A spiral tooth compression jig

Abstract

The utility model discloses a kind of spiral tooth compression jigs, including jig base, the inside of the jig base is provided with the placement groove for placing spiral tooth, one compression groove is respectively arranged at the both sides of the placement groove, and the both sides of the compression groove are placed with the self-adjusting compression block that can rotate correspondingly, the distance between the both sides self-adjusting compression block is set, when spiral tooth is placed in placement groove, the tooth portion of the both sides of spiral tooth is correspondingly pressed on self-adjusting compression block;And the both sides self-adjusting compression block are rotated after corresponding according to the inclination angle of tooth portion, and the upper end surface position is self-adjusted, so that tooth portion end surface and the upper end surface of self-adjusting compression block realize face-to-face contact.The device can realize the tooth portion of spiral tooth and the face of self-adjusting compression block and face contact when specific compression, avoid the point and face contact of tooth portion, so that spiral tooth is evenly stressed in the process of compression, test result is more accurate, more efficient, effectively measure the compression resistance of spiral tooth.
