Description

Technical Field

[0001] This invention relates to speed reducer performance testing, specifically a multifunctional speed reducer performance testing workbench. Background Technology

[0002] Currently, speed reducers need to undergo multiple performance tests before leaving the factory, such as noise, idle travel, and running stability. However, most of the existing testing equipment is single-function, which means that different equipment must be used for multiple tests. This not only requires a large investment in equipment and a large floor space, but also requires repeated clamping for each test, making the operation cumbersome and inefficient.

[0003] For example, the Chinese invention patent / utility model patent (application number: CN202010512511.7) discloses a "multi-functional speed reducer performance testing workbench." Its specification states that speed reducers require a series of performance tests before leaving the factory to verify whether their performance meets design requirements. These tests include noise testing, idle travel testing, and stability testing, among others. Because speed reducers require numerous tests, there is currently no comprehensive testing equipment that can perform all performance tests in one machine. Only one performance test can be performed with a single testing device. If multiple tests are needed, different testing devices must be used separately. This not only results in high equipment investment and large space requirements, but also requires repeated clamping for each test, which is very time-consuming and labor-intensive, and the testing and installation process is extremely cumbersome. Traditional testing equipment uses the method of tightening screws on the outer shell of the housing to fix the speed reducer. This fixing method requires repeatedly installing and removing multiple screws, which is very tedious. For speed reducer manufacturers, there are many different models of speed reducers, and a large number of machines need to be tested every day. If they repeatedly disassemble and reassemble the machines and need to replace multiple testing devices, it will consume a lot of manpower and resources, resulting in very low work efficiency and directly affecting the product turnover speed. The aforementioned patent can prove the defects of the existing technology. Therefore, we propose a multi-functional speed reducer performance testing workbench. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional speed reducer performance testing workbench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional speed reducer performance testing workbench, comprising a speed reducer body and a mounting frame bolted to the bottom of the speed reducer body. The bottom of the mounting frame is provided with a snap-fit ​​assembly that reinforces and buffers the speed reducer body by inflating an airbag. The bottom of the snap-fit ​​assembly is provided with a support assembly that can adjust the installation position of the snap-fit ​​assembly by a degree of freedom. The snap-fit ​​assembly includes a top plate arrayed below the mounting frame, and a pad is provided below the top plate. An airbag is pre-set inside the pad.

[0006] Preferably, the top of the pad has an inwardly extending sleeve groove, the pad is sleeved with the airbag through the sleeve groove, and the middle of the top plate has a groove spaced apart.

[0007] Preferably, the bottom edge of the top plate is triangularly spherically fitted with a movable rod, the bottom of the movable rod is spherical, and the side of the pad has a rotating groove corresponding to the movable rod. The rotating groove matches the spherical part at the bottom of the movable rod. The pad is fitted with the movable rod through the rotating groove, and a rubber ring is fitted with the pad through the rotating groove. The rubber ring is located at the top of the rotating groove and is fitted with the movable rod. The rubber ring facilitates sealing of the movable rod while it is connected to the pad.

[0008] Preferably, an extension rod is fixedly installed at the bottom of the movable rod, and the bottom of the extension rod is spherical. The extension rod is spherically connected to an inclined sleeve shaft through the spherical bottom of the extension rod. A telescopic rod extending to the outside of the sleeve shaft is sleeved inside the sleeve shaft. A return spring is fixedly installed at one end of the telescopic rod located on the sleeve shaft, and the telescopic rod is fixedly connected to the inside of the sleeve shaft through the return spring. The other end of the telescopic rod is a ball. The return spring facilitates limiting the movement of the telescopic rod and also facilitates its reset.

