Description

Technical Field

[0001] The utility model relates to equipment for processing stator cores, belonging to the technical field of motor production equipment. Background Art

[0002] The stator core is an important component that constitutes the motor magnetic flux circuit and fixes the stator coil. It is formed by pressing a number of stator laminations through a stator automatic riveting and pressing device. In order to improve the tightness between the stator laminations, a stator clamping device is required to further press the stator core. This is disclosed in the announcement numbers CN209329916U, CN215943959U and other applications. However, the pressing process may result in uneven force and fail to achieve the expected pressing effect. Currently, screening is usually not performed after pressing.

The measured stator core is pushed to the rejection device through the telescopic cylinder three 23. The rejection device includes a rejection component and a rejection guide rail 5 arranged on both sides of the conveying guide rail, wherein the rejection component includes a telescopic cylinder four 4. The telescopic cylinder four 4 is controlled by the control device to push the stator core that does not meet the height requirement from the conveying guide rail 3 to the rejection guide rail 5, and the stator core that meets the height requirement continues to be transported along the conveying guide rail 3. The control device is connected with the pushing component, the sensor 15, the stator clamping device 2, the measuring device 6 and the rejection device to realize automatic clamping and screening separation of the stator core.

[0014] As a preferred embodiment, it includes a stator conveying device, which includes an inclined guide rail 7. The stator cores are arranged on the guide rail 7 and slide down into the conveying guide rail 3 under the action of gravity. The stator cores can slide down from the guide rail 7 into the conveying guide rail 3 one at a time. A telescopic cylinder 5 8 and a telescopic cylinder 6 9 are provided on the guide rail 7. When the telescopic cylinder 5 8 is extended, it blocks the last stator core on the guide rail. The telescopic cylinder 6 9 is extended to press the second-to-last stator core on the guide rail 7 against the guide rail 3. The telescopic cylinder 5 8 contracts to release the blockage. The last stator core is slid into the conveying guide rail 3. Since the telescopic cylinder 6 9 presses the second-to-last stator core against the front stator core, it is also blocked and cannot slide down. Then the telescopic cylinder 5 8 is extended. Cylinder six 9 contracts, and the original second-to-last stator core slides to the position of the last stator core, and the above action is repeated to realize the delivery of the stator cores one at a time to the delivery guide rail 3.

A row of support rollers 11 are distributed along the length of the guide rail 7 between the two baffles 10 and 10A. The two baffles 10 and 10A limit the two sides of the stator core. The stator core is rolled on the support rollers 11 to reduce friction and facilitate the sliding of the stator core. The telescopic cylinder five of the present application is arranged at the bottom of the guide rail 7. When extended, it extends from between two adjacent support rollers 11 to block the stator core. The telescopic cylinder six 9 is installed on the outside of the baffle 10. When extended, it passes through the baffle 10 to tighten and fix the stator core and the baffle 10A.
