When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present application. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0045] Some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features of the embodiments can be combined with each other.

[0046] See also Figure 1 and Figure 2The present embodiment provides an impact test device 1 for impact testing a product (not shown), and the impact test device 1 comprises a frame 11, a first driving member 12, a first rotating member 13, a second driving member 14, a second rotating member 15, a clamping member 16 and a light emitter 19. The first driving member 12 is connected to the frame 11. The first rotating member 13 is connected to the first driving member 12, and the first driving member 12 is connected to the first rotating member 13 for driving the first rotating member 13 to rotate around the X-axis 121. The second driving member 14 is connected to the first rotating member 13. The second rotating member 15 is connected to the second driving member 14, and can rotate around the Y-axis 141 driven by the second driving member 14, and the X-axis 121 and the Y-axis 141 are perpendicular to each other or obliquely intersecting. The clamping member 16 is used to clamp or release the impact member 17, and the clamping member 16 is connected to the second rotating member 15. The light emitter 19 is used to emit light to the product, and the light emitter 19 is connected to the second rotating member 15.

[0047] After research, it was found that the test device in the prior art has the problem that the ground reference on which the test device is placed is not level, or the assembly accuracy and parts deformation of the test device itself, so the line between the point to be tested of the product and the starting point of the impact part falling is not in the vertical direction, resulting in a positional offset between the point where the impact part falls and hits the surface of the product and the point to be tested. That is, the influence of the test environment or the error of the impact test device itself leads to inaccurate test results. In the prior art, it is difficult to improve by reducing the impact of the environment and improving the accuracy of the test equipment. For example, it is difficult to adjust the ground reference to be completely level, and it is difficult to create zero tolerance for the assembly accuracy and parts deformation of the test device itself.

[0048] The impact testing device 1 of this embodiment improves the shortcomings of the above-mentioned prior art. The first rotating member 13 rotates along the X-axis 121 and the second rotating member 15 rotates along the Y-axis 141 to adjust the clamping member 16 and the light emitter 19 to face the vertical downward direction, and then move the product to the bottom of the light emitter 19 so that the point to be detected and the light spot of the light emitter 19 coincide with each other. Then, the impact member 17 is placed on the clamping member 16, and the clamping member 16 is used to release the impact member 17. The landing point of the impact member 17 after falling coincides with the point to be detected and the light spot. When in use, the impact testing device 1 can not only adjust the impact member 17 to face the vertical downward direction, but also indicate the position of the landing point of the impact member 17 through the light emitter 19. Therefore, the impact testing device 1 can reduce the distance deviation between the impact point and the point to be detected, and improve the accuracy of the test results.

[0049] In this embodiment, the impact member 17 is a spherical body such as a steel ball or a lead ball. The shape of the impact member 17 enables point contact between the impact member 17 and the surface of the product, so the impact member 17 can detect the strength and other properties of the point to be detected on the surface of the product. In other embodiments, the impact member 17 can also be made of other materials or shapes to meet the impact test requirements.

[0050] The X-axis 121 and the Y-axis 141 form a rectangular coordinate system, that is, the X-axis 121 and the Y-axis 141 are perpendicular to each other. The rectangular coordinate system is used to facilitate calculation and adjustment of the first driving member 12 and the second driving member 14, so that the clamping member 16 and the light emitter 19 can rotate around the X-axis 121 and the Y-axis 141, so that the impact member 17 is facing in a vertical downward direction, and at the same time, the light spot irradiated on the surface of the product by the light emitter 19 coincides with the landing point of the impact member 17.

[0051] Please combine Figure 3 and Figure 4 In one embodiment, the clamping member 16 may be an electromagnet, and the impact member 17 may be a magnetic member. The electromagnet is used to be powered on to attract the magnetic member or powered off to release the magnetic member.

[0052] In one embodiment, the surface of the clamping member 16 close to the impact member 17 is concave to form a spherical surface 161 , and the spherical surface 161 fits a portion of the surface of the impact member 17 .

