The terms used in the description of this utility model are only for the purpose of describing specific embodiments and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.
[0031] As Figures 1 to 6 shown, the carbon fiber sample conductivity testing tooling includes: a clamping mechanism 1, a sliding mechanism 2 and a driving mechanism 3.
[0032] As Figure 1 、 Figure 2 shown, the clamping mechanism 1 includes a first clamping member 11 and a second clamping member 12 arranged in parallel for clamping the carbon fiber sample 01.
[0033] The sliding mechanism 2 is connected to the first clamping member 11 and / or the second clamping member 12 and is used to guide the first clamping member 11 and the second clamping member 12 to move linearly when approaching each other. Continuing to refer to Figure 1 、 Figure 2 , the sliding mechanism 2 can be only connected to the first clamping member 11 to make the first clamping member 11 move towards the second clamping member 12; it can also be only connected to the second clamping member 12 to make the second clamping member 12 move towards the first clamping member 11, or it can be connected to both the first clamping member 11 and the second clamping member 12 at the same time to make the first clamping member 11 and the second clamping member 12 approach and move away from each other. There are many structural forms of the sliding mechanism 2, which can be a linear guide rail, a sliding bearing, or other mechanical structures that can ensure linear motion.
[0034] The driving mechanism 3 is used to drive the first clamping member 11 and / or the second clamping member 12 to approach or move away from each other in the opposite direction. According to the connection method of the above-mentioned sliding mechanism 2, the form of the driving mechanism 3 is set. It should be noted here that there are many structural forms of the driving mechanism 3, which can be a manually adjustable screw, an electric push rod, or other mechanical devices that can precisely control the movement of the clamping member.
[0035] Among them, a positive electrode 13 is fixed on the end surface of the first clamping member 11 facing the second clamping member 12, and a negative electrode 14 is fixed on the end surface of the second clamping member 12 facing the first clamping member 11. The positive electrode 13 is connected to the positive power supply electrode of the conductivity tester, and the negative electrode 14 is connected to the negative power supply electrode of the conductivity tester. Continuing as Figure 1 , Figure 2 shown, there are many forms of the electrodes, which can be needle-shaped electrodes, sheet-shaped electrodes, or other conductive electrode forms such as elastic electrodes.
[0036] As Figure 1 shown, the driving mechanism 3 drives the sliding mechanism 2 to open, places the carbon fiber sample 01 to be tested between the first clamping member 11 and the second clamping member 12, drives the sliding mechanism 2 to close, clamps the carbon fiber sample 01, makes the positive electrode 13 fit with one end of the carbon fiber sample 01, makes the negative electrode 14 fit with the other end of the carbon fiber sample 01, and finally energizes the positive electrode 13 and the negative electrode 14, and measures the conductivity passing through the carbon fiber sample 01 by the conductivity tester.
[0037] The utility model fixes the carbon fiber sample 01 through the clamping mechanism 1 to prevent the sample from sliding or loosening during the test, guides and clamps the direction of the carbon fiber sample 01 through the sliding mechanism 2 to keep the alignment between both ends of the carbon fiber sample 01 and the positive and negative electrodes 14, then realizes the relative movement between the first clamping member 11 and the second clamping member 12 through the driving mechanism 3, and finally tests the conductivity of the carbon fiber sample 01 through the positive and negative electrodes in contact with the carbon fiber sample 01 and the conductivity tester connected to the positive and negative electrodes, so as to adapt to carbon fiber samples of different shapes and sizes, provide stable and reliable electrical contact, simplify the test process, thereby reducing the operation difficulty, and ensuring the accuracy of the test results at the same time.
[0038] In some embodiments of the utility model, the sliding mechanism 2 includes a first fixed block 21 arranged in parallel with the first clamping member 11, two connecting rods 22 for connecting between the first clamping member 11 and the first fixed block 21, and the second clamping member 12 is slidably arranged relative to the two connecting rods 22. Continuing to refer to Figure 1 , Figure 2As shown, the second clamping member 12 can be arranged between the two connecting rods 22, sleeved on the two connecting rods 22, or in other forms that can both clamp the carbon fiber sample 01 and slide relatively between the two connecting rods 22. The connection of the two connecting rods 22 to the first fixing block 21 provides a more stable sliding track for the test, ensuring the stability and reliability of the second clamping member 12 during the sliding process, and at the same time increasing the clamping force of the first clamping member 11 and the second clamping member 12 on the carbon fiber sample 01. Using the two connecting rods 22 to move the first clamping member 11 and the second clamping member 12 closer or farther apart can more precisely control the distance between the first clamping member 11 and the second clamping member 12.
