Description
Technical Field
[0001] This invention relates to the field of commutator chamfering technology, specifically to a commutator chamfering device. Background Technology
[0002] Commutators are conductive and insulating components on electric motors. Commutators are designed according to requirements, and their structures and names vary. C-shaped commutators are mostly ring structures made of a single copper strip through positioning, cutting, flattening, tearing hooks, and bending. The finished copper parts need to be combined with an insulating core for use. The insulating core is mostly made of hard bakelite or modified thermosetting plastic to fix and support the bent ring copper parts. The utility model disclosed in CN210937490U is a commutator chamfering device, specifically relating to the field of metal processing. It includes a worktable with a mounting base on which multiple scrapers can be mounted simultaneously, greatly improving processing efficiency. The mounting base and slider slide vertically up and down along a sliding rod and side plate, respectively. The sliding rod and side plate act as guides and stabilizers, ensuring stable chamfering straightness and uniformity during operation. This device achieves stable chamfering design by guiding the chamfering tools. Currently, for small electric motor C-shaped commutators, due to their small size, this processing method often results in low efficiency during batch chamfering. Furthermore, the small size of the commutator makes each clamping operation cumbersome and difficult to operate, inconvenient to use, and the debris generated during chamfering is difficult to collect and process.

The side of the operating rod 13 located in the clamping control slot 42 is inserted into the push slot 25, and the upper side of the push slot 25 near the clamping piece 24 is set with an inclined surface. When the operating rod 13 descends, the lower end of the operating rod 13 first inserts into the positioning hole 18 of the movable turntable 7 to position the movable turntable 7, and then the operating rod 13 is inserted into the positioning hole 18 of the movable turntable 7. As the insertion rod 13 continues to descend, it is inserted into the push slot 25 of the push block 20. Under the action of the inclined surface of the push slot 25, the push block 20 and the guide block 21 are pushed and moved towards the commutator 9. Then, the commutator 9 is clamped and fixed. After the commutator 9 is clamped and fixed, the insertion rod 13 continues to descend. At this time, the clamping ring 16 presses down and fixes the outer commutator fins of the commutator 9. The lower end of the center stabilizing rod 17 is inserted into the center of the commutator 9. Together with the two guide blocks 21, the commutator 9 is clamped and fixed in multiple dimensions to ensure the stability of the commutator 9 during subsequent chamfering processing, and the operation is quick and stable.
[0022] A forming assembly is used to chamfer the outer side of the end of the commutator 9 without annular fins. The forming assembly is movably mounted on one side of the upper end of the mounting plate 5. The forming assembly includes a chamfering ring 34 and a lifting movable seat 31. The lifting movable seat 31 is rotatably connected to the chamfering ring 34. The lifting movable seat 31 is connected to the two operating rods 13 through a transmission assembly. The transmission assembly includes a first rack 27, a second rack 33, and a transmission gear 30. The processing table 1 and the mounting plate 5 both have a first rack groove vertically opened at the lower end of the clamping control groove 42. The processing table 1 and the mating base 19 both have a second rack groove on opposite sides. The first rack groove and the second rack groove are correspondingly arranged. A gear groove is opened between the first rack groove and the second rack groove of the processing table 1 and the mating base 19. A first rack 27 is vertically inserted into each of the first rack grooves. A second rack 33 is vertically inserted into each of the second rack grooves. A transmission gear is rotatably installed in each of the gear grooves through a support shaft. The gear 30 has two sides that mesh with one side of the first rack 27 and the second rack 33, respectively. The machining table 1 and the mating base 19 both have transmission grooves 26 located between the clamping control groove 42 and the first rack groove. The upper end of the first rack 27 is inserted into the transmission groove 26 and has a pressing disc. The lower end of the operating rod 13 is inserted into the transmission groove 26 and abuts against the upper end of the pressing disc. A spring groove is provided on one side of the first rack groove, and a vertical spring groove is provided within the spring groove. A spring guide rod is provided, and a guide plate 28 is provided on one side of the first rack 27.

After the commutator 9 is fixed, the operating rod 13 continues to descend. At this time, the movable pressure plate 14, the clamping ring 16 and the central stabilizing rod 17 do not move. The lower end of the operating rod 13 pushes the first rack 27 in the transmission groove 26 to descend, and the first rack 27 drives the transmission gear 30 to rotate.
[0023] The lifting movable seat 31 is located between two second racks 33, which are fixedly connected to both sides of the lifting movable seat 31. Several support guide rods 32 are vertically arranged at the lower end of the lifting movable seat 31, and these rods 32 vertically and movably pass through the mounting pad 5. The lifting movable seat 31 is fitted with a chamfered rotating ring 34 via a sealed bearing. The chamfered rotating ring 34 is located directly below the commutator 9. An annular actuating groove is formed at the center of the lifting movable seat 31 fitted with the chamfered rotating ring 34. Several actuating blades 35 are provided on one side of the annular actuating groove of the chamfered rotating ring 34. The upper end of the device has an inner conical groove 38, and several chamfering blades are inclinedly arranged in the inner conical groove 38. A diversion transition groove 37 is opened in the chamfering ring 34. The diversion transition groove 37 is connected to the annular actuating groove.

Two constraint screws 41 are threadedly inserted on the operation control plate 12. The lower ends of the two constraint screws 41 abut against the upper ends of the movable pressure plate 14. When the first rack 27 descends and the transmission gear 30 rotates, the transmission gear 30 pushes the second rack 33 upward. This causes the lifting movable seat 31, connected to the two second racks 33, to rise along several support guide rods 32, allowing the lower end of the commutator 9 to insert into the inner conical groove 38 of the chamfering ring 34 and contact the chamfering blade. During this process, the air source connector 36 connects to a high-pressure airflow provided by an air compressor. This high-pressure airflow can drive the chamfering ring 34, equipped with actuating blades 35, to rotate at high speed, completing the chamfering operation on the lower end of the commutator 9 during the upward movement of the lifting movable seat 31. The chamfering depth... There is a direct connection between the operating rod 13 and the lowering height. To avoid the control cylinder 11's operating error, two constraint screws 41 are provided on the operating control plate 12. When the lower end of the constraint screw 41 abuts against the upper end of the movable pressure plate 14, the movable pressure plate 14 remains stationary under the support of the clamping ring 16. At this time, the operating control plate 12 cannot continue to descend, and consequently, the lifting movable seat 31 and the chamfering rotating ring 34 cannot continue to rise. In addition, the high-pressure airflow sent into the annular actuating groove by the air source connector 36 can enter several blow-off holes 39 from the diversion transfer groove 37 to blow down the contaminants cut off by the chamfering knife.
[0024] The mounting plate 5 is located at the lower end of the chamfered ring 34 and has a clearance hole. The lower end of the chamfered ring 34 is fixed with a collection filter cylinder 40 by bolts. The collection filter cylinder 40 is coaxially arranged with the chamfered ring 34. The lower end of the collection filter cylinder 40 passes through the clearance hole of the mounting plate 5 and has several separation holes. The metal debris blown downward falls from the center hole of the chamfered ring 34 into the collection filter cylinder 40 for centralized collection and treatment.
