpose of automatic feeding and continuous production. Moreover, when the piston rod of the hydraulic cylinder 2 11 moves again, it will push the blank in the guide groove 8 into the fixed pressure seat 7. Then the hydraulic cylinder 1 4 pushes the movable pressure seat 5 downward to clamp and fix the motor shaft blank, which facilitates the milling of its end face.
