Description

Technical Field

[0001] This invention relates to the field of materials testing technology, and in particular to a ball-dropping aid device that adapts to the height of the test sample. Background Technology

[0002] With economic development, materials testing has become an important means of ensuring safety in life. Materials testing includes the analysis, measurement, non-destructive testing, and environmental simulation testing of raw materials. Some tests also involve analyzing the content of environmental pollution and metabolic products in materials such as body fluids, tissues, and excrement to determine the degree of environmental pollution and the risk of harm to the body.

[0003] Currently, in material testing, it is sometimes necessary to test the hardness and strength of samples. Usually, a metal ball is placed at a specified height and allowed to fall freely onto the sample, and the results are then observed. However, the current ball drop test device has a relatively simple structure, and the height of the ball cannot be accurately adjusted according to the height of the sample, which can easily lead to inaccurate test results. Therefore, there is a need for improvement. Summary of the Invention

[0004] This invention provides a convenient and easy-to-use ball-dropping auxiliary device that can adjust the height of the ball according to the height of the test sample, ensuring that the height between the ball and different test samples is always consistent, resulting in more accurate detection. It solves the technical problems of existing ball-dropping detection devices having a simple structure, being unable to adjust the height of the ball according to the height of different test samples, and having inconsistent heights between different test samples and the ball, which affects the detection results.

[0005] The above-mentioned technical problem of the present invention is solved by the following technical solution: a ball-dropping auxiliary device that adapts to the height of the test sample, comprising a test base, a positioning block in the middle of the test base, a height frame on one side of the test base, a height ruler slidingly mounted inside the height frame, a collision ball mounted on the height ruler via a height-adjusting component, the height ruler having graduations, and a zero-gradient alignment component at the bottom of the height ruler. During testing, the sample is placed on the positioning block. First, the height-adjusting component is adjusted to the height of a specified graduation on the height ruler according to requirements. Then, the height of the height ruler is adjusted according to the sample height. The zero-gradient alignment component ensures that the highest point of the sample is aligned with the zero graduation. The collision ball is then placed on the height-adjusting component, and as the collision ball falls freely onto the sample, the result is observed.

[0006] Preferably, the zero-scale alignment component includes a zero-scale laser emitter fixed to the bottom of the height gauge, and the laser emitted by the zero-scale laser emitter indicates the zero-scale position. The zero-scale laser emitter can emit laser light onto the sample, thereby aligning the highest point of the sample with the zero-scale position.

[0007] Preferably, the height-adjusting component includes a ball holder slidably mounted on one side of the height gauge. The ball holder can move with the height gauge, and a collision ball is placed on the ball holder. The end of the ball holder corresponds to a positioning block. The function of the ball holder is to hold the collision ball. The ball holder can move with the height gauge, and its position on the height gauge can be adjusted for easy adjustment as needed.

[0008] Preferably, the ball holder has a through-hole at its end. The ball-dropping hole and the positioning block are located on the same center line, ensuring that the colliding ball falls to the center of the positioning block.

[0009] Preferably, the size of the ball-dropping hole is larger than the size of the colliding ball. The diameter of the ball-dropping hole is larger than the diameter of the colliding ball to ensure that the colliding ball can fall without obstruction.

[0010] Preferably, the ball drop hole is fitted with two arc-shaped limiting plates, and the end of the ball holder is equipped with a switch that cooperates with the limiting plates. During testing, simply place the collision ball in the ball drop hole, manually press the switch, and the limiting plates will quickly retract to both sides, allowing the collision ball to fall freely onto the sample. Finally, the results are observed.

[0011] Preferably, the inner side of the ball frame is equipped with a height laser emitter that emits a laser beam to the height scale. During testing, the sample is placed on the positioning block, and the height of the ball frame is first adjusted to the required position according to the needs. The height laser emitter and the scale are then used for positioning.

[0012] Preferably, the height gauge is provided with sliding grooves on both the front and right sides, and the height gauge and ball frame are slidably installed in the two sliding grooves respectively. The function of the sliding grooves is to facilitate the adjustment of the height gauge and ball frame.

[0013] Preferably, the test stand is equipped with a protective enclosure around its bottom perimeter. The height of the protective enclosure can be set as needed, and its function is to prevent broken samples from scattering.

[0014] Therefore, the ball-dropping auxiliary device of the present invention, which is adaptive according to the height of the test sample, has the following advantages: it is easy to operate and use, and the height of the ball can be adjusted according to the height of the test sample to ensure that the height between the ball and different test samples is always consistent, and the detection structure is more accurate.

A height ruler 6 is installed in the front groove 5 of the height frame 4, and a scale 7 is engraved on the front surface of the height ruler 6. A zero-scale 7 alignment piece is installed at the bottom of the height ruler 6.

[0023] The zero-scale 7 alignment component includes a zero-scale laser emitter 8 fixed to the bottom of the height ruler 6. The laser emitted by the zero-scale laser emitter 8 indicates the position of the zero-scale 7.

[0024] A height-raising component is installed in the right slide groove 5 of the height frame 4. The height-raising component includes a ball frame 9 fixedly installed on the height ruler 6, and the end of the ball frame 9 extends above the positioning block 3.

[0026] Two arc-shaped limiting plates 11 are symmetrically embedded in the ball drop hole 10, and a switch 12 that cooperates with the limiting plate 11 is installed at the end of the ball frame 9.

[0027] An altitude laser emitter 13 that emits lasers toward the height ruler 6 is installed on the inside of the ball frame 9.

[0028] During testing, the sample is placed on the positioning block 3. First, the height of the ball frame 9 is adjusted to the required position according to the needs. The ball frame 9 is then positioned by the height laser emitter 13 and fixed to the height ruler 6 by bolts and other fasteners. Then, the height of the height ruler 6 is adjusted according to the sample height to ensure that the laser emitted by the zero-scale laser emitter 8 is located at the top of the sample. The height ruler 6 is then fixed by bolts and other fasteners.

[0029] During testing, simply place the impact ball inside the ball drop hole 10, manually press the switch 12, and the limit plate 11 will quickly retract to both sides, allowing the impact ball to fall freely onto the sample. Observe the results. The protective enclosure 2 can prevent broken samples from scattering.
