Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping devices, and particularly relates to a clamping device for detecting the resistivity of nickel strips. Background Technique
[0002] Due to its good electrical conductivity and corrosion resistance, nickel strips are widely used in electronic products, battery manufacturing, resistance elements, and electromagnetic devices. Measuring the resistivity of nickel strips is crucial for ensuring that they meet the performance requirements of specific applications, such as controlling resistance values, optimizing thermal performance, and evaluating material quality. The existing detection of nickel strip resistivity usually uses the four-probe method. The four-probe method is particularly suitable for measuring the resistivity of thin-layer or small-volume samples because it can minimize errors caused by edge effects and surface irregularities, which is particularly important for measuring the resistivity of thin nickel strips.
[0003] When the existing nickel strip resistivity detection is used, there are certain drawbacks. First, due to the thin thickness of the nickel strip, the force on the nickel strip is uneven during the clamping process, resulting in inaccurate measurement data caused by damage to the nickel strip by the fixture. The clamping width cannot be adjusted, and nickel strips of different sizes cannot be clamped. Only a single position on the nickel strip is detected, which cannot guarantee the accuracy of the measurement results. The working environment of the nickel strip in daily use cannot be simulated, resulting in inconsistent actual use and measurement results.
[0004] Therefore, a clamping device for detecting the resistivity of nickel strips is proposed. Content of the Utility Model
[0005] The main purpose of the utility model is to provide a clamping device for detecting the resistivity of nickel strips, which can effectively solve the problems that the force on the nickel strip is uneven during the clamping process, resulting in damage, inaccurate measurement data caused by damage to the nickel strip by the fixture, inability to adjust the clamping width, inability to clamp nickel strips of different sizes, only detecting a single position on the nickel strip, inability to guarantee the accuracy of the measurement results, inability to simulate the working environment of the nickel strip in daily use, and resulting in inconsistent actual use and measurement results.
[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows: A clamping device for detecting the resistivity of nickel strips, comprising a bottom plate, on which four first sliding grooves are opened. The left and right sides of the four first sliding grooves are respectively a group. In both groups of the first sliding grooves, clamping mechanisms are slidably installed. The two clamping mechanisms have exactly the same structure. Each of the two clamping mechanisms includes two first sliders, and the two first sliders are slidably arranged in the corresponding first sliding grooves. At the upper ends of the two first sliders, a support frame is fixedly installed. At the upper end of the support frame, a first installation groove is opened. In the first installation groove, three springs are fixedly installed at equal intervals. A square tube is sleeved in the first installation groove. At the upper end of the square tube, a first rubber plate is fixedly installed. At both sides of the upper end of the support frame, insertion slots are opened. In the insertion slots, insertion rods are movably inserted. At the upper ends of the insertion rods, second rubber plates are fixedly installed. At the lower ends of the insertion rods, racks are fixedly installed. In the inner parts of both sides of the support frame, second installation grooves are opened. On one side of the support frame, a first motor is fixedly installed. The output shaft of the first motor penetrates through the support frame and is fixedly installed with a rotating shaft. At both ends of the rotating shaft, gears are fixedly sleeved, and the two gears are located in the second installation grooves. The two gears are meshed with the racks.
[0007] Preferably, an outer shell is fixedly installed at the upper end of the bottom plate. On both sides inside the outer shell, two first hydraulic cylinders are fixedly installed. At one end of each of the four first hydraulic cylinders, a first telescopic rod is provided. At one end of each of the four first telescopic rods, it is fixedly connected to the corresponding support frame.
[0008] Preferably, a second sliding groove is opened at the upper end of the bottom plate. On one side of the bottom plate, a second motor is fixedly installed. The output shaft of the second motor is fixedly installed with a screw rod, and the other end of the screw rod is rotatably connected to one end of the second sliding groove. In the second sliding groove, a second slider is slidably arranged, and the second slider is threadedly connected to the screw rod. At the upper end of the second slider, a second hydraulic cylinder is fixedly installed. At one end of the second hydraulic cylinder, a second telescopic rod is provided. At the upper end of the second telescopic rod, a fixing piece is fixedly installed. At the upper end of the fixing piece, a detection needle is provided.
[0009] Preferably, an electric heating coil is fixedly installed at the center of the upper end of the outer shell. An air duct is fixedly installed at the upper end of the outer shell, and the air duct is communicated with the inside of the outer shell. Inside the upper end of the air duct, a fixing frame is fixedly installed. At the upper end of the fixing frame, a third motor is fixedly installed. The output shaft of the third motor penetrates through the fixing frame and is installed with a fan blade.
[0010] Preferably, a detection port is opened on one side of the outer shell.

[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1. The clamping mechanism provided by the utility model reduces the damage of the nickel strip caused by uneven force during the clamping process, and realizes the adjustment of the clamping width. By controlling the first motor installed on the support frame to rotate the rotating shaft, the two gears fixedly installed on the corresponding rotating shafts can rotate in the second installation groove, so that the meshing racks move up and down in the differential connection groove, and the insertion rods at the upper ends of the racks drive the second rubber plate to move up and down. Controlling the first motor to move the second rubber plate downward can press the nickel strip placed on the first rubber plate downward, so that the spring contracts until the square cylinder is completely located in the first installation groove. Therefore, the nickel strip is more evenly stressed during the clamping process, reducing the inaccurate measurement data caused by the damage of the nickel strip due to uneven force during the clamping process. By pushing the clamping mechanism, the first slider provided on the clamping mechanism slides in the corresponding first chute to adjust the width between the two clamping mechanisms, realizing the adjustment of the clamping width. Therefore, the clamping resistance detection of nickel strips of different sizes can be carried out.
[0014] 2. The second slider provided by the utility model improves the accuracy of the measurement result. By controlling the second motor to rotate the screw rod, the second slider threadedly connected to the screw rod will move back and forth in the second chute. Controlling the second hydraulic cylinder to extend the second telescopic rod can drive the fixed piece and the detection needle installed at the upper end of the second telescopic rod to move up and down. Controlling the second slider to move to different positions in the second chute to extend the detection needle can detect different positions on the nickel strip. Measuring at multiple positions and taking the average value can reduce random errors and improve the accuracy of the measurement result.
[0015] 3. The electric heating coil provided by the utility model realizes the detection of the resistivity of the nickel strip during use. By controlling the electric heating coil to start heating and controlling the third motor installed on the fixed frame to rotate the fan blade, the temperature generated by the electric heating coil evenly heats the nickel strip. Therefore, the working environment of the nickel strip during daily use can be simulated, the resistivity of the nickel strip during use can be detected, and the failure rate of the nickel strip during use can be reduced.
