Abstract
Groove profile knife edge angle square provided by the utility model, including Rectangular knife edge chi main scale, Rectangular knife edge chi main scale is fixedly connected with straight edge ruler secondary ruler, the notch of side composition " V " font structure in straight edge ruler secondary ruler and Rectangular knife edge chi main scale, wherein, notch is in contact with the outer surface of curved surface part.The utility model can carry out the measurement and line, the measurement at right angle, the measurement line of curved surface axial straightness and the measurement of the transversal perpendicularity of curved surface of plane and straight line degree, simultaneously practical and various section bars and parts, such as plane, column type, square, cast etc., it is easy to use, measurement accuracy is also improved simultaneously, good generalization has been widely used to later measurer.
Description
Technical field
It the utility model is related to straightness measuring tool field, more particularly to groove profile knife edge angle square.
Background technology
Common straight edge ruler and knife edge angle square measurement or line can only be confined on plane geometry workpiece, three-square rule and four
Although rib chi can be measured or be rule with that on curved surface, can not do curved section vertical survey work.
The content of the invention
The purpose of this utility model is to provide groove profile knife edge angle square solve existing chi tool and be unable to direct measurement curved surface
The problem of perpendicularity in section and axially line.
In order to achieve the above object, the technical solution adopted in the utility model is as follows：
Groove profile knife edge angle square provided by the utility model, including Rectangular knife edge chi main scale, Rectangular knife edge chi main scale, which is fixed, to be connected
It is connected to straight edge ruler secondary ruler, the notch of side composition " V " font structure in straight edge ruler secondary ruler and Rectangular knife edge chi main scale,
Wherein, notch is in contact with the outer surface of curved surface part.
Preferably, the angle of notch is 120 °.
Preferably, Rectangular knife edge chi main scale is fixedly connected with straight edge ruler secondary ruler.
Preferably, Rectangular knife edge chi main scale and straight edge ruler secondary ruler are welded to connect.
Preferably, Rectangular knife edge chi main scale includes the first right-angle side and the second right-angle side, wherein, the first right-angle side and second
Right-angle side is of an L-shaped structure arrangement, and the length of the first right-angle side is more than the length of the second right-angle side.
Preferably, the inner edge of straight edge ruler secondary ruler is welded to connect with the first right-angle side.
Compared with prior art, the beneficial effects of the utility model are：
Groove profile knife edge angle square provided by the utility model, notch is buckled on curved surface, passes through the outside of straight edge ruler secondary ruler 2
Observe the linearity of curved surface；Then it is its perpendicularity of observable and section linearity to be placed with main scale most short right-angle side on section.
The utility model can carry out the measurement and line, the measurement at right angle, the measurement of curved surface axial straightness line of plane and straight line degree
With the measurement of the transversal perpendicularity of curved surface, while practical with various section bars and parts, such as plane, cylindrical type, square, cast etc.,
It is easy to use, while measurement accuracy is also improved, good generalization has been widely used to later measurer.
Further, 120 ° of angles of notch so that notch coordinates closer with curved surface.
Brief description of the drawings
Fig. 1 is the front view of notch knife edge angle square；
Fig. 2 is the side view of notch knife edge angle square；
Fig. 3 is the use state figure of notch knife edge angle square；
Wherein, 1, Rectangular knife edge angle square main scale 2, straight edge ruler secondary ruler.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is further described.
As shown in Figure 1 and Figure 2, groove profile knife edge angle square provided by the utility model, including Rectangular knife edge chi main scale 1 and the edge of a knife
Ruler secondary ruler 2, wherein, Rectangular knife edge chi main scale 1 includes the first right-angle side and the second right-angle side, wherein, the first right-angle side and
Two right-angle sides are of an L-shaped structure arrangement, and the length of the first right-angle side is more than the length of the second right-angle side.
The inner edge of straight edge ruler secondary ruler 2 is welded to connect with the first right-angle side, forms the groove of " V " font structure between the two
Mouthful, and the angle of notch is 120 °.
As shown in figure 3, when in use, such as notch is buckled on curved surface, curved surface is observed by the outside of straight edge ruler secondary ruler 2
Linearity；As measure its curved cross section whether with curved vertical, as long as first notch button on curved surface, then with main scale
It is its perpendicularity of observable and section linearity that most short right-angle side, which is placed on section,.It is entirely comparatively simple using process, gather around simultaneously
There is functional, the hoisting tool use quality of common edge of a knife type chi.
