[0002] A rotary oscillation life test platform is a crucial piece of equipment specifically designed to evaluate the durability and reliability of mechanical components under rotary and oscillating conditions. It can simulate the complex motion patterns experienced by components in real-world working environments, conducting long-term cyclic tests on critical components such as joint bearings, robotic arm joints, and robot joints by precisely controlling parameters such as rotation speed, oscillation angle, and load magnitude. During testing, the platform can monitor key indicators such as component wear, stress distribution, and motion accuracy in real time, providing accurate and scientific data support for product design optimization, quality control, and service life prediction. Widely used in high-end manufacturing sectors such as aerospace, automotive manufacturing, and robotics research and development, it is an indispensable testing tool for ensuring the long-term stable operation of mechanical systems.

[0003] When testing robot joint modules, it is usually necessary to perform rotational tests on the shoulder joint modules and swing tests on the knee and arm joint modules. During the test, the test platform should operate under low vibration conditions as much as possible, and lubricating oil should be supplied in a timely manner to ensure that the load is controllable at least throughout the entire swing life. Existing test platforms usually use timing control, that is, the supply of oil and the swing are independent of each other. The oil supply frequency is not easy to synchronize with the swing frequency, which may lead to problems such as untimely oil supply or oil supply interruption, reducing the reliability of the test results.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0020] like Figure 1 As shown in the figure, this application provides a rotary-oscillating integrated life testing platform, which includes a base 1, a rotary drive source 2, a rotary shaft 12, an oscillating shaft 3, a rocker arm 4, a crank-connecting rod mechanism, an oil dripping mechanism 7, and an oil pushing mechanism 8. The base 1 has an oil return groove 9 for collecting lubricating oil. The rotary drive source 2 is connected to the base 1. The rotary shaft 12 is connected to the rotary drive source 2, so that under the drive of the rotary drive source 2, the rotary shaft 12 can rotate around its own axis. A joint module is mounted on the rotary shaft 12 to realize the rotary test. The oscillating shaft 3 is rotatably connected to the base 1, meaning that the oscillating shaft 3 can freely rotate around its own axis on the base 1. A joint module is mounted on the oscillating shaft 3 to realize the rotary test. Oscillation test; one end of the rocker arm 4 is connected to the swing shaft 3 to rotate synchronously, so that when the rocker arm 4 swings, it will drive the swing shaft 3 to rotate back and forth in a small amplitude; the crank-connecting rod mechanism is connected between the rocker arm 4 and the rotary shaft 12 so that the rocker arm 4 swings back and forth through the rotation of the rotary shaft 12; the oil dripping mechanism 7 is drivenly connected to the rocker arm 4 so as to control the oil circuit opening and closing through the swing of the rocker arm 4, so as to control the oil dripping frequency of the oil dripping mechanism 7 through the swinging frequency of the rocker arm 4; the oil pushing mechanism 8 is drivenly engaged with the crank-connecting rod mechanism and is located in the oil return groove 9 so as to move back and forth in the oil return groove 9 under the drive of the crank-connecting rod mechanism, thereby pushing the oil collected in the oil return groove 9, so that the oil flows back to the designated position, such as flowing back to the oil dripping mechanism 7 to form an oil circuit circulation.

[0021] In some alternative embodiments, a counterweight 10 is detachably connected to one end of the rocker arm 4 away from the swing axis 3.

[0022] In this embodiment, the counterweight 10 can increase the load on the swing shaft 3. By configuring different numbers and sizes of counterweights 10, the load on the swing shaft 3 can be adjusted, which facilitates providing more test conditions.

