[0067] Please see Figure 1 , Figure 1 A schematic diagram of the structure of the motor test bench provided by this utility model is shown.

[0068] like Figure 1 As shown, the motor test bench 100 includes a base plate module 10, a first motor positioning module 20, a reduction module 30, a second motor positioning module 40, and a second motor mounting module 50.

[0069] Please see Figures 2 to 4 The base plate module 10 includes a first base plate 11, a connecting shaft 12, and a coupling 13. When installing the motor test bench 100, the first base plate 11 can be placed on the ground, a support component, or any other suitable location or device. A servo motor 14 is mounted and fixed on the first base plate 11. It should be understood that the servo motor 14 can be fixed to the first base plate 11 in any suitable way (e.g., by screw fixing) according to actual needs, and this embodiment of the utility model does not limit this in any way. The input shaft 141 of the servo motor 14 is connected and fixed to the first end of the connecting shaft 12, and the second end of the connecting shaft 12 is connected and fixed to the first end of the coupling 13.

[0070] Please see Figure 1 and Figure 5The first motor positioning module 20 includes a second base plate 21, a positioning plate 22, and a first corner bracket 23. The second base plate 21 is mounted and fixed on the first base plate 11. It should be understood that any suitable method (such as screw fixing) can be used to mount and fix the second base plate 21 to the first base plate 11 according to actual needs, and this embodiment of the utility model does not limit this in any way. The first corner bracket 23 is connected and fixed to the second base plate 21 and the positioning plate 22 respectively. Similarly, any suitable method can be used to connect and fix the first corner bracket 23 to the second base plate 21 and the positioning plate 22 respectively according to actual needs, for example, screw fixing can be used. After the servo motor 14 is mounted and fixed to the first base plate 11, the second base plate 21 is mounted and fixed to the first base plate 11, and the first corner bracket 23 is connected and fixed to the second base plate 21 and the positioning plate 22 respectively, the end face positioning ring 142 of the servo motor 14 is aligned with the positioning plate 22.

[0071] Please see Figure 6 The deceleration module 30 includes a third base plate 31, a first mounting plate 32, and a second bracket 33. The third base plate 31 is mounted and fixed on the first base plate 11. It should be understood that the third base plate 31 can be mounted and fixed on the first base plate 11 in any suitable manner (e.g., by screw fixing) according to actual needs, and this embodiment of the utility model does not limit this in any way. The second bracket 33 is connected and fixed to both the third base plate 31 and the first mounting plate 32. Similarly, the second bracket 33 can be connected and fixed to both the third base plate 31 and the first mounting plate 32 in any suitable manner according to actual needs, for example, by screw fixing.

[0072] Please see Figure 3 , Figure 6 as well as Figure 7a A speed reducer 34 is fixedly mounted on a first mounting plate 32. The first mounting plate 32 has a through hole through which the output shaft 342 of the speed reducer 34 passes. The speed reducer 34 is fixed to the side of the first mounting plate 32 away from the first motor positioning module 20. The output shaft 342 of the speed reducer 34 is connected to the second end of the coupling 13. It is readily understood that the speed reducer 34 can be mounted and fixed to the first mounting plate 32 in any suitable manner (such as by screw fixing) according to actual needs; this embodiment of the invention does not impose any limitations in this regard.

[0073] Please see Figures 6 to 8The second motor positioning module 40 includes a fourth base plate 41, a second mounting plate 42, a triangular plate 43, a flange shaft 44, and a connecting bushing 45. The second mounting plate 42 has a sunflower groove 421 and a first through hole 422. Specifically, the fourth base plate 41 is fixedly mounted on the first base plate 11. It should be understood that the fourth base plate 41 can be fixedly mounted on the first base plate 11 in any suitable way (e.g., by screw fixing) according to actual needs. The triangular plate 43 is connected and fixed to both the fourth base plate 41 and the second mounting plate 42. Similarly, the triangular plate 43 can be connected and fixed to both the fourth base plate 41 and the second mounting plate 42 in any suitable way according to actual needs, such as by screw fixing.

