DETAILED DESCRIPTION

[0052] In order to make the purpose, technical scheme and advantages of the present application clearer, further detailed description will be given below in combination with examples and drawings, the illustrative embodiments of the present application and the description thereof are only used to explain the present application, and do not limit the present application.

[0053] As shown in Figure 1 the present application provides a rotary and oscillation integrated life test platform, which comprises a base 1, a rotary drive source 2, a rotary shaft 12, an oscillation shaft 3, a rocker 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 with the base 1; the rotary shaft 12 is in transmission connection with the rotary drive source 2, so that under the driving of the rotary drive source 2, the rotary shaft 12 can rotate around its own axis, and a joint module is assembled on the rotary shaft 12 to realize rotary test; the oscillation shaft 3 is in rotary connection with the base 1, that is, the oscillation shaft 3 can freely rotate around its own axis on the base 1, and a joint module is assembled on the oscillation shaft 3 to realize oscillation test; one end of the rocker 4 is connected with the oscillation shaft 3 for synchronous rotation, so that when the rocker 4 performs oscillation action, the oscillation shaft 3 will be driven to rotate back and forth with small amplitude; the crank connecting rod mechanism is connected between the rocker 4 and the rotary shaft 12 to drive the rocker 4 to oscillate back and forth through the rotation of the rotary shaft 12; the oil dripping mechanism 7 is in transmission connection with the rocker 4 to control the on-off of the oil circuit through the oscillation of the rocker 4, so that the oil dripping frequency of the oil dripping mechanism 7 is controlled through the oscillation frequency of the rocker 4; the oil pushing mechanism 8 is in transmission cooperation with the crank connecting rod mechanism and located in the oil return groove 9, so as to move back and forth in the oil return groove 9 under the driving of the crank connecting rod mechanism, thereby pushing the oil collected in the oil return groove 9 to make the oil return to a specified position, for example, to return to the oil dripping mechanism 7 to form an oil circuit.

[0054] In some optional embodiments, a counterweight 10 is detachably connected to the end of the rocker 4 away from the oscillation shaft 3.

[0055] In the embodiment, the counterweight 10 can increase the load of the swing shaft 3, and by configuring different number and size of the counterweight 10, the load adjustment on the swing shaft 3 can be realized, and more test conditions can be provided.

[0056] In some optional embodiments, referring to Figure 1 and Figure 2 , the oil dripping mechanism 7 comprises an oil storage groove 71, an oil dripping groove 72, an oil blocking plate 73 and a movement assembly; the oil storage groove 71 is used for storing lubricating oil, and the oil storage groove 71 is communicated with the oil return groove 9 through the oil return pipe 11, so that the oil in the oil return groove 9 will enter the oil storage groove 71 through the oil return pipe 11 under the pushing of the oil pushing mechanism 8 to realize the reuse of the lubricating oil; the oil dripping groove 72 is connected with the oil storage groove 71, and the oil dripping groove 72 is provided with an oil passing opening communicated with the oil storage groove 71 and an oil dripping nozzle corresponding to the position of the swing shaft 3, so that the oil dripping nozzle can drip oil to the swing shaft 3; the oil blocking plate 73 is movably arranged in the oil dripping groove 72 and can block the oil passing opening; the movement assembly is movably connected with the base 1 and connected between the rocker 4 and the oil blocking plate 73, so as to drive the oil blocking plate 73 to move back and forth along the direction parallel to the surface of the oil passing opening under the driving of the rocker 4, thereby controlling the opening and closing of the oil passage.

