Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, specifically to a parallel running-in testing device for multi-specification torque motors with slide rail-roller linkage. Background Technology

[0002] Gear reducers play a crucial role in new energy vehicles, not only improving vehicle power performance but also reducing energy consumption and enhancing driving smoothness. With the continuous development of electric vehicle technology, the design and performance of gear reducers are constantly being optimized to meet the growing market demand. After a gearbox leaves the factory or is repaired, it typically needs to undergo load running-in to eliminate manufacturing errors, ensure uniform tooth surface contact, and test temperature rise, vibration, and sealing performance. Existing running-in test benches generally adopt a "fixed" layout, where the harmonic reducer under test is locked onto a rigid platform using a special fixture, and the drive motor and load device are respectively mounted on fixed supports, with the three connected by a coupling or transition flange. However, this structure has the following drawbacks: existing running-in test devices are time-consuming to change models. When the model of the harmonic reducer under test or the torque motor specification is changed, manual handling increases the labor burden, while using a servo slide or robot increases costs and makes maintenance inconvenient.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0031] The present invention provides the following embodiments.

[0032] Example 1: This embodiment of the invention provides a parallel running-in test device for multi-specification torque motors with slide rail-roller linkage, such as... Figures 1-3 As shown, it includes a slide rail 1, on which several roller slide plates 3 are slidably mounted. The roller slide plates 3 are equipped with the device to be tested. The roller slide plates 3 are connected to several roller fixed plates 4. The roller fixed plates 4 are fixedly connected to the test platform 5. The test platform 5 is connected to the device to be tested.

[0033] Slide rail 1 includes either a linear slide rail or a circular slide rail;

[0034] The number of roller slides 3 is greater than the number of roller fixed plates 4, and the upper front and rear sides of the roller slides 3 and the roller fixed plates 4 are evenly spaced with a number of rollers 6.

[0035] The working principle of the above technical solution is as follows:

[0036] The number of roller plates 4 is the same as the number of test interfaces on the test bench 5. The number of roller slide plates 3 can be adjusted according to the number of devices to be tested. Each roller slide plate 3 is equipped with a device to be tested. The roller slide plate 3 is slidably connected to the slide rail 1, so that the roller slide plate 3 and the devices to be tested on it are arranged in an array. During the test, the roller slide plate 3 connected to the device to be tested is moved to the corresponding position of the roller plate 4. Then the device to be tested is moved along the rollers 6 on the roller slide plate 3 and the roller plate 4 until the device to be tested is connected to the test interface of the test bench 5 and a running-in test is performed. The setting of the rollers 6 and the slide rail 1 makes it much easier to manually push the device to be tested on the plane. There is no need to manually carry the device to be tested, which greatly reduces the burden of manpower. Moreover, the slide rail 1 and the rollers 6 have a simple structure, which reduces the cost and is easy to maintain. It solves the technical problems of the existing running-in test device being time-consuming to change models. When the model of the harmonic reducer or the torque motor specification of the device under test is changed, if the manual carrying method is used, the burden of manpower is increased. If the replacement method of servo slide table or robot is used, the cost is increased and the maintenance is inconvenient.

[0037] The test bench 5 can be equipped with multiple test ports, enabling parallel running tests of devices of the same or different specifications, thus improving testing efficiency. At the same time, the array of devices of different specifications can be arranged on the slide rail 1 by several roller slides 3, eliminating the need for manual handling of the devices and the need to arrange corresponding test stations according to different specifications of the devices, thus saving floor space.

[0038] Example 2: Based on Example 1, such as Figures 1-3 As shown, the device to be tested includes a mounting plate 2. A torque motor 7 and a harmonic reducer 8 are fixedly mounted on the upper end of the mounting plate 2. The torque motor 7 and the harmonic reducer 8 are connected. The lower left and right sides of the mounting plate 2 respectively contact several rollers 6 on the left and right sides.

