Its main technical advantages are: convenient operation, ability to clamp samples of different thicknesses, and the capacity to perform comparative testing of multiple samples under the same environment.

[0004] Traditional steel ball impact testing methods have significant technical drawbacks: steel balls are prone to rebound after impacting the plate, and without an effective interception mechanism, multiple uncontrolled impacts can occur, seriously affecting the accuracy of test data. To solve the above problems, we provide an automatic steel ball impact testing machine. Utility Model Content

[0005] The purpose of this invention is to provide an automatic steel ball impact testing machine to solve the problem mentioned in the background art that steel balls easily rebound after impacting the plate, and if there is no effective interception mechanism, multiple uncontrolled impacts will occur, which seriously affects the accuracy of the test data.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic steel ball impact testing machine, including a enclosure base, a lifting mechanism is provided on the top of the enclosure base, an impact mechanism is provided on the front of the lifting mechanism, a limit mechanism is provided at the bottom of the impact mechanism, and a control cabinet is placed on one side of the enclosure base.

A threaded shaft is rotatably connected inside the square tube column via bearings. A first motor is bolted to the top of the square tube column. The output end of the first motor is bolted to the threaded shaft via a coupling. A connecting tube is sleeved on the surface of the threaded shaft. Threaded sleeves are fixedly sleeved at both ends of the connecting tube. The inside of the threaded sleeves is threadedly connected to the threaded shaft. Slider blocks are bolted to both sides of the connecting tube. A slide rail adapted to the slider is bolted inside the square tube column. One side of the slider is slidably connected to the slide rail.

[0008] The impact mechanism includes a housing, a sleeve bolted to the bottom of the housing, a bracket bolted to the inside of the housing, a second motor bolted to the top of the bracket, a winding wheel bolted to the output end of the second motor via a coupling, the other end of the winding wheel being rotatably connected to the housing via a bearing, a first steel wire rope wound on the surface of the winding wheel, an electromagnet chuck bolted to the other end of the first steel wire rope, and a steel ball attracted to the bottom of the electromagnet chuck.

[0009] Preferably, the limiting mechanism includes a connecting plate, the top of which is bolted to the chassis, the bottom of which is bolted to a base plate, the back of which is bolted to a second connecting block, the back of which is bolted to a connecting pipe, the front of which has a first through groove adapted to the second connecting block, the inside of which has a sliding groove, a limiting plate slidably connected, the inside of which has a through hole, the bottom of which communicates with the through hole, the top of which has a sensor bolted to, the surface of which has a round hole adapted to the sensor, the front of which has a cylinder bolted to, the telescopic end of which has a second steel wire rope bolted to, the top of which has a pulley bolted to, the top of which has a square hole adapted to the pulley, and the other end of which is fixedly connected to the limiting plate.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This device automatically releases and retrieves the steel ball. When the sensor detects the steel ball passing through twice within a set time, it triggers the cylinder to actuate. This releases the second steel wire rope, causing the spring to reset and pushing the sliding sleeve to slide on the sliding rod. This, in turn, causes the limit plate to quickly seal the through hole, effectively preventing the steel ball from falling again due to rebound and avoiding distortion of test data. At the same time, the second motor drives the winding wheel to release or retract the first steel wire rope. Combined with the adsorption function of the electromagnet chuck, this achieves rapid reset of the steel ball, significantly improving test efficiency. It not only facilitates the control of the number of impacts but also has high practicality and promotional value. Attached Figure Description

[0027] Brief description of the usage process: The user can place the test plate on top of the enclosure base 1, and start the first motor 203 to drive the threaded shaft 202 to rotate. The threaded shaft 202, through the engagement of the threaded sleeve 205, drives the connecting pipe 204 to move. At the same time, the connecting pipe 204 drives the slider 207 to slide on the surface of the slide rail 206. The first connecting block 208 and the second connecting block 209 drive the impact mechanism 3 and the limiting mechanism 4 to move up and down. The first connecting block 208 and the second connecting block 209 can slide smoothly inside the first through groove, thereby effectively facilitating the adjustment of the impact height. The control cabinet 5 controls the electromagnet chuck 307 to disconnect from the steel ball 308, causing the steel ball 308 to fall and conduct an impact test on the plate. The sensor 406 senses the steel ball 308. When the sensor 406 detects the steel ball 308 for the second time within the set time, The cylinder 407 extends its telescopic end, simultaneously releasing the tension on the second wire rope 408. Then, the spring 414 resets, pushing the sliding sleeve 413 to slide on the surface of the sliding rod 411. The sliding sleeve 413, through the connecting rod 415, drives the limiting plate 404 to block the through hole 405, causing the steel ball 308 to fall onto the top of the limiting plate 404. Subsequently, the second motor 304 reverses, driving the winding wheel 305 to rotate, allowing it to unwind the first wire rope 306. Then, the electromagnet chuck 307 activates to attract the steel ball 308. Afterward, the second motor 304 reverses again to wind up the first wire rope 306, lifting the steel ball 308. This effectively controls the number of impacts and prevents the steel ball 308 from rebounding and falling again, thus avoiding inaccurate test data. It also allows for rapid reset of the steel ball 308 and enables repeated impact tests.
