Description

Planet carrier processing device and planet carrier processing method

Technical Field

The present invention relates to the technical field of machining, and in particular to a planet carrier machining device and a planet carrier machining method.

Background Art

As one of the most important components of the planetary gear transmission mechanism, the planet carrier is used to install the planetary gear shaft or bearings.

Since the quality of the planetary carrier will directly affect the running stability and reliability of the planetary gear transmission mechanism, in order to ensure the correct engagement of the sun gear, planetary gear and ring gear in the planetary gear transmission mechanism, the processing position accuracy of the planetary gear shaft holes of the planetary carrier is generally required to be relatively strict.

At present, the processing of planetary shaft holes is mainly completed on vertical machining centers, and its processing technology specifically includes the following steps: rough machining of planetary shaft holes, semi-finishing boring, scraping of inner surface, fine boring and chamfering of hole mouths; the existing processing methods, from rough boring, semi-finishing boring, scraping of inner surface to fine boring and chamfering, require at least five tools, plus the investment of the vertical machining center itself, the total investment is large, and the comprehensive cost of processing and manufacturing is high; at the same time, due to the need to equip and install corresponding positioning fixtures for different processes, production is intermittent and discontinuous, and production efficiency is low.

In response to the above problems, a Chinese invention patent with patent number CN109693129B discloses a planetary carrier processing device and a planetary carrier processing method; the workpiece and the second positioning plate are fixed by an installation structure, so that the clamping and positioning of the workpiece are realized, and the accuracy of the planetary shaft hole processing is guaranteed: the first tool mechanism is penetrated into the planetary shaft hole of the workpiece, so that the processing of the planetary shaft hole is realized; by setting the second positioning plate to be detachably connected to the first positioning plate, the second positioning plate can rotate relative to the first positioning plate, and after the two are separated and rotate relative to each other, it is convenient for each planetary shaft hole to be processed in sequence. Through this setting, the planetary shaft hole processing can be realized without the need for additional multiple positioning fixtures, the structure is simple, the operation is convenient, the production cost is saved, and the time for replacing the positioning fixture is reduced, thereby improving the production efficiency.

Although the above scheme is relatively convenient to operate and can fix the planetary carrier without multiple positioning fixtures, it saves production costs and improves production efficiency to a certain extent; but its applicability is relatively poor, and the disassembly and assembly process requires full manual participation, which is labor-intensive and not conducive to mechanical automation production. After use, it is difficult and time-consuming to clean residual iron filings and other debris; and it is easy to cause damage to the processed planetary carrier during use.
