[0038] like Figures 1-6 As shown, a magnetic ring flipping device for a chamfering machine includes a flipping drive device 1, a base 2, a gripper 3, and a gripping drive device 4.

[0039] The flipping drive device 1 is installed on one side of the base 2, the gripping drive device 4 is installed on the top of the base 2, and the gripper 3 is rotatably disposed on the bottom of the base 2.

[0040] The clamping drive device 4 is used to drive the jaws 3 to open and clamp the magnetic ring 10, and the flipping drive device 1 is used to drive the jaws 3 to rotate so as to flip the magnetic ring 10.

[0041] In this embodiment, a magnetic ring flipping device for a chamfering machine is installed on the chamfering machine to assist the chamfering machine in flipping the magnetic ring 10 180 degrees. After the chamfering machine has chamfered one side of the magnetic ring 10, the material picking device on the chamfering machine will remove the magnetic ring 10 and then send the magnetic ring 10 to the gripper 3 of the magnetic ring flipping device.

[0042] In the initial state, the gripper 3 is in a closed state. Therefore, when the magnetic ring 10 is sent to the gripper 3, the gripping drive device 4 needs to drive the gripper 3 to open in order to grip the magnetic ring 10. After the magnetic ring 10 is gripped by the gripper 3, the flipping drive device 1 drives the gripper 3 to rotate 180 degrees, thereby flipping the magnetic ring 10 180 degrees. Then the chamfering machine continues to chamfer this side of the magnetic ring 10. Finally, the chamfering machine completes the chamfering process on both sides of the magnetic ring 10.

[0043] Compared with the prior art, the magnetic ring turning device can turn the magnetic ring on the chamfering machine by 180 degrees, and improve the chamfering efficiency of the chamfering machine on the two surfaces of the magnetic ring.

[0044] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0045] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0046] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0047] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0048] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0049] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0050] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0051] Further, the turning driving device 1 comprises a first air cylinder 11 and a turning rack 12;

[0052] The through hole 131 is opposite to the long hole 121, which ensures that the telescopic rod 111 of the first air cylinder 11 can drive the turning rack 12 to move in the long hole 121 in a transverse reciprocating manner. The long hole 121 is arranged to ensure that the turning rack 12 can be constrained to move in the long hole 121 in a transverse reciprocating manner, thereby ensuring that the turning rack 12 can be stably engaged with the rotating shaft rack 51, and the turning rotating shaft 5 can be stably rotated.

[0053] Further, the turning rack baffle 14 is further arranged on one side wall of the seat body 2 relative to the air cylinder mounting box 13, and the turning rack baffle 14 can cover the long hole 121 on the side wall of the seat body 2.

[0054] By arranging the turning rack baffle 14, on the one hand, the turning rack baffle 14 has a sealing effect, mainly sealing the long hole 121. Because the long hole 121 is transversely through the seat body 2 during processing, one end of the long hole 121 is opposite to the through hole 131, and the end of the long hole 121 is mainly used for the telescopic rod 111 of the first air cylinder 11 to pass through, so the end is not sealed. However, the other end of the long hole 121 is located on a side wall of the seat body 2, so the turning rack baffle 14 is arranged to cover the end of the long hole 121 to avoid dust from entering the long hole 121 and affecting the normal operation of the turning rack 12.

[0055] Meanwhile, the turning rack baffle 14 also has a limiting effect. The inner side of the turning rack baffle 14 is provided with an inner counterbore 141, which plays a certain limiting effect on the turning rack 12 during transverse reciprocating movement.

[0056] Further, the outer wall of the turning rotating shaft 5 is provided with a bearing 52 and a sealing ring 53. The sealing ring 53 is located on the outside of the bearing 52, and the rotating shaft rack 51 is located on the inside of the bearing 52.

