Abstract

The invention discloses a vertical gear hobbing machine which comprises a rack, as well as a bracket and a stand column arranged on the rack, wherein a working table is arranged on the bracket; a hobbing power head assembly is arranged on the stand column and is characterized by comprising a hobbing cutter installing device, a hobbing slewer and a cutter channeling device; the hobbing cutter installing device comprises a relay shaft assembly and a cutter channeling spline shaft; the relay shaft assembly comprises a spline housing fixedly arranged on a hobbing rotary table; the spline housing is matched with the upper section of the cutter channeling spline shaft; the lower section of the cutter channeling spline shaft is connected and fixed with a flat key groove, and the flat key groove is formed in the central hole of a hobbing cutter; the cutter channeling spline shaft is provided with a central hole; a T-shaped pull rod is inserted in the central hole; a plurality of disc springs are arranged on the pull rod in a sleeving manner, and the pull rod is arranged between the pull rod head and the upper end part of the cutter channeling spline shaft; the upper end face of the pull rod is propped against the lower end face of a disc spring ejector rod; the disc spring ejector rod is connected with the piston rod of a hobbing cutter tensioning oil cylinder; and the upper end face of the pull rod is matched with a cutter buckle assembly. Compared with the prior art, the vertical gear hobbing machine has higher machining precision.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a vertical gear hobbing machine. Background technique [0002] Gear hobbing machine tools can be divided into two categories: horizontal and vertical according to their structural layout. Generally speaking, because the direction of gravity of the workpiece is the supporting frame of the vertical gear hobbing machine, its force is good and it is suitable for processing large and heavy gears. Gear machining and hobbing of gears with high precision requirements. [0003] The vertical hobbing machine is indispensable for the rotary table. The rotary table is one of the important guarantees for the tooth profile development movement during the gear hobbing operation. Its structure and motion accuracy directly determine the quality of the tooth profile processing. The current rotary table is manually adjusted. The adjustment of the swinging head angle is labor-intensive ...
