Abstract

The slotting cutter of able to transpose position and to change series of bits, constitute by handle of a knife and cutter head two parts, cutter head is interchangeable, handle of a knife and cutter head connect with screw thread and adopt conical to locate, the positioning accuracy height, the cutter head front end is equipped with indexable insert tip, throw away tip, when the blade of selecting the band centre bore for use, the central screw clamping mode is adopted in the clamping of blade, when selecting blade not with holes for use, the clamping of blade is adopted and is gone up the pressure type clamping mode, blade reliable clamping, cutter head and handle of a knife all can be done typing by the different size specification and produce in batches, have reduced the tool magazine storage.

Description

The slotting cutter of able to transpose position and to change series of bits

The invention belongs to a kind of metal-cutting machine tool

This slotting cutter partly adopts spiral marking connection to form by shank portion and cutter head, it is characterized in that handle of a knife (see in accompanying drawing 1, the accompanying drawing 2 1) goes up externally threaded rear portion and have conical boss shoulder, the front portion that cutter head (see in accompanying drawing 1, the accompanying drawing 2 2) is gone up internal thread has conical concave station shoulder, both adopt conical and locate when spiral marking connection.Can obtain high orientation precision.Interchangeable cutter head is not to be with the cutter neck, and rigidity is strong, and the cutter head front end has the cutter groove.An indexable insert tip, throw away tip is housed in each cutter groove, blade clamps and adopts central screw (see in the accompanying drawing 1 3) clamping mode when blade is selected the indexable insert tip, throw away tip (see in the accompanying drawing 1 4) of band centre bore for use, promptly pass the centre bore of blade, just blade is clamped in the cutter groove when tightening screw with a screw.When selecting indexable insert tip, throw away tip not with holes (see in the accompanying drawing 2 4) for use, blade clamps to adopt goes up the pressure type clamping device, with the screw of a band mushroom head (see in the accompanying drawing 2 3) when tightening screw from top to bottom, blade is clamped in the cutter groove, perhaps adopt a little pressing plate to add a pinching screw, when tightening screw blade is clamped in the cutter groove.The method that is threaded is adopted in connection between cutter head and the handle of a knife.The front end of opening the internal thread handle of a knife at the cutter head afterbody has corresponding external screw thread, have a pair of breach that wrench is puted forth effort during for tool changing in the tail side of cutter head, the cutter head of this milling cutter can be made into the series specification of different-diameter, difference according to the tool bit diameter size, internal thread selects for use the dimensions of the standard of the varying in size handle of a knife external screw thread that adapts therewith also to make the standard specification that adapts at the bottom of the cutter head tail, the processing of this kind cutter is easy to use, be beneficial to typing seriation ground again and produce in batches, thereby can reduce the quantity in stock of cutter.

Accompanying drawing 1 is the overview of the slotting cutter of able to transpose position and to change series of bits that indexable insert tip, throw away tip with holes is housed.Among the figure, 1-handle of a knife, 2-cutter head, 3-screw, 4-indexable insert tip, throw away tip.

Accompanying drawing 2 is the overview of the slotting cutter of able to transpose position and to change series of bits that indexable insert tip, throw away tip not with holes is housed.Among the figure, 1-handle of a knife, 2-cutter head, the screw of 3-band mushroom head, 4-indexable insert tip, throw away tip.

Claims

1, the slotting cutter of the able to transpose position and to change series of bits that removably cutter head constituted of indexable insert tip, throw away tip is housed by handle of a knife and front end, it is characterized in that locating when cutter head and handle of a knife adopt conical during in thread connection, the concrete practice is that the external screw thread rear portion has on conical boss shoulder, the interchangeable cutter head internal thread front portion and has conical concave station and take on both and come positioning threads to connect with conical on the handle of a knife.Blade fixture adopts the central screw clamping mode when selecting the indexable insert tip, throw away tip of band centre bore for use, adopt when selecting blade not with holes for use and go up the pressure type clamping device.

2, the slotting cutter of the described able to transpose position and to change series of bits of claim 1 is characterized in that cutter head is magnetic tape trailer end extension body-cutter neck not.Thereby cutter head to the connection position of handle of a knife at cutter head rather than on the cutter neck.

The centre bore that passes blade with a screw when 3, the slotting cutter of the described able to transpose position and to change series of bits of claim 1 is characterized in that blade clamping mode employing central screw clamping device is tightened screw blade is clamped in the cutter groove of interchangeable cutter head front end.

4, the slotting cutter of the described able to transpose position and to change series of bits of claim 1 is characterized in that the blade clamping mode adopts the screw (also can adopt pinching screw of a little pressing plate band) that adopts a band mushroom head when going up the pressure type clamping device to tighten screw blade is clamped in the cutter groove of interchangeable cutter head front end.

5, the slotting cutter of the described able to transpose position and to change series of bits of claim 1 is characterized in that the spiral marking connection device of cutter head, handle of a knife, and internal thread is opened at the bottom of the cutter head tail, external screw thread is opened the front end at handle of a knife, the side of cutter head has a pair of breach that supplies wrench to put forth effort.