[0023] In some optional embodiments, reference may also be made to Figure 1 and Figure 2The oil dripping mechanism 7 includes an oil storage tank 71, an oil dripping tank 72, an oil baffle 73, and a motion component. The oil storage tank 71 is used to store lubricating oil. The oil storage tank 71 is connected to the oil return tank 9 through the oil return pipe 11. Under the push of the oil pushing mechanism 8, the oil in the oil return tank 9 will enter the oil storage tank 71 through the oil return pipe 11 to realize the reuse of lubricating oil. The oil dripping tank 72 is connected to the oil storage tank 71. The oil dripping tank 72 is provided with an oil passage that communicates with the oil storage tank 71 and an oil drip nozzle corresponding to the position of the swing shaft 3. Oil can be dripped to the swing shaft 3 through the oil drip nozzle. The oil baffle 73 is movably disposed in the oil dripping tank 72 and can block the oil passage. The motion component is movably connected to the base 1 and connected between the rocker arm 4 and the oil baffle 73. Under the drive of the rocker arm 4, the oil baffle 73 moves back and forth in a direction parallel to the surface where the oil passage is located, thereby controlling the opening and closing of the oil circuit.

[0024] In actual implementation, the oil dripping tank 72 is a completely sealed hollow structure. The oil dripping nozzle on the oil dripping tank 72 is a one-way nozzle, meaning that external air cannot enter the oil dripping tank 72 through the nozzle. The oil storage tank 71 connected to the oil dripping tank 72 is open to the external space. The moving component is in a movable sealing fit with the oil dripping tank 72 to prevent air from entering the oil dripping tank 72 when the moving component moves relative to the oil dripping tank 72, ensuring the relative sealing of the oil dripping tank 72. In this embodiment, the oil baffle 73 blocks or opens the oil passage in a direction parallel to the surface where the oil passage is located. The flow area of ​​the oil at the oil outlet gradually increases or decreases, which reduces the oil pressure fluctuation in the oil dripping tank 72, ensuring that the oil dripping nozzle can drip oil at a uniform speed. Furthermore, the oil baffle 73 blocks or opens the oil outlet in a direction parallel to the surface where the oil outlet is located. Due to the viscosity of the oil, during the movement of the oil baffle 73, its edge will form a thin oil film with the edge of the oil outlet. This oil film will play an auxiliary sealing role, thereby making the oil dripping tank 72 and the oil storage tank 71 more thoroughly isolated. This ensures that after the oil outlet is blocked, the space inside the oil dripping tank 72 has better sealing performance, preventing oil leakage from the oil dripping nozzle.

[0025] In some alternative embodiments, see further. Figure 2 The motion assembly includes a linear reciprocating assembly 74, an oil baffle rod 75, and an oil baffle transmission rod 76; the fixed part 741 of the linear reciprocating assembly 74 is connected to the base 1; the oil baffle rod 75 is in a transmission engagement with the movable part 742 of the linear reciprocating assembly 74 and is connected to the oil baffle plate 73 so that the oil baffle plate 73 can move in the plane where the oil port is located; one end of the oil baffle transmission rod 76 is rotatably connected to the rocker arm 4, and the other end is slidably connected to the movable part 742 of the linear reciprocating assembly 74, wherein the sliding direction of the oil baffle transmission rod 76 on the movable part 742 is orthogonal to the movement direction of the movable part 742.

[0026] In this embodiment, it is assumed that in the working state, the oil baffle 73 blocks the oil passage by moving up and down, which means that the linear reciprocating component 74 moves vertically. When the rocker arm 4 swings, the connection node between the oil baffle transmission rod 76 and the rocker arm 4 will have a displacement component in the vertical direction. As a result, the oil baffle transmission rod 76 will drive the movable part 742 to move vertically upward, and the movable part 742 will drive the oil baffle rod 75 to move upward, thereby causing the oil baffle 73 to leave the oil passage, and then connecting the oil dripping tank 72 and the oil storage tank 71. At this time, the oil dripping nozzle drips oil, and the lateral component of the oil baffle transmission rod 76 is canceled out by the relative sliding between the oil baffle transmission rod 76 and the movable part 742.

