Embodiment 1

[0026] Such as figure 1 with figure 2 Shown, a kind of lightweight measuring instrument comprises measuring arm and the scanning head 6 that is fixed on the free end of measuring arm, and described measuring arm comprises the first measuring arm 2, the second measuring arm 4 and the 3rd measuring arm 5, so 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 hingedly connected to the third measuring arm 5 through a hinge 3. 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, the hinge axes of the two hinge parts 3 are parallel to each other, and the fixed seat 1 is in the shape of a flange , the upper end surface of the fixed seat 1 is provided with a bearing connection part 11 for connecting the fixed seat 1 and the first measuring arm 2, and the fix...

Embodiment 2

[0032] The present embodiment is further limited on the basis of embodiment 1, as figure 1 with figure 2 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.

[0033] 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.

[0034] In order to make the parts of the device have a higher connection strength, and at the same ...

Embodiment 3

[0036] 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 light measurement instrument, which comprises measurement arms and a scanning head, wherein the measurement arms comprise a first measurement arm, a second measurement arm and a third measurement arm; any end of the first measurement arm and any end of the second measurement arm are hinged and connected via a hinging part; the other end of the second measurement arm and the third measurement arm are hinged and connected via a hinging part; the scanning head is fixed at the free end of the third measurement arm; the free end of the first measurement arm is also provided with a fixing seat; the fixing seat is in a shape of a flange plate; the fixing seat is provided with a bearing connection part, multiple bolt holes and inner threaded holes; each of the first measurement arm, the second measurement arm and the third measurement arm has a multi-section combination structure; and the first measurement arm, the second measurement arm and the third measurement arm are all provided with temperature sensors. The light measurement instrument is applicable to field measurement, is particularly applicable to three-coordinate measurement of a heavy measured object, and is light in structure, convenient in mounting and high in measurement precision.

Description

technical field [0001] The invention relates to the field of dimension measuring equipment, in particular to a lightweight measuring instrument. 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 for complex measurement tasks from hours to m...
