Automatic processing machine for bearing inner ring screw hole

Abstract

The invention provides an automatic processing machine for a bearing inner ring screw hole. The automatic processing machine comprises an engine base and a turntable, wherein the turntable can rotate in an indexing intermittent mode under the action of a power transmission device; the periphery of the turntable is uniformly provided with clamps for clamping workpieces; drilling devices, tapping devices, hole detection devices, burr filing devices and feeding and discharging mechanical arms are arranged around the turntable; all the devices are corresponding to positions where the clamps on the turntable stay; the hole detection devices are arranged on the downstream sides of the drilling devices and tapping devices; the burr filing devices operate after the completion of screw hole detection; the feeding and discharging mechanical arms are respectively linked with a feeding device and a discharging device. By adopting the automatic processing machine, feeding, drilling, tapping, burr removing, and discharging can be automatically realized, and only one operator is needed for carrying out management and monitoring; the labor intensity is greatly reduced, the production efficiency is high, the processing cost is low, and the product quality is stable.

Description

technical field [0001] The invention relates to the technical field of bearing production, in particular to an automatic processing machine for screw holes in inner rings of bearings. 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. like figure 1 As shown, this kind of bearing is processed with two screw holes, namely screw holes, on the inner ring of the bearing. The angle between the screw holes is 120°. to the fixed effect. 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...

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. Finally, the tapping process is carried out, and another one or two devices are needed. The workpiece must be clamped once for each threaded bottom hole or screw hole, and the workpiece must be transferred between the devices. Finally, it is necessary to manually file and remove the burr at the end of the screw hole. The labor intensity of the workers is high, the processing efficiency is low, and a large number of personnel and labor hours are required, and the processing cost is high.
