Abstract

The utility model provides a crankshaft machining cutter, including handle of a knife and the tool bit of welding at the handle of a knife, the tool bit has major flank, land and chip pocket, the chisel edge length of tool bit is 4.6mm, and the inner edge oblique angle is 30, and the land angle is 8 - 12, and the relief angle is 8 - 12, and the apex angle is 118. Utility model's crankshaft machining cutter, cutter improve the back and reduce the time of spending because of the tool changing adjustment, need not to adjust the drill bit degree of depth, can normally process after the tool changing, improve efficiency, the reduction is to the requirement of staff operation adjustment technical ability, tool changing convenient and fast behind the synthetic cutter, and the machining precision is higher, need not adjustment of size.

Description

A kind of Crankshaft Machining cutter

Technical field

The utility model relates to a kind of metal cutting tool field, particularly relates to Crankshaft Machining cutter.

Background technology

In the Crankshaft Machining process of prior art, lock with machine tool chief axis again after original cutter and tool rest lock, adopt separate type cutting tool to process, i.e. centre drill processing work centre bore, end face blade processing end face.So, the comparatively big error that the adjustment of separate type cutter not only can produce, and inconvenient operation, production efficiency is low.

Utility model content

In view of the above, the Crankshaft Machining cutter being necessary to provide a kind of and reducing mismachining tolerance, production efficiency is provided.

A kind of Crankshaft Machining cutter, comprise handle of a knife and the cutter head being welded on handle of a knife, described cutter head has major flank, land and chip pocket, the chisel edge length of described cutter head is 4.6mm, and inner edge oblique angle is 30 °, and margin angle is 8 °-12 °, relief angle is 8 °-12 °, and drift angle is 118 °.

Preferably, described margin angle is 10 °.

Preferably, described relief angle is 10 °.

Preferably, described inner edge oblique angle is 30 °

Compared to prior art, Crankshaft Machining cutter of the present utility model, reduces the time because tool changing adjustment spends, without the need to adjusting bit depth after cutter improves; Can normal process be carried out after tool changing, improve efficiency; Reduce employee's operation adjustment skill set requirements, after synthesis cutter, tool changing is convenient and swift, and machining accuracy is higher, without the need to size adjusting.

Detailed description of the invention

By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.

Incorporated by reference to consulting Fig. 1 and Fig. 2, Crankshaft Machining cutter of the present utility model, comprises handle of a knife 10 and the cutter head 20 being welded on handle of a knife 10.Described cutter head 20 has major flank 3, land 2 and chip pocket 1.The chisel edge length of described cutter head 20 is 4.6mm, and inner edge oblique angle is 25-35 °, margin angle 8 °-12 °, and relief angle 8 °-12 °, drift angle is 118 °.

As the utility model preferred embodiment, described inner edge oblique angle is 30 °, and margin angle is 10 °, and relief angle is 1 °.

Crankshaft Machining cutter of the present utility model, is that cutter is directly locked with machine tool chief axis and coordinated during installation, reduces the error produced after repeatedly coordinating, improve machining accuracy; Cutting face size and bore size are merged into same as Tool Control by centre bore process tool, size required by product, the size of setting cutter, avoid, because adjustment drill bit or end face blade cause the generation of defective products, improving quality; The time because tool changing adjustment spends is reduced, without the need to adjusting bit depth (drilling depth fixed by molding cutter) after cutter improves; Can normal process be carried out after tool changing, improve efficiency; Reduce employee's operation adjustment skill set requirements, after synthesis cutter, tool changing is convenient and swift, and machining accuracy is higher, without the need to size adjusting.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
