AI Technical Summary

Technical Problem

During the drilling process of bevel gears, there are problems such as inaccurate positioning, drilling position deviation, and residual debris affecting assembly accuracy. In addition, the drill bit is prone to jamming, which affects the processing progress.

Method used

By employing a combination of a rotary drive mechanism, a clamping mechanism, and a drilling mechanism, and through a dual fixing structure of radial rack clamping and elastic contact with the deflection rod, coupled with a servo motor drive and a negative pressure system, the bevel gear achieves stable limiting, precise positioning, and synchronous debris removal.

Benefits of technology

Ensure the stable fixation and precise positioning of the bevel gear during drilling to avoid chip accumulation, improve machining accuracy and equipment life, and reduce subsequent cleaning processes.

Abstract

The invention relates to the field of bevel gear drilling, in particular to a bevel gear pre-heating rough machining process which comprises a rotary driving mechanism, and a machining table is arranged on the rotary driving mechanism and used for driving the machining table to rotate and removing chippings on the top of the machining table; the drilling mechanism is arranged on the outer side of the machining table and used for drilling the center of the bevel gear; the clamping mechanism is arranged on the machining table and is used for carrying out all-directional clamping treatment on the bevel gear; the drilling mechanism comprises a bottom plate, the bottom plate is arranged on the outer side of the rotary driving mechanism, a supporting rod is fixedly installed at the top of the bottom plate, a transverse rail is fixedly installed at the top end of the supporting rod, and a sliding block is slidably matched with the interior of the transverse rail. The rubber groove is matched with the curved surface of the bevel gear, so that the temporary limiting and displacement preventing effects are achieved, and drilling impact can be buffered.
