Abstract

The utility model discloses a blind hole boring cutter structure, it includes cutter arbor, blade holder and blade, cutter arbor one end overhang be connected with the blade, the cutter arbor other end and blade holder fixed connection, the cutter arbor inside with the blade holder inside all be equipped with chip removal passageway and cutting fluid pipeline, the cutting fluid pipeline in chip removal passageway top, inside chip removal passageway and the cutting fluid pipeline of cutter arbor communicates with inside chip removal passageway and the cutting fluid pipeline of blade holder each other, the inside chip removal passage end of blade holder accesss to the external world, the inside cutting fluid pipeline end -to -end connection cutting fluid injection apparatus of blade holder, cutter arbor outside cover have the trembleuse cup. This structural design is simple, and processing is convenient, can be when the dark blind hole of cutter finish machining, provide the cutting fluid and the metal sweeps of in time discharging, and prevent the damage of machined part and cutter.

Description

A kind of blind hole boring cutter structure

Technical field

This utility model relates to a kind of intermetallic composite coating and manufactures field, specifically, relates to a kind of blind Hole boring cutter structure.

Background technology

Can be used to existing hole is entered at the widely used boring cutter of lathe metal-working industry at present Row roughing, semifinishing or polish, generally use single-blade boring cutter right boring hole when, Existing boring cutter, when the blind hole that processing through hole and the degree of depth are shallower, typically can complete processing and appoint Business, but when the blind hole that working depth is deeper, a large amount of chips of blind hole built up inside can not and Time discharge, be likely to result in blade strenuous vibration or fracture, and during processing deep blind-hole cutting fluid be not It is easily accessible inside deep hole, causes working position heat higher, it is possible that metal edge is warm The open defects such as deformation, have impact on the blind hole quality of processing, time serious, can cause workpiece not Available, even damage cutter and lathe.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of blind hole boring cutter structure, should Structure design is simple, easy to process, can be when the deep blind hole of cutter polish, it is provided that cutting fluid And discharge metal debris in time, prevent the damage of workpiece and cutter.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of blind hole boring cutter structure, it includes knife bar, tool rest and blade, described knife bar one end Jag is connected with blade, and the described knife bar other end is fixing with tool rest to be connected, described knife bar Being equipped with channel of chip removal and cutting fluid pipeline inside inside and tool rest, described cutting fluid pipeline exists Above channel of chip removal, within channel of chip removal within described knife bar and cutting fluid pipeline and tool rest Channel of chip removal and cutting fluid pipeline are interconnected, and the channel of chip removal end within described tool rest leads to The external world, the cutting fluid pipe end within described tool rest connects cutting fluid injection apparatus, described Trembleuse cup it is cased with outside knife bar.

Further, described channel of chip removal tilts 2～6 degree.

Further, described channel of chip removal inwall scribbles lubricant.

Further, described cutting fluid internal diameter of the pipeline is less than channel of chip removal internal diameter.

The beneficial effects of the utility model are: this boring cutter simple in construction, easy to process, economic effect Benefit is good；Use channel of chip removal, and vias inner walls adds lubricant, it is possible to use processing Time boring cutter rotate centrifugal force chip is discharged inside blind hole smoothly, prevent chip accumulate to cutter Tool and workpiece damage；Knife bar is cased with trembleuse cup, boring cutter deep hole processing can be avoided Time, the strenuous vibration of knife bar, it is ensured that workpiece quality.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and effect It is easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.

As it is shown in figure 1, a kind of blind hole boring cutter structure, it includes knife bar 3, tool rest 6 and blade 1, Described knife bar 3 one end jag is connected with blade 1, described knife bar 3 other end and tool rest 6 Fixing connection, described knife bar 3 is internal and tool rest 6 is internal is equipped with channel of chip removal 5 and cutting fluid Pipeline 4, the chip removal above channel of chip removal 5, within described knife bar 3 of the described cutting fluid pipeline 4 Passage 5 interconnects with the channel of chip removal 5 within tool rest 6 and cutting fluid pipeline 4 mutually with cutting fluid pipeline 4 Logical, channel of chip removal 5 end within described tool rest 6 leads to the external world, cutting within described tool rest 6 Cut liquid pipeline 4 end connect cutting fluid injection apparatus, be cased with outside described knife bar 3 two shockproof Ring 2, described channel of chip removal 5 tilts 3 degree.

During work, first blade 1 is arranged on knife bar 3, by lathe location boring cutter moved to At workpiece deep hole, opening cutting fluid injection apparatus, machine tool chief axis starts to rotate, and processes workpiece, In the course of processing, cutting fluid is injected in blade 1 and absorption surface position by cutting fluid pipeline 4, Reduce deep hole internal temperature, meanwhile, utilize the centrifugal action that boring cutter rotates, by cutting of cutting Bits are discharged outside deep hole by channel of chip removal 5, prevent chip from accumulating in deep hole.

Of the present utility model ultimate principle and principal character and this practicality have more than been shown and described Novel advantage.Skilled person will appreciate that of the industry, this utility model is not by above-mentioned enforcement Simply illustrating described in the restriction of example, above-described embodiment and description is of the present utility model former Reason, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively Planting changes and improvements, these changes and improvements both fall within claimed this utility model scope In.This utility model claims scope and is defined by appending claims and equivalent thereof.
