[0022] This utility model discloses a motor torque testing device, comprising a mounting base, a drive shaft, a torque wrench, and an adjustment assembly. First, the torque wrench is connected to a flange. Rotating the torque wrench applies a certain torque to the drive shaft. Then, according to the testing requirements of the motor under test, the position of the second friction plate relative to the first friction plate is adjusted using the adjustment assembly.

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0034] like Figures 1 to 4As shown, this utility model embodiment provides a motor torque testing device 100, including a mounting base 1, a drive shaft 2, a torque wrench 3, and an adjustment component 4. The drive shaft 2 is mounted on the mounting base 1 along a first direction X, and the drive shaft 2 is rotatably connected to the mounting base 1. A first friction plate 5 is fixedly connected to the first end of the drive shaft 2, and a flange 6 is fixedly connected to the second end of the drive shaft 2. The torque wrench 3 is detachably connected to the flange 6, and the flange 6 is used to assemble and connect with the motor 200 to be tested after the torque wrench 3 is separated from the flange 6. A guide rod 7 extending along the first direction X is provided on the side of the mounting base 1 away from the flange 6, and a second friction plate 8 is slidably connected to the guide rod 7. The second friction plate 8 abuts against the first friction plate 5. The adjustment component 4 is used to drive the second friction plate 8 to move towards or away from the first friction plate 5 to adjust the friction force between the second friction plate 8 and the first friction plate 5.

[0035] In this embodiment, the motor torque testing device 100 has a first direction X and a second direction Y. The first direction X is the front-back direction when the motor torque testing device 100 is assembled and connected with the motor 200, and the second direction Y is the left-right direction when the motor torque testing device 100 is assembled and connected with the motor 200.

[0036] Mounting base 1 is a supporting component of the motor torque testing device, used to support the drive shaft 2, the adjustment assembly 4, and the motor 200 to be tested. The drive shaft 2 can rotate freely on mounting base 1. The first friction plate 5 is fixedly connected to the first end of the drive shaft 2 and rotates with the drive shaft 2. The second friction plate 8 is slidably connected to mounting base 1 via guide rod 7. The second friction plate 8 can move along guide rod 7 towards or away from the first friction plate 5, thereby adjusting the friction between the second friction plate 8 and the first friction plate 5.

[0037] Flange 6 is fixedly connected to the second end of drive shaft 2. When torque wrench 3 is connected to flange 6, a certain torque can be applied to drive shaft 2 through torque wrench 3. When torque wrench 3 is separated from flange 6, motor 200 to be tested is assembled and connected to flange 6, and motor 200 is started to transmit the output torque of motor 200 to drive shaft 2. In this embodiment, torque wrench 3 is a common torque measuring tool. By applying torque to torque wrench 3, the current torque value can be measured and recorded.

[0038] Based on the above technical solution, in use, first connect the torque wrench 3 to the flange 6, and rotate the torque wrench 3 to apply a certain torque to the drive shaft 2. Then, according to the testing requirements of the motor 200 to be tested, adjust the position of the second friction plate 8 relative to the first friction plate 5 through the adjusting component 4, so that the second friction plate 8 moves closer to or further away from the first friction plate 5, thereby adjusting the friction between the second friction plate 8 and the first friction plate 5, so that the torque applied by the torque wrench 3 reaches the preset torque value. Next, disconnect the torque wrench 3 from the flange 6, assemble and connect the motor 200 to be tested to the flange 6, start the motor 200, and the motor 200 transmits the output torque to the drive shaft 2 through the flange 6, and then to the first friction plate 5, so that the first friction plate 5 rotates, and the motor 200 continues to run under the preset torque value.

[0039] In some embodiments, the torque wrench 3 is rotated, and the second friction plate 8 is adjusted to a first position by the adjusting component 4 to rub against the first friction plate 5 until the torque applied by the torque wrench 3 reaches the first torque value; then the torque wrench 3 is released, and the motor 200 is assembled onto the flange 6 so that the motor 200 runs continuously under the first torque value condition, and the operating data of the motor 200 under the first torque value condition is recorded. The above operation is repeated, adjusting the second friction plate 8 to a second position to rub against the first friction plate 5 until the torque applied by the torque wrench 3 reaches the second torque value, so that the motor 200 runs continuously under the second torque value condition. In this embodiment, the position of the second friction plate 8 is adjusted by the adjusting component 4, thereby adjusting the friction force between the second friction plate 8 and the first friction plate 5, simulating the operating conditions of the motor 200 under different torque loads, thereby evaluating the performance of the motor 200 and realizing the testing of the motor 200 under different torque loads.

