Description

Technical Field

[0001] The utility model relates to the technical field of rotor processing, in particular to a rotor punching sheet rapid punching device. Background Art

[0002] Motor rotor stampings are usually made of 0.5mm thick silicon steel sheets laminated together and then fixed on the rotor bracket or shaft. They are widely used in stepper motors, AC and DC motors, reduction motors, outer rotor motors, shaded pole motors, synchronous asynchronous motors, etc.

[0003] Stamping equipment is used for processing during the production of motor rotors, so as to improve the overall performance of the motor. However, the current stamping equipment requires the operator to place the rotor on a limit seat during operation, and then move the stamping part down to process the rotor. The operator needs to manually remove the processed rotor and place a new rotor to be processed on the limit seat. This processing method requires the operator to manually install and replace the rotors one by one under the stamping part, which increases the operator's work intensity. If the operator accidentally opens the stamping part when replacing the rotor, the operator's safety cannot be guaranteed, which not only affects the efficiency and level of rotor processing, but also makes the operator's safety cannot be guaranteed.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figure 1-Figure 3, a rapid stamping device for rotor punching sheets, including a base 1, on which a first motor 2 is fixedly installed, and the output end of the first motor 2 is fixedly connected to a connecting rod 3, and the output end of the connecting rod 3 is fixedly connected to a support platform 4. The base 1 is of a C-shaped structure, and the connecting rod 3 is vertically arranged. The support platform 4 is of a circular structure;

[0021] It should be noted that the model of the first motor 2 is Y90S-2, the model of the second motor 13 is Y80M1-2, and the stamping part 6 can punch the rotor, which is an existing technology. The rotation angle of the first motor 2 after driving is 45 degrees each time;

[0022] Four clamping seats 5 for supporting the rotor are integrally connected to the support platform 4. A stamping part 6 for punching the rotor is installed on the base 1. Positioning holes 7 and through holes are respectively opened in the clamping seats 5, and positioning columns 8 extending into the positioning holes 7 and used for limiting the central hole of the rotor are placed in the clamping seats 5. By sleeving the central hole of the rotor on the positioning columns 8, the rotor will not be displaced during processing;

[0023] By arranging four clamping seats 5 on the support platform 4, the first motor 2 can intermittently drive the rotor to move to the position below the stamping part 6. The stamping part 6 can be intermittently opened through an external device to punch the rotor below. Through the mutual cooperation of the first motor 2 and the second motor 13, the rotor can move intermittently and be processed intermittently, thereby improving the processing efficiency and level of the rotor;

[0024] A rubber ring 9 that is movably abutted against the positioning hole 7 is embedded on the positioning column 8. The positioning column 8 is vertically arranged, and a fixing bolt detachably connected to the positioning column 8 is fixedly installed on the clamping seat 5. By realizing the detachable installation of the positioning column 8, different specifications of positioning columns 8 can limit different specifications of rotors, thereby increasing the adaptability of the equipment;

[0025] Racks 10 arranged symmetrically are movably sleeved in the clamping seats 5, and the output ends of the racks 10 are fixedly connected to a limiting block 11 and a soft pad 12 that are integrally connected and used for supporting the rotor. The positioning hole 7 is horizontally opened between the two through holes, and the limiting block 11, the soft pad 12, and the racks 10 extend to the upper positions outside the through holes. A driving component for driving the racks 10 is installed in the clamping seats 5;

[0026] The driving assembly includes a guide rod fixedly installed in the holder 5 and used to guide the rack 10, and a motor 2 13 is fixedly installed in the holder 5, and a rotating shaft 14 is fixedly connected to the output end of the motor 2 13, and a gear 15 symmetrically arranged and meshing with the rack 10 is fixedly installed on the rotating shaft 14, and the rotating shaft 14 is horizontally arranged, and the two guide rods are correspondingly arranged vertically. The guide rod guides the rack 10, so that the rack 10 can smoothly pull the limit block 11 and the cushion 12 when moving. The motor 2 13 below is immediately turned on after the rotor is processed, so that the limit block 11 and the cushion 12 can lift the rotor after moving, so that the operator can take the rotor more conveniently, and the motor 2 is driven by the operator to move out of the position below the stamping part 6 when placing and replacing the rotor, so as to avoid replacing and taking the rotor below the stamping part 6, which may cause the operator's safety to be unguaranteed, so that the operator's safety is guaranteed when placing and replacing the rotor.

[0027] The functional principle of the utility model can be explained through the following operation modes:

[0028] The operator selects the size of the positioning column 8 according to the type of rotor;

[0029] Press the matching positioning column 8 into the positioning hole 7 so that the rubber ring 9 can seal the positioning hole 7 after moving down, and use the fixing bolt to fix the card seat 5 and the positioning column 8;

[0030] When the four positioning columns 8 are installed;

[0031] Place the rotors on the four holders 5 respectively through the positioning columns 8;

[0032] The output end of the motor 2 drives the connecting rod 3 to rotate intermittently, so that the connecting rod 3 drives the support platform 4 to move the rotor to the position below the stamping part 6. When the motor 2 stops rotating, the stamping part 6 can perform stamping processing on the rotor;

[0033] After the stamped rotor is processed, the motor 1 2 continues to drive the support table 4 to rotate intermittently, and moves the next holder 5 and the rotor to the position below the stamping part 6, so that the stamping part 6 can process the rotor during the intermittent movement;

[0034] At the same time, when the stamped rotor moves to one side, the output end of the second motor 13 drives the shaft 14 to rotate, so that the shaft 14 drives the gear 15 to pull the two racks 10, so that the racks 10 and the limit block 11 slide on the guide rod and drive the cushion 12 to resist the rotor through the through hole, so that the stamped rotor is lifted;

[0035] When the processed rotor moves to the opening position of the base 1 again, the operator can remove the processed rotor, the motor 2 13 drives the cushion 12 back to the initial position, and places a new rotor to be processed on the holder 5;

[0036] Repeat the above steps to complete the machining of the rotor.

[0037] 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.