[0074] Please see Figure 9a , Figure 9b and Figure 9c Specifically, the second motor mounting module 50 includes a locking block 51 and a fixing member 52. The locking block 51 has a fan-shaped hole 511. The fixing member 52 passes through the fan-shaped hole 511 and the sunflower groove 421 to install and fix the locking block 51 and the second mounting plate 42, so that the locking block 51 is installed and fixed to the second mounting plate 42. The locking block 51 is fixed to the side of the second mounting plate 42 away from the reduction module 30. It is understood that the fixing member 52 can be any suitable component or device; in this embodiment, the fixing member 52 is a screw. Those skilled in the art can, according to the required installation position, pass the fixing member 52 through the fan-shaped hole 511, and set the locking block 51 and the fixing member 52 in the required position. After passing the fixing member 52 through the corresponding slot in the sunflower groove 421, the fixing member 52 is used to install and fix the locking block 51 and the second mounting plate 42, thereby fixing the locking block 51 to the side of the second mounting plate 42 away from the reduction module 30.

[0075] In this embodiment, the locking block 51 is used to mount and fix the motor under test 53, which is located on the side of the locking block 51 away from the second mounting plate 42. It should be understood that any suitable method (e.g., screw fixing) can be used to mount and fix the motor under test 53 onto the locking block 51 according to actual needs, and this embodiment does not impose any limitations on this. Obviously, in this embodiment, the motor under test 53 is an end-face locking type motor. By using the locking block 51 to fix the end-face locking type motor under test 53 to the second mounting plate 42, the motor under test 53 is fixed, facilitating subsequent testing.

[0076] Please refer to the following: Figure 3 , Figure 6 , Figures 7b to 9cThe flange shaft 44 is connected and fixed to the connecting sleeve 45 and the reducer 34 respectively. The connecting sleeve 45 passes through the first through hole 422 of the second mounting plate 42 and is also connected and fixed to the output shaft of the motor under test 53. It should be understood that any suitable method (such as screw fixing) can be used to connect and fix the flange shaft 44 to the connecting sleeve 45 and the reducer 34 respectively, and to connect and fix the connecting sleeve 45 to the output shaft of the motor under test 53, according to actual needs. This utility model embodiment does not limit this in any way.

[0077] It is worth noting that, please refer to Figure 3 After the input shaft 141 of the servo motor 14 is fixedly connected to the connecting shaft 12, the connecting shaft 12 is fixedly connected to the coupling 13, the coupling 13 is fixedly connected to the output shaft 342 of the reducer 34, the flange shaft 44 is fixedly connected to the connecting sleeve 45 and the reducer 34 respectively, and the connecting sleeve 45 is fixedly connected to the output shaft of the motor under test 53, the input shaft 141, connecting shaft 12, coupling 13, output shaft 342 of the reducer 34, flange shaft 44, connecting sleeve 45 and output shaft of the motor under test 53 are located on the same axis L, that is, all the above components or devices are on the same axis. In this way, the servo motor 14 can be used to perform functional and performance tests on the motor under test 53.

[0078] Understandably, when using a servo motor to test the motor under test, the direction of power output depends on the purpose and method of the test.

[0079] When it is necessary to test parameters such as no-load characteristics and back electromotive force of the motor under test, the servo motor is used as the drive motor. At this time, the servo motor outputs power to the motor under test, and drives the motor under test through the coupling to rotate it to a specific speed, thereby measuring the relevant parameters of the motor under test.

[0080] When it is necessary to test parameters such as the output power and torque characteristics of the motor under test, the servo motor is used as the load motor. In this case, the output power of the motor under test is sent to the servo motor, which drives the servo motor to rotate. The servo motor applies resistance and adjusts the load size through the control system parameters to simulate the actual load conditions, thereby testing the performance and function of the motor under test under different loads.

[0081] In this embodiment of the invention, by creating sunflower-shaped grooves on the second mounting plate of the second motor positioning module, and utilizing the fan-shaped holes of the locking block in the second motor mounting module, various models, specifications, and sizes of motors under test can be freely and flexibly installed onto the test bench for testing without the need to remanufacture or replace the motor mounting module. This approach is suitable for various types of motors under test, improving the versatility of motor testing, reducing testing costs, and the test bench is relatively compact, occupying little space. Furthermore, for the output shafts of various motors under test, only the connecting bushing needs to be replaced to achieve quick and accurate connection, facilitating motor installation and testing, and significantly improving the convenience and efficiency of motor testing.

