Abstract
The invention discloses a measuring tool for the diameter of an adjustable convergence spout, comprising a positioning support part and an adjustable measuring part, wherein the positioning support part is characterized in that a revolute pair hinge base 2, a central shaft, a strut bar 1, an adjustable bar, a revolute pair hinge base 6 and a support base form a planer four-bar mechanism; the revolute pair hinge base 2 is installed on one end of the central shaft; one end of the adjustable bar is connected to the revolute pair hinge base 2 by a revolute pair, and the other end of the adjustable bar is connected to the strut bar by the revolute pair; and one end of the support base is connected with the strut bar by the revolute pair, and the other end of the support base is supported on the inner wall of a barrel. The adjustable measuring part is characterized in that a support disk is connected to the central shaft by a thread; the strut bar 2 is fixed on the support disk; a slide block base is fixed on the strut bar 2 with scale by bolts; the slide block is connected to the slide block base by a compression spring; and an adjustable disk is installed on the support disk. The measuring tool has the advantages of simple structure and high measurement precision, lowers influence by manual operation factors, is convenient to disassembly and carry, and is suitable for external field maintenance.
Description
technical field [0001] The invention relates to the science in the field of mechanical structures, and in particular provides a measuring tool with adjustable convergent nozzlediameter. Background technique [0002] There are two current ways to measure the diameter of the adjustable convergent spout: one is to use a micrometer rod to measure several points respectively, and then convert the diameter. The other is to measure the circumference of the inner diameter through a complex mechanism through a hydraulic or pneumatic drive. This measuring tool needs to be equipped with a special pneumatic or hydraulic system, and the measuring tool has a complex structure, large volume and weight. , Inconvenient to carry. For this reason, it is necessary to design a measuring tool that can reduce manual repetitive labor, has a simple structure, and is easy to disassemble and carry. Contents of the invention [0003] The object of the present invention is to provide a measuring to...