[0040] For example, after the torque wrench 3 is connected to the flange 6, the torque wrench 3 is rotated, and the friction between the second friction plate 8 and the first friction plate 5 is adjusted by the adjusting component 4, so that the torque applied by the torque wrench 3 reaches 50 Nm. Then, the torque wrench 3 is disassembled, and the motor 200 to be tested is assembled and connected to the flange 6. The motor 200 is started, and it is run under a torque value of 50 Nm. To adjust the operating condition of the motor 200, the above operation is repeated, and the friction between the second friction plate 8 and the first friction plate 5 is adjusted again, so that the motor 200 runs under a different torque value.

[0041] In one embodiment, such as Figures 3 to 5 As shown, the adjusting component 4 includes an elastic element 41 and a tensioning block 42. One end of the elastic element 41 abuts against the second friction plate 8, and the other end of the elastic element 41 away from the second friction plate 8 abuts against the tensioning block 42.

[0042] Specifically, the elastic element 41 provides elastic force. By abutting against the second friction plate 8, the second friction plate 8 can maintain stable contact with the first friction plate 5. When the first friction plate 5 rotates relative to the second friction plate 8, the two rub against each other, generating a frictional force. In this embodiment, the elastic element 41 can be made of a spring, rubber, or other materials with elastic restoring force.

[0043] Furthermore, the tensioning block 42 abuts against the elastic element 41. By applying an external force to the tensioning block 42, the tensioning block 42 pushes the elastic element 41, causing the elastic element 41 to compress and deform, thereby changing the preload of the elastic element 41 and further adjusting the contact pressure and friction between the second friction plate 8 and the first friction plate 5. It can be understood that when the tensioning block 42 moves closer to the second friction plate 8, the elastic element 41 is compressed and further abuts against the second friction plate 8, increasing the friction between the second friction plate 8 and the first friction plate 5. When the tensioning block 42 moves away from the second friction plate 8, the elastic element 41 is released, reducing the friction between the second friction plate 8 and the first friction plate 5, thereby adjusting the preset torque value.

[0044] The tensioning block 42 can be made of metal, plastic or other sturdy materials, and this embodiment does not impose any specific restrictions.

[0045] In one embodiment, such as Figure 3 and Figure 5 As shown, the second friction plate 8 is provided with a first central hole 81 and a first guide hole 82. The first end of the transmission shaft 2 passes through the first central hole 81, and the guide rod 7 passes through the first guide hole 82. The elastic element 41 includes a spring, which is sleeved on the transmission shaft 2. The two ends of the spring abut against the second friction plate 8 and the tensioning block 42, respectively.

[0046] Specifically, the first central hole 81 is a through hole at the center of the second friction plate 8, the first guide hole 82 is spaced apart from the first central hole 81, the drive shaft 2 passes through the first central hole 81 and the guide rod 7 passes through the first guide hole 82, and the second friction plate 8 can slide on the drive shaft 2 along the first direction X without rotating.

[0047] In use, an external force is applied to the tensioning block 42, which pushes the spring, causing the spring to compress and deform. The spring then abuts against the second friction plate 8, thereby adjusting the friction between the second friction plate 8 and the first friction plate 5. Due to the combined restraining effect of the first central hole 81 and the first guide hole 82, rotation of the second friction plate 8 is prevented; that is, the position of the second friction plate 8 is relatively fixed after adjustment. The rotation of the first friction plate 5 relative to the second friction plate 8 causes the motor 200 to operate at a preset torque value.

[0048] In this embodiment, the spring is sleeved on the transmission shaft 2. During the compression and deformation of the spring, the spring is prevented from deviating from the first direction X, and the spring is prevented from twisting or shifting during the force process, which would cause the preset torque value to change, thus ensuring that the motor 200 continues to run at the preset torque value.

[0049] For example, after the torque wrench 3 is connected to the flange 6, the torque wrench 3 is rotated, and the spring is pushed by the tensioning block 42 to adjust the spring compression, thereby adjusting the friction between the second friction plate 8 and the first friction plate 5, so that the torque applied by the torque wrench 3 reaches 50 Nm, and the motor 200 is replaced so that the motor 200 operates under the condition of a torque value of 50 Nm.

