Embodiment 1）

[0015] See figure 1 and figure 2 , the carbon fiber composite body component measurement device of this embodiment is composed of a working platform 1, four groups of the same PSD sensor array 2 and a laser emitting assembly.

[0016] Each PSD sensor array 2 is composed of several (400 in this embodiment, 20×20 array) PSD sensors 21 whose photosensitive surfaces are located in the same plane.

[0017] Four sets of identical PSD sensor arrays 2 are arranged on the upper surface of the working platform 1, and the photosensitive surfaces of the four sets of identical PSD sensor arrays 2 and the upper surface of the working platform 1 form a geometric relationship between the four sides and the bottom surface of a cube ( figure 1 The two groups of PSD sensor arrays 2 in front and rear are omitted). Thereby, the relative positional relationship of all PSD sensors 21 on four groups of the same PSD sensor arrays 2 can be determined, denoted as M.

[0018] The laser emitting assem...

Abstract

The invention discloses a carbon fiber composite body component measuring device, which is composed of a working platform, four sets of identical PSD sensor arrays and a laser emitting assembly; the photosensitive surfaces of the four identical PSD sensor arrays are composed of the upper surface of the working platform The geometric relationship between the four sides and the bottom of a cube. The laser emitting component includes a substrate, five lasers and three spheres. The laser axes emitted by the five lasers are located in the same plane, and this plane is parallel to the plane where the triangle formed by the line connecting the centers of the three spheres is located; four of them The lasers are divided into two groups, the laser axes emitted by the two lasers in each group are collinear, and the two lines formed by the two groups of lasers are parallel. The measuring device of the present invention is simple in structure, low in price, has low requirements on operators, and can achieve high measurement accuracy, and can completely replace the measurement of carbon fiber composite body components by a three-coordinate measuring machine.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a measuring device for carbon fiber composite body components. Background technique [0002] The lightweight of the automobile body is of great significance for reducing the energy consumption of the automobile. Especially for pure electric vehicles in new energy vehicles, when the current battery performance is far from satisfactory, it is more practical to reduce the weight of the vehicle body under the premise of ensuring the safety of the vehicle body. The BMW i3 is the first to try this out. The BMW i3, which is not thin in appearance, weighs only 1224kg because of the carbon fiber composite body. [0003] The carbon fiber composite body of the BMW i3 is composed of several carbon fiber composite components. To produce a carbon fiber composite body, several carbon fiber composite components must first be produced, and then all carbon fiber composite c...
