The machining function answered, the switching between cutter is completed by knife tower conversion station.For the relative complex special spiral shell of manufacturing procedure
Line product, a process is often changed in this single blade processing will need tool changing, and be limited by centre numerically controlled lathe cutter spacing quantity
Make and frequently change cutter spacing and bring mechanical wear and failure, so as to increase product size trueness error in process,
The stability of product is have impact on, and frequently changes cutter spacing, cutter in process, wastes substantial amounts of process time, is dropped
Low production efficiency.
The content of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of special buckle processing composite cutter
Bar, it is researched and developed primarily directed to the processing of petroleum pipeline industry special thread, is installed on a tool rest and is combined with three kinds
The blade of different model, the model of blade and setting angle are selected according to the particularity of special thread product and machining angle,
The reasonable Arrangement of tool position.
The technical solution of the utility model is：A kind of special buckle processing composite knife bar, including a tool rest, one end of tool rest
Portion is the forge piece of step type structure that is made up of three stage ranks, be separately installed with the tool rest at the end boring Boring cutter, a planar end surface knife and
One turning knife, boring Boring cutter are arranged on the bottom step of trapezium structure, and planar end surface knife is arranged on the centre of trapezium structure
On step, because flush end machining stress is relatively large, but thickness of cutting is generally less than 10mm, easily produces during turning and shakes
Dynamic, so it is optimum position to be arranged on centre, turning knife is arranged on the top step of trapezium structure, mainly due to outer
Circle processing capacity is big, and feeds larger, this position arrangement of turning knife, it is ensured that stability is higher, can give full play to dise knife and add
Work amount is big, many advantages of efficiency high, good economy performance；It is cornerwise that boring Boring cutter and turning knife are separately mounted to tool rest one
Both ends, planar end surface knife are arranged on the middle position of tool rest end.
The further technical scheme of the utility model is：The processing bore diameter scope of boring Boring cutter is 50-340mm, boring
Hole depth is not more than 40mm.
Further, the distance between point of a knife of the point of a knife of boring Boring cutter and planar end surface knife a=40-45mm, the bore hole of processing is made
Aperture minimum can reach 50mm.
Further, the distance between point of a knife of the point of a knife of turning knife and planar end surface knife b=40-45mm, is to ensure boring
During below Boring cutter working depth 40mm workpiece, interference will not be produced.
Further, boring Boring cutter uses diamond shaped insert.
Further, planar end surface knife uses diamond shaped insert.
Further, boring Boring cutter and planar end surface knife correspond to respectively is no less than two matching used mounting assemblies, installation group
Part includes locking part and mounting hole, is easy to boring Boring cutter and planar end surface knife according to process requirements Reasonable adjustment position.
Further, locking part is sunk screw, and mounting hole is the screwed hole being arranged on tool rest, and easy for installation, position is steady
It is qualitative also higher.
Further, direction where the cutter head of boring Boring cutter and planar end surface knife is not parallel, avoids producing interference during cutting.
Further, the direction where the cutter head of boring Boring cutter and the acute angle that horizontal direction is formed are 95 °, the knife of planar end surface knife
The acute angle that direction where head is formed with horizontal direction is 95 °, and the setting processing effect of this position is best.
The utility model has following features compared with prior art：The utility model is primarily directed to petroleum pipeline industry
The processing of special thread and research and develop, on a tool rest installation be combined with the blades of three kinds of different models：Boring Boring cutter, flush end
Face knife and turning knife, the model of blade and established angle can be selected according to the particularity and machining angle of special thread product
Degree, it is not necessary to cutter spacing is frequently changed, it is both higher beneficial to the precision for ensureing product, it is beneficial to save process time again, adds beneficial to improving
Work efficiency rate；And the reasonable Arrangement of three kinds of blade positions of the present utility model, processing efficiency, the knife of every kind of blade can be given full play to
The piece life-span, ensure it is non-interference during the cutting of each cutter spacing, beneficial to ensureing being smoothed out for process.
Detailed construction of the present utility model is further described below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in drawings：A kind of special buckle processing composite knife bar, including a tool rest 1, the one end of tool rest 1 is by three ranks
