Combination turning process tool

Technical field

The utility model relates to a kind of machined cutter, relates in particular to a kind of combination turning process tool that is applicable to the big cutting output groove of car system.

Background technology

Turning processing is one of processing mode the most basic in the machine components processing, is used for the processing of the multiple planforms such as cylindrical, endoporus, end face, fluting, cut-out, tapping of workpiece.But for the situation that needs the annular groove of the big cutting output of car system on some product members, adopt existing turning cutting tool then can not produce a desired effect, as for width greater than 15mm and the annular groove of certain depth is arranged, adopt single lathe tool processing, the cutting force that the blade of broad bears is big, and efficient reduces, and very easily collapses cutter, serious wear, crudy is poor.

The utility model content

Main purpose of the present utility model is at the problems referred to above, and a kind of combination turning process tool is provided, and by multitool processing, reaches decomposition cutting force, raises the efficiency, and reduces cutter load and tool damage rate, improves the effect of product processing quality.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of combination turning process tool, comprise the lathe tool that constitutes by cutter hub and cutter head, it is characterized in that being provided with knife rest, described knife rest is the cylinder table shape, cylinder table one end face is provided with connecting axle, along mutually perpendicular two diameters on the cylinder table end face four axial notches are set on the face of cylinder, four described lathe tools are provided with fixing respectively crouching in opposite directions with its cutting edge and rotational workpieces packs in each groove, or two described lathe tools are provided with fixing respectively for sleeping in packing in opposite directions with its cutting edge and rotational workpieces and are arranged in two grooves of same diameter; Corresponding with the width of the annular groove of processing, the cutter head of each lathe tool stretches out cylinder table other end and so that its turning track neighboring edge reduplicative forms is fixedly installed on the position of corresponding different cylinder table radius surfaces in the groove, and the length that the cutter head from the cutter head of corresponding annular groove inside edge to corresponding annular groove outer ledge stretches out increases by an increment successively.

The increment that the length that described cutter head stretches out increases successively is 0.1mm-0.3mm; The width of described each cutter head cutting edge is 3mm-5mm, and the width of the cutting edge of the cutter head corresponding with the outer ledge of annular groove is narrower than the cutting edge of other lathe tools.

The beneficial effects of the utility model are: the hilted broadsword processing of big cutting output annular groove in the prior art is decomposed into four blade processing, the length that the cutter head of four lathe tools stretches out increases by an increment again successively, not on same plane, during work, the cutter head of four lathe tools is contact workpiece successively, can reduce the vibration of cutter hub greatly and reach decomposition cutting force, raise the efficiency, reduce the effect of cutter load and tool damage rate.

Description of drawings

Fig. 1 is the main TV structure schematic diagram of the combination turning process tool of four lathe tool structures;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the structural representation that the combination turning process tool of four lathe tool structures is applied to groove processing.

Among the figure: 11～14 lathe tools, 2 knife rests, 21～24 grooves, 3 connecting axles, 4 soket head cap screws, 5 workpiece, 51 annular grooves.

Below in conjunction with drawings and Examples the utility model is described in detail.

The specific embodiment

Embodiment 1

Fig. 1～Fig. 2 illustrates a kind of combination turning process tool of four lathe tool structures, and Fig. 3 is the structural representation that this cutter is applied to annular groove processing.This cutter comprises the lathe tool that is made of cutter hub and cutter head, it is characterized in that being provided with knife rest 2, above-mentioned knife rest is the cylinder table shape, cylinder table one end face is provided with connecting axle 3, along mutually perpendicular two diameters on the cylinder table end face four

axial notches

21,22,23,24 are set on the face of cylinder, four above-mentioned

lathe tools

11,12,13,14 are provided with in the fixing respectively groove 21,22,23,24 of packing into for sleeping in opposite directions with its cutting edge and rotational workpieces, and by soket head cap screw 4 lockings; Corresponding with the width of the annular groove of processing 51, the cutter head of each

lathe tool

11,12,13,14 stretches out the cylinder table other end also so that its turning track neighboring edge reduplicative forms is fixedly installed on the position (referring to Fig. 2) of corresponding different cylinder table radius surfaces in the groove, and cutter head 11 from the cutter head 14 of annular groove 51 inside edges of corresponding workpiece 5 to corresponding annular groove 51 outer ledges, the length that four cutter heads stretch out increases an increment (referring to Fig. 1) successively, and the increment that the length that cutter head stretches out increases successively is 0.1mm-0.3mm; The width of above-mentioned each cutter head cutting edge is 3mm-5mm, and the width of the cutting edge of the cutter head 11 corresponding with the outer ledge of annular groove 51 is narrower than the cutting edge of other three lathe tools.
