The invention relates to an electric cabinet
metal plate milling device which comprises a
machine tool and a vacuum adsorption carrying table
assembly of the
machine tool. The
assembly comprises an adsorption platform
deck, a base and an integrated valve terminal, a negative pressure through hole in the adsorption platform
deck is divided into a negative pressure concentration area and a central adsorption area, the bottom is connected with the integrated valve terminal through a
pipe joint, and a
proximity sensor is arranged on the outer side.
Suction force of different areas is subjected to partition management through the integrated valve terminal, and the adsorption force can be dynamically adjusted according to the position of the
milling cutter. When the
milling cutter approaches, the
valve opening degree of the corresponding area is adjusted through the integrated valve terminal, reasonable distribution of
suction force is achieved, and the suction requirement of the
milling cutter during
machining at different positions of a thin plate can be met even if the total
suction force is constant. In addition, a
chip blowing mechanism is further arranged, chips can be blown away,
false alarm of the sensor is prevented,
machining reliability and efficiency are ensured, and the milling quality of the electric cabinet thin plate with the thickness being 1 mm is improved.
