Embodiment 1

[0023] like figure 1 As shown, a coordinate measuring system for machining blanking process includes a measuring arm and a scanning head 6 fixed on the free end of the measuring arm, the measuring arm includes a first measuring arm 2, a second measuring arm 4 and The third measurement arm 5, any end of the first measurement arm 2 and any end of the second measurement arm 4 are hingedly connected through a hinge part 3, and the other end of the second measurement arm 4 and the third measurement arm 5 are hinged through a hinge The parts 3 are 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 fixing seat 1, and the hinge axes of the two hinge parts 3 are parallel to each other;

[0024] The first measurement arm 2, the second measurement arm 4 and the third measurement arm 5 are all multi-section combined structures, and the multi-section combined structures all include...

Embodiment 2

[0030] This embodiment is further limited on the basis of Embodiment 1, such as figure 1 As shown, in order to facilitate the rotation of the scanning head 6 relative to the third measuring arm 5, so as to make the mechanism more dexterous to complete point and surface scanning, the third measuring arm 5 and the scanning head 6 pass through a hinge 3 Hinged connection, and the hinge axes of the three hinge parts 3 are parallel to each other.

[0031] As an implementation of the measuring arm with light weight, high specific strength and small thermal sensitivity coefficient, the material of both ends of the first measuring arm 2, the second measuring arm 4 and the third measuring arm 5 is made of titanium alloy , the parts between the two ends of the first measurement arm 2 , the second measurement arm 4 and the third measurement arm 5 are made of carbon fiber.

[0032] In order to have a high connection strength between the components of the device, and at the same time, it ...

Embodiment 3

[0034] 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 or type of scanning heads 6 fixed on the free end of the third measurement arm 5 is more than one or more than one type. .

Abstract

The invention discloses a coordinate measuring system used in machining and blanking process, which comprises a measuring arm and a scanning head fixed on the free end of the measuring arm. The measuring arm includes a first measuring arm, a second measuring arm and a third measuring arm. A 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 On the free end of the third 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 It is a multi-section combined structure; the first measuring arm, the second measuring arm and the third measuring arm are all equipped with temperature sensors. The invention has a light structure, is easy to carry or transport, has high measurement accuracy, and is especially suitable for three-coordinate measurement of bulky objects to be measured.

Description

technical field [0001] The invention relates to the field of dimension measuring equipment, in particular to a coordinate measuring system for machining blanking process. Background technique [0002] The CMM is mainly used for boxes, racks, gears, cams, worm gears, worms, blades, curves, curved surfaces in machinery, automobiles, aviation, military industry, furniture, tool prototypes, machinery and other small and medium-sized accessories, molds and other industries. It can also be used in electronics, hardware, plastics and other industries to accurately detect the size, shape and geometric tolerance of the workpiece, so as to complete tasks such as parts detection, shape measurement, and process control. CMM is one of the most effective 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 minutes. The function of th...