[0039] Several positioning rods 12 are evenly spaced at the front and rear ends of several roller plates 4, and the positioning rods 12 are positioned between adjacent rollers 6. The positioning rods 12 distributed front and rear correspond one-to-one with the positioning holes at the front and rear ends of the mounting plate 2. The positioning rods 12 are slidably connected to the roller plates 4, and the end of the positioning rod 12 away from the positioning hole is fixedly connected to the connecting plate 10. Several springs 11 are fixedly provided between the connecting plate 10 and the roller plates 4, and the springs 11 are correspondingly sleeved on the positioning rods 12.

[0040] The working principle of the above technical solution is as follows:

[0041] During the break-in test of the equipment under test, the torque motor 7 is started, driving the harmonic reducer 8 to work for testing. The mounting plate 2 can move along the roller 6, thereby driving the torque motor 7 and harmonic reducer 8 mounted on it to move. When the mounting plate 2 moves to the roller fixed plate 4, the connecting plate 10 is pulled to move first. The connecting plate 10 drives the positioning rod 12 to move, and the spring 11 is stretched until the mounting plate 2 drives the torque motor 7 and harmonic reducer 8 mounted on it to the target position. Then the connecting plate 10 is released. Under the elastic action of the spring 11, the connecting plate 10 drives the positioning rod 12 to insert into the positioning hole of the mounting plate 2, so that the mounting plate 2 cannot move along the roller fixed plate 4. This improves the stability of the torque motor 7 when it is working and avoids the mounting plate 2 from shaking when the torque motor 7 is working, which would affect the test results of the harmonic reducer 8.

[0042] Example 3: Based on Example 2, such as Figures 1-5 As shown, the test bench 5 includes a test shell and a load mechanism inside it. The test shell has a test cavity 15 inside, and a cover plate is provided at the upper end of the test cavity 15. The load mechanism is installed in the test cavity 15. Several roller plates 4 are evenly distributed at intervals along the front-back direction on the right end of the test shell. The load mechanism includes several connecting disks 13 provided at the right end of the test shell. The several connecting disks 13 are arranged one-to-one with the several roller plates 4. The right end of the connecting disk 13 is provided with a connecting hole 18, which corresponds to and cooperates with the output block 14 connected to the harmonic reducer 8.

[0043] The working principle of the above technical solution is as follows:

[0044] When the mounting plate 2 is moved to the target position, the output block 14 connected to the harmonic reducer 8 is just in time to mate with the connection hole 18 on the connecting plate 13. The connection hole 18 is equivalent to a test interface. The torque motor 7 is started, which drives the harmonic reducer 8, the connecting plate 13 and the load connected to it to rotate, and the load running-in test is performed. The load on different connecting plates 13 can be adjusted to be compatible with different specifications of torque motor 7 and its connected harmonic reducer 8 with torque of a few Nm to several hundred Nm. This enables parallel running-in tests of the same or different specifications of the test equipment, improving test efficiency.

[0045] Example 4: Based on Example 3, such as Figures 4-8As shown, a sliding groove 39 is fixedly provided on the left end of the connecting plate 13. A sliding block 1 is slidably provided on the sliding groove 39. The sliding block 1 is threadedly connected to the threaded section of the threaded rod 40. The threaded rod 40 is driven by an electrical component installed on the left end of the connecting plate 13. The cylindrical section of the threaded rod 40 passes through the side end of the sliding groove 39 and is fixedly connected to the sensing block 26. The sensing block 26 is correspondingly connected to the sensing switch 48. The left end of the sliding block 1 is fixedly connected to the fixed shaft 38. The fixed shaft 38 is fixedly connected to the fixed plate 17. Three fixing strips 19 are evenly distributed around the side end of the fixed plate 17. The fixing strips 19 distributed on the lower side are fixedly connected to the elastic rod. The elastic rod is fixedly connected to the fixing hole of the fixed plate 17. The fixing strips 19 on the upper side are fixedly connected to the fixed plate 17. The three fixing strips 19 are correspondingly matched with three mating holes. The three mating holes are evenly distributed around the circumference of the limiting plate 20. Several slots 37 are evenly distributed on the fixing strips 19 in the left and right directions.