[0057] The bearing 52 plays a supporting role in the rotation of the turning rotating shaft 5, making the turning rotating shaft 5 rotate more smoothly. By arranging the sealing ring 53, dust can be prevented from entering the bearing 52, thereby ensuring the working precision of the bearing 52. The number of bearings 52 and sealing rings 53 in the embodiment is two respectively. The rotating shaft rack 51 is located on the inside of the bearing 52, and the rotating shaft rack 51 is located between the two bearings 52.

[0058] Further, the clamping jaw pull rod 6 is further arranged. The inside of the turning rotating shaft 5 is hollow, the rod body of the clamping jaw pull rod 6 passes through the inside of the turning rotating shaft 5, and one end of the clamping jaw pull rod 6 protrudes from the top of the turning rotating shaft 5.

[0059] The turning shaft 5 is internally provided with an elastic member 7, the elastic member 7 is sleeved on the clamping jaw pull rod 6, the other end of the clamping jaw pull rod 6 is provided with a clamping jaw limiting head 61, the clamping jaw limiting head 61 protrudes from the bottom of the turning shaft 5;

[0060] The bottom of the turning shaft 5 is also provided with a clamping jaw mounting arm 54, the clamping jaw 3 and the clamping jaw mounting arm 54 are each provided with an axle hole 501;

[0061] Further comprising a connecting shaft, the connecting shaft passes through the axle hole 501 of the clamping jaw 3 and the clamping jaw mounting arm 54 respectively, and the clamping jaw 3 is openably and closably mounted in the clamping jaw mounting arm 54;

[0062] The left and right sides of the clamping jaw limiting head 61 are provided with limiting notches 610, and the inner side of the clamping jaw 3 is provided with limiting protrusions 31 which are used in cooperation with the limiting notches 610.

[0063] In the initial state, the clamping jaw 3 is in a closed state, because the clamping jaw pull rod 6 is pulled up by the elastic member 7, so that the limiting protrusions 31 of the clamping jaw 3 cooperate with the limiting notches 610, and the clamping jaw 3 is in a closed state.

[0064] The clamping jaw mounting arm 54 is mainly arranged for openably and closably mounting the clamping jaw 3 in the clamping jaw mounting arm 54, and the connecting shaft is an existing component, so it is not shown in the figure.

[0065] Further, the elastic member 7 is a disc spring.

[0066] If the disc spring is used, it has a large pulling force, and can more easily pull up the clamping jaw pull rod 6, so that the clamping jaw 3 is in a closed state.

[0067] Further, the bottom surface of the clamping jaw limiting head 61 and the bottom surface of the clamping jaw mounting arm 54 are arc surfaces.

[0068] Because the shape of the magnetic ring 10 is circular, the bottom surface of the clamping jaw limiting head 61 and the bottom surface of the clamping jaw mounting arm 54 are arc surfaces, which can fit the shape of the magnetic ring 10, and when the clamping jaw 3 clamps the magnetic ring, the shape of the magnetic ring 10 is not easily damaged, thereby protecting the shape of the magnetic ring 10.

[0071] Because in the initial state, the jaw pull rod 6 is pulled up by the disc spring, the jaw 3 is in a closed state, when it is needed to open the jaw 3 to clamp the magnetic ring 10, specifically, the second cylinder 41 drives the top opener 42 to press down, the top opener 42 touches the end of the jaw pull rod 6, then the top opener 42 continues to press down, the jaw pull rod 6 overcomes the pulling force of the disc spring, so that the jaw 3 is opened under the cooperation of the limiting convex head 31 of the jaw 3 and the limiting recess 610.

[0072] Then, the magnetic ring 10 is sent into the jaw 3, the second cylinder 41 drives the top opener 42 to move away from the end of the jaw pull rod 6, until the top opener 42 is not in contact with the end of the jaw pull rod 6, under the pulling force of the disc spring, the jaw pull rod 6 is pulled up again, at this time, the jaw 3 successfully clamps the magnetic ring 10 under the cooperation of the limiting convex head 31 of the jaw 3 and the limiting recess 610.

[0073] The top opener 42 of the embodiment is a top opening screw, which is more easily fixed on the output end of the second cylinder 41.