[0009] Preferably, a connecting shaft is spherically sleeved on the outer side of the telescopic rod opposite to the return spring, and a mounting plate is provided on the top of the connecting shaft. The mounting plate is in contact with the connecting shaft. A T-shaped connecting rod is fixed on the top of the connecting shaft. A connecting groove corresponding to the connecting rod is opened through the middle of the mounting plate. A torsion spring is sleeved on the outer side of the connecting rod, and the mounting plate is sleeved with the torsion spring through the connecting groove. The connecting rod is connected to the mounting plate through the torsion spring. The torsion spring facilitates limiting the rotation of the connecting shaft when the telescopic rod tilts, and facilitates the reset of the connecting shaft after rotation.

[0010] Preferably, the top rectangular array of the mounting plate has a circular shaft, and the outer side of the circular shaft is equipped with inclined spring clips.

[0011] Preferably, the mounting plate is provided with a limiting plate at intervals above it, and the bottom array of the limiting plate is provided with a bottom groove corresponding to the circular shaft, and the top of the limiting plate is fixedly connected to the bottom of the pad.

[0012] Preferably, the support assembly includes cylinders arranged in an array below the snap-fit ​​assembly, each group of cylinders consisting of two cylinders radially distributed, the output end of each cylinder being rotatably fitted with a snap-fit ​​block, the snap-fit ​​block being Y-shaped.

[0013] Preferably, the cylinder is rotatably sleeved with a second connecting rod via a sleeve block at its top. The second connecting rod is perpendicular to the sleeve block, and a second sleeve block is rotatably sleeved on the outer side of the second connecting rod. The bottom of the second sleeve block is fixedly connected to the bottom of the pad.

[0014] Preferably, a first connecting rod is rotatably sleeved at the bottom of the cylinder, and a first sleeve block is rotatably sleeved on the outer side of the first connecting rod, and a base is fixedly installed at the bottom of the first sleeve block.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention achieves flexible fixation and vibration damping of the reducer through the synergistic effect of airbag inflation and snap-fit ​​components. During vibration testing, the inflated airbag can lift the top plate and wrap around the mounting frame beam, enhancing the fixation effect while absorbing vibration energy. During noise testing, no inflation is required; a spring clip is used to fix the candle, and combined with the principle of acoustic vibration visualization, the noise level is observed by observing the flickering flame, achieving integrated vibration stability and noise detection. The support component uses a cylinder in conjunction with multiple sets of socket blocks and connecting rods, enabling flexible adjustment of the pad and the entire test unit in terms of spatial position and angle. This can simulate the operation of the reducer under different installation states and working conditions, greatly expanding the test coverage. Through a transmission chain composed of a movable rod, extension rod, sleeve shaft, and telescopic rod, the reducer... The minute vibrations during the operation of the speed reducer are transmitted to the mounting plate, causing the round shaft and spring to vibrate and even produce sound. This transforms the vibration state into directly observable mechanical motion and audible signals, improving the intuitiveness of the test and the accuracy of the judgment. The design of the return spring and torsion spring ensures that each moving part automatically resets after testing. The rubber ring seal and the bottom groove of the limiting plate not only prevent the structure from loosening but also limit unnecessary displacement. The overall structure ensures rigidity while having good buffering and self-aligning capabilities, significantly reducing the time spent on repeated clamping and adjustment. This workbench is suitable for the rapid installation and testing of various types of speed reducers. It can complete multiple performance tests with one machine, greatly reducing equipment investment and space occupation. It is particularly suitable for the batch and multi-variety testing needs of production lines, effectively improving testing efficiency and product turnover speed. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 8 As shown, the present invention provides a technical solution: a multi-functional speed reducer performance testing workbench, including a speed reducer body 30 and a mounting frame 29 bolted to the bottom of the speed reducer body 30. The bottom of the mounting frame 29 is provided with a snap-fit ​​component that reinforces and buffers the speed reducer body 30 by inflating an airbag 11. The bottom of the snap-fit ​​component is provided with a support component that can adjust the installation position of the snap-fit ​​component by a degree of freedom. The snap-fit ​​component includes a top plate 9 arrayed below the mounting frame 29, and a pad 8 is provided below the top plate 9. An airbag 11 is preset inside the pad 8.

