The driving bevel gear ring run-out detector is characterized in that two mutually-symmetrical columns are fixedly arranged on the base, a beam is fixed at the upper ends of the two columns, fixing bolts are symmetrically arranged in the upper parts of the two columns, inner side ends of the two fixing bolts abut against the middle part of a measuring arm, a spherical measuring head is fixed at the front end of the measuring arm through a positioning screw, the spherical measuring head is located above the positioning sleeve, the dial indicator is fixedly arranged on the beam, and the tip of the dial indicator abuts against the rear end part of the measuring arm. The driving bevel gear ring run-out detector is simple in structure and convenient to use, the location benchmark of gear milling processing is used as a detection positioning benchmark, the detection cannot be affected by the center hole, mass detection on run-out of a large batch of driving bevel gear rings of the same variety can be completed, and the accuracy and the repetitive positioning precision are high.

Description

Drive bevel gear tooth runout detector

Technical field

The utility model relates to a kind of drive bevel gear gear ring pick-up unit, specifically a kind of drive bevel gear tooth runout detector.

Background technology

At present, deflection instrument and dial gauge are mainly used in the check of drive bevel gear tooth runout, use first the center pit of the top top workpiece of deflection instrument, workpiece is rotated freely along center pit, measure again the tooth runout of drive bevel gear with dial gauge, the weak point of this cubing is: the clamping difficulty, checkability is low, and uses the center pit Accuracy.

Summary of the invention

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and take the positioning datum of Gear Milling as the check positioning datum, the not impact in acceptor center hole can improve the drive bevel gear tooth runout detector of accuracy of detection.

For reaching above purpose, technical scheme that the utility model adopts is: this drive bevel gear tooth runout detector, comprise base, dial gauge, bearing and locating sleeve, bearing is fixed on the base, locating sleeve is fixed on the bearing, it is characterized in that: be fixed with two symmetrical columns at base, the upper end of two columns is entablature fixedly, top at two columns is arranged with set bolt, the medial extremity of two set bolts withstands on the middle part of gage beam simultaneously, spheric probe on the front end of gage beam is fixing by positioning screw, spheric probe is positioned at the top of locating sleeve, be fixed with dial gauge at crossbeam, dial gauge top withstands on the rearward end of gage beam.

Intentionally effect of the present utility model is: simple in structure, easy to use, take the positioning datum of Gear Milling as the check positioning datum, the not impact in acceptor center hole can be finished in enormous quantities the batch detection with kind drive bevel gear tooth runout, accuracy rate is high, and repetitive positioning accuracy is high.
