Novel grinding tool for inner bore

Abstract

The invention discloses a novel grinding tool for an inner bore. The tool comprises a fixed handle and a grinding rod, wherein the fixed handle is provided with a cavity, an outer cover is arranged outside the cavity, and the cavity is provided with an air inlet pipe; the grinding rod is hollow, the radial surface of the grinding rod is uniformly provided with three or more expandable grinding rod capsules. The novel grinding tool for the inner bore provided by the invention has the advantages that the inner core can be enlarged to one thousandth of a millimeter by a grinding way; furthermore, multiple times of grinding can be performed by adopting a grinding piece of same roughness to find out a rule of grinding time in such ways of presetting grinding pressure, adjusting force applied to the inner wall of the bore and performing grinding measurement once according to given revolving speed during grinding, expanding frequencies and grinding time; in addition, by adopting grinding pieces of different roughness to perform process arrangement grinding, the degree of finish of an inner bore surface is higher, and the operating time is shorter.

Description

technical field [0001] The invention relates to a grinding tool, in particular to a novel inner hole grinding tool. Background technique [0002] There are quite a lot of hole fits in mechanical production and assembly. Each hole is processed according to the required precision. The processing procedure of high-precision holes plays an important role in the quality and assembly of products. The reliability of hole accuracy has a great impact on the production cost of enterprises. and production time have a greater impact. [0003] In the method of general parts processing, different machine tools are selected according to the requirements and completed according to different processes. The actual shape and position tolerances after processing are also different. For the straight holes assembled, the follow-up processing is completed by grinding. The current existing grinding method is to use The grinding rod is clamped on the main shaft of the rotatable telescopic machine t...

[0003] In the general part processing method, different machine tools are selected according to the requirements and completed according to different processes. The actual shape and position tolerances after processing are also different. For the straight holes assembled, the subsequent processing is completed by grinding. The current existing grinding method is to use Grinding rods are clamped on the main shaft of the rotatable telescopic machine tool and coated with grinding paste for grinding. When producing holes of various sizes, it is necessary to prepare grinding rods of various sizes, which will increase production costs and reduce production efficiency.
