Abstract

The invention discloses a chord tightening constant-tension loading device of a flexible frame. The problem of unstable chord tension caused by flexible frame deformation is solved by utilizing the principle that the deformation is applied in advance. The chord tightening constant-tension loading device of the flexible frame mainly consists of a tensile force application device and a counter forceapplication device, wherein the tensile force application device is composed of a high-precision linear module, a three-pulley type tension sensor, an electromagnetic brake, an electromagnetic clutchand a synchronous wheel; and the counter force application device is composed of a supporting frame, a guide rail, a sliding block, a fixed pulley, a movable pulley and an angle rod. Firstly, chord installation is carried out on the tensile force application device and the counter force application device according to a chord tightening principle diagram to mainly solve the problem of unstable chord tension caused by flexible frame deformation; and then the tensile force loading work is carried out, and stable loading and timely control of tension are realized by utilizing the module and thethree-pulley type tension sensor; and finally the final tension of a chord is maintained by utilizing the electromagnetic brake and the clutch.

Description

technical field [0001] The invention relates to constant tension loading of strings on a flexible frame. By using a tension applying device, tension can be applied to each string on the opposite side of the flexible frame to make it tight. When the specified tension is reached and the strings are fixed, the strings The tension value above remains unchanged, which can achieve high control precision and good stability, and belongs to the field of mechanical technology. Background technique [0002] In order to meet the requirements of the subsequent assembly and action state of the flexible frame, the requirements for the dimension accuracy and shape accuracy of the flexible frame are relatively high. At the same time, in order to ensure the normal working state, the tension values ​​of the strings on the flexible frame must be consistent. Therefore, there is a need for a tension applying device that can realize constant tension loading on the strings on the flexible frame. S...
