Description

Technical Field

[0001] This utility model relates to the technical field of motor torque testing platform, specifically to a motor torque testing platform capable of batch testing. Background Technology

[0002] A motor torque testing platform is a device used to test the output torque of a motor. It can measure the torque output of a motor under different loads through different testing methods and conditions, thereby evaluating the performance and quality of the motor. The testing platform is usually composed of a motor, sensors, controllers, data acquisition equipment, etc., and can be customized according to different testing needs. In the fields of motor manufacturing, electric vehicles, aerospace, and robotics, the motor torque testing platform is one of the most important testing devices.

[0003] In existing technologies, motor torque testing platforms need to test a large number of motors. The motors being tested are usually fixed to the platform with bolts, and it is difficult to adjust the fixing of the motors according to their size specifications, resulting in poor applicability. A search revealed that Chinese patent CN220418699U discloses a motor torque testing platform that can be used for batch testing. It can fix motors of different thicknesses by setting a first clamping block, a second clamping block, a first movable rod, and a second movable rod. Furthermore, by setting a movable groove, a movable column, and a fixing nut, it can fix the motor at any position, making it suitable for motors of different lengths. This provides a stable clamping of the motor. However, before fixing the motor, the operator must install the output end of the motor on the right side wall of the coupling. Since the coupling is fixed to the mounting plate at a constant height, when motors of different sizes are placed on the mounting plate, the height of the output end of the motor is not suitable for fitting and mounting on the coupling. The lack of a structure for adjusting the height of the motor has limitations. Utility Model Content

[0004] This invention proposes a motor torque testing platform that can perform batch testing, solving the problems in the prior art of difficulty in adjusting the placement height of motors of different sizes and difficulty in aligning one end of the motor with the coupling.

[0005] The technical solution of this utility model is as follows: A motor torque testing platform capable of batch testing includes a base frame, on which a brake is installed. A sensor and a coupling are installed on one side of the brake. The platform also includes a support frame, a worktable, and an adjustment mechanism. One end of the support frame is fixedly connected to one end of the base frame. The worktable is mounted above the support frame via multiple legs. A through slot that mates with a motor is provided on the worktable. The adjustment mechanism is mounted on the support frame and is used to support and move the motor up and down.

[0006] To ensure that one end of each motor of different sizes can mate with the coupling, the height of the motor can be adjusted. The adjustment mechanism includes a fixed base, a driving bevel gear, a driven bevel gear, a screw, a support plate, a rotating shaft, a rocker arm, and a locking element. The bottom end of the fixed base is fixedly connected to the top end of the support frame. One end of the driving bevel gear is rotatably connected to one end of the fixed base. One end of the driven bevel gear is fixedly connected to the top end of the support frame. The driven bevel gear and the driving bevel gear mesh. One end of the screw passes through the driven bevel gear and the top end of the support frame and extends thereafter. The screw and the driven bevel gear are threaded together and rotatably connected to the support frame. The bottom end of the support plate is rotatably connected to the other end of the screw. One end of the rotating shaft is embedded in the other end of the fixed base and is coaxially fixedly connected to one end of the driving bevel gear. One end of the rocker arm is fixedly connected to the other end of the rotating shaft. The locking element is disposed in the fixed base and is used to fix the rotating shaft.

[0007] To ensure the motor remains stable after height adjustment and prevent height changes, the locking mechanism includes a stop block, two springs, and a locking bolt. The fixed base has a movable groove that mates with the stop block, which is located within the groove. The fixed base contains two contraction cavities. One end of each spring is fixedly connected to the inner bottom wall of one contraction cavity, and the other end is fixedly connected to one end of the stop block. One end of the locking bolt passes through the outer wall of the fixed base and is rotatably connected to one end of the stop block, and is also threadedly connected to the fixed base.

[0008] In order to increase the friction between the abutment block and the rotating shaft and improve the abutment effect, the other end of the abutment block is arc-shaped, and the other end of the abutment block is provided with an anti-slip pad and fits against the outer side wall of the rotating shaft.

[0009] To maintain the stability of the motor, a magnet plate is provided on the support plate for fixing the motor.

[0010] In order to be applicable to motors of different sizes and to avoid collisions between the motor and the inner wall of the through slot when the motor moves up and down, the cross-sectional area of ​​the through slot is larger than the cross-sectional area of ​​the bottom end face of the motor.

[0011] The working principle and beneficial effects of this utility model are as follows:

[0012] In this invention, an adjustment mechanism is provided. Manually rotating the rocker arm drives the rotating shaft to rotate, which in turn drives the motor fixed on the magnet plate to move up and down. When the output end of the motor is aligned with the axis of one end of the coupling, tightening the locking bolt causes it to move toward the rotating shaft, which in turn moves the abutment block and anti-slip pad toward the rotating shaft, thus securing the shaft. This prevents the motor's weight or vibration from causing the screw to rotate and change the motor's height, thereby preventing the rotating shaft from rotating and indirectly maintaining the fixation of the support plate. This allows for the coaxial connection of the output ends of motors of different sizes with one end of the coupling while keeping the coupling height constant, enabling batch testing of motors of different sizes.

