[0002] When a motor is subjected to factory inspection, it needs to be tested including no-load running-in test, gear shifting test, hydraulic oil pump working condition test, etc. Among them, the parameters to be tested in the no-load running-in test include recording engine speed, generator speed, no-load voltage, excitation current, temperature rise record, etc.

[0003] For example, the Chinese patent "CN205898446U" discloses an "automatic control no-load running-in test device". By setting more than two test ends, the device realizes the connection between the motor to be tested and the test circuit, thus realizing the control of the test circuit over multiple motors to be tested, and finally improving the speed of performance testing of a batch of motors to be tested, meeting the requirements of modern rapid industrial production. However, during the process of motor testing, it is found that due to the torque generated by the rotor during the operation of the motor, the motor cannot be stabilized on the workbench surface. Therefore, each motor needs to be fixed on the bearing plate by screws, and the screws need to be installed and removed before and after each test, resulting in time and labor consumption during batch testing of motors. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a no-load running-in test device, which solves the problem that the method of fixing the motor by screws for testing in the prior art is time-consuming and laborious.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a no-load running-in test device for installing a motor 2, comprising:

[0024] The running-in table 1 is provided with a number of bearing plates 3 for mounting the motor 2 along its length;

[0025] The fixing assembly includes two limit plates 5 mirror-mounted on the supporting plate 3 and an adjusting member rotatably arranged on the supporting plate 3. The adjusting member is connected to the two limit plates 5 and is used to move the two limit plates 5 closer to or farther away from each other to limit the motor 2 or release the limit.

[0026] In the embodiment of the present invention, the supporting plate 3 is arranged along the length direction of the running-in table 1, which can facilitate the installation of several motors 2 for simultaneous testing, and each supporting plate 3 is provided with a fixing assembly for fixing the motor 2. Under the setting of the fixing assembly, after the motor 2 is installed on the supporting plate 3, the two limiting plates 5 can be driven to approach each other by the adjusting member and the cooperation of the two limiting plates 5, and respectively abut on both sides of the base of the motor 2, so as to clamp the motor 2 and achieve rapid positioning. After the motor 2 on the supporting plate 3 is tested, the two limiting plates 5 are again driven away from each other by the adjusting member, so that the limiting plates 5 are separated from the sides of the base of the motor 2, and the limit of the motor 2 can be quickly released. After the motor 2 is taken out, another motor 2 to be tested can be installed.

[0027] Compared with traditional screw fixation, there is no need to frequently use tools to install and remove screws, and the motor 2 can be quickly fixed to the supporting plate 3, which greatly reduces the preparation time and labor costs before and after the test. It can also avoid the problem that manual tightening of the screws may cause damage to the motor 2 or the supporting plate 3 due to improper force. At the same time, by adjusting the distance between the two limit plates 5, motors 2 with different base sizes can also be fixed, which improves versatility.

[0028] Based on the above scheme, if Figure 2 and Figure 3 As shown, the adjusting member includes an adjusting rod 4 rotatably arranged on the supporting plate 3 and two driving blocks 503 slidably arranged on the supporting plate 3. The two driving blocks 503 are respectively connected to the two limit plates 5. Both ends of the adjusting rod 4 are provided with a threaded section 401, and the two driving blocks 503 are respectively threadedly connected to the two threaded sections 401.

[0029] Specifically, when adjusting the two limit plates 5 through the adjusting member, by rotating the adjusting rod 4, the adjusting rod 4 rotates on its own axis on the bearing plate 3, thereby driving the two threaded sections 401 on the adjusting rod 4 to rotate on their own axes. Since the helix directions of the two threaded sections 401 are opposite, when the two threaded sections 401 rotate forward and backward, the two limit plates 5 threadedly connected thereto can be driven to approach or move away from each other.

[0030] Specifically, as Figure 3 shown, the adjusting member further includes a driving rod 6 rotatably provided on the running-in table 1. The adjusting rod 4 is provided with a through hole penetrating through its interior, and the adjusting rod 4 is inserted through the through holes of the respective adjusting rods 4; mounting seats are provided on both sides of the running-in table 1, and the driving rod 6 is mounted between the two mounting seats. In order to facilitate the synchronous fixing operation of the motors 2 for all the bearing plates 3, the driving rod 6 is inserted through the adjusting rods 4 on each bearing plate 3, that is, each driving rod 6 is sleeved on the adjusting rod 4. To ensure stability, the driving rod 6 and the adjusting rod 4 are in interference fit. In the assembly with each adjusting rod 4, the driving rod 6 can be divided into several segments and finally welded into shape. When the driving rod 6 is rotated, all the adjusting rods 4 can be driven to rotate, thereby adjusting the limit plates 5 on each bearing plate 3. The batch installation of the motors 2 can be completed with one operation, which saves more time and labor. Moreover, a handwheel 602 is provided on the side surface of the running-in table 1, and one end of the driving rod 6 is fixedly connected to the handwheel 602. The handwheel 602 provides a larger contact surface, enabling the operator to more easily apply force to rotate the driving rod 6, especially in the case where a large torque is required, reducing the labor intensity.

[0031] To facilitate the installation of the driving rod 6 and the adjusting rod 4, as Figure 3 shown, the driving rod 6 is fixedly provided with a clamping block 601, and the clamping block 601 is clamped in the through hole of the adjusting rod 4; on the premise that the two are not in interference fit, the circumferential limit of the driving rod 6 can be achieved through the setting of the clamping block 601 to ensure the stability of the connection between the two.

[0032] Specifically, as Figure 1 shown, limit blocks 402 are fixedly provided at both ends of the adjusting rod 4, and both limit blocks 402 are in contact with the side surface of the bearing plate 3, which can ensure that the adjusting rod 4 does not move axially and ensure that the two limit blocks 402 are always centered for adjustment.

[0033] Specifically, as Figure 3As shown, a rubber layer 501 is provided on the inner side of the limit plate 5. The rubber layer 501 abuts against the motor 2. The rubber layer 501 has a certain coefficient of friction, which can effectively prevent the motor 2 from sliding during the test, ensuring that the motor 2 is firmly fixed on the bearing plate 3. Moreover, the rubber layer 501 can be slightly deformed according to the shape of the motor 2 to better fit the surface of the motor 2, providing a more secure fixing effect. Furthermore, the rubber layer 501 can prevent the surface of the limit plate 5 from directly contacting the motor 2, thereby reducing the wear of the limit plate 5.

[0034] Specifically, as Figure 1 shown, limit protrusions 502 are provided at both ends of the limit plate 5 to form a limit space for limiting the motor 2. Even if the motor 2 undergoes a certain displacement, the limit space formed by the limit protrusions 502 can surround the motor 2, effectively preventing the motor 2 from separating from the bearing plate 3 during the test and ensuring the stability of the motor 2 during testing.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
