DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 The utility model provides a technical solution: a swing test bench with an easy-to-replace tabletop, including a base 1. In the field of modern industrial automation, precise control and efficient operation are the ideal states pursued by every engineer. In order to achieve this goal, an advanced test bench system is designed. The system cleverly configures a linear moving device 2 on the base 1, which not only demonstrates excellent technical innovation, but also brings unprecedented convenience and efficiency to industrial production.

[0017] The base 1 is the cornerstone of the entire system, and three carefully arranged linear motion devices 2 are set on it. They are arranged in a circular array with the midpoint of the base 1 as the center. This design not only ensures the stability of the device, but also makes the operation process more flexible and precise. The movement directions of the three linear motion devices 2 all point precisely to the midpoint of the base 1, like three sharp arrows pointing to the bull's eye, ensuring that the system can maintain a high degree of stability and accuracy under any operation.

[0018] The tops of the three linear motion devices 2 are all equipped with first articulated seats 3, which are like joints, connecting the devices with the hydraulic cylinder 4. The hydraulic cylinder 4 is the power source of the entire system, and its telescopic end is closely connected to the magnet 6 through the second articulated seat 5. This design enables the telescopic action of the hydraulic cylinder 4 to be directly converted into the up and down movement of the magnet 6, thereby realizing the precise control of the electromagnet 7.

[0019] The interaction between the magnet 6 and the electromagnet 7 is the core of the whole system. When the magnet 6 rises, it generates magnetic force with the electromagnet 7 under the test bench 8, thereby attracting or repelling the test bench 8. A slot 9 is provided at the lower end of the test bench 8, and the electromagnet 7 is firmly fixed in the slot 9. This design not only ensures the stability of the electromagnet 7, but also provides strong support for its interaction with the magnet 6.

[0020] On the test bench 8, the wire 10 is like a blood vessel, continuously delivering electric current to the electromagnet 7, providing it with strong power support. The electrical connection between the wire 10 and the electromagnet 7 ensures the smooth flow of electric current, and also provides a stable energy guarantee for the entire system.

[0021] This test bench system is not only ingenious in structure design, but also has powerful advantages in function. Its high stability and accuracy enable it to perform excellent performance in various tests and inspections. In addition, the system also uses advanced hydraulic and electromagnetic technologies to make operation simpler and more efficient.

[0022] According to relevant statistics, enterprises that adopt this test bench system have significantly improved product quality inspection and production efficiency. This not only brings considerable economic benefits to enterprises, but also injects new vitality into the development of the entire industrial field.

[0023] Specifically, the linear motion device 2 is an indispensable component of modern industrial machinery. Its precise and stable motion characteristics provide strong support for various automation equipment. The device 2 is mainly composed of three parts: the slide rail 2-1, the slider 2-2 and the support plate 2-3. They each play a vital role and together constitute this efficient and reliable moving system.

[0024] First, the slide rail 2-1 is the foundation of the entire linear motion device. Its design takes into account multiple factors such as high rigidity, high precision and low friction coefficient to ensure that the movement of the slider 2-2 on its track is both smooth and precise. The slide rail 2-1 is usually made of wear-resistant and corrosion-resistant alloy materials, and after precise processing technology, the smoothness and dimensional accuracy of the track surface are ensured. The connection between the slide rail 2-1 and the base 1 adopts a high-strength connection method, such as bolt fixing or welding, to ensure the stability and durability of the entire device.

[0025] The slider 2-2 is a key component in the linear motion device. It carries the support plate 2-3 and other components connected thereto, and moves linearly along the track of the slide rail 2-1. The slider 2-2 is equipped with precision rolling bearings or sliding elements to reduce friction with the slide rail 2-1 and improve movement efficiency. The design of the slider 2-2 takes into account factors such as load capacity, rigidity and precision to ensure stable performance under various working conditions.

[0026] The support plate 2-3 is fixed on the upper side of the slider 2-2, and serves as a platform for connecting and supporting the parts to be moved. The support plate 2-3 is usually made of high-strength, lightweight materials, such as aluminum alloy or composite materials, to reduce the weight of the entire device while maintaining sufficient rigidity and stability. The fixed connection between the support plate 2-3 and the first hinge seat 3 ensures the reliability and accuracy of the connection, so that the entire device can maintain a stable posture and precise trajectory during movement.

[0027] In practical applications, the linear motion device 2 is widely used in various automated equipment, such as CNC machine tools, automated production lines, robots, etc. Its precise and stable motion characteristics provide important support for these devices, enabling them to complete various tasks efficiently and accurately. For example, in CNC machine tools, the linear motion device 2 is responsible for driving the tool or workpiece to perform precise linear motion to achieve high-precision cutting processing; in automated production lines, the linear motion device 2 is responsible for moving the workpiece from one station to another, realizing automation and efficiency of the production process.

[0028] In short, as an important part of modern industrial machinery, the design, manufacture and application of the linear motion device 2 all reflect the high precision, high efficiency and high reliability of the modern machinery manufacturing industry. With the continuous development of industrial automation, the linear motion device 2 will be widely used in more fields and make greater contributions to the development of modern industry.