[0057] In actual implementation, the oil dripping groove 72 is a closed hollow structure as a whole, the oil dripping nozzle on the oil dripping groove 72 is a one-way oil dripping nozzle, that is, the external air cannot enter the oil dripping groove 72 through the oil dripping nozzle, and the oil storage groove 71 connected with the oil dripping groove 72 is communicated with the external space; the movement assembly is movably and sealingly matched with the oil dripping groove 72, so as to prevent the air from entering the oil dripping groove 72 when the movement assembly moves relative to the oil dripping groove 72, and ensure the relative sealing of the oil dripping groove 72; wherein, the oil blocking plate 73 blocks or opens the oil passing opening in the direction parallel to the surface of the oil passing opening, and the flow area of the oil at the oil passing opening gradually increases or decreases, which can reduce the oil pressure fluctuation in the oil dripping groove 72, ensure the uniform dripping of the oil dripping nozzle, and the oil blocking plate 73 blocks or opens the oil passing opening in the direction parallel to the surface of the oil passing opening, due to the viscosity of the oil, the edge of the oil blocking plate 73 will form a thin oil film with the edge of the oil passing opening during the movement of the oil blocking plate 73, and the oil film can play an auxiliary sealing role, so that the oil dripping groove 72 and the oil storage groove 71 are more completely isolated, and the space in the oil dripping groove 72 has better sealing performance after the oil passing opening is blocked, so as to prevent the oil dripping nozzle from leaking.

[0058] In some optional embodiments, continuing to refer to Figure 2The motion assembly includes a linear reciprocating assembly 74, an oil blocking rod 75, and an oil blocking transmission rod 76. The fixed part 741 of the linear reciprocating assembly 74 is connected to the base 1. The oil blocking rod 75 is in transmission cooperation with the movable part 742 of the linear reciprocating assembly 74 and is connected to the oil blocking plate 73 so that the oil blocking plate 73 can move in the plane of the oil passing opening. One end of the oil blocking transmission rod 76 is rotationally connected to the rocker 4, and the other end is slidingly connected to the movable part 742 of the linear reciprocating assembly 74. The sliding direction of the oil blocking transmission rod 76 on the movable part 742 is orthogonal to the movement direction of the movable part 742.

[0059] In the embodiments of the present application, it is assumed that in the working state, the oil blocking plate 73 blocks the oil passing opening through up-down movement, that is, the movement direction of the linear reciprocating assembly 74 is vertical. When the rocker 4 swings, the connecting node of the oil blocking transmission rod 76 and the rocker 4 will have a displacement component in the vertical direction, so that the oil blocking transmission rod 76 will drive the movable part 742 to move vertically upward, and the movable part 742 will drive the oil blocking rod 75 to move upward, so that the oil blocking plate 73 moves away from the oil passing opening, and then the oil drip groove body 72 and the oil storage groove body 71 are connected in communication. At this time, the oil drip nozzle drips oil, and the component of the oil blocking transmission rod 76 in the horizontal direction is offset by the relative sliding of the oil blocking transmission rod 76 and the movable part 742.

[0060] In actual implementation, the movable part 742 and the oil blocking rod 75 form intermittent transmission cooperation. For example, the movable part 742 is driven to move to a certain position in the vertical direction and then contacts the oil blocking rod 75. When continuously moving upward, the movable part 742 drives the oil blocking rod 75 to move upward to drive the oil blocking plate 73 to open the oil passing opening. When the movable part 742 moves downward, the oil blocking rod 75 freely falls under the action of its own gravity, so that the oil blocking plate 73 can block the oil passing opening. In this way, intermittent oil supply can be realized, and the oil supply time and the oil supply frequency can also be adjusted by adjusting the initial distance between the oil blocking rod 75 and the movable part 742.

[0061] In some optional embodiments, the end of the oil blocking transmission rod 76 is connected with a first push plate 77 and a second push plate 78. 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 respectively in elastic sliding connection with the movable part 742.

[0062] In the embodiment of the present application, the elastic sliding connection of the first push plate 77 and the second push plate 78 can realize the rapid resetting of the oil blocking transmission rod 76. In actual implementation, in the width direction of the linear reciprocating assembly 74, two baffles are derived on both sides of the movable part 742, and two cylinders are arranged on the two baffles respectively, and two spiral springs are sleeved on the two cylinders respectively. The length of the spiral spring is greater than the length of the cylinder, one end of the two spiral springs is connected with the two baffles respectively, and the other end is connected with the first push plate 77 and the second push plate 78 respectively, that is, in the initial state, the first push plate 77 and the second push plate 78 have a gap with the corresponding cylinder, wherein the sum of the load of the movable part 742, the oil blocking rod 75 and the like is less than the force required for the radial deformation of the spiral spring. In other embodiments, a sliding shaft can also be connected between the two baffles, and the oil blocking transmission rod 76 is connected with the sliding shaft through a sliding bearing.

