[0031] Reference Figure 1-6 The utility model provides a drop ball impact tester for quickly loading a steel ball, comprising a frame 1, a drop ball mechanism 2 and a lifting mechanism 3. The frame 1 is fixed on a workbench, and the drop ball mechanism 2 and the lifting mechanism 3 are both installed.

[0032] On the frame 1 , the ball drop mechanism 2 can be used to drop a steel ball onto the test piece to complete the ball drop impact test, and the lifting mechanism 3 can lift the dropped steel ball back to the ball drop mechanism 2 for the next ball drop test.

[0033] The frame 1 includes a bottom plate 11, a crossbeam 12 and two longitudinal beams 13. The bottom plate 11 and the crossbeam 12 are fixed between the two longitudinal beams 13. The bottom plate 11 and the crossbeam 12 are respectively located at the upper end and the lower end of the longitudinal beam 13. Mounting plates 14 can be fixed on both sides of the longitudinal beam 13 for fixing to the workbench.

[0034] The ball-dropping mechanism 2 includes a ball-dropping tube 21 and a ball-holding assembly 22. Two vertically positioned slide bars 15 are fixed to the interior of the frame. The slide bars 15 are secured between the base plate 11 and the crossbeam 12. A first sliding plate 16 and a second sliding plate 17 are also provided within the frame. The ball-dropping tube 21 is vertically positioned and secured to the first and second sliding plates 16, 17. The first and second sliding plates 16, 17 are capable of vertical movement to adjust the position of the ball-dropping tube 21. It should be noted that the ball-dropping tube 21 can be secured to the first and second sliding plates 16, 17 via a holding rod. This is prior art and will not be further elaborated in this application. A fixed frame 18 is fixed inside, and the slide rod 15 is installed through the fixed frame 18. The first sliding plate 16 is located above the fixed frame 18, and the second sliding plate 17 is located below the fixed frame 18. A first screw 181 is rotatably connected to the lower part of the frame corresponding to the fixed frame 18. The first screw 181 is vertically arranged and threadedly connected to the second sliding plate 17. The rotation of the first screw 181 can drive the second sliding plate 17 to move up and down. The up and down movement of the second sliding plate 17 can drive the ball drop tube 21 and the first sliding plate 16 to move up and down. A first servo motor 182 is fixed to the upper side of the fixed frame 18. The output shaft of the first servo motor 182 extends into the fixed frame 18 and is fixed to the first screw 181, thereby driving the first screw 181 to rotate and adjust the height of the ball drop tube 21.

[0035] The ball holding assembly 22 includes a fixed plate 221, a two-way cylinder 222 and two ball holding racks 223. The fixed plate 221 is fixed to the top of the frame, and the fixed plate 221 is located above the ball drop tube 21. Specifically, the fixed plate 221 is fixed to the top of the first sliding plate 16, and the two-way cylinder 222 is fixed to the fixed plate 221, so that the two-way cylinder 222 can be set above the ball drop tube 21. The two ball holding racks 223 are arranged relative to each other, and the arrangement direction of the two ball holding racks 223 is the same as the length direction of the two-way cylinder 222. The two telescopic rods of the two-way cylinder 222 are respectively fixed to the two ball holding racks 223. When the two-way cylinder 222 is working, it can drive the two ball holding racks 223 to move in opposite directions, that is, the two ball holding racks 223 can move towards each other to reduce the gap between them, thereby dragging the steel ball, and can also move away from each other to drop the steel ball.

[0036] During operation, the steel ball can be dragged by the two ball holding racks 223 moving relative to each other, and the two ball holding racks 223 move away from each other, allowing the steel ball to fall into the ball drop tube 21, thereby being used for steel ball testing. When the first servo motor 182 is in operation, it can drive the first screw 181 to rotate, thereby driving the first sliding plate 16, the second sliding plate 17, the ball drop rod and the ball holding assembly 22 to move up and down synchronously, thereby adjusting the height of the steel ball drop and improving the applicability of the steel ball testing equipment.

[0037] The lifting mechanism 3 includes a second screw 31, a vertically movable beam 32, a second servo motor 33, and a rotating block 34. The vertically movable beam 32 is mounted on one side of the frame and is vertically slidably connected to the ball-dropping mechanism 2. The second screw 31 is vertically mounted and rotationally connected to one side of the ball-dropping mechanism 2. The vertically movable beam 32 has a vertically threaded through-hole into which the second screw 31 is threaded. Rotation of the second screw 31 drives the vertically movable beam 32 up and down, reciprocating between above and below the ball-dropping mechanism 2.

