Abstract

The invention discloses an automatic tool changing spindle device of a PCB edge drilling and milling machine. The automatic tool changing spindle device comprises a spindle, a clamping block, air cylinder assemblies, guide rod assemblies, an induction assembly, a dust collection assembly and a press foot assembly; the spindle penetrates a central hole of the clamping block to be mounted, and the center line of the spindle coincides with the center line center hole of the clamping block; the two sides of the symmetric face of the clamping block are each provided with one guide rod assembly, and each guide rod assembly comprises a guide rod located in a clamping block guide rod hole and a linear bearing tightly attached to the guide rod; the air cylinder assemblies are arranged over the guide rods, and the press foot assembly is arranged under the guide rods; air cylinder flotation joints of the air cylinder assemblies can be inserted into round holes in the tops of the guide rods to be in interference fit with the guide rods, and the spindle is in interference fit with a press foot table of the press foot assembly; and accordingly, air cylinders can drive the guide rods, the press foot assembly and the spindle to vertically move in the clamping block to achieve automatic tool changing work.

Description

Technical field: [0001] The invention relates to the technical field of PCB board processing, in particular to an automatic tool changing spindle device of a PCB board edge machine. Background technique: [0002] In the production process of PCB circuit boards, the gong edge machine is mainly used to drill small round holes on the circuit board. The main shaft device of the gong edge machine is the main processing part of the drilling machine, which is composed of the main shaft and the main shaft fixture. The lower part of the spindle is the processing tool. The tool changing device in the prior art is a manual tool changing, which has low efficiency and needs to be improved. Invention content: [0003] The purpose of the present invention is to provide a new automatic tool change spindle device for PCB board edge machine, which has the characteristics of fast tool change speed and high production efficiency. [0004] To achieve the above object, the technical scheme ad...
