Description

It drills and reams and unifies cutter

Technical field:

The utility model relates to oil cylinder technical field, a kind of knife for designing with the machining function of integration drilling and reamer Tool is related.

Background technique:

Existing oil cylinder manufacture field, there are many workpiece holes to need to bore, hinge processing, and the machine of existing most of aperture adds Work, all using first drilling what the process sequence to ream again carried out, it is cumbersome that there are manufacturing procedures, and processing cost is high, and production efficiency is low.

Summary of the invention:

The utility model aim is to overcome disadvantages mentioned above, provides one kind and drill and ream and unify cutter, by the machine of drill bit and reamer The dedicated tool that machining function is combined into one is realized and bores, cuts with scissors two different process for machining and can complete in the same process Machining demand.

To reach above-mentioned purpose, the utility model adopts the following technical solution:

It drills and reams and unifies cutter, by drill bit blade and the design of reamer blade same on cutter, i.e., preposition blade is drill, Postposition blade is reamer.

Further, the drill bit blade and reamer blade are arranged concentrically, and the diameter of drill bit blade is less than reamer blade Diameter, diameter difference are the cutting output of reamer.

Further, the drill bit blade is two, is symmetrical arranged along axle center, and reamer blade is two, is spaced along axle center It is symmetricly set between two drill bit blades.

By adopting the above technical scheme, the utility model, which drills and reams, unifies cutter, by drill bit blade and the design of reamer blade same On one cutter, i.e., preposition blade is drill, and postposition blade is reamer, and when cutter works, preposition drill bit blade first realizes brill Hole movement, because its blade dimensions radix smaller than the reamer blade dimensions of postposition (to processing pore size it is related), as Subsequent ream amount；And then the reamer blade of postposition realizes the movement of fraising, reamer blade dimensions are designed as processed hole The lower limit of diameter subtracts 0.02mm, and the machining in hole is completed by " the front and back cooperation " of double cutting edge." drill and ream conjunction by using this The same process that is machined into hole can be completed process requirements by one cutter ", saved tool changing movement, simplified processing technology, improve Processing efficiency.

Detailed description of the invention:

Attached drawing described herein is used to provide a further understanding of the present invention, and constitutes one of the utility model Point, the exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the utility model Improper restriction.In the accompanying drawings:

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the utility model edge plane configuration state schematic diagram；

Fig. 3 is that the utility model processes part schematic diagram.

Specific embodiment:

In order to be clearer and more clear technical problem to be solved in the utility model, technical solution and beneficial effect, with Under in conjunction with the accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein Example is applied only to explain the utility model, is not used to limit the utility model.

As shown in Figure 1-3, being the embodiments of the present invention, drills and reams and unify cutter, by drill bit blade 1 and reamer blade 2 Same on cutter, i.e., preposition blade is drill for design, and postposition blade is reamer.

Specifically, the drill bit blade 1 and reamer blade 2 is arranged concentrically, the diameter of drill bit blade is less than reamer blade Diameter, diameter difference be reamer cutting output.The drill bit blade 1 is two, is symmetrical arranged along axle center, reamer blade 2 It is two, interval is symmetricly set between two drill bit blades along axle center.

When work, when this cutter is applied in the production and processing of product, such as the hole in piece part 3 of manuscript 3, front edge adds for drilling Work, rear cutting edge followed by are ream machining so that being processed hole, whole machinings are just completed in feed again.It will bore Head blade and the design of reamer blade are same on cutter, i.e., preposition blade is drill, and postposition blade is reamer, cutter work When, preposition drill bit blade first realizes boring action, because of its blade dimensions radix smaller than the reamer blade dimensions of postposition (related to processing pore size), as subsequent ream amount；And then the reamer blade of postposition realizes the movement of fraising, hinge The lower limit that knife blade dimensions are designed as processed aperture subtracts 0.02mm, and the machine in hole is completed by " the front and back cooperation " of double cutting edge Processing.The same process that is machined into hole can be completed by process requirements by using this " drill and ream and unify cutter ", save and change Knife movement, simplifies processing technology, improves processing efficiency.

The preferred embodiment of the utility model has shown and described in above description, as previously described, it should be understood that this is practical new Type is not limited to forms disclosed herein, and should not be regarded as an exclusion of other examples, and can be used for various other groups Conjunction, modification and environment, and above-mentioned introduction or the technology of related fields can be passed through within the scope of the inventive concept described herein Or knowledge is modified.And changes and modifications made by those skilled in the art do not depart from the spirit and scope of the utility model, then It all should be in the protection scope of the appended claims for the utility model.
