Abstract
The utility model relates to a combined cutting tool for keywaying. A cutter bar is arranged on the combined cutting tool; a plurality of keyway cutters are mounted on the cutter bar; each keyway cutter is mounted and fixed in a corresponding slot in the cutter bar through a fastening bolt and a wedge block; the contact length between the cutting edge of each keyway cutter and a workpiece is shorter than 10 mm; the wedge block is fixed by an inner hexagon screw; and the inner hexagon screw pulls the wedge block to clamp the keyway cutters. The contact area between the cutting edge of the keyway cutter and the workpiece is greatly reduced, so that the phenomena of cutter shocking, shunning and the like are avoided, the processing quality of the workpiece is improved, and the service life of a machine tool is prolonged; and the combined cutting tool has the advantages of simple structure and low cost, and is convenient for operation and use, thereby being particularly suitable for processing keyway bolts with the keyway widths equal to or larger than 16 mm.
Description
Technical field
The utility model relates to a kind of gang tool, specifically a kind of keyway latch processing gang tool.
Background technology
We know, at present, process keyway on wheel hub, and commonly used have two kinds of methods: the one, on broaching machine with broaching tool broaching, broaching tool cost height; The 2nd, slotting on slotting (plane) bed, the keyway cutter is made simple, but keyway cutter cutting edge and workpiece contact width are big, keyway that can only slotting width of keyway≤14mm, when the keyway of slotting width of keyway 〉=16mm will occur shaking cutter, keep away phenomenons such as cutter, influence workpiece crudy and lathe life-span.At present, be not used for processing the special combination cutter of 16mm≤width of keyway≤28mm on the market.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy to use, flexible, keyway processing gang tool with low cost.It is applicable to the keyway of slotting processing width of keyway 〉=16mm.
The technical scheme in the invention for solving the above technical problem is: a kind of keyway processing gang tool, it is provided with a knife bar, it is characterized in that: be equipped with some on the knife bar the keyway cutter, every the keyway cutter is fixed on the knife bar in the corresponding groove by trip bolt and voussoir, keyway cutter cutting edge and workpiece contact length are less than 10mm.
The said voussoir of the utility model is fixed by soket head cap screw, and soket head cap screw pulling voussoir clamps the keyway cutter.
The utility model is owing to adopt said structure, be equipped with somely on one knife bar, against existing technologies, every keyway cutter cutting edge and workpiece contact area significantly reduced the keyway cutter, avoid occurring the shake cutter, keep away phenomenon such as cutter, improved workpiece crudy and lathe life-span.The utility model is simple in structure, and is cheap, easy for operation, and the keyway latch processing that is specially adapted to width of keyway 〉=16mm is used.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Label among the figure is: 1. keyway cutter, 2. knife bar, 3. trip bolt, 4. soket head cap screw, 5. voussoir.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further: utilize trip bolt to fix the keyway cutter,
As can be seen from Figure 1, a kind of keyway processing gang tool, it is provided with a knife bar 2, it is characterized in that: be equipped with some on the knife bar 2 keyway cutter 1, every keyway cutter 1 is fixed on the knife bar 2 in the corresponding groove by trip bolt 3 and voussoir 5, keyway cutter 1 cutting edge and workpiece contact length are less than 10mm.It is every keyway cutter 1 to utilize trip bolt 3 to fix, and many cutting edges the keyway cutter are positioned on the same basal plane.
The said voussoir 5 of the utility model is fixing by soket head cap screw 4, and soket head cap screw 4 pulling voussoirs 5 clamp keyway cutter 1.
When the utility model used, many cutting edges the keyway cutter were in same basal plane, when the slotting machine ram moves down slotting, by many keyway cutter are finished the deep processing of the each feeding keyway of lathe jointly.Every keyway cutter cutting edge and workpiece contact area are significantly reduced, avoid occurring the shake cutter, keep away phenomenon such as cutter, improved workpiece crudy and lathe life-span.The utility model is simple in structure, and is cheap, easy for operation, and the keyway latch processing that is specially adapted to width of keyway 〉=16mm is used.Reduced the contact area of cutting edge and workpiece.
Claims (2)
1. a keyway is processed gang tool, it is provided with a knife bar, it is characterized in that: be equipped with somely the keyway cutter on the knife bar, every the keyway cutter be fixed on the knife bar in the corresponding groove by trip bolt and voussoir, keyway cutter cutting edge and workpiece contact length are less than 10mm.
2. keyway processing gang tool according to claim 1, it is characterized in that: said voussoir is fixed by soket head cap screw, and soket head cap screw pulling voussoir clamps the keyway cutter.
