Embodiment Construction

[0039] Refer to the attached figure 1 The shown automatic expansion-contraction scraping-rolling combined boring head includes a rough boring head 1 with a rough boring head body 3 and a connection part for connecting to a boring bar, and is characterized in that it also includes a scraping part and a rolling part, And a mandrel 9 with a center hole that coaxially assembles the rough boring head, the scraping part and the rolling part sequentially from front to back; wherein:

[0040] The scraper includes:

[0041] At least one pair of scraping blades, each pair is symmetrically arranged in the radial direction of the rough boring head body;

[0042] The top block 30 is located at the center of the rough boring head body and has a tapered structure, and the corresponding tapered surface is supported by the centripetal end of the scraper;

[0043] The reset device is located between each pair of paired scraping knives for its reset; it is reset by pressing the spring installe...

Abstract

The invention discloses an automatically expanding and shrinking scraping-rolling combined deep hole cutter. A scraping part of the cutter comprises at least one pair of scrapers, a top block, and a reset device; the top block is positioned in the centre of a thick boring head body and is provided with a taper structure, and a corresponding conical surface is jacked by an endocentric end of the scraper; and the reset device is arranged between each matched pair of scrapers for resetting the scrapers; and a rolling part of the cutter comprises a rolling path and a keeper. The combined boring head also comprises a manipulating device which comprises a first driving part and a second driving part, wherein the first driving part drives the keeper to move axially along a spindle, and the second driving part penetrates a centre hole and acts on the top block in order to drive the top block to move axially along the spindle. The cutter disclosed by the invention is compact in structure, high in processing precision, convenient to use, and can expand and shrink automatically.

Description

technical field [0001] The invention relates to a combined deep hole cutter with an automatic expansion and contraction mechanism of a deep hole boring-scraping-rolling composite cutter, which is beneficial to the retraction of the cutter during deep hole processing or after processing. Background technique [0002] At present, most deep hole machining uses a single tool. Even if the boring and rolling compound tool is used, the automatic expansion and contraction function of the tool cannot be realized. Because the tool shaft of the deep hole machining tool is very long, the tool has natural deflection deformation and poor stability. The tool is very easy to scratch the machined surface when the tool is retracted in the middle of the work process or the workpiece is retracted after processing. When the tool is damaged or the machine tool is stopped midway during the processing of the workpiece, the tool will return to the damaged workpiece and the workpiece will be scrapped...
