Description

Technical Field

[0001] This utility model relates to the technical field of impact testing machine equipment, and in particular to a three-in-one fully automatic three-in-one impact testing machine. Background Technology

[0002] Impact performance testing is a crucial step in many fields, including materials science, product engineering, and quality inspection. It effectively assesses key performance indicators such as impact resistance, toughness, and brittleness of materials or products under impact loads, providing a scientific basis for material selection, product design optimization, and quality control. However, most impact testing equipment on the market today is single-function and struggles to meet diverse testing needs. This not only limits testing efficiency but also increases equipment procurement costs for companies.

[0003] The shortcomings of existing technology and equipment include: 1. Functional limitation: Existing testing machines can only perform one specific impact test method and cannot meet other testing needs. In actual production, companies often need to conduct multiple impact performance tests on materials or products, which leads to the need to purchase multiple different types of testing machines, increasing not only equipment purchase costs but also the floor space and maintenance costs. 2. Low testing efficiency: Due to the limited functionality of the equipment, frequent machine changes are required when different tests are needed, which greatly reduces testing efficiency. Moreover, the operating procedures and data recording methods of different testing machines may differ, increasing the operational difficulty and training costs for testing personnel. 3. Limitations in impact force measurement accuracy and control: In some application scenarios, the requirements for precise control and measurement accuracy of impact force are increasingly high. Existing single-function testing machines have certain limitations in impact force measurement accuracy and control, and cannot meet some high-precision testing needs.

[0004] Therefore, there is an urgent need for a fully automatic three-in-one impact testing machine that is simple in structure, easy to operate, can meet multiple tests at the same time, has stable performance, and reduces enterprise costs. Summary of the Invention

[0035] The controller 6 is communicatively connected to the lifting device group 2, the ball dropping device 3, the pen dropping device 4, and the impact force value device 5.

[0036] A fully automatic three-in-one impact testing machine also includes a housing (not shown), which is an acrylic transparent cover and is disposed outside the testing machine 100.

[0037] This equipment is mainly used for automatic ball and pen impact testing of various materials, finished products, glass, LCD displays and other products. It uses computer software monitoring and infrared alignment device to strike the product with a steel ball of a certain weight, and can display the impact force curve.

[0038] When in use, the ball-dropping device 3 places the sample to be tested on the XY-axis moving platform 31, automatically moving and positioning the test point along the XY-axis. The coordinates of the test point can be set on the controller 6, and impact energy data (the weight of the ball, the self-fall control mode, and the calculated drop height) can be input into the controller 6. The controller 6 controls the movement of the XY-axis moving platform 31 in the X and Y axes, and the first laser positioner 322 performs positioning. When it moves to the corresponding position, the controller 6 controls the first lifting device 21 to lift the first ball-attracting electromagnet device. 323 is raised to a set height, and then the first ball 3232 on the first ball-attracting electromagnet device 323 is controlled to fall automatically. During the falling process, the first clamping box 332 is opened by the drive cylinder 3322, and the first ball 3232 passes between the two halves of the box 3321. After the first ball 3232 falls on the sample to be tested once, it bounces back. At the same time, the drive cylinder 3322 controls the two halves of the box 3321 to close and catch the rebounding first ball 3232, so as to avoid the first ball 3232 impacting the sample a second time, and realize the data acquisition of the impact force of the sample.

[0039] When the pen-dropping device 4 is in use, the sample to be tested is placed on the test point on the stage 41, and the impact energy data (the weight of the pen, the self-fall control mode, and the pen drop height) is input into the controller 6. The second laser positioner 424 is used for positioning. The controller 6 controls the second lifting device 22 to move the movable frame 15 along the vertical guide rail 13, which lifts the pen-dropping assembly 4 to the set height. Then, the pen 4221 on the cylinder clamping device 422 is controlled to automatically fall from the initial orientation guide tube 423. The pen 4221 is first passed through the initial orientation guide tube 423 to prevent the initial state of swinging and tilting when the cylinder clamping device 422 releases the pen 4221, thus ensuring the pen drop accuracy and realizing the data acquisition of the sample impact force.

[0040] When using the impact force value device 5, the sample to be tested is placed on the test point of the test disk 51, and the impact energy data (weight of the falling ball, self-fall control mode, and falling height) is input into the controller 6. The third laser positioner 521 is used for positioning. The controller 6 controls the second lifting device 22 to move the movable frame 15 along the vertical guide rail 13, driving the second falling ball assembly 52 to rise to the set height. Then, the second ball 5222 on the second ball-attracting electromagnet device 522 is controlled to fall automatically. During the falling process, the second clamping box 532 is opened by the driving cylinder, and the second ball 5222 passes between the two halves of the box 5321. After the second ball 5222 falls on the sample to be tested once, it bounces back. At the same time, the driving cylinder controls the two halves of the box 5321 to close and catch the second ball 5222 that bounced back, avoiding the second ball 5222 from impacting the sample a second time. The force sensor can be used to collect the impact force value of the second ball 5222 to realize the curve of the sample impact force value.

[0041] This invention integrates the ball-dropping device, pen-dropping device, and impact force value device into a compact structure, meeting various testing needs, improving work efficiency, reducing costs, and minimizing floor space and maintenance. The ball-dropping device and impact force value device 5 are equipped with anti-secondary impact components to ensure accurate ball catching and easy handling. The pen-dropping device uses an initial orientation guide tube to prevent initial pen swinging and tilting when the cylinder is released, ensuring pen-dropping accuracy. All three devices—ball-dropping device, pen-dropping device, and impact force value device—use laser positioning devices for alignment, guaranteeing ball-dropping accuracy.
