The sample can be continuously subjected to the impact test, and particularly relates to a glass impact test apparatus that can be subjected to the impact test by rotating the sample at various angles through the angle adjustment unit.

In general, the impact test apparatus performs an impact test to determine whether the damage of the sample is caused by the amount of impact caused by free fall of the hammer while the sample is mounted on the vise and the hammer is raised to a certain height.

However, since the impact test through the general impact test apparatus does not accurately measure the amount of impact generated through the hammer, the impact amount is formed within a predetermined range rather than the exact value, and thus the reliability of the impact test is deteriorated.

In particular, it has been pointed out that the problem that the workability is remarkably lowered is that most of the structures can test a single sample.

The present invention for solving the above problems is a main body including a base; A drive motor configured at an upper end of the main body; An arm connected to the drive motor and the rotating shaft, a hammer formed at the end of the arm, and an impact sensor formed at a rear end of the hammer to measure the impact strength of the hammer; A sample fixing part mounted on the base of the main body; And a control unit connected to the driving motor, the striking unit, and the sample fixing unit to control each component, and configured to display the impact value extracted from the impact sensor of the striking unit.

At the end of the rotary shaft coupled to the arm of the striking unit in the present invention is characterized in that the encoder is further formed to measure the rotation angle of the arm of the striking unit.

The main body of the present invention is further characterized by a clamp cylinder for fixing the arm.

In the present invention, the sample holding part includes a sample transfer motor on one side, and a drive shaft driven by the sample transfer motor is formed, and a vise for fixing the sample is formed on the upper side of the drive shaft. It is characterized in that the angle adjuster is configured to adjust the angle of the sample.

The present invention can improve the reliability of the impact test by extracting the exact value of the impact value by the impact sensor directly connected to the hammer hitting the sample.

In addition, by checking the rotation angle of the hitting portion by the encoder, the impact test of the sample according to the impact value desired by the user can be carried out.

In addition, a plurality of samples can be continuously impact tested through a sample transport motor formed in the sample fixing part, and in particular, it is a useful design that allows the impact test by rotating the sample at various angles through the angle adjusting unit.

Next, the striking part 10 is formed with an arm 11 connected by a driving motor M and a rotating shaft S coupled to the main body H, and at the end of the arm 11. The hammer 12 which can strike a sample is comprised, The impact sensor 13 is attached between the arm 11 and the hammer 12. As shown in FIG.

The impact sensor 13 is typically configured in the form of a load cell for detecting a load value.

Next, the sample fixing unit 20 is configured to be mounted on the base B of the main body H to fix the sample.

The sample fixing part 20 is configured with a sample feeding motor 21 on one side, and the driving shaft 22 and the driving shaft 22 connected to the sample feeding motor 21 operate by a motor. It consists of a vise 23 for moving and mounting a sample.

In particular, the vise 23 is provided with an angle adjusting unit 23a capable of rotating the sample at various angles after fixing the sample is configured to be subjected to an impact test at various angles through the striking unit 20.

In the present invention, the clutch 30 is further formed on the driving motor M to be configured to brake the striking part 10.

In addition, the encoder (E) is further installed at the end of the rotation shaft (S) connecting the drive motor (M) and the striking portion 10 is configured to measure the rotation angle of the striking portion (10).

At this time, the rising position of the hitting portion 10 is raised to a position that can obtain as much as the impact value required for the impact test of the sample.

This is, until the impact value required by the user is formed through the control unit C and the encoder E while the impact value according to the position of the hitting unit 10 is input through the initial control unit C. It can be moved through the drive motor (M).

If the striking portion 10 is raised to 90 ° in the present invention, the arm 11 may be fixed through the clamp cylinder 40.

On the other hand, the impact portion 10 rotated and raised by the drive motor M as described above is braked to prevent rotation by the clutch 30 formed in the main body (H).
