Description

Technical Field

[0001] This utility model relates to the technical field of strength testing equipment, specifically to a strength testing device for aluminum alloy wire. Background Technology

[0002] The characteristics of aluminum alloy wire include: acid and alkali resistance, corrosion resistance, good toughness, high strength, and no fading at high temperatures up to 120 degrees Celsius. For most aluminum alloy wires, strength testing typically requires the operator to bind both ends to predetermined tensile testing positions during installation and positioning. However, existing aluminum alloy wire strength testing equipment (announcement number: CN219455757U) has the following disadvantages in use:

[0003] In its use, the aluminum alloy wire is wound into the winding groove and then sealed and protected by the closed collar against the surface of the fixed support. However, since the size of the winding groove is fixed, the aluminum alloy wire is not fixed when it is wound in the winding groove, and it is easy to move in the winding groove, which affects the strength test. Therefore, this patent proposes an aluminum alloy wire strength testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy wire strength testing device to solve the problems mentioned in the background art.

[0006] Preferably, the inner wall of the movable sleeve is provided with a limiting groove, and the outer wall of the mounting sleeve is fixed with a limiting block, which slides within the limiting groove.

[0007] Preferably, the outer wall of the movable sleeve is provided with a sliding groove, and the inner wall of the limiting sleeve is fixed with a movable block, which is slidably connected in the sliding groove.

[0010] Preferably, the inner wall of the support frame is provided with a connecting groove, and a slider is fixed on one side of the mounting base, the slider being slidably connected in the connecting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By winding an aluminum alloy wire around the surface of the mounting sleeve and then rotating the rotating part in the forward direction, the moving sleeve moves forward and limits and clamps the wound aluminum alloy wire. Then, by moving the limiting sleeve, the aluminum alloy wire is clamped between the fixing part and the limiting sleeve. The limiting part is fixed by screwing it on, so that the limiting part is pressed against the outer wall of the moving sleeve. Then, the other end of the aluminum alloy wire is fixed between the moving part and the limiting sleeve in the same way. In this way, the wound part and the extended part of the aluminum alloy wire are fixed, preventing the wound part of the aluminum alloy wire from moving during the test and affecting the test results.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] The characteristics of aluminum alloy wire: acid and alkali resistance, corrosion resistance, good toughness, high strength, and no fading at high temperatures of 120 degrees Celsius. For most aluminum alloy wires, strength testing typically involves the operator binding both ends to predetermined tensile testing positions during installation and positioning. This invention provides an aluminum alloy wire strength testing device that winds the aluminum alloy wire around the surface of the mounting sleeve 4. Then, rotating the rotating part 6 forward moves the moving sleeve 5 forward, limiting and clamping the wound aluminum alloy wire. The moving limiting sleeve 13 then clamps the aluminum alloy wire between the fixing part 2 and the limiting sleeve 13. The limiting part 14 is screwed in, pressing against the outer wall of the moving sleeve 5 to fix the limiting sleeve 13. The other end of the aluminum alloy wire is then fixed between the moving part 3 and the limiting sleeve 13 using the same method. This fixes both the wound and extended portions of the aluminum alloy wire, preventing movement of the wound portion during testing and ensuring accurate results.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: an aluminum alloy wire strength testing device, including a support frame 1, a fixing member 2 fixed to the inner wall of the support frame 1, a movable member 3 slidably connected to the inner wall of the support frame 1, an installation sleeve 4 fixed to one side of both the fixing member 2 and the movable member 3, a threaded groove 8 opened in the installation sleeve 4, a screw rod 7 screwed into the installation sleeve 4, a rotating member 6 fixed to one side of the screw rod 7, a movable sleeve 5 rotatably connected to the side of the rotating member 6 near the installation sleeve 4, the movable sleeve 5 slidably connected to the outer wall of the installation sleeve 4, a limiting sleeve 13 slidably connected to the outer wall of the movable sleeve 5, and a limiting member 14 screwed onto the limiting sleeve 13.

[0021] It should be noted that by winding the aluminum alloy wire around the surface of the mounting sleeve 4 and then rotating the rotating part 6 in the forward direction, the moving sleeve 5 moves forward. The moving sleeve 5 clamps and limits the wound aluminum alloy wire. Then, by moving the limiting sleeve 13, the aluminum alloy wire is clamped between the fixing part 2 and the limiting sleeve 13. And by screwing the limiting part 14, the limiting part 14 is pressed against the outer wall of the moving sleeve 5 to fix the limiting sleeve 13. Then, the other end of the aluminum alloy wire is fixed between the moving part 3 and the limiting sleeve 13 in the same way. In this way, the wound part and the extended part of the aluminum alloy wire are fixed, preventing the wound part of the aluminum alloy wire from moving during the test and affecting the test results.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the movable sleeve 5 has a limiting groove 9, and the outer wall of the mounting sleeve 4 is fixed with a limiting block 10, which slides within the limiting groove 9. The outer wall of the movable sleeve 5 has a sliding groove 12, and the inner wall of the limiting sleeve 13 has a movable block 11, which is slidably connected within the sliding groove 12. The limiting sleeve 13, the movable component 3, and the fixing component 2 all have fixing grooves.

[0023] It should be noted that by setting the limiting block 10 and the limiting groove 9, the movable sleeve 5 can only slide horizontally on the outer wall of the mounting sleeve 4 to limit and clamp the wound aluminum alloy wire. By setting the movable block 11 and the sliding groove 12, the limiting sleeve 13 can only move horizontally and clamp the protruding part of the aluminum alloy wire through the fixing groove.

[0024] like Figure 1 As shown, an electric telescopic rod 16 is fixed to the inner wall of the top of the support frame 1. A mounting base 15 is fixed to the telescopic end of the electric telescopic rod 16. A force sensor 18 is installed at the bottom of the mounting base 15. A fixed base 19 is fixed to the top of the moving part 3. The fixed base 19 and the force sensor 18 are fixed together. A displacement sensor 20 is installed at one end of the mounting base 15. A connecting groove 17 is opened on the inner wall of the support frame 1. A slider is fixed to one side of the mounting base 15. The slider is slidably connected in the connecting groove 17.

[0025] It should be noted that the electric telescopic rod 16 drives the mounting base 15 to move, and the movement of the mounting base 15 moves the power sensor 18 and the moving part 3 to detect the strength of the aluminum alloy wire until the aluminum alloy wire breaks. During this process, the equipment records the maximum tensile force value and the displacement sensor 20 records the corresponding elongation of the aluminum alloy wire. The maximum tensile force value is the tensile strength of the aluminum alloy wire. During the detection process, the data detected by the force sensor 18 and the displacement sensor 20 are transmitted to the external control panel, which allows the operator to observe the changes in tensile force and displacement, and can automatically output the data of maximum tensile force and elongation when the wire breaks. In this solution, the control method of the electrical components is controlled by the matching external control panel, and the control circuit can be implemented by those skilled in the art through simple programming. It is common knowledge in the field and is only used without modification. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
