Description
Technical field
The utility model technology is applied to gear measuring center scanning survey field.Be specially a kind of digital quantity scanning feeler accurate mechanical zero resetting device.
Background technology
At present, known scanning feeler machinery zero resetting device, structural instability is more difficult in zero-bit setting.Adopt the gauge head of digital sensors, zero-bit coordinate figure is inaccurate, unstable, and left and right dynamometry is unbalanced, and measurement effect is undesirable.
Summary of the invention
The utility model provides a kind of accurate mechanical zero resetting device of New-type digital quantity scanning feeler, apparatus design is unique, practical reliable, processing, assemble easy, overcome that digital quantity scanning feeler machinery zero resetting device complex structure, coordinate zero-bit are in the past inaccurate, unstable, the unbalanced problem of left and right dynamometry.It is characterized in that: the rotation of lever realizes by connected two sheet springs, and very close to each other, return is accurate.
The utility model solves the technical scheme that its technical matters adopts: connect a lever seat at Pian Huang mechanism stiff end, one end of lever seat fills an adjustable stop screw, measures stroke and protection mechanism for regulating.Lever seat fills two sheet springs, and sheet spring is connected by large stretch of spring pressing plate with lever seat, and sheet spring is connected by two small pieces spring pressing plates with dynamometry lever again, makes to keep between lever and lever seat relatively rotating flexibly.In the moved end of Pian Huang mechanism, connect a Dynamometric support, the pivot screw on Dynamometric support regulates its position, for realizing the adjustment of coordinate zero-bit by rotating.Connect a spring suppport at Pian Huang mechanism stiff end, spring suppport two ends are adjustable apparatus, can the length of regulating spring, realize dynamometry adjustable, and can make the fly back of whole Pian Huang mechanism.Connect a grating frame again at Pian Huang mechanism stiff end, grating frame fills a digital data acquisition grating head.Connect a grating scale frame in Pian Huang mechanism moved end, grating scale frame sticks high-precision grating scale, thus achieve can the digital measurement of the accurate high precision displacement amount of back to zero.
The beneficial effects of the utility model are: have employed simple structure, have been combined into exact figure measurement amount return-to-zero mechanism, handling ease by dynamometry lever, screw fulcrum, adjustable springs, and structure is simple, reliable in function, and cost is suitable for.

Embodiment
Its composition comprises: Pian Huang mechanism stiff end 1, stop screw 2, lever seat 3, sheet spring 4, large stretch of spring pressing plate 5, small pieces spring pressing plate 6, left pivot screw 7, Pian Huang mechanism moved end 8, force-measuring support 9, right pivot screw 10, dynamometer spring 11, spring lock block 12, spring suppport 13, lever 14.In FIG, Pian Huang mechanism stiff end 1 is connected to lever seat 3, be compact siro spinning technology between the two, lever seat 3 installs two sheet springs 4 by large stretch of spring pressing plate 5, and sheet spring 4 is connected with lever 14 by small pieces spring pressing plate 6 again, and wherein sheet spring 4 and lever 14 are compact siro spinning technology, sheet spring 4 and lever seat 3 are compact siro spinning technology, there is stricter requirement for the material of sheet spring and thickness, the elasticity of sheet spring should be ensured, again the elasticity of control strip spring.Lever seat 3 is equipped with stop screw 2, and the movement by stop screw 2 limits measurement stroke, and protects whole gauge head to damage.Pian Huang mechanism moved end 8 connects Dynamometric support 9, Dynamometric support 9 is equipped with left pivot screw 7 and right pivot screw 10.The pivot center of lever 14 is equal to the distance of left pivot screw 7 and right pivot screw 10, object ensures left and right measuring state consistance, position when lever 14 contacts with left pivot screw 7, right pivot screw 10 is simultaneously as reference position, be threaded because pivot screw adopts with lever 14 simultaneously, the reference position of lever 14 can be adjusted by pivot point screw, form zero-bit adjustable structure.Pian Huang mechanism stiff end 1 is connected with spring suppport 13 by elongated hole, spring suppport 13 two ends linking springs briquetting 12, in order to regulate the length of dynamometer spring 11, dynamometer spring 11 has two, wherein one is assisting tension, and mobile spring support 13 can regulate dynamometry size, and requires the gradient simultaneously adjusting two springs, the speed of gauge head back to zero can be adjusted, enable gauge head back to zero quickly and accurately.
In figure 3, when Pian Huang mechanism moved end 8 is subjected to displacement to X+ direction, lever 14 rotates counterclockwise; In the diagram, when Pian Huang mechanism moved end 8 is subjected to displacement to X-direction, lever 14 rotates counterclockwise equally.Because the amount of tension of dynamometer spring 11 is equal, extended state is identical, and lever 14 tends towards stability state all the time.Whole gauge head system, due to the effect of force measuring machine, is tending towards reference position in a free state all the time, thus we using mechanical zero as coordinate zero-bit, the function that the accurate back to zero of digital quantity scanning feeler is consistent with two-way dynamometry can be realized.
