Abstract
The invention discloses a shaft hole end surface checking fixture. The shaft hole end surface checking fixture comprises a base; a datum shaft is arranged on the base; the upper end surface of the datum shaft is taken as a shaft hole datum surface; a shaft to be measured is fixed on the datum shaft; and a positioning shaft is in equal-size matched connection with the shaft to be measured. According to the shaft hole end surface checking fixture, the positioning shaft is in equal-size matched connection with the shaft to be measured; a positioning disc is rotated, so that a probe which contacts with the shaft hole datum surface can rotate with the positioning disc; under the effect of the elastic force of a spring, the probe and the shaft hole datum surface can constantly keep a contact state; if perpendicularity error exists between a shaft hole end surface to be measured and the shaft hole datum surface, the positioning disc moves along the axial direction of the positioning shaft; and the movement range of the positioning disc can be displayed through a dial indicator; a detection range can be wider through moving the probe and the dial indicator, so that detection blind points are fewer; the shaft hole end surface checking fixture can be also used for detecting the end surface runout of a shaft hole. The shaft hole end surface checking fixture has the advantages of small detection error, simple measurement, high detection efficiency and the like.
