Abstract
A kind of multiplex pcb board profile milling cutter, blade is connected with shank one end, and the shank other end is chamfering, the blade of milling cutter is simultaneously provided with left-hand thread and right-hand thread, the edge of a knife kernel of section of blade is provided with screwed hole, and saw-tooth milling cutter is provided with threaded post, and screwed hole is threaded connection with threaded post.Left-hand thread and right-hand thread at least extend on the neck of milling cutter.Saw-tooth milling cutter can also be the milling cutter of the other structures such as plain cutter, side mill, face milling cutters.By adopting said structure, brill miller is carried out using the screw thread of two different directions simultaneously and make, a threaded bore milling, a screw thread chip removal, very convenient；And extend to a screw thread at knife neck, enable stress point during boring milling for the milling cutter to be distributed to shank, increase fracture resistence force intensity in chip-breaker, lift the milling cutter life-span；It is threaded hole in milling cutter termination, the milling cutter of other structures can be threaded connection and be fixed on its termination, the replacing of convenient difference milling cutter, and the small volume of the milling cutter changed, it is convenient for carrying.
Description
Technical field
The present invention relates to milling field is bored in pcb board molding, particularly a kind of multiplex pcb board profile milling cutter is put.
Background technology
Existing milling cutter construction is single, during carrying out pcb board brill milling shaping work, needs ceaselessly milling cutter to be changed, and to meet the different demands boring milling, frequently replacing milling cutter is not only very time-consuming, and milling cutter species is many, carries also inconvenience.
Content of the invention
The technical problem to be solved is to provide a kind of multiplex pcb board profile milling cutter, realizes the replacing between various structures, make brill milling process convenient on same milling cutter.
For solving above-mentioned technical problem, the technical solution adopted in the present invention is：A kind of multiplex pcb board profile milling cutter, blade is connected with shank one end, and the shank other end is chamfering, the blade of milling cutter is simultaneously provided with left-hand thread and right-hand thread, the edge of a knife kernel of section of blade is provided with screwed hole, and saw-tooth milling cutter is provided with threaded post, and screwed hole is threaded connection with threaded post.
Preferably in scheme, described left-hand thread and right-hand thread at least extend on the neck of milling cutter.
Preferably in scheme, described saw-tooth milling cutter can also be flat-end cutter, rose cutter, profile milling cutter, rose reamer, T-shaped knife, flute profile knife and rough bark knife.
A kind of multiplex pcb board profile milling cutter that the present invention provides, by adopting said structure, carries out brill miller using the screw thread of two different directions simultaneously and makees, a threaded bore milling, and a screw thread chip removal is very convenient；And extend to a screw thread at knife neck, enable stress point during boring milling for the milling cutter to be distributed to shank, increase fracture resistence force intensity in chip-breaker, lift the milling cutter life-span；It is threaded hole in milling cutter termination, the milling cutter of other structures can be threaded connection and be fixed on its termination, the replacing of convenient difference milling cutter, and the small volume of the milling cutter changed, it is convenient for carrying.
Brief description
The invention will be further described with reference to the accompanying drawings and examples：
Fig. 1 is the overall structure diagram of the present invention.
In figure：Blade 1, shank 2, chamfering 3, left-hand thread 4, right-hand thread 5, neck 6, the edge of a knife 7, screwed hole 8, saw-tooth milling cutter 9, threaded post 10.
Specific embodiment
As in figure, a kind of multiplex pcb board profile milling cutter, blade 1 is connected with shank 2 one end, shank 2 other end is chamfering 3, the blade 1 of milling cutter is simultaneously provided with left-hand thread 4 and right-hand thread 5, the edge of a knife 7 kernel of section of blade 1 is provided with screwed hole 8, and saw-tooth milling cutter 9 is provided with threaded post 10, and screwed hole 8 is threaded connection with threaded post 10.
Preferably in scheme, described left-hand thread 4 and right-hand thread 5 at least extend on the neck 6 of milling cutter.
Preferably in scheme, described saw-tooth milling cutter 9 can also be flat-end cutter, rose cutter, profile milling cutter, rose reamer, T-shaped knife, flute profile knife and rough bark knife.
By adopting said structure, brill miller is carried out using the screw thread of two different directions simultaneously and make, a threaded bore milling, a screw thread chip removal, very convenient；And extend to a screw thread at knife neck, enable stress point during boring milling for the milling cutter to be distributed to shank, increase fracture resistence force intensity in chip-breaker, lift the milling cutter life-span；It is threaded hole in milling cutter termination, the milling cutter of other structures can be threaded connection and be fixed on its termination, the replacing of convenient difference milling cutter, and the small volume of the milling cutter changed, it is convenient for carrying.
