Description
Technical field
The utility model relates to a kind of biserial worm milling cutter, belongs to the milling cutter technical field.
Background technology
Worm screw is extensive application in machine driving.The number of teeth of worm screw is many more, and lead angle is big more, and transmission efficiency is just high more, so in requiring the high worm gear transmission of transmission efficiency, often adopt multistart worm.But number of threads is many more, lead angle is big more, and processing is just difficult more.Because worm screw is processed on lathe usually, the worm screw helical pitch increases to turning processing brings many disadvantages of the big feed of low speed, as: working (machining) efficiency is low, blade easily collapses; Owing to typically use a lathe tool and cut, the cutter tooth that participates in cutting is few again, so there is defective such as blade quick abrasion; In addition, cause separately often,, worm accuracy is reduced so easily produce the error of division because working (machining) efficiency is low.
The utility model content
The purpose of this utility model is: a kind of biserial worm milling cutter is provided, can reduces worm screw processing number of times, raising working (machining) efficiency and machining accuracy height separately.
The technical solution of the utility model:
A kind of biserial worm milling cutter, it comprises cutter hub 1, and cutter hub 1 is provided with locating hole 2, and the cylindrical 3 of cutter hub 1 is provided with two row cutters tooth 4.
Aforesaid biserial worm milling cutter, two row cutters tooth 4 are symmetricly set on the cylindrical 3; The lip surface 5 of cutter tooth 4 is parallel with the axis direction of locating hole 2.
Use the utility model processing multistart worm, one-pass can process a complete worm tooth and two teeth groove, makes shorten 2～3 times the process time of multistart worm, can reduce number of times, raising working (machining) efficiency and machining accuracy height separately.The utility model manufacturing is simple, sharpening convenience, compact conformation, be difficult for tipping.The utility model can be installed and used on milling machine, screw-thread miller and lathe easily.The utility model has reduced the difficulty of multistart worm processing, can make multistart worm realize producing in enormous quantities.
Description of drawings
Accompanying drawing 1 is a front view of the present utility model;
Accompanying drawing 2 is the left view of accompanying drawing 1;
Accompanying drawing 3 is cutter tooth 4 structural representations of the present utility model;
Accompanying drawing 4 is a scheme of installation of the present utility model.
The specific embodiment
Embodiment of the present utility model:
The initial parameter of known processed worm screw is: the last tooth depth h ' of worm screw modulus m, number of threads Z, worm screw axial module M, normal profile angle α n, worm screw, the following tooth depth h of worm screw ", the lead angle β of worm screw.
The utility model biserial worm milling cutter designs and produces
The tooth profile parameter of cutter tooth 4 calculates, as accompanying drawing 3:
Tooth pitch tn=π M/COS β
Transverse tooth thickness Sn=tn/2-Δ S Δ S is that the transverse tooth thickness of worm screw is stayed the mill surplus
Last tooth depth h1=h "
Fully teeth height h=h '+h "+0.1～0.2M
Profile angle α=α n
The physical dimension of biserial worm milling cutter is calculated, is selected, as accompanying drawing 1, accompanying drawing 2, accompanying drawing 2:
The outer diameter D of biserial worm milling cutter is chosen between 80～120mm, and the maximum outside diameter that is no more than erection unit energy mounting cutter gets final product;
The diameter d of locating hole 2 is pressed the standard aperture of disc milling cutter and is selected between φ 22, φ 27, φ 32, φ 40, should select greatlyyer as far as possible, can improve processing stability; Size (d+t1) and b choose by the keyway size selection principle in the Course Exercise in Machinery Elements Design.
Cutter hub width B=tn+Sn+2 (h-h1) tg α+2～3mm.
Other parameters of biserial worm milling cutter are selected
Parameters such as the flute degree of depth of biserial worm milling cutter, anterior angle, top relief angle, side edge relief angle and the cutter number of teeth, method for designing is all consistent with the dish type angle milling cutter; The profile accuracy of biserial worm milling cutter is than the high 1-2 of the precision grade of processed worm screw.
Make the biserial worm milling cutter according to above-mentioned parameter, on the cylindrical 3 of cutter hub 1, process two row cutters tooth 4; Two row cutters tooth, 4 symmetries are produced on the cylindrical 3, make the lip surface 5 of cutter tooth 4 parallel with the axis direction of locating hole 2.
The installation adjusting method of the utility model biserial worm milling cutter is an example with installation on J620 type screw-thread miller and using method, as Fig. 4;
Earlier biserial worm milling cutter 6 is installed on the knife bar 7 by locating hole 2, compresses with packing ring, nut; Unclamp four bolts 9 on the swivelling tool-holder 8, rotate swivelling tool-holder 8, direction of rotation is decided according to the rotation direction of institute's machining worm, worm screw turns clockwise during for dextrorotation, worm screw is rotated counterclockwise when being left-handed, the angle ω of rotation equals the lead angle β of worm screw, rotates to four bolts 9 of locking after the required angle; Unclamp the bolt 11 on the follow rest 10, put down tool setting rule 12, move axially knife bar 7, the circle that makes tool setting rule 12 is in the middle of two row cutters tooth 4 of biserial worm milling cutter 6 to cutter head, and clamping screw 11 is packed up tool setting rule 12 and got final product.
The using method of the utility model worm screw biserial worm milling cutter:
Select cutter rotating speed, feeding speed to get final product by the cutting data of common disc milling cutter; Change gear a/b * c/d is found in decimal ratio i=10 π mZ/3 * 127 in general ratio change gear table, load onto change gear; Number Z by processed worm screw selects to install index plate; Milling depth " is processed by fully teeth height H=h '+h of worm screw.Number of times calculates according to processed number of threads Z separately, and when Z was even number, number of times was Z/2 separately; When Z was odd number, number of times was (Z+1)/2 separately.When calibration, the direction of rotation of index dial should remain unanimity, to avoid because of lathe and to hang the opinion gap worm accuracy is reduced, since the calibration first time, by the selected calibration teeth groove of the parted hair number of times that calculates, calibration processing one by one successively is until whole worm tooth completion of processing.
