[0033] Such asFigures 1 to 7 As shown in the figure, a blanking device for a bearing cage includes a blanking bin, a conveying mechanism, and a blanking cylinder 13. The blanking bin includes a rotating base 1, a blanking ring 2, a material-passing rod 3, and a return spring 5. The blanking ring 2 is installed on the rotating base 1 and reset by the return spring 5. A blanking hole 101 is provided on the rotating base 1 opposite to the inner hole of the blanking ring 2. The first end of the material-passing rod 3 is detachably connected to the positioning disk 4, so as to facilitate replacing the material-passing rod 3 according to different models of bearing cages. The second end of the material-passing rod 3 is located above the blanking ring 2. In this embodiment, there are 6 material-passing rods 3, that is, there are 6 working stations. The conveying mechanism includes a pushing component 9 and a position sensor 12. The pushing component 9 is driven by a conveying cylinder 11 to move on the conveying track 10, and the position sensor 12 is installed at the head and the end of the conveying track 10. The blanking cylinder 13 is installed at one end of the conveying track 10 close to the rotating base 1 on the side and is used to drive the blanking ring 2 to carry out blanking. During operation, each material-passing rod 3 is strung with full bearing cages. When the rotating base 1 rotates to the working station facing the conveying mechanism, the bearing cages on the material-passing rod 3 at the working station are sequentially blanked from the blanking ring 2, fall through the blanking hole 101 onto the conveying track 10, and then are pushed by the pushing component 9 to the blanking hole 1001 on the conveying track 10 to enter the next process. After the blanking of the bearing cages on the first material-passing rod 3 is completed, the rotating base 1 rotates one working station to carry out the blanking of the bearing cages on the second material-passing rod 3. At this time, the first material-passing rod 3 can be removed and strung with bearing cages again. In this way, the blanking of the bearing cages at 6 working stations is carried out in sequence, thereby improving the working efficiency.

[0034] In one embodiment, the rotating base 1 is connected to the servo motor 6 through a gear set. The servo motor 6 drives the rotating base 1 to rotate through the gear set. When the servo motor 6 rotates a certain angle, it can drive the gear set and the rotating base 1 to rotate a certain angle, thereby realizing the switching of working stations.

[0035] In one embodiment, at least two columns 7 are installed between the rotating base 1 and the positioning disk 4 to support the rotating base 1 and the positioning disk 4.

[0036] In one embodiment, the material-passing rod 3 is made of aluminum alloy material to prevent scratches on the bearing cage caused by the outer diameter of the material-passing rod 3. The material-passing rod 3 has different diameter specifications to adapt to different models of bearing cages.

[0037] In one embodiment, a number of U-shaped grooves 401 are provided on the outer edge of the positioning disk 4. The first end of the material-passing rod 3 is detachably installed on the fixed base 301 through an inner hexagon screw. The fixed base 301 is installed in the U-shaped groove 401. The diameter of one end of the fixed base 301 is larger than the diameter of the U-shaped groove 401, so that the material-passing rod 3 can be stuck in the U-shaped groove 401, which is convenient for disassembly.

[0038] In one embodiment, the blanking ring 2 includes an outer ring 201, an inner ring 202, a telescopic block 203, and a spring 204. The inner ring 202 is fixed to the rotating base 1 and installed inside the outer ring 201. A push rod 205 and a pull rod 206 are respectively arranged on the outer periphery of the outer ring 201. A plurality of telescopic blocks 203 are arranged along the circumferential direction of the inner ring 202. Wedge-shaped grooves matching the number of the telescopic blocks 203 are formed in the circumferential direction of the inner ring 202. The telescopic blocks 203 are slidably installed in the wedge-shaped grooves. An arc-shaped groove is formed along the circumferential direction of the outer diameter of the inner ring 202. Two springs 204 are sleeved in the arc-shaped groove on the outer periphery of the inner ring 202. One end of the telescopic block 203 abuts against the spring 204. At the same time, an arc-shaped groove is also formed in the inner wall of the outer ring 201 corresponding to the position of the spring 204. The whole groove formed by the two arc-shaped grooves of the outer ring 201 and the inner ring 202 after installation is slightly smaller than the spring 204, which is equivalent to the interference fit of a hole and a shaft. In this way, when the outer ring 201 rotates, it can drive the spring 204 to be tensioned and relaxed. In the initial state, the spring 204 is in a tensioned state and the telescopic block 203 is in an extended state. At this time, the inner diameter of the blanking ring 2 is smaller than the outer diameter of the bearing cage, and the bearing cage cannot fall. When the piston rod of the blanking cylinder 13 extends and pushes the push rod 206, the outer ring 201 rotates. At this time, the spring 204 is in a relaxed state and the telescopic block 203 retracts. At this time, the inner diameter of the blanking ring 2 is larger than the outer diameter of the bearing cage, and the bearing cage falls.

[0039] In one embodiment, the first end of the return spring 5 is connected to the pin on the pull rod 206, and the second end of the return spring 5 is connected to the fixed pin 8 installed on the rotating base 1. The blanking cylinder 13 pushes the push rod 205 to drive the outer ring 201 to rotate along the inner ring 202, so that the spring 204 is in a relaxed state and the telescopic block 203 retracts. Then the bearing cage falls from the hole of the blanking ring 2. Under the action of the return spring 5, the outer ring 201 returns to its original position, and the telescopic block 203 also returns to its original position and is in an extended state, and the bearing cage cannot fall.

[0040] In one embodiment, the material pushing assembly 9 includes a material pushing plate 901, a cantilever 902, and a connecting plate 904. The material pushing plate 901 and the connecting plate 904 are respectively installed on the cantilever 902 by screws. The material pushing plate 901 is an L-shaped structure and is located on the conveying track 10. The front end of the material pushing plate 901 has a polyurethane protective layer to prevent damage to the appearance of the bearing cage during the material pushing process. The connecting plate 904 is located on one side of the conveying track 10, and the driving end of the cylinder 11 is connected to the connecting plate 904. The conveying cylinder 11 drives the connecting plate 904 to drive the material pushing plate 901 to move on the conveying track 10, and then pushes the bearing cage to the blanking hole 1001 at the end of the conveying track 10. The end of the conveying track 10 has a protruding step for limiting, which can prevent the bearing cage from slipping out of the conveying track 10 during the movement.

[0041] In one embodiment, the pusher assembly 9 further includes a guide shaft 903. One end of the guide shaft 903 is connected to the cantilever 902, and the other end is installed on the mounting plate 14 located at the head end of the conveying track 10 through a linear bushing 905.

[0042] In one embodiment, an oil buffer 15 is installed on the mounting plate 14 to reduce the impact when the connecting plate 904 reaches the front end of the conveying track 10, thereby extending the service life of the conveying cylinder 11.

[0043] The above are the preferred embodiments of the present utility model. Those skilled in the art to which the present utility model pertains can also make changes and modifications to the above embodiments. Therefore, the present utility model is not limited to the above specific embodiments, and any obvious improvements, substitutions or variations made by those skilled in the art based on the present utility model fall within the protection scope of the present utility model.
