Carbon brush end face radian grinding device

Abstract

The invention discloses a carbon brush end face radian grinding device. According to the grinding device, the diameter of a ground circumferential face can be freely adjusted through a shear fork structure formed by matching of a first hinged rod and a second hinged rod, so that the ground radian is adjusted, the requirements on generator rotor slip rings of different specifications are met, and meanwhile powder generated during grinding can be collected through a base. The grinding device is characterized in that a supporting plate is arranged on the base, a guide sleeve is arranged on one side of the supporting plate, a sliding rod is arranged in the guide sleeve, a limiting block is arranged at one end of the sliding rod, the other end of the sliding rod is bent towards the base, a fixed plate is arranged at the other end of the sliding rod, a graduated scale is arranged at the top of the supporting plate, and baffles are arranged on the periphery of the base and extend up obliquely towards the outer side of the base.

AI Technical Summary

Problems solved by technology

[0002] A carbon brush is a device that transmits energy or signals between the fixed part and the rotating part of a motor or generator or other rotating machinery. When a carbon brush is used on a generator, it needs to be in contact with the generator rotor slip ring. Since the slip ring is a cylinder , and the end of the brand-new carbon brush is generally flat. In order to make the carbon brush and the slip ring fully contact, it is necessary to grind the end of the carbon brush before installing the carbon brush, so that the carbon brush can be ground to match the radian of the slip ring. However, for new employees or people with bad business, it is often easy to grind in place when replacing the grinding carbon brush, and the manual grinding efficiency is low, while the existing electric rotating grinding drum is used for grinding. The radius is fixed, resulting in a fixed grinding radian, which cannot meet the grinding requirements of generator rotor slip rings of different specifications

[0003] Notification number CN206643733U discloses a generator carbon brush grinding device, including a support frame, a carbon brush fixing frame, a handle and a roller, the roller is lying on the side and connected to the support frame through bearings, the carbon brush fixing frame is fixedly connected with the support frame, and the carbon brush The fixing frame is cylindrical and is set outside the roller. The side wall of the carbon brush fixing frame is provided with a carbon brush fixing strip. The carbon brush is fixed on the inner side of the carbon brush fixing strip. The side wall of the roller is covered with sandpaper. In contrast, the carbon brush fixing frame and the roller are coaxial, and the handle is fixedly installed on the end surface of the roller. The grinding arc of the grinding device is fixed when grinding. When grinding carbon brushes for different sizes of generator rotor slip rings, the specifications of the grinding roller need to be replaced repeatedly. , more inconvenient

[0004] The notification number CN211277837U discloses a generator carbon brush grinding tool, one side of the third support frame and one side of the first support frame are fixedly connected to the outer ring of the first bearing, and the two sides of the second support frame Both sides are fixedly connected to the outer ring of the second bearing, and the inner ring of the first bearing and the second bearing is fixedly connected to a rotating shaft. The grinding arc of this device is fixed, which cannot meet the grinding requirements of generator rotor slip rings with different radii.
