Because the products are of different sizes, they may become loose or unable to be installed.

[0004] Therefore, this utility model provides a servo motor testing device. Utility Model Content

[0009] Preferably, the drive assembly includes a pair of fixing bars fixed to the bottom of the first sliding blocks, the bottom of the fixing bars having a moving groove, a concave frame fixed to the bottom of the mounting plate, and a stepper motor fixed to the top of the concave frame laterally.

[0010] Preferably, the output end of the stepper motor is provided with a drive rod, the top of the drive rod is fixedly connected to a rotating bar, and the top of both ends of the rotating bar are fixedly connected to circular blocks, which are slidably connected in the moving groove.

[0011] Preferably, the drag assembly includes a concave plate fixed to the top of the mounting plate, a set of electric actuators fixed to the bottom of the concave plate, a rectangular plate fixed to the telescopic end of the set of electric actuators, a test motor fixed to the rectangular plate, and an elastic coupling mounted on the output shaft of the test motor.

[0012] Preferably, the clamping plate has a second sliding groove, a second sliding block is slidably connected in the second sliding groove, a circular rod is slidably connected to the second sliding block through a circular hole, and a lower pressure plate is fixedly connected between a group of the circular rods.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown, a servo motor testing device according to an embodiment of the present invention includes a mounting plate 1, a pair of fixing plates 2 fixed to the top of the mounting plate 1, an isosceles groove 3 formed on the fixing plate 2, and a testing mechanism provided on the top of the mounting plate 1. The testing mechanism includes:

[0025] The clamping assembly includes a set of first sliding grooves 4 opened on the mounting plate 1, a first sliding block 5 slidably connected in the first sliding groove 4, a clamping plate 6 fixedly connected to the top of a pair of first sliding blocks 5, and a driving assembly for moving a set of first sliding blocks 5 at the bottom of the mounting plate 1.

[0026] The drag assembly is mounted on top of mounting plate 1 for testing the servo motor.

[0027] During operation, the set drive component drives a set of sliding blocks to move, thereby enabling a pair of clamping plates 6 to move relative to each other and clamp the servo motor to be tested. This solves the problem in the prior art that, due to the certain differences in the size of the tested products, the existing device cannot be installed on different tested products, resulting in certain limitations during testing and low practicality of the device. The problem of loosening or inability to install the device due to the size of the product is also addressed.

[0028] The drive assembly includes a pair of first sliding blocks 5 with a fixed strip 7 fixed to the bottom. The fixed strip 7 has a moving groove 8 at the bottom. The mounting plate 1 has a concave frame 9 fixed to the bottom. The concave frame 9 has a stepper motor 10 fixed to the top horizontally. The output end of the stepper motor 10 is provided with a drive rod 11. The top of the drive rod 11 is fixed with a rotating strip 12. The tops of both ends of the rotating strip 12 are fixed with circular blocks 13. The circular blocks 13 are slidably connected in the moving groove 8.

[0029] During operation, the stepper motor 10 drives the drive rod 11 to rotate, causing the rotating bar 12 to rotate. This allows a pair of fixed bars 7 to move along the first sliding groove 4 via the circular block 13 that is slidably connected in the moving groove 8. This enables the fixing of servo motors of different sizes, and the operation is simple.

[0030] The towing assembly includes a concave plate 14 fixed to the top of the mounting plate 1, a set of electric actuators 15 fixed to the bottom of the concave plate 14, a rectangular plate 16 fixed to the telescopic end of the set of electric actuators 15, a test motor 17 fixed to the rectangular plate 16, and a flexible coupling 25 installed on the output shaft of the test motor 17.

[0031] During operation, a set of electric actuators 15 drives the rectangular plate 16 to rise and fall, thereby enabling the test motor 17 to adjust its height according to different models of servo motors, so that it can be accurately aligned with the servo motor to be tested. It can be connected by a flexible coupling 25 that can connect shafts of different diameters.

[0032] A second sliding groove 18 is provided on the clamping plate 6. A second sliding block 19 is slidably connected in the second sliding groove 18. A circular rod 20 is slidably connected to the second sliding block 19 through a circular hole. A lower pressure plate 21 is fixedly connected between a group of circular rods 20. A threaded rod 22 is rotatably connected to the top of the lower pressure plate 21. A rotary valve 23 is fixedly connected to the top of the threaded rod 22. A pair of clamping plates 6 are slidably connected to a support plate 24 through a rectangular hole. The support plate 24 is threadedly connected to the threaded rod 22 through a threaded hole.

[0033] During operation, the lower pressure plate 21 can be raised and lowered by the second sliding block 19 slidably connected to the clamping plate 6, which can press down on the top of the servo motor. This can prevent the servo motor from tilting or tilting during clamping due to the squeezing force, thus achieving precise positioning and correct connection with the flexible coupling 25.

[0034] Working principle: The set drive component drives a set of sliding blocks to move, thereby enabling a pair of clamping plates 6 to move relative to each other and clamp the servo motor to be tested. This solves the problem in the existing technology that the existing device cannot install on different products due to the certain differences in the size of the tested products, resulting in certain limitations during testing and low practicality of the device. The problem of loosening or inability to install due to the size of the product is also solved.

[0035] The stepper motor 10 drives the drive rod 11 to rotate, causing the rotating bar 12 to rotate. This allows a pair of fixed bars 7 to move along the first sliding groove 4 via the circular block 13 that is slidably connected in the moving groove 8. This enables the fixing of servo motors of different sizes, and the operation is simple.

[0036] By setting up a set of electric actuators 15 to drive the rectangular plate 16 to rise and fall, the test motor 17 can be height adjusted according to different models of servo motors, so that it can be accurately aligned with the servo motor to be tested on the same axis. It can be connected by a flexible coupling 25 that can connect shafts of different diameters.

[0037] The second sliding block 19, which is slidably connected to the clamping plate 6, allows the pressure plate 21 to be raised and lowered, thereby pressing down on the top of the servo motor. This prevents the servo motor from tilting or tilting during clamping due to the squeezing force, thus achieving precise positioning and ensuring correct connection with the flexible coupling 25.