[0082] Please see Figure 6 In some embodiments of this utility model, the first motor positioning module 20 further includes a first positioning key 24 disposed on the second base plate 21. The first positioning key 24 is fixed to the second base plate 21 and at least partially protrudes from it. During actual assembly, after the positioning plate 22 is embedded in the first positioning key 24 to initially position and connect the second base plate 21 and the positioning plate 22, the first corner bracket 23 is then used to connect and fix it to the second base plate 21 and the positioning plate 22 respectively, making the connection between the second base plate 21 and the positioning plate 22 more stable. It is easily understood that the first positioning key 24 can be a component independent of the second base plate 21. By opening mounting holes in the second base plate 21 that match the shape, size, and height of the first positioning key 24, the first positioning key 24 is fixed in the mounting holes, thereby fixing the first positioning key 24 to the second base plate 21, and at least a portion of the first positioning key 24 protrudes from it.

[0083] Of course, the first positioning key 24 can also be a component integrally formed with the second base plate 21, and the integrally formed first positioning key 24 and second base plate 21 can be directly cast using the corresponding mold.

[0084] In this embodiment, by setting the first positioning key 24 to at least partially protrude from the second base plate 21, the positioning plate 22 is quickly and accurately embedded in the first positioning key 24, thereby enabling the second base plate 21 and the positioning plate 22 to be quickly and accurately connected and fixed.

[0085] Please see Figure 7a In some embodiments, the deceleration module 30 further includes a second positioning key 35 disposed on the third base plate 31. The second positioning key 35 is fixed to the third base plate 31 and at least partially protrudes from the third base plate 31. During actual assembly, the first mounting plate 32 is embedded in the second positioning key 35 to initially position and connect the third base plate 31 and the first mounting plate 32. Then, the second angle bracket 33 is used to connect and fix the third base plate 31 and the first mounting plate 32 respectively, making the connection between the third base plate 31 and the first mounting plate 32 more stable.

[0086] Similarly, the second positioning key 35 can be a component independent of the third base plate 31. This is achieved by creating mounting holes in the third base plate 31 that match the shape, size, and height of the second positioning key 35, and then fixing the second positioning key 35 to these holes. This fixes the second positioning key 35 to the third base plate 31, and the second positioning key 35 at least partially protrudes from the third base plate 31. Alternatively, the second positioning key 35 can also be an integrally formed component with the third base plate 31, and can be directly cast using a suitable mold to obtain an integrally formed second positioning key 35 and third base plate 31.

[0087] In this embodiment, by setting the second positioning key 35 to at least partially protrude from the third base plate 31, the first mounting plate 32 is quickly and accurately embedded in the second positioning key 35, thereby enabling the third base plate 31 and the first mounting plate 32 to be quickly and accurately connected and fixed.

[0088] Please see Figure 8 or Figure 9b In some embodiments, the second motor positioning module 40 further includes a third positioning key 46 disposed on the fourth base plate 41. The third positioning key 46 is fixed to the fourth base plate 41 and at least partially protrudes from it. During actual assembly, the second mounting plate 42 is embedded in the third positioning key 46 to initially position and connect the fourth base plate 41 and the second mounting plate 42. Then, a triangular plate 43 is used to connect and fix the fourth base plate 41 and the second mounting plate 42 respectively, making the connection between the fourth base plate 41 and the second mounting plate 42 more stable.

[0089] Similarly, the third positioning key 46 can be a component independent of the fourth base plate 41. This is achieved by creating mounting holes in the fourth base plate 41 that match the shape, size, and height of the third positioning key 46, and then fixing the third positioning key 46 to these mounting holes. This fixes the third positioning key 46 to the fourth base plate 41, and the third positioning key 46 at least partially protrudes from the fourth base plate 41. Alternatively, the third positioning key 46 can also be an integrally formed component with the fourth base plate 41, and can be directly cast using a suitable mold to obtain an integrally formed third positioning key 46 and fourth base plate 41.

