[0002] The commutator is an important component on the armature of a DC motor and an AC commutator motor. The carbon base body of the carbon commutator has excellent chemical stability and is not easily corroded by alcohols. The carbon commutator is composed of multiple carbon sheets wound into a circle and fixed on a circular commutator shell. If the surface roughness of the carbon sheet is too high, powder scraping will occur during use. If the concentration of carbon powder in the commutator chamber is too high, it will cause a ring fire failure. Therefore, it is necessary to grind and polish the surface of the carbon sheet at the end of the carbon commutator. The carbon commutator grinding device in the prior art cannot be applied to the processing of assembly line equipment, and there are problems such as low grinding efficiency and complicated procedures. In addition, the commutator cannot be effectively positioned during grinding, which makes it easy to shift, thereby affecting the grinding quality of the carbon commutator. Utility Model Content

[0019] like Figure 1-3 As shown, this embodiment provides a carbon commutator grinding tool, which is arranged on one side of the loading turntable 1. The grinding work includes a bracket 3, a positioning seat 2, a clamping arm 5, a clamping drive assembly and a grinding mechanism. There are several positioning seats 2 and they are evenly arranged on the loading turntable 1 along the circumferential direction to position the carbon commutator 12. A positioning column 22 is arranged in the center of the positioning seat 2. The top of the positioning column 22 is not higher than the top of the carbon commutator, and clamping openings 21 are opened on both sides of the positioning seat 2. A mounting plate 31 is transversely provided at the upper end of the bracket 3, a sliding seat 4 is provided at the bottom of the mounting plate 31, a sliding groove 41 is transversely provided at the bottom of the sliding seat 4, the upper ends of two clamping arms 5 are slidably provided in the sliding groove 41, and clamping blocks 51 are provided at the lower ends of the two clamping arms 5. The two clamping blocks 51 are respectively located on both sides of the positioning seat 2 and correspond to the positions of the clamping opening 21 respectively. V-shaped clamping grooves 52 are provided on adjacent sides of the two clamping blocks 51, and anti-slip pads 53 are provided in the clamping grooves 52; the upper ends of the two clamping arms 5 are driven by the clamping drive assembly, so as to move toward the center of the positioning seat 2 and pass through the clamping opening 21 through the clamping blocks 51 to clamp and fix the two sides of the carbon commutator.

[0020] The grinding mechanism includes a driving motor 6, a driving cylinder 7, a lifting plate 8 and a grinding wheel 9. The lifting plate 8 is located below the mounting plate 31 and is driven to rise and fall by the driving cylinder 7 arranged on the mounting plate 31. Guide rods 81 are longitudinally arranged on both sides of the top of the lifting plate 8. The upper ends of the guide rods 81 penetrate the mounting plate 31 and are slidably connected thereto. A grinding wheel 9 is rotatably arranged on one side of the bottom of the lifting plate 8. The grinding wheel 9 is driven to rotate by the driving motor 6 arranged on the lifting plate 8. The grinding wheel 9 is located above the positioning seat 2, and the grinding wheel 9 is not concentric with the positioning seat 2. The edge of the grinding wheel 9 is used to grind the end face of the carbon commutator to ensure the grinding effect.

[0021] In this embodiment, the clamping drive assembly includes a servo motor 10 and a screw rod 11. The screw rod 11 is horizontally arranged in the slide groove 41, and the two ends of the screw rod 11 are horizontally rotatably connected to the two ends of the slide groove 41 through bearings. One end of the screw rod 11 is driven to rotate by the servo motor 10 arranged on the bracket 3. The thread directions of the left and right ends of the screw rod 11 are arranged in opposite directions. The left and right ends of the screw rod 11 are respectively threadedly connected to the upper end of the clamping arm 5. The screw rod 11 is driven to rotate by the servo motor 10, so that the two clamping arms 5 can be displaced toward the center or to both sides at the same time.

[0022] In this embodiment, a rotating shaft 91 is provided at the center of the grinding wheel 9, and the upper end of the rotating shaft 91 is rotatably set at the bottom of one side of the lifting plate 8 through a rotating seat 92, and a driven wheel 93 is provided on the rotating shaft 91; the driving motor 6 is set at the top of the other side of the lifting plate 8, and a driving wheel 61 is provided on the output shaft of the driving motor 6. The driving wheel 61 and the driven wheel 93 are connected by a transmission belt 62, so that the driving motor 6 drives the grinding wheel 9 to rotate.

[0023] When the loading turntable 1 rotates, it drives the positioning seat 2 to move to the grinding tooling and then stops. At this time, the position of the positioning seat 2 is located between the two clamping arms 5, and the position of the clamping mouth 21 is opposite to the clamping block 51. Then, the clamping drive assembly drives the clamping block 51 to clamp and fix the carbon commutator. Then, the servo motor 10 drives the grinding wheel 9 to rotate, and at the same time drives the cylinder 7 to drive the lifting plate 8 to descend, so that the grinding wheel 9 is pressed against the surface of the commutator, thereby performing the grinding operation.
