During the processing and use of the circuit breaker, burrs on the circuit breaker need to be cleaned, and therefore a deburring device needs to be used.

[0003] However, the common deburring device is usually driven by a pneumatic cylinder to cut the burrs. Due to the existence of tolerances, it is difficult to make the edges of the opening neat and smooth by cutting only once, and the cut opening needs to be processed repeatedly. The traditional deburring device is cumbersome and difficult to process efficiently. In view of the above-mentioned related technologies, the applicant proposes a deburring device capable of efficiently processing the burrs repeatedly. CONTENT OF THE INVENTION

[0007] By adopting the above technical scheme, the driving structure with the movable end is arranged on the rack, the deburring structure is slidably connected to the movable end of the driving structure, and the high-frequency vibration is realized through the elastically connected vibration structure. The high-frequency vibration generated by the vibration structure enables the deburring tool to contact the surface of the circuit breaker base more uniformly, so that a smoother and flatter surface quality is obtained, and the overall quality of the product is improved. This design makes the deburring process more stable and efficient, reduces manual intervention, and improves the automation level.

[0017] The rack is provided with a driving structure having a movable end, the deburring structure is slidingly connected to the movable end of the driving structure, and high-frequency vibration is realized through the elastically connected oscillation structure. The high-frequency vibration generated by the oscillation structure enables the deburring tool to more uniformly contact the surface of the circuit breaker base, thereby obtaining a smoother and more even surface quality and improving the overall quality of the product.

This design ensures that the cutting knife can accurately fit the profile of the circuit breaker base, effectively removing small and hard-to-reach burrs, improving the deburring effect and precision. The deburring structure not only includes a cutting knife but also is equipped with a cleaning brush. The cutting knife is used to preliminarily remove larger burrs, while the cleaning brush is used to further clean small burrs and debris. This dual processing mechanism ensures a smoother and more even surface, improving the overall quality of the product.

[0019] The inclined arrangement enables the cleaning brush to clean the workpiece from multiple directions through up-and-down reciprocating action during work, not only removing surface burrs but also cleaning fine gaps and grooves. This all-around cleaning method significantly improves the cleaning effect, ensuring a smoother and more even surface of the workpiece. BRIEF DESCRIPTION OF DRAWINGS
