Abstract
The utility model relates to a porous boring tool which comprises a boring bar, tool bits and fasteners and is characterized in that at least two through-holes and threaded holes corresponding to the through-holes are formed on the boring bar, wherein the axial positions of the through-holes are defined by the dimensions of the workpiece to be machined; the tool bits are fastened in the through-holes by the fasteners; the axial positions of the threaded holes on the boring bar correspond to the through-holes one to one; each threaded hole is mutually perpendicular to the corresponding through-hole; and the cutting sizes of the tool bits are sequentially and incrementally increased from the head part of the boring bar to the tail part thereof. The porous boring tool has the following advantages: by mounting a plurality of tool bits on one boring bar, the porous boring tool is capable of machining a plurality of geometric machining surfaces of a stepped hole each time of cutting and chamfering sharp corners; the machining efficiency can be improved; furthermore, since the plurality of geometric machining surfaces are machined at the same time of cutting, the coaxiality and straightness of the geometric machining surfaces are higher, thereby improving the machining quality of products.
Description
Technical field
The utility model belongs to the machine tool field, particularly relates to a kind of porous boring cutter.
Background technology
Part is in mechanical processing process, and boring processing shoulder hole and the wedge angle that needs chamfering occur through regular meeting.At present, have only a cutter that part is processed on the boring bar, and form how much machined surfaces.Process a plurality of geometric surfaces if desired, must repeatedly process boring cutter with many, working (machining) efficiency is lower.Owing to use different boring cutters repeatedly to process, will inevitably cause axiality and linearity between each shoulder hole to reduce, influenced the crudy of product.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, working (machining) efficiency is high and the porous boring cutter of a plurality of geometric surfaces of processing shoulder hole simultaneously.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The porous boring cutter comprises boring bar, cutter head and securing member, it is characterized in that: have two through holes and the screwed hole corresponding with through hole that are limited its axial location by the processing work size on the described boring bar at least, be fastened with cutter head by securing member in each through hole.
The utility model can also adopt following technical scheme:
Have three through holes on the described boring bar.
The afterbody of described boring bar is shaped on platform.
The axial location of described boring bar upper screwed hole and lead to the hole site are one to one, each screwed hole and pairing through hole and orthogonal.
The cutting size of described cutter head is that head to the afterbody by boring bar increases progressively successively.
Described securing member is soket head cap screw and fastening jackscrew.
Advantage and the good effect that the utlity model has are: after the utility model has adopted above technical scheme, and by on a boring bar, a plurality of cutter heads being installed, a plurality of how much machined surfaces that a feed just can processing shoulder hole, and can carry out chamfering to wedge angle; Not only improved working (machining) efficiency, and because a plurality of how much machined surfaces are to obtain by processing with a feed, the axiality and the linearity of each how much machined surface are higher, have improved the crudy of product.

The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 to Fig. 5, a kind of porous boring cutter, comprise boring bar 1, cutter head a2, cutter head b3, cutter head c4 and securing member, have three through hole 1-2 and screwed hole 1-3 on the described boring bar 1, position to axial between each through hole 1-2 is limited by the size of workpiece to be machined, be fastened with cutter head by fastening jackscrew 5 or soket head cap screw 6 in each through hole 1-2, the afterbody of boring bar 1 is shaped on platform 1-1.Axial location and the through hole 1-2 of boring bar 1 upper screwed hole 1-3 are one to one, and each screwed hole 1-3 and pairing through hole 1-2 are mutually perpendicular.The size of respectively cutting of cutter head a2, cutter head b3 and cutter head c4 is that head to afterbody by boring bar 1 increases progressively successively.
Operating principle of the present utility model is:
Elder generation in the through hole 1-2 of boring bar 1, is fixed with fastening jackscrew 5 and soket head cap screw 6 each cutter head difference insert again with each cutter head, the cutting size of each cutter head is increased successively by head to the afterbody of boring bar 1, can realize the cutting of how much machined surfaces in different apertures.
Claims (6)
