[0003] Existing motor torque testing typically requires the use of torque sensors to measure the motor's torque, such as the motor output torque tester disclosed in patent announcement number CN216246954U. Using torque sensors for testing generally incurs high manufacturing costs and is expensive. Furthermore, torque sensors require regular calibration and maintenance during use, significantly increasing maintenance costs. Additionally, using torque sensors demands specific professional knowledge and operational skills, placing stringent requirements on personnel. Moreover, torque sensors are highly susceptible to environmental factors during testing, such as temperature, humidity, and electromagnetic interference, leading to testing errors and reduced accuracy. Utility Model Content

[0005] Therefore, this utility model provides a stepper motor torque testing mechanism, including a fixed frame, on which a motor is detachably mounted. The output end of the motor is connected to a torque disk and drives the torque disk to rotate. A connecting wire is wound on the torque disk, and a weight is connected to the bottom of the connecting wire. The motor is powered by a power supply device.

[0006] Preferably, the power supply device includes a probe, a mounting plate, and a moving component. The probe is mounted on the mounting plate, the mounting plate is fixedly connected to the moving component, and the moving component drives the probe to insert into the power supply port of the motor.

[0007] Preferably, the moving component includes a cylinder and a connecting rod, one end of the connecting rod being fixedly connected to the mounting plate, and the other end being fixedly connected to the piston rod of the cylinder.

[0008] Preferably, the mounting plate has a groove, which provides mounting space for the probe.

[0009] Preferably, the fixing frame includes a main frame, a positioning plate, a fixing plate, and a main support plate. The positioning plate, the fixing plate, and the main support plate are sequentially fixedly installed on the main frame. The motor is detachably installed on the fixing plate. The torque disk is rotatably installed on the main support plate. The connecting rod passes through the positioning plate and the main support plate in sequence and is connected to the piston rod of the cylinder.

[0010] Preferably, the output end of the motor has a flat structure, and the center of the torque disk has a socket that matches the output end.

[0011] Preferably, a rotating rod is fixedly installed on the torque disk, the rotating rod is rotatably connected to the main support plate through a bearing, and a limit block is installed at the end of the rotating rod away from the torque disk.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a stepper motor torque testing mechanism, which has the following beneficial effects.

[0013] (1) Multiple motors to be tested are mounted on a fixed plate. The cylinder is started, and the piston rod of the cylinder drives the probe on the mounting plate to move towards the position of the motor to be tested, so that the probe is inserted into the power port of the motor. At this time, the motor is powered on, and the output end of the motor drives the torque disk to rotate. The torque disk drives the weight to move upward. If the motor torque is not qualified, the weight will not be able to be lifted or will stop in mid-air. If the motor torque is qualified, the weight will be pulled to the edge of the torque disk. The operation of using the motor to drive the weight is simple and low-cost. No professional knowledge or operating skills are required for the staff. The operation process is intuitive and easy to understand. At the same time, the structure is not easily affected by external factors, has strong stability, and improves the accuracy of motor torque testing.

[0014] (2) Using a cylinder to move the probe back and forth to realize the power-on and power-off operation of the motor can ensure that the probe is accurately inserted into the power-on port of the motor without manual operation, saving labor costs, improving work efficiency, and ensuring high safety. At the same time, it also provides sufficient space for the installation and removal of the motor under test, meeting the needs of torque detection of multiple motors.

[0015] (3) The setting of the limit block can prevent the torque disk from detaching from the main support plate, ensuring the smooth progress of the motor torque test. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Example:

[0022] like Figures 1-3 As shown, this utility model provides a stepper motor torque testing mechanism, including a fixed frame 1. Multiple motors 2 are detachably mounted on the fixed frame 1 by bolts. In this embodiment, the number of motors 2 is 5. The output end 3 of the motor 2 is connected to the torque disk 4 and drives the torque disk 4 to rotate. A heavy weight connecting wire 5 is wound on the annular groove 16 of the torque disk 4. A weight 6 is connected to the bottom of the connecting wire 5. The motor 2 is powered by a power supply device.

