Description

Technical Field

[0001] This invention relates to the field of speed reducer testing technology, specifically a speed reducer comprehensive performance testing bench. Background Technology

[0002] The speed reducer is a key component of the power transmission system, and its performance needs to be accurately tested. Currently, common testing benches typically include a fixed drive unit, a loading unit, and a testing station.

[0003] Because the distance between the drive end and the load end is limited, these types of devices are often difficult to adapt to reducers of different lengths, resulting in poor versatility.

[0004] In actual testing, the operation of existing devices is also quite inconvenient. Typically, the reducer needs to be manually moved to the test platform and manually aligned and secured. This method is inefficient, labor-intensive, and the alignment accuracy is difficult to guarantee, easily introducing errors. During testing, the reducer is prone to vibration or displacement due to stress, and traditional clamping methods usually only fix it on one side or in a few positions, failing to achieve uniform and stable full-circumferential constraint, affecting the stability and repeatability of test results.

[0005] In summary, existing speed reducer performance testing devices have the following shortcomings: First, the position adjustment between the drive and load ends is inconvenient, making automated clamping difficult and relying on manual operation, resulting in low efficiency; second, the clamping method is not stable enough, making it difficult to effectively suppress working vibration and affecting the accuracy of the test.

[0006] Therefore, we propose a comprehensive performance testing platform for speed reducers to address the problems mentioned above. Summary of the Invention

[0007] This invention provides a comprehensive performance testing platform for speed reducers, which can solve the problems in the prior art where speed reducer performance testing is not convenient for automated clamping and the clamping method is not stable enough, making it difficult to effectively suppress working vibration and affecting the accuracy of the test.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A speed reducer comprehensive performance testing platform includes a testing platform with a guide groove on its surface. A first sliding seat is slidably disposed at one end of the guide groove, and a second sliding seat is slidably disposed at the other end. A driving mechanism is disposed on the first sliding seat, and a testing mechanism is mounted on the second sliding seat. A first lead screw drive pair for driving the first sliding seat to move is mounted on one side of the guide groove, and a second lead screw drive pair for driving the second sliding seat to move is mounted on the other side of the guide groove. The testing platform has a loading and unloading port in the middle of the guide chute. A conveying and positioning mechanism is provided below the loading and unloading port. The conveying and positioning mechanism includes a conveying component for horizontal conveying of the reducer body and a positioning component for locking the reducer body.

[0009] Preferably, the conveying assembly includes a conveying platform, on which two parallel linear conveying rails are mounted, and a movable disk is mounted on the linear conveying rails. The two linear conveying rails synchronously drive the movable disk to move horizontally.

[0010] Preferably, a positioning block is provided on the upper surface of the movable disk, a conveyor seat is engaged on the upper part of the movable disk, and a positioning groove adapted to the positioning block is opened on the side of the conveyor seat near the movable disk, and the positioning groove and the positioning block are engaged.

[0011] Preferably, the upper surface of the conveyor seat is provided with two locking grooves, and each locking groove is equipped with a set of bidirectional clamping components, which are used to clamp and lock the reducer body placed on the conveyor seat from both sides.

[0012] Preferably, the conveyor table is in contact with the ground, with one end located below the loading and unloading port and the other end extending to the outside of the testing table.

[0013] Preferably, the positioning component includes four sets of electric lifting columns, which are distributed in a matrix below the loading and unloading port and located outside the two linear conveying guide rails; two electric lifting columns on the same side are fixedly connected to an outer protective plate, and the two sets of outer protective plates are symmetrically arranged on both sides of the conveying table.

[0014] Preferably, the outer protective plate is L-shaped, with an inner clamping plate longitudinally arranged on its inner side, and a miniature electric push rod is installed on the outer protective plate to push the inner clamping plate to move horizontally.