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-5As shown, this embodiment proposes a batch testing platform for motor torque, including a base frame 1, a brake 2 on the base frame 1, a sensor 3 and a coupling 4 on one side of the brake 2, one end of the coupling 4 being connected to one end of the motor 22 for testing the torque of the motor 22, and also including a support frame 5, a worktable 6 and an adjustment mechanism, one end of the support frame 5 being fixedly connected to one end of the base frame 1, the worktable 6 being set above the support frame 5 by multiple legs, and a through groove 7 being provided on the worktable 6 to cooperate with the motor 22; in order to be applicable to motors 22 of different sizes and to avoid collision between the motor 22 and the inner wall of the through groove 7 when moving up and down, the cross-sectional area of ​​the through groove 7 is larger than the cross-sectional area of ​​the bottom end face of the motor 22;

[0022] like Figure 1 , such as 3 and Figure 4 As shown, the adjustment mechanism is mounted on the support frame 5 to support and move the motor 22 up and down. To allow motors 22 of different sizes to engage with the coupling at one end, the height of the motor 22 can be adjusted. The adjustment mechanism includes a fixed base 8, a driving bevel gear 9, a driven bevel gear 10, a screw 11, a support plate 12, a rotating shaft 13, a rocker arm 14, and a locking element. The bottom end of the fixed base 8 is fixedly connected to the top end of the support frame 5. One end of the driving bevel gear 9 is rotatably connected to one end of the fixed base 8. One end of the driven bevel gear 10 is fixedly connected to the top end of the support frame 5. The driven bevel gear 10 and the driving bevel gear 9 mesh. One end of the screw 11 passes through the driven bevel gear 10 and the top end of the support frame 5 and extends thereafter. The screw 11 and the driven bevel gear 10 are threadedly connected and rotatably connected to the support frame 5. The bottom end of the support plate 12 is connected to the screw 11. The other end is rotatably connected. In order to maintain the stability of the motor 22, a magnet plate 21 is provided on the support plate 12 to fix the motor 22. One end of the rotating shaft 13 is embedded in the other end of the fixed seat 8 and is coaxially fixedly connected to one end of the active bevel gear 9. One end of the rocker arm 14 is fixedly connected to the other end of the rotating shaft 13. A locking element is provided in the fixed seat 8 to fix the rotating shaft 13. By rotating the rocker arm 14, the rotating shaft 13 is driven to rotate. The rotating shaft 13 drives the active bevel gear 9 to rotate. The active bevel gear 9 drives the driven bevel gear 10 to rotate. The driven bevel gear 10 drives the screw 11 to move vertically up and down. The screw 11 drives the support plate 12 and the magnet plate 21 to move up and down. In this way, the motor 22 fixed on the magnet plate 21 moves up and down. This allows the output end of the motor 22 of different sizes to be coaxially matched with one end of the coupling 4.

[0023] like Figure 2 and Figure 5As shown, in order to keep the motor 22 stable after the height is adjusted and to prevent the height from changing, the locking components include a retaining block 15, two springs 17, and a locking bolt 19. The fixed base 8 has a moving groove 16 that mates with the retaining block 15. The retaining block 15 is placed in the moving groove 16. To increase the friction between the retaining block 15 and the rotating shaft 13 and improve the retaining effect, the other end of the retaining block 15 is arc-shaped. An anti-slip pad 20 is provided on the other end of the retaining block 15 and fits against the outer wall of the rotating shaft 13. Two contraction cavities 18 are provided inside the fixed base 8, and the contraction cavities 18 communicate with the moving groove 16. One end of each spring 17 is fixed to the inner bottom wall of the contraction cavity 18. The other end of the spring 17 is fixedly connected to one end of the abutment block 15. One end of the locking bolt 19 passes through the outer wall of the fixed seat 8 and is rotatably connected to one end of the abutment block 15, and is threadedly connected to the fixed seat 8. The locking bolt 19 is located between the two contraction chambers 18. After adjusting the height position of the motor 22, by tightening the locking bolt 19, the locking bolt 19 moves toward the rotating shaft 13, causing the abutment block 15 and the anti-slip pad 20 to move toward the rotating shaft 13, and pressing the rotating shaft 13 against it. This prevents the screw 11 from rotating due to the weight or vibration of the motor 22, thus preventing the rotating shaft 13 from rotating and indirectly maintaining the fixation of the support plate 12.

[0024] Working Principle: This batch-testable motor torque testing platform is placed in a suitable location. When performing numerous torque tests on motors 22 of different sizes, the platform first places the motor 22 on a magnetic plate 21. Since the motor 22 is generally made of steel, the magnetic attraction of the magnetic plate 21 stabilizes it. The height difference between the output end of the motor 22 and the coupling 4 is observed. By rotating the rocker arm 14, the shaft 13 rotates, driving the motor 22 fixed on the magnetic plate 21 to move up and down. When the output end of the motor 22 is aligned with one end of the shaft of the coupling 4... With the lines aligned, tightening the locking bolt 19 moves the locking bolt 19 toward the rotating shaft 13, causing the abutment block 15 and anti-slip pad 20 to move toward the rotating shaft 13 and press against it. This prevents the screw 11 from rotating due to the weight or vibration of the motor 22, thus changing the height of the motor 22 and preventing the rotating shaft 13 from rotating. This indirectly keeps the support plate 12 fixed. Then, the motor 22 can be moved appropriately to mate the output end of the motor 22 with one end of the coupling 4. This allows the output ends of motors 22 of different sizes to be coaxially mated with one end of the coupling 4. Finally, the torque of the motor 22 is tested in conjunction with the brake 2, sensor 3, etc.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
