Axial is earthed up forest assemble discuss

Advanced machine of a few tools is exhibited in, I ever saw certain manufacturer uses hollow ball screw, use means of in-house oily cold loop to control temperature rise, this design is so-called at that time must not add outfit optics feet to be able to achieve same precision requirement, charge holds optical feet petty gain than adding again, but what make a person feel puzzled very much is, why to see each manufacturer is used extensively later, whether spare parts or use on unbeknown problem exists, our have no way understands.

And the main transfer machinery of " of " linear motor that develops in recent years, also be to flaunt write " not to have a back unoccupied place, the catchword of 0 errors " , but its locate the system still is to use optical feet to detect means, nevertheless, because this new technology still is in development, do not grant to discuss here.

So, machine stage installs optical feet to remain tool machine industry eliminates heat to change now, most the functional project that often uses.

Axial screw is earthed up now forest type of group cubic metre, great majority is to use one aspect of the matter to press the installation method that reachs another end to be pulled beforehand beforehand, its combination, does haply have below does graph place show: ?  of Fu of word willful ぞ raiseds paths between fields び Mei mires banyan watersides sunlight? approachs end beforehand is DB normally model or it is FFB model, pull end to use DT beforehand model, it is the most general that this kind of method can say, and structural installation is easy, come to those who bring about intermediate prolapse because length is too long,can reduce ball screw change model quantity, 2 will can change heat beforehand again model the value is reduced to the rate that can accept, but, "Pull value " to want to be pulled after all beforehand, just won't be earthed up to axial forest, all the time since neither one cuts data to be able to offer reference truly, it is to rely on the feel experience of experienced worker to judge more very previously, regular meeting has the problem with power uncontrollable volume, once used later controallable the torsional spanner of force goes locking pulls screw cap beforehand, but the case that defends burn down of Xiang Peilin of solid period internal shaft is visible still, until in last few years, benefit dosage expresses corrective ball screw to assemble the way that plays a worth beforehand, just be able to beg a locking to change model quantity and pull stretchy safe limits to be worth beforehand.

And earth up Lin Shou life to also extend the client's acceptability reasonable fixed number of year.

Nevertheless, if have a company to produce Xiang Peilin of manufacturing CNC lathe and M/C center crankshaft all sorts of differring assemble means and norms amount, still a few places can offer everybody discussion research. One, without pull fashion group to stand beforehand (old model, already stop production) TNS-0WX/Z axis TNS-1X/Z axis TNS-2X/Z axis TNS-3X/Z axis TNS-5X/Z axis axis of V-65/80X/Y/Z of axis of V-4X/Y/Z axis VM-5X/Y/Z 2, motor end is servo to be pulled beforehand group establish V-36/46X axis 3, motor end is servo to be pressed beforehand group establish ME/MP/P1/MS/S1/S2/MX/MY/Y1/V-16/20/26X/Z axis axis of V-36/46Z axis V-55/70/80/85/102/105/125/130/140/145/205X/Y/Z is pressed beforehand upright group stands beforehand, above graph is exemple, pull beforehand when ball screw when screw cap begins locking, criterion every average force that trains Lin Cheng to suffer always closes for: Fa=Fb+Fc+Fd is earthed up namely forest force of A place press press may be earthed up for other forest 3 times tall, simple e.g. , weight of hypothesis bed stage is 300kg, fast and floating rate is axial 30 meters / cent, 0-30 rice quickens time 0.

12sec, according to Shi Li formula calculates: Vb=Va+at, ) of Va=0(initial velocity, vb=30/60=0.

5(rice / second) , t=0.

12(second) (quicken time) 0.

5=0+a*0.

12, a=4.

16(acceleration) F=ma=300*4.

16=1250*9.

The graph below 8=12250(N) looks to earth up the opposite location drawing of Lin Shouli and deflection (NACHi catalog offers) , if have machine stage to pull a value to be 5-10 beforehand (according to different type character) , criterion machine stage is when static condition, axial is earthed up forest the pressure that has borne to be equivalent to locomotive condition, add resistance of stage of bed of the cutting when the machine machines movement, earth up forest service life and precision requirement, will get because of this test. After afore-mentioned integratedly discussion, roughly but classify gives the following result that figure a drop: 1.

Should pull beforehand with press beforehand earth up forest group stand when direction and amount are unequal, each are earthed up forest what get force bulk also not identical, the amount is less time of Duan Peilin service life, because the meeting bears greater pressure and reduce, even in advance attaint. 2.

Compare lathe and milling machine each axis is earthed up forest after amount and type of group cubic metre, can discovery arrives to among them very big difference existence; is opposite for major lathe, x/Z axis presses end to earth up Lin Ke number and norms beforehand, want many than playing end beforehand one reachs Dashangyi class size, this kind of design has compared with milling machine apparently different, earth up Lin Gengneng to bear quite heavy cut place arises cross bear pressure, and service life is longer. 3.

Ball screw heat changes when, because earth up forest assemble structural character, screw cannot to approach fixed end beforehand extend, must go to pull beforehand earth up forest direction is outspread, then axial locates precision, go to more pull directional size to forbid more beforehand, this phenomenon reachs axis of Z of M/C milling machine to axis of CNC lathe X for, because machine the position to be mostly near ball screw tail end, the client often reacts fixed position precision is met because of cold heat engine differ somewhat; so, if will press upright instead beforehand gadarene installation method, machine arbor to lathe X axis kind the beard such as workpiece wants precision of high fixed position to ask to look, do not need feet of additional installation optics to be able to improve the problem with flabby dimension considerably. 4.

Because pull end to be able to have hot splash beforehand,go up stretchy phenomenon, if servo motor wants to install,carry the position at be being pulled beforehand when, had better be to use the shaft coupling that circle a gender, or it is the combinative orgnaization that other can absorb this deflection. 5.

Reach axis of Z of M/C milling machine in the light of axis of CNC lathe X for, because axial is earthed up forest must want commanding officer of tower of extra burden knife the weight with main shaft head, assemble this issue must consider on the design, and centre of gravity of production of prospective machine stage changes a function in high speed and much axis, car / compound machine added mill more Y axis weight, m/C machine is planted face is not had deserve to weigh directional design, can increase earth up forest heavy load and change model, but be revised according to existing machine stage again add outfit, can bring about exceed the limit that designs ability formerly, generation does not stabilize an element, cause spot matched stack corrective the problem with after service, can saying is pull one hair and move systemic; accordingly, want how to be revised, remain each unit discussion will sum up!
