Problems solved by technology

For many years, the loading head has been used to simulate the working state of the balance in balance calibration and loading to obtain the formula of the balance. According to the size of the calibration load, the structure of the loading point has top type, universal joint type, straight knife-edge type, elastic Hinged type, in which the elastic hinge has the advantages of no mechanical friction, reliable operation, can withstand positive or negative loads, and is easy to realize two-way degrees of freedom, etc., but the traditional elastic hinge structure is fragile, and improper storage and installation will cause bending damage. There is also the disadvantage of sudden breakage and damage to the sensor during use

Embodiment 1

[0019] to combine Figure 1-4 As shown, an elastic hinge with multiple protection functions for a balance calibration system includes a hinge 1, the hinge 1 is provided with a limiting component, and the limiting component includes a limiting body 2 and a limiting groove 3, The limiting body 3 is designed as a V-shaped hook, and the V-shaped hook part of the limiting body 3 is located in the limiting groove 3. The bottom of the V-shaped hook of the limiting body 3 extends downward and is fixedly connected with the hinge 1. The width of the opening of the limiting groove 3 is smaller than the diameter of the V-shaped hook of the limiting body 3, and the limiting body 2 and the limiting groove 3 cooperate with each other to realize structural limitation and fracture protection.

[0020] The hinge 1 described in this embodiment is a cylindrical one-piece structure.

[0021] There is a gap between the limiting body 2 and the limiting groove 3 described in this embodiment.

Abstract

An elastic hinge with multiple protection functions and used for a balance calibration system comprises a hinge. A limiting component is arranged on the hinge and comprises a limiting part and a limiting groove, the limiting part is in a V-shaped hook design, a V-shaped hook of the limiting part is partially positioned in the limiting groove, and the bottom of the V-shaped hook extends downwards to be fixedly connected with the hinge. The width of an opening of the limiting groove is smaller than the diameter of the V-shaped hook of the limiting part, and the limiting part and the limiting groove are matched with each other to realize structural limiting and fracture protection. The elastic hinge in an integral structure has the protection functions of fracture protection and mechanical limiting protection and has advantages of simplicity in processing, high mounting positioning performance and the like.

Description

technical field [0001] The invention relates to an elastic hinge with multiple protection functions for a balance calibration system. technical background [0002] The wind tunnel balance is one of the key equipments in the wind tunnel force test, and the accuracy of the balance directly affects the accuracy of the wind tunnel test data. The balance is a measuring instrument, and it cannot be used without calibration. The calibration of the balance is completed through the balance calibration system, and the loading head is an important part of the balance calibration system. The loading point is one of the key parts of the loading head, which acts as a calibration load. The functions of transmission, positioning and interference elimination. For many years, the loading head has been used to simulate the working state of the balance in balance calibration and loading to obtain the formula of the balance. According to the size of the calibration load, the structure of the lo...
