description of reference numerals: the device comprises a test bed 1, a cable guide plate 1-1, a semicircular sleeve 1-2, an electric push rod 2, a driving motor 2-1, a push rod 2-2, a controller 3, a push rod motor rotating support 4, bolt holes 4-1, a hoop 5, a cable 6 and a rotating shaft 7.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments, and the objects and effects of the present invention will become more apparent, and the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1 to 4, the cable bending test device of the present invention includes a test bed 1, an electric push rod 2, a controller 3, a push rod motor rotating bracket 4, a hoop 5, a cable 6 and a rotating shaft 7.

The test bed 1 is fixedly connected with a cable guide plate 1-1 and a semicircular sleeve 1-2, and the cable guide plate 1-1 is used for fixing the bending radius of a cable 6. The cable guide plates 1-1 of different radii can be replaced for different cables. The rotating shaft 7 is fixed on the test bed 1, the push rod motor rotating support 4 is hinged with the rotating shaft 7, the electric push rod 2 comprises a driving motor 2-1 and a push rod 2-2, one end of the driving motor 2-1 is fixedly connected with the push rod motor rotating support 4, and one end of the push rod 2-2 is rotatably connected with the hoop 5. The controller 3 is fixed on the test bed 1 through a sucker, a magnet or a bolt and is connected with the driving motor 2-1 through a lead. The controller 3 is provided with a start-stop button for controlling the start-stop of the driving motor 2-1; the controller 3 may also implement functions such as reset, count, etc.

During testing, one end of a cable to be tested penetrates through a semicircular sleeve 1-2 fixed on a test bed 1, and the other end of the cable penetrates through a hoop 5; the starting of the driving motor 2-1 is controlled through a starting button on the controller 3, so that the push rod 2-2 is retracted, the cable 6 to be tested is driven to bend, and the tightening state is realized. When the push rod 2-2 acts, the electric push rod 2 and the motor rotating bracket 4 can slightly rotate around the rotating shaft 7 due to the reaction force of the cable, so that the movement of the electric push rod 2 is smoother, and the blockage is prevented. The cable bending radius is a fixed value in the tightened state, and the service life of the cable is effectively prolonged within a safe range. And the reset button of the controller 3 is pressed again, the driving motor 2-1 pushes the push rod 2-2 to extend out, and the push rod 2-2 drives the cable 6 to recover to realize a loosening state. The cable both ends are equipped with cable break-make test module, can observe the break-make condition of the inside heart yearn of cable in real time to judge the bending life-span of cable.

Therefore, the cable bending test device can control the range of the cable bending tolerance on the premise of not damaging the cable, and has the advantages of simple structure and convenient operation.
