Description
Technical field
The utility model relates to a kind of rose reamer, processes each Hole chamfering Combined type chamfering cutter more specifically to one.
Background technology
Many machine components all need machining hole, and hole generally all needs to use rose reamer chamfering, and such as, certain cylinder part shown in Fig. 2, needs each hole machined chamfering.Existing rose reamer is made up of handle of a knife and cutter head, and handle of a knife and cutter head are integral structure.Under existing structure, on the one hand, if because of chamfering demand difference need change cutter head, then must entirety change; On the other hand, because retaining part is identical with rose reamer tool bit part diameter, cutter hub toughness is poor, and the location-appropriate when carrying out chamfer machining not easily according to hole leads, to so far, market lacks a kind of Combined type chamfering cutter adapting to shaft core position deviation between cutter head and hole.
Pass through patent retrieval, it is open that rose reamer about machining hole chamfering has correlation technique, as Chinese Patent Application No.: CN201220471764.5, the applying date: on September 17th, 2012, invention and created name is: a kind of chamfering tool, and this application case discloses a kind of chamfering tool, comprises rose reamer and pull bar, rose reamer is provided with centre bore, and pull bar to insert in centre bore from the small end of rose reamer and is solidly connected integral; Pull bar is also provided with the operating grip of flexible connection; The chamfering of rose reamer is 45 degree ~ 60 degree.This application case structure is simple, making is easy, and easy to operate, the pull bar of rose reamer passes back through from the back side of flange mounting hole, avoids the restriction of hemi-closure space to operation, the steady quality of product.Its weak point is: pull bar and rose reamer are fixed with one, and cannot dismantle, and change cutter head and just need integral replacing, cause use cost higher; Secondly, because the cutter head of each model is fixed with knife bar, deposit this rose reamer and can occupy large quantity space.
In addition, Chinese Patent Application No. CN201120088086.X, the applying date: on March 30th, 2011, invention and created name is: a kind of brill spot-facing plug-in mounting gang tool, this application case discloses a kind of brill spot-facing plug-in mounting gang tool, comprise drill bit and counterbit, drill bit and counterbit are split-type structural, and drill bit and counterbit are installed together; Also comprise drill bushing, drill bit and counterbit are sleeved in drill bushing by drill bushing; Counterbit is fixed on drill bit by holding screw or pin by described drill bushing; Described counterbit is white steel knife.It is more convenient that this kind bores the dismounting of spot-facing plug-in mounting gang tool, can any portion flexibly more in bit change or counterbit, to maintain a whole set of normal use of boring spot-facing cutter; Also meet various spot-facing process requirements by changing counterbit.Its weak point is: drill sleeve is in counterbit cover, and thus bit diameter must be less than drill bushing, causes the pliability of whole drill body poor, is unfavorable for the position deviation of the adaptation hole heart, and the Hole chamfering obtained is uneven, unsightly; Secondly, drill bit utilizes many pieces of holding screws to fix between drill bushing, easily weares and teares and fixing inconvenience.
