Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a deburring tooling for a plastic-sealed stator. Background Art

[0002] As Figure 7 For the plastic-sealed stator shown, removing the burrs on the edge of the stator after the plastic-sealing process is a crucial step. The existence of burrs will not only affect the assembly quality of the motor, but may also have an adverse impact on the running performance and service life of the motor. Therefore, developing an efficient and reliable deburring device is of great significance for improving the production efficiency and product quality of the motor stator.

[0003] The existing deburring devices for motor stators, as described in the published patent No. CN210125957U, have achieved the function of grinding and removing burrs from a single stator. The device includes components such as a workbench, a support frame for the motor stator, a driving motor, a driving wheel, a driven wheel, and a sand belt connecting the two. By the rotation of the driving motor, the friction force of the sand belt is used to remove the burrs on the edge of the stator. However, the existing technology also has some limitations. First, the device is only suitable for single-piece processing and cannot meet the requirements of large-scale production, which limits the production efficiency to a certain extent. Second, the single-piece processing method may lead to an increase in production costs because separate settings and adjustments of the equipment are required for each processing. In addition, single-piece processing may also increase the labor intensity of the operators and affect the production efficiency. Summary of the Utility Model

[0035] Stator positioning: Run the material channel cylinder, and its piston end drives the stator carrier plate to move along the slide rail on the bottom plate, accurately moving the stator tooling directly below the burr pressing block.

[0036] Deburring operation: Next, operate the deburring cylinder. Its piston end drives the tooling plate to move downward, causing the burr pressing block to contact the stator and start the deburring process.

[0037] Deburring completed: After the burr pressing block descends to the in-place position, the deburring operation is completed. Subsequently, the piston end drives the tooling plate to rise and return to the original position.

[0038] Stator carrier plate returns to position: After deburring is completed, the material channel cylinder returns to position, moving the stator carrier plate back to its original position along the slide rail, preparing for deburring the next stator or unloading the processed stator.

[0039] Unloading and cleaning: The operator unloads the stator that has completed deburring and cleans the burrs collected in the receiving hopper to keep the tooling clean and ensure the smooth progress of the next processing operation.