[0046] A toothed ring 16 is fixedly sleeved on the left side of the connecting plate 13. A gear 31 meshes with the rear side of the toothed ring 16. The gear 31 is fixedly connected to the right side of the rotating shaft 30. The rotating shaft 30 is rotatably set in the test chamber 15. The left side of the rotating shaft 30 is fixedly connected to the centrifugal wheel 21. Several sliding grooves 44 are evenly distributed around the centrifugal wheel 21. A sliding block 42 is slidably set in the sliding groove 44. A spring 43 is fixedly set between the sliding block 42 and the sliding groove 44. The inclined section of the sliding block 42 is in corresponding contact with the inclined section of the push block 32. A spring 33 is fixedly set between the push block 32 and the test chamber 15. The push block 32 is slidably connected to the fixed block 45. The fixed block 45 is fixedly set at the left end of the test chamber 15. The push block 32 is threadedly connected to the threaded section of the operating rod 34. The right end of the operating rod 34 is rotatably connected to the guide ball 35. The guide ball 35 is in corresponding contact with the left end of the limiting plate 20.

[0047] The working principle of the above technical solution is as follows:

[0048] The electrical component installed on the left end of the connecting plate 13 can be a motor. Starting the electrical component can drive the threaded rod 40 to rotate. The threaded rod 40 drives the sliding block 1 to slide along the sliding groove 39. The sliding block 1 drives the fixed shaft 38 to rotate. The fixed shaft 38 drives the fixed plate 17 to move. The fixed plate 17 drives the three fixed bars 19 to move. By changing the position (eccentric position) of the fixed shaft 38 on the connecting plate 13, the center of gravity of the connecting plate 13 and its connected load mechanism is changed, which is equivalent to adjusting the load of the connecting plate 13. When the connecting plate 13 rotates with the output block 14 connected to the harmonic reducer 8, the connecting plate 13 drives the fixed plate 17 to rotate through the sliding block 1 and the fixed shaft 38. The fixed plate 17 drives the limit plate 20 to rotate through the three fixed bars 19.

[0049] A gear ring 16 is fitted onto the connecting plate 13. When the connecting plate 13 rotates with the output block 14 connected to the harmonic reducer 8, it drives the gear ring 16 to rotate. The gear ring 16 drives the gear 31 to rotate. The gear 31 drives the centrifugal wheel 21 to rotate through the rotating shaft 30. The sliding block 42 on the centrifugal wheel 21 moves away from the rotating shaft 30 under centrifugal force. The spring 43 is stretched. After the inclined section of the sliding block 42 contacts the inclined section of the pushing block 32, it can apply a force to the pushing block 32 and make the pushing block 32 move towards the limiting plate 20. The fixed block 45 guides the movement of the pushing block 32. 2. The guide ball 35 is moved towards the limiting plate 20 by the operating lever 34. If the mating hole on the limiting plate 20 cannot move with the guide ball 35 after mating with the fixing bar 19, the setting of the second spring 43 can apply force to the limiting plate 20 through the guide ball 35, so as to limit the limiting plate 20 and prevent the limiting plate 20 from disengaging from the fixing bar 19. The setting of the guide ball 35 ensures that the limiting plate 20 is in contact with the limiting plate 20 when it moves to any position with the fixing plate 17 and when it rotates with the fixing plate 17, and always applies force to the limiting plate 20 to prevent the limiting plate 20 from disengaging from the fixing bar 19 during rotation.

[0050] Example 5: Based on Example 4, such as Figures 4-9 As shown, a number of support plates 22 are evenly distributed along the front-back direction on the lower side of the test chamber 15. A number of placement shells 24 are evenly distributed along the left-right direction on the upper end of the support plates 22. A load plate 25 is placed on the upper end of the placement shell 24. The load plate 25 is correspondingly arranged between three fixing strips 19. A number of openings 1 are evenly distributed along the left-right direction on the lower end of the support plates 22. The openings 1 and 24 are respectively arranged one-to-one. A number of sliders 27 are fixedly provided on the lower end of the support plates 22. The sliders 27 are provided with openings 2, and the openings 2 on the sliders 27 are respectively connected to the openings 1. The lower end of the sliders 27 is fixedly connected to the fixed section of the electric telescopic rod 28. The movable section of the electric telescopic rod 28 is correspondingly engaged with the openings 2. The electric telescopic rod 28 is connected to the induction switch 48 through the controller.

