Description
Technical field
The present invention relates to a kind of technical field of bore hole, specifically refers to a kind of the different for processing of the non-round surface of processing
The precision boring bar of type hole and the numerical value Boring machine using it, so as to can according to demand produce high accuracy and stable profiled holes.
Background technology
At present, some bear the pin-and-hole of complicated high machinery and thermic load part such as internal combustion engine etc., due to transmitting torque
Bearing pin deformation size it is different and change with the position of stress point, so the ideal form of this kind of pin-and-hole cross section should be oval
Shape, and the change with the difference of profiled holes axial location of the size of ovality, criteria of right and wrong ellipse；The axially element of this kind of pin-and-hole
Line also should be a kind of i.e. usually said " horn mouth " shape of shaped form for meeting bearing pin stress, therefore this kind of pin-and-hole is as designed
For profiled holes such as elliptical aperture, arcuate socket etc. of not rounded, then its bearing capacity can be greatly improved, extend its service life.
And traditional processing special holes, being inclined using main spindle box can only once adjust one fixed ellipse of processing, but
Such processing mode, not only needs the main spindle box for adjusting Boring machine, and it easily causes the interference of boring bar and processed hole, in order to keep away
Exempt from the interference of boring bar and processed hole, it is necessary to reduce the diameter of boring cutter boring bar, this certainly will have impact on the rigidity of boring bar, it cannot be obtained
To stable and high-precision noncircular pin hole, and it cannot realize the processing of non-standard elliptical aperture, unlikely realize other types
Non-circular hole and bellmouth orifice processing；
For this purpose, industry exploitation has special profiled holes boring machine, its structure includes bed piece, and the main shaft installed on lathe bed drives
Galvanic electricity machine, angle of eccentricity measurement apparatus, workpiece clamping mechanism, workpiece locating mechanism, numerical control device, servo longitudinal Motor drive system
System, automatic lubrication installation, spindle drive motor couples with hole throttle type high speed and precision fluid pressure boring head, it is characterized in that in machine
The magnetostrictor chiller of magnetostriction feed mechanism and magnetostriction feed mechanism is installed and with power transmission in bed main shaft
Device, and wherein install linear on front end installation the high frequency sound servo deformable body, and servo longitudinal motor driven systems of boring head
Guide rail vertically moves slide unit.Solving existing boring machine whereby cannot realize that " horn mouth or non-standard oval or its combination " etc. is different
The processing of shaped pin hole.
But, it yet suffers from numerous shortcoming and defect in practical application, and first, it is mainly using change boring machine
Integrated model will so be significantly increased the unstability of boring bar realizing the technology in working special-shaped hole, also reduce boring bar and improve to turn
The probability of speed, while when boring head and feed mechanism is driven, with greater need for larger load, it is not intended to the consumption of a raising energy.
Separately, the main shaft of the boring machine adopts belt transmission, it is impossible to avoid causing machine vibration because of belt shudder；Not only increased failure
Source, and increased the parameter of processing surface roughness.What is more, because aforesaid aggregation problem, it can be only done single operation,
To operations such as pin-and-hole bellmouth orifice, interior chamfering, outer chamferings, needs are completed on other bed specials, not only increase resetting mistake
Difference, so as to affect the precision of overall processing.
In other words, above-mentioned the deficiencies in the prior art how are overcome, there is provided a kind of high accuracy and stable processing special holes,
And the irregularly-shaped hole process technology of various kenels can be realized, it is the epochmaking problem of current industry.
