Abstract
The utility model relates to a rotation angle measuring appliance. When a rotating shaft of a face to be measured is difficult to approach or has no regular plane used as a measuring reference plane, a support seat flexibly installed can be used for optionally selecting position directions so that the utility model carries out rotation angle measurement to the face to be measured on any tangent plane. The rotation angle measuring appliance is composed of a fixed support seat (1), a connecting rod (2) and a measuring rod (3), wherein both ends of the connecting rod (2) are respectively provided with shaft pins (4) (5); the fixed support seat (1) is connected with the connecting rod (2) through the shaft pin (4); the measuring rod (3) is connected with the connecting rod (2) through the shaft pin (5). As long as the shaft pins (4) and (5) are respectively provided with an angle measuring sensor or lines are engraved besides the shaft pins (4) and (5), the values of angles a, a' and b can be measured, and furthermore, the rotation angle x of a body to be measured is calculated according to the formula: angle x=(angle a-angle a') +angle b.
Description
Technical field
The utility model relates to a kind of angle detecting device, and this is a kind of mechanical type outer corner measurement instrument of being made up of linkage assembly.
Background technology
The tested surface rotating shaft can't near or when not having regular planar as the measuring basis plane; Machinery angle measurement measurer is difficult to measure the tested surface corner.Therefore, when for example accurately measuring with the corner of the similar tested surface of rudder face, industrial general just pretty troublesome as the mechanical measurer of measuring corner, the purpose of this utility model provides a kind of for solving the angle detecting device of outer corner measurement under this difficult circumstances.
Summary of the invention
The related angle detecting device of the utility model is by fixed pedestal, connecting rod, and sounding rod, parts such as pivot pin are formed.Pedestal can be a magnet base, vacuum adsorption base or cramp frame, and measuring appliance can be installed near the fixed object of tested surface apace.Sounding rod abuts against on the tested surface, and connecting rod is that pivot pin is connected with sounding rod, and connecting rod also is that pivot pin is connected with hold-down support; When tested surface rotated, also thereupon changeing with respect to connecting rod, connecting rod also rotated with respect to hold-down support sounding rod simultaneously; Arbitrary position of plane of rotation can be decided to be the rotation benchmark, after plane of rotation rotates a certain angle, the sounding rod of Zhuan Donging all is easy to predict with any conventional method with respect to the corner of connecting rod and the connecting rod corner with respect to bearing thereupon, just can obtain the tested surface corner through the simple geometry computing again.
Because this clinometer rule is simple in structure, easy to use, by erection support flexibly, the optional position direction also can be measured the corner in different tangent planes orientation.
Appended drawings is the structural drawing of the utility model embodiment.
Clinometer rule is by pedestal (1) in the accompanying drawing, connecting rod (2), and sounding rod (3) and pivot pin (4), (5) five parts are formed.
Tested surface is AX, and X is its center of rotation, and the sounding rod of clinometer rule (3) abuts against on the AX, and at this moment sounding rod (3) and connecting rod (2) are shown in the dotted line in the accompanying drawing.After tested surface turned to A ' X, sounding rod of measuring appliance (3) and connecting rod (2) were shown in the solid line in the accompanying drawing, and ∠ x is the corner of tested surface among the figure.As long as by scale method or other any angular displacement sensors, measure sounding rod before with respect to the rotation of connecting rod angle (a) and rotate after angle (a ') when measuring simultaneously connecting rod again with respect to the corner (b) of bearing, just can count grate and go out tested surface corner ∠ x.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified embodiment.
Tested surface is AX, and X is its center of rotation, and above the sounding rod of clinometer rule (3) abutted against, at this moment sounding rod (3) and connecting rod (2) were all shown in the dotted line in the accompanying drawing.After tested surface turned to A ' X, sounding rod of measuring appliance (3) and connecting rod (2) were shown in the solid line in the accompanying drawing.∠ x is the corner of tested surface on the figure, measuring object just, and ∠ a is the original angle of sounding rod (3) and connecting rod (2); ∠ a ' rotates the angle of back sounding rod (3) and connecting rod (2) for measured body AX; ∠ b is the angle that connecting rod (2) rotates.By two triangles at this place, four angles as can be known:
∠x+∠a＝∠a’+∠b
Or ∠ x=(∠ a '-∠ a)+∠ b
As long as in (4), (5) diaxon pin assembly angular measurement sensor or in (4), (5) two pivot pins are close to groove or adorn other any angular displacement sensors, just can measure ∠ a, ∠ a ', ∠ b three is worth, and then calculates the corner ∠ x of tested surface.More precisely, ∠ x is the corner in clinometer rule connecting rod (2) rotational plane, if this plane is the tested surface corner perpendicular to measured body rotating shaft X.
Claims (2)
1, the utility model relates to a kind of angle detecting device, it is by hold-down support (1), connecting rod (2), sounding rod (3) three parts are formed, it is characterized in that: the two ends of connecting rod (2) have a pivot pin (4) and (5) respectively, hold-down support (1) links to each other with connecting rod (2) by pivot pin (4), and sounding rod (3) links to each other with connecting rod (2) by pivot pin (5).
2, angle detecting device as claimed in claim 1 is characterized in that described bearing can be a magnet base, vacuum adsorption base or cramp frame.
