[0029] As Figure 1 , Figure 2 , Figure 3 And Figure 4 Indicated, a multi-purpose cable testing mechanism, including workbench 1, the middle position of the workbench 1 is provided with a work groove 2, the lower side rotary motor 3 is installed correspondingly in the work groove 2, the main shaft of the lower side rotary motor 3 is stretched upwards, and the shaft end is correspondingly installed with the lower pressing plate 4, and the height of the lower pressing plate 4 is consistent with the height of the workbench 1.

[0030] The upper portion of the workbench 1 is also provided with a lifting mechanism 5, the main shaft of the lifting mechanism 5 is stretched downwards, and the shaft end is correspondingly installed with the lifting plate 6, and the lower end surface of the lifting plate 6 is installed with the upper side rotary motor 7, the main shaft of the upper side rotary motor 7 is stretched downwards, and the shaft end is correspondingly installed with the upper pressing plate 8.

[0031] The position of the upper side rotary motor 7 and the lower side rotary motor 3 corresponds, so that the position of the upper pressing plate 8 corresponds with the position of the lower pressing plate 4, the cable 9 is placed on the workbench 1 and the lower pressing plate 4, the lifting mechanism 5 at the upper portion drives the lifting plate 6 and the rotary mechanism at the lower portion to move downwards, so that the upper pressing plate 8 presses the lower pressing plate 4, and the cable 9 is extruded, and then the cable 9 is powered on for testing, realizing the power-on test of the cable 9 under extrusion.

[0032] The lower pressing plate 4 is also provided with a limiting hole 10, and the lower end surface of the upper pressing plate 8 is provided with a limiting rod 11 corresponding to the position of the limiting hole 10.

[0033] The position of the limiting rod 11 corresponds with the position of the limiting hole 10 by adjusting the position of the upper pressing plate 8 and the lower pressing plate 4 through the upper side rotary motor 7 and the lower side rotary motor 3, so that when the limiting rod 11 corresponds with the limiting hole 10, the lower pressing plate 4 moves downwards, and the limiting rod 11 is inserted into the limiting hole 10.

[0034] The limiting hole 10 on the lower pressing plate 4 is arranged at the edge position of the plate body, the position of the limiting rod 11 installed on the upper pressing plate 8 corresponds with the position of the limiting hole 10, and the bottom of the limiting rod 11 is in the shape of a sharp end.

[0035] The limiting hole 10 is provided with two symmetrical groups on the lower pressing plate 4, and each group is provided with three hole bodies, and the position of the limiting hole 10 is arranged without hindering the placement of the cable 9.

[0036] The workbench 1 is provided with a positioning groove 14 for placing the cable 9.

[0037] The lower end of the main shaft of the downward pressing mechanism 12 extends upward and is provided with a positioning seat 13, and the lower end surface of the positioning seat 13 is provided with a positioning groove 14 corresponding to the position of the positioning groove 14 on the lower workbench 1. When the positioning seat 13 is moved downward by the downward pressing mechanism 12, the upper and lower positioning grooves 14 are connected.

[0038] The positioning groove 14 is a semicircular groove structure, and the upper and lower positioning grooves 14 form a whole circular groove structure. The cable 9 is placed in the circular groove structure, and the inner diameter of the circular groove structure is larger than the outer diameter of the cable 9, so that the cable 9 can move freely left and right in the positioning groove 14.

[0039] The specific working process of the device is as follows: the cable to be tested is placed on the workbench, and the positioning groove is provided on the workbench. The cable is placed in the positioning groove, and the height of the lower pressing plate is consistent with the height of the workbench. Therefore, the cable is placed on the workbench, and the lower side rotating mechanism needs to be controlled to adjust the position of the lower pressing plate, so that the placement of the cable does not interfere with the position of the limiting hole. The position of the upper side rotating mechanism is adjusted correspondingly, so that the position of the limiting rod on the upper pressing plate corresponds to the position of the limiting hole.

[0040] Then the lifting mechanism is controlled to move the lifting plate downward, and the lifting plate moves the upper pressing plate downward correspondingly. The limiting rod on the lower pressing plate passes through the limiting hole and continues to move downward, and then the cable placed on the upper pressing plate is extruded. Then the cable is energized for testing, and the cable can be tested under extrusion. The pressure of the lifting mechanism can be adjusted to adjust the extrusion force.

[0041] The device can not only complete the extrusion test of the cable, but also complete the bending and twisting test of the cable. When the limiting rod extends into the limiting hole of the lower pressing plate after the upper pressing plate moves downward, the upper side rotating mechanism and the lower side rotating mechanism are started to rotate synchronously. Since the cable is limited by the moving rod between the upper pressing plate and the lower pressing plate, when the lower pressing plate and the upper pressing plate rotate, the cable can be rotated, bent and twisted. Then the test is completed by energization, so as to realize the bending and twisting test of the cable.

[0042] Of course, the device can also extrude and start the upper and lower rotating mechanisms to drive the cable to bend and twist, so as to realize the test of the cable under the conditions of extrusion, bending and twisting.

[0043] And in the above process, since the cable will produce displacement when being bent, the device is provided with a pressing mechanism and a positioning seat at the positions of the two sides of the workbench, and the positioning seat is also provided with a positioning groove, and in the specific bending and twisting, the positioning seat is driven to move downward by the pressing mechanism, so as to position and limit the cable in the positioning groove, so that when the cable is twisted, the cable can only move in the positioning groove, and the position of the cable is determined, so that the cable cannot move randomly, and the subsequent power-on test of the cable is facilitated, and the structure is reasonable and ingenious.

[0044] The above specific embodiment is only a preferred embodiment of the utility model, and is not used to limit the implementation and the scope of claims of the utility model, and equivalent changes and modifications made according to the patent protection scope of the utility model should be included in the patent application scope of the utility model.
