Abstract

The invention discloses a window processing method for a planetary part. The window processing method comprises the following steps of: step a. determining a processing area, and processing a window cutting line on the planetary part according to design requirements to form a window processing area; step b. performing drilling operation, to be specific, spraying cooling liquid, forming a through hole by vertically drilling the window processing area so as to remove part of machining allowance, and forming a space in to which a milling cutter stretches, a chip removal channel and a cooling liquid channel in the through hole; and step c. performing milling operation, causing the milling cutter to stretch into the through hole for milling operation, assisting in cooling by adopting the cooling liquid so as to remove the machining allowance, and then performing finish machining to obtain a window of the planetary part. According to the window processing method for the planetary part, firstly the through hole is processed by high-efficiency drilling so as to quickly remove part of the allowance, meanwhile the through hole provides the chip removal channel and the cooling liquid circulating channel for milling, and then the milling cutter stretches into the through hole for cutting so as to remove the machining allowance. The entire cutting edge for the milling is uniformly stressedto avoid the excessive loss of the cutting edge.

Description

Technical field [0001] The invention relates to the field of speed reducers, in particular, to a method for processing a window of a floating star part. Background technique [0002] The middle star structure part of the reducer is the main structure part of the reducer. The part contains multiple window structures. The windows are used to install the star gear parts to form a complete star structure part for deceleration. Such as figure 1 with figure 2 As shown, the window is regarded as a rectangular structure, and the machining allowance is relatively large. Before processing, the window is a solid structure, and the machining is usually performed by removing the allowance by layer-by-layer milling. The layer-by-layer milling method uses the milling cutter to mill from the outside of the window layer by layer to remove the margin. During the milling process, the front end of the milling cutter blade is mainly involved in cutting, which makes the use efficiency of the milling ...
