Description

Technical Field

[0001] The utility model mainly relates to the field of conductive slip ring grinding, in particular to a generator slip ring end face grinding device. Background Art

[0002] Motor slip rings, also called collector rings or conductive rings, are used to cooperate with commutators to achieve mechanical commutation, that is, to ensure that the power input to a DC motor or output by a DC generator is DC power. The contact between the brushes of a running generator and the slip rings will cause uneven currents flowing through each brush, resulting in some brushes having zero current and others having large currents. Long-term operation will cause wear and dents on the contact end faces, which will cause uneven currents flowing through each brush, resulting in some brushes having zero currents.

[0003] In addition to replacing new carbon brushes, the generator slip ring end face also needs to be ground. The grinding is generally done manually. Most of the existing slip ring end face grinding devices grind the slip ring end face by wrapping sandpaper on the slip ring end face and rotating the slip ring end face. The diameter of the ground end face cannot be adjusted during use. Utility Model Content

[0019] like Figure 1-3 As shown, the generator slip ring end face grinding device described in the utility model comprises a frame 1, which is the main component for installing various components of the device. A rotating mounting frame 11 is welded to the rear side of the frame 1, and a rotating motor 2 is bolted to the rotating mounting frame 11. A sleeve 3 is installed on the rotating shaft of the rotating motor 2, and the sleeve 3 is used to sleeve the slip ring. After the slip ring is sleeved on the sleeve 3, the slip ring is driven to rotate by the rotating motor 2, so that the overall uniform grinding is completed by using the grinding device.

[0020] A grinding mounting frame 4 is welded to the front side of the frame body 1 and is located outside the front side of the rotating mounting frame 11 , so that the grinding mounting frame 4 is not parallel to the rotating mounting frame 11 , providing operating space for the grinding of the grinding device.

[0021] A plane displacement mechanism 5 is arranged on the grinding mounting frame 4, a grinding frame 6 is arranged on the plane displacement mechanism 5, and an angle-adjustable grinder 7 is arranged on the grinding frame 6.

Specifically, in the present embodiment, there are four support rods 41, and the bottoms of the four support rods 41 are welded by connecting rods to complete the fixation of the support rods 41. A support plate 42 is slidably arranged on the support rods 41, and the support plate 42 is fixed at the threaded end by nuts, and the plane displacement mechanism 5 is arranged above the support plate 42.

[0024] Further, an articulated seat 43 is arranged on the top of the grinding mounting frame 4, and the grinder 7 is fastened and connected to the articulated seat 43 by bolts. By loosening the bolts, the angle of the grinder 7 can be adjusted, and the grinder 7 and the grinding mounting frame 4 can be fixed after the bolts are fastened.