[0051] The working principle of the above technical solution is as follows:

[0052] The three fixing bars 19, the fixing plate 17 and the limiting plate 20 form a placement cage, which is used to place the load plate 25. By placing different numbers of load plates 25 in the placement cage, the center of gravity of the connecting plate 13 and the load mechanism connected thereto can be further adjusted. By changing the number of load plates 25 connected by the fixing bars 19 and the eccentric position of the fixing plate 17 on the connecting plate 13, it can be applied to more specifications of test equipment under the condition of limited number and weight of load plates 25.

[0053] When placing the load tray 25 into the placement cage, the connecting plate 13 is first positioned in its initial position, i.e., the sliding groove 39 is vertically downward. At this time, the sensing block 26 rotates to the position corresponding to the sensing switch 48, and the sensing switch 48 is activated. The sensing block 26 and the sensing switch 48 can use laser sensing, i.e., the sensing switch 48 can be activated when it receives the laser emitted by the sensing block 26. The above sensing method uses existing technology and will not be described in detail in this invention. The sensing block 26 controls the electric telescopic rod 28 to open through the controller. When the target load tray 25 needs to be placed, the electric telescopic rod 28 at the corresponding position of the target load tray 25 is extended. The movable section of the electric telescopic rod 28 is inserted into the slot at the lower end of the placement shell 24 where the load tray 25 is placed, and pushes the placement shell 24 and the load tray 25 upward. Until the load plate 25 contacts the lower fixing strip 19, the load plate 25 is a circular structure. After its arc surface contacts the lower fixing strip 19 distributed front and back, it squeezes the lower fixing strip 19. The lower fixing strip 19 causes the elastic rod to deform until the load plate 25 contacts the upper fixing strip 19. At this time, the center of the load plate 25 and the center of the fixing plate 17 are on the same straight line in the left and right direction. That is, the load plate 25 enters the placement cage. Under the elastic action of the elastic rod, the lower fixing strip 19 returns to its original position. Several slots 37 arranged at intervals in the left and right direction on the fixing strip 19 correspond one-to-one with several placement shells 24 on the support plate 22. That is, the load plate 25 that moves vertically upward can move into the corresponding slot 37 to avoid it from swaying left and right in the placement cage.

[0054] Before placing the load tray 25, the limiting plate 20 must be moved to the left to disengage it from the fixing strip 19. After placement, the limiting plate 20 is moved to the right to engage with the fixing strip 19. At this point, the lower fixing strip 19 cannot move, ensuring the load tray 25 is stably placed in the placement cage. Then, the electric telescopic rod 28 is retracted, and the placement shell 24 moves downwards under gravity. Because the load tray 25 has a large diameter, the lower fixing strip 19 limits its movement, completing the placement of the load tray 25. When removing the load tray 25, the electric telescopic rods 28 corresponding to all load trays 25 in the placement cage are extended, allowing the placement shell 24 to move downwards. Passing through the gap between the front and rear fixed strips 19 on the lower side until the load plate 25 engages with the slot on the placement shell 24, the limiting plate 20 is moved to the left, controlling the electric telescopic rod 28 corresponding to the load plate 25 to be removed to retract. Under the gravity of the load plate 25, the lower fixed strip 19 causes the elastic strip to deform until the load plate 25 is separated from the fixed strip 19. Then, the limiting plate 20 is moved to the right, so that the limiting plate 20 engages with the fixed strip 19. The electric telescopic rods 28 corresponding to all the load plates 25 in the placement cage are retracted again, completing the addition and removal of the target load plate 25. The addition and removal of the load plate 25 do not require manual handling, saving manpower.

[0055] Example 6: Based on Example 4, such as Figures 5-10 As shown, the cylindrical section of the operating rod 34 passes through the left end of the test chamber 15 and is fixedly connected to the external operating disk 36. A suction hole 9 is provided through the inside of the operating rod 34 and the guide ball 35. The guide ball 35 is correspondingly engaged with the sealing hole 41 in the middle of the left end of the limiting disk 20. The suction hole 9 is slidably connected to the sealing rod 29. The sealing rod 29 is fixedly connected to the control disk 46. The control disk 46 is eccentrically provided with a connecting rod 47. The connecting rod 47 is correspondingly engaged with the limiting hole at the left end of the test platform 5, and the connecting rod 47 is slidably connected to the operating disk 36. The connecting rod 47 is fixedly connected to the connecting block. A spring 23 is fixedly provided between the connecting block and the control disk 46, and the spring 23 is sleeved on the connecting rod 47.

