Embodiment Construction

[0016] As shown in the figure, a curved ruler is composed of a curved box beam 2, and several small curved bodies 1 are attached to the inner and outer curved surfaces of the curved box beam 2. The upper surfaces of all the small arc-shaped bodies 1 on the inner arc surface of the box beam 2 are on the same arc surface, and the lower surfaces of all the small arc-surface bodies 1 attached to the outer arc surface of the curved box beam 2 are on the same arc surface. The distribution of the small arcuate bodies 1 on the inner arcuate surface and outer arcuate surface of the arc-shaped box beam 2 is mosaic-like. The length and width of the small arcuate body 1 are 30-60 mm×30-60 mm, and the thickness of the small arc-shaped body 1 is 3-10 mm. The material of the small arc-shaped body 1 is glass, ceramics, hard plastic, hard rubber or metal.

[0017] The process steps of its production are: the process steps are: First make the inner arc mold tire and the outer arc mold tire w...

Abstract

The invention discloses an arc surface ruler, which consists of an arc box beam. A plurality of small arc surface bodies are adhered to the inner arc surface and the outer arc surface of the arc box beam; the upper surfaces of all the small arc surface bodies adhered to the inner arc surface of the arc box beam are positioned on the same arc surface; and the lower surfaces of all the small arc surface bodies adhered to the outer arc surface of the arc box beam are positioned on the same arc surface. The arc surface ruler has high rigidity, light weight and low price.

Description

technical field [0001] The invention relates to an arc-shaped ruler, in particular to a flat ruler for detecting flatness. Background technique [0002] The curved ruler is a measuring tool commonly used in foundry, metallurgy, machinery manufacturing and other industries. The arc-shaped ruler of the prior art is formed by precision machining of a casting in the shape of an I-beam through a numerically controlled milling machine. Its disadvantage is that the quality is relatively large, and it is cumbersome and laborious to use. In addition, its production efficiency is low, and its manufacturing cost is also high. Therefore, it is a technical problem to be solved at present to design a novel arcuate ruler with light weight and low price with the same rigidity as the cast arcuate ruler. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light-weight and low-cost arcuate ruler with the same rigidity as the cast...
