Description

Fool-proof jig for carbon brush installation direction

Technical Field

The utility model belongs to the technical field of carbon brush installation jigs, and particularly relates to a fool-proof jig for a carbon brush installation direction.

Background

The automobile generator regulator is electrified through the slow contact of the carbon brush and the generator rotor, so that the voltage, the current, the rotating speed and the like of the generator are detected and regulated. As shown in fig. 1, the shape of the carbon brush is that the direction of the inclined head is arranged, if the direction of the carbon brush of the adjuster is reversed, the carbon brush is in poor contact with the slip ring, the abrasion speed of the carbon brush is accelerated, the service life of the adjuster is shortened, or strong noise is generated.

The existing installation method of the carbon brush of the regulator of the automobile generator is that springs are arranged behind the carbon brush of the regulator and abut against the carbon brush, the springs are in a compressed state when the carbon brush is assembled and are only used for fixing products and controlling the extending length of the carbon brush, the carbon brush cannot be effectively and timely found when the assembling direction of the carbon brush is wrong, and the existing method for controlling the direction of the carbon brush mainly depends on visual inspection or electronic inspection equipment of personnel. Personnel visual inspection inefficiency, unreliable, it is very easy because personnel neglect to cause the hourglass to examine to make the defective products flow out, need examine once more after the equipment and increase the process, extravagant man-hour. The electronic inspection equipment additionally increases the purchase, use and maintenance cost of the equipment, and is not in accordance with the development concept of energy conservation and environmental protection. Therefore, the fool-proof fixture for the carbon brush installation direction is designed.

Disclosure of Invention

The utility model aims to provide a fool-proof jig for the carbon brush installation direction, so as to achieve the purposes of accurate detection result, simple structure, energy conservation and environmental protection.
