[0035] Workbench 1;

[0036] A positioning plate 2, which is vertically arranged on the workbench 1 and has a through hole in the middle thereof;

[0038] A coupling 6, which is arranged on a side of the positioning plate 2 away from the mounting plate 3 and connected to a first linear drive mechanism arranged on the workbench 1, and the first linear drive mechanism drives the coupling 6 to approach or move away from the mounting plate 3;

[0039] The clamping block 7 is arranged on a side of the positioning plate 2 close to the mounting plate 3 and is detachably connected to a second linear drive mechanism arranged on the workbench 1, and the second linear drive mechanism drives the clamping block 7 to move closer to or away from the mounting plate 3. In order to prevent the clamping block 7 from damaging the cylinder of the servo motor, the clamping block 7 can be made of a non-hard material with a certain elasticity, such as rubber.

[0040] In this embodiment, the mounting plate 3 is detachably connected to the workbench 1, and multiple mounting plates 3 can be set, corresponding to a variety of servo motors of different sizes. The first groove 4 and the second groove 5 on each mounting plate 3 are set according to the actual size of the servo motor, ensuring that the servo motor is coaxially interfaced with the coupling 6 when placed on the mounting plate 3, so that the test bracket can be used for testing more servo motors of different sizes. The second notch is close to the opening of one end of the positioning plate 2, so that when the flange of the servo motor is placed in the second groove 5, the flange and the positioning plate 2 fit together, and the output shaft of the servo motor passes through the through hole on the positioning plate 2. Thus, the clamping block 7 can be driven to move by the second driving mechanism, and the clamping block 7 drives the flange and the positioning plate 2 to collide, and the servo motor is clamped by the clamping block 7 and the positioning plate 2, so as to quickly fix it, and then the coupling 6 is driven by the first driving mechanism to be connected to the output shaft of the servo motor and close to the servo motor.

[0041] Preferably, as another embodiment of the utility model, in the bracket for testing a servo motor, a plurality of first mounting holes are provided on the mounting plate 3 at intervals, a plurality of first threaded holes corresponding to and corresponding to the number of the first mounting holes are provided on the workbench 1, and a first bolt 8 is installed in the first threaded hole, and the first bolt 8 passes through the corresponding first mounting hole.

[0042] In this embodiment, the mounting plate 3 can be a square plate body, and first mounting holes are set at its four right angles. The first bolts 8 pass through the first mounting holes and are threadedly connected to the first threaded holes. By tightening multiple first bolts 8, the mounting plate 3 can be fixed on the workbench 1.

[0043] Preferably, as another embodiment of the utility model, in the bracket for testing a servo motor, the first linear drive mechanism comprises:

[0044] A first threaded rod 9, wherein the workbench 1 is provided with a first slide groove 10, wherein the first threaded rod 9 is horizontally arranged in the first slide groove 10, wherein one end of the first threaded rod 9 is rotatably connected to the workbench 1, and the other end of the first threaded rod 9 passes through the workbench 1 and is rotatably connected thereto;

[0045] A first threaded sleeve 11, which is threadedly mounted on the first threaded rod 9;

[0046] A first sliding block 12 is slidably disposed in the first sliding groove 10, and the first threaded sleeve 11 passes through the first sliding block 12 and is connected thereto;

[0047] The docking joint 13 is arranged at the upper end of the first sliding block 12 and connected to the coupling 6 .

[0048] In this embodiment, the two ends of the first slider 12 fit with the inner walls of the first chute 10, so that the first slider 12 can be limited and moved along the length direction of the first chute 10. When the first threaded rod 9 is rotated by an external force, the first threaded sleeve 11 connected to the first slider 12 will not rotate because the first chute 10 limits the rotation of the first slider 12. Therefore, the first threaded sleeve 11 connected to the first slider 12 will not rotate, and thus move linearly along the axis of the first threaded rod 9, thereby driving the first slider 12 to move horizontally, and driving the docking joint 13 and the coupling 6 thereon to move.

[0049] Preferably, as another embodiment of the utility model, in the bracket for servo motor testing, first limiting grooves 14 are provided on the side walls of both sides of the first slide groove 10, and first protrusions are respectively provided at both ends of the first slider 12, and the two first protrusions are respectively slidably arranged in the two first limiting grooves 14.

[0050] In this embodiment, by providing two first limiting grooves 14 , the first slider 12 is slidably connected to the two first limiting grooves 14 via two first protrusions, so that the movement track of the first slider 12 can be more stable.

[0051] Preferably, as another embodiment of the utility model, in the bracket for testing a servo motor, the second linear drive mechanism comprises:

[0052] A second threaded rod 15, wherein the workbench 1 is provided with a second slide groove 16, wherein the second threaded rod 15 is horizontally arranged in the second slide groove 16, wherein one end of the second threaded rod 15 is rotatably connected to the workbench 1, and the other end of the second threaded rod 15 passes through the workbench 1 and is rotatably connected thereto;

[0056] In this embodiment, the two ends of the second sliding block 18 are in contact with the inner walls of the second sliding groove 16.

[0057] Thus, the second slider 18 can be limited to move along the length direction of the second slide groove 16. When the second threaded rod 15 is rotated by external force, the second threaded sleeve 17 connected to the second slider 18 will not rotate because the second slide groove 16 limits the rotation of the second slider 18. Therefore, the second threaded sleeve 17 will move linearly along the axis of the second threaded rod 15, thereby driving the second slider 18 to move horizontally, and driving the support 19 and the clamping block 7 thereon to move.

[0058] Preferably, as another embodiment of the utility model, in the bracket for servo motor testing, second limiting grooves 20 are provided on the side walls of both sides of the second slide groove 16, and second protrusions are respectively provided at both ends of the second slider 18, and the two second protrusions are respectively slidably arranged in the two second limiting grooves 20.

[0060] Preferably, as another embodiment of the utility model, in the bracket for testing a servo motor, the support 19 is provided with a plurality of second threaded holes at intervals at one end close to the positioning plate 2, the clamping block 7 is connected to a base plate, the base plate is provided with a plurality of second mounting holes corresponding to the number of the second threaded holes and one-to-one, second bolts 21 are installed in the second threaded holes, and the second bolts 21 pass through the corresponding second mounting holes.
