Broaching machine used for machining key grooves

Abstract

The invention relates to a broaching machine used for machining key grooves. The broaching machine comprises a machine body (1), a working table (5) and a clamp (4). The machine body (1) is provided with a broach (3). The working table (5) is connected with the machine body (1) and located below the broach (3). The upper end face of a side plate (502) of the working table (5) comprises an inclination section and a horizontal section. The clamp (4) is arranged on the working table (5) in a sliding manner. A middle plate and a bottom plate of the clamp (4) are connected in a sliding manner. Thebottom plate is provided with at least one first guide rod (410). First guide holes are formed in the corresponding positions of the middle plate. The first guide rods (410) penetrate through the first guide holes. Each first guide rod (410) is provided with a spring (413). The springs (413) abut against the upper surface of the middle plate. According to the broaching machine, when the clamp (4)moves on the working table (5), the height can be adjusted automatically, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of broaching machines, in particular to a broaching machine for processing key grooves. Background technique [0002] Broaching machine is a widely used processing machine tool. However, the broach works in a straight line, and the broaching teeth of the broach are in contact with the surface of the workpiece during operation, thereby machining grooves on the workpiece. Therefore, in order to avoid contact between the broach and the workpiece during the reset process, the position of the workpiece will be shifted, which will affect the machining accuracy; or cause damage to the broach and the workpiece, resulting in production loss. Therefore, it is often necessary to reset the broach before fixing the workpiece on the tooling, especially when processing the inner ring of the ring-shaped workpiece, it is necessary to put the ring-shaped workpiece on the broach, and then fix the workpiece on the fixed toolin...