[0015] Preferably, the testing platform has guide grooves on both sides of the loading and unloading port perpendicular to the direction of the guide groove, and guide blocks are slidably arranged inside the guide grooves; a lifting drive is fixedly installed at the bottom of the guide groove, and the telescopic end of the lifting drive is fixedly connected to the guide block; an arc-shaped seat is fixedly connected to the upper end of the guide blocks on both sides, and multiple sets of locking elements are evenly distributed in the radial direction of the arc-shaped seat.

[0016] Preferably, the locking component includes a radial drive component, which is fixedly connected to the arc-shaped seat, and its telescopic end faces the inner side of the arc-shaped seat; a locking block is installed on the telescopic end of the radial drive component, which is used to clamp and fix the reducer body externally; an annular pressure sensor is fixedly installed between the locking block and the radial drive component. The locking block has a detection hole inside, which passes through the interior of the annular pressure sensor. A temperature sensor is slidably disposed inside the detection hole. The temperature sensor is rod-shaped and has a limit block on its outer side to prevent it from dislodging from the detection hole. A return spring is installed between one end of the temperature sensor and the detection hole, and the return spring pushes the temperature sensor outward.

[0017] Preferably, the driving mechanism includes a motor base fixedly installed at one end of the outer side of the first sliding seat, a stepper motor fixedly installed on the motor base, and a first speed and torque sensor and a first coupling sequentially installed on the rotating shaft of the stepper motor; The testing mechanism includes a magnetic powder brake installed on the outside of the second sliding seat, a second coupling connected to the inside of the magnetic powder brake, and a second speed and torque sensor installed on the side of the second coupling away from the magnetic powder brake. The reducer body is installed between the first coupling and the second coupling.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are: I. In this invention, the operator only needs to place the reducer body on the conveyor seat. The linear conveyor guide rail in the conveying assembly then drives the moving disc to horizontally deliver the reducer body below the loading / unloading port in the center of the testing platform. Immediately afterwards, the positioning assembly activates, and four sets of electric lifting columns simultaneously raise the L-shaped outer protective plates on both sides, lifting the conveyor seat and reducer as a whole to the testing height. Simultaneously, a miniature electric push rod pushes the inner clamping plate to complete lateral pre-tightening. During this process, the drive mechanism and the testing mechanism, based on the reducer length, adjust the spacing in the guide groove through the independent drives of the first and second lead screw drive pairs. Finally, the first and second couplings precisely align the two ends of the reducer. These automated actions replace traditional manual handling, lifting, and alignment, and maximize the adjustment range of the distance between the drive end and the load end, thus achieving efficient material loading and strong versatility.

[0019] II. In this invention, after the reducer is raised to the working position, the lifting drive component drives the arc-shaped seat to descend, causing it to encircle the reducer housing from above. Subsequently, multiple sets of radial drive components evenly distributed along the circumference of the arc-shaped seat move synchronously, driving each locking block to retract radially towards the center, similar to a "robotic arm" evenly and rigidly clamping the reducer housing from all sides. Through this full-circumferential clamping method, vibration and displacement caused by torque during testing are fundamentally suppressed.

[0020] Meanwhile, the annular pressure sensor integrated between each locking block and the radial drive component can provide real-time feedback on the clamping force at each point, ensuring uniform and controllable force. The temperature sensor, protruding from the return spring inside the locking block, remains in constant contact with the reducer housing, monitoring its operating temperature rise in real time. This combination of robust, full-circumferential locking and real-time monitoring of clamping force and temperature ensures extreme stability during testing, providing a foundation for accurately evaluating the reducer's performance and condition.

