The height adjustment member 220 is used to adjust the height of the first detection member 230, and the first detection member 230 is used to detect the axial displacement of the output end of the motor 300. In this embodiment, the height of the first detection member 230 is adjusted by the height adjustment member 220, so that the first detection member 230 can correspond to the output end of the motor 300, so that the present application can detect motors 300 of different specifications well when detecting them, which can effectively improve the flexibility. In this embodiment, there is no limitation on the height adjustment member 220, which may be a linear drive structure or other structures. When a linear drive structure is adopted, it may be driven by a linear motor 300 or a cylinder.

In this embodiment, when the motor 300 is detected, the vibration generated by the motor 300 at different speeds and the axial displacement of the output end of the motor 300 can be tested by currents of different sizes, so as to further improve the performance of the present application. At the same time, for the speed regulation component, automatic adjustment can be used for adjustment. Specifically, the current gradually increases within three minutes, and the synchronization of the gradual increase in current can be achieved by gradually changing the resistance. For the automatic change of resistance, a linear drive structure can be used to gradually adjust the resistance of the sliding rheostat within a preset time. Other structures can also be used, which are not limited here.

[0038] In one embodiment, reference Figure 1 , Figure 2 , the automatic detection structure of the permanent magnet synchronous motor 300 also includes a second detection member 250, and the second detection member 250 is used to detect the vibration amplitude of the motor 300. In this embodiment, the second detection member 250 can use a vibration sensor, and a micrometer can also be used to test the vibration amplitude of the motor 300.

[0040] In one embodiment, reference Figure 1 , Figure 2 , Figure 3 The mounting seat 221 is provided with a mounting groove 224, and the mounting groove 224 is used for the first detection member 230 to be installed. The mounting seat 221 is also provided with a through hole 225 on the outside, and the through hole 225 is connected to the mounting groove 224, and the through hole 225 is used for the connection line to pass through. In this embodiment, under the action of the mounting groove 224, the first detection members 230 of different specifications can be conveniently installed in the mounting seat 221, and at the same time, under the action of the through hole 225, the connection line in the first detection member 230 can be conveniently passed through the mounting seat 221.

[0041] In one embodiment, reference Figure 3 In order to further ensure the accuracy of the measurement, the first detection member 230 can also be fixed in the installation groove 224. The specific fixing method can adopt the following structure: the height adjustment member 220 also includes a limiting member 240, and the limiting member 240 is used to fix the first detection member 230 in the installation groove 224.

[0042] In one embodiment, reference Figure 3In order to reduce the production cost and operation difficulty of the limiting member 240, the limiting member 240 can adopt the following structure, wherein the limiting member 240 includes an adjusting bolt 241 and a pressing plate 242 connected to each other, wherein the pressing plate 242 is located in the mounting groove 224, and the end of the adjusting bolt 241 not connected to the pressing plate 242 passes through the mounting seat 221, and the adjusting bolt 241 is threadedly connected to the mounting seat 221. In this embodiment, after the first detection member 230 is installed in the mounting groove 224, the pressing plate 242 is moved toward the first detection member 230 by rotating the adjusting bolt 241, and the first detection member 230 is fixed in the mounting groove 224 by pressing. In other embodiments, the limiting member 240 can also adopt a fixing bolt (not shown), and the first detection member 230 is fixed in the mounting groove 224 by the fixing bolt, wherein the fixing bolt is installed from one end of the mounting seat 221 having a through hole 225, and the first detection member 230 can be prevented from being squeezed by the fixing bolt.

[0043] In one embodiment, reference Figure 1 , Figure 2 In order to further reduce the production cost of the present application and the difficulty of operating the equipment, the positioning member 222 can adopt the following structure, the positioning member 222 is configured as a positioning bolt, the mounting frame 210 is provided with a guide hole 212, the guide hole 212 is communicated with the guide groove 211, one end of the positioning bolt is threadedly connected to the mounting seat 221, and the other end passes through the guide hole 212 and is located outside the mounting seat 221. When the mounting seat 221 needs to be positioned at a specified position, the positioning bolt needs to be loosened first, at this time, the mounting seat 221 can be made to slide in the mounting frame 210, and when it slides to the specified position, the positioning bolt is tightened, and the mounting seat 221 is positioned at the specified position under the action of friction, and its operation is very convenient.

[0044] In one embodiment, reference Figure 3 The first detection member 230 is configured as a displacement sensor. In this embodiment, the displacement sensor is used to detect the axial displacement of the output end of the motor 300. The cost of the structure is low and the installation of the equipment is more convenient.

[0045] In one embodiment, reference Figure 1 , Figure 2The base body 100 includes a first mounting plate 110, a second mounting plate 120, a connecting plate 140 and a reinforcing plate 130, wherein the base body 100 is installed in the work station through the second mounting plate 120, and specifically, the second mounting plate 120 is installed in the work station by bolt locking. The connecting plate 140 connects the first mounting plate 110 and the second mounting plate 120, the first mounting plate 110 is used to install the power motor 300, the reinforcing plate 130 connects the first mounting plate 110, the second mounting plate 120 and the connecting plate 140, in this embodiment, the first mounting plate 110 is provided with an installation area for installing the power motor 300, wherein the motor 300 is fixed to the first mounting plate 110 by bolts and nuts, and at the same time in this embodiment, under the action of the connecting plate 140, a certain distance can be provided between the first mounting plate 110 and the second mounting plate 120, and it is precisely because of the effect of this distance that the vibration generated when the motor 300 rotates at full load can be less transmitted to the second mounting plate 120, thereby avoiding the second mounting plate 120 from being vibrated, which causes the seat body 100 to vibrate as a whole.

[0046] In one embodiment, the seat body 100 is made of cast iron and is integrally formed. By using cast iron and forming the seat body 100 in an integral manner, the seat body 100 has a heavier weight during use. In this way, the seat body 100 can have better shock absorption and vibration reduction functions, and can further absorb the vibration generated by the motor 300 under full load operation, thereby preventing the seat body 100 from shaking significantly. If the seat body 100 shakes significantly during the detection process, it will affect the detection accuracy and thus affect the detection results.

[0047] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
