Abstract

The invention provides a cutter bar tailstock for clamping taper sleeves. The cutter bar tailstock is precisely clamped and assembled on a cutter bar to form a rotating body by adopting two oppositely-installed precise elastic taper sleeves and a pair of biserial cylindrical roller bearings with inner taper holes. After the tailstock with an integrated structure the cutter bar penetrates through is installed in place, the rigidity and precision of the cutter bar in work are ensured, the taper sleeves and the tailstock are quick and convenient to install and dismount, and the cutter bar tailstock is suitable for tail-end supporting of long rolling and milling rotary cutters.

Description

technical field [0001] The invention relates to a cutter bar tailstock clamped by a precision elastic cone sleeve, in particular to a cutter bar tailstock used for installing long hobbing and milling rotary cutting tools. Background technique [0002] In some cutting machine tools for hobbing and milling, hobs and milling cutters are installed on the cutter bar for rotary cutting. The front end of the tool bar is connected to the tool spindle of the machine tool to obtain the force required for cutting and the accuracy and stiffness. If the cutter is short, the motion accuracy and rigidity of the cantilever beam installation of the cutter rod can generally meet the processing requirements, but if the cutter is long, the motion accuracy and rigidity of the cutter rod tailstock are relatively low under the action of cutting resistance. The front end is descending geometrically, which obviously cannot meet the requirements of processing operations. At this time, it is necessa...