[0023] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0024] Example 1: Please see Figure 1-4 The present invention provides a technical solution: A speed reducer comprehensive performance testing platform includes a testing platform 1. A guide groove 2 is formed on the surface of the testing platform 1. A first sliding seat 3 is slidably disposed at one end of the guide groove 2, and a second sliding seat 4 is slidably disposed at the other end. A driving mechanism is disposed on the first sliding seat 3, and a testing mechanism is mounted on the second sliding seat 4. A first lead screw drive pair 11 for driving the first sliding seat 3 to move is mounted on one side of the guide groove 2, and a second lead screw drive pair 12 for driving the second sliding seat 4 to move is mounted on the other side of the guide groove 2. The testing platform 1 is located in the middle of the guide chute 2 and has a loading and unloading port 6. A conveying and positioning mechanism is provided below the loading and unloading port 6. The conveying and positioning mechanism includes a conveying component for horizontal conveying of the reducer body 22 and a positioning component for locking the reducer body 22.

[0025] Through the above scheme, a guide groove 2 is opened on the surface of the testing table 1. The first sliding seat 3 and the second sliding seat 4 can slide along the guide groove 2 and are driven to move by the first lead screw drive pair 11 and the second lead screw drive pair 12 respectively, thereby flexibly adjusting the distance between the drive mechanism and the testing mechanism to accommodate reducer bodies 22 of different lengths. At the same time, the conveying and positioning mechanism below the loading and unloading port 6 automatically conveys the reducer body 22 to the testing position through the conveying component, and then locks it through the positioning component. This scheme solves the problems of inconvenient adjustment of the drive and load end positions, low efficiency caused by reliance on manual handling and alignment in the prior art, realizes automated clamping, and effectively suppresses working vibration through a stable locking method, thereby improving the testing accuracy.

[0026] In some specific implementations, the conveying assembly includes a conveyor platform 5, on which two parallel linear conveying rails 16 are mounted. A movable disk 17 is mounted on each linear conveying rail 16. The two linear conveying rails 16 synchronously drive the movable disk 17 to move horizontally. Through this design, the conveyor platform 5 is flush with the ground, facilitating connection to manual loading stations. The two linear conveying rails 16 on the conveyor platform 5 synchronously drive the movable disk 17 to move horizontally, thereby smoothly conveying the reducer body 22 placed on the movable disk 17 to directly below the loading / unloading port 6 of the inspection table 1. This solves the problems of low efficiency and high labor intensity in manually moving the reducer to the table, achieving automated conveying.

[0027] In some specific embodiments, a positioning block 18 is provided on the upper surface of the movable disk 17, and a conveyor seat 19 is engaged on the upper part of the movable disk 17. A positioning groove adapted to the positioning block 18 is opened on the side of the conveyor seat 19 near the movable disk 17. The positioning groove and the positioning block 18 engage. The positioning block 18 is provided on the upper surface of the movable disk 17, and a matching positioning groove is opened on the bottom of the conveyor seat 19. When the conveyor seat 19 is placed or moved onto the movable disk 17, the positioning block 18 automatically engages with the positioning groove. This design ensures that the position of the conveyor seat 19 on the movable disk 17 is precisely fixed, preventing it from shifting during horizontal conveying and providing a stable foundation for subsequent precise positioning and clamping of the reducer body 22.

[0028] In some specific embodiments, the upper surface of the conveyor seat 19 is provided with two locking grooves 20. Each locking groove 20 is equipped with a set of bidirectional clamping components 21. The bidirectional clamping components 21 are used to clamp and lock the reducer body 22 placed on the conveyor seat 19 from both sides. With the above scheme, the upper surface of the conveyor seat 19 is provided with locking grooves 20, and bidirectional clamping components 21 are installed inside. When the reducer body 22 is placed into the conveyor seat 19, the bidirectional clamping components 21 can move synchronously from both sides, clamping and locking the reducer body 22 under the guidance of the locking grooves 20. By applying external constraints to the reducer body 22 during the conveying stage with two sets of bidirectional clamping components 21, it is prevented from shaking or tipping over during conveying and subsequent lifting, thus improving process stability and safety.

