[0002] Automotive generators can be divided into DC generators and AC generators. Automotive generators are simple to manufacture, have low production costs, and are reliable in operation, and are widely used in fields such as new energy and the automotive industry. The miniaturization of the volume of automotive generators and the increasing requirements for output power and output performance have made vibration and noise important indicators for judging the quality of motors. During operation, the electromagnetic noise of automotive generators is relatively large, which has become an important factor restricting the development of automotive generators.

Then, move the pallet to one side of the first shaft seat for preparatory work;

[0019] 3. In the present invention, rotate the control panel to make the second lead screw rotate. The rotation of the second lead screw causes the cross bar on the sleeve block to move.

[0034] Specifically, place the generator on the placement table 112, and then rotate the adjusting disc 208. The rotation of the adjusting disc 208 drives the threaded rod 206 to rotate. The threaded rod 206 is threadedly connected to the socket 205, and the bottom end of the socket 205 is fixedly connected to the second toothed plate 203.

The top end of the transmission belt 506 is sleeved on the first pulley 417.

[0038] Specifically, rotate the control disk 403 to make the second lead screw 402 rotate. The rotation of the second lead screw 402 causes the cross bars 405 on the sleeve block 404 to move. The movement of the cross bars 405 drives the second pulley 409 on the installation box 408 to slide on the guide rod 410 through the push plate 406. The movement of the installation box 408 causes the placement plate 412 on the bracket 411 to move downward. Then, sleeve the bottom end of the transmission belt 506 on the generator, and then rotate the control disk 403 in the reverse direction to make the placement plate 412 move upward. The movement of the placement plate 412 causes the transmission belt 506 to squeeze the driven wheel 505, preventing the transmission belt 506 from falling off during the test. The operation of the test device 413 facilitates the test work on the load condition of the generator.

[0039] Working principle of the present invention: Place the generator on the placement table 112, then rotate the adjustment disk 208.

A socket 205 is threadedly connected to the threaded rod 206, and the bottom end of the socket 205 is fixedly connected to the second toothed plate 203. The rotation of the threaded rod 206 drives the second toothed plate 203 on the socket 205 to slide inside the guide rail 204. The movement of the second toothed plate 203 drives the rotating rod 201 on the gear 202 to rotate. The rotation of the rotating rod 201 pushes the push rod 211 downward through the second arm plate 210 on the first arm plate 209. The movement of the push rod 211 pushes the movable plate 214 on the fixed plate 212 to slide on the positioning rod 215 through the elastic force of the first spring 213. The movement of the movable plate 214 pushes the pressing plate 219 to move through the fixed seat 218 on the docking rod 217, thereby facilitating the fixation of the generator on the placement table 112 by the pressing plate 219;

[0040] When moving the support plate 107, first rotate the turntable 311. The rotation of the turntable 311 drives the first lead screw 310 to rotate. A sleeve plate 309 is threadedly connected to the first lead screw 310, and both ends of the sleeve plate 309 are fixedly connected to the mounting plate 308. The rotation of the first lead screw 310 causes the sleeve plate 309 to drive the mounting plate 308 to move. The movement of the mounting plate 308 facilitates the sliding of the sliding column 307 inside the sliding groove 303, thereby facilitating the linkage plate 302 to drive the adjustment plate 305 to move upward, causing the teeth 306 on the bottom surface of the adjustment plate 305 to disengage from the first toothed plate 110, and then moving the support plate 107 to one side of the first shaft seat 104 for preparatory work;

[0041] Rotate the control disk 403 to make the second lead screw 402 rotate. The rotation of the second lead screw 402 causes the cross bar 405 on the sleeve block 404 to move. The movement of the cross bar 405 drives the second pulley 409 on the mounting box 408 to slide on the guide rod 410 through the push plate 406. The movement of the mounting box 408 causes the placement plate 412 on the bracket 411 to move downward. Then, sleuth the bottom end of the transmission belt 506 on the generator, and then rotate the control disk 403 in the reverse direction to make the placement plate 412 move upward. Through the movement of the placement plate 412, the transmission belt 506 squeezes the driven wheel 505, preventing the transmission belt 506 from falling off during the test. Through the operation of the test device 413, it is convenient to test the load condition of the generator.

[0042] The present invention also provides a safe automotive generator load test method, including:

[0043] Place the generator on the placement table 112, and then fix the generator on the placement table 112 through the fastening assembly. A limiting assembly is provided on one side of the support plate 107. Move the position of the support plate 107 through the limiting assembly, and then move the generator to one side of the frame 4. Perform a load test on the generator through the test assembly on the frame 4.
