[0031] Figure 1 A schematic structural diagram of a drive motor vibration test fixture 100 provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, an embodiment of the present application provides a drive motor vibration test fixture 100, comprising a first mounting seat 10 and a second mounting seat 20. The first mounting seat 10 is used to fix the non-driving end of the drive motor, and the second mounting seat 20 is used to fix the driving end of the drive motor. When performing a drive motor vibration test, the first mounting seat 10 and the second mounting seat 20 are used to fix the drive motor to be tested on the vibration table of the motor vibration test bench.

[0032] The first mounting seat 10 includes a first mounting seat body 11 and a mounting plate 12 detachably mounted on the first mounting seat body 11. Figure 2 As shown, the first mounting seat body 11 includes a first bottom plate 111 and a first end plate 112 .

[0033] The first base plate 111 serves as the mounting base for the first end plate 112. The first base plate 111 is provided with a plurality of first fixing holes 1111, which are circular through holes. These first fixing holes 1111 are used to fix the first mounting base body 11 to the vibration table surface via fasteners. The number of first fixing holes 1111 is generally more than 4, and they are arranged in a rectangular array to ensure a stable connection. For example, the number of first fixing holes 1111 is 10, and they are distributed in a 2*5 rectangular array on the first base plate 111. This rectangular array arrangement facilitates adjustment of the position and number of fasteners according to the hole positions on the vibration table surface.

[0034] The first end plate 112 is vertically mounted on the first base plate 111. A mounting plate mounting hole 1121 is provided on the first end plate 112. The mounting plate mounting hole 1121 is a two-step stepped through hole for mounting the mounting plate 12. The mounting plate mounting hole 1121 can be concentrically arranged with the first end plate 112, that is, the center of the mounting plate mounting hole 1121 coincides with the center of the first end plate 112. A plurality of first connecting holes 1122 are evenly distributed along the circumference on the step surface of the mounting plate mounting hole 1121. These first connecting holes 1122 are used to connect the mounting plate 12 through fasteners. Each first connecting hole 1122 is processed with an internal thread or inlaid with a screw sleeve. The number of first connecting holes 1122 can be set as needed. For example, the number of first connecting holes 1122 is 8.

[0035] The first mounting base body 11 also includes two first reinforcing plates 113. Both first reinforcing plates 113 are vertically mounted on the first base plate 111 and are respectively connected to the two side edges of the first end plate 112. The two first reinforcing plates 113 provide structural reinforcement for the first base plate 111 and the first end plate 112. The first reinforcing plates 113 can be shaped like a triangle, a rectangle, or another shape. For example, the first base plate 111 and the first end plate 112 are connected to form an L-shape. The first reinforcing plates 113 are shaped like a right triangle, with two right-angled sides connected to the first base plate 111 and the first end plate 112, respectively.

[0036] Figure 3 and Figure 4 This is a schematic diagram of the structure of a mounting plate 12 provided in an embodiment of the present application at different viewing angles, as shown in FIG. Figure 3 and Figure 4 As shown, combined with Figure 1 and Figure 2The mounting plate 12 is detachably mounted within the mounting plate mounting hole 1121 of the first end plate 112. The shape of the mounting plate 12 matches the shape of the mounting plate mounting hole 1121. Specifically, the outer diameter of the mounting plate 12 matches the diameter of the large hole section of the mounting plate mounting hole 1121. One end surface of the mounting plate 12 includes a boss 121 that cooperates with the small hole section of the mounting plate mounting hole 1121. The diameter of the boss 121 matches the diameter of the small hole section.

[0037] The mounting plate 12 is provided with a plurality of second connection holes 122 corresponding to the plurality of first connection holes 1122. These second connection holes 122 are circular through holes. These circular through holes are evenly distributed along the circumference near the circumferential edge of the mounting plate 12 and are located on the outside of the boss 121. These second connection holes 122 are used to connect to the first end plate 112 via fasteners. The number of second connection holes 122 is consistent with the number of first connection holes 1122. For example, the number of second connection holes 122 is 8. The mounting plate 12 is connected to the plurality of first connection holes 1122 after a plurality of fasteners pass through the plurality of second connection holes 122, thereby achieving installation with the first end plate 112. In addition, when the mounting plate 12 is installed on the first end plate 112, the end face and the other end face of the boss 121 of the mounting plate 12 are respectively flush with the two plate surfaces of the first end plate 112, ensuring a smooth appearance.

