DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5 A motor stator and rotor punching device comprises a processing table 1, a support frame 2 is fixedly mounted on the top of the processing table 1, and a turntable 4 for placing the motor stator and rotor punching sheets 3 is provided below the support frame 2, a driving member 6 for driving the turntable 4 to rotate is provided inside the processing table 1, a clamping assembly 7 for fixing the motor stator and rotor punching sheets 3 is provided on the top of the support frame 2, and the clamping assembly 7 also includes a blanking member 8 for blanking.

[0022] In detail, the turntable 4 is driven by the driving member 6 to drive the motor stator and rotor punching sheet 3 to rotate axially, so that multiple punching operations can be performed on the motor stator and rotor punching sheet 3, wherein the punching operation is usually performed at the edge of the motor stator and rotor punching sheet 3, so the drill rod 23 cannot be arranged concentrically with the motor stator and rotor punching sheet 3, so the driving member 6 is required to drive the motor stator and rotor punching sheet 3 to rotate.

[0023] Furthermore, a cylinder 5 is fixedly installed on the top of the support frame 2, and a first motor 22 is fixedly installed on the axial end of the cylinder 5 through a mounting seat 21, and a drill rod 23 is fixedly installed on the output shaft of the first motor 22. The driving member 6 includes a second motor 61 fixedly installed on the top of the inner wall of the processing table 1, and the axial end of the second motor 61 passes through the processing table 1 and is fixedly connected to a positioning rod 62, and the turntable 4 is slidably connected to the positioning rod 62.

[0024] It should be supplemented that a guide groove 621 is provided on the periphery of the positioning rod 62, and a guide block 41 is provided in the sliding groove of the turntable 4, and the guide block 41 is slidably connected to the guide groove 621. The advantage of this is that, through the action of the guide block 41 and the guide groove 621, the turntable 4 can be driven to rotate together with the positioning rod 62 driven by the second motor 61, so that the motor stator and rotor punchings 3 can be driven to follow the rotation;

[0025] Afterwards, because the unloading rack 81 is arranged below the turntable 4, when the unloading rack 81 drives the turntable 4 to rise, the turntable 4 is stopped when it reaches the top of the positioning rod 62 due to the guide block 41, and the top is flush with the positioning rod 62. In this way, on the one hand, the turntable 4 will not separate from the positioning rod 62, and on the other hand, the motor stator and rotor punching sheets 3 are not stopped by the positioning rod 62, which facilitates unloading.

[0026] Furthermore, the clamping assembly 7 includes a pair of support cylinders 71 fixedly installed on the side of the mounting seat 21, a support rod 72 is slidably connected inside the support cylinder 71, and a spring 73 is fixedly connected between the inner bottom surface thereof and the end surface of the support rod 72, and a fixing plate 74 is fixedly installed at the other end of the pair of support rods 72.

[0027] In more detail, the fixing plate 74 is circular in structure and has a through slot 75 at its center point. The drill rod 23 is rotatably connected in the through slot 75 . The side of the fixing plate 74 is provided with a plurality of anti-sliding blocks 76 that can press against the motor stator and rotor punchings 3 .

[0028] The specific operation is that the cylinder 5 drives the first motor 22 and the fixing plate 74 to descend, and the fixing plate 74 will contact the motor stator and rotor punching 3. Then, due to the action of the support rod 72 and the spring 73, the fixing plate 74 uses the anti-sliding block 76 to apply pressure to the motor stator and rotor punching 3, thereby achieving the effect of pressing the motor stator and rotor punching 3.

[0029] The spring 73 can also stabilize the punching process and prevent accidental movement.

[0030] In general, the unloading part 8 includes a unloading rack 81, the top of the unloading rack 81 is located above the first motor 22 and is fixedly connected to the axial end of the cylinder 5, and the bottom is located below the turntable 4 and is slidably connected to the positioning rod 62, one end of the unloading rack 81 can resist and push the turntable 4, and the end away from the turntable 4 is provided with a bending portion 82.

[0031] Finally, a push rod 83 is fixedly installed on the bottom surface of the top of the support frame 2 above the bending portion 82. The push rod 83 is slidably connected to the unloading frame 81 and can contact the motor stator and rotor punching sheets 3 to tilt them.

[0032] It should be noted here that, because the drill rod 23 needs to be punched multiple times, a certain space needs to be reserved between the feed rack 81 and the top of the processing table 1, so as to prevent the feed rack 81 from getting stuck when the drill rod 23 is pressed down to punch holes;

[0033] Furthermore, due to the reason of leaving space, when the drill rod 23 rises and just separates from the motor stator and rotor punchings 3, the unloading rack 81 will not drive the motor stator and rotor punchings 3 to rise.

[0034] The specific operation is that the unloading rack 81 drives the turntable 4 and the motor stator and rotor punching 3 to rise. When the turntable 4 is stuck due to the guide block 41, the motor stator and rotor punching 3 that is separated from the positioning rod 62 will be affected by the resistance of the resistance rod 83 and tilted;

[0035] At this time, because of the bending portion 82, the motor stator and rotor punching sheets 3 are separated from the unloading rack 81 along the bending portion 82, thereby achieving the effect of automatic unloading.

[0036] Working mode: When working, the motor stator and rotor punching sheet 3 and the positioning rod 62 are inserted together and placed above the turntable 4, and the cylinder 5 drives the first motor 22 and the fixed plate 74 to move downward, and cooperates with the second motor 61 to punch the motor stator and rotor punching sheet 3;

[0037] When the fixing plate 74 moves downward and contacts the motor stator and rotor punchings 3, the support rod 72 cooperates with the spring 73 to apply pressure to the fixing plate 74, thereby pressing the motor stator and rotor punchings 3;

[0038] Finally, after the drilling is completed, the cylinder 5 drives the first motor 22 and the unloading rack 81 to rise, and the unloading rack 81 will drive the turntable 4 and the motor stator and rotor punchings 3 to rise when rising. When the turntable 4 is stuck, the motor stator and rotor punchings 3 are separated from the positioning rod 62, and the motor stator and rotor punchings 3 are separated from the unloading rack 81 along the bending part 82 due to the resistance of the resistance rod 83.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
