Verticality testing tool

Abstract

The invention discloses a quick verticality testing tool for testing verticality of a metal insert in a product. Electric testing is utilized. The upper end surface of an equipment base is downwards provided with a vertical slot. The verticality between the vertical slot and the upper end surface of the base are same with the verticality requirement of a qualified product metal insert. The shape of the vertical slot is same with that of the metal insert. The depth of the vertical slot is larger than the length of the metal insert. After the metal insert is inserted into the vertical slot, themetal insert is same with the side clearance of the vertical slot and the verticality tolerance of the metal insert. The sidewall of the vertical slot is made of a conductive material and is connectedwith a testing circuit through a conductive cable. If verticality of a metal insert pin is qualified, the metal insert pin does not contact with the sidewall of the vertical slot on the base, and a relay control signal lamp is lightened normally; and otherwise, the flexibility of the metal insert pin is overhigh, the metal insert pin contacts with the sidewall of the vertical slot and shortcirucit is caused, and the realy control signal lamp is extinguished. A verticality condition of the metal insert pin can be visually reflected. The quick verticality testing tool has advantages of simple equipment, reliable testing result, time saving in operation and high testing efficiency.

Description

technical field [0001] The invention relates to a detection device, in particular to a verticality inspection tool. Background technique [0002] In the field of machinery manufacturing, the shape, size and structure are important indicators of whether the product is qualified or not. It is necessary to use various testing tools to test the above parameters. The tools that can be used for parameter testing are collectively called inspection tools. For important The product parameters often need to be measured by more complex detection methods or special inspection tools. [0003] For example, perpendicularity is a relatively complex geometric tolerance, and its detection generally requires professional measuring instruments, such as three-coordinate measuring instruments. If three-coordinate measurement is used, professional surveyors are required. When measuring, it is necessary to use the three-coordinate points to construct the datum first, and then use the three-coordi...

Problems solved by technology

This detection method is simple and convenient to operate, but the detection result is inaccurate, and it is not suitable for the verticality detection of products that require high verticality; at the same time, it is necessary to hit the correction block with a hammer to correct the verticality, and this mechanical impact lasts for a long time It will greatly reduce the test accuracy, and the test results will be inaccurate