[0050] In one embodiment, such as Figure 3 and Figure 5 As shown, the first center hole 81 is located at the center of the second friction plate 8, and two first guide holes 82 are located on the left and right sides of the first center hole 81 along the second direction Y. The mounting base 1 is provided with two guide rods 7, each guide rod 7 passing through the first guide hole 82, which restricts the second friction plate 8 to slide only along the first direction X on the guide rod 7, preventing the second friction plate 8 from rotating around the transmission shaft 2.

[0051] In one embodiment, such as Figure 3 and Figure 5 As shown, the second friction plate 8 has a first mounting groove 83 on the side facing the spring, and the tensioning block 42 has a second mounting groove 421 on the side facing the spring. The two ends of the spring are respectively embedded in the first mounting groove 83 and the second mounting groove 421.

[0052] Specifically, the first mounting groove 83 is located at the center of the second friction plate 8 and communicates with the first center hole 81. One end of the spring is embedded in the first mounting groove 83 of the second friction plate 8, and the other end of the spring is embedded in the second mounting groove 421 of the tensioning block 42 to prevent the spring from falling off the second friction plate 8 and the tensioning block 42 when pushed or squeezed by the tensioning block 42.

[0053] In one embodiment, such as Figures 3 to 5 As shown, the adjustment assembly 4 also includes a fastener 43; the tensioning block 42 is provided with a second center hole 422 and a second guide hole 423, the first end of the transmission shaft 2 passes through the second center hole 422, and the guide rod 7 passes through the second guide hole 423 and is fastened to the fastener 43.

[0054] Specifically, the guide rod 7 passes through the first guide hole 82 and the second guide hole 423, so that the tensioning block 42 and the second friction plate 8 are slidably connected to the guide rod 7, and the positions of the tensioning block 42 and the second friction plate 8 on the guide rod 7 are adjusted.

[0055] During adjustment, the fastener 43 is tightened or loosened on the guide rod 7, causing the tension block 42 to move closer to or further away from the second friction plate 8. Specifically, when the fastener 43 is further tightened, the tension block 42 moves closer to the second friction plate 8, causing the spring to be further compressed and deformed, and the spring to further abut against the second friction plate 8, increasing the friction between the second friction plate 8 and the first friction plate 5, thereby increasing the preset torque value; when the fastener 43 is loosened, the tension block 42 moves away from the second friction plate 8, releasing the spring, reducing the friction between the second friction plate 8 and the first friction plate 5, thereby reducing the preset torque value.

[0056] In one embodiment, the outer periphery of the guide rod 7 facing the tensioning block 42 is provided with a threaded structure, and the fastener 43 is a nut. The friction between the second friction plate 8 and the first friction plate 5 is adjusted by the threaded engagement between the nut and the threaded structure of the guide rod 7. The operation is simple and convenient.

[0057] In one embodiment, such as Figure 3 As shown, the mounting base 1 is provided with two guide rods 7, the fastener 43 includes two nuts, the second friction plate 8 is provided with two first guide holes 82, the tensioning block 42 is provided with two second guide holes 423, each guide rod 7 is correspondingly inserted into each of the first guide holes 82 and the second guide holes 423, and each nut is correspondingly threaded to each of the guide rods 7, thereby realizing the sliding connection between the second friction plate 8 and the guide rods 7, and adjusting the friction force between the second friction plate 8 and the first friction plate 5 by means of the two nuts.

[0058] In one embodiment, such as Figure 6 As shown, the mounting base 1 has a first mounting hole 11 and a second mounting hole 12 on opposite sides. The first end of the drive shaft 2 passes through the first mounting hole 11 and is fixedly connected to the first friction plate 5. The second end of the drive shaft 2 passes through the second mounting hole 12 and is fixedly connected to the flange 6.

[0059] Specifically, the first end of the drive shaft 2 passes through the first mounting hole 11 and is fixedly connected to the first friction plate 5 by bolts. The second end of the drive shaft 2 passes through the second mounting hole 12 and is fixedly connected to the flange 6 by bolts, welding, or threaded connection. The drive shaft 2 can stably support the first friction plate 5 and the flange 6. When torque is applied to the flange 6 by the torque wrench 3, the drive shaft 2 drives the first friction plate 5 to rotate together, causing friction between the first friction plate 5 and the second friction plate 8. The torque wrench 3 is removed and the motor 200 is assembled and connected to the flange 6. The motor 200 drives the flange 6 to rotate, and the operating condition of the motor 200 under the preset torque value is tested.

