The invention discloses a tool for measuring perpendicularity of a workpiece, comprising a flat base (1), an upright (2) arranged on the flat base (1), a swinging rack (3) hinged with the upright (2) and a lead screw (7), wherein the swinging rack (3) is provided with two measuring heads (6) in a sliding way, the lead screw is respectively in screw-thread fit with the two measuring heads (6) and is axially positioned on the swinging rack (3), the two ends of the lead screw (7) are respectively provided with a first screw thread and a second screw thread which have opposite turning directions, and the two measuring heads (6) are respectively matched with the first screw thread and the second screw thread. In the invention, the lead screw is arranged and axially positioned on the swinging rack, and the two measuring heads are respectively matched with the first screw thread and the second screw thread of the lead screw; since the first screw thread and the second screw thread have opposite turning directions, the two measuring heads can move in the same direction or opposite directions when the lead screw is rotated, and the distance between the two measuring heads is changed so as to be suitable for workpieces to be measured in different sizes.
Description
technical field [0001] The invention relates to the technical field of measuring tools, in particular to a workpiece perpendicularity measuring tool. Background technique [0002] Mechanical parts have positional accuracy requirements, among which verticality accuracy is an important quality index, no matter what quality index needs to pass the test, in order to make a quantitative conclusion. At present, the detection of verticality mostly adopts 90° square and gap method. Measuring verticality with this kind of measuring tool is neither accurate nor efficient, and the final state of some parts cannot be measured. [0003] The Chinese patent application number 02292649.6 discloses a measuring instrument for detecting verticality, which includes a main ruler composed of a base and a scale perpendicular to the base, and also includes a card-type vernier and a rotating shaft, and the card-type vernier is installed through the rotating shaft. On the scale of the main scale an...
