Abstract
The invention relates to a key groove machining combined tool which is provided with a tool rod. Multiple key groove tools are installed on the tool rod. Each key groove tool is fixedly installed in a corresponding groove in the tool rod through a fastening screw and a wedge block. The contact length of a cutting edge of each key groove tool and a workpiece is smaller than 10 mm. The wedge blocks are fixed through hex socket screws which pull the wedge blocks to clamp the key groove tools. The contact area of the cutting edge of each key groove tool and the workpiece is greatly reduced, the tool vibrating and receding phenomena and the like are avoided, workpiece machining quality is improved, and the service life of a machine tool is prolonged. The key groove machining combined tool is simple in structure, low in cost, convenient to operate and use and particularly suitable for machining key groove plugs with the key groove width larger than or equal to 16 mm.
Description
Technical field
The present invention relates to a kind of gang tool, specifically a kind of key slot bolt processing gang tool.
Background technology
We know, at present, keyway are processed by wheel hub, and conventional has two kinds of methods: one is that broaching tool cost is high with broaching tool broaching on broaching machine; Two is slotting on slotting (plane) bed, keyway cutter makes simple, but keyway cutter cutting edge and absorption surface width are greatly, can only the keyway of slotting width of keyway≤14 ㎜, when the keyway of slotting width of keyway >=16 ㎜ just there will be shake cutter, keeps away the phenomenons such as cutter, affect workpiece processing quality and lathe life-span.At present, market is not used for the Special combined cutting tool of processing 16 ㎜≤width of keyway≤28 ㎜.
Summary of the invention
Technical problem to be solved by this invention overcomes above-mentioned the deficiencies in the prior art, provides a kind of structure simple, easy to use, flexible, Combined cutting tool for keywaying with low cost.It is applicable to the keyway of shaping width of keyway >=16 ㎜.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of Combined cutting tool for keywaying, it is provided with a knife bar, it is characterized in that: knife bar is provided with some keyway cutter, often keyway cutter is fixed on knife bar in corresponding groove by trip bolt and voussoir, keyway cutter cutting edge and absorption surface length are less than 10 ㎜.
The said voussoir of the present invention is fixed by soket head cap screw, and soket head cap screw pulls voussoir to clamp keyway cutter.
The present invention, owing to adopting said structure, if a knife bar is provided with one or two keyway cutter, against existing technologies, often greatly reduces keyway cutter cutting edge and absorption surface area, avoids occurring shake cutter, keeping away the phenomenons such as cutter, improves workpiece processing quality and lathe life-span.Structure of the present invention is simple, cheap, easy for operation, and the key slot bolt processing being specially adapted to width of keyway >=16 ㎜ uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Label in figure is: 1. keyway cutter, 2. knife bar, 3. trip bolt, 4. soket head cap screw, 5. voussoir.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further: utilize trip bolt to fix keyway cutter,
As can be seen from Figure 1, a kind of Combined cutting tool for keywaying, it is provided with a knife bar 2, it is characterized in that: knife bar 2 is provided with some keyway cutter 1, often keyway cutter 1 is fixed on knife bar 2 in corresponding groove by trip bolt 3 and voussoir 5, keyway cutter 1 cutting edge and absorption surface length are less than 10 ㎜.Utilize trip bolt 3 to fix often keyway cutter 1, many cutting edges keyway cutter are positioned on same basal plane.
The said voussoir 5 of the present invention is fixed by soket head cap screw 4, and soket head cap screw 4 pulls voussoir 5 to clamp keyway cutter 1.
When the present invention uses, many cutting edges keyway cutter are in same basal plane, when slotting machine ram moves down slotting, by many, keyway cutter are completed the deep processing of lathe each feeding keyway jointly.Often keyway cutter cutting edge and absorption surface area are greatly reduced, avoid occurring shake cutter, keeping away the phenomenons such as cutter, improve workpiece processing quality and lathe life-span.Structure of the present invention is simple, cheap, easy for operation, and the key slot bolt processing being specially adapted to width of keyway >=16 ㎜ uses.Decrease the contact area of cutting edge and workpiece.
Claims (2)