[0038] The mounting plate 12 is provided with at least one circle of motor fixing holes, which are used to connect the non-drive end of the drive motor via fasteners. A single circle of motor fixing holes includes a plurality of first motor fixing holes 123 evenly distributed along the circumference of the mounting plate 12. These first motor fixing holes 123 are circular through-holes and are arranged corresponding to the plurality of connection holes on the non-drive end of the drive motor. For example, the non-drive end of the drive motor has eight connection holes, and the mounting plate 12 is provided with a circle of motor fixing holes, which includes the corresponding eight first motor fixing holes 123. Multiple circles of motor fixing holes can be formed on the mounting plate 12, and these multiple circles of motor fixing holes can be used to secure the connection holes of the non-drive end of drive motors of different specifications.

[0039] A first motor fixing groove 124 is provided on the other end face of the mounting plate 12, and the first motor fixing groove 124 is used to embed and install the non-drive end of the drive motor. The shape of the first motor fixing groove 124 is set according to the shape of the non-drive end of the drive motor. For example, the non-drive end of the drive motor is circular, and the shape of the first motor fixing groove 124 is circular. A center hole 125 is also provided at the bottom center of the first motor fixing groove 124, and the center hole 125 is used to embed and install the center protrusion structure of the non-drive end of the drive motor (a bearing is usually provided inside this position). Usually, the central axis of the multiple connection holes on the non-drive end of a conventional drive motor is coaxial with the central axis of the motor shaft, so that the central axis of the first motor fixing groove 124 is coaxial with the central axis of the mounting plate 12, but the central axis of the multiple connection holes on the non-drive end of some drive motors is parallel to the central axis of the motor shaft, so, for example, as Figure 4 As shown, the central axis of the first motor fixing slot 124 can be arranged parallel to the central axis of the mounting plate 12 , and the first motor fixing slot 124 is used for embedding and mounting the non-driving end of the driving motor.

[0040] Figure 5 A structural diagram of a second mounting base 20 provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, the second mounting seat 20 includes a second bottom plate 21 and a second end plate 22 .

[0041] The second base plate 21 serves as the mounting base for the second end plate 22. The second base plate 21 is provided with a plurality of second fixing holes 211, which are slots that penetrate the second base plate 21 and extend in a direction perpendicular to the second end plate 22. These second fixing holes 211 are used to fix the second mounting base 20 on the vibration table through fasteners, and adopt a slotted hole structure, such as a waist hole, to facilitate alignment of the hole positions on the vibration table. In this way, when installing drive motors of different specifications, the second mounting base 20 can be fixed to the vibration table through fasteners, avoiding the situation where the second fixing holes 211 cannot be aligned with the hole positions of the vibration table. The number of second fixing holes 211 is generally more than 4, and they are arranged in a rectangular array to ensure a stable connection. For example, the number of second fixing holes 211 is 6, and they are distributed in a 2*3 rectangular array on the second base plate 21. This rectangular array arrangement structure makes it convenient to adjust the position and number of fasteners according to the hole positions on the vibration table.

[0042] The second end plate 22 is vertically mounted on the second base plate 21. The height of the second end plate 22 corresponds to the height of the central axis of the mounting plate mounting hole 1121 of the first end plate 112. The top of the second end plate 22 is provided with a second motor fixing slot 221 corresponding to the first motor fixing slot 124 of the mounting plate 12. The second motor fixing slot 221 is used to support the central protrusion structure of the driving end of the drive motor (a bearing is usually provided inside this position). For example, the height of the central axis of the mounting plate mounting hole 1121 is half the height of the first end plate 112, and the height of the second end plate 22 is also half the height of the first end plate 112. The second motor fixing slot 221 is located in the middle position of the top of the second end plate 22. The shape of the second motor fixing slot 221 is set according to the shape of the central protrusion structure of the driving end of the drive motor. For example, the central protrusion structure of the driving end is circular, and the shape of the second motor fixing slot 221 is semicircular.

