Abstract

The utility model is related to field of machining, disclose a kind of cutting reamer cutter being processed and formed at one time for more sizes, include cutter head, knife neck, handle of a knife, pass through the Optimal Structure Designing to helical flute and cutting edge, the product size of cutting reamer tool sharpening is stable and geometric tolerance is effectively controlled, the connection structure synchronous processing between each shape, it is processed simultaneously instead of plurality of specifications cutter, greatly improves the production efficiency of product, reduce manufacturing cost；The product that cutting reamer Tool Design by rational design may extend into company is related to the technical aspect that more sizes are needed while being processed.

Description

A kind of cutting reamer cutter being processed and formed at one time for more sizes

Technical field

The utility model is related to field of machining, especially a kind of cutting reamer being processed and formed at one time for more sizes Cutter.

Background technology

Aviation hydraulic system valve body product structure is complicated, and size requires and Geometrical Tolerance Principle is all very high, concentricity with it is same It is that different sizes use different size tool sharpening that higher, the prior art are required in terms of heart degree.Accumulation is generated in process to miss Difference is larger, and size requires and geometric tolerance is difficult to ensure, and process time and process-cycle are long, and high processing costs, efficiency is low, Unstable product quality.

The tool precision requirement of all specifications of the existing technology to using is all very high, and number of cutters is more, the cost of charp tool Height, debugging cycle is long, and generation accumulated error is larger in process, and size requires and geometric tolerance is difficult to ensure, and adds Long with the process-cycle between working hour, high processing costs, efficiency is low, unstable product quality, and product fraction defective is high.

Invention content

The cutting reamer cutter that the purpose of this utility model is to provide a kind of to be processed and formed at one time for more sizes, for On product on same axis around the size being related in terms of different-diameter, shape and identical concentricity carry out it is disposable Processing, the dimensionally stable of all diametricallies, concentricity consistency are good.The tool category of a variety of different sizes is merged into one kind Cutter, i.e. cutter kind are reduced, and eliminate the accumulated error in process, size requires and geometric tolerance is effectively controlled System, process time shorten with the process-cycle, reduce processing cost, and efficiency is improved, and product quality is stablized, and reduce product not Yield effectively controls operation cost.

To realize above-mentioned technical purpose and the technique effect, the utility model discloses one kind being used for more sizes one The cutting reamer cutter of secondary property machine-shaping, includes cutter head, knife neck, handle of a knife, and cutter head is connected with knife neck, and knife neck is connected with handle of a knife, Two groups of helical flutes are offered on cutter head, two groups of helical flutes are in rotational symmetry structure, and cutter head entity part is arranged with spiral It considers to be worth doing and forms cutting edge at the intersection of slot, cutting edge is equipped with rake face and flank, and the rake face of cutting edge contacts tool with workpiece There are anterior angle, the flank of cutting edge to contact relief angle, respectively the first relief angle and the second relief angle there are two tools with workpiece.

Wherein, chip pocket, 5 ° of the outer taper of helical flute are equipped in helical flute.

Wherein, the anterior angle that the rake face of cutting edge is contacted with workpiece is 8~15 °.

Wherein, the first relief angle and the second relief angle that the flank of cutting edge is contacted with workpiece are respectively 10~15 ° and 28 ~40 °.

Wherein, the second relief angle that the flank of cutting edge is contacted with workpiece has third face.

The utility model has the advantages that：

1. the utility model is by Optimal Structure Designing, the product size of cutting reamer tool sharpening stablizes and geometric tolerance obtains Connection structure synchronous processing between effective control, each shape, processes instead of plurality of specifications cutter, greatly improves product simultaneously Production efficiency, reduce manufacturing cost.

It is needed simultaneously 2. the product that may extend into company by the cutting reamer Tool Design rationally designed is related to more sizes The technical aspect of processing.

Specific implementation mode

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.

As shown in Figs. 1-3, the cutting reamer cutter that the utility model discloses a kind of to be processed and formed at one time for more sizes, Include cutter head, knife neck, handle of a knife, cutter head is connected with knife neck, and knife neck is connected with handle of a knife, and two groups of helical flutes are offered on cutter head 1, two groups of helical flutes 1 are in rotational symmetry structure, and cutting edge 2 is formed at cutter head entity part and the intersection of helical flute 1, Cutting edge 2 is equipped with rake face and flank, and the rake face of cutting edge 2 is contacted with workpiece with anterior angle 3, the rear knife of cutting edge 2 Face contacts tool with workpiece, and there are two relief angles, respectively the first relief angle 4 and the second relief angle 5.

Wherein, chip pocket 6,5 ° of the outer taper of helical flute 1, the rake face of cutting edge 2 are equipped in helical flute 1 The anterior angle 3 contacted with workpiece is 8~15 °, the first relief angle 4 and the second relief angle 5 that the flank of cutting edge 2 is contacted with workpiece Respectively 10~15 ° and 28~40 °, the second relief angle 5 that the flank of cutting edge 2 is contacted with workpiece has third face 7.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.