[0038] The second servo motor 33 is fixed to the side of the vertical moving beam 32 near the ball drop tube 21. The output shaft of the second servo motor 33 is fixed to the rotating block 34. A receiving groove 341 for placing steel balls is provided above the rotating block 34. The receiving groove 341 is open on the side near the ball drop mechanism 2. The second servo motor 33 is able to drive the rotating block 34 to rotate, thereby flipping the steel ball and dropping it from the receiving groove 341 to between the two ball holding racks 223. A third servo motor 35 is fixed to one side of the ball drop mechanism 2. The output shaft of the third servo motor 35 is fixed to the second screw 31. When the third servo motor 35 is in operation, it can drive the second screw 31 to rotate, thereby driving the rotating block 34 to move up and down.

[0039] When using the drop ball impact testing machine of the present application, after the steel ball falls and completes the drop ball test, the staff can place the fallen steel ball in the receiving groove 341 below. As the third servo motor 35 works, it can drive the second screw 31 to rotate, thereby driving the vertical moving beam 32 to drive the rotating block 34 to move upward, thereby driving the rotating block 34 to reach the ball holding assembly 22. The second servo motor 33 drives the rotating block 34 to rotate, flipping the steel ball from the receiving groove 341 and discharging it between the two ball holding racks 223, so as to prepare for the next steel ball test, avoiding the staff from frequently bending over to pick up the ball and then standing up to place the fallen ball, reducing the staff's work pressure, improving work efficiency, and facilitating continuous work.

[0040] As an embodiment, the lifting mechanism 3 also includes a vertical plate 36, which is fixed to the first sliding plate 16 and the second sliding plate 17. The second screw 31 is rotatably connected to one side of the vertical plate 36, and the vertical moving beam 32 is slidably connected to the vertical plate 36. The movement of the first sliding plate 16 and the second sliding plate 17 will also drive the vertical plate 36 to move together, thereby enabling the lifting mechanism 3 and the ball falling mechanism 2 to move up and down synchronously.

[0041] As an embodiment, a first driving cylinder 161 is fixed on the upper side of the first sliding plate 16, the first driving cylinder 161 is vertically arranged, the fixed plate 221 is fixed to the telescopic rod of the first driving cylinder 161, and the movement of the first driving cylinder 161 can fine-tune the height of the two ball holding racks 223.

[0042] As an embodiment, a second driving cylinder 23 is fixed to the side of the fixed plate 221 away from the frame, and a limit block 24 is fixed downwardly on the telescopic rod of the second driving cylinder 23. A spherical groove 241 is provided on the lower side of the limit block 24. The limit block 24 is located on the upper side of the two ball holding racks 223. When the steel ball is located between the two ball holding racks 223, the second driving cylinder 23 can drive the limit block 24 to move downward, thereby limiting the position of the steel ball, so that the steel ball can fall stably into the ball drop tube 21.

[0043] Furthermore, a top block 211 is fixed to the upper end of the ball drop tube 21. A through slot 2111 is defined in the middle of the top block 211. The through slot 2111 communicates with the ball drop tube 21. The axis of the through slot 2111 is aligned with the axis of the ball slot 241. The steel ball can enter the ball drop tube through the through slot 2111, further preventing the steel ball from falling and deviating.

[0044] The working principle of the present invention is as follows: during operation, the steel ball can be dragged by the two ball holding racks 223 moving relative to each other, and the two ball holding racks 223 move in a direction away from each other, so that the steel ball can fall and be adjusted into the ball drop tube 21, thereby being used for steel ball testing. After the steel ball falls and completes the ball drop test, the staff can place the fallen steel ball in the receiving groove 341 below. As the third servo motor 35 works, it can drive the second screw 31 to rotate, thereby driving the vertical moving beam 32 to drive the rotating block 34 to move upward, thereby driving the rotating block 34 to reach the ball holding assembly 22. The second servo motor 33 drives the rotating block 34 to rotate, flipping the steel ball from the receiving groove 341 and discharging it between the two ball holding racks 223, so as to be ready for the next steel ball test. This avoids the staff from frequently bending down to pick up the ball and then standing up to place the fallen ball, thereby reducing the staff's work pressure, improving work efficiency, and facilitating continuous work.

[0045] Those skilled in the art will appreciate that, provided there is no conflict, the above preferred solutions can be freely combined and superimposed.

[0046] It should be understood that the above-mentioned embodiments are merely illustrative and non-restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