[0056] The working principle of the above technical solution is as follows:

[0057] When loading or unloading the load plate 25, the fixed plate 17 should be returned to its original position. Simultaneously with the connection plate 13 being in its initial position, the fixed plate 17 should also be returned to its original position. At this time, the sealing hole 41 on the limiting plate 20 corresponds to the guide ball 35. When controlling the left and right movement of the limiting plate 20, first pull the connecting rod 47, stretching the spring 43. After the connecting rod 47 disengages from the limiting hole at the left end of the test bench 5, the operating plate 36 is rotated via the connecting rod 47. The operating plate 36 then rotates the operating rod 34. Under the limiting action of the pushing block 32 and the spring 33, the operating rod 34 rotates while moving towards the fixing strip 19 until the operating rod 34 causes the guide ball 35 to fit tightly against the sealing hole 41. Then, continue pulling the connecting rod 47. 7. Move away from the operating disc 36. The connecting rod 47 drives the control disc 46 to move through the spring 423. The control disc 46 drives the sealing rod 29 to move. The sealing rod 29 slides along the suction hole 9, which is equivalent to a syringe. This creates a negative pressure between the suction hole 9 and the sealing hole 41, completing the adsorption of the guide ball 35 and the limiting disc 20. Then, control the operating disc 36 to rotate in the opposite direction. The operating disc 36 drives the operating rod 34 to rotate in the opposite direction. The operating rod 34 drives the guide ball 35 and the limiting disc 20 to move away from the fixing strip 19. Since the guide ball 35 is rotatably connected to the operating rod 34 and the limiting disc 20 has gravity, the limiting disc 20 does not rotate with the operating rod 34. The mating hole and the fixing strip 19 remain in correspondence.

[0058] When the limiting plate 20 needs to cooperate with the fixing strip 19, the operating lever 34 is rotated again. The operating lever 34 drives the limiting plate 20 to move closer to the fixing strip 19. After the limiting plate 20 cooperates with the fixing strip 19, the sealing rod 29 is pushed to slide in the opposite direction along the suction hole 9 through the connecting rod 47 and the control plate 46 connected to it, so that the guide ball 35 is no longer attracted to the limiting plate 20. Then, the angle of the operating plate 36 is adjusted so that the connecting rod 47 corresponds to the limiting hole. Then, the connecting rod 47 is released. Under the elastic action of the spring 43, the connecting rod 47 moves towards the operating plate 36 so that the connecting rod 47 cooperates with the limiting hole. This prevents the operating plate 36 from being deflected by external influences and achieves the purpose of driving the limiting plate 20 to move left and right. When adjusting the angle of the operating plate 36, the guide ball 35 will move slightly to the left by a certain distance. The distance that the guide ball 35 moves is less than the cooperation length between the limiting plate 20 and the fixing strip 19, ensuring that the limiting plate 20 is always in a cooperative state with the fixing strip 19.

[0059] During the running-in test, when the push block 32 moves towards the limit plate 20, it can drive the operating rod 34 and its connected operating plate 36 and sealing rod 29 to move towards the limit plate 20. Since the connecting rod 47 cannot move, the sliding connection between the sealing rod 29 and the suction hole 9 ensures the normal movement of the push block 32. When the guide ball 35 disengages from the sealing hole 41, the operating rod 34 drives the push block 32 to move away from the limit plate 20. The spring 33 is compressed. The setting of the spring 33 allows the push block 32 to move left and right while being installed, ensuring that the guide ball 35 is always in contact with different positions of the limit plate 20. Without affecting the limiting effect of the guide ball 35 on the limit plate 20 during the running-in test, the guide ball 35 can also drive the limit plate 20 to move left and right.
