[0040] The present invention discloses a high-precision automatic trimming device for hardware parts. By adopting a laser cutting head 270 as a trimming tool and cooperating with a fitting part 260 that fits tightly with the side wall of the hardware, an adjusting part 250 can lead the laser cutting head 270 to perform trimming operations along the contour of the hardware to be trimmed. The trimming operation does not require manual operation throughout the process, has a high degree of automation, can be applied to special-shaped hardware with complex shapes, and ensures the accuracy of trimming.

[0041] In this embodiment, a lifting assembly 110 is disposed between the operating table 100 and the bracket 120 . The lifting assembly 110 is used to drive the bracket 120 to move up and down, so as to adjust the height of the trimming mechanism 130 .

A pin 620 that is correspondingly plugged into the disassembly interface 420 is formed on the side wall of the locking piece 430.

[0065] Through the above structure, the adjusting member 250 can be limited in the axial direction to prevent the adjusting member 250 from rotating during edge cutting.

[0066] In this embodiment, a first magnetic block is disposed on the inner wall of the disassembly interface 420 ; and a second magnetic block adsorbed to the first magnetic block is disposed on the latch 620 .
