[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 This utility model discloses an adjustable drop test device for metal components, including a support base 1, and a vertical drop test component 2, a spill drop test component 3, and an adjustable drop impact table component 4 installed on the top of the support base 1.

[0028] The vertical drop test assembly 2 includes four guide rods 21 fixed to the top of the support base 1. A movable frame 22 is slidably connected to the surface of two corresponding guide rods 21. A placement base 23 is fixed between the two movable frames 22. Two limiting plates 24 are slidably connected to the placement base 23. A drive mechanism 25 is provided on the placement base 23 to drive the two limiting plates 24 to move synchronously in opposite directions. A top plate 26 is fixed to the top of the four guide rods 21. A lifting mechanism 27 for driving the placement base 23 to move up and down is installed on the top plate 26.

[0029] Specifically, the drive mechanism 25 includes a rotating shaft 251 rotatably connected to the top of the placement seat 23 via bearings. A gear 252 is fixed on the surface of the rotating shaft 251. A rack 253 is fixed on one side wall of the limiting plate 24. The rack 253 is meshed with the gear 252. A motor 254 is fixed on the top of the placement seat 23. The output end of the motor 254 is fixedly connected to the top of the rotating shaft 251.

[0030] In this embodiment, after the motor 254 is started, it will drive the rotating shaft 251 to rotate. At this time, the gear 252 fixed on the surface of the rotating shaft 251 can rotate synchronously. Since the gear 252 meshes with the rack 253 on the two limit plates 24, it drives the two limit plates 24 to move synchronously in opposite directions along the placement seat 23. The motor 254 has a self-locking function.

[0031] Specifically, the top of the placement seat 23 has two T-slots 255, and the bottom of the rack 253 is fixed with T-shaped rods 256 that are compatible with the T-slots 255.

[0032] In this embodiment, when the rack 253 moves with the limiting plate 24, the T-shaped rod 256 at the bottom of the rack 253 slides in the T-shaped groove 255 at the top of the placement seat 23, thereby guiding and limiting the movement of the rack 253.

[0033] Specifically, the lifting mechanism 27 includes two connecting plates 271 fixed to the top of the top plate 26. The side walls of the connecting plates 271 are rotatably connected to rotating rods 272 via bearings. Steel wire rope rollers 273 are fixed to the surface of the rotating rods 272. One end of the steel wire rope on the two steel wire rope rollers 273 slides through the top plate 26 and extends below it, and is fixedly connected to the corresponding moving frame 22. A dual-axis motor 274 is fixed to the top of the top plate 26. One end of the rotating rods 272 is fixedly connected to the output end of the dual-axis motor 274.

[0034] In this embodiment, the dual-axis motor 274 will start and drive the rotating rod 272 to rotate. At this time, the wire rope roller 273 fixed on the surface of the rotating rod 272 can rotate synchronously. When the wire rope roller 273 retracts or extends the wire rope, it can pull the moving frame 22 to move up and down along the guide rod 21, thereby driving the placement seat 23 to rise and fall. The dual-axis motor 274 is a servo motor with a self-locking function.

[0035] Specifically, the drop test assembly 3 includes a guide seat 31 fixed to the top of the support seat 1. A drive shaft 32 is rotatably connected between the inner walls of the two sides of the guide seat 31 via bearings. A flipping frame 33 is fixed to the surface of the drive shaft 32. A second motor 34 is fixed to one side wall of the guide seat 31. The output end of the second motor 34 is fixedly connected to one end of the drive shaft 32.

[0036] In this embodiment, after the second motor 34 is started, it will drive the drive shaft 32 to rotate. At this time, the flipping frame 33 fixed on the surface of the drive shaft 32 can be flipped synchronously. Then, the metal component placed in the flipping frame 33 can be thrown out in a parabolic trajectory as the flipping frame 33 is flipped. The second motor 34 has a self-locking function.

[0037] Specifically, the inner walls on both sides of the guide seat 31 are provided with arc-shaped grooves 35, and the two sides of the flipping frame 33 are fixed with sliders 36 that are adapted to the arc-shaped grooves 35.

[0038] In this embodiment, when the tilting frame 33 tilts, the sliders 36 on its two side walls slide in the arc grooves 35 on the inner walls of the guide seat 31, thereby providing guidance and support for the tilting frame 33 when it tilts.

