Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] Such as image 3 As shown, the device for accurately measuring the micro-deformation of a space-use composite material bar according to the present invention consists of a steel ball 1 and a direct head 2 . The direct head 2 adopts a hollow structure design, and adopts mechanical integration processing and molding, such as figure 1 As shown, a first cylindrical structure 4 and a second cylindrical structure 5 are respectively arranged at both ends of the direct head 2, and a square structure 6 is arranged in the middle, the first cylindrical structure 4 cooperates with the steel ball 1, and the second cylindrical structure 5 cooperates with the composite material bar 3. Such as figure 2 As shown, a through hole 7 is provided on the first cylindrical structure 4 close to the radial direction of the square structure 6, and a spherical groove 9 is pro...
