Description

Falling ball experiment testing device

Technical Field

The utility model relates to a testing arrangement especially relates to a numerical control ball falling experiment testing arrangement.

Background

The falling ball falling impact damage test is a simple, direct and effective test method for the capability of bearing external impact damage to the thin plate toughened glass at present. The falling ball experiment method generally used at present realizes the test by manually lifting the falling ball device to a certain height to release the falling ball, so that the defects of high working strength, easy fatigue of personnel and large positioning error of the falling ball height are caused, and finally, the accuracy of the test result data is greatly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a light realization repeated impact destroys experiment and little ball experiment testing arrangement that falls of repeated positioning accuracy error is provided.

The utility model provides a technical scheme that technical problem adopted is: the ball falling experiment testing device comprises a base, a testing seat and a numerical control linear motion device, wherein the testing seat is arranged on the base, and a groove is formed in the testing seat; the numerical control linear motion device comprises a servo motor, a linear module, a sliding block, an electromagnet seat, an electromagnet and a steel ball, wherein the servo motor drives a transmission device in the linear module to move; the steel ball is positioned above the test seat.

Furthermore, adjusting support feet are respectively arranged below 4 corners of the base.

Furthermore, the groove in the test seat is designed into a corresponding shape according to the appearance shapes of different glass to be tested.

The utility model has the advantages that: because the numerical control linear motion device is arranged, repeated impact damage experiments with fixed height and high height can be easily realized, the repeated positioning precision error is extremely small, the automatic test device has the characteristics of higher automation degree, simple operation and reliable test, and the labor intensity of testers is greatly reduced.

Detailed Description

The utility model discloses a falling ball experiment testing arrangement includes base 1, test seat 2 and numerical control linear motion device 3, wherein, is provided with adjustment stabilizer blade 11 respectively under 4 angles on base 1, and adjustment stabilizer blade 11 can adjust the level of testing arrangement, guarantees test quality; the test seat 2 is arranged on the base 1, a groove 21 is arranged in the test seat 2, and the glass 4 to be tested is placed in the groove 21; the numerical control linear motion device 3 comprises a servo motor 31, a linear module 32, a sliding block 33, an electromagnet seat 34, an electromagnet 35 and a steel ball 36, wherein the servo motor 31 drives a transmission device in the linear module 32 to move, the sliding block 33 is arranged on the linear module 32, the transmission device in the linear module 32 drives the sliding block 33 to move up and down, the electromagnet seat 34 is arranged on the sliding block 33, the electromagnet 35 is arranged on the electromagnet seat 34, and the electromagnet 35 sucks the steel ball 36; steel ball 36 is positioned above test seat 2.

The groove 21 in the test socket 2 can be designed into a groove 21 with a corresponding shape according to the appearance shape of different glass 4 to be tested, so as to better position different glass 4 to be tested.

Adopt the utility model discloses a device height-fixing test method does:

firstly, the tested glass 4 is placed in the groove 21 in the test seat 2, the power is on, the electromagnet 35 sucks the steel ball 36, the servo controller controls the servo motor 31 to rotate, the transmission device in the linear module 32 drives the sliding block 33 to ascend, the sliding block 33 drives the electromagnet seat 34 to ascend the steel ball 36 to the test height, the power of the electromagnet 35 is off after the steel ball 36 reaches the test height, the steel ball 36 falls down and hits on the tested glass 4, and the first hit test is completed. At the moment, the sliding block 33 is positioned at the height and is repeatedly powered on and off, the electromagnet 35 repeatedly sucks and discharges the steel ball 36 to hit the glass 4 to be tested until the glass 4 to be tested is broken, the testing height and the hitting times are recorded, and the test is completed.

Adopt the utility model discloses a device becomes height test method does:

similar to the fixed-height test, the servo controller controls the servo motor 31, so that the sliding block 33 firstly rises to the lowest test height and releases the steel ball 36 during the first impact test to complete the first impact test, and then the sliding block 33 is controlled to rise at a fixed set height and release the steel ball 36 to impact the tested glass 4 every time until the tested glass 4 is broken at a certain height, the test height is recorded, and the test is completed.