[0039] Specifically, the adjustable drop impact table assembly 4 includes two electric push rods 41 fixed to the top of the support base 1. A horizontal plate 42 is fixed to the top end of the two electric push rods 41. A bearing plate 43 is fixed to the top of the horizontal plate 42. Tabletop 1 44, tabletop 2 45 and tabletop 3 46 are fixed to the top of the bearing plate 43 in sequence.

[0040] In this embodiment, the extension and retraction of the electric push rod 41 can drive the horizontal plate 42 to move, thereby allowing the support plate 43 fixed on the top of the horizontal plate 42 to move left and right. The platform 1 44, platform 2 45 and platform 3 46 on the support plate 43 move with the support plate 43, realizing the switching of different platforms. The two electric push rods 41 are arranged opposite to each other. When the extension end of one electric push rod 41 retracts, the extension end of the other electric push rod 41 will continue to push out. In the figure, the extension length of its extension end is not at its maximum, and the electric push rod 41 has a self-locking function.

[0041] Specifically, countertop 1 (44) is a concrete countertop, countertop 2 (45) is a wooden countertop, and countertop 3 (46) is a steel plate countertop.

[0042] In this implementation plan, platform 1 (44), platform 2 (45), and platform 3 (46) are made of concrete, wood, and steel respectively. When the metal component is dropped, the different materials of the platform will produce different impact effects on the metal component, and can be selected and switched according to the test needs.

[0043] Specifically, the top of the support base 1 is fixed with two guide rails 47, and the bottom of the bearing plate 43 is fixed with two guide rods 48 that are compatible with the guide rails 47.

[0044] In this embodiment, the guide rod 48 at the bottom of the support plate 43 slides within the guide rail 47 at the top of the support base 1, thereby guiding the movement of the support plate 43.

[0045] Specifically, two support rods 5 are fixed to the top of the support base 1, and a protective plate 6 is hinged to one side wall of each support rod 5.

[0046] This implementation plan provides safety protection for the testing process, protects the safety of operators and the surrounding environment, avoids accidental injuries caused by falling and splashing components, and improves the safety of the device. During testing, for effective protection, personnel should not stand on the sides or back of the device. Limiting buckle structures are set on the two protective plates 6. When the two protective plates 6 are closed, they can be fixedly connected. However, the limiting buckle structure is not shown in the figure.

[0047] The working principle and usage process of this utility model are as follows: When a metal component needs to undergo a vertical drop test, it is placed on top of the two limiting plates 24 on the placement base 23. Then, when the dual-axis motor 274 starts, it drives the rotating rod 272 to rotate. This causes the wire rope roller 273, fixed to the surface of the rotating rod 272, to rotate synchronously. When the wire rope roller 273 retracts or extends the wire rope, it pulls the moving frame 22 up and down along the guide rod 21, thereby raising and lowering the placement base 23. After the seat 23 is adjusted to the required drop height, the motor 254 is started to drive the rotating shaft 251 to rotate. This causes the gear 252 fixed to the surface of the rotating shaft 251 to rotate synchronously. Because the gear 252 meshes with the racks 253 on the two limiting plates 24, it drives the two limiting plates 24 to move synchronously and rapidly in the opposite direction along the seat 23. After releasing the restriction on the metal component, the metal component will then fall freely vertically, thus completing the vertical drop test. When the metal component needs to undergo a drop test, the metal... When the metal component is placed inside the flipping frame 33, the second motor 34 starts and drives the drive shaft 32 to rotate. At this time, the flipping frame 33, which is fixed on the surface of the drive shaft 32, can rotate synchronously. Then, the metal component placed inside the flipping frame 33 can be thrown out in a parabolic trajectory as the flipping frame 33 rotates. The metal component is thrown and falls on the test platform, which can simulate the scenario of metal component being thrown and falling. During the test, when test platforms of different hardness are used as needed, the extension and retraction of the top end of the electric push rod 41 can drive the horizontal plate 42 to move. This allows the support plate 43, which is fixed on the top of the horizontal plate 42, to move left and right. The platform 1 44, platform 2 45, and platform 3 46 on the support plate 43 move with the support plate 43, realizing the switching of different platforms. In addition, the height adjustment of the placement seat 23 is achieved by a displacement sensor, and monitoring and data recording can be achieved by a sensor or data acquisition instrument. The data can be displayed through an intelligent control panel. Since this is existing technology, it will not be described in detail here.

[0048] In summary, this adjustable drop test device for metal components solves the problems of existing drop test devices having limited functionality and being unable to quickly change the platform with different hardness according to needs.
