The angle iron 25 is in threaded connection with the transmission shaft 33, and the angle iron 25 is in threaded connection with the connecting plate 24.
Since the fixed connection of the first component and the transmission shaft 33 is achieved by the angle iron 25, the side surface of the angle iron 25 is a plane, so in this embodiment, the transmission shaft 33 is a cuboid, and thus, the connection of the transmission shaft 33 and the connection plate 24 is facilitated by the angle iron 25. Of course, in other embodiments, the transmission shaft 33 may be a cylinder, and a shaft hole for being disposed with the transmission shaft 33 may be provided on the connection plate 24, through which the connection is made by screws in the radial direction of the transmission shaft 33.

Further, the first assembly further comprises a first inner housing 27 disposed inside the first outer housing 21, the second assembly further comprises a second inner housing 28 disposed inside the second outer housing 22, the first inner housing 27 and the second inner housing 28 are coaxial with the transmission shaft 33, and an annular cavity formed between the first outer housing 21 and the first inner housing 27 and an annular cavity formed between the second outer housing 22 and the second inner housing 28 are used for accommodating cables. Thereby, the regularity of the flexible cable in the annular cavity is ensured.
Correspondingly, in order to avoid interference between the second fixing portion 1202 on the fixing plate 12 and the second inner housing 28, a first avoiding notch is correspondingly arranged on the second inner housing 28 at a position corresponding to the second notch; similarly, in order to avoid interference between the second connection portion 2402 on the connection plate 24 and the first inner case 27, a second avoidance notch is provided on the first inner case 27 at a position corresponding to the first notch.
In the present embodiment, the inner diameter of the first outer housing 21 is equal to the inner diameter of the second outer housing 22, and the outer diameter of the first inner housing 27 is equal to the outer diameter of the second inner housing 28, so that the annular cavity formed by the first outer housing 21 and the first inner housing 27 is kept the same as the annular cavity formed by the second outer housing 22 and the second inner housing 28 in size, and the cable test result is prevented from being affected by the difference in the sizes of the two annular cavities.
According to the cable testing device provided in this embodiment, when a cable needs to be tested, one end of the cable is fixed on the first wire harness fixing clip 26 on the second connecting portion 2402 through the first notch on the first outer housing 21, the other end of the cable is fixed on the second wire harness fixing clip 23 on the second fixing portion 1202 through the second notch on the second outer housing 22, and the intermediate cable is accommodated by the accommodating cavity in the first outer housing 21 and the accommodating cavity in the second outer housing 22.
The first harness fixing clip 26 and the second harness fixing clip 23 may be U-shaped clips as shown in fig. 1, or may be nuts which are fixed by two fixing nuts as shown in fig. 4. In other embodiments, other forms of harness retention clips may be used, as long as clamping of the cable is ensured.
Fig. 4 shows a schematic view of fixing a cable in a cable housing assembly, in fig. 4, two harness fixing clips are provided on a second connection portion 2402, two harness fixing clips are provided on a second fixing portion 1202, and a first harness fixing clip 26 and a second harness fixing clip 23 on the same side on the second connection portion 2402 and the second fixing portion 1202 are used to fix a cable, so that two cables to be tested can be mounted based on the same cable housing assembly.
Fig. 5 shows a schematic view of the cables being fixed in the containing assembly after the first outer case 21, the second outer case 22, the first inner case 27 and the second inner case 28 are hidden, fig. 6 is a schematic view of the rear surface of the cables after the cables are placed in the cable testing device, and as shown in fig. 5 and 6, the cables are fixed at both ends of the cables in the annular containing cavity based on the annular containing cavity defined by the first outer case 21 and the first inner case 27 and the annular containing cavity defined by the second outer case 22 and the second inner case 28, so that the conventional "double-U structure" wiring form in the industrial robot is effectively simulated.
After the two ends of the cable to be tested are respectively fixed at the first wire harness fixing clamp 26 and the second wire harness fixing clamp 23, the transmission shaft 33 drives the first component to rotate, so that the cable to be tested is driven to rotate, specifically, because the second component is kept fixed, the rotation of the cable to be tested is realized by twisting one end of the cable to be tested fixed at the first wire harness fixing clamp 26 relative to one end of the cable to be tested fixed at the second wire harness fixing clamp 23. In the testing process, the rotation range of the first component can be set according to the motion range of the shaft of the industrial robot where the cable to be tested is located, so as to set the rotation range of the motor 32, for example, if the rotation range of one shaft is ±170°, the output rotation range of the driving device can be set to be ±170°, and then under the rotation range, the transmission shaft 33 is controlled to reciprocate alternately, so that the actual operation condition of the cable to be tested is simulated, and the service life of the cable under the operation condition is measured.
In the solution of the present embodiment, since the angle iron 25 is detachably connected with the connecting plate 24, the connecting plate 24 is detachably connected with the first outer housing 21 and the first inner housing 27, and the fixing plate 12 is detachably connected with the second outer housing 22 and the second outer housing 22, so if the wire diameter of the cable to be tested is changed, the testing requirements of the cable with the wire diameter can be met by replacing the first inner housing 27, the second inner housing 28, the first outer housing 21 and the second outer housing 22, and thus, the cable testing device of the present embodiment can be used for testing cables with different wire diameters.
Further, since the detachable connection of the first component to the driving shaft 33 is achieved by the angle iron 25, the fixing plate 12 is detachably connected to the upright 11, and thus, in the cable housing component, the distance between the first component and the second component can be adjusted by adjusting the position of the fixing plate 12 on the upright 11 and/or adjusting the position of the first component on the driving shaft 33. Furthermore, when the length of the cable to be tested is longer, the distance between the first component and the second component can be adjusted to enable the annular cavity formed by the first outer shell 21 and the first inner shell 27 and the annular cavity formed by the second outer shell 22 and the second inner shell 28 to meet the placement requirement of the cable with the corresponding length.
Through the cable testing device of this embodiment, through adjusting the distance between first subassembly and the second subassembly, and changing first shell body 21, second shell body 22, first inner shell body 27, second inner shell body 28 to, can truly simulate the actual installation overall arrangement of cable in the inside of industrial robot, and then guaranteed the validity of the cable test result that obtains based on this cable testing device.
Further, as the plurality of cable containing components are arranged in the cable testing device, a plurality of groups of cables can be tested simultaneously based on the same driving device, the cable testing time is shortened as a whole, and the cable testing efficiency is improved.
