Description
Technical Field
[0001] This utility model relates to the field of motor torque measurement technology, specifically a tooling for measuring motor torque. Background Technology
[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. As a power source for electrical appliances or various machines, electric motors need to be tested after they leave the factory. Torque is usually measured using an adjustable platform, lever arm, and crane scale.
[0003] Existing torque measurement fixtures use an adjustable platform, lever arm, and crane scale to measure torque. However, in actual use, different models of motors have different heights, requiring operators to manually elevate the motors at the bottom. Furthermore, slippage can easily occur at the connection point between the two motors, resulting in poor stability and affecting the test results. Therefore, an improved fixture for measuring motor torque is needed to solve these problems. Utility Model Content
[0004] The purpose of this invention is to provide a tooling for measuring motor torque, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for measuring motor torque, comprising a fixed platform and an adjustable platform, wherein a fixed block is fixedly installed on the top of the fixed platform, a test motor is fixedly installed on the top of the fixed block, a fixing mechanism is provided on the right side of the test motor, a fixed frame is slidably installed on the top of the adjustable platform, a sliding frame is slidably installed inside the fixed frame, and an adjustment mechanism is provided on the top of the adjustable platform.
[0006] Preferably, the adjustment mechanism includes a motor, which is fixedly mounted on the front of the fixed frame. A bidirectional threaded rod is fixedly mounted on the output end of the motor. A sliding block is threaded onto the external thread of the bidirectional threaded rod. A connecting rod is rotatably mounted on the top of the sliding block. An electric push rod is fixedly mounted on the top of the sliding frame. A clamping plate is fixedly mounted on the bottom of the electric push rod. The motor under test is disposed inside the sliding frame. A plug-in frame is fixedly mounted on the output end of the motor under test. An electric push rod is fixedly mounted on the top of the fixed platform, so that the plug-in frame and the fixed frame are on the same central axis.
[0007] Preferably, the output end of the electric push rod is fixedly installed with the fixed frame, and the end of the connecting rod away from the sliding block is rotatably installed with the sliding frame, so that the clamping plate clamps the motor under test.
[0008] Preferably, there are two sets of sliding blocks and connecting rods, which are symmetrically distributed around the center line on the right side of the fixed frame. The two sliding blocks are respectively threaded onto the outer sides of the two ends of the bidirectional threaded rod with opposite thread directions to adjust the height of the motor being tested.
[0009] Preferably, the fixing mechanism includes a fixing frame, which is fixedly installed at the output end of the test motor. A spring is fixedly installed inside the fixing frame, and a fixing plate is fixedly installed at the end of the spring away from the fixing frame. A connecting rod is rotatably installed inside the fixing plate, and an arc-shaped plate is rotatably installed at the end of the connecting rod away from the fixing plate. A telescopic rod one is fixedly installed on the top of the arc-shaped plate, and a telescopic rod two is fixedly installed inside the fixing frame. This makes the connection between the test motor and the motor under test more stable and prevents slippage, thereby making the torque measurement more accurate.
[0010] Preferably, the end of the second telescopic rod away from the fixed frame is fixedly installed with the fixed plate, and the end of the first telescopic rod away from the arc plate is fixedly installed with the fixed frame, so that the plug is inserted into the slot of the plug-in frame to limit the operation of the plug-in frame.
[0011] Preferably, the connecting rod, arc plate, plug and telescopic rod are provided in four sets and are circumferentially distributed inside the fixed frame. The plug frame and the plug block are provided with slots at corresponding positions, and the plug block is inserted into the slot to further limit the position of the plug frame.
[0012] Compared with the prior art, this utility model provides a tooling for measuring motor torque, which has the following beneficial effects:
[0013] 1. This fixture for measuring motor torque, through its adjustable mechanism, clamps the motor under test with a clamping plate during use, ensuring that the motor is fixed and restricted, preventing displacement due to vibration, thereby reducing measurement errors. When the motor is started, the motor output drives the bidirectional threaded rod to rotate, which in turn pushes the sliding frame upward, thus aligning the plug-in frame and the fixed frame on the same central axis.
[0014] 2. This fixture for measuring motor torque, through a fixed mechanism, allows the plug to be inserted into the slot of the connector during use, limiting the position of the connector and making the connection between the test motor and the motor under test more stable, preventing slippage and thus making the torque measurement more accurate.

