[0003] In the prior art, motor testing equipment usually includes a test equipment body and a test bench for carrying the motor. During testing, the staff needs to install and adjust the horizontal position of the motor so that the output shaft of the motor can extend into the coupling at the test end of the test equipment body.

[0026] Embodiment 1

[0027] like Figure 1 As shown, the adjustment device is used to adjust the posture and / or position of the output shaft of the motor 1. The adjustment device is arranged on the test bench. The adjustment device includes an adjustment body, a centering detection component and a control module. The adjustment body has a mounting surface 21. The mounting surface 21 is used to mount the motor 1. The inclination angle and / or height of the mounting surface 21 can be adjusted. The centering detection component 30 includes a first centering detection device and a second centering detection device. The first centering detection device is arranged on the motor 1, and the second centering detection device is arranged on the test equipment body to obtain the coaxiality deviation value between the output shaft and the central axis of the test end of the test equipment body according to the detection value between the first centering detection device and the second centering detection device. The control module is connected to both the adjustment body and the centering detection component 30. The control module adjusts the inclination angle and / or height of the mounting surface 21 according to the coaxiality deviation value to adjust the posture and / or position of the output shaft, thereby adjusting the coaxiality between the output shaft and the central axis of the test end.

[0028] The technical solution of this embodiment is applied, the adjustment device is used to adjust the posture and / or position of the output shaft of the motor 1 and is arranged on the test bench, the adjustment body of the adjustment device has a mounting surface 21, the mounting surface 21 is used to mount the motor 1, the inclination angle and / or height of the mounting surface 21 can be adjusted, the centering detection component 30 includes a first centering detection device and a second centering detection device, the first centering detection device is arranged on the motor 1, and the second centering detection device is arranged on the test equipment body, so as to obtain the coaxiality deviation value between the output shaft and the central axis of the test end of the test equipment body according to the detection value between the first centering detection device and the second centering detection device, the control module is connected to both the adjustment body and the centering detection component, and the control module adjusts the inclination angle and / or height of the mounting surface 21 according to the coaxiality deviation value to adjust the posture and / or position of the output shaft, thereby adjusting the coaxiality between the output shaft and the central axis of the test end. In this way, the adjustment device can spontaneously adjust the height or inclination angle of the mounting surface 21 according to the detection value between the first centering detection device and the second centering detection device, and the motor 1 installed on the mounting surface 21 can move synchronously with the mounting surface 21, thereby realizing automatic adjustment of the posture and position of the output shaft of the motor 1, thereby ensuring that the output shaft of the motor 1 has a high coaxiality with the test end of the test equipment body, reducing the influence of the coaxiality error on the test results of the test equipment body, thereby solving the problem of low accuracy of the test results of the motor testing equipment in the prior art and improving the degree of automation of the motor testing equipment.

[0029] Specifically, the adjustment device in this embodiment can ensure that there is a high coaxiality between the output shaft of the motor 1 and the test end of the test equipment body, thereby avoiding the bearing damage problem caused by large coaxiality deviation during the test of the motor 1 with a higher speed, thereby improving the test reliability of the motor test equipment.

[0030] Optionally, the adjustment body includes a support structure 20, the support structure 20 has a mounting surface 21, and the height of the support structure 20 is adjustable. There are multiple support structures 20, and the control module is connected to each support structure 20. The control module adjusts the height of each mounting surface 21 by adjusting the height of each support structure 20. In this way, since the height of the support structure 20 is adjustable, the control module can adjust the height of the mounting surface 21 set on the support structure 20 by adjusting the height of the support structure 20, and then adjust the posture or position of the output shaft of the motor 1 installed on the mounting surface 21. At the same time, since there are multiple support structures 20, the control module can adjust the height difference between the mounting surfaces 21 of each support structure 20 to adjust the output shaft and posture of the motor 1 at the same time, thereby ensuring that the output shaft of the motor 1 has a high coaxiality with the test end of the test equipment body, thereby improving the adjustment reliability of the adjustment device.

[0031] In this embodiment, there are four supporting structures 20 to form four mounting surfaces 21. The control module can synchronously adjust the heights of the four mounting surfaces 21 to adjust the height of the motor 1; the control module can also adjust the height difference between the four mounting surfaces to simultaneously adjust the posture and height of the motor 1.

[0032] It should be noted that the number of the supporting structures 20 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the supporting structures 20 is two, three, five, six, seven, eight, or more.

[0033] like Figure 1 As shown, the support structure 20 is a drive cylinder and includes a drive rod 22 and a cylinder body 23. The control module adjusts the height of the support structure 20 by adjusting the extension length of the drive rod 22. The adjustment device also includes a displacement sensor 40, which is arranged on the cylinder body 23. The displacement sensor 40 is arranged relative to at least part of the drive rod 22 to detect the extension length of the drive rod 22. Among them, the control module is also connected to the displacement sensor 40, and the control module corrects the extension length of the drive rod 22 according to the detection value of the displacement sensor 40. In this way, the above-mentioned setting makes the height adjustment method of the support structure 20 simpler, that is, the height of the support structure 20 can be adjusted by only controlling the extension or retraction of the drive rod 22, which not only reduces the difficulty of adjusting the height of the support structure 20, but also makes the structure of the support structure 20 simpler, easy to process and realize; on the other hand, by setting the displacement sensor 40 to correct and adjust the extension length of the drive rod 22, the accuracy of the height adjustment of the support structure 20 can be ensured, thereby improving the adjustment reliability of the adjustment device.

