Description

Technical Field

[0001] The utility model belongs to the technical field of boring mechanisms, and relates to an automatic boring mechanism for sewing machine components. Background Art

[0002] Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the hole diameter, improve accuracy, reduce surface roughness, and can also better correct the deviation of the original hole axis. For some small structural parts, using a honing machine to finish boring them is a good way. When the small structural parts in the existing sewing machines, especially the internal rocker-shaped parts, are mass-produced, they are processed by honing machines quickly and conveniently, and the internal holes are smooth. However, when the honing machine is currently processing, it is necessary to install tooling on the main clamping plate to support the workpiece. Usually, a plate with screws is screwed on the main clamping plate for support. This will cause multiple adjustments and alignments during the processing process, which is troublesome to operate. When the workpieces are of different sizes, the support plate must be disassembled and re-selected, and then installed. The procedure is cumbersome and the work efficiency is low.
