Description
Technical field
The present invention relates to a kind of machining accuracy and measure, specifically is a kind of shaft key groove symmetry measurement mechanism.
Background technology
The measurement of shaft key groove symmetry is widely used in motor, lathe, automobile making and all axial workpieces with the keyway connection.At present, shaft key groove symmetry measuring method is mainly measured with V shape iron, flat board, dial gauge and gauge stand common name signing method.This method operation is not convenient, and measurement means is loaded down with trivial details, and precision reliability is poor.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of shaft key groove symmetry measurement mechanism.
The present invention adopts following technical scheme to realize: a kind of shaft key groove symmetry measurement mechanism, it comprises by main scale, is fixed on the stiff end of main scale one end and is installed in the V-arrangement vernier caliper that mobile terminal that main scale one end can horizontal direction moves on main scale is formed, the right measuring claw of keyway left side measuring claw and keyway is installed on the main scale of V-arrangement vernier caliper, upper end at keyway left side measuring claw is equipped with dial gauge, by lever shaft the movable levers part is installed in the lower end of keyway left side measuring claw; On the measuring point of movable levers part and the right measuring claw of keyway measuring point, respectively be drilled with a through hole, be pressed into steel ball in the through hole.
The invention has the beneficial effects as follows: simple in structure, easy to operate, the precision height, in light weight, be easy to carry, be the desirable survey instrument of implementing form and position tolerance and measurement axis keyway symmetry.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, V-arrangement vernier caliper, 1.1, main scale, 1.2, V-arrangement main scale stiff end, 1.3, V-arrangement main scale mobile terminal, 2. keyway left side measuring claw, 3, dial gauge, 4, trip bolt, 5, movable levers, 6, lever shaft, 7, the right measuring claw of keyway, 8, steel ball, 9, the right measuring claw fine setting of keyway, 10, the fine setting of V-arrangement main scale mobile terminal.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in drawings, shaft key groove symmetry measurement mechanism comprises by main scale 1.1, is fixed on the stiff end 1.2 of main scale 1.1 1 ends and is installed in the V-arrangement vernier caliper 1 that mobile terminal 1.3 that main scale 1.1 1 ends can horizontal direction moves on main scale 1.1 is formed, the right measuring claw 7 of keyway left side measuring claw 2 and keyway is installed on the main scale 1.1 of V-arrangement vernier caliper 1, upper end at keyway left side measuring claw 2 is equipped with dial gauge 3, and dial gauge 3 usefulness bolts and fixed support 4 are installed on the measuring claw 2 of a keyway left side.Lower end at keyway left side measuring claw 2 is equipped with movable levers part 5 by lever shaft 6; On the measuring point of movable levers part 5 and the right measuring claw of keyway 7 measuring points, respectively bore a through hole, be pressed into steel ball 8 in the through hole.Right measuring claw 7 opposite sides of keyway are equipped with the right measuring claw fine setting 9 of keyway on main scale.V-arrangement main scale mobile terminal fine setting 10 is equipped with in the outside of mobile terminal 1.3 on main scale.Movable levers part 5 produces by 10: 1 lever ratio sizes, is pressed into steel ball 8 in the through hole of a pair of keyway measuring point, gets two spheric probe holes (two axially bored lines should perpendicular to the lever shaft axially bored line).
Using method is for example: dial gauge 3 gauge heads to movable levers axis hole is of a size of 70 ± 0.005 position punching, at the movable levers axis hole to keyway gauge head size 7 ± 0.005 places.To guarantee that at last dial gauge 3 gauge heads to movable levers 5 axis hole sizes are 10: 1 with movable levers axis hole to keyway gauge head size ratio.The dial gauge anchor clamps are installed in measuring claw 2 upper ends, a keyway left side and fix; Load onto dial gauge 5, movable levers 5 with etalon (outside micrometer, ring gauge, slip gauge assembly etc.), is pressed the size check and correction of measured piece, and at this moment the scale theoretical value of dial gauge is 1 micron.When the shaft key groove symmetry is measured, suitably adjust V-arrangement main scale stiff end 1 among the figure, V-arrangement main scale mobile terminal 1.3, the fine setting 10 of V-arrangement main scale mobile terminal to correct position according to the measured axis size, suitably adjust among the figure keyway left side measuring claw 2, movable levers 5, the right measuring claw 7 of keyway, the right measuring claw fine setting 9 of keyway to 8 liang of gauge head engagement shafts of steel ball keyway, two measurement faces according to the size of shaft key groove again, and read the dial gauge minimum value and be set to zero-bit.Use same quadrat method, select the different measuring face again on shaft key groove, dial gauge obtains maximum deflection difference value, carries out suitable conversion and just obtains the symmetry error value, so just can judge shaft key groove symmetry qualification.
