Background technology
Tradition is when the counter sink of processing concentric but different pore size size, and that uses draws countersunk knife, and it is one thin and be the wolfram steel handle of a knife of eccentric state that this draws countersunk knife directly on end face, to process, and wolfram steel handle of a knife outer end also processes and is provided with cutting edge.Because traditional draw countersunk knife and wolfram steel handle of a knife, cutting edge are all formed in one, whole is drawn countersunk knife is all that wolfram steel material is made, situation once wolfram steel handle of a knife and cutting edge generation fracture or serious wear, whole is drawn countersunk knife just must abandon cannot to continue again and uses, cause virtually the waste of material that draws countersunk knife, also cause buying and draw the cost of countersunk knife and rose reamer to increase simultaneously, form a kind of added burden of processer, for it had both deposited the problem and blemish that waits to overcome solution.
What can to give up formula guide pillar countersunk knife be countersunk knife is a kind of, and it mainly consists of handle of a knife and cutter head, is fixed with two groups of symmetrically arranged blades on cutter head.Because blade is to be directly fixed on cutter head, can only process the counterbore of specific dimensions, for the counterbore of other sizes, can not process, also need blade to reinstall location troublesome poeration.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of reasonable in design, given up formula guide pillar countersunk knife that the range of work is wide.
The purpose of this utility model can realize by following technical proposal:
Ben Kesheshi guide pillar countersunk knife, comprise knife bar and the cutter head of being located at knife bar front end, on described cutter head, there are two symmetrically arranged installation portions, in described installation portion, be provided with two blades: blade one and blade two, the cutting edge of described blade one is greater than the cutting edge of described blade two to the distance of cutter head central shaft to the distance of cutter head central shaft, it is characterized in that, in described installation portion, be provided with the mount pad that can move radially along cutter head, on described mount pad, there are two mounting grooves: mounting groove one and mounting groove two, above-mentioned blade one is positioned at described mounting groove one, above-mentioned blade two is positioned at described mounting groove two, between described mount pad and cutter head, have and after cutter head moves into place, can make mount pad be fixed on the fixed structure on cutter head.
With this countersunk knife, add man-hour, blade one is fixed in mounting groove one, blade two is fixed in mounting groove two, then, under the effect of fixed structure, mount pad is fixed in the installation portion on cutter head, workpiece is processed.When changing processed aperture, make, unclamp fixed structure, regulate the position of mount pad, after adjusting, by fixed structure, mount pad is being fixed, have easy to adjust, the advantage such as the range of work is wide.
In above-mentioned given up formula guide pillar countersunk knife, described fixed structure comprises the radial direction through hole being positioned on cutter head and is located at the lead on mount pad, described lead is located in this radial direction through hole, on described cutter head, be also provided with its inner and be inserted into the bolt in radial direction through hole, the perpendicular setting of described bolt and lead.
In above-mentioned given up formula guide pillar countersunk knife, on described installation portion, there is the stopper slot matching with above-mentioned mount pad, described mount pad is positioned at this stopper slot.
In above-mentioned given up formula guide pillar countersunk knife, the cross section of described radial direction through hole is ellipticity, and the cross section of described lead is ellipticity.Elliptoid radial direction through hole and elliptoid lead support the use, and can prevent that lead from circumferentially rotating, and when bolt abuts on lead, it is inner large with the contact area of lead, and structural stability is high.
Compared with prior art, originally can give up formula guide pillar countersunk knife has the following advantages:
By increasing mount pad, realize the change of distance between blade and cutter head central shaft, by the radial direction through hole and the lead that arrange, conveniently mount pad position is regulated, be easy to change after breaks down, stability is high, machining accuracy is high, and the range of work is wide, long service life.