[0090] In this embodiment, by setting the third positioning key 46 to at least partially protrude from the fourth base plate 41, the second mounting plate 42 can be quickly and accurately embedded in the third positioning key 46, thereby enabling the fourth base plate 41 and the second mounting plate 42 to be quickly and accurately connected and fixed.

[0091] Please see Figure 5 as well as Figure 8In some embodiments, the second motor positioning module 40 further includes a sliding component 47 and a fixing component 48. The first base plate 11 has a first groove 111 and a second groove 112, and the extension direction of the first groove 111 and the second groove 112 is the axial direction of the motor shaft of the motor 53 under test or the servo motor 14, that is, it extends along the direction of the axis L.

[0092] The sliding component 47 is disposed in the first groove 111 and slidably connected to the first groove 111. The sliding component 47 is also connected and fixed to the fourth base plate 41. The sliding component 47 can slide relative to the first groove 111, thereby driving the fourth base plate 41 to slide. In this way, the motor under test 53 is adjusted to the required appropriate position, so that the motor under test 53 can be connected and fixed to the reduction motor 34 through the connecting bushing 45 and the flange shaft 44, and then connected to the servo motor 14, and finally the test of the motor under test 53 is completed.

[0093] After adjusting the motor under test 53 to the required position, the fixing component 48 is passed through the fourth base plate 41 and the first base plate 11, and then embedded and fixed in the second groove 112. In this way, the fourth base plate 41 and the first base plate 11 are connected and fixed, thereby fixing the position of the motor under test 53, which is convenient for subsequent testing of the motor under test 53.

[0094] In this embodiment, by setting the sliding component 47 to adjust the position of the motor under test 53, the position of the motor under test with different output shaft lengths can be adjusted along the output shaft direction so that the motor under test 53 is in the required appropriate position. Furthermore, the fixing component 48 is set to fix the motor under test 53 in the required appropriate position, which facilitates the testing of the motor under test 53.

[0095] Please see Figure 5 , Figure 8 and Figure 10 In some embodiments, the sliding assembly 47 includes a slide rail 471 and a slider 472. The slide rail 471 is embedded and fixed in the first groove 111 and at least partially protrudes from the first base plate 11, thereby enabling the slider 472 to be mounted on the slide rail 471. During actual assembly, the slider 472 is slidably embedded in the slide rail 471, and the fourth base plate 41 is connected and fixed to the slider 472. It is easily understood that any suitable method (e.g., screw fixing) can be used to connect and fix the fourth base plate 41 and the slider 472 according to actual needs. The slider 472 can slide relative to the slide rail 471 to drive the fourth base plate 41 to slide, thus adjusting the motor 53 under test to the desired position.

[0096] Please see Figure 8In some embodiments, the fixing component 48 includes a fixing screw 481 and a locking block 482. Specifically, a second through hole 411 is provided on the fourth base plate 41 at a position corresponding to the second groove 112. During actual assembly, the locking block 482 is slidably embedded in the second groove 112, and the fixing screw 481 passes through the second through hole 411 and is connected and fixed to the locking block 482, so that the fourth base plate 41 is connected and fixed to the first base plate 11, thereby fixing the motor 53 under test, which facilitates subsequent related tests on the motor 53 under test.

[0097] Please see Figure 3 and Figure 7b In some embodiments of this utility model, the reducer 34 has a third through hole 341. Specifically, the connecting bushing 45 has a connecting shaft hole 451, and the first end 441 of the flange shaft 44 is embedded in the third through hole 341 of the reducer 34.

[0098] The flange shaft 44 is connected and fixed to the connecting sleeve 45, specifically, the annular end face 442 of the flange shaft 44 is connected and fixed to the first end face of the connecting sleeve 45. It is easy to understand that any suitable method (such as screw fixing) can be used to connect and fix the flange shaft 44 and the connecting sleeve 45 (i.e., the annular end face 442 of the flange shaft 44 and the first end face of the connecting sleeve 45) according to actual needs. The output shaft of the motor under test 53 is embedded and fixed in the connecting shaft hole 451, thereby connecting and fixing the motor under test 53 to the reducer 34 through the flange shaft 44 and the connecting sleeve 45, facilitating subsequent testing of the motor under test 53.

