[0002] In the metal smelting production process, in addition to testing the hardness, melting temperature, tensile strength, etc. of the metal, the conductive properties of the metal also need to be tested. In the existing metal conductive properties testing process, manual operation with clamps or knob-type clamping structures are mostly used to connect the power line to the metal strip to be tested, and then the power is turned on and the conductive properties of the metal parts under different voltages are recorded.

[0020] The present application is further described in detail below with reference to the accompanying drawings.

[0021] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the working principle of the existing metal clamps for conductive experiments is first introduced.

[0022] In existing conductivity experiments, metal sheets are cut into strips, and then wires are connected at both ends to observe the conductivity under different voltages, as well as values such as heat generation. In the existing detection process, metal clamps need to be connected to both ends of the metal strip. However, in order to ensure the stability of the clamping, the existing clamps often have a large bite force, which makes manual operation more laborious. Alternatively, a spiral adjustment structure is set to adjust the clamping force, but it is easy to cause loose clamping, which creates a safety hazard. In addition, the manual operation speed is limited, resulting in low detection efficiency and a lot of time wasted on clamping and picking up the workpiece. Therefore, it is necessary to improve the existing clamps to solve these problems.

The connecting base plate 1 has a rectangular appearance, the fixed seat 2 is fixedly connected to the upper surface of the right end of the connecting base plate 1, the guide rail 3 is fixedly connected to the upper surface of the connecting base plate 1 corresponding to the middle position on the left side of the fixed seat 2, the sliding seat 11 is slidably connected to the guide rail 3, the connecting rod 4 is respectively fixedly connected to the respective two side surfaces of the fixed seat 2 and the sliding seat 11, the connecting block 5 is respectively fixedly connected to the respective surfaces of the fixed seat 2 and the sliding seat 11 corresponding to the inner side of the connecting rod 4, the middle of the pressure rod 6 is rotatably connected to the connecting shaft 7, and the ends of the connecting shaft 7 are respectively connected to the connecting rod 4 is rotatably connected, the connecting ends of the electric push rod 8 are respectively movably connected to the connecting blocks 5, the telescopic ends of the electric push rod 8 are movably connected to the outward ends of the pressure rod 6, the coil springs 9 are respectively fixedly connected to the lower surfaces of the pressure rods 6 close to each other, the pressing plates 10 are fixedly connected to the lower ends of the coil springs 9, the pressing plates 10 are respectively matched with the upper surfaces of the fixed seat 2 and the sliding seat 11 close to each other, the support blocks 12 are respectively fixedly connected to the upper surfaces of the two ends of the front side of the connecting base plate 1, the two ends of the lead screw 13 are respectively rotatably connected to the support blocks 12, the driving block 14 is fixedly connected to the surface of the front side of the sliding seat 11, the lead screw 13 is threadedly connected to the driving block 14, the servo motor 15 is fixedly connected to the surface of the right end of the front side of the connecting base plate 1, the end of the output shaft of the servo motor 15 is fixedly connected to one end of the lead screw 13, and the lower surface of the pressing plate 10 is matched with the two ends of the workpiece body 23.

[0024] Specifically, the connecting base plate 1 is used to provide a support and connection plane, so that the components can be installed in a centralized manner. The connecting base plate 1 is made of insulating material to avoid the occurrence of leakage at the bottom. The fixed seat 2 is fixedly connected, which is convenient for use as a reference connection position to achieve rapid connection of the workpiece body 23. The guide rail 3 can enable the sliding seat 11 to slide on it. When in use, the electric push rod 8 connected to the connecting block 5 is extended or shortened, thereby pushing one end of the pressure rod 6. The outward ends of the pressure rod 6 are respectively bent downward to facilitate shortening the moving distance during the adjustment process. The middle part of the pressure rod 6 is connected to the connecting rod 4 through the connecting shaft 7, which can make the adjacent ends of the two press downward or lift upward, thereby pressing the coil spring 9 downward, and the pressure at the lower end of the coil spring 9. The sheet 10 presses the two ends of the workpiece body 23 toward the fixed seat 2 and the sliding seat 11 respectively. Both are made of metal, preferably made of brass and other materials. The provided coil spring 9 can gradually increase the contact pressure between the pressing sheet 10 and the workpiece, which is convenient for flexible adjustment of the placement position and helps to reduce the pressure on the conductive workpiece body 23. The provided support block 12 can connect the screw 13. When the position needs to be adjusted, the servo motor 15 drives the screw 13 to rotate a certain angle, and then the driving block 14 drives the sliding seat 11 to move the position. The distance between the sliding seat 11 and the fixed seat 2 can be quickly adjusted to achieve rapid matching of workpiece bodies 23 of different lengths. Compared with the manual adjustment of distance and clamping steps, the speed is greatly improved, and the clamping reliability is good, the force is uniform, and it is not easy to loosen, and it is more practical.

[0033] See also Figure 1 As another specific embodiment provided by the application, it also includes a pad 20, which is fixedly connected to the lower surface of the connecting base plate 1.

[0034] Specifically, the setting of the pad 20 can increase the friction resistance when placed on the supporting plane, while further improving the insulation performance to ensure safe insulation between the upper end and the operating plane.