[0060] In one embodiment, such as Figure 4 and Figure 6As shown, a bearing 13 is installed in the first mounting hole 11, and the drive shaft 2 passes through the bearing 13 and is rotatably connected to the mounting base 1.

[0061] Specifically, the bearing 13 is fixedly installed in the first mounting hole 11, and the drive shaft 2 is rotatably installed on the bearing 13. The drive shaft 2 is rotatably connected to the mounting base 1 through the bearing 13. The drive shaft 2 rotates smoothly relative to the mounting base 1 under the low friction condition of the bearing 13, which improves the overall performance and accuracy of the motor torque testing device 100.

[0062] In one embodiment, such as Figure 6 As shown, the drive shaft 2 includes a first shaft body 21 and a second shaft body 22 connected to the first shaft body 21. A mounting block 23 is fixed between the first shaft body 21 and the second shaft body 22. The first shaft body 21 extends toward the first friction plate 5, and the first friction plate 5 is fixedly connected to the mounting block 23. The second shaft body 22 extends toward the flange 6 and is fixedly connected to the flange 6.

[0063] Specifically, the first friction plate 5 has multiple first threaded holes spaced around the drive shaft 2, and the mounting block 23 has multiple second threaded holes spaced around the drive shaft 2. Screws are used to pass through the first and second threaded holes (not shown in the attached drawings) to fix the first friction plate 5 and the mounting block 23 together. The first shaft 21, the second shaft 22, and the mounting block 23 can be integrally formed.

[0064] In this embodiment, a spring is sleeved on the first shaft 21, and the first shaft 21 passes through the first center hole 81 of the second friction plate 8, which slides along the first shaft 21. The second shaft 22 is rotatably mounted on the bearing 13, and the flange 6 drives the rotation of the second shaft 22, the mounting block 23, and the first friction plate 5, thereby realizing the rotation of the first friction plate 5 relative to the second friction plate 8, and causing the motor 200 to run at a preset torque value.

[0065] In one embodiment, such as Figure 4 As shown, the motor torque testing device 100 also includes a sleeve adapter 9, which is detachably connected to the flange 6, and the torque wrench 3 is detachably connected to the sleeve adapter 9.

[0066] Specifically, since the connection part of the torque wrench 3 cannot be directly connected and fixed to the flange 6, this embodiment achieves a detachable connection between the flange 6 and the torque wrench 3 by assembling and fixing the sleeve adapter 9 to the flange 6, and then assembling and fixing the torque wrench 3 to the sleeve adapter 9. The sleeve adapter 9 and the flange 6 can be detachably connected by bolts. To accommodate different models of torque wrenches 3, the connection part of the sleeve adapter 9 can be designed with various specifications and sizes to meet different testing requirements.

[0067] In one embodiment, such as Figure 6 As shown, the motor torque testing device 100 also includes a pin 10; the second shaft 22 is provided with a first connecting hole 221, the main shaft 61 of the flange 6 is provided with a second connecting hole 62, the main shaft 61 of the flange 6 is sleeved in the second shaft 22, and the pin 10 is inserted into the first connecting hole 221 and the second connecting hole 62.

[0068] Specifically, the main shaft 61 of the flange 6 is sleeved inside the second shaft 22, and the relative position between the flange 6 and the second shaft 22 is fixed by a pin 10. Further, the pin 10 is inserted into the first connecting hole 221 and the second connecting hole 62, thereby achieving a firm connection between the second shaft 22 and the flange 6, so that the flange 6 is fixedly connected to the drive shaft 2, and the drive shaft 2 can rotate with the flange 6.

[0069] In one embodiment, a locking structure (not shown in the figures) is provided on the pin 10 to prevent the pin 10 from loosening due to vibration or impact during testing. The locking structure may include an elastic locking piece, a threaded locking part, etc., provided on the pin 10. When the pin 10 is inserted into the first connecting hole 221 and the second connecting hole 62, the locking structure can lock the pin 10, thereby ensuring the stability and reliability of the connection between the flange 6 and the drive shaft 2.
