Problems solved by technology

[0003] The connection structure between the spindle and the cutter body of the original CNC vertical drilling machine is usually a Morse taper hole matching connection. The first form has high requirements for the operator, and often the cutter body will appear during use because the operator does not meet the requirements when manually installing the tool. The phenomenon of falling off causes damage to the machine tool, thereby reducing the service life of the machine tool; second, the tool change time is long, which affects work efficiency

Abstract

The invention relates to a broach spindle for a numerical control vertical drill. The broach spindle is arranged in a spindle head body in a penetrating way and can move up and down relative to the spindle head body along the axial direction of the broach spindle, and a pneumatic tool changer is arranged in the broach spindle and comprises a booster cylinder, a push rod, a pull rod and a tool changing mechanism. In the machining process, the pneumatic tool changer is arranged in the broach spindle to carry out pneumatic tool changing by utilizing the booster cylinder, and a tool body is clamped by clamping jaws, so that the tool body is firmer when in use and not easily fall off; the booster cylinder controls the pull rod to move up and down, and the clamping jaws are clamped or loosened by a tension spring, so that the tool clamping and loosening effects are achieved, the tool changing time of the numerical control vertical drill is shortened, and the machining efficiency of the numerical control vertical drill is improved.

Description

technical field [0001] The invention relates to the technical field of a numerically controlled vertical drilling machine, in particular to a broaching spindle of a numerically controlled vertical drilling machine. Background technique [0002] As we all know, the high-speed spindle system has always been one of the three high-tech CNC machine tools. With the rapid development of numerical control technology and cutting tools, more and more mechanical manufacturing equipment is constantly developing towards high speed, high precision, high efficiency, and high intelligence. The built-in spindle unit has become the most suitable for the above high-performance working conditions. One of the core functional components of CNC machine tools. [0003] The connection structure between the spindle and the cutter body of the original CNC vertical drilling machine is usually a Morse taper hole matching connection. The first form has high requirements for the operator, and often the c...
