[0024] The following is the specific embodiment of the utility model and combines the drawings, and the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.
[0025] For example, Figures 1 to 4As shown in the figure, a pendulum impact device comprises a pendulum 1, a base 2 and an abutting piece 3. Its features are that the pendulum 1 is connected with a rotating shaft 6, and the pendulum 1 is provided with the base 2 on both sides and the base 2 is symmetrically arranged. The pendulum 1 is provided with a containing space 4 in which a tooling 1001 can be placed, and the containing space 4 is connected with an impact blade 5. The base 2 is connected with the abutting piece 3. The abutting piece 3 is L-shaped, a first through hole 31 is formed on one side of the abutting piece 3, and the abutting piece 3 is connected with the base 2 through screw connection. The abutting piece 3 is connected with a protrusion 32 on the side close to the pendulum 1, and the tooling 1001 can be placed between the two abutting pieces 3. By setting the height of the pendulum 1, the pendulum 1 is lifted to a certain height, so that it has a certain potential energy. When the pendulum 1 freely falls to impact the tooling 1001, the potential energy will become kinetic energy, so that the tooling 1001 is deformed or broken, and finally the energy change before and after the pendulum 1 can be calculated to calculate a value to judge the material performance of the tooling 1001.
[0026] In the utility model, the abutting piece 3 can make the tooling 1001 as far as possible in the original position when being impacted, thereby reducing the error caused by position deviation.
[0027] As shown in the figure, Figure 1 , Figure 2 and Figure 4 , the base 2 comprises a first fixing piece 21 and a second fixing piece 22. The first fixing piece 21 is slightly smaller than the second fixing piece 22, the upper surface of the first fixing piece 21 is provided with a second through hole 211, and the second fixing piece 22 is threadedly connected with the first fixing piece 21. The first fixing piece 21 and the second fixing piece 22 can be more firmly connected through thread connection, and replacement is also facilitated.
[0028] As shown in the figure, Figure 1 , Figure 2 , one end of the abutting piece 3 is attached to one side of the first fixing piece 21. In the utility model, after the tooling 1001 is impacted, due to the placement of the tooling 1001 on the base 2, the tooling 1001 will generate a force away from the base 2 due to the action of force. The effect of the force of the tooling 1001 can be transmitted to the abutting piece 3. By abutting the abutting piece 3 on one side of the fixing piece 21, when the abutting piece 3 is subjected to the force applied by the tooling 1001, the effect of the force can also be transmitted to the fixing piece 21 due to the mutual action of the force. Finally, the effect of balancing the force can be achieved.
[0029] As shown in the figure, Figure 2As shown, one end of the rotating shaft 6 is connected to a motor 7. The power source for the rotating shaft 6 is the motor 7. By setting the rotational speed of the motor 7, we can calculate the magnitude of the force applied by the pendulum 1 to the tooling 1001 using mechanical formulas. Then, by detecting the size of the notch after testing the tooling 1001, we can determine the toughness and impact resistance of the material of the test tooling 1001.
[0030] In this utility model, the motor 7 is existing technology.
[0031] like Figure 4 As shown, the second fixing member 22 has several threaded holes 221. The spacing between the threaded holes 221 should be the same as the spacing between the holes on the abutment member 3. In this utility model, providing multiple holes on the second fixing member 22 can adjust the position of the abutment member 3 on the base 2. The change in the position of the abutment member 3 can be adapted to various tooling lengths 1001, making it easier to operate and more adaptable.
[0032] like Figure 2 As shown, the bend at the connection surface between the abutment 3 and the second fixing member 22 is circular. In this utility model, the second fixing member 22 is a cuboid with right-angled sides. The circular bend at the connection between the abutment 3 and the second fixing member 22 is more practical.
[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0034] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
