Rotary type processing equipment for threaded holes of bearing inner ring

Abstract

The invention discloses rotary type processing equipment for threaded holes of a bearing inner ring. The rotary type processing equipment comprises a fixed plate, a rotary plate, a first stop device, a second stop device, a drilling device, a tapping device and a drive device, wherein the outer side edge of the fixed plate is provided with an engagement part; the engagement part consists of a plurality of first teeth; the part, positioned at the periphery of the fixed plate, of the upper end surface of the rotary plate is provided with a rotatable workpiece mounting plate; the outer side edge of the workpiece mounting plate is uniformly distributed with a plurality of second teeth adaptive to the first teeth; the first stop device is used for stopping the workpiece mounting plate; the drilling device is used for drilling the inner ring of the workpiece mounting plate; the second stop device is used for stopping the workpiece mounting plate; the tapping device is used for tapping the drilled inner ring; and the drive device is in transmission connection to the rotary plate for riving the rotary plate to rotate around the fixed plate and to rotate towards the tapping device from the drilling device. The rotary type processing equipment can complete twice drilling and twice drilling by once clamping, so that the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a rapid processing device for threaded holes in the inner ring of a rotary bearing. Background technique [0002] The outer spherical ball bearing is a kind of deep groove ball bearing. It has the inner ring of the bearing, the outer ring of the bearing, and the rolling element between the inner ring of the bearing and the outer ring of the bearing. Advantages, the use environment of the outer spherical ball bearing is generally relatively harsh, the vibration of the shaft is large, and the concentricity of the bearing seat is not high. This kind of bearing is processed with two top screw holes, namely screw holes, on the inner ring of the bearing, and a certain angle is formed between the two screw holes. Thereby play a fixed role. The machining of the two screw holes in the inner ring of the bearing currently uses two drilling machines to process the bottom holes o...

AI Technical Summary

Problems solved by technology

The machining of the two screw holes in the inner ring of the bearing currently uses two drilling machines to process the bottom holes of the two screw holes separately. Because the positions of the drilling holes are different, different workpiece positioning fixtures are used to process the two screw holes. After that, the tapping process needs another one or two equipments. Every time a threaded bottom hole or screw hole is processed, the workpiece must be clamped once, and the workpiece must be transferred between the equipments, resulting in high production efficiency. Poor and in need of improvement
