[0002] In the field of motor manufacturing, the hook commutator is the core component of DC motor, and its performance directly affects the motor's operating efficiency and stability. The commutator segment, as a key component of the commutator, needs to be formed and processed to meet the requirements of conductivity and insulation.

[0003] In a Chinese patent with publication number CN215788074U entitled "A Commutator Segment Processing Equipment for a Permanent Magnet DC Torque Motor Commutator", the grooving component is controlled by a control system to groove the commutator segments; the control system then controls the moving component to move the commutator segments to the cutting component; finally, the control system controls the cutting component to cut the commutator segments.

[0004] However, this device still has shortcomings. The above-mentioned equipment adopts a single-station processing mode when working, which means that after processing one commutator segment, it is necessary to stop the machine and manually add a new part to be processed before restarting the machine to continue production. This processing method is prone to interruption of production rhythm, especially in batch production scenarios, where downtime accounts for a large proportion, which seriously reduces processing efficiency and increases production costs. In order to solve the above problems, the inventors proposed a commutator segment forming and processing device for hook-type commutator production. Utility Model Content

[0005] To address the issue of significant downtime caused by the need for manual addition of new parts after processing a single commutator segment in a single-station processing mode, this invention aims to provide a commutator segment forming and processing device for hook-type commutator production.

[0007] Preferably, upright plates are symmetrically fixedly connected to the top of the square plate near both sides, and a lead screw is rotatably connected to the inside of the upright plate, with the side end of the lead screw rotatably connected to the limiting plate. A limiting shaft is fixedly connected to the bottom of the Z-shaped plate near the center of one side.

[0008] Preferably, a groove is provided at the center of the mounting plate, and the limiting shaft is slidably connected to the groove. A gear is rotatably connected at the center of the top of the support, and both racks mesh with the gear.

[0009] Preferably, a motor is provided at the bottom end of the support, and the output end of the motor passes through the support and is fixedly connected to the gear. A motor is provided at the side end of the vertical frame and near the top center, and a milling cutter is fixedly connected to the output end of the motor through the vertical frame.

[0010] Preferably, a drive slide is fixedly connected to one side of the side plate near the support and near the top center, and a motor is provided on one side of the drive slide, with a cutting blade fixedly connected to the output end of the motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] By adopting the above technical solution, the upright plate 52 is provided with a high-precision threaded hole, and the lead screw 54 is threadedly rotatably connected to the threaded hole. One end of the lead screw 54 is provided with a handwheel for easy manual adjustment, and the side end of the lead screw 54 is rotatably connected to the limiting plate 53 through a bearing, which can reduce rotational resistance.

[0023] A limiting shaft 27 is fixedly connected to the bottom end of the Z-shaped plate 26 and near the center of one side.

[0024] By adopting the above technical solution, a U-shaped guide groove is provided on the upper part of the support 2 near both sides, and its limiting shaft 27 is slidably connected to it, so as to facilitate the movement of the Z-shaped plate 26 on the mounting plate 24 through the limiting shaft 27.

[0025] A groove 25 is provided at the center of the mounting plate 24, and the limiting shaft 27 is slidably connected to the groove 25.

[0026] By adopting the above technical solution, the mounting plate 24 has a groove 25 inside, which is to facilitate the sliding of the limiting shaft 27.

[0027] A gear 21 is rotatably connected at the center of the top of the support 2, and both racks 23 mesh with the gear 21.

[0028] By adopting the above technical solution, the rotating gear 21 is set so as to drive the two racks 23 to move horizontally at the same time.

[0029] A motor 22 is installed at the bottom of the support 2, and the output end of the motor 22 passes through the support 2 and is fixedly connected to the gear 21.

[0030] By adopting the above technical solution, the working motor 22 is started, thereby causing the fixedly connected gear 21 to rotate.

[0031] A motor 31 is installed on the side of the vertical frame 3 and near the top center. The output end of the motor 31 passes through the vertical frame 3 and is fixedly connected to a milling cutter 32.

[0032] By adopting the above technical solution, the center of the milling cutter 32 and the center of the limiting plate 53 are at the same level, and the milling cutter 32 can be a carbide end mill 32 with a blunting treatment on the cutting edge to improve its service life.

[0033] A drive slide 41 is fixedly connected to one side end of the side plate 4 near the support 2 and near the top center. A motor 42 is provided on the side end of the drive slide 41, and a cutter blade 43 is fixedly connected to the output end of the motor 42.

[0034] By adopting the above technical solution, the cutting blade 43 and the center of the limiting plate 53 are at the same level, which facilitates the cutting of the commutator segment.

[0035] Working principle: During operation, the commutator segment is first placed between two limiting plates 53, and rubber pads can be set at the opposite ends of the limiting plates 53 to protect the commutator segment and prevent shaking during processing. Then, the two lead screws 54 are rotated, causing the two limiting plates 53 to move towards each other to complete the clamping and limiting work of the commutator segment. Then, the motor 22 is started, which causes the fixedly connected gear 21 to rotate. Then, the two meshing racks 23 will move towards each other (the two racks 23 are symmetrically distributed). At this time, one of the commutator segments will move towards the vertical frame 3 and the side plate 4 under the action of the Z-shaped plate 26. After moving to the required position, the second drive slide 5, the first motor 31, the first drive slide 41 and the second motor 42 can be started at the same time. The first motor 31 can drive the milling cutter 32 to slot the commutator segment, and the second motor 42 can drive the cutting blade 43 to cut and divide the slotted commutator segment.

[0036] When one commutator segment is being processed, the operator can place the other commutator segment between another set of limit plates 53 (for the next one to be cut). After one commutator segment is cut, the reverse working motor 22 is activated, so that another rack 23 drives the other commutator segment to move to the slotting section. This avoids the need to stop the machine to add commutator segments during processing, thus ensuring the continuity of processing.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