[0023] Furthermore, the power supply device includes a probe 7, a mounting plate 8, and a moving component 9. The probe 7 is fixedly mounted on the mounting plate 8 via an insulating needle sleeve 17. The mounting plate 8 is fixedly connected to the moving component 9. The moving component 9 drives the probe 7 to insert into the power supply port 10 at the bottom of the motor 2. The position of the probe 7 corresponds to the position of the power supply port 10.

[0024] Furthermore, the moving component 9 includes a cylinder 91 and a connecting rod 92. The cylinder body of the cylinder 91 is fixedly mounted on the support plate 18, and the support plate 18 is fixedly mounted on the main frame 111. One end of the connecting rod 92 is fixedly connected to the mounting plate 8, and the other end is fixedly connected to the piston rod of the cylinder 91 through the connecting plate 19. The bottom of the connecting plate 19 is slidably connected to the bottom of the cylinder 91.

[0025] Specifically, a slider 20 is fixedly installed at the bottom of the connecting plate 19, and a slide rail 21 is fixedly installed at the top of the cylinder 91. The slider 20 slides back and forth along the slide rail 21.

[0026] Furthermore, the mounting plate 8 has a groove 11, which provides installation space for the probe 7 so that it corresponds to the position of the power port 10.

[0027] Furthermore, the fixing frame 1 includes a main frame 111, a positioning plate 112, a fixing plate 113, and a main support plate 114. The positioning plate 112, the fixing plate 113, and the main support plate 114 are sequentially fixedly installed on the main frame 111. The motor 2 is detachably installed on the fixing plate 113. The torque disk 4 is rotatably installed on the main support plate 114. The connecting rod 92 passes through the positioning plate 112 and the main support plate 114 in sequence and is connected to the piston rod of the cylinder 91.

[0028] The connecting rod 92 passes through the positioning plate 112 and the main support plate 114 in sequence, which can play a good guiding role in the movement direction of the connecting rod 92 and prevent the movement direction of the connecting rod 92 from deviating, thereby affecting the normal power-on operation of the motor 2.

[0029] Furthermore, the output end 3 of the motor 2 has a flat structure, and the center of the torque disk 4 is provided with a socket 12 that matches the output end 3. The flat structure design enables quick insertion and positioning of the motor 2 and the torque disk 4, which is beneficial for the motor 2 to drive the torque disk 4 to rotate.

[0030] Furthermore, a rotating rod 13 is fixedly mounted on the torque disk 4. The rotating rod 13 is rotatably connected to the main support plate 114 via a bearing 14, enhancing the smoothness of the rotation process of the torque disk 4. A limit block 15 is installed at the end of the rotating rod 13 away from the torque disk 4. The limit block 15 prevents the torque disk 4 from detaching from the main support plate 114, ensuring the smooth progress of the motor torque test.

[0031] The working principle is as follows:

[0032] Five motors 2 to be tested are mounted on the fixing plate 113, with the output end 3 of the motor 2 inserted into the insertion hole 12 of the torque disk 4. The corresponding start button 22 is pressed, activating the corresponding cylinder 91. The piston rod of the cylinder 91 drives the connecting plate 19-connecting rod 92-mounting plate 8-insulating needle sleeve 17-probe 7 to move towards the position of the motor under test, i.e., backward, thus inserting the probe 7 into the power port 10 of the motor 2. At this time, the motor 2 is energized, and the output end 3 of the motor 2 drives the torque disk 4 to rotate, which in turn drives the weight 6 to move upward. If the torque of the motor 2 is unqualified, the weight 6 will not be able to be lifted or will stop in mid-air. If the torque of the motor 2 is qualified, the weight 6 will be pulled all the way to the edge of the torque disk 4. After making the judgment, the start button 22 is pressed again, causing the cylinder 91 to move the probe 7 forward, removing the motor 2 under test. The unqualified motor 2 is then selected, thus completing one test cycle.
