Abstract
The utility model relates to a hard alloy trepanning drill with a guide strip, which is mainly applicable for the hole processing in the machinery processing industry. The drill belongs to the hardware processing tool. The drill comprises at least two blades and at least two scrap discharging grooves. Each blade and each scrap discharging groove are arranged at intervals. Wherein the outside surface of the blade likes a circular arc; an anti-shaking guide strip is fixed in the circumference direction of the outside surface of each blade; and the anti-shaking guide strip is matched with the outside surface of the blade. The drill is structured rationally. An excircle locating guide strip is additionally arranged on a drill bit body. The drill prevents the firm cutter phenomenon of the inner hole of the lateral excircle resulted from the shaking of the blade, improves the use efficiency and the service life of the drill bit and improves the processing precision.
Description
Technical field
The utility model relates to a kind of cylindrical drill, particularly a kind of carbide alloy cylindrical drill of tape guide bar, and it mainly is applicable to the hole processing in the mechanical processing industry, belongs to the five metals machining tool.
Background technology
In the prior art, general carbide alloy cylindrical drill is to rely on the rigidity of machining tool itself and end tooth-shape structure guarantee that drill bit produces in working angles rock, and prevents that the side cylindrical from appearring in drill bit, the knife phenomenon appears in endoporus.This way has several shortcomings:
When the end profile of tooth tipping occurs or wearing and tearing are, the location, end relies on will be very poor;
The lathe rigidity can along with the increase of drilling depth worse and worse, the appearance of drill bit knife situation will appear;
After cutting produced and rocks, the machining accuracy in hole is variation thereupon.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned shortcoming in the prior art, and provide a kind of carbide alloy cylindrical drill of tape guide bar of reasonable in design, reduce rocking in the working angles with the drill body location, improve drill bit service efficiency and service life, improve machining accuracy.
The technical scheme in the invention for solving the above technical problem is: the carbide alloy cylindrical drill of this tape guide bar comprises at least two blades and at least two chip areas, each blade and chip area are spaced, it is characterized in that: the outer surface of described blade is circular-arc, circumferencial direction at each blade outer surface all is fixed with the anti-rock gib block, and the outer surface of this anti-rock gib block and blade is complementary.
As preferably, the outer surface of described anti-rock gib block and blade fuses.
As preferably, described anti-rock gib block is embedded on the outer surface of blade.
As preferably, the number that described anti-rock gib block is distributed on each blade outer surface equates.
The utility model compared with prior art, have the following advantages and effect: reasonable in design, increase cylindrical location sliver by drill body, prevented that blade cut from rocking and cause that the knife phenomenon appears in the endoporus of side cylindrical, improve the service efficiency and the service life of drill bit, improved machining accuracy.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation left view of Fig. 1.
Fig. 3 is the perspective view of the utility model embodiment.
The specific embodiment
Referring to Fig. 1-Fig. 3, present embodiment mainly is made up of shank 1 and blade 2.Wherein: blade 2 comprises at least two blades 21 and at least two chip areas 22, and each blade 21 and chip area 22 are spaced; Blade 2 usefulness carbide alloy are made.
The outer surface of described blade 21 is circular-arc, all is fixed with anti-rock gib block 212 at the circumferencial direction of each blade 21 outer surface, and this anti-rock gib block 212 is complementary with the outer surface of blade 21; It can be one or more that described anti-rock gib block 212 is distributed on the outer surface of each blade 21, but the number that anti-rock gib block 212 is distributed on each blade outer surface equates, a blade outer surface promptly of the present utility model is provided with one or more anti-rock gib blocks, and then correspondence is provided with one or more anti-rock gib blocks on other blade outer surface of the present utility model.In the present embodiment, be provided with two pairs of anti-rock gib blocks 212 on the outer surface of each blade 21, the cross section of each anti-rock gib block 212 is semicircle shape.
The outer surface of described anti-rock gib block 212 and blade 21 fuses or is embedded on the outer surface of blade 21.
The utility model is by increasing anti-rock gib block 212 and can effectively reduce drill bit and having processed gap between hole wall, what produced when having prevented bit cutting rocks, then cause that the knife phenomenon appears in side cylindrical, endoporus, improved the service efficiency and the service life of drill bit, improved machining accuracy.
All those of ordinary skill in the art all can implement the utility model by above description.
Specific embodiment described in this specification, the title that each part is got can be different; Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model.
