Embodiment 1

[0032] A kind of V-shape measurement method of outer diameter involved in embodiment 1 of the present invention, the measurement principle of its zero parameter deviation is as follows figure 1 As shown, the sine value of the half angle α of the V-shaped angle is equal to 1 / 3, that is, sin α=1 / 3, α=arcsin(1 / 3). The outer diameter of the tested part is placed in the V-shaped corner and is tangent to both sides of the V-shaped corner;

[0033] The contact point between the measuring rod of the measuring sensor and the measured shaft (that is, the measurement position) is on the angle bisector of the V-shaped angle, which is the distance between the line segment formed by the vertex of the V-shaped angle and the center of the measured shaft and the outer diameter of the measured shaft. intersection.

[0034] When the two diameters are φ 0 , φ 1 When the axis of the sensor is put into the V-shaped angle successively for measurement, the displacement of the sensor rod △y is the ...

Embodiment 2

[0056] The V-shaped checking tool for the outer diameter of the valve disc part involved in the present invention is a checking tool for comparatively measuring the outer diameter of the valve disc part of an automobile engine by using the detection method described in Embodiment 1. figure 2 It is a schematic diagram of the outer diameter of the engine valve disc. The outer diameter of the valve disc of different types of automobile engines is about φ22mm to φ55mm, and the diameter deviation is usually ±0.1mm.

[0057] Because there are deviations in the processing, assembly, and measurement of the inspection tools and standard parts for comparison, such as the measurement error of the diameter of the standard part, the deviation of the V-shaped half-angle α from the theoretical value arcsin (1 / 3), and the measuring rod is not at the V-shaped angle. There are deviations such as eccentricity and inclination on the bisector, and there are deviations relative to the theoretical d...

Abstract

The invention provides an outer diameter V-shaped measurement method. The method includes the following steps that: a V-shaped gauge for detecting outer diameter is provided, wherein the V-shaped gauge is provide with a V-shaped corner of which the angle value is 2*alpha, wherein the value of alpha is arcsin (1 / 3); the V-shaped gauge also comprises a sensor, and when a standard shaft is arranged into the V-shaped corner and is tangent to two sides of the V-shaped corner, and numerical value presetting is performed on the sensor; and after a measured shaft is arranged in the V-shaped corner and is tangent to the two sides of the V-shaped corner, the sensor measures the displacement of a measuring point, and the displacement of the measuring point is the difference of the outer diameter of the standard shaft and the outer diameter of the measured shaft, and the measuring point is an intersection point of a line segment formed the vertex of the V-shaped corner and the center of the measured shaft, and the outer diameter of the measured shaft, and the measuring rod of the sensor and the measuring point of the measured shaft are located at the angular bisector of the V-shaped corner. Correspondingly, the invention also provides an outer diameter V-shaped measurement method-based V-shaped gauge of valve retainer outer diameter. With the outer diameter V-shaped measurement method and the V-shaped gauge of the valve retainer outer diameter of the invention adopted, problems of high operation difficulty and low measurement efficiency in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of detecting the outer diameter of parts, in particular to a V-shaped measuring method for the outer diameter and a V-shaped inspection tool for the outer diameter of a valve disc. Background technique [0002] For the measurement of the outer diameter of shaft parts, there are generally length measuring instruments, three-coordinate measuring machines, optical measuring instruments, projectors, vernier calipers, outer micrometers, caliper gauges, go-no-go gauges, and special inspection tools. They each have advantages and disadvantages and are suitable for different requirements and environments. In the prior art, vernier calipers, outer micrometers, snap gauges, go-no-go gauges, and 90° V-shaped inspection tools are often used for measurement at the production site, but the limitations of their use are also obvious. [0003] The vernier caliper has a small division interval, and the measurement error caused by alig...
