Combined coil inspection tool

Abstract

The invention provides a combined coil inspection tool and belongs to the field of coil inspection tools. The inspection tool solves the problem in the prior art that the existing detection manner is low in measurement accuracy, long in measurement time and low in measurement efficiency. According to the technical scheme of the invention, the combined coil inspection tool comprises a positioning shaft, an upper block and a base. The maximum outer diameter of the positioning shaft is just the standard size of the inner diameter of a coil. The base is composed of a base substrate. The center of the base substrate is provided with a base sliding hole matched with the positioning shaft. The upper surface of the base substrate is provided with a lower center positioning piece. On one side of the base sliding hole, the base substrate is provided with a base reference dimension hole. At the middle-lower part of the base reference dimension hole, the base substrate is pre-provided with a lower center height measurement groove. The upper block is composed of an upper block substrate. The center of the upper block substrate is provided with an upper block sliding hole matched with the positioning shaft. The lower surface of the upper block substrate is provided with an upper center positioning piece. On one side of the upper block sliding hole, the upper block substrate is provided with an upper block center dimension hole. At the middle-upper part of the upper block center dimension hole, the upper block substrate is pre-provided with an upper center height measurement groove.

Description

Technical field: [0001] The invention belongs to the field of coil inspection tools, in particular to a combined coil inspection tool. Background technique: [0002] Coils are usually made of metal wire. In the control of its production process, the coil size needs to be strictly controlled, such as the inner diameter of the coil, the center size of the coil, the size from the center of the coil to both ends, and the length of both ends. , will have a crucial impact on the coil performance of the final product. [0003] At present, when inspecting the coil size in the prior art, the inspection is usually carried out manually using ordinary measuring tools, and two sets of inspection tools and a height gauge are required to measure the length from the center to both ends and the lengths at both ends respectively. The center size and inner diameter need to be measured with a special inspection tool using a two-dimensional projection. The measurement time is long and it is di...