[0053] In this embodiment, the surface of the electromagnet is concave to form a spherical surface 161, and the electromagnet is powered to absorb the impact piece 17, so that the impact piece 17 is fixed in the spherical surface 161, and the spherical surface 161 wraps the surface of the impact piece 17, so that the clamping piece 16 drives the impact piece 17 to adjust its posture. After the impact piece 17 is adjusted, the electromagnet is powered off to release the impact piece 17, so that the impact piece 17 impacts the point to be detected on the surface of the product in the vertical direction.

[0054] Optionally, the spherical surface 161 forms a receiving groove, and the receiving groove accommodates less than half of the volume of the impact member 17. The spherical surface 161 fits with a part of the surface of the impact member 17 to locate the position of the impact member 17. The spherical surface 161 wraps a small part of the surface of the impact member 17 so that the impact member 17 can fall off the spherical surface 161 when the electromagnet is powered off. The spherical surface 161 faces the vertically downward direction. When the impact member 17 falls off from the receiving groove, the edge of the spherical surface 161 will not apply force to the impact member 17, so the spherical surface 161 will not affect the trajectory of the impact member 17 falling along the vertically downward direction.

[0055] Specifically, the accommodating groove can accommodate less than half of the volume of the impact member 17, so that the edge of the spherical surface 161 will not exert force on the impact member 17. At the same time, the larger the contact area between the spherical surface 161 and the surface of the impact member 17, the more conducive it is for the clamping member 16 to provide sufficient magnetic attraction to move the impact member 17, and prevent the moving impact member 17 from detaching from the clamping member 16 during the movement process.

[0056] In one embodiment, the clamping member 16 is provided with an emission port 162, which extends from the middle position of the spherical surface 161 in a direction away from the impact member 17 and passes through the clamping member 16, and the light emitter 19 is connected to the side of the clamping member 16 opposite to the spherical surface 161, and the light emitter 19 is arranged toward the emission port 162.

[0057] Specifically, the light emitted by the light emitter 19 passes through the emission port 162, so the light emitted by the light emitter 19 can propagate in the direction of the clamp 16. When in use, the clamp 16 and the light emitter 19 are first adjusted to face the vertical downward direction, and then the point to be detected on the surface of the product is placed at the light spot position of the light emitter 19, so that the emission port 162, the center of the impact piece 17 and the point to be detected (light spot) of the product are in a straight line, and the impact piece 17 performs free fall motion, so that the impact piece 17 accurately hits the point to be detected after falling.

[0058] When in use, the light emitter 19 plays a guiding role, so that the points to be tested on the surface of the product are marked and visible. The spherical surface 161 accurately locates the position of the impact member 17, and the first rotating member 13 and the second rotating member 15 adjust the posture of the clamping member 16 so that the impact member 17 in the spherical surface 161 faces the vertical downward direction. Therefore, after the clamping member 16 releases the impact member 17, the impact member 17 can accurately hit the point to be tested on the surface of the product, so as to improve the accuracy of the test results of the impact test device 1.

[0059] In one embodiment, the impact testing device 1 also includes an angle sensor 18, which is connected to the second rotating member 15. The angle sensor 18 is electrically connected to the first driving member 12 and the second driving member 14 respectively. The angle sensor 18 is used to sense the angle between the second rotating member 15 and the horizontal plane, and then determine whether the opening of the spherical surface 161 is facing in a vertically downward direction, so as to adjust the rotation angle of the first driving member 12 and the second driving member 14.

