Cone angle measuring instrument of diaphragm spring

Abstract

The invention discloses a cone angle measuring instrument of a diaphragm spring. The measuring instrument can improve measuring accuracy and is convenient in use, and comprises a flat plate and a dial gauge assembly; the flat plate is provided with a ruler stop, a guide ruler which is perpendicular to the ruler stop, and a movable reference block; and the dial gauge assembly comprises a gauge stand for fixing, the gauge stand is provided with a telescopic arm, and a front end of the telescopic arm is provided with a dial gauge.

Description

technical field [0001] The invention relates to a measuring tool, in particular to a measuring tool for measuring the cone angle of a diaphragm spring in an automobile clutch. Background technique [0002] Existingly used for diaphragm spring angle measurement is the standard measuring tool universal angle ruler produced by the measuring tool factory. Its shortcomings are: 1. When the universal angle ruler measures the first taper, the line length of the first taper of the diaphragm spring is too short, and the second taper It will cause interference to the measurement; 2. The resolution of the universal angle ruler is 2', and the measurement accuracy is not high. 3. The second cone angle measured by the universal angle ruler must be based on the first cone angle, and the angle value relative to the reference plane cannot be directly obtained. 4. Measure the second cone based on the first taper. The second taper is short, and the convex arc interference at the end of the di...

[0002] Existingly used for diaphragm spring angle measurement is the standard measuring tool universal angle ruler produced by the measuring tool factory. Its shortcomings are: 1. When the universal angle ruler measures the first taper, the line length of the first taper of the diaphragm spring is too short, and the second taper It will cause interference to the measurement; 2. The resolution of the universal angle ruler is 2', and the measurement accuracy is not high

3. The second cone angle measured by the universal angle ruler must be based on the first cone angle, and the angle value relative to the reference plane cannot be directly obtained

4. Measure the second cone on the basis of the first taper. The second taper is short, and there is a raised arc interference at the separation finger end of the diaphragm spring, which cannot be measured.
