Detector for detecting angular orientation and depth of pinhole of camshaft

Abstract

The invention relates to a detector for detecting angular orientation and depth of a pinhole of a camshaft, comprising a base, a stationary center, a rolling center, an angular orientation locating device and a bolt device used for judging whether the phase angle and depth of a detected pinhole meet the requirement. The stationary center and the rolling center are arranged above the base respectively by a stationary center seat and a rolling center seat and jointly determine the datum axis of the axes of the detected camshaft; the angular orientation locating device comprising a V-shaped angular orientation locating block and the bolt device are arranged on the base between the stationary center and the rolling center; and the V-shaped angular orientation locating block is connected with the base in a sliding-fit manner that the V-shaped angular orientation locating block can move up-and-down in a plane vertical to the datum axis. The invention adopts the V-shaped angular orientation locating block to realize bilateral angular orientation locating and reduce impact on locating precision due to the casting shrink of a standard cam peach. The detector can be operated conveniently and the detection efficiency is high.

Description

technical field [0001] The invention relates to an instrument for judging whether the phase angle and depth of a radial pin hole on a camshaft are qualified or not, and is particularly suitable for the qualification judgment of the above-mentioned items of the cast-formed camshaft of an automobile engine. Background technique [0002] The radial pin hole on the camshaft of the automobile engine is not only used as the angular installation reference when the gear is installed, but also as the angular process reference during the cam grinding process. The accuracy of the phase angle is of great significance. Therefore, the radial pin hole phase angle And the depth is one of the important testing items in the camshaft testing. Objectively, it is necessary to have an easy-to-operate detector that can judge whether the phase angle and depth of the radial pin hole are qualified. [0003] The measurement benchmark of the radial pin hole phase angle is the symmetry center of the dat...

Problems solved by technology

[0003] The measurement benchmark of the radial pin hole phase angle is the symmetry center of the datum cam peach, and some existing detectors adopt single-sided angular positioning, that is, an angular positioning device is set at the peach-shaped side of the datum cam peach , because the positioning surface used in the detection is the rough surface, the consistency of the cam peach shape is poor, so the detection error is large