[0023] Example 1:
[0024] Please see Figures 1-2 This utility model provides a technical solution: a tooling for measuring motor torque, including a fixed platform 1 and an adjustable platform 6. A fixed block 4 is fixedly installed on the top of the fixed platform 1, a test motor 5 is fixedly installed on the top of the fixed block 4, a fixing mechanism 3 is provided on the right side of the test motor 5, a fixed frame 7 is slidably installed on the top of the adjustable platform 6, a sliding frame 8 is slidably installed inside the fixed frame 7, and an adjustment mechanism 2 is provided on the top of the adjustable platform 6.
[0025] Furthermore, the adjustment mechanism 2 includes a motor 21, which is fixedly mounted on the front of the fixed frame 7. A bidirectional threaded rod 22 is fixedly mounted on the output end of the motor 21. A sliding block 23 is installed on the external thread of the bidirectional threaded rod 22. A connecting rod 24 is rotatably mounted on the top of the sliding block 23. An electric push rod 25 is fixedly mounted on the top of the sliding frame 8. A clamping plate 26 is fixedly mounted on the bottom of the electric push rod 25. A motor under test 27 is set inside the sliding frame 8. A plug-in frame 28 is fixedly mounted on the output end of the motor under test 27. An electric push rod 29 is fixedly mounted on the top of the fixed platform 1, so that the plug-in frame 28 and the fixed frame 31 are on the same central axis.
[0026] Furthermore, the output end of the electric push rod 29 is fixedly installed with the fixed frame 7, and the end of the connecting rod 24 away from the sliding block 23 is rotatably installed with the sliding frame 8, so that the clamping plate 26 clamps the motor 27 under test.
[0027] Furthermore, two sets of sliding blocks 23 and connecting rods 24 are provided and are symmetrically distributed at the center line on the right side of the fixed frame 7. The two sliding blocks 23 are respectively threaded on the outer ends of the two bidirectional threaded rod 22 with opposite thread directions to adjust the height of the motor 27 under test.
[0028] Example 2:
[0029] Please see Figures 3-4 Furthermore, in conjunction with Embodiment 1, the fixing mechanism 3 includes a fixing frame 31, which is fixedly installed at the output end of the test motor 5. A spring 32 is fixedly installed inside the fixing frame 31. A fixing plate 33 is fixedly installed at the end of the spring 32 away from the fixing frame 31. A connecting rod 34 is rotatably installed inside the fixing plate 33. An arc-shaped plate 35 is rotatably installed at the end of the connecting rod 34 away from the fixing plate 33. A telescopic rod 37 is fixedly installed on the top of the arc-shaped plate 35. A telescopic rod 38 is fixedly installed inside the fixing frame 31. This makes the connection between the test motor 5 and the tested motor 27 more stable and prevents slippage, thereby making the torque measurement more accurate.
[0030] Furthermore, the end of the telescopic rod 38 away from the fixed frame 31 is fixedly installed with the fixed plate 33, and the end of the telescopic rod 37 away from the arc plate 35 is fixedly installed with the fixed frame 31, so that the plug block 36 is inserted into the slot of the plug-in frame 28 to limit the plug-in frame 28.
[0031] Furthermore, four sets of connecting rods 34, arc plate 35, insert block 36 and telescopic rod 37 are provided and are circumferentially distributed inside the fixed frame 31. The plug-in frame 28 has slots at the corresponding positions of the insert block 36, and the insert block 36 is inserted into the slot to further limit the position of the plug-in frame 28.
[0032] In actual operation, when this device is used, the motor 27 to be tested is placed inside the sliding frame 8. The electric push rod 25 is activated, and its output drives the clamping plate 26 to move, thereby clamping the motor 27 and ensuring it is fixed in place. This prevents displacement due to vibration, thus reducing measurement errors. The motor 21 is then activated, and its output drives the bidirectional threaded rod 22 to rotate, causing the connecting rod 24 to push the sliding frame 8 upwards. The plug-in bracket 28 and the fixed frame 31 are on the same central axis. When the electric push rod 29 is activated, the fixed frame 7 is pushed, causing the plug-in bracket 28 to enter the fixed frame 31. The plug-in bracket 28 presses against the fixed plate 33, and the fixed plate 33 presses against the spring 32, which in turn pulls the connecting rod 34. The connecting rod 34 causes the arc plate 35 to move inward, thereby causing the plug block 36 to be inserted into the slot of the plug-in bracket 28. This limits the plug-in bracket 28, making the connection between the test motor 5 and the motor under test 27 more stable and preventing slippage, thus making the torque measurement more accurate.
