Description
Technical field
The present invention relates to many main spindle numerical controls Drilling operation equipment technical field, particularly relate to a kind of defining method of many main spindle numerical controls sieve plate rig adjacent main distance between axles.
Background technology
Drilling machine refers to the lathe mainly using drill bit machining hole on workpiece.Numerical control drilling machine refers to the position in numerical control positioning hole and the drilling machine of drilling depth.The kind of drilling machine is a lot, divides by version, has radial drill, fixing bench drilling etc.; Divide by main shaft quantity, have single shaft brill, multi-drill etc.; Divide by control mode, have common brill, numerical control drilling; Divide at space position by main shaft, have plane to bore, two dimension is bored, three-dimensional is bored; Divide by purposes, have sieve plate to bore, connect twist drill, flange brill, tube sheet brill, angle steel brill, H profile steel brill etc.; Divide by penetration rate, have common brill, high speed drill; Etc..The kind of drilling machine is very many in a word.What the present invention related generally to is that many main spindle numerical controls sieve plate bores.
Numeric Control Technology is used for drilling machine, and main purpose is used to realize the numerical control positioning of bore position and the digital control processing of drilling depth.Here repeat no more.
Multi-drill is also expressed as Ni Zhifu drill.The special drill press that general multi-drill manufactures and designs when being and producing in enormous quantities for specific workpiece.Relative position between multiple main shafts of general multi-drill and distance are fixing, and the arrangement mode of multiple main shaft has word order, circumferential arrangement, rectangular array etc.Distance in particular cases between multiple main shaft is adjustable, but when main shaft is many, complicated mechanism, if the mechanism of design had both met transmission requirement, meet again the requirement of the spacing of each main shaft of adjustment, such structural design manufacture is not the thing that part easily realizes.
Sieve plate bores, as the term suggests be used to the drilling machine boring sieve plate.Sieve plate is widely used in the industries such as papermaking, pharmacy, environmental protection, food, mine, metallurgy, coal, brick and tile.The feature of sieve plate is:
1, hole embark on journey, layout in column;
2, Kong Duo, close;
3, hole is little;
4, pitch-row requires not strict, and percent opening is not less than the requirement of regulation.
Feature 1 requires that the main shaft that multiaxis sieve plate bores is word order; Feature 2 illustrates that many spindle drillings are very important; The thrust of feature 3 explanation boring, moment of torsion, power are little, facts have proved that small electrical main shaft can meet the demands; When feature 4 illustrates and meets percent opening requirement, pitch-row can suitably adjust.
The Necessity and feasibility of research many main spindle numerical controls sieve plate rig adjacent main distance between axles defining method is further illustrated below according to the above feature of sieve plate.
The sieve plate of sieve plate, particularly papermaking, environmental protection, pharmacy, food service industry, bore diameter generally exists
arrive
between.Sometimes a sieve plate requires to bore a hundreds of thousands hole.Boring be sieve plate processing master operation, be also processing the longest operation consuming time.For the sieve plate in 100,000 holes, if a spindle drilling, process 8 hours every day, general needs 30 days.An obvious spindle drilling efficiency is low, and installing that many main shafts hole simultaneously is raise the efficiency topmost means.
But, install many main shafts hole simultaneously design time there is following problem:
Does is 1, which type of the structure of multiple main shaft?
Is 2, how the spacing between the adjacent main shaft of main shaft multidate determined?
3, to suppose equipment have been installed N number of main shaft, will how many how many small steps of large step N number of main shaft divide to complete the boring of a line?
Generally adopt multiple small electrical main shaft in one line for problem 1, spacing is adjustable.The quantity of the electro spindle that an equipment is arranged and usage quantity are determined by designer and user.For example manufacturer's design and installation 8 electro spindle on an equipment, user can use 8, also can use 2,3 etc.The diameter of small electrical main shaft has
deng.
these 3 kinds of specifications just can meet
arrive
the boring requirement in hole.
The mode adopted at present for problem 2 and problem 3 obtains result by designer by a large amount of calculating, and which results in multiple drill press designing and calculating intricate operation, the design cycle is long.In using, when calculating misses the main points, operative employee also often adopts subregion, burst to hole, instead of the boring of a line a line, and drilling efficiency is low.
Summary of the invention
