Abstract
The utility model discloses a special cutter tool for hole enlarging. A section of guiding cylinder is arranged on the front end of the expanding chip cutting edge on the cutter rod; the external circle diameter of the guiding cylinder is smaller than external circle diameter of the expanding chip cutting edge; the cylindrical surface of the guiding cylinder is also provided with a chip guiding groove, and the upper part of the expanding chip cutting edge on the cutter rod is also provided with a cavity cutting chip cutting edge. When the utility model proceeds the hole expansion, the guiding cylinder can firstly enter into the clamping apparatus guiding hole on the lower part of the processed part hole, and accordingly, the working strength and the stability of the whole cutter can be reinforced, and the irregular acting force to the main shaft of the machine tool can be alleviated in the radial direction. Accordingly, the utility model has the advantages of higher expanding processing precision and stable and reliable processing quality; the vibration generated by the main shaft of the machine tool is not easy to occur, and the rotating precision of the main shaft of the machine tool can overcome the influence to the position degree of the parts. The utility model is specially suitable for the hole expansion of the processing thin plate type parts on the machine tool, such as: a drilling machine, a milling machine, etc.
Description
Technical field:
The utility model relates to a kind of reaming dedicated tool, and particularly a kind of reaming dedicated tool of processing sheet type metal parts belongs to the metal working tool technical field of tools.
Background technology:
At present, in the prior art during reaming of processing metal part, generally all be directly to adopt drilling cutters or milling cutter to carry out reaming, the shortcoming of this broad is: its reaming precision mainly is subjected to the influence of machining tool main shaft precision, and adding man-hour because the cutter discontinuity, be easy to cause that machine tool chief axis vibrates, thereby influence crudy; Particularly when thin plate class part is carried out reaming,, the quality in the hole of part to be processed is reduced greatly because the swing of cutter is bigger.Therefore the processing effect of existing broad still is not ideal.
Summary of the invention:
The purpose of this utility model is: provide a kind of reaming machining accuracy higher, be difficult for causing the vibrative and reliable reaming dedicated tool of stable processing quality of machine tool chief axis, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises knife bar (1) and is provided with reaming cutting edge (2) and dregs guiding groove (3) that on knife bar (1) front end of going up reaming cutting edge (2) at knife bar (1) is provided with a joint guide cylinder (4); The outside diameter of guide cylinder (4) is less than the outside diameter of reaming cutting edge (2); On the face of cylinder of guide cylinder (4), also be provided with dregs guiding groove (3); Also be provided with one on the top of the last reaming cutting edge (2) of knife bar (1) and cut down nest cutting edge (5), cut down the outside diameter of the outside diameter of nest cutting edge (5) greater than reaming cutting edge (2).
Owing to adopted technique scheme, when using the utility model reaming, its guide cylinder (4) is introduced in the anchor clamps pilot hole of below, part to be processed hole, thereby the working strength and the stability of whole cutter have been strengthened greatly, alleviated greatly the irregular active force of machine tool chief axis radial direction, therefore the utility model compared with prior art, the utlity model has the reaming machining accuracy higher, be difficult for causing that machine tool chief axis produces vibration, and can overcome influence and the stable processing quality reliable advantage of machine tool chief axis running accuracy to the part position degree; In addition, the utility model can also carry out chamfered to the periphery that expands good hole in reaming, so the utility model also has the working (machining) efficiency height, and can alleviate the advantage of labor strength and processing ease.The utility model uses when being particularly suitable on the lathes such as drilling machine, milling machine the reaming of processing sheet type part.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: the material that has the knife bar (1) of reaming cutting edge (2) and dregs guiding groove (3) can adopt milling cutter of the prior art or drilling cutters material to make, during making, produce a joint guide cylinder (4) of 10～200 millimeters long simultaneously at the front end of the last reaming cutting edge (2) of knife bar (1), the outside diameter of guide cylinder (4) is made into less than 2～20 millimeters of the outside diameters of reaming cutting edge (2), and on the face of cylinder of guide cylinder (4), also produce dregs guiding groove (3) simultaneously, produce one simultaneously on the top of the last reaming cutting edge (2) of knife bar (1) and cut down nest cutting edge (5), to cut down the outside diameter that the outside diameter of nest cutting edge (5) is made into greater than reaming cutting edge (2) and get final product for 2～15 millimeters, the outside diameter of reaming cutting edge (2) can be determined according to the diameter of the hole in piece part of required processing.
Claims (4)