[0034] Specifically, after the control module obtains the coaxiality deviation value between the output shaft of the motor 1 and the central axis of the test end of the test equipment body, the control module can calculate the height adjustment amount of each support structure 20 according to the coaxiality deviation value, and control the driving rod 22 to extend or retract for adjustment; and in the adjustment process, the displacement sensor 40 on each support structure 20 will detect the extension or retraction amount of the driving rod 22 in real time. If the detection value of the displacement sensor 40 is inconsistent with the height adjustment amount, the control module will further adjust the height of the support structure 20 according to the difference between the detection value of the displacement sensor 40 and the height adjustment amount to ensure that the support structure 20 has a high height adjustment accuracy.

[0035] Optionally, the adjustment body also includes a mounting structure 10, which is arranged on the mounting surface 21. There are multiple mounting structures 10, and the multiple mounting structures 10 are arranged one-to-one with the multiple supporting structures 20. The motor installation space is formed around the multiple mounting structures 10. Each supporting structure 20 can be movably arranged on the test bench. The supporting structure 20 drives the corresponding mounting structure 10 to move to adjust the size of the motor installation space. In this way, the above-mentioned setting enables the motor 1 to be installed on the mounting surface 21 through the mounting structure 10 on the one hand; on the other hand, it makes the number of supporting structures 20 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff. At the same time, since each supporting structure 20 can be movably arranged on the test bench, the staff can operate the supporting structure 20 to move to adjust the size of the motor installation space, so that the adjustment device can adjust the motors 1 of different specifications and sizes, thereby improving the versatility of the adjustment device.

[0036] In this embodiment, there are four mounting structures 10 , and the four mounting structures 10 and the four supporting structures 20 are arranged in a one-to-one correspondence.

[0037] It should be noted that the number of the mounting structures 10 is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the number of the mounting structures 10 is two, three, five, six, seven, eight, or more.

[0038] like Figure 1 As shown, the adjustment device also includes a first guide rail assembly 50, and the first guide rail assembly 50 includes a first guide rail 51 and a first slider 52, and the first slider 52 can slide along the extension direction of the first guide rail 51. The support structure 20 is arranged on the first slider 52 and moves synchronously with the first slider 52. Among them, the first guide rail 51 extends along the first preset direction, and the first slider 52 drives the mounting structure 10 to move along the first guide rail 51 to adjust the size of the motor installation space in the first preset direction. In this way, the above arrangement can improve the sliding stability of the support structure 20 along the first preset direction while realizing the sliding of the support structure 20 along the first preset direction through the first guide rail assembly 50, which not only reduces the difficulty of the staff to operate the support structure 20 to slide, but also improves the position adjustment accuracy of the support structure 20.

[0039] In this embodiment, the first guide rail assembly 50 is a guide rail assembly with a self-locking function. After the staff adjusts the support structure 20 to a preset position, the guide rail assembly can be operated to self-lock to achieve the fixation of the support structure 20.

[0040] like Figure 1As shown, the adjustment device also includes a second guide rail assembly 60, which includes a second guide rail 61 and a second slider 62. The second slider 62 can slide along the extension direction of the second guide rail 61, and the first guide rail 51 is arranged on the second slider 62 and moves synchronously with the second slider 62. Among them, the second guide rail 61 is arranged on the test bench and extends along the second preset direction. The second slider 62 drives the support structure 20 to move by driving the first guide rail 51 to move, thereby adjusting the size of the motor installation space in the second preset direction. The first preset direction and the second preset direction are arranged at a first angle. In this way, the second guide rail assembly 60 can improve the sliding stability of the first guide rail 51 while driving the support structure 20 to slide along the second preset direction through the first guide rail 51, thereby improving the sliding stability of the support structure 20 along the second preset direction. At the same time, on the one hand, the above-mentioned setting enables the dimensions of the motor installation space in the first preset direction and the second preset direction to be adjusted, thereby increasing the size adjustment range of the motor installation space and further improving the versatility of the adjustment device; on the other hand, it makes the angle setting between the first preset direction and the second preset direction more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0041] In this embodiment, the second guide rail assembly 60 is a guide rail assembly with a self-locking function. After the staff adjusts the support structure 20 to a preset position, the guide rail assembly can be operated to self-lock to achieve fixation of the support structure 20.

[0042] In this embodiment, the first preset direction and the second preset direction are arranged at 90 degrees, the first preset direction is actually the width direction of the test bench, and the second preset direction is actually the length direction of the test bench. In this way, the staff can adjust the length and width dimensions of the motor installation space to match the size of the motor 1.

