In this embodiment, the two transfer modes of the pair of support seats 57, namely, the up-down movement and the rotation along the axis extending in the up-down direction, are realized by simply building three beams.

[0065] In addition, in order to make the support of the motor to be tested and the test motor 47 more stable, in this embodiment, it can be seen that Figure 4 and Figure 5, the supporting mechanism 42 also includes a quick-change clamping mechanism 43, and the quick-change clamping mechanism 43 includes a mounting plate 62 and a clamping mechanism. The mounting plate 62 can be detachably mounted on the supporting seat 57. The test motor 47 is arranged on the mounting plate 62, and a avoidance hole 621 is provided on the mounting plate 62 for the main shaft of the motor to be tested to pass through and be connected with the main shaft of the test motor 47 for positioning and driving. There are various detachable connection methods, not limited to threaded connection, snap-fit ​​connection, etc. Through the detachable connection, it is convenient to remove and replace the mounting plate 62 when adapting to different motors to be tested.

A clamping groove is provided on the opposite end surfaces of the two connecting plates 49, so that the mounting plate 62 can be detachably installed thereon. The installation method is obviously not limited to this. For example, it can also be a snap-fit ​​connection. Then, the side wall thickness of the mounting plate 62 is small, and a clamping groove is opened on the connecting plate 49 correspondingly. The processing technology is simple, and it is convenient for processing and production without the need for other parts.

[0067] Furthermore, in order to make the mounting plate 62 and the counter bracket 57 more secure and easier to assemble and disassemble when installed together, a connecting hole is provided on the mounting plate 62, and a knob plunger 50 is provided in the connecting hole for fixing the mounting plate 62 on the connecting plate 49.

[0068] In addition, in order to accurately align the test motor 47 with the motor to be tested, in this embodiment, a guide positioning column 622 is provided on the mounting plate 62 to cooperate with the positioning hole provided on the motor to be tested, so that the motor to be tested and the mounting plate 62 are initially positioned, which makes it more convenient to align the test motor 47 with the motor to be tested later.

[0069] In addition, in this embodiment, the mounting plate 62 includes a plate body and a buffer pad 61 disposed on the side of the plate body facing away from the test motor 47. When the motor to be tested passes through the mounting plate 62 and is supported against the test motor 47, the front end of the motor to be tested will be close to one side of the mounting plate 62. In this embodiment, a buffer pad 61 is disposed on this side of the mounting plate 62, and the motor to be tested is close to the buffer pad 61 to avoid the risk of collision and damage between the motor to be tested and the mounting plate 62.

[0070] In addition, in this embodiment, the clamping portion includes the end of a telescopic rod of a clamping cylinder 58, and the clamping cylinder 58 is provided on the mounting plate 62, wherein the clamping cylinder 58 is arranged on the mounting plate 62, wherein the clamping cylinder 58 is a mechanical device for clamping a workpiece, and its main principle is to clamp the workpiece through air pressure, thereby completing various processing and handling tasks.

[0071] See also Figures 4 to 6 In this embodiment, in order to adapt to different motors to be tested, a plurality of mounting plates 62 are provided, and at least some of the mounting plates 62 have different sizes; a connecting block is provided on the main shaft of the test motor 47, and a plurality of the connecting blocks are provided, and at least some of the connecting blocks have different sizes; the mounting plates 62 correspondingly connected to the same test motor 47 form a connecting group with the connecting block, and different mounting plates 62 are selected and combined with the corresponding connecting blocks to form different connecting groups for installation of motors to be tested of different sizes.

[0072] In addition, in this embodiment, the motor to be tested is tested, and the motor testing device 100 further includes a circuit board, two handles 44 and two control buttons, wherein the two handles 44 are disposed on the support seat 57; two control buttons are disposed on the two handles 44, wherein one control button is electrically connected to the test motor 47 and the circuit board, and the other control button is electrically connected to the control element on the air path of the clamping cylinder 58 and the circuit board. In this way, the operator can make the test motor 47 test the motor to be tested by pressing the control button.

[0073] The specific implementation of the motor testing device 100 includes the following steps:

[0074] Step 1, make the test motor 47 and the motor under test to be supported. When the motor product under test is in the test station, the support handle 44 is manually held with both hands, and the front-to-back and left-to-right direction transfer is realized by the transfer mechanism 1, and the up-down direction transfer is realized by the lifting and rotating mechanism 2. The lifting and rotating mechanism 2 realizes the rotation in the axis direction extending in the up-down direction by rotating the connecting block 5, so that the support test mechanism 3 is moved to the front end of the test station, and the preliminary positioning is realized by manually aligning the tooling guide column 59 with the positioning hole of the motor product under test, so that the output shaft of the motor product under test is connected with the quick-change test connecting block 53, and the front end face of the motor product under test is close to the support buffer pad 61.

[0075] Step 2, clamp and position the motor under test and conduct a test. Manually control the button above a support handle 44 to control the clamping cylinder 58 to clamp the motor product under test to prevent the support test mechanism 3 from being separated from the motor product under test during the test. The in-place detection sensor 51 detects that the motor product under test is in place, and manually control the button above another support handle 44 to start the test; after the test is completed, manually control the button above a support handle 44 to control the clamping cylinder 58 to release the motor product under test, and hold the support handle 44 with both hands to return the support test mechanism 3 to the initial position.

[0076] Step 3, when the model of the motor under test needs to be changed, the support mechanism 42 needs to be replaced. Manually pull up the knob plunger 50 of the quick-change mounting plate 49 in the left and right directions respectively, then separate the mounting plate 62 upward from the mounting slot of the quick-change mounting plate 49, and manually force the quick-change test connection block 53 forward to separate the test fixed connection block 55. Since the quick-change test connection block 53 is connected to the test fixed connection block 55 through the spring plunger 54, it is very convenient to realize the plug-in and pull-out quick change in the front and back directions, and replace the corresponding mounting plate 62 and quick-change test connection block 53 according to the tooling corresponding to the product model of the motor under test.

[0077] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
