Abstract

The invention relates to the technical field of machine tool fixtures, particularly to a novel angle ruler. The novel angle ruler comprises a ruler; ruler scale lines are located at the bottom edge of the ruler; scales are located above the scale lines; the front end of the ruler is fixedly connected with a fan-shaped main ruler; the fan-shaped main ruler is connected with an arc-shaped auxiliary ruler with scales; the arc-shaped auxiliary ruler is provided with an arc-shaped guide rail; the fan-shaped main ruler is provided with a guide column which is matched with the arc-shaped guide rail. According to the novel angle ruler, the length of a workpiece with one angle which is a circular arc can be rapidly measured.

Description

Novel angle square
Technical field
The present invention relates to jig technical field, particularly relate to Novel angle square.
Background technology
One jiao is the workpiece of circular arc, and the intersection point on two limits tangent with circular arc has dropped on outside the entity of part, now directly cannot be measured the length of part by vernier caliper, and when measuring this length, need the auxiliary of other survey instruments a large amount of, measuring process is comparatively loaded down with trivial details.
Summary of the invention
The object of this invention is to provide a kind of can Quick Measurement one jiao be the Novel angle square of circular arc works length.Technical scheme of the present invention is as follows:
Novel angle square, comprises ruler; Described ruler scale mark is positioned at edge at the bottom of ruler, and described scale is positioned at above scale mark; Described ruler front end is fixedly connected with fan-shaped main scale, this fan-shaped main scale is connected with the secondary chi of arc with a scale; The secondary chi of described arc is provided with arc-shaped guide rail; Described fan-shaped main scale be provided with arc-shaped guide rail with the use of guidepost.
Described guidepost and arc-shaped guide rail contact jaw are provided with rotating pulley.Reduce friction force when guidepost and guide rail contact.
The invention has the beneficial effects as follows: by ruler with a scale, and around the secondary chi of the arc with a scale of fan-shaped main rotation, angle and the length of the part of measuring tape fillet simultaneously can be realized; The operating process of not only measuring is simple, and Novel angle square structure is simple, and cost of manufacture is low.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is the first embodiment structural representation of the present invention;
Fig. 2 is the second embodiment partial sectional view of the present invention;
In accompanying drawing, 1 is ruler, and 2 is fan-shaped main scale, and 3 is the secondary chi of arc, and 4 is arc-shaped guide rail, and 5 is guidepost, and 6 is pulley, and 7 is workpiece.
Embodiment
The first embodiment of the present invention, as shown in Figure 1, Novel angle square, comprises ruler 1; Described ruler 1 scale mark is positioned at edge at the bottom of ruler, and described scale is positioned at above scale mark; Described ruler front end is fixedly connected with fan-shaped main scale 2, this fan-shaped main scale 2 is connected with the secondary chi 3 of arc with a scale; The secondary chi 3 of described arc is provided with arc-shaped guide rail 4; Described fan-shaped main scale be provided with arc-shaped guide rail 4 with the use of guidepost 5.
During measurement, first fan-shaped main scale 2 aimed at ruler 0 ° of position and make two measurement limits in 90 °, the both sides that two measure limits alignment pieces 7 respectively, by the zero position of ruler, then can be read angle and the length dimension of part by recycling square chi simultaneously.
Because the secondary chi 3 of arc can rotate around guidepost 5, due to guidepost 5 contact with guide rail 4 time, friction force comparatively greatly, easily makes guidepost and way rub; For the problems referred to above, the second embodiment of the present invention, shown in Figure 2, described guidepost 5 is provided with rotating pulley 6 with arc-shaped guide rail 4 contact jaw.Reduce friction force when guidepost and guide rail contact.
