Description
Technical field
The utility model is related to machining tool technical field, particularly a kind of ream for being used to remove bolt hole counterbore burr
It bores.
Background technology
At present, in the processing of wheel hub industry, there are many bolt hole counterbore deburring operation of wheel shape, though problem is small, solution
It determines and really causes considerable trouble, common processing method one is：Traditional habit goes to file with file, and this way can also reach substantially to be added
The requirement of work, but it is poor and time-consuming and laborious to process uniformity.Second is that：With the machinery of deburring, by passing through various flowings in hole
Liquid solid by the way that so as to achieve the effect that take away burr, this method is not thorough many times, it is also necessary to special machine
Tool.Third,：One manual burring knife is made by oneself according to the shape in hole, use is more convenient, but shortcoming is because manually strength has
Limit, can only remove aluminum component, and the burr removal of copper piece, plastic part can not use high-volume, efficient production and processing to need, especially
It is the difficulty to bolt hole counterbore deburring.
The content of the invention
The purpose of this utility model is the deficiency of prior art problem to be solved, and provides one kind for removing bolt hole counterbore
The counterbit of burr disposably completes the processing of bolt hole counterbore deburring using the automatic tool changer function of machining center, meets former
Same weekly, the verticality technology requirement in beginning hole.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme：
A kind of counterbit for being used to remove bolt hole counterbore burr, including knife bar, knife bar includes shank section and connects with shank section
The knife bar portion connect；The end in the knife bar portion is fixed with to be set with the matched cylinder of counterbore internal diameter, the bottom outer-edge of the cylinder
Have chamfering, be evenly equipped with several deburring cutting edges in the chamfering, the outer ledge of the deburring cutting edge and cylinder it is outer
Periphery is tangent, and the deburring cutting edge top extends to column top and axially offers ash pit in cylinder side wall,
The lower face of the cylinder is fixed with to be overlapped with the matched lead of bolt hole, the lead with the axial line of knife bar.
Further, the deburring cutting edge is arranged to 3.
Preferably, the diameter of the shank section is more than the diameter in knife bar portion.
Compared with prior art, the utility model can be after bottom outlet machines without interrupting or replacing process
Bolt hole counterbore burr is removed, substantially increases processing efficiency, the utility model is simple in structure, beneficial to popularization.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is enlarged drawing at the A of Fig. 1.
Fig. 3 is the usage state diagram of the utility model.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings and specific embodiments, in the signal of this utility model
Property embodiment and explanation be used for explaining the utility model, but be not intended to limit the scope of the present invention.
A kind of counterbit for being used to remove bolt hole counterbore burr as shown in Figure 1 and Figure 2, including knife bar, knife bar includes handle of a knife
Portion 1 and the knife bar portion 2 being connected with shank section 1, the diameter of shank section 1 are more than the diameter in knife bar portion 2；The end in the knife bar portion 2
Cylinder 3 matched with counterbore internal diameter is fixed with, the bottom outer-edge of the cylinder 3 is equipped with chamfering, 3 are evenly equipped in the chamfering
Deburring cutting edge 5, the outer circumference surface of the outer ledge and cylinder 3 of the deburring cutting edge 5 is tangent, the deburring cutting
5 top of sword extends to 3 top of cylinder and axially offers ash pit 6 in 3 side wall of cylinder, and the lower face of the cylinder 3 is fixed
There is lead 4 matched with bolt hole, the lead 4 is overlapped with the axial line of knife bar.
Ability utility model utilizes in use, as shown in figure 3, after counterbore using the complete bolt hole of Cutter Body Processing with Machining Center
The shank section 1 of the counterbit for removing bolt hole counterbore burr of the utility model is mounted in processing by automatic tool changer function
The heart, then, you can the disposable processing for completing bolt hole counterbore deburring, deburring cutting edge 5 realize the interior hair to counterbore
Row cutting polishing is lunged, lead 4 can make whole device meet the same weekly of original bolt hole and counterbore, and verticality technology will
It asks, meanwhile, cylinder 3 can also play position-limiting action, prevent the intensification to counterbore and bore hole during deburring.
The technical solution of the utility model is not limited to the limitation of above-mentioned specific embodiment, every skill according to the present utility model
The technology deformation that art scheme is made, each falls within the scope of protection of the utility model.