[0043] The second end plate 22 is provided with a plurality of second motor fixing holes 222, which are slot holes that pass through the second end plate 22 and extend in the vertical direction, and these second motor fixing holes 222 are distributed on the circumferential side of the second motor fixing slot 221. The second motor fixing holes 222 adopt a slot hole structure, such as a waist hole, which is convenient for aligning the connection hole positions of the driving ends of driving motors of different specifications. Exemplarily, the lower half of the driving end of the driving motor has three connection holes, and these three connection holes are circumferentially distributed on the circumferential side of the central protruding structure of the driving end. The number of second motor fixing holes 222 is 3, and the three second motor fixing holes 222 are circumferentially distributed on the circumferential side of the second motor fixing slot 221, wherein one second motor fixing hole 222 is located directly below the second motor fixing slot 221, and the other two second motor fixing holes 222 are respectively located on both sides of the second motor fixing slot 221, and the position of the second motor fixing hole 222 on one side is slightly higher than the position of the second motor fixing hole 222 on the other side, which is convenient for adapting to the connection holes of the lower half of the driving end of driving motors of different specifications.

[0044] The second mounting base 20 also includes two second reinforcing plates 23. Both second reinforcing plates 23 are vertically mounted on the second base plate 21 and are connected to the two sides of the second end plate 22. The two second reinforcing plates 23 provide structural reinforcement for the second base plate 21 and the second end plate 22. The second reinforcing plates 23 can be triangular, rectangular, or other shapes. For example, the second base plate 21 and the second end plate 22 are connected to form an L-shape. The second reinforcing plates 23 are shaped like a right triangle, with two right-angled sides connected to the second base plate 21 and the second end plate 22, respectively.

[0045] As an example, the usage process of the drive motor vibration test fixture 100 is: first set the first mounting seat body 11 on the vibration table of the motor vibration test bench, and then pass multiple fasteners through the multiple first fixing holes 1111 of the first base plate 111 and connect them with the corresponding holes on the vibration table to fix the position of the first mounting seat body 11.

[0046] Next, the mounting plate 12 is installed in the mounting plate mounting hole 1121 of the first end plate 112 , and a plurality of fasteners are passed through the plurality of second connection holes 122 and connected to the plurality of first connection holes 1122 to achieve the connection and fixation between the mounting plate 12 and the first end plate 112 .

[0047] Then, the non-driving end of the driving motor to be tested is embedded and installed in the first motor fixing groove 124 of the mounting plate 12, and the central protrusion structure of the non-driving end is embedded and installed in the central hole 125 at the bottom of the first motor fixing groove 124. After passing through the multiple first motor fixing holes 123 of the mounting plate 12, multiple fasteners are connected to the multiple connecting holes on the non-driving end of the driving motor to realize the connection and fixation of the non-driving end of the driving motor and the mounting plate 12.

[0048] Then, the second mounting base 20 is set on the vibration table, and the second motor fixing groove 221 on the top of the second end plate 22 supports the central protrusion structure of the driving end of the driving motor, and a plurality of fasteners are passed through the plurality of second motor fixing holes 222 of the second end plate 22 and connected to the plurality of connection holes in the lower half of the driving end of the driving motor to realize the connection and fixation between the driving end of the driving motor and the second end plate 22.

[0049] Before fixing the second mounting base 20 to the vibration table, you can first check the torque of the fasteners connecting the non-driving end and the driving end of the drive motor to ensure that the tightness of the connection between the drive motor and the first mounting base 10 and the second mounting base 20 meets the requirements of the vibration test.

[0050] Finally, multiple fasteners are inserted through the multiple second fixing holes 211 of the second base plate 21 and connected to the corresponding holes on the vibration table to secure the second mounting base 20 to the vibration table. This completes the installation of the drive motor on the vibration table of the motor vibration test bench, allowing vibration testing of the drive motor to be performed using the motor vibration test bench.

[0051] In summary, the drive motor vibration test fixture 100 provided in the embodiment of the present application fixes the non-drive end of the drive motor through the first mounting seat 10, and fixes the drive end of the drive motor through the second mounting seat 20, wherein the mounting plate 12 of the first mounting seat 10 is detachably mounted on the first mounting seat body 11, and according to the shape, size and connection hole position of the non-drive end of the drive motor to be tested, the mounting plate 12 is provided with a corresponding first motor fixing groove 124 and a motor fixing hole group, the first motor fixing groove 124 is used for embedding and installing the non-drive end of the drive motor, the motor fixing hole group is used for connecting the non-drive end of the drive motor, and a multi-turn motor fixing hole group can be set to fix the non-drive end of drive motors of different specifications. Therefore, the drive motor vibration test fixture 100 can be suitable for the installation of drive motors of different specifications, saving preparation time before the test, reducing the number of tooling production times, and reducing the tooling production cost.

[0052] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the field can easily think of various changes or replacements within the technical scope disclosed in the present application, which should all be included in the scope of protection of the present application.
