Abstract

A combined cutting tool for machining deep holes in high-requirement metal is composed of boring cutter, reamer, extruding guide cutter, cutter rod, connecting tube and cutter handle. The boring cutter, the reamer and the extrusion guide cutter are sequentially welded on the cutter bar; the cutter bar, the connecting pipe and the cutter handle are welded and connected in sequence to form the combined cutter. The inclination angle alpha of the edge of the boring cutter is 5-25 degrees; the ratio of the diameter to the length of the combined cutter is 1: 15-20; the diameter size range is phi 12 mm-phi 48 mm. The cutter can process the drilled deep hole at one time with high requirement.

Description

A kind of gang tool

Technical field

The utility model relates to a kind of gang tool in metal deep hole machining field.

Background technology

At present, to the processing of high request metal deep hole, generally all be to take earlier with the good deep hole of bit drills; Then deep hole is carried out right boring with boring cutter; Finish ream with reamer again, carry out honing or rolling and processing at last again and handle, finally obtain the metal deep hole of high request.This processing method, the cutter of use and machine-tool kind are many; Need multiple clamping workpiece and cutter, inefficiency, the machining accuracy of workpiece is difficult to be guaranteed.

Summary of the invention

Present high request metal deep hole machining technology is loaded down with trivial details in order to overcome, processing inefficiency, metal deep hole precision are difficult to guaranteed drawback, the gang tool that the utility model provides a kind of high request metal deep hole machining to use.This gang tool once just can be finished the metal deep hole machining of high request on the basis of boring the metal deep hole, not only simplified processing technology, has improved the processing work efficiency, and has guaranteed the machining accuracy of high request metal deep hole.

The technical scheme that its technical problem that solves the utility model adopts is: gang tool is combined by boring cutter, reamer, extruding guiding cutter, knife bar, adapter, handle of a knife.Boring cutter, reamer, extruding guiding cutter are welded on the knife bar successively, and boring cutter is preceding; Knife bar, adapter, handle of a knife weld successively and are connected into gang tool.On knife bar, be drilled with cooling fluid turnover through hole, on handle of a knife, be drilled with cooling fluid and enter the hole; Boring cutter cutting edge inclination α in the gang tool is 5 °～25 °, guarantees to flow before the cutting metal cutter bits in the cutter process; Extruding guiding cutter one is to improve the deep hole inside surface roughness, the 2nd, can play the guiding role to gang tool, and guarantee that deep hole machining directly spends; The diameter of gang tool and length ratio are 1: 15～20; The diameter range of gang tool is φ 12mm～φ 48mm.

The specific embodiment

The utility model is described in further detail below with reference to Fig. 1.

In Fig. 1, form gang tool by boring cutter (1), reamer (2), extruding guiding cutter (4), knife bar (3), adapter (5), handle of a knife (8).Boring cutter (1), reamer (2), extruding guiding cutter (4) are welded on the knife bar (3) successively, and boring cutter (1) is preceding, and reamer (2) is placed in the middle, extruding guiding cutter (4) after; Knife bar (3), adapter (5), handle of a knife (8) weld successively and are connected into gang tool integral body.On knife bar (3), be drilled with cooling fluid turnover through hole (6); Be drilled with cooling fluid and enter hole (7) on handle of a knife (8), handle of a knife (8) can be installed on the unsteady self-centering chuck of machine-tool; The cutting edge inclination α of the boring cutter in the gang tool (1) is 5 °～25 ° a angle; The diameter of gang tool and length ratio are 1: 15～20; The diameter of gang tool is φ 12mm～φ 48mm.

Claims

1. a gang tool is made up of boring cutter, reamer, extruding guiding cutter, knife bar, adapter, it is characterized in that: boring cutter, reamer, extruding guiding cutter are welded on the knife bar successively, and boring cutter is preceding; Knife bar, adapter, handle of a knife weld successively and are connected into gang tool, are drilled with cooling fluid turnover through hole on knife bar; On handle of a knife, be drilled with cooling fluid and enter the hole.

2. a kind of gang tool according to claim 1 is characterized in that: the cutting edge inclination α of boring cutter is 5 °～25 °.

3. a kind of gang tool according to claim 1 is characterized in that: the diameter of gang tool and length ratio are 1: 15～20.