[0029] Specifically, in precision mechanical design, the combination of a slider and a slide rail is a common structure, which together provide the device with stable and adjustable linear motion. Specifically in our discussion today, the combination of the slider 2-2 and the slide rail 2-1 is a typical example. In order to ensure that the slider 2-2 can slide stably on the slide rail 2-1 and be fixed in a specific position, the designers cleverly designed a device called a slide rail plunger 11.

[0030] The slide rail plunger 11, a seemingly simple part, carries important functions. It cleverly runs through the slider 2-2, one end of which is tightly against the slide rail 2-1, and the other end is connected to the inside of the slider 2-2 through precise threads or other fixing methods. When the slider 2-2 slides on the slide rail 2-1, the slide rail plunger 11 will move with it, but always maintains close contact with the slide rail 2-1, thereby ensuring the stability and accuracy of the slider 2-2 during the sliding process.

[0031] The real value of the slide rail plunger 11 lies in its ability to fix the slider 2-2. When the slider 2-2 needs to stay at a certain position on the slide rail 2-1, the slider 2-2 can be firmly locked at the corresponding position by simply adjusting the slide rail plunger 11 to increase the friction between its inner end and the slide rail 2-1. This design not only improves the stability and reliability of the equipment, but also greatly simplifies the operation process, making the debugging and use of the equipment more convenient.

[0032] In order to better understand the advantages of this design, we can give a practical example. Suppose we are designing a high-precision CNC machine tool, one of the key functions of which is that the tool needs to be able to move accurately on the X-axis and position it to a specified position. In this case, the combination of the slider 2-2 and the slide rail 2-1 and the application of the slide rail plunger 11 are particularly important. By adjusting the slide rail plunger 11, we can ensure that the position accuracy of the tool on the X-axis reaches the micron level, thereby greatly improving the processing accuracy and product quality.

[0033] In addition, the design of the slide rail plunger 11 also fully considers wear resistance and service life. It is made of high-hardness, high-strength materials, can withstand greater pressure and friction, and also has good lubrication properties, which can effectively reduce wear and extend service life. This design not only improves the reliability and stability of the equipment, but also reduces the maintenance cost and downtime of the equipment.

[0034] In summary, the combination of the slider 2-2 and the slide rail 2-1 and the application of the slide rail plunger 11 are an indispensable part of precision mechanical design. Together, they provide the device with a stable, accurate and reliable linear motion function, allowing the device to maintain an efficient and stable operating state in various complex working environments.

[0035] Specifically, an articulated joint 12 is provided between the telescopic end of the hydraulic cylinder 4 and the second articulated seat 5 .

[0036] Specifically, the size and shape of the notch 9 are equal to the size and shape of the electromagnet 7 .

[0037] Working principle: When the utility model is working, the stability and replaceability of the test bench are particularly important. The utility model combines hydraulic technology and electromagnetic adsorption principle to ensure the stability and easy replaceability of the test bench during the swing test.

[0038] First, we introduced a precision hydraulic cylinder as the power source. The hydraulic cylinder 4 is precisely set to provide stable and controllable swing power to ensure that the test bench 8 can swing according to the preset trajectory. The introduction of the hydraulic cylinder not only ensures the stability of the power, but also greatly improves the durability and reliability of the system.

[0039] On the lower side of the test bench 8, we specially designed a notch 9 for fixing the electromagnet 7. The electromagnet 7 is connected to the power supply device through a wire 10. When the power is turned on, the electromagnet 7 will generate a strong magnetic field to firmly adsorb the magnet 6 on the test bench. This design cleverly utilizes the principle of electromagnetic adsorption to ensure that the test bench will not overturn during the swinging process, greatly enhancing the safety of the test.

[0040] The application of electromagnetic adsorption technology not only improves the stability of the test bench, but also greatly simplifies the replacement process of the test bench. When the test bench 8 needs to be replaced, the adsorption relationship between the magnet 6 and the test bench can be easily released by simply turning off the power of the electromagnet 7. This design makes the replacement of the test bench very simple and quick, greatly improving work efficiency.

[0041] It is worth mentioning that our test bench swing system is also highly flexible and scalable. By adjusting the parameters of the hydraulic cylinder, the swing amplitude and frequency of the test bench can be easily changed to meet different test requirements. At the same time, the system can also be seamlessly connected with other equipment to form a complete test solution to meet the test needs of different industries.

[0042] In practical applications, our test bench swing system has achieved remarkable results. For example, a certain auto parts manufacturer used the system to conduct durability tests on auto parts, successfully improving product quality and market competitiveness. At the same time, the system also helped the company achieve rapid replacement and flexible adjustment of the test bench, greatly improving test efficiency and flexibility.

[0043] In summary, the test bench swing system we designed combines hydraulic technology and electromagnetic adsorption principle to achieve stability and easy replacement of the test bench during the swing test. The system is highly flexible and scalable and can meet the testing needs of different industries. In practical applications, the system has achieved remarkable results and made important contributions to the development of scientific experiments and industrial testing.