[0028] In the preferred embodiment of this technical solution, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the top of the pad 8 has an inwardly extending sleeve groove 10, through which the pad 8 is sleeved with the airbag 11. The top plate 9 has a groove 12 spaced apart in the middle. The airbag 11, when inflated, buffers and dampens the reducer body 30. During vibration detection, by continuously inflating the airbag 11, it expands continuously. In its initial inflated state, part of the airbag extends through the groove 12 to the top of the top plate 9, and the slightly inflated airbag wraps around the pre-set crossbeam at the bottom of the mounting frame 29. As the airbag 11 continues to expand, it not only lifts the top plate 9 but also wraps around the crossbeam at the bottom of the mounting frame 29, thus reinforcing the stability of the mounting frame 29. Simultaneously, by lifting the top of the top plate 9 with the inflated airbag 11, it also buffers vibrations generated during the use of the reducer body 30.

[0029] Furthermore, a movable rod 15 is fitted into a triangular spherical shape at the bottom edge of the top plate 9. The bottom of the movable rod 15 is spherical. A rotating groove 13 corresponding to the movable rod 15 is opened through the side of the pad 8. The rotating groove 13 matches the spherical shape at the bottom of the movable rod 15. The pad 8 is fitted with the movable rod 15 through the rotating groove 13. A rubber ring 14 is fitted onto the pad 8 through the rotating groove 13. The rubber ring 14 is located at the top of the rotating groove 13 and is fitted with the movable rod 15. The rubber ring 14 facilitates sealing of the movable rod 15 while it is connected to the pad 8. During vibration testing... As the top plate 9 moves upward under the expansion of the airbag 11, the moving top plate 9 will simultaneously drive the movable rod 15 upward until the ball at the bottom of the movable rod 15 combines with the rotating groove 13. At this time, when the reducer body 30 is in use and generates vibration, the vibration of the reducer body 30 will be transmitted to the top plate 9, and through the top plate 9, the movable rod 15 fixedly installed at its bottom will shake under the limit of the rotating groove 13. Thus, the shaking movable rod 15 shows the actual vibration state of the reducer body 30 in the working state. Furthermore, the airbag 11 in contact with the bottom of the top plate 9 can also buffer the vibration while it is being transmitted.

[0030] Furthermore, an extension rod 16 is fixedly installed at the bottom of the movable rod 15, and the bottom of the extension rod 16 is spherical. The extension rod 16 is spherically connected to an inclined sleeve shaft 17 through the spherical part at the bottom. A telescopic rod 18 extending to the outside of the sleeve shaft 17 is sleeved inside the sleeve shaft 17. A return spring 19 is fixedly installed at one end of the telescopic rod 18 at the sleeve shaft 17, and the telescopic rod 18 is fixedly connected to the inside of the sleeve shaft 17 through the return spring 19. The other end of the telescopic rod 18 is a ball. The return spring 19 is provided to limit the movement of the telescopic rod 18 and to facilitate its reset. During vibration detection, as the extension rod 16 moves upward under the drive of the movable rod 15, the extension rod 16, under the spherical connection at the bottom of the outer side, drives the sleeve shaft 17 to move upward. Under the limit, the return spring 19 inside the sleeve shaft 17 is compressed, thereby changing the inclination of the sleeve shaft 17 and the telescopic rod 18.

[0031] Furthermore, a connecting shaft 22 is spherically sleeved on the outer side of the telescopic rod 18 opposite to the return spring 19, and a mounting plate 20 is provided on the top of the connecting shaft 22. The mounting plate 20 only contacts the connecting shaft 22. A T-shaped connecting rod 23 is fixed to the top of the connecting shaft 22. A connecting groove 21 corresponding to the connecting rod 23 is opened through the middle of the mounting plate 20. A torsion spring 24 is sleeved on the outer side of the connecting rod 23, and the mounting plate 20 is sleeved with the torsion spring 24 through the connecting groove 21. The connecting rod 23 is connected to the mounting plate 20 through the torsion spring 24. The torsion spring 24 facilitates the connection between the telescopic rod 18 and the return spring 19. When the telescopic rod 18 tilts and drives the connecting shaft 22 to rotate, it limits the rotation and facilitates the reset of the connecting shaft 22 after rotation. During vibration detection, as the extension rod 16 moves upward and compresses the reset spring 19, and the sleeve shaft 17 tilts with the telescopic rod 18, it pushes the connecting shaft 22, which is spherically connected to the top of the telescopic rod 18, and the mounting plate 20 on the top of the connecting shaft 22, to move upward. At this time, the vibration generated by the reducer body 30 during operation will be transmitted to the top of the mounting plate 20 through the movable rod 15, the extension rod 16, the sleeve shaft 17, the telescopic rod 18, and the connecting shaft 22.

