then, a distortion test is carried out, firstly, the first electric telescopic rod 21 is driven, so that the first movable clamping plate 20 moves towards one end far away from the first fixed clamping plate 19, at this time, the first movable clamping plate 20 and the first fixed clamping plate 19 do not fix the plastic column 9 any more, at this time, the movement of the first electric telescopic rod 21 enables the position of the shifting block 22 to shift the limiting rod 23, the plastic column 9 is inserted into the fixed sleeve 29 and extends into the rotating disc 27, the third electric telescopic rod 38 is driven to work to further drive the second movable clamping plate 37 to move towards one end close to the second fixed clamping plate 36, at this time, one end of the plastic column 9 can be fixed due to the clamping effect of the second fixed clamping plate 36 and the second movable clamping plate 37, when the bolt is unscrewed, the first cross rod 6 is not fixed with the second cross rod 7, at this time, when the driving motor 25 works clockwise, the clamping plate 28 is clamped with the fixed sleeve 29 when starting, the rotating disc 27 can be driven to rotate together, so that the rotating disc 27 drives the plastic column 9 to perform torsional motion, when the clamping plate 28 rotates and is close to the shifting block 22, the limiting rod 23 is shifted by the shifting block 22, the clamping plate 28 moves towards one end far away from the rotating disc 27 and is not separated from the interior of the clamping groove 41, at the moment, the second movable clamping plate 37 moves towards one end far away from the second fixed clamping plate 36, so that the clamping on the plastic column 9 is loosened, the plastic column 9 can be automatically reset after being twisted, when the plastic column 9 passes through the shifting block 22, the second movable clamping plate 37 can be reset again under the elastic force action of the spring 39, and thus the multi-time torsion test process can be realized;
when the bolt is not screwed out, the first cross rod 6 and the second cross rod 7 are fixed and can further drive the movable plate 8 to reciprocate in the first slide rail 16, so that the plastic column 9 can be subjected to a tensile test under the reciprocating action of the movable plate 8, and a torsion test can be completed at the same time, thereby facilitating the comprehensive test of performance of the plastic column 9 under the dual actions of tensile and torsion;
when the test is finished, the plastic column 9 can be subjected to a second impact test, and the change condition of the strength of the plastic column 9 after the test can be further analyzed by collecting and comparing the first impact and the second impact.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
