Abstract
The utility model provides a replaceable rotor groove milling tool. The structure of the replaceable rotor groove milling tool is composed of a tool shank made from high-strength alloy steel and a replaceable tool bit, and the assembly and connection of the flat and outer taper of the tail of the tool bit and the waist-shaped notch and tapered hole of the head of the tool shank is fixed by bolts. The replaceable rotor groove milling tool has the advantage that in the process of actual use, multiple groups of milling tools are provided to a user for the first time in order to ensure the use of a machine tool, while later orderings only need to purchase milling heads. Consequently, a tool factory also only needs a couple of same tool shanks for the production of tool bits. As a result, not only the delivery period of tools is shortened, but also materials are saved.
Description
Technical field
The utility model relates to a kind of improvement of dedicated tool, and particularly a kind of interchangeable rotor groove milling cutter is applicable to the processing and forming of the rotor groove molded lines of turbomachinery.
Background technology
The fir-tree type molded lines connects and to have the precision height, and high reliability features is so that it is used on large-size steam turbine is very extensive.That processes this molded lines mainly will use the pre-milling cutter of molded lines (tapering milling cutter), bottom land slotting cutter, bottom land molded lines milling cutter, molded lines roughing milling cutter and molded lines finish-milling cutter.Because the cost of rotor is very expensive, so very high to the reliability requirement of cutter.For guaranteeing the quality of cutter, traditional milling cutter is whole high-speed steel milling cutter.Because whole international high-speed steel price goes up continuously at present, has improved the cost of charp tool.In order to tackle this situation, some external cutter manufacturers bring into use welding structure, but because this reliability requirement to solder technology is very high, need special detection means to guarantee the quality of cutter simultaneously.So China cutter producer also dare not use this structure and continue to adopt original overall structure at present, so, cause the whole cost of charp tool high.
No matter be the employing butt welding, also be to use overall structure, during fabrication, inevitably need to consume more materials, the energy savings of advocating for country runs in the opposite direction, and is unfavorable for that also enterprise increases the benefit.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, thereby designs a kind of interchangeable rotor groove milling cutter that can overcome its deficiency effectively.
The purpose of this utility model is such realization: such milling cutter is structurally improved, change original overall structure into interchangeable structure, guarantee that simultaneously this structure has good intensity and precision.Promptly adopt the handle of a knife and the removable cutter head of high strength alloy steel, the flat and outer cone of milling head afterbody is connected with the waist type groove of handle of a knife head and taper hole assembling, is screwed.
The taper hole of described handle of a knife head is 1: 10 taper hole, and the axiality of taper hole and shank is less than 0.008mm, and conical surface contact-making surface is greater than 90%.
The flat gap of described waist type groove and cutter head is 0.02mm.
Useful good effect of the present utility model is: in actual use, provide several milling cutters in groups to guarantee the use of lathe to applying unit for the first time, order later on then only needs to buy milling head and gets final product.Like this, the cutting tool factory also only needs several identical handle of a knifes to be used for the production of cutter head.Like this, not only accelerate the delivery date of cutter, saved raw material simultaneously.
Description of drawings
Fig. 1 is a kind of (bottom land slotting cutter) of the present utility model cutter structure figure.
Fig. 2 is the side view of Fig. 1.
Code name implication among the figure: 1 cutter head, 2 screws, 3 handle of a knifes
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model adopts handle of a knife 3 and the removable cutter head 1 with high strength alloy steel, and the flat and outer cone of milling head 1 afterbody is connected with the waist type groove and the taper hole assembling of handle of a knife 3 heads, and is fixing with screw 2.The taper hole of handle of a knife 3 heads is 1: 10 taper hole, and the axiality of taper hole and shank is less than 0.008mm, and conical surface contact-making surface is greater than 90%, and taper hole is mainly used in and guarantees that milling head 1 and handle of a knife 3 have higher axiality.The flat gap of waist type groove and milling head 1 afterbody is 0.02mm, is mainly used in the transmission moment of torsion.During manufacturing, use a cover taper plug gauge and ring gauge to be used to control 1: 10 taper hole (handle of a knife) and outer cone precision (cutter head), to guarantee the continuity of precision, the shank precision is made by 6 class precisions.Because the handle of a knife of cutting tool factory and the handle of a knife of applying unit adopt same required precision to make, then the cutting tool factory according to drawing with cutter head and handle of a knife be fitted together make after, taking off on the handle of a knife that installs to applying unit also is same dimensional accuracy.So this structure is effective structure.Same structure can be generalized to the pre-milling cutter of molded lines, bottom land molded lines milling cutter, molded lines roughing milling cutter and molded lines finish-milling cutter.
Claims (3)
1. interchangeable rotor groove milling cutter is characterized in that: adopt the handle of a knife and the removable cutter head of high strength alloy steel, the flat and outer cone of cutter head afterbody assembles with the waist type groove of handle of a knife head and taper hole and is connected, and is screwed.
2. interchangeable rotor groove milling cutter as claimed in claim 1 is characterized in that: the taper hole of handle of a knife head is 1: 10 taper hole, and the axiality of taper hole and shank is less than 0.008mm, and conical surface contact-making surface is greater than 90%.