[0060] In this embodiment, the angle sensor 18 can be a dual-axis inclination sensor, which can respectively sense the inclination data of the second rotating member 15 around the Y-axis 141 and the inclination data of the first rotating member 13 around the X-axis 121, and the sensing data is used to coordinate the rotation angle of the first driving member 12 and the second driving member 14, so as to adjust the clamping member 16 and the light emitter 19 to rotate to the vertically downward direction, so that the impact member 17 falls along the vertically downward direction to the position of the light spot irradiated on the surface of the product. For example, during debugging, the error between the position of the product to be detected point (light spot) and the actual hitting position of the impact member 17 is measured, and according to the error indication, the first driving member 12 and the second driving member 14 drive the first rotating member 13 and the second rotating member 15 to rotate, and adjust to a state where the impact member 17 can accurately hit the light spot.

[0061] In one embodiment, the first rotating member 13 includes a first connecting portion 131 and a first ear portion 132 connected to each other, the first connecting portion 131 is connected to the first driving member 12, and the first ear portion 132 extends from the first connecting portion 131 along the X-axis 121 in a direction away from the frame 11. The second rotating member 15 includes a second connecting portion 151 and a second ear portion 152 connected to each other, the second ear portion 152 is opposite to the first ear portion 132 along the Y-axis 141, the second driving member 14 is connected between the first ear portion 132 and the second ear portion 152, the second connecting portion 151 extends along the X-axis 121 in a direction away from the frame 11, the second driving member 14 can drive the second rotating member 15 to rotate relative to the first rotating member 13, and the light emitter 19 and the clamping member 16 are connected to the second connecting portion 151.

[0062] In this embodiment, the first ear portion 132 and the second ear portion 152 may be handle-shaped to increase the contact area between the first ear portion 132 and the second ear portion 152 and the second driving member 14 , thereby improving the rotation stability of the second driving member 14 .

[0063] In one embodiment, the first driving member 12 and the second driving member 14 are disposed on the X-axis, and the first ear portion 132 and the second ear portion 152 are disposed on both sides of the X-axis.

[0064] In this embodiment, the first driving member 12 and the second driving member 14 are coaxially arranged so that the second driving member 14 can rotate around the X-axis through the first driving member 12, and the second driving member 14 itself can rotate around the Y-axis, so the second rotating member 15 can rotate around the second driving member 14, and the X-axis and the Y-axis intersect at the second driving member 14.

[0065] In one embodiment, the frame 11 includes a lifting arm 111 and a fixing seat 112 . The lifting arm 111 is movably connected to the fixing seat 112 along a height direction. The lifting arm 111 is connected to the first driving member 12 .

[0066] In this embodiment, the light emitter 19 can use a laser distance sensor, and the light emitter 19 can emit light to indicate the landing point, and can also detect the distance between the landing point of the impact member 17 and the launch port 162. The light emitter 19 is electrically connected to the lifting cantilever 111, and the light emitter 19 obtains distance data for adjusting the lifting cantilever 111 to a suitable height.

[0067] In one embodiment, the impact testing device 1 further includes a control module 2, which is electrically connected to the first driving member 12 and the second driving member 14, respectively, for controlling the first driving member 12 and the second driving member 14 to operate so that the clamping member 16 faces a vertical downward direction.

[0068] Optionally, the angle sensor 18 is electrically connected to the control module 2 , and is used to sense whether the clamping member 16 is facing a vertically downward direction. The control module 2 adjusts the rotation angles of the first driving member 12 and the second driving member 14 according to the sensing signal of the angle sensor 18 .

[0069] The light emitter 19 is electrically connected to the control module 2 . The light emitter 19 is used to detect the distance between the landing point of the impact piece 17 and the emission port 162 . The control module 2 adjusts the height of the lifting cantilever 111 according to the sensing signal of the light emitter 19 .

[0070] In summary, the impact testing device 1 controls the first rotating member 13 to rotate along the X-axis 121 and the second rotating member 15 to rotate along the Y-axis 141 through the control module 2 to adjust the clamping member 16 and the light emitter 19 to face the vertical downward direction. Therefore, when the impact member 17 falls, the impact member 17 can accurately impact the point to be detected (light spot) on the surface of the experimental product in the vertical direction to improve the accuracy of the test results of the impact testing device 1.

Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
