Abstract
The utility model relates to a boring cutter. The boring cutter comprises a blade and a cutter bar, wherein the cutter bar is a uniform columnar cutter bar; a cavity which is matched with the blade and is vertical to the axis of the cutter bar is arranged on the cutter bar, close to one end of the blade; at least one fastening bolt for fastening the blade vertically is arranged on the end face of the cutter bar; an adjusting bolt for adjusting and propelling the blade is arranged on the cutter bar, behind the cavity; and the adjusting bolt is adjusted by a screw to propel the blade. The boring cutter has the following technical effects: by adjusting the blade, the cutter bar of the boring cutter is unnecessary to change frequently, thus reducing the labor intensity of workers; and the uniform columnar cutter bar does not affect use of the cutter and improves the rigidity of the cutter, thus improving the production efficiency and greatly saving the production cost.
Description
Technical field
The utility model relates to a kind of borer.
Background technology
At present, the boring cutter on the market generally all has only a cutter head, this boring cutter in use, in case tool bit abrasion, whole boring cutter has just become waste product, such boring cutter has just almost become disposable product, promptly does waste disposal after the disposable use, the waste resource.And the workman in use changes boring cutter continually, causes production efficiency to reduce, and has wasted a large amount of manpower and materials.
Summary of the invention
The utility model is directed against the disposable use of cutter head in the prior art, a large amount of wastes of knife bar, and workman's frequent change boring cutter causes production cost high, and shortcomings such as production efficiency reduction can be practiced thrift the borer of cost through regulating blade thereby provide a kind of.
In order to solve the problems of the technologies described above, the utility model is able to solve through following technical proposals:
A kind of borer comprises blade and knife bar, and knife bar is even column knife bar, on knife bar, be provided with blade to cooperate and the cavity vertical with the knife bar axle center near an end, this end face have vertical fastening blade fastening bolt at least one.
As preferably, described knife bar end face has the fastening bolt of two, fastening blades vertical with blade.
As preferably, be positioned at the cavity rear side on the described knife bar, be provided with the adjustment propulsion blade and regulate bolt.
As preferably, described adjusting bolt is a hexagon socket head cap screw, regulates bolt through the screw rod adjustment, with propulsion blade.
The utility model is owing to adopted above technical scheme; Has significant technique effect:, make boring bar not need frequent change, thereby reduced working strength of workers through regulating blade; And uniform column knife bar does not influence the use of cutter; Improve the rigidity of cutter, improved production efficiency, practiced thrift production cost greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model
The structural representation that Fig. 2 is to use screw rod to regulate
Fig. 3 is the A place enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 3 and embodiment the utility model is described in further detail:
Embodiment 1
A kind of borer, as shown in Figure 1, comprise blade 1 and knife bar 2; Knife bar 2 is even column knife bar; On knife bar, be provided with blade and cooperate and the cavity 5 vertical with the knife bar axle center near an end, this end face have vertical fastening blade fastening bolt 4 at least one, through fastening bolt 4 fixed blades 1; Through adjustment fastening bolt 4, regulate fastening blade 1.
A kind of borer shown in Fig. 1-2, comprises blade 1 and knife bar 2; Knife bar 2 is even column knife bar, on knife bar, is provided with blade near an end to cooperate and the cavity 5 vertical with the knife bar axle center, and knife bar 2 end faces have the fastening bolt 4 of two, fastening blades vertical with blade; Be positioned at the cavity rear side on the knife bar 2, be provided with the adjustment propulsion blade and regulate bolt 3, regulating bolt 3 can be that external hexagonal spiral shell head also can be a hexagon socket head cap screw; And be the maximized use that do not influence in this case study on implementation; Be preferably hexagon socket head cap screw, regulate bolt 3 through screw rod 6 adjustment, with propulsion blade 1.
In a word, the above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
