Problems solved by technology
[0003] Usually, in the process of using a three-coordinate measuring instrument, we often encounter some troublesome problems: that is, using three-coordinate and other methods to measure the same size, but the results obtained are inconsistent
The reason is that the existing three-coordinate equipment does not have an accessory to check the accuracy, and the metrology institute only audits and checks the accuracy once a year, so it is difficult to find out whether the accuracy of the equipment is correct during use, and therefore there are certain potential errors in the detection of parts. Produce substandard products

Embodiment Construction
[0024] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment. It should be understood that the "upper", "lower", "left", "right", "front" and "reverse" mentioned in the following embodiments of the present invention are all based on the directions shown in the figures, These words used to limit the direction are only for the convenience of description, and do not represent limitations on the specific technical solutions of the present invention.
[0025] The principle of three-coordinate detection: The three-coordinate measuring machine is a rectangular coordinate system established by three mutually perpendicular motion axes X, Y, Z. All movements of the probe are carried out in this coordinate system, and the movement track of the probe Represented by the center of the ball. When meas...

The invention discloses a tool for calibrating the precision of three coordinates. The tool for calibrating the precision of the three coordinates comprises a base plate, a hinge assembly and a measuring tool holder assembly. The hinge assembly comprises a hinge seat, a hinge head and a hinge pin. The hinge seat comprises an inserting head and clamping plates, the inserting head is inserted in the base plate in an interference fit mode, the hinge head is inserted between the clamping plates and is hinged to the hinge seat through the hinge pin, and the top end of the hinge head is fixed to the measuring tool holder assembly. The tool for calibrating the precision of the three coordinates is simple and reasonable in structure, easy and convenient to operate, high in calibration precision, and capable of calibrating the precision of the three coordinates at any time to eliminate potential quality hazards, improve product quality, save cost and improve production efficiency.
Description
technical field [0001] The invention relates to the field of calibration tooling, in particular to a calibration tool for three-coordinate precision. Background technique [0002] As a digital and modern scientific and technological measurement equipment, CMM can not only measure dimensions, but also measure position tolerances and geometric shapes, and even complete very complex measurement tasks. [0003] Usually, in the process of using the three-coordinate measuring instrument, we often encounter some troublesome problems: that is, using three-coordinate and other methods to measure the same size, the results obtained are inconsistent. The reason is that the existing three-coordinate equipment has no accessories for verifying the accuracy, and the measurement institute only checks the accuracy once a year, so it is difficult to find out whether the accuracy of the equipment is correct during the use process, and therefore there is a certain hidden error in the detection ...
