Novel main shaft broach mechanism with integrated pull claw

Abstract

The invention discloses a novel high-speed spindle broach mechanism with an integrated pull claw. The device structurally comprises a main shaft core, a BT cutter handle, a blind rivet, an integrated pull claw, a water spraying ejector rod, a trapezoidal groove pull head, a broach rod, a water spraying ejector rod threaded connection sleeve, a pushing spring, a disc spring front pad, a disc spring set, a disc spring middle gasket, a middle water guide rod, a shaft core rear cover, a middle connection ring, a rear connection pressing ring, a rotary connector installation rod, a bearing supporting ring, a distance ring and a rear water guide rod. The novel main shaft broach mechanism is designed for a horizontal machining center main shaft of a high-end numerical control machine tool, and the integrated pull claw is adopted, so that the rotating speed of the main shaft can be effectively increased due to good rotating dynamic balance; the stability of tool loosening and pulling actions can effectively assist in improving the stability of automatic tool changing of the horizontal machining center, and by combining a new machining technology of high-pressure cutting water spraying, the machining efficiency can be effectively improved, the cutting performance can be improved, the service life of a tool can be prolonged, tool loss can be reduced, and the machining cost can be saved.

Description

Technical field [0001] The present invention relates to the field of machine tool components, and specifically, an new high-speed spindle mechanism applied to a horizontal machined heart shaft, a claw is an integrated, and a spindle center can spray water, the front end of the spindle. Background technique [0002] Horizontal machining center, CNC boring machine, opposite machining center, no matter how much technical barriers are highly difficult, complexity, most of the domestic CNC machine tool manufacturers are concentrated in the production of medium and low-end machining centers, while production horizontal processing The center manufacturer is not numbered, and the high-precision horizontal machining center can be less, but there are many superiority of the vertical machining center of the horizontal machining center, first of all the workbench is open, facilitating the installation of the workpiece, can be installed Large-scale rotating workbench can be installed to impro...

AI Technical Summary

Problems solved by technology

The main shaft of the horizontal machining center is set horizontally. When the broaching mechanism is in the same horizontal state, water is easy to accumulate in the taper hole of the main shaft, and the ring spring is easy to rust when the ring spring is slightly longer. (The fatigue life of the stainless steel spring is not as good as that of the spring steel). The spring elastic tie makes the front end of the claw claws open. When the ring spring fails or the elastic force is small, the two upper pieces of the claw claws that are opened will sag under the action of their own weight, and the handle will be stuck. Pulling the nail, when the automatic tool changer manipulator pulls out the knife, the knife may fall off, or the knife may be stuck and cannot be pulled out;

[0004] For the cutting process of horizontal machining centers, water spray pipes are generally installed on the front of the spindle to spray water for cooling, but it still cannot achieve a strong cooling effect and greatly improve the cutting efficiency;
