Embodiment 1

[0020] Such as figure 1 As shown, a measuring device for improving the multi-dimensional accuracy of finishing includes a measuring arm and a scanning head 6 fixed on the free end of the measuring arm, and the measuring arm includes a first measuring arm 2, a second measuring arm 4 and a third measuring arm. Measuring arm 5, any one end of the first measuring arm 2 is hingedly connected to any one end of the second measuring arm 4 through a hinge 3, and the other end of the second measuring arm 4 is connected to the third measuring arm 5 through a hinge 3 Hingedly connected, the scanning head 6 is fixed on the free end of the third measuring arm 5, the free end of the first measuring arm 2 is also provided with a fixed seat 1, and the hinge axes of the two hinge parts 3 are parallel to each other;

[0021] The first measuring arm 2 , the second measuring arm 4 and the third measuring arm 5 are all provided with temperature sensors, and the output terminals of each temperature ...

Embodiment 2

[0025] The present embodiment is further limited on the basis of embodiment 1, as figure 1 As shown, in order to facilitate the rotation of the braking scanning head 6 relative to the third measuring arm 5, so that the mechanism can more flexibly complete point and surface scanning, the third measuring arm 5 and the scanning head 6 pass through a hinge 3 are hingedly connected, and the hinge axes of the three hinge parts 3 are parallel to each other.

[0026] As a way to realize a measuring arm with light weight, high specific strength, and small coefficient of thermal sensitivity, the materials at both ends of the first measuring arm 2, the second measuring arm 4 and the third measuring arm 5 are made of titanium alloy. The materials between the two ends of the first measuring arm 2 , the second measuring arm 4 and the third measuring arm 5 are carbon fibers.

[0027] In order to make the parts of the device have a higher connection strength, and at the same time facilitate ...

Embodiment 3

[0029] This embodiment is further limited on the basis of any one of the solutions provided in the above embodiments. In order to facilitate the scanning efficiency of the device, the number of scanning heads 6 fixed on the free end of the third measuring arm 5 is more than one or the type is more than one .

Abstract

The invention discloses a measuring device for improving the multi-dimensional precision of finishing, which comprises a measuring arm and a scanning head fixed on the free end of the measuring arm, and the measuring arm includes a first measuring arm, a second measuring arm and a third measuring arm , any one end of the first measuring arm is hingedly connected to any one end of the second measuring arm through a hinge, the other end of the second measuring arm is hingedly connected to the third measuring arm through a hinge, and the scanning head is fixed on the third On the free end of the measuring arm, a fixed seat is also arranged on the free end of the first measuring arm, and the hinge axes of the two hinge parts are parallel to each other; the first measuring arm, the second measuring arm and the third measuring arm are all provided with There is a temperature sensor. The invention has light structure and high measurement precision, and is especially suitable for three-coordinate measurement of bulky measured objects.

Description

technical field [0001] The invention relates to the field of dimension measuring equipment, in particular to a measuring device for improving the multi-dimensional precision of finishing. Background technique [0002] Three-coordinate measuring machines are mainly used for boxes, racks, gears, cams, worm gears, worms, blades, curves, and curved surfaces in industries such as machinery, automobiles, aviation, military industry, furniture, tool prototypes, machines and other small and medium-sized accessories, molds, etc. It can also be used in electronics, hardware, plastics and other industries to precisely detect the size, shape and shape tolerance of the workpiece, so as to complete parts detection, shape measurement, process control and other tasks. Three-coordinate measurement is one of the most efficient ways to measure and obtain dimensional data, because it can replace multiple surface measurement tools and expensive combination gauges, and reduce the time required fo...
