Collapsible honing head

Abstract

The invention discloses a collapsible honing head, relates to the technical field of honing and aims at solving the technical problem that the prior collapsible honing head is incapable of directly honing a workpiece with a groove or gap wider than a single oilstone. The honing head comprises a shell, a collapsible element which is arranged on the shell and is collapsible in the radial direction, an oilstone seat arranged on the collapsible element and an oilstone arranged on the oilstone seat. The honing head is characterized in that the oilstone seat is an open lantern ring sleeved and fixed on the collapsible element; the peripheral surface of the open lantern ring is provided with at least one oilstone in parallel along the axial direction; and the open lantern ring and the oilstone can swell and shrink along with the collapsible element. Due to the utilization of the collapsible honing head, the labor productivity and the product quality can be improved.

Description

technical field [0001] The invention relates to the technology of the honing head, in particular to the technology of an expanding-shrinking honing head capable of directly processing workpieces with grooves or notches wider than a single whetstone. Background technique [0002] The current expansion-contraction honing head is equipped with multiple oilstone seats, and a strip-shaped oilstone is arranged on the oilstone seat. The honing rod drives the oilstone on the honing head to rotate and move axially to honing the inner hole of the workpiece. Equipped with an expansion and contraction mechanism to make the oil stone base radially expand, and contact with the inner hole of the workpiece and expand tightly, so that many products with a hole diameter larger than the honing head can be honed, and the honing efficiency and quality can be improved. However, each oilstone seat of this expansion-contraction honing head is independently stressed, and the shape of the oilstone is...

AI Technical Summary

Problems solved by technology

However, each oilstone seat of this expansion-contraction honing head is independently stressed, and the shape of the oilstone is elongated, so when processing an inner hole with a groove or a gap wider than a single oilstone, the oilstone When passing through the groove or gap, the radial resistance will be lost, and the oil stone will sink into the groove or gap under the action of radial tension, thus damaging the edges and corners of the groove or gap

For this kind of workpiece with grooves or gaps, it can only be processed by ordinary honing tools after filling the gap. This method is difficult to operate in actual production, and the labor productivity is very low, and the quality cannot be guaranteed.
