Vertical calibration device for coordinate measuring machine

Abstract

The invention discloses a vertical calibration device for a coordinate measuring machine. The vertical calibration device comprises an upright supporting rod which is used for fixing the device on the measuring platform of the coordinate measuring machine and a detachable contact tester which is arranged at the top end of the supporting rod. A male thread section is formed at the bottom end of the supporting rod. The contact tester comprises a main body, a contact switch circuit which is arranged in the main body, a measuring instrument which is arranged above the main body, and a contact probe which feeds back a signal to the contact switch circuit through the position change of the contact probe and displays a numeric value on the measuring instrument, wherein the contact probe is elastically, recoverably and rotatably connected with the main body. The vertical calibration device for the coordinate measuring machine has the beneficial effects that the structure is simple, the cost is low, the device is convenient to use and the vertical calibration efficiency is greatly improved.

Description

technical field [0001] The invention relates to a horizontal calibration device, in particular to a device suitable for vertical calibration of a three-coordinate tester. Background technique [0002] Coordinate Measuring Machine (CMM) refers to an instrument capable of measuring geometric shape, length, and circumference indexing within a hexahedral space. It is also called a coordinate measuring machine or a three-dimensional dimension. Therefore, the three-coordinate measuring instrument is a very precise instrument, and it needs the corresponding measurement software and debugging to realize its proper function. [0003] After the assembly of the current three-coordinate measuring instrument is completed, it is necessary to calibrate its executive parts corresponding to the three axes of the Cartesian coordinate system to ensure the accuracy of its operation in all directions. In the past, the calibration of its operation in the vertical direction It is calibrated by th...

[0003] After the assembly of the current three-coordinate measuring instrument is completed, it is necessary to calibrate its executive parts corresponding to the three axes of the Cartesian coordinate system to ensure the accuracy of its operation in all directions. In the past, the calibration of its operation in the vertical direction It is calibrated by the articulated arm three-coordinates instrument. The defect is that the calibration accuracy of the articulated arm three-coordinates instrument itself will affect the calibration. The cost of the articulated arm three-coordinates instrument is relatively high. It is purchased for one adjustment. , which greatly increases the cost, the operation of the articulated arm three-coordinate instrument is complicated, and the calibration requires professionals to achieve
