Description
Technical Field
The invention relates to a gauge and a detection method, in particular to a gauge and a detection method for detecting the height of a truncated cone shape on the inner surface of a friction ring.
Background
Friction rings are the most critical component of a transmission synchronizer, and their mass directly determines the performance of the transmission synchronizer and thus the overall transmission.
The friction ring has a structure shown in fig. 1-3, wherein the inner surface of one end of the friction ring is in a truncated cone shape, the bottom surface of the big end of the truncated cone shape is coincided with the end surface of the friction ring, an annular groove is arranged on the inner surface of the friction ring at the adjacent position outside the bottom surface of the small end of the truncated cone shape, one inner side surface of the annular groove is intersected with the side surface of the truncated cone shape, the intersection line is an outer contour circle of the bottom surface of the small end of the truncated cone shape, and the intersection line is 45 degrees with the axis of the friction ring through the intersection line of the plane of the axis of the friction ring and the inner side surface of the annular groove close to one side of the truncated cone shape; the inner surface of the other end of the friction ring is provided with a six-claw structure.
When the friction ring works, the inner surface of the truncated cone shape on the friction ring is required to be matched with an adjacent workpiece well, wherein the height H of the truncated cone shape is a critical dimension, and the friction ring must be tightly controlled in the production and processing process.
Because the annular groove of the friction ring is shallow and narrow and the influence of the six-claw structure is caused, the height H of the truncated cone shape can be interfered and cannot be measured when being measured by a caliper or a height ruler; in the same-row measurement, the profilometer is mostly adopted for measurement, the profilometer measurement is precise, the most specific numerical value can be given, but the following defects are found in the production process when the profilometer is used for measurement:
(1) When the contour meter is used for measuring the height H of the truncated cone shape, on one hand, the end face of the friction ring coplanar with the bottom face of the big end of the truncated cone shape is required to be used as a reference face, so that the tool is required to be used for clamping and positioning; on the other hand, when the measuring needle of the profiler finds the lowest point, adjustment is also needed to ensure that the axis of the truncated cone shape is perpendicular to the reference plane; in addition to other series of operations, the whole measurement process takes too long to realize rapid detection.
(2) The friction ring can deform during heat treatment, the flatness of the end surfaces is poor, and after the two end surfaces are ground flat, the conditions of high side and low side and inconsistent heights of the round table shape of the friction ring can sometimes occur; the contour meter is adopted for measurement, only one point of data can be measured at a time, the omnibearing detection of the height H of the truncated cone shape cannot be carried out, and when the measurement is carried out once, the heights of other places of the truncated cone shape cannot be judged, and the condition that the heights are qualified and unqualified at the same time can occur; because the contour meter is adopted for slow detection, one part is generally detected only once, so that the probability of judging the unqualified part as qualified is high, and the omission ratio is high.
(3) The measuring pin of the profiler is expensive, frequent measurement is easy to wear, periodic replacement is needed, and the detection cost is too high.
