Upward-pulling type broaching machine toolchanger

Abstract

The invention belongs to the technical field of broaching machines and provides an upward-pulling type broaching machine toolchanger. The toolchanger comprises a base, a broaching machine body, a tool lifting and sending assembly, a tool changing assembly and a tool library assembly arranged beside the base, wherein the broaching machine body, the tool lifting and sending assembly and the tool changing assembly are vertically fixed to the base; the tool changing assembly is arranged on the broaching machine body, and the tool lifting and sending assembly and the tool changing assembly are in hung connection. The upward-pulling type broaching machine toolchanger has the advantages that in the upward-pulling type broaching machine toolchanger, the tool lifting and sending assembly is matched with the tool changing assembly and the tool library assembly to move in the X direction, the Y direction and the Z direction, under the control of a numerical control system, automatic broach changing of a broaching machine is achieved, labor intensity of operation staff is lowered, production efficiency is improved, and safety risks existing in the tool changing process is further lowered; automatic tool changing of the broaching machine is achieved, the tool changing speed is high, and accuracy is high; and in an automated production line, a broaching machine process can be embedded into the automated production line, manufacturing automation and intelligence are achieved, and the upward-pulling type broaching machine toolchanger has wide development prospect.

Description

technical field [0001] The invention belongs to the technical field of broaching machines, and in particular relates to a tool changing device for a pull-up type broaching machine. Background technique [0002] In mechanical processing, for example, gears are one of the most common power transmission elements, and torque is transmitted through a gear pair formed by two matched gears, which is widely used in power transmission of automobiles or motorcycles. And gear owing to need cooperate with gear shaft, on the internal circle of gear, all need be provided with the keyway, tooth groove etc. that cooperate with the outer circle surface of shaft, could drive mutually between gear and gear shaft, rotate together. At present, the keyway, tooth groove, etc. are processed on the inner circle of the gear. The gear blank is fixed on the tooling of the broaching machine on the broaching machine, and then the broach is passed through the inner hole of the gear, and the broach is driv...
