However, in order to keep the axis of the new energy motor and the test equipment aligned, the device needs to clamp the new energy motor in the center, and also needs to adjust the position of the test equipment, which is inconvenient to operate; and the lack of a basic positioning structure makes the clamping adjustment distance of the motor longer.

[0011] Furthermore, an adjusting bolt for adjusting the elastic force of the preload spring is installed on the fixed end plate, and the end of the adjusting bolt is connected to a mounting slot body, and one end of the preload spring is installed in the mounting slot body.

[0012] Furthermore, the transverse clamping plate comprises a straight section and an arc section, the arc section is connected to one end of the straight section, and the distance between the arc sections of the two transverse clamping plates increases gradually from the connecting end to the opposite end.

[0030] Example 1: Please refer to the attached Figure 1 and attached Figure 2 A fixed tooling for new energy motor drive testing includes a table plate 6 for carrying the new energy motor, and a clamping mechanism for clamping the new energy motor is provided on the table plate 6. The clamping mechanism can stably clamp the new energy motor and align the axis of the new energy motor with the test equipment; the table plate 6 can translate and slide on the test bench toward the side where the test equipment is located to facilitate the docking of the new energy motor and the test equipment.

[0031] A calibration plate 5 is fixed to the front end side of the table 6, and a calibration hole 51 is opened on the calibration plate 5 for the output shaft of the new energy motor to pass through. The calibration hole 51 is coaxially arranged with the docking end of the test equipment, so that the new energy motor only needs to be clamped to be coaxial with the calibration hole 51; and the diameter of the calibration hole 51 is equal to the diameter of the output shaft of the new energy motor of the largest specification, so as to adapt to new energy motors of different specifications.

[0032] The clamping mechanism includes a transverse centering clamping assembly and a vertical centering clamping assembly, and the intersection of the center plane of the transverse centering clamping assembly and the center plane of the vertical centering clamping assembly coincides with the axis of the calibration hole 51. In this way, the new energy motor can be clamped and fixed simultaneously by the transverse centering clamping assembly and the vertical centering clamping assembly to ensure that the motor output shaft is coaxial with the calibration hole 51.

[0033] In this embodiment, please refer to the attached Figure 1 -Attached Figure 3The vertical centering clamping assembly includes an upper clamping plate 1 and a lower clamping plate 4 arranged in parallel, and a bidirectional lead screw slider structure 2 for driving the upper clamping plate 1 and the lower clamping plate 4 to move synchronously in opposite directions.

By driving the bidirectional screw slider structure 2, the upper clamping plate 1 and the lower clamping plate 4 can be driven to move toward each other to realize the vertical clamping of the new energy motor, and make the axis of the output shaft of the new energy motor and the axis of the calibration hole 51 in the same horizontal plane, that is, to realize vertical centering clamping; at the same time, because the two preload springs 3 of the transverse centering clamping assembly apply the same elastic force on the two opposite sides of the new energy motor through the transverse clamping plate 7, the transverse clamping of the new energy motor is realized, and the axis of the output shaft of the new energy motor and the axis of the calibration hole 51 are in the same vertical plane, that is, to realize transverse centering clamping. The combined effects of the two sets of centering clamping assemblies can make the new energy motor coaxial with the calibration hole 51.

[0034] In this embodiment, please refer to the attached Figure 2 The upper clamping plate 1 and the lower clamping plate 4 are both provided with a bidirectional lead screw slider structure 2 at both ends, and the two sets of bidirectional lead screw slider structures 2 are simultaneously driven by a driving motor 11, and the driving motor 11 is connected to the two bidirectional lead screws through a belt transmission structure. The two sets of bidirectional lead screw slider structures 2 can drive the upper clamping plate 1 and the lower clamping plate 4 more stably, and are also conducive to ensuring the balance of the device.

