Embodiment
A kind of whip shape lock bending strength test platform; Comprise workbench 1; Be vertically set on the back up pad 2 on the workbench 1, on described back up pad 2, with bolt displacement transducer mounting bracket 3 and motor mounting rack 5 arranged, displacement transducer mounting bracket 3 is positioned at the lower end of motor mounting rack 5; Displacement transducer 4 one ends are fixed on the electric machine support 5, and the other end is fixed on the displacement transducer mounting bracket 3; Push-rod electric machine 6 is fixed on the motor mounting rack 5.Wherein the push rod end of the mobile terminal of displacement transducer 4 and push-rod electric machine 6 all is fixed on and is connected on the top board 7; Connect top board 7 lower ends and be provided with force transducer 8; The lower end of force transducer 8 is provided with force transducer push rod 9, and force transducer push rod 9 is fixedly connected with Clamping Apparatus of Connecting Rod 10, and Clamping Apparatus of Connecting Rod 10 is used for fixing whip shape lock connecting rod 13; In work flat 1, also be provided with dead bolt end stationary fixture 11, be used for fixing whip shape lock dead bolt 12.
Described Clamping Apparatus of Connecting Rod 10 comprises rotating part 101, the clamping part 102 that is slidingly connected with rotating part 101; Be provided with the fixedly bolt hole of whip shape lock connecting rod 13 at described clamping part 102 upper and lower ends.Described rotating part 101 lower ends are provided with guide groove 1011, and clamping part 102 is provided with the guide rod 1021 adaptive with guide groove 1011, and guide rod 1021 can slide along guide groove 1011 front and back.Described dead bolt end stationary fixture 11 comprises the fixed clamp portion that is fixed on the workbench 1 111 and dismountable adjusting clamping part 112, and fixed clamp portion 111 and regulating forms the cavity suitable with dead bolt 12 between the clamping part 112; Fixed clamp portion 111 with regulate clamping part 112 and be connected through bolt.
