[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figure 1 and Figure 2 As shown, an impact head for component testing includes an impact rod 1 and an adjustment assembly 3. A limit plate 2 is installed on the upper end of the impact rod 1. The adjustment assembly 3, used for adjusting the impact contact surface, is located on the lower end of the impact rod 1. The adjustment assembly 3 includes a fixed threaded strip 301, an adjusting tube 1 302, an anti-slip strip 303, an adjusting threaded strip 304, an adjusting tube 2 305, an adjusting tube 306, an adjusting tube 4 307, and an adjusting tube 5 308. The adjusting tube 1 302 is installed on the outside of the fixed threaded strip 301. The adjusting tube 1 302 rotates on the fixed threaded strip 301 on the surface of the impact rod 1 to adjust its height. The adjusting tubes 1 302, 2 305, 3 306, 4 307, and 5 308 can all be adjusted in height to adjust the impact size at the lower end of the impact rod 1, allowing for appropriate impact adjustment according to the test requirements. On the surface of the first adjusting tube 302, an anti-slip strip 303 is installed at the upper end. The anti-slip strip 303 assists the first adjusting tube 302, the second adjusting tube 305, the third adjusting tube 306, the fourth adjusting tube 307, and the fifth adjusting tube 308 in preventing slippage during rotation adjustment. An adjusting threaded strip 304 is installed at the lower end of the surface of the first adjusting tube 302. An adjusting tube 2 305 is installed outside the adjusting threaded strip 304. An adjusting tube 306 is installed outside the second adjusting tube 305. An adjusting tube 4 307 is installed outside the third adjusting tube 306. An adjusting tube 5 308 is installed outside the fourth adjusting tube 307. The first adjusting tube 302 and the anti-slip strip 303 are fixedly connected. The first adjusting tube 302 and the second adjusting tube 305 are threadedly connected. The adjusting threaded strip 304 and the second adjusting tube 305 are threadedly connected. The adjusting threaded strip 304 and the first adjusting tube 302 are fixedly connected.
[0022] like Figure 3As shown, the upper end of the impact rod 1 is connected to an assembly rod 4. The assembly rod 4 allows the impact rod 1 to be inserted into the interface of the test fixture of the component. An extrusion strip 5 is mounted on the surface of the assembly rod 4, and a mounting cap 6 is mounted on the outside of the assembly rod 4. The freely rotatable mounting cap 6 is connected to the fixture thread by rotation when the assembly rod 4 is connected, making installation convenient and secure, and disassembly easy. The assembly rod 4 and the mounting cap 6 are movably connected. A reinforcing hook 7 is mounted on the upper end of the adjusting tube 302, and the reinforcing hook 7 is positioned relative to the adjusting tube 302. Two sets of protective components are symmetrically arranged along the center line. The lower end of the mounting cap 6 is equipped with a protective component 8 to prevent loosening. There are two sets of protective components 8. The protective component 8 includes a telescopic rod 801 and a connecting hook 802. The lower end of the telescopic rod 801 is equipped with a connecting hook 802. The telescopic rod 801 adjusts the position of the connecting hook 802 according to the position of the reinforcing hook 7 by telescopic extension and contraction under the fixing action of the bolt. After the connecting hook 802 and the reinforcing hook 7 are connected, they provide auxiliary limit for the adjusted tube to prevent loosening during the test.
[0023] In summary, the impact head of the test fixture for this component is first based on... Figures 1-3 The structure shown is such that, during installation, the assembly rod 4 at the top of the impact rod 1 is inserted into the interface of the test fixture of the component. Then, the mounting cap 6 is rotated to connect the assembly rod 4 via a screw thread to the fixture interface. The installation is convenient and secure. When conducting comparative tests to adjust the impact surface (such as optimizing component design), the impact energy, velocity, and other parameters are kept constant. Then, the height position of the adjusting tube 1 302 is adjusted by rotating it on the fixed threaded strip 301 on the surface of the impact rod 1. The external adjusting tubes 1 302, 2 305, 3 306, 4 307, and 5 308 can be adjusted separately. Adjust the height to adjust the impact dimension at the lower end of the impact rod 1, so that the test of the parts can be adjusted to a suitable impact surface according to the test requirements. During adjustment, hold the auxiliary adjustment tubes 302, 305, 306, 307 and 308 outside the anti-slip strip 303 to rotate and adjust to improve the anti-slip effect. After adjustment, pull the telescopic rod 801 to adjust the position of the connecting hook 802 according to the position of the reinforcing hook 7 under the fixing action of the bolt, so that the connecting hook 802 and the reinforcing hook 7 are connected. After connection, the adjusted adjustment tube is auxiliaryly limited to prevent it from loosening during the test.
