Description

Technical Field

[0001] This utility model relates to the field of ultrafine copper wire tensile testing technology, specifically a fixture for ultrafine copper wire tensile testing. Background Technology

[0002] Ultrafine copper wire is a copper conductor with an extremely small diameter, typically used in electronic applications requiring high precision and performance. Tensile testing aims to evaluate the mechanical properties of ultrafine copper wire and verify the reliability of the material. Fixtures are used to maintain structural stability during ultrafine copper wire testing. Existing fixtures for ultrafine copper wire tensile testing utilize clamping force to constrain the structure of the ultrafine copper wire. However, due to the small size of the ultrafine copper wire, the area of ​​application of the clamping force is limited, making it prone to detachment during testing, thus affecting testing efficiency and limiting applicability. Therefore, a fixture that overcomes these shortcomings is needed to improve performance. Utility Model Content

[0003] The purpose of this utility model is to provide a fixture for tensile testing of ultrafine copper wire, in order to solve the problem mentioned in the background art that the existing fixtures for tensile testing of ultrafine copper wire utilize clamping force to limit the structure of the ultrafine copper wire. However, because the ultrafine copper wire itself is small, the area of ​​the clamping force is limited, and it is easy to fall off during the test, thus affecting the efficiency of the test and having insufficient applicability.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a fixture for tensile testing of ultra-fine copper wire, comprising:

[0006] A clamping structure, the clamping structure including a movable clamping block, the lower end of which is fitted with a fixed clamping block;

[0007] An auxiliary clamping structure includes a guide frame, which is fixed at equal intervals on the upper part of the back of the fixed clamping block. A limiting ball is placed inside the upper end of the guide frame. A columnar protrusion is provided on one side of the outer surface of the limiting ball, and a through hole is provided at one end of the columnar protrusion.

[0008] Furthermore, the clamp structure also includes a through-hole, which is equidistantly opened at the center of the inner side of the movable clamping block and the fixed clamping block, and the columnar protrusion extends into the through-hole, with the outer surface of the limiting ball abutting against the outer edge of the through-hole.

[0009] Furthermore, positioning blocks are welded to the lower parts of both sides of the fixing block, and positioning holes are opened through the middle of the positioning blocks.

[0010] Furthermore, it also includes a docking structure, which includes docking posts and threaded tubes. A set of docking posts are symmetrically arranged vertically. A docking tube is threaded at the docking point of a set of docking posts. A threaded post is fixed in the middle of one end of each docking post. A positioning ring is fixed in the lower part of the outer surface of the threaded tube. The positioning ring extends into the movable clamping block through bolts that pass through the middle at equal intervals. One of the threaded posts extends into the threaded tube.

[0011] Furthermore, it also includes an auxiliary cleaning structure, which includes a cleaning frame and a hole block. The cleaning frame is fitted onto the lower part of the front side of the fixed clamping block, and the hole block is equidistantly inserted into the lower part of the back side of the fixed clamping block. A connecting pipe is fitted into the middle of one end of the hole block.

[0012] Furthermore, openings are provided at the ends of both sides of the cleaning frame, and sleeves are fitted inside the openings. A partition plate is fitted at one end of the sleeve, and the inner side of the partition plate is in contact with the cleaning frame.

[0013] This utility model has the following beneficial effects:

[0014] This invention utilizes the connection between the limiting ball and the ultra-fine copper wire, and further relies on the contact between the limiting ball and the outer edge of the opening. When the movable clamping block and the fixed clamping block are in the clamping state, the limiting ball can further ensure the stability of the ultra-fine copper wire structure during the test, which helps to improve the test results, facilitates use, and meets the requirements.

[0015] Based on the aforementioned beneficial effects, in the experiment on ultra-fine copper wire, the cleaning rack is set below the ultra-fine copper wire in the experiment. If the ultra-fine copper wire breaks during the experiment, the cleaning rack can be used to catch the broken ultra-fine copper wire. Then, through the connection between the pipe and the external suction fan, the ultra-fine copper wire caught on the cleaning rack after the breakage can be adsorbed for centralized cleaning, reducing the intensity and difficulty of subsequent cleaning, and saving time and effort.

[0023] 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.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is a fixture for tensile testing of ultra-fine copper wire, comprising:

[0026] The clamping structure includes a movable clamping block 11, and a fixed clamping block 12 is attached to the lower end of the movable clamping block 11.

[0027] The movable clamping block 11 and the fixed clamping block 12 form an integral clamping structure, which can clamp and position the ultra-fine copper wire to be tested.

[0028] The auxiliary clamping structure includes a guide frame 21, which is fixed at equal intervals on the upper part of the back of the fixed clamping block 12. A limiting ball 22 is placed inside the upper end of the guide frame 21. A columnar protrusion 23 is provided on one side of the outer surface of the limiting ball 22, and a through hole is provided at one end of the columnar protrusion 23.

