Description
Technical field
The present invention relates to many main spindle numerical controls Drilling operation equipment technical field, particularly relate to a kind of many main spindle numerical controls sieve plate and bore
The determination method of hole equipment adjacent main distance between axles.
Background technology
Drilling machine refers to mainly process on workpiece the lathe in hole with drill bit.Numerical control drilling machine refer 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.；By main shaft quantity
Point, there are single shaft brill, multi-drill etc.；Divide by control mode, have common brill, numerical control drilling；Divide at space position by main shaft, have flat
Face is bored, two dimension brill, three-dimensional brill etc.；Divide by purposes, have sieve plate brill, couple twist drill, flange brill, tube sheet brill, angle steel brill, H profile steel brill
Deng；Divide by penetration rate, have common brill, high speed drill；Etc..The kind of drilling machine is the most in a word.The invention mainly relates to
It 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 of the numerical control positioning of bore position and drilling depth
Processing.Here repeat no more.
Multi-drill is also expressed as Ni Zhifu drill.It is special that general multi-drill manufactures and designs when being and produce in enormous quantities for specific workpiece
Drilling machine.Relative position and distance between multiple main shafts of general multi-drill are fixing, and the arrangement mode of multiple main shafts has a word
Arrangement, circumferential arrangement, rectangular array etc..Distance between the most multiple main shafts is adjustable in, but when main shaft is many,
Complicated mechanism, if the mechanism of design had both met transmission requirement, meets again the requirement of the spacing adjusting each main shaft, this
It is not the thing that easily realizes of part that the structure of sample manufactures and designs.
Sieve plate bores, as the term suggests being used to bore the drilling machine of sieve plate.Sieve plate be widely used in papermaking, pharmacy, environmental protection, food,
The industries such as mine, metallurgy, coal, brick and tile.The feature of sieve plate is:
1, hole is embarked on journey, is arranged 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 the most necessary
's；The thrust of feature 3 explanation boring, moment of torsion, power are little, in practice it has proved that small electrical main shaft can meet requirement；Feature 4 is said
Bright meet percent opening requirement in the case of, pitch-row can suitably adjust.
Above feature below according to sieve plate further illustrates research many main spindle numerical controls sieve plate rig adjacent main between centers
Away from the Necessity and feasibility determining method.
Sieve plate, particularly papermaking, environmental protection, pharmacy, the sieve plate of food service industry, bore diameter typically existsArriveIt
Between.Sometimes require on a sieve plate to bore hundreds of thousands hole.Boring is the master operation of sieve plate processing, is also that processing is time-consumingly the longest
Operation.As a example by the sieve plate in 100,000 holes, if a spindle drilling, process every day 8 hours, general needs 30 days.Aobvious
A right spindle drilling efficiency is low, and installing many main shafts and holing simultaneously is to improve the topmost means of efficiency.
But, install many main shafts hole simultaneously design time there is problems in that
1, which type of the structure of multiple main shafts is？
2, how the spacing between main shaft multidate neighbour main shaft determines？
3, assume on equipment, to be mounted with that N number of main shaft, N number of main shaft to divide several a few small step of big step to complete the boring of a line？
Typically using multiple small electrical main shaft in one line for problem 1, spacing is adjustable.The electricity arranged on one equipment is main
Quantity and the usage quantity of axle are determined by designer and user.For example 8 electricity of manufacturer's design and installation on an equipment
Main shaft, user can use 8, it is possible to use 2,3 etc..The diameter of small electrical main shaft has Deng.These 3 kinds of specifications just can meetArriveThe boring in hole
Requirement.
The mode used at present for problem 2 and problem 3 is to obtain result by designer by substantial amounts of calculating,
Which results in multiple drill press design evaluation work loaded down with trivial details, the design cycle is long.In using, when calculating misses the main points, operative employee is also
Often using the boring of subregion, burst rather than the boring of a line a line, drilling efficiency is low.
