Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, the utility model provides a kind of V-type frame precise angle measuring instrument, comprises angle measurement unit and standard V-type frame 7; Angle measurement unit comprises regulator 2 and frame 3, and regulator 2 upper ends are provided with display gauge head 1, and the lower end is provided with measuring head 4, and regulator 2 and frame 3 are by being threaded; Frame 3 belows are provided with the roller 6 of three equal diameters, and these three rollers 6 are connected with frame 3 by spring 5 respectively: each roller 6 is provided with a pair of spring 5, and an end of this a pair of spring 5 is separately positioned on the center of circle of roller 6 front and back ends; The other end that is positioned at three springs 5 of roller 6 front ends is superimposed and is fixed on frame 3 front ends, and the other end that is positioned at three springs 5 of roller 6 rear ends is superimposed and is fixed on frame 3 rear ends; Corresponding and be positioned on the center line of frame 3 before and after spring 5 point of fixity of frame 3 front ends and spring 5 point of fixity of frame 3 rear ends.Three rollers 6 are between two V-arrangement inclined-planes of standard V-type frame 7.
The process of utilizing the utility model that two V-type bevel angles of V-type frame are measured is:
One, at first utilize 7 pairs of display gauge heads 1 of standard V-type frame to return to zero: at first the angle measurement unit level to be placed on the standard V-type frame 7, three rollers 6 are formed one with the line in its three centers of circle and are fallen the distribution mode of isosceles triangle between two V-arrangement inclined-planes of standard V-type frame 7, two rollers 6 that three rollers 6 and spring 5 between the frame 7 guarantee to be positioned at the left and right sides, top closely paste mutually with a roller 6 that is positioned in the middle of the bottom, and the outside surface of three rollers 6 contacts with two V-arrangement inclined-planes, and two rollers 6 that are positioned at the left and right sides, top contact with frame 3 bottoms.Make the display gauge heads 1, regulator 2 and the measuring head 4 that are connected as a single entity and frame 3 in vertical state by threaded adjustment regulator 2 then, and the upper surface of roller 6 contacts in the middle of making measuring head 4 and being positioned at, and stay certain precompressed amount, and adjust the dial plate of display gauge head 1 at last, make pointer to zero.
Two, utilize angle measurement unit that the angle between two V-type inclined-planes of V-type frame to be measured is measured: at first display gauge head 1, regulator 2 and the measuring head 4 that is connected as a single entity to be taken off from frame 3; Then frame 3 and three rollers 6 are placed on the V-type frame to be measured: three rollers 6 are formed one with the line in its three centers of circle and are fallen the distribution mode of isosceles triangle between two V-arrangement inclined-planes of V-type frame to be measured, two rollers 6 that three rollers 6 and spring 5 between the frame 3 guarantee to be positioned at the left and right sides, top closely paste mutually with a roller 6 that is positioned in the middle of the bottom, and the outside surface of three rollers 6 contacts with two V-arrangement inclined-planes.Because angle between two V-type inclined-planes of V-type frame to be measured and the angle between 7 two V-type inclined-planes of standard V-type frame exist certain difference, and two rollers 6 that are positioned at the left and right sides, top contact with frame 3 bottoms, can produce displacement with respect to the roller in the middle of being positioned at 6 so be positioned at two rollers 6 of the left and right sides, top, drive frame 3 simultaneously and move up or down.Then with the display gauge head 1, regulator 2 and the measuring head 4 that are connected as a single entity by being threaded on the frame 3 on the regulator 2, guarantee that display gauge head 1 and measuring head 4 and frame 3 in vertical state, make measuring head 4 contact with the upper surface that is positioned at centre roller 6 by regulating regulator 2 again; With respect to standard V-type frame 7, measuring head 4 changes with respect to the displacement of frame 3, and at this moment, the reading of display gauge head 1 also changes, the reading on the reading displayed gauge outfit 1.Different according to the V-type face angle of selecting roller 6 diameter and V-type frame to be measured for use, it shows that value distinguishes to some extent, just the display precision difference.
Wherein, the relation principle between the V-type face angle difference of the reading that shows on the display gauge head 1 and V-type frame to be measured and standard V-type frame 7 is:
As shown in Figure 2,2 α are angles of V-type frame two V-type faces, and A, B, C are respectively the centers of circle of three rollers 6, and plane F is frame 3 bottom surfaces.OM, ON are that angle is the V-type frame two V-type faces of 2 α, paste mutually with V-type frame two V-type faces and frame 3 bottom surfaces as long as guarantee the outside surface of three rollers 6 of equal diameters, and three rollers, 6 centers of circle constitute isosceles triangle (Δ ABC).
When angle 2 α owing to processing or other reasons V-type frame two V-type faces change, the perpendicular bisector of Δ ABC
Length will change thereupon, so
Variation and angle 2 α of V-type face be varied to certain functional relation.
If: the V-type face angle of standard V-type frame 7 is 2 α
0, corresponding
=H
0V-type frame V-type face angle to be measured is 2 α, corresponding
=H; The roller diameter is D.
Then: H
0=Dcos α
0
Suppose: H is with H
0Being benchmark, is step change with k, at this moment, and H=H
0+ ki, i are the stepping of display gauge head, i=1,2,3 ...
So: H=Dcos α,
(1)
If get D=50mm, 2 α
0=90 °, k=0.001mm is easy to calculate
Find the solution
, the result is as shown in the table:
So the V-type face angle of V-type frame to be measured whenever reduces 0.194 fen, corresponding
Length just increases by 0.001 millimeter, uses
The variation that V-type frame V-type face angle to be measured is described in the variation of length is feasible, also is reliable.By the reading on the reading displayed gauge outfit 1, just can determine the V-type face angle difference of V-type frame to be measured and standard V-type frame 7, can determine the V-type face angle of V-type frame to be measured.
