[0018] The following further describes the present utility model in detail with reference to the accompanying drawings, so that those skilled in the art can implement it according to the text of the specification.

[0019] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0020] Figures 1-3 A servo motor test tooling provided by an embodiment of the present utility model includes a workbench 1 and a horizontal movement mechanism, a servo motor fixing mechanism, and a height adjustment mechanism provided thereon. The height adjustment mechanism is connected to the horizontal movement mechanism, and the horizontal movement mechanism drives the height adjustment mechanism to approach or move away from the servo motor fixing mechanism. A horizontally arranged coupling mechanism is detachably connected to the height adjustment mechanism, and a rotary encoder 2 is installed on the coupling mechanism. The height adjustment mechanism drives the coupling mechanism to move up and down.

[0021] In this embodiment, the servo motor is fixed on the servo motor fixing mechanism, and then the horizontal movement mechanism drives the height adjustment mechanism to approach the output shaft of the servo motor. According to the height of the output shaft of the servo motor, the height of the coupling mechanism is adjusted so that the coupling mechanism is coaxial with the output shaft of the servo motor. Then, the horizontal movement mechanism drives the height adjustment mechanism to move further towards the output shaft of the servo motor so that the output shaft of the servo motor is connected to the coupling mechanism. When detecting the rotational speed of the servo motor, the servo motor drives the input shaft of the rotary encoder 2 on the coupling mechanism to rotate. The rotary encoder 2 is electrically connected to an external control device and sends a signal thereto, thereby obtaining the rotational speed information of the servo motor.

[0022] Preferably, as another embodiment of the present utility model, the height adjustment mechanism includes a support seat 3, a moving block 4, and a driving component. The support seat 3 is connected to the horizontal movement mechanism and has a notch thereon. The moving block 4 is slidably arranged up and down in the notch and is connected to the driving component. The coupling mechanism is arranged on the moving block 4.

[0023] In this embodiment, as Figure 3 shown, the driving assembly includes a threaded rod 8, a limiting rod 9 and a driving motor 10. The limiting rod 9 is vertically arranged in the notch and vertically penetrates through the moving block 4. The upper end of the threaded rod 8 is in transmission connection with the driving motor 10 arranged on the support base 3, and its lower end is rotatably connected to the bottom wall of the notch. A threaded sleeve is threadedly installed on the threaded rod 8. The threaded sleeve vertically penetrates through the moving block 4 and is connected thereto. When the driving motor 10 works, it drives the threaded rod 8 to rotate. Since the moving block 4 can only move up and down, at this time, the threaded sleeve rotates relative to the threaded rod 8 under the limitation of the moving block 4, thereby driving the moving block 4 to move up and down.

[0024] Preferably, as another embodiment of the present invention, the coupling mechanism includes a bearing seat 5, a rotating shaft 6 and a connecting bracket 7. An installation hole is provided on the moving block 4. The bearing seat 5 is arranged in the installation hole. The rotating shaft 6 is coaxially arranged in the bearing seat 5. The rotary encoder 2 is connected to the moving block 4 through the connecting bracket 7 and is coaxially connected to one end of the rotating shaft 6. A connecting shaft is coaxially provided at the other end of the rotating shaft 6, and a coupling 16 is provided on the connecting shaft.

[0025] In this embodiment, the rotating shaft 6 is rotatably connected to the moving block 4 through the bearing seat 5. One end of it is connected to the main shaft of the rotary encoder 2, and a connecting shaft is coaxially provided at the other end. The coupling 16 on the connecting shaft is coaxially connected to the input shaft of the servo motor on the servo motor fixing mechanism, realizing the connection between the rotating shaft 6 and the output shaft of the servo motor. In this way, when the output shaft of the servo motor rotates, the rotating shaft 6 rotates synchronously, and the rotary encoder 2 can detect its rotation speed, and thus the rotation speed of the output shaft of the servo motor can be obtained.

[0026] Preferably, as another embodiment of the present invention, the horizontal moving mechanism includes a sliding seat 11 and a positioning component. The sliding seat 11 is slidably connected to the workbench 1 and is connected and fixed to the workbench 1 at any position of its movement through the positioning component.

[0027] In this embodiment, as Figures 1-3 shown, the sliding seat 11 is slidably connected to the workbench 1. The workbench 1 is square. A chute corresponding to the workbench 1 can be provided at the lower end of the movable seat. Through the chute, the sliding between the sliding seat 11 and the workbench 1 is more stable. Then, the positioning component adopts a plurality of positioning bolts. A plurality of threaded positioning holes are provided on both side walls of the chute. The positioning bolts are threadedly installed in the threaded positioning holes. Tighten the plurality of positioning bolts until their ends abut against the workbench 1, so that the sliding seat 11 can be fixed to the workbench 1.

[0028] Preferably, as another embodiment of the present invention, as Figure 4As shown, the servo motor fixing mechanism includes a positioning plate 12 and a mounting plate 13. The positioning plate 12 is vertically arranged on the mounting plate 13 and has a through hole in the middle thereof. The mounting plate 13 is detachably arranged on the workbench 1. The upper end of the mounting plate 13 is provided with a first groove 14 and a second groove 15 corresponding to the outer shell and the flange of the servo motor respectively.

[0029] In this embodiment, by providing the first groove 14 and the second groove 15 at the upper end of the mounting plate 13 for quick positioning with the outer shell and the flange of the servo motor, the output shaft of the servo motor passes through the through hole in the middle of the positioning plate 12, and the flange of the servo motor and the mounting plate 13 are connected by the existing bolt connection method, so that the servo motor can be fixed. In this embodiment, multiple sets of servo motor fixing mechanisms with different sizes are provided, corresponding to servo motors of different sizes respectively, and the servo motor fixing mechanism can be replaced as needed. When fixing the mounting plate 13, a plurality of mounting holes are provided at intervals on the mounting plate 13, and a plurality of threaded holes corresponding in number and one-to-one to the mounting holes are provided on the workbench 1. Bolts are installed in the threaded holes and penetrate through the corresponding mounting holes.

[0030] Although the embodiments of the present invention have been disclosed as above, it is not limited to the applications listed in the specification and the embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the embodiments shown and described here.
