Embodiment
[0020] A three-dimensional arc rod inspection tool, such as figure 1 , figure 2 As shown, the inspection tool includes a base 1, a fixed beam 2 and a curved surface template 3, the curved surface template 3 is connected to the base 1 through the fixed beam 2, and two three-dimensional curved surface projection positioning curves 4 are arranged on the upper surface of the curved surface template 3. A number of fixed blocks 5 are arranged between the two three-dimensional curved projection positioning curves 4 . Wherein, the base 1 is an L-shaped plate. The fixed beam 2 is a short bar perpendicular to the base 1 . The fixed block 5 locates the curvature of the three-dimensional curved surface projection and locates the curve 4 . Generally, there are 10 to 100 fixing blocks 5 , and in this embodiment, there are 20 fixing blocks 5 .

Description
technical field [0001] The invention relates to a checking tool, in particular to a three-dimensional arc rod checking tool. Background technique [0002] In the production of the bus frame, the radian inspection tool for the entire body surface is generally made, and then the arc rods used for the frame are made according to the model, and finally assembled together to complete the production of the entire frame. At present, most of the templates used in the production of arc rods are single-sided projection templates, which have large errors and are difficult to effectively and quickly complete large-scale work. Contents of the invention [0003] The object of the present invention is to provide a three-dimensional arc rod inspection tool with simple structure, convenient use and greatly improved production efficiency in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through the following tec...
