Checking tool and testing method for matching size of open end of cup-shaped rotary body parts

Abstract

The invention relates to a cup-shaped revolution body part opening end cooperative size detection tool and detection method. The detection tool and the detection method are used for measuring the distance from a virtual intersection line or intersection point (32) of two faces or multiple faces with transitions arranged on an inner cylinder and an outer cylinder of a cup-shaped revolution body part. An external height detection tool module (1) and an inner depth detection tool module are adopted and a height gauge is used for measuring the distance from the virtual intersection line or the intersection point (32) to an opening end face (31) of the two faces or multiple faces with transitions arranged on the inner cylinder and the outer cylinder of the cup-shaped revolution body part. Compared with the prior art, the provided detection tool is capable of measuring the size that a current measuring tool fails to directly measure, and is high in measurement accuracy and precision, low incost and convenient to use.

Description

Technical field [0001] The invention relates to the detection field of cup-shaped revolving body parts, in particular to a checking tool and a detection method for the matching size of the opening ends of the cup-shaped revolving body parts. Background technique [0002] Nowadays, people have paid great attention to health preservation and are more and more concerned about drinking water demand. As a healthy, environmentally friendly, convenient and durable portable water cup, the stainless steel vacuum flask is of course exquisite workmanship. The thermos cup must not only have good heat preservation performance, but also have reliable sealing performance. After tightening the upper cover, ensure that it does not leak water or wet the clothes. The stainless steel vacuum insulation cup body (cup body) is mainly composed of an inner layer and an outer layer, and the gap between the inner layer and the outer layer is called the vacuum layer. The inner layer is also called the inn...

Problems solved by technology

[0003] Since the mouth shape of the inner cylinder and the outer cylinder of the stainless steel thermos cup is mostly arc surface, inclined surface, and short plane, the longitudinal height dimension from the shoulder and water-stop rib to the end face of the drinking water outlet cannot be directly measured accurately.

If a three-coordinate measuring instrument is used for detection, on the one hand, the cost of the instrument is high, on the other hand, the measurement environment and maintenance requirements are high, and it is overkill to measure common daily necessities for thermos cups

In the current mass production of enterprises, it is useful to visually mark and measure height gauges, to compare non-standard calipers marked with engraved lines, and to confirm the fitting of upper covers one by one. These methods are not only from the error of size measurement, but also the feasibility of assembly line operation and The online quality inspection of the quality control department fails to meet the normative standards and quality efficiency of production operations
