Abstract
The utility model discloses a kind of machining combination bottoming reamers, it is characterized by comprising (3) three knife bar (1), cutter head (2), cutter blade parts, knife bar (1) uses T10A material, diameter, precision and machine tool chuck matching；Cutter head (2) and knife bar (1) are same entity, and size is according to the diameter limitation near upper end hole, and length is by the length limitation near upper end hole, by the profile, the flute profile that mill out mountable cutter blade；Cutter blade (3) material is YL10A, is embedded on cutter head with six cutter blades.The utility model is available to fast implement the mass production with stepped hole part, improves efficiency, reduces cost, solves the problems, such as stepped hole processing efficiency is low and is low with precision.
Description
Technical field
The utility model relates to technical fields of mechanical processing, and in particular to a kind of machining accuracy for improving stepped hole and
The combination bottoming reamer of processing efficiency.
Background technique
In mechanical processing industry, electromechanical liquid product constantly incorporates modern mechanical, and to mechanical structure, more stringent requirements are proposed.
Stepped hole is structure common in electromechanical liquid product, but for a change, the precisions such as solenoid valve to be installed in stepped hole
Hydropneumatic component, it is desirable that have higher cooperation precision.So the precision in respective steps hole will be with the precision of mating parts
Matching, difficulty of processing is big, and required precision is high, and processing efficiency is low, at high cost.Modern production does not require nothing more than processing efficiency, more infuses
Weight processing quality.Stepped hole each section of concentricity, dimensional accuracy, form accuracy, rough surface etc. are always the problem processed.For solution
Certainly such a problem, this patent, which devises one, can be improved processing efficiency, it is ensured that the combination of higher machining accuracy
Bottoming reamer.
Currently, in the processing technique field of stepped hole, the multiple tool changing and feeding for relying on numerically-controlled machine tool cause come what is completed
In process, a certain cutter occur wearing or process system in other factors variation unqualified, the knife that will affect bulk of components
Tool is scrapped, part rejection, causes the great wasting of resources.
Summary of the invention
The purpose of this utility model is to provide a kind of technical requirements design combination bottoming reamers according to hole, by cutter
Design, can be improved efficiency with the mass production with stepped hole part is fast implemented, reduce cost, be solved stepped hole and added
Work low efficiency and the low problem of precision.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of machining combination bottoming reamer, including 3 three knife bar 1, cutter head 2, cutter blade parts, knife bar 1 use
T10A material, diameter, precision and machine tool chuck matching；Cutter head 2 and knife bar 1 are same entity, and size is according near upper end
The diameter in hole limits, and length is by the length limitation near upper end hole, by the profile, the flute profile that mill out mountable cutter blade；Knife
3 material of sheet body is YL10A, is embedded on cutter head with six cutter blades.
A kind of machining combination bottoming reamer, carries out heat treatment and reaches HRC55 ~ 60, guarantee after machining
Enough hardness and strength；Heat treatment by size carries out grinding finishing after meeting the requirements, and reaches required precision, the precision,
Refer to tool dimension, shape and position precision, according to depending on workpiece accuracy, an accuracy class at least higher than workpiece accuracy.
A kind of machining combination bottoming reamer designs if requiring concentricity in the case that stepped hole is more
Combination bottoming reamer increase step number.
Before using this cutter, workpiece needs to carry out preprocessing, and guarantee leaves small surplus.
By adopting the above-described technical solution, the beneficial effects of the utility model are:
Machining accuracy not only can be improved in machining high-precision stepped hole in the utility model, can also improve processing effect
Rate, it is ensured that each hole concentricity is consistent, meets requirement of the part to assembly.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the left view of Fig. 1.
In figure: 1, knife bar；2, cutter head；3, cutter blade.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments, based on the implementation in the utility model
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig. 1-2, a kind of machining combination bottoming reamer, including 3 three knife bar 1, cutter head 2, cutter blade parts, knife
Bar 1 uses T10A material, diameter, precision and machine tool chuck matching；Cutter head 2 and knife bar 1 are same entity, and size is according to most
Diameter by upper end hole limits, length by the length limitation near upper end hole, through milling out mountable cutter blade 3 profile,
Flute profile；3 material of cutter blade is YL10A, is embedded on cutter head with six cutter blades.
A kind of machining combination bottoming reamer, carries out heat treatment and reaches HRC55 ~ 60, guarantee after machining
Enough hardness and strength；Heat treatment by size carries out grinding finishing after meeting the requirements, and reaches required precision, the precision,
Refer to tool dimension, shape and position precision, according to depending on workpiece accuracy, an accuracy class at least higher than workpiece accuracy.
A kind of machining combination bottoming reamer designs if requiring concentricity in the case that stepped hole is more
Combination bottoming reamer increase step number.
Machining accuracy not only can be improved in machining high-precision stepped hole in the utility model, can also improve processing effect
Rate, it is ensured that each hole concentricity is consistent, meets requirement of the part to assembly.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art can readily occur in variation in the technical scope that the utility model discloses
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be wanted with right
Subject to the protection scope asked.