[0039] As Figure 2 , Figure 3 shown, two first through holes 15 are formed in the second clamping member 12, and the two connecting rods 22 respectively pass through the two first through holes 15. The two through holes play a guiding role for the connecting rods 22, making the sliding of the second clamping member 12 on the connecting rods 22 more stable. At the same time, it can also improve the clamping stability of the first clamping member 11 and the second clamping member 12 on the carbon fiber sample 01, and is more convenient and fast during the assembly and adjustment process.
[0040] In some embodiments of the present utility model, a guiding shaft 16 is further fixedly connected to the inner side of the through hole, and the connecting rod 22 is in sliding contact with the inside of the guiding shaft 16. As Figure 2 , Figure 3 , Figure 5 shown, the guiding shaft 16 can provide a precise sliding path, enabling the connecting rod 22 to perform precise linear sliding inside the guiding shaft 16, and at the same time playing a supporting role for the connecting rod 22, making the sliding of the first fixing block 21 on the connecting rod 22 more stable.
[0041] In some embodiments of the present utility model, an anti-slip sleeve 17 is further provided between the guiding shaft 16 and the connecting rod 22. After the first clamping member 11 and the second clamping member 12 fix the carbon fiber sample 01, in order to make the clamping stable, a frictional force is generated between the two through the anti-slip sleeve 17, so that the connecting rod 22 is fixed in the guiding block. At the same time, the vibration during the sliding process can also be reduced through the setting of the anti-slip sleeve 17.
[0042] In some embodiments of the present utility model, the driving mechanism 3 is a driving rod 31. One end of the driving rod 31 is fixedly connected to the first clamping member 11, and a second through hole 21a is further formed in the first fixing block 21. The other end of the driving rod 31 passes through the second through hole 21a and extends to the outside of the first fixing block 21. As Figure 2 , Figure 4As shown, the second through-hole 21a provides a stable guiding function for the driving rod 31. The driving rod 31 drives the first clamping member 11 and the second clamping member 12 through a simple linear motion, and the operation is simple and convenient. It should also be noted here that there are many driving forms for the driving rod 31, which can be electric drive, manual adjustment, or other drivable forms.
[0043] To make the driving between the driving rod 31 and the second through-hole 21a more stable, an anti-slip gasket 23 is provided between the second through-hole 21a and the driving rod 31. As Figure 4 shown, the anti-slip gasket 23 increases the friction between the driving rod 31 and the second through-hole 21a, prevents the driving rod 31 from slipping during the adjustment process, ensures that the driving rod 31 can accurately transmit force during operation, avoids misoperation, improves the accuracy of position adjustment. At the same time, the anti-slip gasket 23 has wear-resistant performance, can reduce the wear between the driving rod 31 and the second through-hole 21a, extends the service life of the driving rod 31, and improves the durability of the tooling.
[0044] In some embodiments of the present invention, a locking member is also provided between the driving rod 31 and the second through-hole 21a. The locking member can fix the position of the driving rod 31, prevent the driving rod 31 from accidentally sliding during the adjustment process or after the adjustment stops, ensure that the clamping mechanism 1 remains stable at the set position. The driving rod 31 with a locking function can be quickly adjusted to the required position and immediately locked, simplifying the adjustment and locking process. It should be noted here that there are many forms of the locking member, which can be a manual locking nut, a spring lock pin, a quick-lock clamp, a twist-lock mechanism, or other locking members that can perform locking.
[0045] To make the placement of the carbon fiber sample 01 between the first clamping member 11 and the second clamping member 12 more secure, placement plates 18 are also provided on the first clamping member 11 and the second clamping member 12, and the placement plates 18 are arranged oppositely. As Figure 6 shown, the design of adding the placement plates 18 on the first clamping member 11 and the second clamping member 12 provides a stable support platform for the carbon fiber sample 01, protects the surface of the sample, improves the electrical contact effect, and simplifies the operation process. The placement plates 18 not only enhance the stability and protection effect of the sample, but also improve the accuracy and reliability of the conductivity test, and at the same time adapt to samples of different sizes and shapes, enhancing the applicability and operation convenience of the test tooling.
[0046] To prevent the carbon fiber sample 01 from shifting when fixed between the first clamping member 11 and the second clamping member 12, limiting grooves 19 are also provided on the first clamping member 11 and the second clamping member 12. As Figure 6As shown, the limiting groove 19 can effectively fix the position of the carbon fiber sample 01, enhance the positioning accuracy, prevent the sample from sliding. At the same time, the limiting groove 19 also improves the test accuracy and the stability of the sample, optimizes the electrode contact effect, and meets the test requirements of different carbon fiber samples 01, thus improving the overall performance of the testing tool for the conductivity of the carbon fiber sample 01.
