[0003] In the prior art, testing equipment and de-weighting equipment are typically used to test and de-weight rotating workpieces. During operation, the rotating workpiece is first sent to the testing equipment for dynamic balancing testing. The tested rotating workpiece is then sent to the de-weighting equipment for de-weighting. After de-weighting is complete, the rotating workpiece is sent back to the testing equipment for dynamic balancing retesting.

[0040] In this embodiment, the rotating workpiece 100 includes a rotating body and a housing, which is coaxially mounted on the rotating body and rotatably connected to the rotating body. When the two clamping plates 531 are relatively closed, the housing is supported in the first bearing groove 5124, and the upper ends of the two clamping plates 531 are pressed against the housing. The driving assembly 52 drives the rotating body to rotate, forming a first gap 533 between the two clamping plates 531, and the supporting plate 5122 is movably accommodated in the first gap 533.

A first ejection assembly 41 and a second ejection assembly 45 are arranged in the third gap 44. The first ejection assembly 41 is located at the defective station, and the second ejection assembly 45 is located at the loading and unloading stations.

[0050] The first ejecting assembly 41 includes a first ejecting rack 411 that can be lifted and lowered, and an eighth driving member 412 for driving the first ejecting rack 411 to be lifted and lowered, the eighth driving member 412 is a cylinder, and the first ejecting rack 411 is used to lift and collect defective products during its lifting process; the second ejecting assembly 45 includes a second ejecting rack 451 that can be lifted and lowered, and a tenth driving member 452 for driving the second ejecting rack 451 to be lifted and lowered, the tenth driving member 452 is a cylinder, and the first ejecting rack 411 is used to lift the rotating workpiece 100 upward when loading, so as to facilitate the transportation of the conveying mechanism 2, or to receive the rotating workpiece 100 when unloading and drive the rotating workpiece 100 to descend to the conveying mechanism 4.

[0051] Combine Figure 4 As shown, a collecting assembly 42 is provided above the first top material assembly 41, and the collecting assembly 42 includes a collecting seat 421, a first conveyor belt module 422 provided on the collecting seat 421, and a material guiding module 423. The first conveyor belt module 422 is a belt conveyor. The conveying direction of the first conveyor belt module 422 is the same as the conveying direction of the conveying assembly. The front end of the first conveyor belt module 422 is located directly above the first top material assembly 41. A plurality of first stoppers 424 are provided on the belt of the first conveyor belt module 422 along its conveying direction at intervals. The material guiding module 423 includes two front ends hinged to the first conveyor belt module 422. The guide plates 4231 are provided with a limit plate 4232 under each guide plate 4231. The extension direction of the rotation axis of the guide plate 4231 is perpendicular to the conveying direction of the first conveyor belt module 422. The limit plate 4232 can abut the bottom of the guide plate 4231 to prevent the guide plate 4231 from rotating downward. A plurality of first stop blocks 424 can pass between the two guide plates 4231 in sequence, and a second gap 4233 is formed between the two guide plates 4231. The first lifting rack 411 can be raised and lowered to pass through the second gap 4233. The length of the rotating workpiece 100 is greater than the second gap 4233.

[0052] After the defective products are measured at the re-measurement station, the first material lifting rack 411 lifts the defective products upward, and the defective products push the two guide plates 4231 to rotate upward during the rising process. When the defective products rise to the position where they are separated from the guide plates 4231, the two guide plates 4231 rotate downward under the action of gravity and conflict with the limit plates 4232. At this time, the guide plates 4231 tilt downward in the direction close to the first conveyor belt module 422, and then the first material lifting rack 411 drives the defective products to descend. The defective products are supported on the two guide plates 4231 when descending, and the first material lifting rack 411 continues to descend and pass through the second gap 4233. The defective products roll along the length direction of the guide plates 4231 to the first stopper 424, and then the first stopper 424 conveys the defective products forward, thereby completing the collection of defective products without the need for manual rejection of defective products, effectively improving the collection efficiency of defective products.

[0053] A second conveyor module 425 is also provided to the side of the first conveyor module 422. The second conveyor module 425 is also a belt conveyor and moves parallel to and synchronously with the first conveyor module 422. When defective products are conveyed on the first conveyor module 422, their ends can be supported on the second conveyor module 425 to prevent the defective products from deflecting and falling during the conveyance process.

[0054] The implementation principle of the dynamic balancing test deweighting device in the embodiment of the present application is: The conveying mechanism 4 continuously conveys the rotating workpiece 100 forward, and the transporting mechanism 2 transports the rotating workpiece 100 to the initial measurement station, the first deweighting station, the second deweighting station and the re-measurement station in sequence. The rotating workpiece 100 completes two tests and two deweightings respectively with the cooperation of the two testing mechanisms 5 and the two deweighting mechanisms 6. Then the transporting mechanism 2 sends the rotating workpiece 100 back to the conveying mechanism 4. If the rotating workpiece 100 is measured to be a defective product, the first lifting component 41 will lift the defective product onto the collection component 42.

[0055] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
