Two-dimensional measurement, the object can show the surface contour of the object and compare it with the set two-dimensional coordinates by using the light projection and the magnifying glass, the measured number is not accurate enough
[0011] The currently used 3D laser measuring machine is also a non-contact fast scanning measurement. Due to the use of laser measuring heads, it is also difficult to accurately measure complex 3D curved surfaces. Not only is the measurement accuracy difficult to guarantee, but also for complex 3D curved surfaces with concave sides can't even do

Embodiment Construction
[0033] See figure 1 The six-axis CNC laser fast three-dimensional measuring instrument shown includes four systems, which are as follows:
[0034] 1) Measuring machine mechanical system:
[0035] It is composed of X, Y, Z three-axis linkage base 2 and measuring table 4 with granite as the main body. Among them, three orthogonal linear motion axes are formed: Y guide rail system is installed under the measuring table 4 to guide the measurement work The table 4 moves back and forth; the beam 6 on the column 5 is equipped with an X-axis guide rail system 7 to move the laser measuring head 11 left and right; the Z-axis guide rail system 9 is installed on the central carriage 8 to guide the laser measuring head 11 installed on the 90 ° The rotating fixture 10 moves up and down; two sets of rotatable precision positioning fixture devices, that is, a set of 360°rotating fixtures 12 are placed on the measuring table 4, which can drive the measured object to rotate 360° in the XY plan...

Abstract
The invention discloses a six-axial numerical-control three-dimensional quick laser measurer which comprises a measurer mechanical system. The measurer mechanical system comprises a measurement operating table, a base and a vertical column portal frame. The measurer is characterized in that the measurer mechanical system further comprises a guide rail system and two groups of rotatable precision positioning clamp devices. The guide rail system comprises an X-direction guide rail system, a Y-direction guide rail system and a Z-directional guide rail system in mutual orthogonality, wherein the X-direction guide rail system is mounted on the measurement operating table, the Y-direction guide rail system is disposed on a movable bridge crossbeam, and the Z-directional guide rail system is mounted in a central sliding frame. The rotatable precision positioning clamp devices are disposed on the measurement operating table and comprises 360-degree rotatable clamps and 90-degree rotatable clamps, wherein the 360-degree rotatable clamps are capable of rotating in a plane of the X and Y directions, and the 90-degree rotatable clamps are mounted in the Z direction and capable of rotating in a plane of the Y and Z directions or a plane of the Z and X directions.
Description
technical field [0001] The invention relates to a measuring instrument, in particular to a six-axis numerical control laser fast three-dimensional measuring instrument. Background technique [0002] Precision workpieces, parts, molds and various product manufacturing industries have been inseparable from testing. As big as automobiles, ships, airplanes, plant structures, components or wholes, as small as circuit boards and electronic components, detectors are used everywhere. Natural or industrially manufactured finished products: no matter metal, non-metal, plastic rubber, silica gel, wood products, glass products, stone products, utensils, paper, leather products, or even tangible objects such as thin films and cotton yarns, as long as you want to know its size , Thickness, length, thickness, shape, etc. have to rely on various measuring tools, gauges, measuring tools, magnifying glasses, projectors, electronic displays and other measuring tools and testing instruments to...
