Description

Portable chamfering machine

Technical field

The utility model relates to beveler, in particular to a kind of Portable chamfering machine.

Background technique

Currently, people, when processing hole type parts, there are sharp burrs for the end face in hole, for convenient for following process and dress Match, the end face in hole must chamfering.

Authorization Notice No. is that the patent of CN2693383Y discloses a kind of Portable round hole chamfering machine, a kind of Portable round hole Beveler, including beveler ontology, positioned at the intrinsic power device of beveler, the rose reamer being mounted in power device and For the bearing of rose reamer positioning, power device includes electric motor, the angular wheel coupled with electric motor output shaft transmission Group, the knife bar coupled with angular wheel transmission group, the pinion gear in angular wheel transmission group connect with electric motor output shaft axis, bore Gear wheel in shape gear drive group connects with cutter spindle, and angular wheel transmission group is located at the cavity of beveler body head with knife bar It is interior；The rose reamer is located on knife bar, is equipped with deep groove ball bearing on the knife bar between gear wheel and rose reamer.In use, will Cutter head insertion needs in the hole of chamfering, and to adjust disk abutting workpiece surface, then makes rose reamer and needs chamfering Bore edges contact, and then device to hole carries out chamfering.

But it is practical can encounter the situation that hole is located on cambered surface inner wall when in use, adjustment disk will be unable to and arc at this time Face is bonded, and causes cutter head that can not insert in the hole, prevent hole is from being chamfered.

Utility model content

The purpose of this utility model is to provide a kind of Portable chamfering machines, and having can be to the excellent of the Hole chamfering in cambered surface Point.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of portable chamfering Machine, including beveler ontology, rotation is provided with tool apron on the beveler ontology, and the beveler body interior, which is provided with, to be used for The driving device of tool apron rotation is driven, is detachably provided on the tool apron for being inserted into the rose reamer needed in the hole of chamfering, The rose reamer includes drill body and drill bit, and drill body is detachably connected with tool apron, and drill bit leading portion is provided with the bite for cutting Sword is provided with chip space, the tapered Cutting trajectory of cutting blade rotary in the drill body.

Through the above technical solutions, cutting blade will be with need at this time in use, rose reamer insertion is needed in the hole of chamfering It wants the bore edges of chamfering to contact, rose reamer rotation is driven by driving device later, cutting blade will need chamfering at this time Chamfering is cut out on hole, while cutting out chamfering, clast will be easily discharged out of the hole from chip space, when avoiding accumulating a large amount of clast in hole The case where can not being discharged, can process the hole in cambered surface, together due to not needing to be bonded with cambered surface when use Hole of the sample on various shape face can be processed, it is only necessary to rose reamer is put into hole, since cutting blade rotates The shape of formation is taper, therefore can pour out chamfering in the opening in hole.

Preferably, fixation hole is provided on the tool apron, the drill body end is inserted into fixation hole, is arranged on the tool apron There is the fixing piece for being fixed on rose reamer in fixation hole.

Through the above technical solutions, since the diameter in the hole of required chamfering is different, it is therefore desirable to be replaced in chamfering different Rose reamer can be fixed on tool apron by the rose reamer of diameter, when replacement by fixing piece.

Preferably, the fixing piece includes the fixing bolt being arranged on tool apron, and described fixing bolt one end, which is located at, to be fixed Kong Zhong, and the fixing bolt is threadedly engaged with tool apron, one end that the fixing bolt is located in fixation hole is connected with arc and supports Contact, the arc contradicts piece and fixing bolt is rotatablely connected.

Through the above technical solutions, contact area is big when arc conflict piece is contacted with drill body, so that drill body and arc The frictional force contradicted between piece is larger, does not slide it is easier that generating between drill body and arc conflict piece when rose reamer is in cutting, Facilitate chamfering.

Preferably, the drill body is located on one section of outer wall in fixation hole and arc is contradicted and is all provided on piece and drill body contact surface It is equipped with anti-skid chequer.

Through the above technical solutions, anti-skid chequer further increases the frictional force between drill body and arc conflict piece, so that Rose reamer is not susceptible to loosen at work.

Preferably, be provided with the accommodating chamber that piece is contradicted for accommodating arc on the fixation hole, the arc contradict piece with When drill body contradicts, the central axis of the drill body and the rotation axis coincident of tool apron.

Through the above technical solutions, the case where being eccentrically rotated in order to avoid rose reamer, is provided with appearance in fixation hole Receive chamber, arc can be contradicted piece and accommodated by accommodating chamber, while while making in rose reamer insertion fixation hole will not contradict piece by arc Stop, be convenient for changing rose reamer, when arc contradicts piece, and rose reamer abutting is fixed in fixation hole, so that the central axis of drill body Line just with the rotation axis coincident of tool apron, when rose reamer being avoided to be eccentrically rotated can not normal chamfering the case where generation.

Preferably, the end that the fixing bolt is located in fixation hole is provided with spherical convex block, and the arc contradicts piece On be provided with convex block cooperation swivelling chute.

Through the above technical solutions, in order to avoid when fixing bolt rotates arc contradict piece and rotate, in fixed spiral shell Bolt end is provided with spherical protrusion, while contradicting on piece in arc and being provided with swivelling chute, and rotary fixing screw revolves at this time, and protrusion will It is rotated in swivelling chute, and arc contradicts piece and will not rotate in accommodating chamber, arc contradicts piece when arc being avoided to contradict piece rotation The case where can not being bonded with drill body surface.

Preferably, it is hard alloy material that the arc, which contradicts piece,.

Through the above technical solutions, hard alloy has hardness is high, wear-resisting, intensity and toughness are preferable, heat-resisting, corrosion-resistant etc. A series of excellent performances, especially its high rigidity and wearability, when in use not it is easier that arc contradicts the protection on piece surface Line is worn, so that arc contradicts piece and can have biggish frictional force between drill body always.

In conclusion the utility model having the beneficial effect that in contrast to the prior art

(1) due to not needing to be bonded with cambered surface when using, the hole in cambered surface can be processed, equally various Hole on shape face can be processed；

(2) replacement rose reamer can be convenient by fixing piece, to process the hole of different-diameter.
