[0002] In the process of industrial production and research and development, the reliability of equipment is a key factor to ensure product quality and production efficiency. Vibration is a common phenomenon in the operation of mechanical equipment, and it can be transmitted and reflect the operation state of the equipment in a certain way. By monitoring and analyzing the vibration of mechanical equipment, abnormal conditions inside the equipment, such as bearing damage, gear wear, imbalance, etc., can be detected in time, so as to prevent and solve equipment failures and avoid production interruption and product quality decline.

[0003] Traditional methods for detecting the reliability of equipment highly rely on long-term on-site operation tests. This "trial and error" detection mode has significant limitations. Not only does it take a long time, as the equipment needs to run continuously under specific working conditions to accumulate sufficient data, increasing the uncertainty of the production cycle. Secondly, the cost of on-site testing is high, including the input of human, material and time costs; in addition, on-site testing often fails to comprehensively cover various extreme working conditions and complex environments that the equipment may encounter, resulting in deviation of the detection results and being unable to accurately reflect the true reliability level of the equipment.

[0034] The principles and features of the present utility model will be described below in conjunction with the drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0035] It should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0036] Such as Figure 1 、 Figure 2 And Figure 3As shown in the figure, the device reliability detection device of the present utility model design includes a main frame body 1, on which a deflectable vibration frame 2 is mounted; equipment fixing components 3 are installed at both ends of the vibration frame 2 to ensure that the device under test is stable and does not fall off during vibration; an axle seat 1.1 located on the vibration frame 2 is also provided on the main frame body 1, and a driving main shaft 1.2 is installed in the axle seat 1.1; an eccentric wheel 4 is installed at the output end of the driving main shaft 1.2, and a lever 5 is hinged between the eccentric wheel 4 and the vibration frame 2; a motor driving member 6 connected to the input end of the driving main shaft 1.2 is also installed on the main frame body 1.

[0037] On the main frame body 1, an axle seat 1.1 is specifically provided as the support point of the driving main shaft 1.2. The driving main shaft 1.2 is stably installed through the axle seat 1.1, and an eccentric wheel 4 is installed at its output end. The design of the eccentric wheel 4 makes its center of mass not at the rotation center. Therefore, when the driving main shaft 1.2 is driven to rotate by the motor driving member 6, the eccentric wheel 4 will generate a centrifugal force.

[0038] This centrifugal force is transmitted to the vibration frame 2 through a lever 5 hinged between the eccentric wheel 4 and the vibration frame 2, causing the vibration frame 2 to generate a reciprocating deflection motion. This deflection motion simulates the vibration conditions that mechanical equipment may encounter during actual operation, including different vibration frequencies, amplitudes, and directions.

[0039] During the vibration of the device under test on the vibration frame 2, potential problems inside it (such as bearing damage, gear wear, imbalance, etc.) will be excited and manifested in specific vibration characteristics. By monitoring and analyzing these vibration characteristics, the operating state and reliability of the device under test in a similar vibration environment can be evaluated.

[0040] As an implementation method, the equipment fixing component 3 includes:

[0041] A base 3.1 mounted on the vibration frame 2;

[0042] A moving clamping plate 3.2 and a fixed clamping plate 3.3 oppositely arranged on the base 3.1;

[0043] A sliding groove 3.4 opened on the base 3.1 along the movable direction of the moving clamping plate 3.2;

[0044] A slider 3.5 that is slidably matched with the sliding groove 3.4 and is connected to the moving clamping plate 3.2;

[0045] A threaded seat 3.6 arranged adjacent to the moving clamping plate 3.2;

[0046] A screw 3.7 that is matched with the threaded seat 3.6 and is connected to the moving clamping plate 3.2.

