[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5As shown, this embodiment provides a load testing fixture for a geared motor, including a workbench 1. Considering that traditional testing fixtures often lack sufficient adaptability and are difficult to meet diverse testing needs, a moving mechanism 2 is detachably installed on the top of the workbench 1. A fixed base 3 is installed on the top of the moving mechanism 2. The fixed base 3 has a placement slot 34 for fixing the geared motor 6 inside. A coupling 4 is installed at the output end of the hysteresis dynamometer 5. The coupling 4 is positioned opposite to the placement slot 34. The connection between the fixed base 3 and the moving mechanism 2 is simple, which facilitates the preparation of the geared motor 6 by the operator before testing, improves testing efficiency, and allows for adjustment of the geared motor 6's position in all directions and height through the moving mechanism 2, increasing the flexibility of the testing fixture. This facilitates load testing of different types and specifications of geared motors 6, increases the applicability of the testing fixture, effectively reduces the cost for enterprises to equip different models of motors with dedicated fixtures, reduces the idle rate of the fixture equipment, and improves equipment utilization.

[0017] The improvements in this embodiment are as follows: by setting up various fixed seats 3 with different structures to meet the clamping and fixing of different types and specifications of geared motors 6, the applicability of the testing fixture is increased; the moving mechanism 2 can adjust the lateral and vertical positions of the geared motor 6 to be tested, increasing the flexibility of the testing fixture during use, greatly shortening the preparation time before testing, and improving testing efficiency; precise position adjustment can ensure that the geared motor 6 maintains the ideal installation posture during testing, reducing testing errors caused by position deviations, and making the testing data more accurate and reliable.

[0018] Specifically, in order to flexibly and conveniently adjust the position of the geared motor 6, the workbench 1 is provided with a number of mounting holes 101, and the bottom of the moving mechanism 2 is provided with a number of fixing holes 201. The moving mechanism 2 is installed and fixed to the workbench 1 by fastening bolts passing through the fixing holes 201 and the mounting holes 101. The moving mechanism 2 includes a connecting seat 21, which is located on the top of the workbench 1, and the fixing holes 201 pass through the connecting seat 21. A first movable seat 23 is slidably mounted on the upper end of the connecting seat 21. A second movable seat 24 is slidably connected to the upper end of the first movable seat 23. The sliding directions of the first movable seat 23 and the second movable seat 24 are perpendicular. Guide rails 22 are symmetrically fixedly connected to the top of the connecting seat 21. The bottom of the first movable seat 23 slides in cooperation with the guide rails 22. By adjusting the left and right positions of the first movable seat 23, the distance between the geared motor 6 and the coupling 4 can be adjusted. A rotating component 25 is engaged with the first movable seat 23. The rotating component 25 is meshed with the second movable seat 24. The rotating component 25 drives the second movable seat 24 to slide relative to the first movable seat 23. By rotating the rotating component 25, the second movable seat 24 moves stably inside the first movable seat 23, thereby adjusting the front and rear positions of the geared motor 6. A mounting seat 26 is fixedly connected to the top of the second movable seat 24. Mounting base 26 has an upward-opening insertion slot 261; the lower part of the mounting base 3 extends downward and has an insertion part 31, which slides into the insertion slot 261. Mounting base 26 has strip-shaped holes 262 on opposite sides, the extension direction of which is consistent with the sliding direction of the insertion part 31. The insertion part 31 has several positioning holes 311, which are aligned with the strip-shaped holes 262, allowing external bolts to be inserted to adjust and fix the mounting base 3 to the mounting base 26. Adjusting the height of the mounting base 3 adjusts the height of the geared motor 6. The positioning holes 31 are fixedly connected to the mounting base 26 by external bolts. The overall structure is simple, the connection is stable, and the testing efficiency is improved. Precise position adjustment ensures that the geared motor 6 maintains an ideal installation posture during testing, reducing testing errors caused by positional deviations and making the testing data more accurate and reliable.

[0019] Considering the different sizes of the geared motors 6, in order to ensure that the fixing seat 3 can stably clamp and fix the geared motors 6 of different specifications, the upper end of the fixing seat 3 is provided with a threaded rod 33 meshing downwards, and the lower end of the threaded rod 33 is fixedly provided with a fastening rubber pad 32. The fastening rubber pad 32 is located above the placement groove 34. By rotating the threaded rod 33 to move up and down, the fastening rubber pad 32 is driven to move up and down, so as to satisfy the fastening rubber pad 32 to quickly clamp and fix the geared motor 6 and ensure the stability of the geared motor 6 during the testing process.

[0020] Considering that the coupling 4 needs to be connected to the output ends of different specifications of geared motors 6, the coupling 4 is fixedly connected to the output shaft of the geared motor 6 through connectors 41. There are multiple connectors 41 with different internal hole diameters. According to the shape of the output shaft end of different geared motors 6, the connector 41 with the matching hole diameter of the output shaft end of the geared motor 6 is selected to connect the coupling 4 and the geared motor 6. It is no longer necessary to replace the entire coupling 4, which ensures that multiple geared motors 6 can be tested while reducing the cost of testing tooling.

[0021] It should be noted that, in this embodiment, the placement groove 34 in the fixed base 3 can be a straight groove or an L-shaped groove. The placement groove 34 with a straight groove can stably place the linear geared motor 6, so as to realize the load detection work of the testing fixture on the linear geared motor 6; the placement groove 34 with an L-shaped groove can stably place the L-shaped geared motor 6, so as to realize the load detection work of the testing fixture on the L-shaped geared motor 6.

[0022] In summary, the working principle of this solution is as follows: First, select a mounting base 3 with a corresponding placement slot 34 structure according to the different types and specifications of the geared motor 6. Place the geared motor 6 in the placement slot 34, then rotate the threaded rod 33 to push the fastening pad 32 down to clamp and fix the geared motor 6. Next, install the lower end of the mounting base 3 inside the mounting base 26. By moving the mounting base 3 up and down, the height position of the geared motor 6 can be adjusted. After determining the height position, connect it to the external bolt through the positioning hole 31 to stably install it inside the mounting base 26. Push the first moving seat 23 to slide left and right above the guide rail 22 to adjust the distance between the geared motor 6 and the coupling 4. The rotating part 25 is threadedly connected to the first moving seat 23. Rotating the rotating part 25 drives the second moving seat 24 to move stably inside the first moving seat 23, thereby realizing the adjustment of the front and rear position of the geared motor 6. The design enhances the flexibility of the testing fixture, significantly shortens preparation time, and improves testing efficiency. Precise position adjustment ensures the geared motor 6 maintains an ideal installation posture during testing, reducing testing errors caused by positional deviations and making test data more accurate and reliable. Depending on the shape of the output shaft end of different geared motors 6, a connector 41 with a matching bore diameter is selected for connecting the coupling 4 to the geared motor 6, eliminating the need to replace the entire coupling 4. This ensures the ability to test various geared motors 6 while reducing the cost of the testing fixture. The overall structure enables load testing of various geared motors 6, increasing the applicability of the testing fixture, effectively reducing the cost for companies to equip different models of motors with dedicated fixtures, reducing equipment idle time, and improving equipment utilization.
