To ensure the stability of the cables, it is necessary to simulate different environments and the different possible torsion of the cables before putting them into use, so as to test the stability of the cables under extreme usage conditions.

A set of locking modules 32 is respectively installed on the rotating table 1 214 and the rotating table 2 244; the clamping module 31 for clamping the cable 4 is installed in the locking module 32; The locking module 32 includes a fastening mounting platform 321 and a locking pin 324. A fastening mounting platform 321 is mounted on the rotating platform 1 214 and the rotating platform 2 244, respectively. The fastening mounting platform 321 is provided with a mounting slot 322 for mounting the clamping module 31. The fastening mounting platform 321 is symmetrically provided with a plurality of locking slots 323, and the locking pins 324 are plugged into the locking slots 323. The clamping module 31 includes a conformable fastening plate 311, an elastic clamping plate 313, and a limit assembly plate 314. Two conformable fastening plates 311 are provided, and the two conformable fastening plates 311 are fastened by symmetrical bolts. A conformable groove 312 is provided in the middle of the conformable fastening plate 311, and the two conformable grooves 312 form a circular groove for accommodating the cable 4.

[0026] In this embodiment, when the composite torsion test mechanism 2 and the separate fixing mechanism 3 are working normally, on the outside of the high and low temperature test chamber 1, the end of the cable 4 is passed through the conformal groove 312 on the inner side of the two conformal fastening plates 311; then the two conformal fastening plates 311 are fastened by bolts, and the cable 4 is clamped by the elastic clamping plates 313 on the inner sides of the two conformal grooves 312; then the conformal fastening plate 311 and the limit combination plate 314 connected to the lower end of the cable 4 are inserted into the mounting groove 322 of the fastening mounting platform 321 on the rotating platform 214. , insert the conformable fastening plate 311 and the limiting assembly plate 314 connected to the upper end of the cable 4 into the mounting groove 322 of the fastening mounting platform 321 located on the second rotating platform 244; align the locking slot 323 on the fastening mounting platform 321 with the locking slot 323 on the limiting assembly plate 314, and then pass the locking pin 324 through the locking slot 323 on the fastening mounting platform 321 and the locking slot 323 on the limiting assembly plate 314 to complete the locking of the conformable fastening plate 311 and the limiting assembly plate 314; thereby completing the installation of the cable 4; During use, when the high and low temperature test chamber 1 is being tested, both ends of the cable 4 can be fastened on the outside by another set of conformal fastening plates 311; and after the cable 4 in the high and low temperature test chamber 1 is tested, the external cable 4 can be quickly installed in the high and low temperature test chamber 1 by using the conformal fastening plates 311 and the limit assembly plates 314. During the test, the linear module 261 drives the movable support platform 262 and the elastic pad 263 to move to the bottom of the high and low temperature test chamber 1. At this time, the elastic pad 263 does not support the movable mounting platform 212. At this time, the movable mounting platform 212 synchronizes with the traction of the cable 4 to maintain balance, thereby making the cable 4 taut. The linear module 261 drives the elastic pad 263 upward through the movable support platform 262, and supports the movable mounting platform 212 through the elastic pad 263. At this time, the movable mounting platform 212 and the counterweight 222 on the movable mounting platform 212 are supported by the elastic pad 263, thereby relaxing the cable 4. This allows the cable 4 to undergo torsion testing in both taut and relaxed states. The rotating cylinder 1 213 drives the rotating table 1 214 to rotate, thereby driving the lower side of the cable 4 to twist through the fastening mounting platform 321, the locking pin 324, the conformal fastening plate 311 and the limit assembly plate 314; the rotating cylinder 243 drives the rotating table 2 244 to rotate, thereby driving the upper end of the cable 4 to twist through the fastening mounting platform 321, the locking pin 324, the conformal fastening plate 311 and the limit assembly plate 314; after a period of experimentation, the cable 4 can be driven to rotate together by a certain angle, thereby changing the bending direction when continuing the test; the two ends of the cable 4 can be rotated in opposite directions to cause the cable 4 to twist; The rotating motor 231 drives the rotating mounting plate 232 to rotate, thereby driving the cam rotating platform 234 to rotate through the limiting rod 233; the rotation of the cam rotating platform 234 causes the cable 4 to bend to one side; when the elastic pad 263 supports the movable mounting platform 212, the two sets of cam rotating platforms 234 can respectively bend the middle portion of the cable 4 in different directions, thereby achieving support for the middle portion of the cable 4; The swing motor 241 drives the swing arm 242 to rotate, and the swing arm 242 drives the conformal fastening plate 311 and the upper end of the cable 4 to rotate through the fastening mounting platform 321 and the locking pin 324 on the rotating platform 244; the upper side of the cable 4 is moved from a straight state to approach the arc-shaped support plate 252, and the cable 4 is supported by the arc-shaped support plate 252, thereby driving the lower side of the cable 4 to move upward; cooperate with the gravity of the movable mounting platform 212 and the counterweight block 222 to make the cable 4 bend under the load state.