[0029] The guide frame 21 provides structural support for the limiting ball 22. With the help of the limiting ball 22 and the columnar protrusion 23, the ultra-fine copper wire to be tested is bolted and limited, which can further ensure the stability of the ultra-fine copper wire structure during the test.

[0030] The clamp structure also includes a through-hole 13, which is equidistantly opened in the center of the inner side of the movable clamping block 11 and the fixed clamping block 12, and the columnar protrusion 23 extends into the through-hole 13, and the outer surface of the limiting ball 22 abuts against the outer edge of the through-hole 13.

[0031] The opening 13 allows the ultra-fine copper wire to freely pass through the movable clamp 11 and the fixed clamp 12 during the test.

[0032] Positioning blocks 14 are welded to the lower parts of both sides of the fixing block 12, and positioning holes are opened through the middle of the positioning blocks 14.

[0033] By inserting and tightening bolts into the positioning holes, the positioning block 14 can be fixed, thereby limiting the fixing clamp block 12.

[0034] It also includes a docking structure, which includes docking posts 41 and threaded tubes. A set of docking posts 41 are symmetrically arranged vertically. A docking tube 42 is threaded at the docking point of a set of docking posts 41. A threaded post 43 is fixed in the middle of one end of the docking post 41. A positioning ring 45 is fixed in the lower part of the outer surface of the threaded tube. The positioning ring 45 extends into the movable clamping block 11 through bolts that pass through the middle at equal intervals. A threaded post 43 extends into the threaded tube.

[0035] The connecting pipe 42 connects a set of connecting columns 41 by thread. The length of the connecting columns 41 can be adjusted by the extension and retraction of the thread. The positioning ring 45 is used with bolts to install and fix the threaded pipe. The connecting column 41 can be installed and fixed by the threaded pipe supporting the threaded column 43. The connection between the threaded column 43 and the external hydraulic cylinder can meet the lifting and lowering requirements of the clamp.

[0036] Working principle: By extending and retracting the connecting pipe 42, a set of connecting columns 41 can be adjusted to a reasonable length. Then, a set of threaded columns 43 can be used to connect with the hydraulic cylinder and the threaded pipe respectively. The movable clamping block 11 can be connected to the external hydraulic cylinder. Then, the bolts are inserted into the positioning hole and tightened to fix the positioning block 14, thereby limiting the fixed clamping block 12. At this time, the ultra-fine copper wire to be tested is passed through the through 13 and bolted to the columnar protrusion 23. Then, the controlled external hydraulic cylinder applies a downward force to the movable clamping block 11, so that the movable clamping block 11 and the fixed clamping block 12 fit and abut against each other.

[0037] This solution ensures the stability of the ultra-fine copper wire structure during the test clamping process, prevents detachment, helps improve test results, is easy to use, and meets the requirements.

[0038] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0039] It also includes an auxiliary cleaning structure, which includes a cleaning frame 31 and a hole block 32. The cleaning frame 31 is fitted on the lower part of the front side of the fixed clamping block 12, and the hole block 32 is equidistantly inserted through the lower part of the back side of the fixed clamping block 12. A connecting pipe 33 is fitted inside the middle of one end of the hole block 32.

[0040] The cleaning rack 31 collects broken ultra-fine copper wires from the test. It is connected to the connecting pipe 42 via the hole block 32, and then connected to the external suction fan via the connecting pipe 33. This allows for the concentrated adsorption and collection of the broken ultra-fine copper wires on the cleaning rack 31, reducing the intensity of subsequent manual cleaning and saving time and effort.

[0041] The cleaning frame 31 has openings at both ends, and a sleeve post 34 is fitted inside the opening. A partition plate 35 is fitted at one end of the sleeve post 34, and the inner side of the partition plate 35 is in contact with the cleaning frame 31.

[0042] The open sleeve column 34 is used for installation. The sleeve column 34 can be used to assemble the cleaning frame 31 with the fixed clamping block 12 and multiple cleaning frames 31, and can also be used to install the isolation plate 35. The isolation plate 35 can prevent the ultra-fine copper wires being detached from the cleaning frame 31.

[0043] Working principle: In the above tensile test of ultrafine copper wire, multiple cleaning racks 31 are assembled according to the test requirements. That is, multiple cleaning racks 31 are assembled and installed by means of the sleeve 34 and the opening. After assembly and installation, the isolation plate 35 can be sleeved on the last cleaning rack 31. The cleaning rack 31 is used to receive the ultrafine copper wire that breaks during the tensile test. Then, the connecting pipe 33 is connected to the external suction fan, which can centrally adsorb and collect the broken ultrafine copper wire received on the cleaning rack 31, and then centrally clean it.

[0044] This solution can reduce the intensity and difficulty of subsequent cleanup, saving time and effort.
