Tool and method for detecting concentricity of vacuum tubes of inner and outer foaming barrels of solar water tank

Abstract

The invention discloses a tool for detecting the concentricity of vacuum tubes of inner and outer foaming barrels of a solar water tank. The tool comprises a main tool body, wherein the main tool body takes the shape of a stepped cylinder; the shape and the size of the head of the main tool body are matched with those of the vacuum tubes of the inner and outer foaming barrels of the solar water tank; a spirit bubble is mounted at the tail part of the main tool body; the plane of the tail part is superposed with the center axis of the plane of a contact part between the spirit bubble and the main tool body; the spirit bubble has deflection degree scales. The invention further discloses a detection method utilizing the tool. The method comprises the following steps of horizontally placing the water tank, positioning a vacuum tube hole in the top end of the water tank, and inserting the detection tool into the vacuum tube hole; providing guidance for the main tool body by the vacuum tube hole which is formed by foaming, and visually reading the degree of an eccentric angle of a liner of the water tank and the outer barrel of the water tank in the spirit bubble. The detection tool has the advantages of simple structure, convenience in production and low cost, the detection method is simple and convenient, the foaming quality of the water tank can be visually detected, and defective products are eliminated, so the overall quality of products is improved.

Description

technical field [0001] The invention relates to a concentricity detection tool and method, in particular to a concentricity detection of vacuum tubes inside and outside a solar water tank, and belongs to the technical field of solar water heater detection. Background technique [0002] At present, there is no effective means to detect whether the vacuum tubes of the inner tank and the outer barrel are concentric after the solar water tank is foamed, resulting in water leakage from the vacuum tube holes in some non-concentric water tanks when they are factory installed, which greatly causes waste of cost and personnel, and also causes consumption. The group has less trust in solar products. There is an urgent need in the solar industry for a detection method that can visually detect the concentricity of the vacuum tubes inside and outside the solar water tank. Under this background, this detection method was designed and developed. Contents of the invention [0003] The te...
