Abstract
The utility model provides an assembly type non-relief-grinding small-modulus spiral bevel gear milling cutter, which comprises a cutter body. Cutter tooth grooves are distributed on the cutter body. Replaceable teeth are equipped inside the cutter tooth grooves. The bottom of each tooth is provided with a tooth fastening screw. A cutter body outer ring which is equipped outside the cutter body is provided with a fastening screw capable of adjusting the teeth. The cutter body in the utility model can be repeatedly applied. The teeth can be replaced. Meanwhile, the assembly type non-relief-grinding small-modulus spiral bevel gear milling cutter has the advantages of flexible application, adjusting convenience and long service lifetime.
Description
Technical field
The utility model relates to spiral bevel gear manufacturing and process tool field thereof.
Background technology
It is non-circular arc that domestic and international spiral bevel gear has tooth trace, is the tapered tooth and the Equal-Height Spiral Bevel Gear of circular arc as epicycloid equal-depth teeth bevel gear, tooth trace, claims spiral bevel gear.Its gear teeth of spiral bevel gear are positioned on the cone, the thick difference of its big or small end tooth, because it adopts face gear or bevel gear with 90 process principle, requiring cutter tooth cutting side edge must be linearity.The application of cutter number system and wrong cutter amount simultaneously.Above-mentioned characteristic has constituted the characteristics and the complexity thereof of current domestic and international spiral bevel gear milling cutter processing structure.
The plate-like facing cutter of current domestic and international processing small mode number spiral bevel gear is monoblock type, and the cutter tooth on the facing cutter is processed through relief grinding.And this monoblock type facing cutter is because the relief grinding machining period is big, and service wear is also big, in case the cutter tooth mill is most or a cutter tooth fracture, remaining disk body can only abandon, if cutter tooth coating is also had to whole plating.
Summary of the invention
Technical problem to be solved in the utility model provides the assembled non-relief grinding small modulus spiral bevel gear cutter that a kind of modular cutter hub can use repeatedly.For this reason, the utility model by the following technical solutions: it comprises cutter hub, is distributed with the cutter tooth groove on the described cutter hub, be provided with interchangeable cutter tooth in the cutter tooth groove, the cutter tooth bottom is provided with the cutter tooth holding screw, and described cutter hub is provided with the cutter hub outer ring outward, and the cutter hub outer ring is provided with the trip bolt that can regulate cutter tooth.
By above technical scheme, cutter hub of the present utility model can use repeatedly, and cutter tooth can be replaced, applying flexible, and levelling is convenient, and service time is long.
The utility model can also adopt following further technical scheme: cutter tooth of the present utility model is a strip, and each plane of cutter head is through mill processing, accuracy height.Cutter tooth also can grind coign on request.The cutter tooth material can be selected high-speed steel for use, high-speed steel coating or carbide alloy etc.
By above technical scheme, the utility model can carry out coating to cutter tooth separately, and selects different cutter tooth materials to reach as required cutter tooth is processed, and uses more flexible.
Description of drawings
Fig. 1 is the structural representation of embodiment that the utility model provides.
The specific embodiment
With reference to accompanying drawing, the utility model comprises plate-like cutter hub 1, and cutter hub 1 bottom can be provided with supporting disk, also can not establish supporting disk.
In the present embodiment, cutter hub 1 bottom is provided with supporting disk 3, be distributed with the cutter tooth groove on the cutter hub 1, be provided with interchangeable cutter tooth 4 in this cutter tooth groove, be provided with cutter hub outer ring 2 outside the cutter hub 1, cutter hub outer ring 2 is provided with the trip bolt 2a that can regulate cutter tooth, and holding screw 3b is located at the cutter tooth bottom, be used to regulate cutter tooth height and cutting edge concentricity, can also support the cutter tooth axially loaded.
Plate-like cutter hub 1 of the present utility model is furnished with plurality of specifications according to the diameter difference, and the corresponding cutter tooth groove of being furnished with varying number, outside blade or whole double-sided blade cutter tooth that the wide teeth groove of special processing is installed in installing at interval.Cutter hub 1 central authorities upper end is provided with trip bolt hole 1a, and this screw hole 1a is used for installing trip bolt, is screwed on the machine tool chief axis.
Plate-like cutter hub 1 bottom center is provided with the location taper hole 1b that matches with the machining tool main shaft, and cutter hub 1 below also is provided with the keyway 1c that matches with the machine tool chief axis driving key, and fastening cutter hub and outer ring screw 3a.Supporting disk 3 and screw 3a are used for fastening cutter hub 1 and outer ring, and holding screw 3b is in order to regulate cutter tooth height and concentricity.
Cutter hub of the present utility model 1 minute is cylindric and cone-shaped: when cutter hub 1 was cylinder, the cutter tooth groove was a straight trough, and groove bottom parallels to the axis; When cutter hub 1 was cone, the cutter tooth groove was a skewed slot, and groove bottom and axis tilt to have angle.
This assembly type milling cutter of the present utility model and non-relief grinding cutter tooth, applying flexible can carry out multiple combination, has simplified the tool management of spiral bevel gear specialty manufacturing works and has reduced the cutter expense.
The spiral bevel gear process tool of equal modulus during the utility model is equally applicable to.
