Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0045] Terms involved in this embodiment are explained as follows.

[0046] The rake face refers to the face of the cutter through which chips flow.

[0047] The main flank refers to the cutter face opposite to the surface (transition surface) of the workpiece being machined.

[0048] The secondary flank refers to the cutter face opposite to the machined surface of the workpiece.

[0049] The main cutting edge refers to the intersection line of the rake face and the main flank face in space.

[0050] Minor cutting edge refers to the intersecting line of the rake face and the minor flank in space.

[0051] The rake angle refers to the angle between the rake face and the base surface measured in an orthogonal plane.

[0052] The ...

The tool includes a mounting seat, a first cutter head, a second cutter head and a tool seat, the mounting seat is installed on the tool seat, the tool seat is provided with a connecting part for connecting with the tool rest of the machine tool, and the mounting seat is provided with a first installation groove, the first cutter head includes a first handle and a first blade body, the surface of the first handle includes a first positioning surface, the second cutter head includes a second handle and a second blade body, and the surface of the second handle includes a first Two positioning surfaces, the cross-sections of the first blade body and the second blade body are rectangular, and the widths of the first blade body and the second blade body are all less than the entrance width of the dovetail groove to be processed, and the surface of the first blade body includes the first cutting edge and the first blade The first cutting edge is located on the end face of the first cutter body, the angle between the first relief surface and the first cutting edge is β, and the angle between the first relief surface and the first positioning surface is β‑α , the surface of the second blade head and the second blade body includes a second cutting edge and a second relief surface.

Description

technical field [0001] The present disclosure relates to the field of mechanical processing, in particular to a cutting tool and method for a dovetail groove. Background technique [0002] When the marine mixed flow pump is suspended on the bulkhead, the seawater outside the cabin can be isolated through the sealing device at its installation place. According to the usage characteristics of the mixed flow pump, for example, the sealing device is designed with at least two stages of sealing. The primary seal is an oil pressure seal, which is in a sealed state at ordinary times (the mixed flow pump is not started), and is in a non-sealed normal state when the mixed flow pump is working; the secondary seal is a mechanical seal, which is in a sealed state at any time. The primary seal includes slide valve, drogue sleeve and O-ring. Normally, the inner cone of the slide valve is sealed by pressing the sealing ring installed on the outer cone of the taper sleeve through oil pres...
