Description

Cable bending test machine suitable for cables of multiple specifications

Technical Field

The utility model relates to a cable test technical field, in particular to cable test machine of bending that is suitable for many specifications cable.

Background

The cable is a conductive component with certain flexibility and pipe diameter, and generally consists of an inner conductive core body and an outer insulating protective sleeve. The cable needs to be capable of connecting two interfaces with different directions, so the bending state is the normal state in the use of the cable, on one hand, the conductive core cannot be easily broken to cause an open circuit in the use process, and on the other hand, the protective sleeve cannot be broken when bent at a large angle to cause the conductive part to be exposed outside, so before the cable is sold, the bending resistance of the cable needs to be detected.

The bending detection of the cable needs to carry out a large amount of reciprocating bending on the cable to represent the bending resistance, and the bending detection needs to be completed through a cable bending tester. The working principle is that the middle section of the cable is fixed, then the tail end of the cable is fixed on a rocker arm, and the rocker arm is reciprocated to test. The outer diameter of the cable can be changed according to different specifications, so that the rigidity of the cable is different, the bending resistance force of the thicker cable is larger, and the cable can be bent and fixed if the moment is too large, so that the detection cannot be carried out.

It is therefore necessary to provide a new device structure to solve the above problems.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 and 2, a cable bending tester suitable for cables of multiple specifications includes a rack 1, a cable clamping mechanism 2 located on the front of the rack 1, and a swing mechanism 3 located above the cable clamping mechanism 2, where the swing mechanism 3 includes a swing arm 31 connected to the rack 1 by a horizontal shaft, a driving device for enabling the swing arm 31 to swing back and forth, and a cable port fixing device 32 located at the outer end of the swing arm 31, a long sliding hole 311 is formed in the swing arm 31 along the length direction, a cantilever 31 parallel to the swing shaft is movably fixed in the long sliding hole 311, and a plurality of fixing points 322 facing the swing shaft are arranged on the cantilever 31 side by side. During the test, the end of cable is fixed in on fixed point 322, and the centre gripping of cable middle part is in the centre of two splint 2, starts the machine, and swing arm 31 will take some of cable to carry out the swing back and forth according to the condition of setting for, and the condition of setting for includes swing angle, swing number of times etc. bending of cable just so can go on automatically, and after the swing was accomplished, the cable just can carry out relevant electrically conductive detection, just so can conveniently characterize the resistant bending nature of cable. When the cable is relatively thick and hard, the distance between the cantilever 31 and the swing shaft can be adjusted along the sliding long hole 311 on the swing arm 31 to the direction close to the swing shaft, so that the moment can be reduced, and the bending can be finished.

As shown in fig. 1, the cable clamping mechanism 2 includes a pair of vertically disposed clamp plates 21 and a pair of equally-high pressure rollers 22, the pressure rollers 22 are located above the clamp plates 21, and the swing arms 31 use the symmetry axis of the pressure rollers 22 as the swing center line. When the cable bends to the limit, the cable can be attached to the surface of the pressing roller 22, namely the radius of curvature of the cable when bending is not smaller than that of the pressing roller 22, so that direct tearing of the cable caused by excessive bending is avoided, and detection can be continued.

As shown in fig. 1, a pair of slide rails 11 is horizontally disposed on the front surface of the rack 1, and the two clamp plates 21 can move toward or away from each other along the slide rails 11. The clamping plates 21 are used for preventing the cable from jumping randomly during the back-and-forth bending process to cause unstable state, so that the gap between the two clamping plates 21 needs to be adjusted to realize better clamping.

As shown in fig. 1, a screw fixing pin 211 is further inserted into the clamping plate 21, and the screw fixing pin 211 can abut against the slide rail 11 to disable the clamping plate 21 from moving. The screw fixing pin 211 can fix the position of the clamping plate 21 and prevent the clamping plate 21 from loosening under the jumping of the cable.

As shown in fig. 1, the frame 1 is provided with an adjusting slot 12, and the relative distance between the two pressure rollers 22 can be adjusted through the adjusting slot 12. Since the outer diameter of the test cable is different, the distance between the pressure rollers 22 can also be adjusted in order to allow the test cable to pass between the two pressure rollers 22 and be better clamped.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
