Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
A kind of cone plunger linearity measurer, combined with Figure 1 and Figure 2, include measuring table 1, dial gauge 2 and length bar 3,
In, 1 upper surface of measuring table is rectangular planes, and support portion 11, the sustainable measurement of support portion 11 are provided on the downside of measuring table 1
Platform 1 simultaneously makes measuring table 1 in ramp shaped, specifically, support portion 11 is in horizontally disposed triangular prism shape, 11 both ends of the surface of support portion
Vertically, and one side horizontal, horizontal side one end of measuring table 1 are intersected with 1 upper surface of measuring table, and the other end, which is located at, to be surveyed
It measures 1 lower section of platform and 11 bottom surface of support portion and 1 upper surface angle of measuring table is acute angle.
Length bar 3 is fixedly installed on 1 upper surface of measuring table, and there are two parallel interval settings, the length direction water of length bar 3
Flat and parallel with 1 upper surface of measuring table, for two length bars 3 for cone of support plunger 5 simultaneously, when measurement, need to keep cone plunger 5
Length direction perpendicular to length bar 3 length direction, in order to measure.
Length bar 3 may be configured as semicylinder, and the plane opposite with 3 cambered surface of length bar is coplanar with platform upper surface on length bar 3, cone
The conical surface 52 of plunger 5 is supported by the cambered surface of length bar 3；Length bar 3 may be alternatively provided as
The parallel plane in face, specifically, setting the one side rectangle strip structure parallel with platform upper surface for length bar 3.
Measuring table 1 offers mounting hole 12 far from 11 one end of support portion, and 12 axis of mounting hole is perpendicular to measuring table 1
Upper surface, dial gauge 2 is perpendicular to 1 upper surface of measuring table and its contact 21 is upward through mounting hole 12 and fixes, the touching of dial gauge 2
