DETAILED DESCRIPTION

[0016] In order to make the above-mentioned purpose, features and advantages of the motor forward and reverse rotation and current testing device more obvious and easy to understand, the specific embodiments of the motor forward and reverse rotation and current testing device are described in detail below with reference to the drawings.

[0017] As Figure 1 and Figure 2As shown in the figure, the motor forward and reverse rotation and current testing device provided by the embodiment of the application comprises a rack 1, further comprises an oscilloscope 2 arranged on the rack 1, a material placing seat 3 arranged on the rack 1, a pressing mechanism 4 arranged on the rack 1 for pressing the motor 100 on the material placing seat 3, a forward and reverse rotation detection mechanism 5 arranged on the rack 1 for detecting the forward and reverse rotation of the motor 100, the forward and reverse rotation detection mechanism 5 comprises a fixing seat 51 arranged on the rack 1, a rotating assembly 52 arranged on the fixing seat 51 and driven by the motor 100, a magnet 53 arranged on the rotating assembly 52, a first Hall sensor 54 and a second Hall sensor 55 arranged on the rack 1 for sensing the magnet 53, and the first Hall sensor 54 and the second Hall sensor 55 are symmetrical along the rotation axis of the rotating assembly 52.

[0018] In actual use, the motor 100 to be tested is placed on the material placing seat 3, the two terminals of the motor 100 are connected with the power supply, the positive and negative terminals of the oscilloscope 2 are connected with the two terminals of the motor 100 in conduction, and whether the current output pattern of the motor 100 is normal is observed through the oscilloscope 2. After the motor 100 rotates, the rotating assembly 52 is driven to rotate, the magnet 53 is driven to rotate synchronously by the rotating assembly 52, if the two terminals of the motor 100 are installed normally, the motor 100 rotates forward, the first Hall sensor 54 senses the magnet 53 earlier than the second Hall sensor 55, if the two terminals of the motor 100 are installed reversely, the motor 100 rotates reversely, the second Hall sensor 55 senses the magnet 53 earlier than the first Hall sensor 54.

[0019] In the above design, whether the output current of the motor 100 is normal and whether the two terminals of the motor 100 are installed normally can be sensed at the same time. The testing efficiency can be effectively improved and the cost can be saved.

[0020] Specifically, as shown in the figures, Figure 2 and Figure 3 the rotating assembly 52 comprises a camshaft 521, a deep groove ball bearing 522 connected with the camshaft 521, a first column 523 fixedly connected with one end of the camshaft 521 coaxially, a second column 524 fixedly connected with the other end of the camshaft 521 coaxially, and a disc 525 fixedly connected with the second column 524 coaxially, the magnet 53 is arranged on the side of the disc 525 away from the second column 524, the first column 523 is used for connecting with the output port of the motor 100, and the outer ring of the deep groove ball bearing 522 is connected with the fixing seat 51.

[0021] In actual use, the first column 523 extends into the output port of the motor 100 and cooperates with the output port. For example, the output port of the motor 100 is a square slot, and the first column 523 is also square at the end for cooperating with the output port of the motor 100. After the first column 523 extends into the output port of the motor 100, the motor 100 can drive the first column 523 to rotate. The first column 523 drives the camshaft 521 to rotate after rotating, and the second column 524 and the disc 525 are synchronously rotated after the camshaft 521 rotates. The disc 525 drives the magnet 53 to synchronously rotate. If the motor 100 rotates forward, the disc 525 rotates clockwise, and the first Hall sensor 54 senses the existence of the magnet 53 before the second Hall sensor 55. If the motor 100 is reversed, the disc 525 rotates counterclockwise, and the second Hall sensor 55 senses the existence of the magnet 53 before the first Hall sensor 54.

[0022] In the above design, the structure design of the rotating assembly 52 facilitates the cooperation with the motor 100 and the driving of the magnet 53.

[0023] Specifically, as shown in the drawings, the pressing mechanism 4 includes a rotary pressing cylinder 41 vertically fixed on the rack 1 and a pressing head 42 fixed on the output end of the rotary pressing cylinder 41.

[0024] In actual use, after the motor 100 is placed on the discharging seat 3, the rotary pressing cylinder 41 drives the pressing head 42 to rotate to the position and presses the motor 100.

[0025] In the above design, the structure design and specific implementation of the pressing mechanism 4 can effectively realize the fixation of the motor 100 and ensure the stability of the motor 100 during rotation.

[0026] Specifically, as shown in the drawings, the disc 525 is provided with a discharging hole 501 in the axial direction, and the magnet 53 is arranged in the discharging hole 501. Figure 3

[0027] In the above design, the magnet 53 is placed in the discharging hole 501, which facilitates the installation of the magnet 53.

[0028] Specifically, as shown in the drawings, Figure 2 and Figure 3 ​As shown, the first camshaft 521 is provided with a first slot 5211 and a second slot 5212 in the axial direction, and is provided with a first screw hole 5213 communicated with the first slot 5211 and a second screw hole 5214 communicated with the second slot 5212 in the radial direction, one end of the first column 523 is arranged in the first slot 5211, and the other end of the first column 523 is used for connecting with the output port of the motor 100, one end of the second column 524 is arranged in the second slot 5212, and the other end of the second column 524 is used for fixedly connecting with the disc 525. The first column 523 comprises a cylindrical segment matched with the first slot 5211 and a prismatic segment matched with the output port of the motor 100.

[0029] In actual use, the model of the motor 100 can be different, so the output port of the motor 100 can be different. For example, the output port of some motors 100 is triangular, and the output port of some motors 100 is hexagonal. Different first columns 523 are used for matching different motors 100. When it is needed to change the model of the motor 100 to be tested, the original first column 523 is disassembled from the first slot 5211, and a corresponding first column 523 is replaced, and then the first column 523 in the first slot 5211 is locked by screwing through the threaded cooperation with the first screw hole 5213.

[0030] In the above design, the structural design of the first camshaft 521, the first column 523 and the second column 524 facilitates the testing of different motors 100.

[0031] It should be understood that the above description is only a specific embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