[0063] In some optional embodiments, referring to Figure 4 , the first push plate 77 and the second push plate 78 are connected through the blocking rod 79, and the blocking rod 79 has a contact plane, wherein the movable part 742 is configured with a ball through a groove locking process which is in contact with the contact plane.

[0064] In the embodiment of the present application, the setting of the ball can provide a guiding effect for the sliding of the blocking rod 79, and in actual implementation, a fish eye bearing 710 can be directly installed on the movable part 742.

[0065] In some optional embodiments, referring to Figure 1 and Figure 3 , the oil pushing mechanism 8 includes a pushing rod 81, a telescopic rod 82 and an oil pushing shovel 83; one end of the pushing rod 81 is located in the oil return groove 9 and is in sliding fit with the base 1; one end of the telescopic rod 82 is movably arranged in the pushing rod 81, that is, the telescopic rod 82 can perform telescopic movement on the pushing rod 81, and the other end is in movable fit with the crank connecting rod mechanism; the oil pushing shovel 83 is located in the oil return groove 9 and is connected with the pushing rod 81.

[0066] 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.

[0067] 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.

[0068] In some optional embodiments, see also 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.

[0069] 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.

[0070] 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.

[0071] In operation, the rotary driving source 2 drives the rotary shaft 12 to rotate, the rotary shaft 12 drives the crank 5 to rotate, the crank 5 rotates relative to the connecting rod 6 and pulls the connecting rod 6, so that the rocker 4 swings; when the rocker 4 swings, the oil blocking transmission rod 76 is lifted synchronously, the movable part 742 is driven by the oil blocking transmission rod 76 to move upward and abut against the oil blocking rod 75, and then the oil blocking rod 75 is driven to move upward to make the oil blocking plate 73 leave the oil passing port, the oil in the oil storage groove body 71 can enter the oil drip groove body 72, and the oil drip nozzle drips oil; after the rocker 4 swings reversely, the movable part 742 finally leaves the oil blocking rod 75, the oil blocking rod 75 is driven by the gravity of the oil blocking rod 75 to block the oil passing port, a closed environment is formed in the oil drip groove body 72, and the oil drip nozzle does not drip oil any more; in the process that the connecting rod 6 is pulled or pushed, the displacement component of the connecting rod 6 in the vertical direction is offset by the extension and retraction of the extension rod 82, so that the extension rod 82 is driven by the connecting rod 6 to generate horizontal displacement, the extension rod 82 synchronously drives the pushing rod 81 to slide on the base 1, and the oil pushing shovel 83 pushes the oil in the oil pushing groove back to the oil storage groove body 71 or makes the oil in the oil collecting groove enter the oil pushing groove at a higher speed.

[0072] The rotary swing integrated service life test platform provided by the embodiment of the application realizes oil circuit circulation by using the oil pushing mechanism 8 and the oil dripping mechanism 7, compared with the oil supply mode by using an oil pump, no large vibration is generated, and the influence on the test result is extremely small; meanwhile, the actions of the oil dripping mechanism 7, the oil pushing mechanism 8 and the swing shaft 3 are all completed by the rotary driving source 2, the actions of the mechanisms are mutually coordinated and synchronously performed, there is no time delay, and the automatic timing control is more reliable than the commonly used automatic timing control; wherein the rotary motion and the swing motion are coupled by the crank connecting rod mechanism, the rotary and swing synchronous service life test is realized; and the oil dripping mechanism 7 and the oil pushing mechanism 8 are directly driven by the crank connecting rod mechanism, the actions of the two are directly related to the rotary shaft 12 and the swing shaft 3, the high coupling of the swing and the oil supply and oil pushing can be realized, so that the oil supply action frequency and the oil pushing action frequency are coordinated with each other, the smooth oil circuit circulation is formed, the swing frequency and the oil supply frequency are coordinated with each other, the swing part can obtain continuous and stable lubrication effect in the whole test process, and the test result has high reliability.
