Abstract
The invention relates to an angle measuring device. A clamping pin is movably connected on a fan-shaped dial plate, and is of a T-shaped structure. An intersection point of three sides of the T-shaped structure is overlapped with a fan-shaped circle center of the dial plate. Two ends of clamping pin of the T-shaped structure are pointer-shaped, and are located in a degree region of the dial plate, and the other extending end is a positioning end; and a positioning block is connected outside the dial plate. A measuring end surface of the positioning block and a start mark of the dial plate are in the same horizontal plane. The angle measuring device improves measuring accuracy of an angle between a sheet metal part web plate and a tangent plane of a bent side, simplifies operation steps, improves measuring efficiency and intuitively reflects change conditions of angles of a part.
Description
Technical field
The present invention relates to a kind of angle measurement unit, belong to the mechanical measurement technique field.
Background technology
Some metal plate parts on the aircraft are when testing, need to measure part web face and crimp in the angle at certain tangent plane place, when measuring, normally tighten at part tangent plane place with the V-arrangement slide calliper rule, take off the V-type slide calliper rule then, measure V-arrangement slide calliper rule both sides angulation with protractor.Because when getting the angle, can not fit fully with part in V-arrangement slide calliper rule both sides, just cause and occur error when getting the angle, and then influence measuring accuracy, simultaneously, measuring process is comparatively complicated, when measuring varied angle, need measure at a plurality of tangent planes place, it is lower not only to measure efficient, and can not reflect the situation of change of angle intuitively.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of angle measurement unit, and this angle measurement unit improves the measuring accuracy of sheet metal part web and crimp shear-face angle, and the step that simplifies the operation improves and measures efficient, reflects the situation of change of part angle intuitively.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of angle measurement unit, flexibly connect the card pin at fan-shaped dial plate, the card pin is T type structure, three limit intersection points of T type structure overlap with the fan-shaped center of circle of dial plate, wherein two ends are arranged is the pointer shape to T type structure card pin, is positioned at the number of degrees district of dial plate, and another external part is positioning end; At the locating piece that is externally connected to of dial plate, the measurement end face of locating piece and the start index of dial plate are on same surface level.
Described dial plate is the covering of the fan structures of 90 degree, is provided with the number of degrees of 90 degree scopes at the excircle of fan-shaped dial plate, and each number of degrees point is made as through hole.
This angle measurement unit adopts covering of the fan and T type card needle construction, and the locating piece that connects by the outside and the positioning end of card pin can measure the angle of panel beating bent angle, uses fast, and reading is accurate.

Embodiment
As shown in Figure 1 to Figure 3, a kind of angle measurement unit, flexibly connect card pin 2 at fan-shaped dial plate 1, card pin 2 is T type structure, three limit intersection points of T type structure overlap with the fan-shaped center of circle of dial plate 1, wherein two ends are arranged is the pointer shape to T type structure card pin 2, is positioned at the number of degrees district of dial plate 1, and another external part is positioning end 5; Dial plate 1 be externally connected to locating piece 3, the measurement end face 4 of locating piece 3 and the start index of dial plate 1 are on same surface level.
Described dial plate 1 is the covering of the fan structures of 90 degree, is provided with the number of degrees of 90 degree scopes at the excircle of fan-shaped dial plate, and each number of degrees point is made as through hole.
As shown in Figure 4, when carrying out measurement of angle, the measurement end face 4 of locating piece 3 is fitted with the web face of sheet metal part, and the tangent plane that dial plate 1 and institute location are put overlaps, revotating card pin 2 is stuck on the crimp of sheet metal part the positioning end of card pin 2, blocks the other both sides of pin then, which limit is in dial plate, and the number of degrees of indication are the crimp angle numerical value of panel beating.