[0027] In actual implementation, the movable part 742 and the oil baffle rod 75 form an intermittent contact transmission engagement. For example, after the movable part 742 is driven to a certain vertical position, it will contact the oil baffle rod 75. When it continues to move upward, it will drive the oil baffle rod 75 to move upward, thereby driving the oil baffle plate 73 to open the oil passage. When the movable part 742 moves downward, the oil baffle rod 75 falls freely under its own gravity, thereby enabling the oil baffle plate 73 to block the oil passage. This design can realize intermittent oil supply. By adjusting the initial distance between the oil baffle rod 75 and the movable part 742, the oil supply duration and oil supply frequency can also be adjusted.

[0028] In some optional embodiments, the oil baffle transmission rod 76 is connected to a first push plate 77 and a second push plate 78 at its end. The first push plate 77 and the second push plate 78 are arranged in parallel and spaced apart. The first push plate 77 and the second push plate 78 are elastically slidably connected to the movable part 742, respectively.

[0029] In this embodiment, the elastic sliding connection between the first push plate 77 and the second push plate 78 enables the rapid reset of the oil baffle transmission rod 76. In actual implementation, two baffles extend from both sides of the movable part 742 in the width direction of the linear reciprocating assembly 74. Two cylinders are respectively mounted on the two baffles, and two helical springs are respectively fitted onto the two cylinders. The length of the helical springs is greater than the length of the cylinders. One end of each helical spring is connected to one of the two baffles, and the other end is connected to the first push plate 77 and the second push plate 78. This means that in the initial state, there is a gap between the first push plate 77 and the second push plate 78 and the corresponding cylinders. The sum of the loads on the movable part 742, the oil baffle rod 75, etc., is less than the force required for the radial deformation of the helical springs. In other embodiments, a sliding shaft can be connected between the two baffles, and the oil baffle transmission rod 76 can be connected to the sliding shaft via a sliding bearing.

[0030] In some alternative embodiments, see [reference]. Figure 4 The first push plate 77 and the second push plate 78 are connected by a stop bar 79. The stop bar 79 has a contact plane, wherein the movable part 742 is equipped with balls that contact the contact plane by a grooved ball locking process.

[0031] In this embodiment, the ball bearings provide guidance for the sliding of the stop bar 79. In actual implementation, the fisheye bearing 710 can be directly installed on the movable part 742.

[0032] In some optional embodiments, reference may also be made to Figure 1 and Figure 3 The oil pushing mechanism 8 includes a push rod 81, a telescopic rod 82, and an oil pushing shovel 83; one end of the push rod 81 is located in the oil return groove 9 and is slidably engaged with the base 1; one end of the telescopic rod 82 is movably inserted through the push rod 81, meaning that the telescopic rod 82 can extend and retract on the push rod 81, and the other end is movably engaged with the crank connecting rod mechanism; the oil pushing shovel 83 is located in the oil return groove 9 and is connected to the push rod 81.

[0033] In this embodiment, the vertical displacement of the connection node between the crank connecting rod mechanism and the telescopic rod 82 is canceled by the telescopic movement of the telescopic rod 82, while the horizontal displacement is the stroke of the push rod 81, which means that the push rod 81 will reciprocate in the oil return groove 9 to drive the oil pusher 83 to push oil. In actual implementation, the return oil groove 9 is divided into two parts: the first part is the oil collection groove and the second part is the oil pushing groove. The oil collection groove is an open structure and is located below the swing shaft 3. The oil pushing groove is a relatively sealed structure. The oil pushing groove and the oil collection groove are connected by a one-way valve, which means that the lubricating oil can only flow from the oil collection groove to the oil pushing groove. The oil pushing shovel 83 is located in the oil pushing groove and is movably and sealed to the oil pushing groove. The oil pushing shovel 83 and the oil pushing groove will form a piston structure, so that the return oil groove 9, the oil storage tank body 71, and the push rod 81 form a structure similar to a bellows. For example, when the oil pushing shovel 83 moves to the right, the oil in the oil collection groove will enter the oil pushing groove. When the oil pushing shovel 83 moves to the left, the oil pressure in the oil pushing groove will be squeezed to the return oil pipe 11 and finally reach the oil storage tank body 71.

