Beneficial effect:
(1) the utility model is realized " the to cut the generation mill " theory to the timber finishing step, has avoided the generation of dust and has reduced noise.The bits that the sander grinding produces are chip, must follow the generation of dust, and the corn milling produces, are continuous shape volume bits or band bits, have avoided the generation of dust; The grinding of sander belongs to interrupted cut in addition, in process, impacts obviously, certainly lead to noise, and the corn milling process is mild, vibrates littlely, and the noise that produces also can reduce.So the corn milling mode can solve the hidden danger of sander environmental pollution.
(2) basis is novel can significantly reduce cutting force and improve surface quality.Tool Design becomes sped structure, and can make blade is to participate in cutting by sword, with the sander diamond particles, participates in simultaneously grinding and compares cutting on cross direction, and cutting force can obviously reduce; Originally novel on the other hand is to complete cutting under high speed, and under identical machining condition, thickness of cutting will obviously reduce, and cutting force also can reduce.Cutting force reduces, and cuts accordingly power used and also can reduce.Another advantage that cutting force reduces, reduce the difficulty of timber when shearing slip exactly, and when shearing slip was easy, the surface roughness value of workpiece will reduce, and surface quality improves.
(3) this novel butterfly spring that is equipped with below tool rest, adjusts the upper-lower position of blade by butterfly spring, make up the wearing and tearing of tool cutting process, and the while can be improved the utilization rate of cutter material.
(4) basis is novel has realized eccentric balance weight structure by design eccentrically mounted weight end cap, joint bolt and 3 parts of counterweight pull bar, can improve the integral rigidity of cutter on the one hand, can realize the adjusting of cutter high-speed balancing on the other hand, guarantee the stable operation of cutter.

The specific embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of timber highspeed spiral type maize milling cutter, and this maize milling cutter comprises blade 1, cutter 2 and counterweight end cap 3, the cutter likeness in form " corn " of arranging, and cutter adopts fabricated structure, is convenient to mounting or dismounting.
The diameter at maize milling cutter point of a knife place is designed to φ 180mm, and the blade diameter is φ 150, and cutter exposes blade 15mm, and the cutter rotary speed is 5000rpm, and corresponding cutting linear velocity is 2800m/min, is in the zone of high-speed cutting; The width design of cutter is 450mm, and is wide to the milling width adequate of common timber.
Blade 1 is along circumferentially being evenly distributed with the spiral step trough of 4 row, ladder width in spiral step trough is 50mm, on the spiral step trough of the 1st and 3 row, be evenly equipped with 9 insert grooves, the 2nd and 4 rows be evenly equipped with on spiral step trough 8 insert grooves and with the 1st and 3 row's insert grooves 25mm that staggers, avoid the gap of adjacent cutter in same-handed formula step trough on timber, to stay tool marks, the inside of blade adopts the cylindrical cavity structure to reduce the own wt of maize milling cutter, in end, with the counterweight end cap, connects.
As shown in Figure 2, on maize milling cutter, have 34 cutters, the spiral angle between adjacent cutter is 10 °, and the cylindrical cavity structure is adopted in the inside of blade, in end, with counterweight end cap 3, connects, and 3 uniform counterweight pull bars are arranged on the counterweight end cap.
As shown in accompanying drawing 3 and accompanying drawing 4, counterweight end cap 3 mainly comprises end-cover axle 4, joint bolt 5, eccentrically mounted weight end cap 6 and counterweight pull bar 7.Counterweight end cap 3 connects with transmission mechanism by keyway, by screw, with blade 1, connects, and adopts Step Shaft and blade 1 to carry out coaxial positioning.Counterweight pull bar 7 connects with eccentrically mounted weight end cap 6 by joint bolt 5, and eccentrically mounted weight end cap 6 is tightened to realize and the connecting of end-cover axle 4 by joint bolt 5.The end of eccentrically mounted weight end cap 6 is designed with 18 * 18 squares (as accompanying drawing 2) step, spanner is rotating eccentricity counterweight end cap 6 thus, thereby realize the circular motion of counterweight pull bar 7 on transverse plane, eccentricity value is 2mm, can realize that so counterweight pull bar 7 can also be able to improve the integral rigidity of cutter in addition to maize milling cutter dynamically balanced adjusting in the High Rotation Speed situation.
as shown in accompanying drawing 5 and accompanying drawing 6, cutter adopts combining structure, blade 8 is fixed by screws on knife rest 10, can unclamp screw, regulate upper-lower position, also can be when needs sharpening cutter, directly pull down, the anterior angle of blade 10 is 24 °, relief angle is 11 °, knife rest 10 is connected in the cutter groove by screw and alignment pin, blade 8 is being supported in tool rest 11 tops, the butterfly spring 13 of compressive state has been installed in below, spring 13 unclamps in situation heightening screw 9, can automatically hold up tool rest and blade, dish spring locating shaft 12 upper ends can be moved on gathering sill, on blade 8, move simultaneously, the rise maximum is 3mm, so can make up the wearing and tearing of cutter.
The course of work: before carrying out the plank machining, on dynamic balancing machine, maize milling cutter is carried out to experiment of dynamic balancing, 3 eccentrically mounted weight end caps 6 on the adjusting corn milling cutter, until cutter reaches the requirement for dynamic balance under high rotating speed.In working angles, make blade 1 High Rotation Speed, timber is inputted from the translation feeding of cutter below, because cutter distributes in the shape of a spiral, cutter 2 on blade 1 will participate in wood cutting by sword, reach the cutting plank and reduce noise, avoids dust, reduces power consumption and improve the purpose of cutting quality.Cutting timber after a period of time, blade 8 is wearing and tearing gradually, owing in each insert groove, having fixed 2 groups of disk springs 13, when tool wear, that unclamps knife rest 10 upper ends heightens screw 9, and disk spring 13 can be by tool rest 11 top upwards, band cutting blade 8 rises, compensate tool wear, thereby extended the service life of cutter, improved the utilization rate of cutter material.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
