Description

Technical Field

[0001] The utility model relates to the technical field of DC motors, in particular to a DC motor commutator slotting machine. Background Art

[0002] A DC motor is a type of electric machine that converts direct current (DC) electrical energy into mechanical energy. When operating as a motor, it converts electrical energy into mechanical energy; when operating as a generator, it converts mechanical energy into electrical energy. In a DC motor, a commutator, working in conjunction with brushes, converts an applied DC power source into alternating current in the armature coils, maintaining a constant direction of electromagnetic torque. The commutator is a cylindrical structure composed of numerous commutator segments, insulated with mica sheets.

[0003] During the processing of DC motor commutators, slots need to be cut using a slotting machine. However, during slotting, the waste chips generated will scatter everywhere, contaminating the table surface and making it inconvenient to clean them centrally. In addition, the waste chips will remain in the slots of the commutator and need to be cleaned again later, which increases the number of steps and affects the processing efficiency. Therefore, improvement is urgently needed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-4 The utility model provides an embodiment: a DC motor commutator slotting machine, including a platform 1, and also includes

[0028] The chip box 12 is installed on one side of the top of the frame 4. The chip box 12 is connected to the output end of the induced draft fan 11 at the top of the frame 4. A chip storage drawer 1201 is provided inside the chip box 12, and a filter screen 1202 is installed inside the chip box 12 on one side of the chip storage drawer 1201. An air outlet 1203 is provided on the outer wall of one side of the chip box 12.

[0029] Grooving knife 10, which is installed at the output end of the third motor 21 below the frame 4;

[0030] Specifically, the third motor 21 drives the slotting knife 10 to rotate, and the first cylinder 9 drives the slotting knife 10 to move downward. At the same time, the first motor 6 drives the transverse screw 7 to rotate, so that the movable seat 8 drives the slotting knife 10 to move horizontally to one side, and the slotting knife 10 slots the commutator. During the slotting process, the stepping motor 17 drives the commutator to rotate through the second clamping block 16, and then controls the slotting knife 10 to move horizontally. In this reciprocating process, the commutator can be continuously slotted, which is efficient and the slot distribution is uniform.

[0031] A suction head 23 is mounted on one end of the chip collecting pipe 22 at the bottom end of the third motor 21;

[0032] Specifically, during the slot drawing process, the induced draft fan 11 operates so that the chip collection pipe 22 sucks the generated waste chips into the chip collection box 12 through the suction head 23. The waste chips are intercepted by the filter screen 1202 and collected in the chip storage drawer 1201. The waste chips can be cleaned by pulling out the chip storage drawer 1201, thereby facilitating centralized cleaning of the waste chips. Moreover, the waste chips are sucked away during the slot drawing process to prevent them from remaining in the slot of the commutator, thus saving the subsequent cleaning process.

[0033] A bidirectional screw rod 2 is installed inside the platform 1, and a second motor 14 is installed on one side of the platform 1. The output end of the second motor 14 is fixedly connected to the bidirectional screw rod 2, and the outer walls on both sides of the bidirectional screw rod 2 are threadedly sleeved with sliders 3;

[0034] The top of the platform 1 is provided with a first clamping arm 5 and a second clamping arm 13 respectively. The bottom ends of the first clamping arm 5 and the second clamping arm 13 both extend into the interior of the platform 1 and are fixedly connected to the slider 3.

[0035] A first clamping block 15 and a second clamping block 16 are respectively mounted on the outer walls of one side of the first clamping arm 5 and the second clamping arm 13, and a rubber friction sheet 18 is adhered to the surfaces of the first clamping block 15 and the second clamping block 16;

[0036] A stepper motor 17 is mounted on the outer wall of the other side of the second clamping arm 13, and the output end of the stepper motor 17 is fixedly connected to the second clamping block 16;

[0037] A second cylinder 19 is installed on the top of the platform 1 between the first clamping arm 5 and the second clamping arm 13, and an arc-shaped supporting plate 20 is installed on the output end of the second cylinder 19;

[0038] The bottom end of the movable seat 8 is mounted with a first cylinder 9, the output end of the first cylinder 9 extends to the bottom of the frame 4 and is fixedly connected to the third motor 21;

[0039] Specifically, the DC motor commutator is placed between the first clamping arm 5 and the second clamping arm 13, and the second motor 14 drives the bidirectional screw 2 to rotate, so that the slider 3 drives the first clamping arm 5 and the second clamping arm 13 to move horizontally toward the commutator from both sides. The first clamping arm 5 and the second clamping arm 13 clamp the commutator through the first clamping block 15 and the second clamping block 16 respectively. The rubber friction plate 18 increases the friction between the first clamping block 15, the second clamping block 16 and the commutator, making the clamping firm and reliable, thereby facilitating the fixation of the commutator. The second cylinder 19 drives the arc support plate 20 to move upward, and the arc support plate 20 supports the commutator from the bottom, thereby improving the stability of the commutator during grooving.

[0040] When the embodiment of the present application is in use: first, the DC motor commutator is placed between the first clamping arm 5 and the second clamping arm 13, and the second motor 14 drives the bidirectional screw rod 2 to rotate, so that the slider 3 drives the first clamping arm 5 and the second clamping arm 13 to move horizontally toward the commutator from both sides, and the first clamping arm 5 and the second clamping arm 13 respectively clamp the commutator through the first clamping block 15 and the second clamping block 16, and the rubber friction plate 18 increases the friction between the first clamping block 15, the second clamping block 16 and the commutator, so that the clamping is firm and reliable, thereby facilitating the fixing of the commutator, and the second cylinder 19 drives the arc support plate 20 to move upward, and the arc support plate 20 supports the commutator from below, thereby improving the stability of the commutator during grooving, and then, the third motor 21 drives the grooving knife 10 to rotate, and the first cylinder 9 drives the grooving knife 10 to move downward, and the third motor 21 drives the grooving knife 10 to rotate. At the same time, the first motor 6 drives the transverse screw rod 7 to rotate, so that the movable seat 8 drives the grooving knife 10 to move horizontally to one side, and the grooving knife 10 grooves the commutator. During the grooving process, the stepping motor 17 drives the commutator to rotate through the second clamping block 16, and then controls the grooving knife 10 to move horizontally. In this way, the commutator can be grooved continuously, with high efficiency and uniform groove distribution. During the grooving process, the induced draft fan 11 runs so that the chip collection suction pipe 22 sucks the generated waste chips into the chip collection box 12 through the suction head 23. The waste chips are intercepted by the filter 1202 and collected in the chip storage drawer 1201. The chip storage drawer 1201 can be pulled out to clean the waste chips, thereby facilitating the centralized cleaning of the waste chips. Moreover, the waste chips are sucked away during grooving to prevent them from remaining in the groove of the commutator, saving the subsequent cleaning process.

[0041] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