[0035] In this embodiment, please refer to the attached Figure 1 and attached Figure 2 The two ends of the table plate 6 are connected with side plates 10 extending vertically upward, and the side plates 10 are "L"-shaped. The bidirectional screw slider structure 2 is connected to the side plates 10; the bottom of the table plate 6 is connected to the mounting frame 9, and the driving motor 11 of the vertical centering clamping assembly is installed in the mounting frame 9.

[0036] When in use, first place the new energy motor between two transverse clamping plates 7, and insert the output shaft of the new energy motor into the calibration hole 51, so that the position of the new energy motor is basically determined, and only fine-tuning is required in the subsequent clamping process. And the two preload springs 3 exert equal elastic force on the two opposite sides of the new energy motor through the transverse clamping plates 7 to achieve the lateral clamping of the new energy motor, and make the axis of the output shaft of the new energy motor and the axis of the calibration hole 51 in the same vertical plane, that is, to achieve lateral centering clamping; then start the bidirectional screw slider structure 2, which can drive the upper clamping plate 1 and the lower clamping plate 4 to move toward each other to achieve vertical clamping of the new energy motor, and make the axis of the output shaft of the new energy motor and the axis of the calibration hole 51 in the same horizontal plane, that is, to achieve vertical centering clamping; the clamping effect of the two sets of centering clamping components can make the new energy motor coaxial with the calibration hole 51. Finally, the new energy motor is docked with the test equipment, and the motor drive test can be carried out.

[0037] Embodiment 2: This embodiment differs from Embodiment 1 in that:

[0039] The rest is the same as the first embodiment.

[0040] Embodiment 3: This embodiment differs from Embodiment 1 in that:

[0041] In this embodiment, please refer to the attached Figure 5 The transverse clamping plate 7 includes a straight section 71 and an arc section 72. The arc section 72 is connected to the end of the straight section 71 facing away from the calibration plate 5, and the distance between the arc sections 72 of the two transverse clamping plates 7 increases gradually from the connecting end to the opposite end. When placing the new energy motor, the new energy motor first contacts the arc section 72. Under the arc action of the arc section 72, it is easy to push the arc section 72 to drive the two transverse clamping plates 7 to move away from each other, so that the new energy motor can be easily placed between the two transverse clamping plates 7.

[0042] In this embodiment, please refer to the attached Figure 5The fixed end plate 8 is provided with an adjusting bolt 12 for adjusting the elastic force of the preload spring 3. The adjusting bolt 12 is threadedly connected to the fixed end plate 8. The end of the adjusting bolt 12 is connected to a mounting groove 13. One end of the preload spring 3 is mounted in the mounting groove 13. By rotating the adjusting bolt 12, the mounting groove 13 can be driven to translate, that is, the position of the fixed end of the preload spring 3 can be adjusted, so that the elastic force of the working end of the preload spring 3 can be adjusted, so that the elastic force of the preload spring 3 is adjustable, and when the elastic forces of the two preload springs 3 are not equal, they can be adjusted to be equal.

[0043] The rest is the same as the first embodiment.

[0044] Embodiment 4: This embodiment differs from Embodiment 1 in that:

[0045] In this embodiment, please refer to the attached Figure 6 , the transverse clamping plate 7 includes a straight section 71 and an arc section 72, the arc section 72 is connected to the top of the straight section 71, and the spacing between the arc sections 72 of the two transverse clamping plates 7 increases gradually from the connecting end to the opposite end. In the initial state, the position of the transverse clamping plate 7 is relatively low, which is convenient for directly inserting the new energy motor into the calibration hole 51, and then driving the bidirectional screw slider structure 2 to drive the upper clamping plate 1 and the lower clamping plate 4 to move toward each other. In this process, the arc section 72 first contacts the new energy motor, and then as the lower clamping plate 4 continues to rise, the arc effect of the arc section 72 is cooperated to make the two transverse clamping plates 7 automatically open, which is convenient for the new energy motor to enter between the two transverse clamping plates 7, until the upper clamping plate 1 and the lower clamping plate 4 clamp the new energy motor, that is, it can achieve vertical centering clamping while achieving horizontal centering clamping.
