Abstract
The invention discloses a method for measuring the depth of a theoretical intersection point of an oblique fillet, which comprises the following steps: step S1, extending the depth micrometer into the work piece with the oblique fillet, keeping the moving rod of the depth micrometer parallel to one side of the work piece with the oblique fillet, and measuring the vertical distance d between the side parallel to the moving rod and the moving rod; step S2, moving a moving rod of the depth micrometer up and down to enable a lower end contact of the moving rod to touch the bottom wall of the workpiece with the inclined fillet, and reading the reading H of the depth micrometer; step S3, measuring the inclination angle A of the bottom wall of the workpiece with the oblique fillet; in step S4, the depth of the theoretical intersection point of the rounded corner can be calculated according to the formula x-d tanA. The depth of the theoretical intersection point of the inclined fillet can be quickly calculated by reading the reading of the depth micrometer at any point of the inclined fillet workpiece, the vertical distance d between the moving rod and the side wall at the moment and the inclination angle A of the bottom wall of the inclined fillet workpiece through a formula x-H-d tan A.
Description
Technical field
The present invention relates to a kind of measurement methods of oblique fillet theoretical intersecting point depth.
Background technique
When engineering calculation, it is often necessary to know the depth of oblique fillet theoretical intersecting point, and the depth is difficult directly to measure, this hair
It is bright that a kind of measurement method of oblique fillet theoretical intersecting point depth is provided, to solve the measurement of the depth of oblique fillet theoretical intersecting point.
Summary of the invention
The technical problem of being solved of the invention is: it is deep to overcome the deficiencies of the prior art and provide a kind of oblique fillet theoretical intersecting point
The measurement method of degree meets the needs of engineering calculation to solve the measurement of oblique fillet theoretical intersecting point depth.
In order to solve the above-mentioned technical problem, the technical scheme is that a kind of measure oblique fillet theoretical intersecting point depth
Method, comprising the following steps:
Micrometric depth gauge is protruded into oblique fillet workpiece and keeps the mobile bar of micrometric depth gauge and oblique fillet workpiece by step S1
One side it is parallel, measure the vertical range d between the one side parallel with mobile bar and mobile bar；
Step S2 moves up and down the mobile bar of micrometric depth gauge, and the lower end contact of mobile bar is made to encounter oblique fillet workpiece
Bottom wall, and read the reading H of micrometric depth gauge at this time；
Step S3 measures the inclination angle A of oblique fillet workpiece bottom wall；
The depth of oblique fillet theoretical intersecting point can be calculated according to formula x=H-d*tanA by step S4.
Further, the vertical range d between the one side and mobile bar parallel with mobile bar, the step are measured for convenience
In S1, be cased with contact ring, contact ring and mobile bar tight fit on the outside of the mobile bar of micrometric depth gauge, i.e., the most inner side of contact ring with
Mobile bar contact, the outermost for contacting ring and the side wall of oblique fillet workpiece is kept in contact, one side parallel with mobile bar and shifting
Vertical range d between lever is the diameter for contacting ring.
After above-mentioned technical proposal, the present invention reads the reading of micrometric depth gauge by any point in oblique fillet workpiece
Number and at this time the vertical range d between mobile bar and side wall, and the tiltedly inclination angle A of fillet workpiece bottom wall, pass through formula x=H-
D*tanA can calculate the depth of oblique fillet theoretical intersecting point quickly；It measures for convenience vertical between mobile bar and side wall
Distance d, the present invention convert the measurement of vertical range d to using the method for the set contact ring in mobile bar the survey of contact ring diameter
Amount, to be further simplified measuring process, makes to measure simpler.
Detailed description of the invention
Fig. 1 is the schematic diagram of measurement method of the invention；
In figure, 1, contact ring, 2, micrometric depth gauge, 3, oblique fillet workpiece.
Specific embodiment
In order that the present invention can be more clearly and readily understood, right below according to specific embodiment and in conjunction with attached drawing
The present invention is described in further detail.
As shown in Figure 1, a kind of method for measuring oblique fillet theoretical intersecting point depth, comprising the following steps:
Micrometric depth gauge 2 is protruded into oblique fillet workpiece 3 and keeps the mobile bar of micrometric depth gauge 2 and oblique fillet by step S1
One side of workpiece 3 is parallel, measures the vertical range d between the one side parallel with mobile bar and mobile bar, i.e. mobile bar and side
The distance between wall is d；
Step S2 moves up and down the mobile bar of micrometric depth gauge 2, and the lower end contact of mobile bar is made to encounter oblique fillet workpiece 3
Bottom wall, and read the reading H of micrometric depth gauge at this time；
Step S3 measures the inclination angle A of oblique 3 bottom wall of fillet workpiece；
The depth of oblique fillet theoretical intersecting point can be calculated according to formula x=H-d*tanA by step S4.
Preferably, as shown in Figure 1, in the step S1, contact ring 1, contact are cased on the outside of the mobile bar of micrometric depth gauge 2
The most inner side of ring 1 and mobile bar tight fit, i.e. contact ring 1 is contacted with mobile bar, by the outermost for contacting ring 1 and oblique fillet workpiece
3 side wall is kept in contact, and the vertical range d between one side parallel with mobile bar and mobile bar is the diameter for contacting ring 1.
The reading and mobile bar and side at this time that the present invention reads micrometric depth gauge 2 by any point in oblique fillet workpiece 3
Vertical range d between wall, and the tiltedly inclination angle A of 3 bottom wall of fillet workpiece, can be quickly by formula x=H-d*tanA
Calculate the depth of oblique fillet theoretical intersecting point；The vertical range d between mobile bar and side wall is measured for convenience, and the present invention uses
The method of set contact ring 1 converts the measurement of vertical range d to the measurement of contact 1 diameter of ring in mobile bar, thus further
Simplify measuring process, makes to measure simpler.
Particular embodiments described above, pair present invention solves the technical problem that, technical scheme and beneficial effects carry out
It is further described, it should be understood that the above is only a specific embodiment of the present invention, is not limited to this
Invention, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in this hair
Within bright protection scope.