[0029] In some specific implementations, the conveyor platform 5 is flush with the ground, with one end located below the loading / unloading port 6 and the other end extending to the outside of the testing platform 1. The extension of the conveyor platform 5 to the outside of the testing platform 1 facilitates the manual placement of the reducer body 22 on the conveyor seat 19. The fact that the other end of the conveyor platform 5 is located below the loading / unloading port 6 facilitates the movement of the reducer body 22 to the area below the loading / unloading port 6 and its raising to the space between the drive mechanism and the testing mechanism, making it easier to connect and test the reducer body 22.

[0030] Example 2: Please see Figure 1-4 Furthermore, in conjunction with Embodiment 1, it is further found that: 6. The positioning component includes four sets of electric lifting columns 26, which are matrix-distributed below the loading / unloading port 6 and located outside the two linear conveying guide rails 16; two electric lifting columns 26 located on the same side are jointly fixedly connected to an outer protective plate 23, and the two sets of outer protective plates 23 are symmetrically arranged on both sides of the conveying platform 5. The four sets of electric lifting columns 26 are matrix-distributed below the loading / unloading port 6, and they can rise and fall synchronously. Two electric lifting columns 26 located on the same side are jointly connected to an outer protective plate 23. When the moving plate 17 delivers the reducer body 22 to directly below the loading / unloading port 6, the electric lifting columns 26 drive the two sets of outer protective plates 23 to rise, so that they cover and lift the conveying seat 19 and the reducer body 22 from both sides, raising them to the test height, so that the reducer body 22 can be docked with the drive mechanism and the test mechanism.

[0031] In some specific implementations, the outer protective plate 23 is L-shaped, with an inner clamping plate 24 longitudinally arranged on its inner side, and a miniature electric push rod 25 is installed on the outer protective plate 23 to push the inner clamping plate 24 to move horizontally; An inner clamping plate 24 is provided on the inner side of the L-shaped outer protective plate 23, and a miniature electric push rod 25 is installed on the outer protective plate 23. After the electric lifting column 26 is raised to the position, the miniature electric push rods 25 on both sides move synchronously, pushing the inner clamping plate 24 to move horizontally towards the center. The inner clamping plate 24 fits tightly against the outer shell of the reducer body 22 from the side, providing lateral auxiliary positioning and pre-tightening, thus enhancing stability during vertical lifting.

[0032] In some specific implementations, the testing platform 1 has guide grooves 34 on both sides of the loading and unloading port 6 perpendicular to the direction of the guide slide 2, and guide blocks 35 are slidably arranged inside the guide grooves 34; a lifting drive component 36 is fixedly installed at the bottom of the guide grooves 34, and the telescopic end of the lifting drive component 36 is fixedly connected to the guide block 35; an arc-shaped seat 27 is fixedly connected to the upper end of the guide blocks 35 on both sides, and multiple sets of locking components are evenly distributed in the radial direction of the arc-shaped seat 27. The testing platform 1 has guide grooves 34 on both sides of the loading and unloading port 6, in which guide blocks 35 can slide. The lifting drive component 36 at the bottom of the guide groove 34 drives the guide blocks 35 to rise and fall, thereby causing the arc-shaped seat 27 connected to them to rise or fall. After the outer protective plate 23 lifts the reducer body 22 to the testing position, the arc-shaped seat 27 descends under the drive of the lifting drive component 36, and hugs the outer shell of the reducer body 22 from above, thereby circumferentially fixing the reducer body 22 and preventing it from shaking during testing.

[0033] In some specific embodiments, the locking member includes a radial drive member 28, which is fixedly connected to the arc-shaped seat 27, with its telescopic end facing the inner side of the arc-shaped seat 27; a locking block 29 is installed on the telescopic end of the radial drive member 28, which is used to clamp and fix the reducer body 22 externally; an annular pressure sensor 30 is fixedly installed between the locking block 29 and the radial drive member 28; The locking block 29 has a detection hole 31 inside, which passes through the interior of the annular pressure sensor 30. A temperature sensor 32 is slidably disposed inside the detection hole 31. The temperature sensor 32 is rod-shaped and has a limit block on its outer side to prevent it from dislodging from the detection hole 31. A return spring 33 is installed between one end of the inner side of the temperature sensor 32 and the detection hole 31. The return spring 33 pushes the temperature sensor 32 outward.

