Abstract
The present utility model relates to an arc shaped tool head fixed in a deep hole ejection drill. A larger arc is required to connect smoothly hole walls in the deep hole bottom part of a connecting rod of a diesel engine with different types in existence, then an arc shaped R cutting tool used for performing a deep hole arc connecting processing is required after a deep hole maching process by a standard cutting tool during a processing process. However, such an arc R type cutting tool has a long manufacturing period, with expensive cost for its design and stocking. On the basis of the reality of the former deep hole drill, a novel arc R moulding tool head in accordance with the present utility model is disclosed, which comprises a peripheral cutter blade, an intermediate cutter blade and a central cutter blade, with their end surface cutting edges being in a beeline and their cutter blades being opened for a former angles, wherein the arc R of the intermediate cutter blade is connected smoothly to the that of the peripheral cutter blade. Therefore, a mass of assistant time is saved, and the working load of a machine tool operator is reduced. The present utility model kills two birds with one stone, both resolving a processing problem and reducing the cost of a tool and a processing course.
Description
Technical field:
The utility model relates to a kind of machining tool, specifically refers to a kind of circular arc type cutter head that is installed on the spray-sucking type deep hole drill of processing draw ratio＜100.
Background technology:
The various diesel engine type connecting rod deep hole bottoms of existing product must have than orthodrome and hole wall are smooth and are connected.In traditional process, use the standard cutter deep hole processing after, also need dispose the cutter that is used for the deep hole processing circular arc and carry out circular arc and connect processing, exist the manufacturing cycle long, and design, buying expenses are big.
Summary of the invention:
The utility model exists for solving above-mentioned existing machining tool: after using the standard cutter deep hole processing, also need dispose and be used for the deep hole processing round tool and carry out circular arc and connect the repeatedly deficiency of processing, a kind of cutter that needs time processing proposed, reach the processing characteristics requirement when the deep hole of processing draw ratio＜100, good as impact resistance, and take into account the circular arc type blade of the spray-sucking type deep hole drill that can directly be installed on processing draw ratio＜100 of its wearability.
The type of boring by the standard deep of former configuration can be divided into be used for the aperture less than ￠ 60 and aperture greater than ￠ 60 deep hole machining two big classes.But the depth drill that the deep hole of aperture＜￠ 60 adopts is the monoblock type cutter sharpening type, therefore, the periphery Sharpening a knife blade of drill body is become circular arc R shape, and the end face cutting edge of sharpening intermediate blades and center insert and periphery blade can satisfy processing request again.
The utility model is primarily aimed at aperture 〉=￠ 60 deep holes, proposes following technical solution:
For the connecting rod deep hole of aperture 〉=￠ 60, its pass requires shown in accompanying drawing 2-2, because the aperture is big, so use unit-type drill head body form adjustable as carbide chip.Therefore, can utilize the cutter hub of primary standard drill body and periphery blade and intermediate blades and center insert that must the moulding of new design circular arc R.The end face cutting edge of intermediate blades and center insert and periphery blade and is connected with the circular arc R of periphery blade is smooth in a straight line, and the blade of intermediate blades and center insert and periphery blade is all opened anterior angle.
All utilizing former using on the basis of drill bit in view of above-mentioned improvement project, therefore, both solving processing problems and reached the purpose that shortens the process-cycle, the instrument of saving again kills two birds with one stone just.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described
A kind of circular arc type cutter head that is installed on deep hole spray suction brill, its by drill body 1 with drill body 1 on be connected the cutter head that constitutes by intermediate blades 111 and center insert 112 and periphery blade 113 through screw, the arc radius R of its periphery blade 113 is 0～10m (shown in accompanying drawing 1,2-1,2-2,4).
Described circular arc type cutter head, end face cutting edge of blade 111 and center insert 112 and periphery blade 113 is on a 160-180 ° of straight line in the middle of it, and be connected with the circular arc R of periphery blade 113 is smooth, the blade of intermediate blades 111 and center insert 112 and periphery blade 113 is opened anterior angle 5-10 °.The depth drill that shown in the accompanying drawing 4 is aperture=￠ 60 improves blade assembly structure schematic diagram.
A most preferred embodiment of the present utility model is an example with ￠ 60 depth drills, and through carefully measuring, considering, the design improvement blade is shown in accompanying drawing 3-2.The end face cutting edge of blade 111 and center insert 112 and periphery blade 113 is on 180 ° of one straight line in the middle of it, and is connected with the circular arc R of periphery blade 113 is smooth, and the blade of intermediate blades 111 and center insert 112 and periphery blade 113 is opened 6 ° of anterior angles.
The requirement of consideration blade impact resistance in the bigger deep hole machining of draw ratio, blade comprise that promptly intermediate blades 111 and center insert 112 and periphery blade 113 materials all adopt YT798.
In sum, in the utility model design, at the deep hole of aperture 〉=￠ 60 and voluntarily the blade of design not only cuts brisk, satisfy the product drawing requirement, and do not need to dismantle the former the Knife tool of using after the deep hole machining in the first time, only need on former drill body, to change R type blade and can carry out R circular arc connection processing, saved a large amount of non-cutting times especially, alleviated machine operation personnel's live load greatly.
