Abstract

The invention relates to a small-hole grinding tool of a drilling machine for correcting hole diameter. The small-hole grinding tool comprises a grinding mandrel; the grinding mandrel is a conical shaft, and the large-diameter end thereof is a clamping part; the clamping part is provided with a circular slot in the radial direction, and an open-ended steel wire ring is arranged in the circular slot; and the other side is a working part, and the working part is sleeved with an open-ended grinding sleeve in a matching way. When in use, the small-hole grinding tool is directly arranged on a chuck of the drilling machine; and the diameter of a small hole on the drilling machine which deforms and is out of round after thermal treatment and hardening is corrected under the premise of keeping the position of a traditional work piece hole, and the self-centering and automatic abrasive supply functions can be realized.

Description

technical field

[0001] The invention relates to a small hole grinding tool for correcting the hole diameter of a drilling machine. Background technique

[0002] At present, diamond reamers are mostly used for trimming small holes that are deformed and out of round due to heat treatment and hardening on parts. However, due to the difference in aperture diameters, diamond reamers need to be customized and multiples must be customized according to the amount of trimming, which is not only a waste of money. , and the operation is very inconvenient. Contents of the invention

[0003] In order to solve the problem that many tools need to be customized for the small hole diameter modification due to deformation and out-of-roundness after heat treatment and hardening, the invention provides a small hole grinding tool for correcting the hole diameter.

[0004] The specific structural design scheme is as follows:
