Description

Drilling and countersinking milling integrated cutter shaft

Technical Field

The utility model relates to a lathe cutter equipment technical field, concretely relates to drilling, mill integrative arbor of counter sink.

Background

Along with the continuous upgrading and transformation of modern machining technology, the type and the application field of cutter are also continuously expanding, and traditional machining cutter also can not satisfy the processing requirement of modern automatic nonstandard piece, and mainly machining efficiency is low, and the cost consumption is higher, and bad product rate is equally more, for example: the existing workpiece plate needs to be drilled, and a countersunk hole is machined under the concentric and coaxial condition, the traditional machining mode of the machine tool is that the hole is drilled firstly, and then the tool is changed to a hole milling tool for machining, so that the machining and manufacturing efficiency is influenced by the support of two stations and a plurality of procedures.

Disclosure of Invention

The utility model discloses the purpose is: aiming at the technical requirements of improving the processing and manufacturing efficiency and quickly and efficiently processing a countersunk hole on a workpiece in the background technology, the integrated cutter shaft for drilling and milling the countersunk hole is designed, the workpiece is drilled on the same cutter shaft by means of the combination of a drilling cutter and a milling cutter, the countersunk hole is synchronously milled, the cutter changing and re-tool setting are not needed, and the integrated cutter shaft is practical and efficient.

The technical scheme adopted for solving the problems is as follows:

an integrated cutter shaft for drilling and milling a counter bore comprises a cutter handle, a cutter holder, a jaw assembly, a milling cutter blade and a drilling cutter which are fixedly connected integrally,

the jack catch component consists of a chuck body, movable jack catches and a jack catch driving mechanism, the whole body is of a multi-jaw chuck structure, the inner side surfaces of the centers of the jack catches inwards clamp the drill tool handles of the drill tools, the outer vertical side surfaces of the jack catches are fixedly connected with milling cutter blades through screws, the front cutter surfaces at the bottoms of the milling cutter blades are all horizontally coplanar,

the drill comprises a drill handle and a drill bit, the outer diameter of the drill bit is larger than that of the drill handle, and the radius difference between the drill bit and the drill handle is slightly larger than the distance between the vertical cutting surface of the milling cutter blade and the drill handle.

Furthermore, the radius difference between the drill bit and the drill tool handle of the drill tool selected according to different countersunk hole machining requirements is constant.

Further, the distance from the outer side surface of the claw to the central axis is smaller than the distance from the front cutter head of the milling cutter blade to the central axis.

Furthermore, the rotating direction of the cutter handle is consistent with the normal direction of the milling cutter blade fixed on the outer vertical side face of the clamping jaw.

The utility model has the advantages that:

this integrative arbor of drilling, milling counter bore is with the help of the mode that drilling tool and milling cutter combined together, implements drilling to the work piece on same arbor to the counter bore is milled in step, and changes drilling tool or milling cutter piece according to the specification difference of waiting to process the counter bore, need not to change drilling machine and milling machine and tool setting operation, and is practical high-efficient.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-4, the present embodiment provides an integrated arbor for drilling and milling a countersink, which includes a tool shank 1, a tool holder 2, a jaw assembly, a milling blade 7, and a drill 6, which are integrally connected.

Specifically speaking, the jack catch subassembly comprises chuck body 4, movable jack catch 5 and jack catch actuating mechanism 3, wholly is multi-jaw chuck structure, 3 the drill cutter handle of a

knife

62, 3 of jack catch 5's the inside centre medial surface centre gripping drill cutter 6 the outer side of standing of jack catch 5 has linked firmly milling cutter piece 7 through screw 8, the equal level coplane of rake face bottom milling cutter piece 7.

The drill 6 comprises a drill handle 62 and a drill bit 61, the outer diameter of the drill bit 61 is larger than that of the drill handle 62, and the radius difference between the two is slightly larger than the distance between the vertical cutting surface of the milling cutter blade and the drill handle.
