Description
Technical field
The present invention relates to a kind of survey instrument, relate in particular to a kind of front inclination angle measurement mechanism for motorcycle.
Background technology
The motorcycle top rake is an important technical parameter of motorcycle, is directly connected to the stress of motorcycle in motion process and rides comfortableness.The size of motorcycle top rake is the angle of front damper and vertical guide, and according to the difference of vehicle, the size of top rake is also variant.The measuring method of the motorcycle top rake that present motorcycle manufacturer is adopted, be that motorcycle is placed on the flat board, carry out by angle square and by corresponding auxiliary member, the size of top rake must be calculated according to measurement result, so not only loaded down with trivial details, not directly perceived, and measuring speed is slow, for measure batch, the labour intensity of survey crew is bigger; Simultaneously, it is also inaccurate to measure the numerical value that is obtained, and makes motorcycle production be difficult to reach conforming requirement.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of front inclination angle measurement mechanism for motorcycle, with the accuracy of effective raising measuring speed and measurement result.
Technical scheme of the present invention is as follows: a kind of front inclination angle measurement mechanism for motorcycle, on the substrate that an end face is the plane, offer a semicircular groove, this groove is sealed by the transparent panel that covers substrate surface, and the straight flange of groove is parallel and adjacent with the end face of substrate; In described groove pointer is set, the top of this pointer is hinged on the middle part of substrate upper end, is fixed with weight on the needle point of pointer bottom; Be provided with scale mark and be furnished with scale value on described transparent panel, described scale mark evenly distributes by circular arc, and the center of circle of this circular arc is positioned on the center extended line of described pointer hinge, and the two-end-point of the center of circle of circular arc and circular arc is on same straight line.
Adopt above technical scheme, because the top and the substrate of pointer are hinged, pointer can rotate flexibly around hinge; Be fixed with weight on the needle point of pointer bottom, when substrate rotated, under the effect of weight gravity, pointer can remain state straight down.The end face of substrate is a measurement face among the present invention, and the end face of substrate is parallel with surface level when initial, and perpendicular with pointer.When carrying out the measurement of motorcycle top rake, earlier motorcycle is placed on the measuring table of level, then motorcycle direction handle is just pulled, hand-held again the present invention, the measurement face of substrate is abutted against on the trailing flank of front damper of motorcycle, because the end face of substrate has with respect to the horizontal plane rotated certain angle, and pointer keeps straight down, can draw the size of motorcycle top rake according to pointer scale mark pointed and by scale value this moment.
Adopting the present invention to carry out the motorcycle top rake measures, not only simple, convenient, and accuracy is good, if be used for measure batch, can effectively reduce staff's labour intensity, guaranteeing that measurement structure accurately, simultaneously reliably, has improved measuring speed greatly, make motorcycle production can satisfy conforming requirement.
Be provided with an arc-shaped rail groove that communicates with it in the outside on above-mentioned groove circular arc limit, both centers of circle coincide, and described weight is arranged in this guide-track groove.When pointer rotated, guide-track groove play the guiding role to weight; Guide-track groove communicates with groove, so that pointer can freely rotate.
Bottom land in above-mentioned groove upper center offers deep gouge, in this deep gouge damper is installed, and the top of described pointer and this damper are hinged.Damper plays buffering, and speed slowed down when pointer was rotated, and can prevent that pointer is damaged because of sharply rotating, and can avoid pointer to swing because of inertia when measuring again.
Above-mentioned scale value is positioned at the inboard of scale mark, and to be positioned at the scale value that scale mark forms circular arc arc top place be 90, reduces successively to the deflection scale value of circular arc end points from the arc top, and the scale value at circular arc end points place is 0.Scale value is according to the upper type setting, and pointer scale mark pointed is the size of motorcycle top rake during measurement, can directly read with reference to scale value, and is very directly perceived.
Beneficial effect: the present invention can be simply, apace the top rake of motorcycle is measured, and can obtain measurement result intuitively, exactly, for measure batch, can effectively reduce staff's labour intensity, ensure that motorcycle production satisfies conforming requirement, have be skillfully constructed, simple in structure, implement characteristics such as easy.
