Abstract
The utility model discloses a cutter for fraising and countering a step hole. The cutter comprises a cutter rod, a fraising cutter, a countering surface cutter, a guide mechanism and a positioning mechanism, wherein the friasing cutter is arranged at the frontmost end of the cutter rod; the countering surface cutter is arranged at the rear part of the fraising cutter; the positioning mechanism comprises a thrust bearing and a fastening component which are arranged on the cutter rod in a sleeving manner; the guide mechanism is arranged at the front end of the thrust bearing; the guide mechanism comprises a guide sleeve and an internally mounted needle roller bearing; the fastening component comprises a positioning nut and a locking nut. The cutter for fraising and countering the step hole utilizes the needle roller bearing of the guide mechanism to reduce friction force, substitutes the existing direct guide friction between the cutter rod and a lining, and greatly reduces friction force; the manual depth positioning is changed to a manner that the front end surface of the thrust bearing and the upper positioning surface of a clamp are used for controlling the depth directly; through regulating the positioning nut and the locking nut at the rear part of the thrust bearing, the requirement for the size precision of the end surface of the step hole is ensured, in addition, the quality is reliable and stable, and the cost is reduced.
Description
Technical field
The utility model belongs to Machining Technology field, particularly a kind of hinge ream stepped hole cutter.
Background technology
Exhaust manifold is the important supporting member of automobile engine exhaust system, structure has the air inlet air flue corresponding with automobile engine cylinder exhaust outlet conventionally, its inlet flange face adopts stepped hole structure, according to common process thinking, first machining hole 1 and end face 1, reprocessing hole 2 and end face 2, so just need the cutter of two different-diameters, cutter at least needs twice clamping, and clamping is time-consuming; Quality is unstable, and labour intensity is large.Application number: 201220511086.0 Chinese patent discloses a kind of brill drift tool for processing step hole, there is handle of a knife and multiple cutter head, each cutter head coaxially increases progressively distribution by diameter, the outer surface of each cutter head is provided with the edge of a knife, the cutter head root of diameter maximum connects handle of a knife, the utility model is for the brill drift tool of processing step hole, adopt the multilayer cutter head of coaxial one, without tool changing, disposablely can process needed stepped hole, saved manpower and time, but adopted this combined type step cutter, when small lot, result of use is pretty good.But because knife bar leads by lining on fixture, tool setting pole stock matter, hardness requirement are higher, and knife bar and liner wear are seriously fragile, and face size precision is affected by human factors greatly in addition, quality is unstable, so the method can not meet the quality requirement of typical products in mass production.Therefore need badly, above problem is further improved and is innovated.
Utility model content
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, provide a kind of labour intensity little, can effectively reduce costs, product quality is guaranteed, the hinge ream stepped hole cutter that life cycle is long, efficiency is high.
Realizing the technical scheme that the purpose of this utility model takes is: a kind of hinge ream stepped hole cutter, comprise knife bar, reamer, ream face cutter, guiding mechanism and detent mechanism, described reamer is arranged at knife bar foremost, described ream face cutter is arranged at described reamer rear portion, described detent mechanism comprises the thrust bearing and the tightening member that are set on described knife bar, the front end of described thrust bearing arranges described guiding mechanism, and described guiding mechanism comprises fairlead and the inner needle bearing of installing.
Described tightening member comprises setscrew nut and locking nut.
Described knife bar is Morse taper shank knife bar.
On described fairlead external diameter and fixture, lining is used in conjunction with.
Described fairlead is the double braid covering structure that inside arranges wear-resisting lining jacket layer.
The utility model is provided with at the same time on the knife bar of reamer and ream face cutter and is provided with guiding mechanism and detent mechanism, concrete, utilize the needle bearing of guiding mechanism to reduce friction, change direct original knife bar and the friction of lining guiding into needle bearing overcoat and the friction of lining guiding, because needle bearing rotates flexibly, so frictional force reduces, not only extended knife bar service life, and converted products surface quality is high; And on knife bar, be set with thrust bearing and tightening member, changing the original manual positioning degree of depth on the front end face of thrust ball bearing and fixture locating surface directly controls, setscrew nut and locking nut by regulating thrust ball bearing rear portion, thrust ball bearing lower surface is contacted with locating surface on fixture, and accurate positioning and locking, thereby ensured the requirement of shoulder hole face size precision, and reliable in quality is stable, has reduced cost.
The utility model processing dimension is stable, working (machining) efficiency is high, clamped one time has been realized the two-sided accurate processing of diplopore of stepped hole, and machined surface roughness is good and finished surface between benchmark relation steady quality, product processing cost is low, cutter is easy to manufacture, be specially adapted to batch production, can be widely used in auto parts and components manufacturing industry, there is good practicality.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment mono-
As shown in Figure 1, a kind of hinge ream stepped hole cutter, comprise knife bar 1, reamer 2, ream face cutter 3, guiding mechanism and detent mechanism, described knife bar 1 is Morse taper shank knife bar, described reamer 2 is arranged at knife bar 1 foremost, described ream face cutter 3 is arranged at described reamer 2 rear portions, described detent mechanism comprises the thrust ball bearing 4 and the tightening member that are set on described knife bar 1, described tightening member comprises setscrew nut 5 and locking nut 6, the front end of described thrust ball bearing 4 arranges described guiding mechanism, described guiding mechanism comprises fairlead 7 and the inner needle bearing 8 of installing that on external diameter and fixture, lining is used in conjunction with, the ream sword of described reamer 2 is linear, the cutting edge of ream face cutter 3 is vertical with the center line of cutter, the ream sword of described reamer 2, the cutting edge of ream face cutter 3 is set to respectively four groups.
Embodiment bis-
The difference of the present embodiment and embodiment mono-is: described fairlead 7 is the inner double braid covering structure that wear-resisting lining jacket layer is set.
In above-described embodiment, by being provided with at the same time on the knife bar of reamer and ream face cutter, guiding mechanism and detent mechanism are set, concrete, utilize the needle bearing of guiding mechanism to reduce friction, direct original knife bar and lining sliding friction are changed into the rolling friction of needle bearing and fairlead, needle bearing rotates flexibly, and friction coefficient reduces, not only extended knife bar service life, and converted products surface quality is high; And on knife bar, be set with thrust ball bearing and tightening member, changing the original manual positioning degree of depth on the front end face of thrust ball bearing and fixture locating surface directly controls, locate easier, accurate, reliable, by regulating setscrew nut and the locking nut at thrust ball bearing rear portion, thrust ball bearing lower surface is contacted, and accurate positioning and locking with locating surface on fixture, thereby ensured the requirement of shoulder hole face size precision, and reliable in quality is stable, has reduced cost.
