Embodiment 1

[0018] Such as figure 1 As shown, a machine tool measurement method for improving calibration efficiency includes a measurement arm and a scanning head 6 fixed on the free end of the measurement arm. The measurement arm includes a first measurement arm 2, a second measurement arm 4 and a third measurement 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, and the free end of the first measuring arm 2 is also provided with a fixing base 1, and the hinge axes of the two hinge parts 3 are parallel to each other.

[0019] In this embodiment, the fixed seat 1 provided is used for fixing the structure next to the workpiece or parts, by setting the measuring arms as multiple, that is, the...

Embodiment 2

[0021] 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.

[0022] 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.

[0023] In order to make the parts of the device have a higher connection strength, and at the same time facilitate ...

Embodiment 3

[0025] 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 machine tool measurement method for improving calibration efficiency, which comprises a measurement arm and a scanning head fixed on the free end of the measurement art, wherein the measurement arm comprises a first measurement arm, a second measurement arm and a third measurement arm; any end of the first measurement arm is hinged with any end of the second measurement arm through a hinge part; the other end of the second measurement arm is hinged with the third measurement arm through a hinge part; the scanning head is fixed on the free end of the third measurement arm; the free end of the first measurement arm is also provided with a fixing seat; and the hinge shafts of the two hinge parts are mutually parallel. The structure is light and convenient and the method is particularly suitable for three-coordinate measurement on a heavy measured object.

Description

technical field [0001] The invention relates to the field of dimension measuring equipment, in particular to a machine tool measuring method for improving calibration efficiency. 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...
