Description
Technical field
The utility model relates to jig detection field, in particular to a kind of novel Pore Diameter Detection jig, inside diameter measurement height
Rule.
Background technique
In field of machining, the pore size control of workpiece is very important, in order to preferably control the aperture of workpiece,
It is generally measured using go-no go gauge, each aperture needs to measure twice, i.e., drift is primary, no-go gage is primary, just may know that aperture
It is whether qualified, it may be influenced less for inspecting measurement by random samples in proportion, but the product for needing to measure totally, side needs a large amount of
Time with manually measure.
Summary of the invention
The purpose of the utility model is to provide it is a kind of it is novel using high metric into the jig for carrying out Pore Diameter Detection and its quickly
Detection method, to solve the problems in background technique.
To achieve the goals above, the utility model provides the following technical solutions:
A kind of novel Pore Diameter Detection jig, measuring block and fixed block including integral structure, the measuring block and fixed block
For identical axle center, the measuring block is taper, and bottom is zero point, and the fixed block is equipped with axle center identical as measuring block
Mounting hole.
Further technical solution, the fixed block are equipped with the fixed screw vertical with mounting hole, the fixed screw
It is screwed on fixed block and may extend into the mounting hole.
A kind of high metric of inside diameter measurement uses Pore Diameter Detection jig.
A kind of bore diameter measuring method, including high metric is used, the high metric is equipped with the probe of vertical process, the height
The probe up and down motion of metric measures, comprising the following steps:
S1, probe is put into mounting hole, fixed block and probe is fixed using fixed screw；
S2, the workpiece measured will be needed to be placed on test desk, the measured hole on workpiece is to be vertically arranged, most by measuring block
The zero point of lower section touches the upper surface of workpiece, is at this time 0 by the degree setting of high metric.
S3, by the measured hole center of workpiece and measuring block it is same axle center, moves down measuring block, make cone and measured hole
Contact point is formed when contact, is stopped movement, is read the distance b moved down.
S4, according to distance b, the actual achievement data of the diameter a of measured hole can be calculated, judge whether qualification.
Further technical solution, in the S1 step, probe, fixed block and the same axle center setting of measuring block.
Further technical solution, in the S3 step, the data b that measuring block is moved down since 0 is less than or equal to survey
The depth of metering-orifice.
Further technical solution, S1 the and S2 step are only limited to use when measurement unit one.
The utility model has the following beneficial effects:
It drives the cone of measuring block to move down using high metric, the aperture number that measurement obtains is calculated by trigonometric function
Value, it is primary to can determine whether aperture is qualified, and measurement efficiency greatly improves.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the measuring principle schematic diagram of the utility model.
Specific embodiment
The utility model is further described below in conjunction with attached drawing:
As shown in Figure 1 and 2, a kind of novel Pore Diameter Detection jig, measuring block 1 and fixed block 2 including integral structure are described
Measuring block 1 is identical axle center with fixed block 2, and the measuring block 1 is cone 11, and bottom is 0. 12, on the fixed block 2
Mounting hole 21 equipped with axle center identical as measuring block 1.
Further technical solution, the fixed block 2 are equipped with the fixed screw 22 vertical with mounting hole 21, the fixation
Screw 22 is screwed on fixed block 2 and may extend into the mounting hole 21.
A kind of high metric of inside diameter measurement uses Pore Diameter Detection jig.
A kind of bore diameter measuring method, including high metric is used, the high metric is equipped with the probe of vertical process, the height
The probe up and down motion of metric measures, comprising the following steps:
S1, probe is put into mounting hole 21, fixed block 2 is fixed with probe using fixed screw 22；
S2, the workpiece 3 measured will be needed to be placed on test desk, the measured hole 31 on workpiece 3 is to be vertically arranged, and will be measured
The 0. 12 of 1 bottom of block touch the upper surface of workpiece 3, are at this time 0 by the degree setting of high metric.
S3, by 31 center of measured hole of workpiece 3 and measuring block 1 it is same axle center, moves down measuring block 1, make cone 11
Contact point 13 is formed when contacting with measured hole 31, is stopped movement, is read the distance b moved down.
S4, according to distance b, the actual achievement data of the diameter a of measured hole 31 can be calculated, judge whether qualification.When reading b
Data when, 1 axle center of measuring block and contact point 13 form the first right-angle side a1, b and form the second right-angle side, and 11 edge of cone is formed
Bevel edge 14, to form a right angled triangle, it is known that the actual achievement data of the angle r and b of bevel edge 14 and b, according to trigonometric function
The data of a1 can be calculated, and the diameter of measured hole 31 is a=2a1, so that the data of the diameter a of measured hole 31 are calculated,
In actual measurement, measured hole 31 is qualification in a certain range, such as a ± 0.1mm, can also be obtained by calculation in height
Data area on rule is to reach the range of a ± 0.1mm.
Further technical solution, in the S1 step, probe, fixed block 2 and the setting of the same axle center of measuring block 1.
Further technical solution, in the S3 step, the data b that measuring block 1 is moved down since 0 is less than or equal to survey
The depth of metering-orifice 31.
Further technical solution, S1 the and S2 step are only limited to use when measurement unit one 3, from measurement second
A workpiece 3 starts, it is only necessary to use S3 and S4 step.
The above not the technical scope of the utility model is imposed any restrictions, it is all according to the utility model technical spirit to
On embodiment made by any modification, equivalent variations and modification, in the range of the technical solution for still falling within the utility model.