[0032] Furthermore, the top rectangular array of the mounting plate 20 has a circular shaft 25, and the outer array of the circular shaft 25 is equipped with inclined spring pieces 26. During use, in vibration detection, when vibration is transmitted to the mounting plate 20 and causes the circular shaft 25 and spring pieces 26 in its top array to vibrate, the spring pieces 26 reciprocate under the vibration and strike the mounting plate 20. The vibration and the resulting sound visually demonstrate the degree of vibration of the reducer body 30 during operation, thereby achieving stability detection of the reducer body 30. Simultaneously, the return spring 19 can also, after the detection is completed, return to its original position through its own... The rebound causes the extension rod 16, sleeve shaft 17, and telescopic rod 18 to reset. During noise detection, the airbag 11 is not inflated. At this time, the pad 8 and the top plate 9 are in direct contact. Then, a set of candles can be taken out and fixed by the spring piece 26. At this time, the noise generated by the reducer body 30 can be determined by the principle of sound vibration visualization, using the vibration wave to blow the flame of the candle to sway, and judging the noise level based on the shielding of the flame sway. At this time, the reset spring 19, sleeve shaft 17, and telescopic rod 18 buffer the vibration generated by the reducer body 30 during operation to avoid affecting the use of the candle.

[0033] Furthermore, a limiting plate 27 is provided at intervals above the mounting plate 20, and the bottom array of the limiting plate 27 is provided with a bottom groove 28 corresponding to the round shaft 25. The top of the limiting plate 27 is fixedly connected to the bottom of the pad 8. During vibration detection, when the telescopic rod 18 initially drives the connecting shaft 22 and the mounting plate 20 to rise, it first drives the round shaft 25 to move upward and contact the bottom groove 28 opened at the bottom of the limiting plate 27, thereby limiting the mounting plate 20. At this time, as the telescopic rod 18 continues to tilt, it can also limit the telescopic rod 18 in the opposite way.

[0034] In the preferred embodiment of this technical solution, please refer to Figure 2 and Figure 3 As shown, the support assembly includes cylinders 2 arranged in an array below the snap-fit ​​assembly. Each group of cylinders 2 consists of two cylinders 2 arranged radially. The output end of the cylinder 2 is rotatably fitted with a snap-fit ​​block 5, which is Y-shaped.

[0035] Furthermore, the cylinder 2 is rotatably connected to the second connecting rod 6 via the sleeve block 5 on its top. The second connecting rod 6 is perpendicular to the sleeve block 5. The outer side of the second connecting rod 6 is rotatably connected to the second sleeve block 7, and the bottom of the second sleeve block 7 is fixedly connected to the bottom of the pad plate 8.

[0036] Furthermore, the bottom of the cylinder 2 is rotatably sleeved with a first connecting rod 4, and the outer side of the first connecting rod 4 is rotatably sleeved with a first connecting block 3, and the bottom of the first connecting block 3 is fixedly installed with a base 1. In use, the cylinder 2 arranged in an array and the first connecting block 3, the first connecting rod 4, the second connecting rod 6 and the second connecting block 7 installed at both ends of the cylinder 2 respectively can realize the multi-degree-of-freedom adjustment of the pad 8, thereby changing the installation position and installation angle of the reducer body 30, thus simulating more usage scenarios.
