Description

Technical Field

[0001] This utility model relates to an impact fatigue drop hammer test device for alloy parts, specifically an impact fatigue drop hammer test device for alloy parts, belonging to the technical field of impact fatigue drop hammer test for alloy parts. Background Technology

[0002] Alloy component impact fatigue drop hammer test equipment is a testing device used to evaluate the fatigue performance and durability of materials or components under repeated impact loads. This type of equipment is widely used in materials science, engineering, and product development, especially in industries such as aerospace, automotive manufacturing, and construction, where it is crucial for ensuring the safety and reliability of materials and components.

[0003] In the drop hammer impact fatigue test of alloy parts, most existing equipment uses a lead screw or hydraulic rod to lift the impact hammer, and then drops it for the impact test. However, the existing lead screw and hydraulic rod need to move to the position where the impact hammer has fallen after lifting it before they can lift the impact hammer again. Since the drop hammer test needs to be performed multiple times, this method of lifting the impact hammer takes a long time, which makes the test time longer. Utility Model Content

[0007] A fixing component is provided above the main frame. The fixing component includes a clamp that is fixedly connected to the upper surface of the main frame, and a sample is installed on the inner wall of the clamp.

[0008] Specifically, the drive assembly also includes a drive motor fixedly connected to the upper surface of the main frame. The output shaft of the drive motor is fixedly connected to the rotating shaft, and the drive motor provides power for the rotation of the rotating shaft.

[0009] Preferably, two linear slide rods are fixedly connected to the bottom surface of the upper hammer body, and the bottom ends of the two linear slide rods are fixedly connected to the upper surface of the lower hammer body. The linear slide rods serve to connect and reinforce the lower hammer body and the upper hammer body.

[0010] Furthermore, the inner wall of the U-shaped frame is fixedly connected to two symmetrical guide seats, and the two linear slide rods are slidably connected to the inner walls of the two guide seats respectively. The linear slide rods and guide seats play a guiding role in the movement of the lower hammer and punch.

[0012] 1. The impact fatigue drop hammer test equipment for alloy parts, through the setting of the drive component and hammer body component, can drive the cam follower and the punch to be lifted by the rotation of the fan-shaped rotating disk, and then make free fall motion.

The fan-shaped rotating disk will continuously push the cam follower to move upward. When the fan-shaped rotating disk rotates to the point where it no longer contacts the cam follower, the punch will fall freely and impact the sample, thereby carrying out the impact test.

Figure 1 , Figure 2 , Figure 5 and Figure 6 The system includes a main frame 1, a drive assembly 2 on the top of the main frame 1, and a circular fixed frame 21 fixedly connected to the upper surface of the main frame 1. The outer surface of the circular fixed frame 21 is provided with a sliding groove 22. The inner wall of the circular fixed frame 21 is rotatably connected to a rotating shaft 23. The outer surface of the rotating shaft 23 is fixedly connected to a fan-shaped rotating disk 24.

[0028] Please refer to this carefully. Figure 1 and Figure 4A hammer assembly 3 is provided above the main frame 1. The hammer assembly 3 includes a lower hammer 32 and a U-shaped frame 31 fixedly connected to the upper surface of the main frame 1. A punch 33 is installed on the bottom surface of the lower hammer 32. A middle guide rod 34 is fixedly connected to the upper surface of the lower hammer 32. An upper hammer 35 is fixedly connected to the outer surface of the middle guide rod 34. The middle guide rod 34 passes through the U-shaped frame 31 and is slidably connected to the U-shaped frame 31. A hammer lifting seat 38 is installed on the outer surface of the middle guide rod 34. The hammer lifting seat 38 is slidably connected to the inner wall of the slide groove 22. A cam follower 39 is fixedly connected to the outer surface of the hammer lifting seat 38. The cam follower 39 is adapted to the fan-shaped rotating disk 24. When the fan-shaped rotating disk 24 rotates, it will continuously push the cam follower 39 to move upward. When the fan-shaped rotating disk 24 rotates to the point where it no longer contacts the cam follower 39, the punch 33 will fall freely.

[0029] Two linear slide rods 36 are fixedly connected to the bottom surface of the upper hammer body 35. The bottom ends of the two linear slide rods 36 are fixedly connected to the upper surface of the lower hammer body 32. The linear slide rods 36 serve to connect and reinforce the lower hammer body 32 and the upper hammer body 35.

[0030] The inner wall of the U-shaped frame 31 is fixedly connected to two symmetrical guide seats 37. Two linear slide rods 36 are slidably connected to the inner walls of the two guide seats 37 respectively. The linear slide rods 36 and the guide seats 37 guide the movement of the lower hammer body 32 and the punch 33.

The fixing component 4 includes a clamp 41 fixedly connected to the upper surface of the main frame 1. A sample 42 is installed on the inner wall of the clamp 41. The sample 42 can be replaced.

[0032] Working principle: After the punch 33 and the sample 42 are installed, the drive motor 25 drives the rotating shaft 23 and the fan-shaped rotating disk 24 to rotate. The fan-shaped rotating disk 24 will continuously push the cam follower 39 to move upward. When the fan-shaped rotating disk 24 rotates to the point where it no longer contacts the cam follower 39, the punch 33 will fall freely and impact the sample 42. The number of impacts and the impact speed are set so that the punch 33 continuously impacts the sample 42 until the set number of impacts is reached and then stops. Alternatively, if the sample 42 is found to break during the impact, the impact can also be stopped. Then the punch 33 and the sample 42 can be replaced for repeated testing.
