Description

Technical Field

[0001] The utility model relates to the technical field of bending test equipment, in particular to a multi-angle bending test machine. Background Art

[0002] The power cord is an electric wire that transmits electric current. Usually, the current is transmitted point to point. After the power cord is produced, a bending tester is needed to test the tensile and torsional properties of the power cord.

[0003] For example, the utility model: "Power Cord Bending Tester", with the announcement number: "CN211179349U", solves the problem that the existing bending tester is inconvenient for users to use by setting a base, a shell, a rotating mechanism, a tensile mechanism, a first fixed plate, a first self-locking chuck and a second self-locking chuck to cooperate with each other. The power cord can be tested at multiple angles without manual adjustment, which does not affect its test efficiency. However, during the implementation of this patent, only the first self-locking chuck and the second self-locking chuck can be used to fix the two ends of the wire respectively, and the wire cannot be fixed at any position. During the bending test, only the wire can be tested as a whole, and the local length of the wire cannot be tested. The device has poor adjustability and applicability. Therefore, the research and development of new multi-angle bending testers has received more and more attention from researchers. Utility Model Content

[0028] Furthermore, a maintenance compartment cover is provided on one side of the installation compartment 1 to facilitate maintenance of the interior of the installation compartment 1 .

[0029] Working principle:

[0030] When in use, the device is connected to a power source, and then one end of the wire is placed under the second clamping plate 17, and the other end of the wire is passed through the lead hole 5;

[0031] The staff can rotate the second bolt 22 clockwise, and the second bolt 22 drives the connecting rod 20 to rotate, and the connecting rod 20 rotates inside the second bearing 19, so that the connecting rod 20 does not drive the sliding plate 18 to rotate through the second bearing 19;

[0032] The second bolt 22 moves downward through the thread, and the second bolt 22 drives the connecting rod 20 to move together, so that the connecting rod 20 drives the sliding plate 18 to move through the second bearing 19, and the sliding plate 18 drives the second clamping plate 17 to move downward, so that the second clamping plate 17 is closely fitted with the wire, and the wire can be firmly clamped;

[0033] Then the staff can rotate the threaded rod 2, and the threaded tube 13 outside the threaded rod 2 is limited by the guide slider 14, so that the threaded tube 13 cannot rotate with the threaded rod 2, so that the threaded tube 13 can only move outside the threaded rod 2 through the thread;

[0034] At this time, the threaded tube 13 drives the guide slider 14 to slide along a straight line on the first sliding assembly 12, and the threaded tube 13 drives the fixing plate 4 to move together, so that the spacing between the fixing plate 4 and the U-shaped plate 9 can be adjusted, and the first clamping plate 6 can be moved to different positions of the wire;

[0035] After the adjustment is completed, the staff can rotate the first bolt 8 clockwise so that the first bolt 8 moves downward through the thread, and the first bolt 8 drives the first clamping plate 6 to move together, so that the first clamping plate 6 fits tightly with the wire, and the wire can be clamped firmly;

[0036] When conducting a multi-angle bending test, the staff can start the servo motor 11 through the control panel 15, so that the servo motor 11 drives the U-shaped plate 9 to rotate through the rotating shaft 10, thereby driving the wire to twist, and testing the torsion resistance and other properties of the wire. The wire can be tested at multiple angles.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
