Abstract

The invention discloses a broaching machine for machining an arc groove, especially an arc tenon tooth groove. The broaching machine comprises a broaching tool, a broaching tool driving mechanism for driving the broaching tool to move and a workpiece positioning mechanism for positioning a workpiece. The broaching tool comprises a rotary disc and a tool tooth portion connected with the rotary disc. The tool tooth portion is provided with a first tool tooth portion end and a second tool tooth portion end. The tool tooth portion comprises multiple tool teeth distributed between the first tool tooth portion end and the second tool tooth portion end. The tool teeth are arranged in an arc shape concentric with the rotary disc. At least one of the heights and the widths of the tool teeth are gradually increased from the first tool tooth portion end to the second tool tooth portion end. The broaching tool driving mechanism is used for driving the broaching tool to rotate around the first axis to machine the arc groove in the workpiece.

Description

technical field [0001] The invention relates to a broaching tool, in particular to a broaching machine and a broach capable of processing arc-shaped grooves, such as a broaching machine and a broach for processing turbine arc-shaped mortise and tooth grooves. Background technique [0002] A broach is a cutting tool consisting of many teeth of increasing size. When it moves linearly along its axis under the action of pulling or pushing, its teeth cut off a thin layer of metal on the workpiece one by one, so that the workpiece can obtain a certain shape, size, precision and smoothness. inner or outer surface. The continuous progress of the cutting process is realized by using the rear tooth of the broach to increase a certain tooth width or tooth height (that is, the amount of tooth lift) compared with the previous tooth. But the current broaches can only process straight grooves or holes, and can't do anything for arc grooves. For example, a gas turbine includes a disk and...
