Heavy gear transmission vertical broaching machine tool

Abstract

The invention discloses a heavy gear transmission vertical broaching machine tool. The heavy gear transmission vertical broaching machine tool comprises a base and a machine tool body, wherein the machine tool body is fixed on the base; a guide rail extending in the vertical direction is arranged on the machine tool body; a main slide carriage driven by a power device and linearly moving in a reciprocating way is arranged within the guide rail; the power device comprises an electric motor and a driving shaft; the driving shaft is connected to an output end of the electric motor; a driving gear is arranged on the driving shaft; a driving rack adaptive to the driving gear is fixed on the main slide carriage; a clamping device for fixing a broaching tool is arranged on the main slide carriage; the heavy gear transmission vertical broaching machine tool also comprises a workbench arranged on the base; and a fixing device for fixing a workpiece is arranged on the workbench. The heavy gear transmission vertical broaching machine tool disclosed by the invention has the advantages of simple transmission mode and convenience for mounting and is very suitable for broaching heavy and large-sized workpieces; the bearing capacity of the broaching machine tool can be effectively enhanced so that the transmission is stable and the error generated in the machining process is largely reduced; and the fault source can be accurately figured out in time after the fault occurs so that the maintenance time is reduced.

Description

technical field [0001] The invention relates to the technical field of vertical broaching machines, in particular to a heavy-duty gear-driven vertical broaching machine tool. Background technique [0002] The vertical broaching machine in the prior art usually includes a base, on which a bed is arranged, and a main slide that can move up and down is arranged on the bed, and also includes a hydraulic drive device for driving the main slide. The broach on the main slide completes the processing of the workpiece. Since the hydraulic drive device is a complex electromechanical-hydraulic integrated system, once the system fails, it is often difficult to accurately determine the source of the system failure in a short period of time. Can rely on experience for analysis, resulting in slow maintenance and low work efficiency; and the vertical broaching machine with this structure is only suitable for processing light and small workpieces, not suitable for heavy and large workpieces,...