[0047] The base 3.1 serves as the foundation of the entire fixing component and is stably mounted on the vibrating frame 2, providing a solid support platform for the subsequent clamping structure. The movable clamping plate 3.2 and the fixed clamping plate 3.3 are oppositely arranged on the base 3.1 to form a clamping space for clamping the device under test. The sliding groove 3.4 is opened on the base 3.1 along the movable direction of the movable clamping plate 3.2 to provide guidance for the movement of the movable clamping plate. The slider 3.5 is slidably engaged with the sliding groove 3.4 and is connected to the movable clamping plate 3.2, enabling the movable clamping plate to move smoothly along a preset path. By rotating the screw rod, the movable clamping plate can be pushed to move along the sliding groove, thereby adjusting the distance between the movable clamping plate and the fixed clamping plate to clamp devices of different sizes. This threaded adjustment method has self-locking property and can maintain the stability of the clamping force during the vibration process.

[0048] In addition, rubber cushion pads are provided on the opposite sides of the movable clamping plate 3.2 and the fixed clamping plate 3.3, which can not only provide additional buffering during the clamping process to prevent damage to the device under test, but also increase the friction force of the clamping surface and improve the clamping stability.

[0049] As an implementation method, as Figure 3 and Figure 4 shown, a transmission seat 7 is provided at the output end of the driving main shaft 1.2. A rectangular groove 7.1 is opened in the transmission seat 7. A rectangular block 8 connected to the eccentric wheel 4 is provided in the rectangular groove 7.1. Adjusting screws 9 extending into the rectangular groove 7.1 and connected to the rectangular block 8 are arranged around the transmission seat 7.

[0050] Adjusting screws 9 extending into the rectangular groove 7.1 and connected to the rectangular block 8 are arranged around the transmission seat 7. These adjusting screws allow for fine-tuning of the position of the rectangular block 8 in the rectangular groove 7.1 without disassembling the entire transmission device. By rotating the adjusting screws, the relative position between the rectangular block and the transmission seat can be changed, thereby adjusting the relative position or angle between the eccentric wheel and the driving main shaft to adapt to different test requirements or compensate for manufacturing errors.

[0051] Specifically, a limiting portion 10 that partially covers the edge of the rectangular block 8 is formed along the notch of the rectangular groove 7.1 of the transmission seat 7. An opening for connecting the eccentric wheel 4 and the rectangular block 8 is reserved on the limiting portion 10.

[0052] The design of the limiting portion not only enhances the structural strength of the transmission seat but also prevents the rectangular block from disengaging from the rectangular groove during vibration. At the same time, an opening for connecting the eccentric wheel 4 and the rectangular block 8 is reserved on the limiting portion to ensure that the connecting components can pass through and be fixed smoothly.

[0053] As an implementation method, the motor driving member 6 includes:

[0054] A motor 6.1 mounted on the main frame body 1;

[0055] A transmission gearbox 6.2 connected to the output end of the motor 6.1;

[0056] A transmission shaft 6.3 arranged adjacent to the driving main shaft 1.2;

[0057] A first pulley 6.4 provided at the output end of the transmission gearbox 6.2;

[0058] A second pulley 6.5 provided at the input end of the transmission shaft 6.3 and connected to the first pulley 6.4 through a transmission belt;

[0059] A third pulley 6.6 provided at the output end of the transmission shaft 6.3;

[0060] A fourth pulley 6.7 provided at the input end of the driving main shaft 1.2 and connected to the third pulley 6.6 through a transmission belt.

[0061] First, taking the motor 6.1 as a powerful power source, through the precise adjustment of the transmission gearbox 6.2, it ensures a high degree of matching between the output power and the test requirements. Subsequently, a two-stage belt drive system is adopted. The first stage is from the first pulley 6.4 to the second pulley 6.5, and the second stage is from the third pulley 6.6 to the fourth pulley 6.7, ensuring the smooth transmission and conversion of power. It not only realizes the effective distribution of power but also reduces vibration and noise through the characteristics of belt drive. This multi-stage drive design not only improves the flexibility and adaptability of the system but also significantly enhances the stability and reliability of the system.

[0062] It should be noted that in this article, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device. Unless otherwise clearly stipulated and defined, the terms "install", "connect", "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
