Abstract
The utility model discloses a shoulder hole processing cutter, comprises a knife handle, the one end of handle of a knife is provided with ladder sword and chip groove, the ladder sword includes the back sword that the diameter reduces in proper order, well sword and preceding sword, the terminal surface of back sword is provided with back chamfer sword, the terminal surface of well sword is provided with well chamfer sword, the terminal surface of preceding sword is provided with preceding chamfer sword, the chip groove is followed with sharp or helix form preceding sword extends to back sword sets up. Compared with the prior art, the beneficial effects of the utility model are that: the end face of each cutting part is provided with a chamfer cutting edge, chamfering processing is carried out while the hole is processed by the cutter, the process of reaming and chamfering after the hole is drilled by the traditional process is omitted, and the whole set of processing flow is completed without replacing the cutter.
Description
Technical Field
The utility model relates to the field of machinary, especially, relate to tapping cutter, especially a shoulder hole processing cutter.
Background
The composite machining tool is a rotary tool for turning or milling machining, which comprises a plurality of tool teeth. With the rapid development of modern technology, the complexity and precision requirements of part design are higher, the requirements on the smoothness and the like of the machined parts are higher, in the prior art, the machining of a composite hole with a stepped hole, a chamfer and a taper needs a plurality of cutters for machining and ensuring, each part of the composite hole needs to be well connected with each cutter to ensure the size and the appearance of the composite hole, and the machining process involves a plurality of steps and is very complicated.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome not enough of above-mentioned technique, traditional shoulder hole processing technology is complicated promptly, and the too much problem of flow provides a shoulder hole processing cutter.
In order to achieve the above object, the present invention provides the following technical solutions:
the utility model provides a shoulder hole processing cutter, includes the handle of a knife, the one end of handle of a knife is provided with ladder sword and chip groove, the ladder sword includes the back sword that the diameter reduces in proper order, well sword and preceding sword, the terminal surface of back sword is provided with back chamfer sword, the terminal surface of well sword is provided with well chamfer sword, the terminal surface of preceding sword is provided with preceding chamfer sword, the chip groove is followed with sharp or helix form preceding sword extends to back sword sets up.
Preferably, the surfaces of the step edge and the chip removing groove are provided with wear-resistant coatings.
Compared with the prior art, the beneficial effects of the utility model are that: the end face of each cutting part is provided with a chamfer cutting edge, chamfering processing is carried out while the hole is processed by the cutter, the process of reaming and chamfering after the hole is drilled by the traditional process is omitted, and the whole set of processing flow is completed without replacing the cutter.
Drawings
Fig. 1 is a schematic structural view of the stepped hole machining tool of the present invention.
In the figure: 1. a handle; 2. a rear edge; 3. a middle blade; 4. a front edge; 5. a chip removal groove; 6. a stepped edge; 21. a front chamfer edge; 31. a middle chamfer edge; 41. and a rear chamfering edge.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the embodiments of the present invention and the accompanying drawings, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
Referring to fig. 1, the present invention provides a technical solution:
the utility model provides a shoulder hole processing cutter, includes handle of a knife 1, the one end of handle of a knife 1 is provided with ladder sword 6 and chip groove 5, ladder sword 6 includes back sword 2 that the diameter reduces in proper order, well sword 3 and preceding sword 4, the terminal surface of back sword 2 is provided with back chamfer sword 21, the terminal surface of well sword 3 is provided with well chamfer sword 31, the terminal surface of preceding sword 4 is provided with preceding chamfer sword 41, chip groove 5 follows with sharp or helix form preceding sword 4 extends to back sword 2 sets up.
Preferably, the surfaces of the step edges 6 and the chip flutes 5 are provided with a wear resistant coating.
The working principle is as follows: the step blade 6 of the tool is used for processing a step hole of a product, and the step blade 6 is arranged in a third stage, so that a second-stage or third-stage step hole can be directly processed; the scraps generated during processing exit from the periphery of the cutter through the scrap discharge groove 5, so that the holes are prevented from being blocked by the scraps; during machining, the chamfering edges arranged on the end faces of the edge parts simultaneously chamfer the edges of the stepped holes, and the process of opening holes and chamfering is finished when the cutter is withdrawn; the coated wear resistant coating makes the tool of the present invention more durable.