[0099] In this embodiment, the motor under test 53 and the reducer 34 are connected and fixed by using the flange shaft 44 and the connecting bushing 45. In this way, for the output shaft of various motors under test 53, only the connecting bushing 45 needs to be replaced to achieve a quick and accurate connection and fixation between the motor under test 53 and the reducer 34. This facilitates the installation and testing of the motor under test 53 and greatly improves the convenience and efficiency of motor testing.

[0100] It should be understood that when the motor under test is a motor with a built-in gearbox, the gearbox module 30 can be removed, and the flange shaft 44 can be directly connected and fixed to the coupling 13. For example, please refer to [link to relevant documentation]. Figure 9b and Figure 11 The motor under test 53 is a motor with a built-in gearbox. Remove the gearbox module 30 and directly connect and fix the flange shaft 44 to the coupling 13. The installation and fixing methods of the other modules or components are the same as those in the previous embodiment, and will not be described in detail here.

[0101] Please see Figure 12In some embodiments of this utility model, the second motor mounting module 50 further includes a fixing sleeve 54 disposed on the fourth base plate 41, wherein the fixing sleeve 54 is mounted and fixed on the fourth base plate 41. During actual assembly, the motor under test 53 is connected and fixed to the fixing sleeve 54. It is understood that any suitable method (e.g., screw fixing) can be used to connect and fix the motor under test 53 and the fixing sleeve 54 according to actual needs, thereby fixing the motor under test 53 to the fourth base plate 41.

[0102] It is easy to understand that the fixing sleeve 54 can be a component independent of the fourth base plate 41. This is achieved by creating mounting holes in the fourth base plate 41 that match the shape, size, and height of the fixing sleeve 54, and then fixing the fixing sleeve 54 into these mounting holes. This fixes the fixing sleeve 54 to the fourth base plate 41, and the fixing sleeve 54 at least partially protrudes from the fourth base plate 41. Alternatively, the fixing sleeve 54 can be an integrally formed component with the fourth base plate 41, and the integrally formed fixing sleeve 54 and the fourth base plate 41 can be directly cast using a suitable mold.

[0103] In this embodiment, the motor under test 53 is a base-locking type motor. The base-locking type motor under test 53 is fixed to the fourth base plate 41 by using the fixing sleeve 54. In this way, the motor under test 53 is fixed, which facilitates the subsequent testing of the motor under test 53.

[0104] Please see Figure 2 and Figure 6 In some embodiments of this utility model, the base plate module 10 further includes multiple handles 15, which are fixed to the first base plate 11. It is understood that the multiple handles 15 can be fixed to any suitable position on the first base plate 11 in any suitable manner (e.g., by screw fixing) according to actual needs, and this utility model embodiment does not impose any limitations in this regard. Optionally, the base plate module 10 of this utility model embodiment includes four handles 15, and the four handles 15 are respectively fixed to the long edge of the first base plate 11 by screw fixing.

[0105] In this embodiment, by setting and fixing the handle to the first base plate, it is easy to move the entire motor test bench. In this way, the motor under test can be tested in any suitable location, thus improving the flexibility of motor testing.

[0106] In summary, the motor test bench provided by this utility model embodiment, by creating sunflower grooves on the second mounting plate of the second motor positioning module and utilizing the fan-shaped holes of the locking block in the second motor mounting module, allows for the free and flexible installation of various models, specifications, and sizes of motors under test for testing. This eliminates the need to remanufacture or replace the motor mounting module, making it suitable for various types of motors under test, improving the versatility of motor testing, reducing testing costs, and ensuring the test bench is relatively compact and occupies little space. Furthermore, for the output shafts of various motors under test, only the connecting bushing needs to be replaced for quick and accurate connection, facilitating motor installation and testing, and significantly improving the convenience and efficiency of motor testing.