[0043] It should be noted that the value of the first angle between the first preset direction and the second preset direction is not limited thereto, and can be adjusted according to working conditions and usage requirements. Optionally, the value of the first angle between the first preset direction and the second preset direction is 60°, or 75°, or 105°, or 120°.

[0044] like Figure 1As shown, the mounting structure 10 includes a connecting plate 111 and a mounting plate 112, wherein the mounting plate 112 is arranged on the connecting plate 111, and the motor 1 is mounted on the mounting plate 112 by passing fasteners through the mounting plate 112 and the motor 1, and the plate surface of the connecting plate 111 away from the mounting plate 112 is used to connect with the mounting surface 21, and the connecting plate 111 and the mounting plate 112 are arranged at a second angle. Among them, the mounting plates 112 of each mounting structure 10 are surrounded to form a motor mounting space. In this way, the mounting structure 10 can not only be connected to the mounting surface 21 through the connecting plate 111, but also be connected to the motor 1 through the mounting plate 112, thereby realizing the installation function of the mounting structure 10. At the same time, the above-mentioned setting makes the angle between the connecting plate 111 and the mounting plate 112 more flexible and diverse, so as to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0045] In this embodiment, the connection plate 111 and the mounting plate 112 are arranged at 90 degrees, so that the posture of the mounting plate 112 can match the structure of the motor 1, thereby ensuring a high connection strength between the motor and the mounting plate 112.

[0046] It should be noted that the value of the second angle between the connecting plate 111 and the mounting plate 112 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the value of the second angle between the connecting plate 111 and the mounting plate 112 is 60°, 75°, 105°, or 120°.

[0047] In this embodiment, a reinforcing rib 113 is further provided between the connecting plate 111 and the mounting plate 112 , and the reinforcing rib 113 is used to improve the connection strength between the connecting plate 111 and the mounting plate 112 .

[0048] like Figure 1As shown, the driving rod 22 includes a rod body 221 and a plate-like structure 222, the rod body 221 is drivingly connected to the cylinder body 23, the plate-like structure 222 is arranged on one end of the rod body 221 away from the cylinder body 23, the plate surface of the plate-like structure 222 away from the cylinder body 23 is the mounting surface 21, the mounting surface 21 is provided with a positioning recess, and the connecting plate 111 is provided with a positioning hole. The adjustment device also includes a columnar positioning structure 70, the columnar positioning structure 70 is penetrated in the positioning hole and the positioning recess, so as to position the mounting structure 10; and / or, a limiting structure 80, having at least two limiting arms 81 arranged oppositely, at least two limiting arms 81 are arranged oppositely to surround and form a limiting space, at least part of the plate-like structure 222 and at least part of the connecting plate 111 are located in the limiting space, at least one limiting arm 81 is limited by the plate-like structure 222, and at least another limiting arm 81 is limited by the connecting plate 111. In this way, by fixing the mounting structure 10 with the columnar positioning structure 70 and the limiting structure 80, the disassembly and assembly efficiency of the mounting structure 10 by the staff can be greatly improved. Compared with conventional fastener fixing, the staff only needs to plug and unplug the columnar positioning structure 70 and install and remove the limiting structure 80 to complete the disassembly and assembly of the mounting structure 10. At the same time, the columnar positioning structure 70 can limit the degree of freedom of the mounting structure 10 in the horizontal direction, and the limiting structure 80 can limit the degree of freedom of the mounting structure 10 in the vertical direction, thereby improving the installation stability of the mounting structure 10.

[0049] Specifically, since the sizes and shapes of motors 1 of different specifications are quite different, the staff often need to set the mounting structures 10 of different structures according to the actual structure of the motor 1, and install the mounting structures 10 of different structures on the support structure 20 when testing the motor 1. By setting the columnar positioning structure 70 and the limiting structure 80 to fix the mounting structure 10, the disassembly and assembly efficiency of the staff can be greatly improved and the operation difficulty of the staff can be reduced.

[0050] Optionally, the columnar positioning structure 70 is a positioning pin.

Wherein, the control module is connected to the test equipment body, and during the test of the test equipment body, when the detection value of the centering detection component 30 is greater than or equal to the preset value, the control module controls the test equipment body to stop running and controls the alarm device to send an alarm signal. In this way, the above setting can avoid the motor 1 from being tested under the condition of large coaxiality deviation, so as to avoid the bearing of the motor 1 from being damaged during the test, thereby extending the service life of the motor 1 and improving the adjustment reliability of the adjustment device; on the other hand, by sending an alarm signal through the alarm device, it can ensure that the staff can promptly and quickly find that the adjustment device has a problem, so as to facilitate the staff to timely repair the adjustment device. At the same time, the above setting makes the structure of the alarm device more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0053] Optionally, the alarm device is a buzzer, which can alert the staff by emitting a sound signal.

[0054] Optionally, the alarm device is an LED lamp, which emits a light signal to alert the staff.

[0055] Specifically, when the detection value of the centering detection component 30 is greater than or equal to a preset value, after the control module controls the test equipment body to stop running, the control module can also control the support structure 20 to run, so as to readjust the coaxiality between the output shaft of the motor 1 and the center axis of the test end of the test equipment body.