[0034] In actual implementation, the other end of the telescopic rod 82 is rotatably connected to the connecting rod 6 in the crank-connecting rod mechanism, wherein the telescopic rod 82 and the crank 5 are located on both sides of the connecting rod 6.

[0035] In some optional embodiments, reference may also be made to Figure 5 and Figure 6 The base 1 includes a mounting plate and a base; the mounting plate is an L-shaped plate, and the rotating shaft 12, the swing shaft 3 and the oil dripping mechanism 7 are respectively connected to the mounting plate. A counterweight can be connected to the mounting plate to ensure the stability of the mounting plate; the base has a damping cavity 13, and a number of dampers 14 are installed in the damping cavity 13; wherein, the mounting plate is connected to the dampers 14.

[0036] In this embodiment of the application, the damper 14 can absorb the vibration energy generated during operation, thereby reducing the impact of vibration on the test results.

[0037] In some alternative embodiments, the damper 14 includes a fixed member 141, a movable member 142, and an elastic member 143; the fixed member 141 is connected to a base; the movable member 142 is slidably connected to the fixed member 141 and is also connected to a mounting plate; the elastic member 143 is located between the movable member 142 and the fixed member 141 to enable the movable member 142 to slide elastically.

[0038] During operation, the rotary drive source 2 drives the rotary shaft 12 to rotate, which in turn drives the crank 5 to rotate. The crank 5 rotates relative to the connecting rod 6 and pulls the connecting rod 6, causing the rocker arm 4 to swing. When the rocker arm 4 swings, it simultaneously raises the oil baffle transmission rod 76. The oil baffle transmission rod 76 drives the movable part 742 to move upward and abut against the oil baffle rod 75. Then, it drives the oil baffle rod 75 to move upward so that the oil baffle plate 73 leaves the oil outlet, allowing the oil in the oil storage tank 71 to enter the oil dripping tank 72, while the oil dripping nozzle drips oil. When the rocker arm 4 swings in the opposite direction, the movable part 742 will eventually move away from the oil outlet. When the oil baffle lever 75 is opened, the oil baffle lever 75 will drive the oil baffle plate 73 to block the oil outlet under its own weight, forming a sealed environment in the oil dripping tank 72, and the oil dripping nozzle will no longer drip oil. During the process of the connecting rod 6 being pulled or pushed, the vertical displacement component of the connecting rod 6 will be canceled by the extension and retraction of the telescopic rod 82, so the telescopic rod 82 will be driven by the connecting rod 6 to generate horizontal displacement. The telescopic rod 82 will simultaneously drive the push rod 81 to slide on the base 1, and the oil pusher 83 will push the oil in the oil pusher trough back into the oil storage tank 71, or accelerate the oil in the oil collection tank into the oil pusher trough.

[0039] The rotary-oscillating integrated life testing platform provided in this application embodiment utilizes an oil-pushing mechanism 8 and an oil-drip mechanism 7 to achieve oil circulation. Compared to using an oil pump for oil supply, it does not generate a large amount of vibration, and its impact on the test results is minimal. At the same time, the movements of the oil-drip mechanism 7, the oil-pushing mechanism 8, and the oscillating shaft 3 are all powered by the rotary drive source 2. The movements of each mechanism are coordinated and synchronized, with no time delay, making it more reliable than commonly used automated timing control. Among them, the rotary motion and oscillating motion are coupled through the crank-connecting rod mechanism, realizing synchronous life testing of rotary and oscillating motions. Furthermore, the oil-drip mechanism 7 and the oil-pushing mechanism 8 are directly driven by the crank-connecting rod mechanism, and their movements are directly related to the rotary shaft 12 and the oscillating shaft 3. This enables a high degree of coupling between oscillation and oil supply and pushing, thereby coordinating the oil supply and pushing action frequencies to form a smooth oil circulation. Simultaneously, the oscillation frequency and the oil supply frequency are coordinated, ensuring that the oscillating part can obtain a continuous and stable lubrication effect throughout the test, guaranteeing high reliability of the test results.