[0034] Multiple radial drive components 28 on the arc-shaped seat 27 can be driven synchronously or independently, and can be set with equal pressure to drive the locking blocks 29 to move radially toward the center. These locking blocks 29 evenly hug and lock the housing of the reducer body 22 from all sides, achieving a stable full-circumferential rigid lock and effectively suppressing working vibration.

[0035] Both the lifting drive component 36 and the radial drive component 28 are electric telescopic rods.

[0036] The annular pressure sensor 30 monitors and provides feedback on the clamping force of each locking block 29 in real time, ensuring that the clamping force is uniform and controllable. At the same time, the temperature sensor 32 inside the locking block 29 is kept in contact with the surface of the reducer housing by the return spring 33, and its end can be monitored in real time. During locking or testing, the temperature sensor 32 can slide within the detection hole 31 to maintain contact.

[0037] In some specific embodiments, the driving mechanism includes a motor base 7 fixedly installed at one end of the outer side of the first sliding seat 3, a stepper motor 8 fixedly installed on the motor base 7, and a first speed and torque sensor 9 and a first coupling 10 sequentially installed on the rotating shaft of the stepper motor 8; The testing mechanism includes a magnetic powder brake 13 installed on the outside of the second sliding seat 4. A second coupling 15 is connected to the inside of the magnetic powder brake 13. A second speed and torque sensor 14 is installed on the side of the second coupling 15 away from the magnetic powder brake 13. The reducer body 22 is installed between the first coupling 10 and the second coupling 15.

[0038] The stepper motor 8 transmits power to the input shaft of the reducer body 22 via the first coupling 10. The magnetic powder brake 13, as an adjustable load, is connected to the output shaft of the reducer body 22 via the second coupling 15. The first speed and torque sensor 9 and the second speed and torque sensor 14 accurately collect the speed and torque data of the input and output shafts, respectively, thereby calculating the transmission efficiency and other performance parameters of the reducer.

[0039] By driving the first sliding seat 3 and the second sliding seat 4 to move, the distance between the first coupling 10 and the second coupling 15 can be adjusted so that they can be accurately connected to the two ends of the reducer body 22 of different lengths, thus completing the automated connection of the test system.

[0040] The working principle of the comprehensive performance testing platform 1 for the reducer is as follows: First, the reducer body 22, placed on the conveyor seat 19, is automatically conveyed to the area directly below the loading / unloading port 6 via the linear conveyor guide rail 16. Next, the electric lifting column 26 drives the outer protective plate 23 to rise, raising the conveyor seat 19 and the reducer body 22 to the test height. At the same time, the miniature electric push rod 25 pushes the inner clamping plate 24 to pre-tighten the conveyor seat 19 laterally. Subsequently, the lifting drive component 36 drives the arc-shaped seat 27 to descend, so that it surrounds the reducer body 22 from above. Then, multiple sets of radial drive components 28 on the arc-shaped seat 27 act synchronously, driving the locking block 29 to tighten radially, achieving uniform locking of the reducer housing in the entire circumference. At this time, the annular pressure sensor 30 monitors the clamping force, and the temperature sensor 32 detects the housing temperature in real time.

[0041] Finally, the first lead screw drive pair 11 and the second lead screw drive pair 12 adjust the positions of the first sliding seat 3 and the second sliding seat 4 respectively, so that the first coupling 10 and the second coupling 15 are precisely aligned with the two ends of the reducer body 22. Then, the stepper motor 8 and the magnetic powder brake 13 are started to conduct the test, and the performance data is collected by the first speed-torque sensor 9 and the second speed-torque sensor 14. The entire process achieves automatic alignment and secure clamping of the reducer body 22, which is beneficial for automating the rapid alignment testing process.

[0042] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
