[0002] The Chinese utility model patent with patent number ZL202323334172.6 and patent name, entitled "Motor Torque Testing Fixture," specifically discloses the following technical solution: A motor torque testing fixture includes a base, a translation component, and a clamping component. A support plate is provided on the right end of the upper surface of the base. A coupling is rotatably connected to the upper end of the support plate. A torque meter is provided on the right side of the support plate. The drive shaft of the torque meter is fixedly connected to the right end of the coupling. A transmission rod is provided inside the left end of the coupling. A second support plate is provided in the middle of the upper surface of the base. A bearing is provided inside the upper end of the second support plate. The outer arc surface of the transmission rod is fixedly connected to the inner arc surface of the inner ring of the bearing. A connector is sleeved on the left end of the transmission rod. Support legs are symmetrically provided on the left end of the upper surface of the base. The upper ends of the support legs are fixedly connected to the lower surface of the platform. A lifting screw is threadedly connected to the middle of the support legs. The translation component is rotatably connected to the upper end of the lifting screw, and the clamping component is slidably connected to the upper end of the translation component.

[0003] In the process of testing the motor torque using the aforementioned motor torque testing fixture, the motor product is clamped and fixed by the clamping assembly, and the position of the motor product is adjusted by the translation assembly and the lifting screw so that the output shaft of the motor is inserted into the positioning groove set at the left end of the connector, and the hexagonal blind hole at the right end of the connector is connected to the transmission rod. When the motor is started, the output shaft of the motor transmits the torque to the drive shaft of the torque meter in sequence through the connector, the transmission rod and the coupling, so as to test the torque of the motor product by the torque meter.

[0004] It should be noted that the above-mentioned motor torque testing fixture still has the following defects: When testing the torque of a motor product, the output shaft of the motor product is connected to the drive shaft of the torque meter through a connector and a transmission rod. The output shaft, connector, and transmission rod of the motor product are connected in sequence. That is, this motor torque testing fixture is only suitable for motor products with direct output shaft, and not for motor products with gear output.

[0005] In view of the above situation, it is necessary to develop a torque (force) measuring device for motor products with gear output. Utility Model Content

This stepper motor gear output torque measuring device has a novel structural design, is easy to operate and use, and can effectively measure the torque of motor products with gear output.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution.

Detailed Implementation

[0025] The present invention will now be described in conjunction with specific embodiments.

[0026] Example 1, as Figures 1 to 4 As shown, a stepper motor gear output torque measuring device includes a base 1, a support plate 2, a torque meter 3, and a transmission rod 4. The support plate 2 is screwed and fastened to the base 1, and one end of the transmission rod 4 is connected to the drive shaft of the torque meter 3.

[0027] Among them, such as Figure 1and Figure 3 As shown, the upper end of the support plate 2 is screwed with a fixed plate 5. The fixed plate 5 has a vertical through-hole 51. The torque meter 3 is arranged vertically and the upper end of the torque meter 3 is fixed in the fixed hole 51 by a locking screw 6.

[0028] Furthermore, such as Figures 1 to 4 As shown, the transmission rod 4 is arranged vertically, and the lower end of the transmission rod 4 is fastened with a test gear 7.

[0029] Furthermore, such as Figures 1 to 4 As shown, a motor shifting mechanism 8 is installed on the front end of the support plate 2 on the base 1. A motor positioning block 91 is installed on the upper end of the motor shifting mechanism 8. The motor positioning block 91 is equipped with at least two motor positioning columns 92 arranged at intervals.

[0030] It should be noted that, in the process of measuring the torque of the motor product 10 using the stepper motor gear output torque measuring device of this embodiment, the steps include:

[0031] Step a: Place the motor product 10 on the motor positioning block 91, and insert the motor positioning post 92 of the motor positioning block 91 into the structural hole 103 of the bracket 102 of the motor product 10, so as to achieve the positioning of the motor product 10 by the cooperation of the motor positioning post 92 with the structural hole 103 of the motor product 10.

[0032] Step b: After the motor product 10 is positioned on the motor positioning block 91, operate the motor shifting mechanism 8 to move the motor product 10 backward, thereby making the output gear 101 of the motor product 10 mesh with the test gear 7 on the transmission rod 4.

[0033] Step c: Start the motor product 10 and make the output gear 101 rotate. The output gear 101 drives the test gear 7 to rotate, which in turn makes the transmission rod 4 rotate. During this process, the output torque of the output gear 101 of the motor product 10 is amplified by the gear transmission pair composed of the output gear 101 and the test gear 7 and is finally reflected in the reading of the torque meter 3. The output torque of the motor product 10 = the reading of the torque meter 3 * the gear meshing ratio * the transmission efficiency.

[0034] Step d: After the motor product 10 completes the torque measurement, operate the motor shifting mechanism 8 to move the motor positioning block 91 and the motor product 10 forward. The output gear 101 of the motor product 10 will disengage from the test gear 7. Then, remove the motor product 10 from the motor positioning block 91.

[0035] It should be emphasized that the motor positioning block 91 and the motor positioning column 92 of this embodiment can cooperate to realize the rapid positioning and placement of the motor product 10, and the output gear 101 can be engaged with the test gear 7 and moved away by operating the motor shifting mechanism 8, which is convenient to operate and use.

[0036] In summary, the stepper motor gear output torque measuring device of this embodiment has the advantages of novel structural design and convenient operation, and can effectively measure the torque of the gear output motor product 10.

The fixed guide rail 81, the movable slider 82 and the locking mechanism together form a locking guide rail slider pair; the motor positioning block 91 is screwed and fastened to the upper surface of the movable slider 82.

[0038] It should be explained that the locking guide rail slider pair is already existing technology, and will not be elaborated here.

[0039] When the motor shifting mechanism 8 is operated to make the output gear 101 mesh with the test gear 7, the movable slider 82 is moved backward along the fixed guide rail 81, and the motor positioning block 91 and the positioned motor product 10 are moved forward; after the output gear 101 of the motor product 10 meshes with the test gear 7, the locking mechanism of the movable slider 82 is adjusted to the locking state and the movable slider 82 is locked and fixed, so that the output gear 101 of the motor product 10 and the test gear 7 remain in the meshing state during the test.

[0040] Example 3, as Figure 2 and Figure 4 As shown, the difference between this embodiment 3 and embodiment 1 is that: the base 1 has an upward-opening bearing mounting hole 11 directly below the transmission rod 4, and a ball bearing 12 is embedded in the bearing mounting hole 11. The lower end of the transmission rod 4 is mounted on the base 1 through the ball bearing 12.

[0041] Example 4, as Figure 1 and Figure 3 As shown, the difference between this embodiment four and embodiment one is that: the fixing plate 5 has two internal threaded holes 52 arranged opposite each other and opening outwards respectively.
