Move back and forth track around the generation of modular ring nonlinear curve slot by fourth bearing 21.
It is 1 with 19 reduction ratio of gear shaft that workpiece 4 to be processed, which has N square hole structures, ring gear 13,：N, N=4,6,8 are that is, interior
Gear ring 13 1 circle of rotation, gear shaft 19 under the revolution action for the connecting rod 5 being secured to rotate N circles.The groove of the modular ring 36 is bent
Line is Symmetric Nonlinear groove line, and the range difference of each point to center is equal on N square holes face each point in itself in groove line
The range difference of the heart, the distance of groove minimum point to center and the difference at a distance from peak to center are equal to N square holes angle
Difference at a distance from the distance of center and side center line to center.I.e. under the rotation of modular ring 36 drive, in groove
Connecting shaft 25 by fourth bearing 21 around non-linear groove revolution realize move back and forth, and then realize N square holes face on each point
The distance set to center, each point link up as a line, with crust of the device 6 under the feeding of lathe supporting plate 7 by
Line forms the face of N square holes.
By the reduction ratio of change ring gear 13 and gear shaft 19, point quantity such as changeable irregularly-shaped hole is formed, for example set
Reduction ratio is 1：6, irregularly-shaped hole is six deciles；Reduction ratio is set as 1：4, irregularly-shaped hole is the quartering；Reduction ratio is set as 1：8, it is different
Shape hole is eight equal portions, and so on.By changing modular ring inner groovy nonlinear curve, square hole, hexagonal hole, all directions can be generated
Hole etc., such as the inner groovy curve by measuring the modular ring that the range difference of each point to center on one face of hexagonal hole is formed,
Hexagonal hole can be formed by the tangent revolution with the curve.Similarly, reduction ratio is set as 1：4, by measuring one face of square hole
The inner groovy curve for the modular ring that the range difference of upper each point to center is formed, four can be formed by the tangent revolution with the curve
Square hole, and so on.
By taking turning hexagonal hole as an example, the utility model truning fixture process is：It is clamped on scroll chuck 2 to be processed
Workpiece 4 turns round while driving link block 3 and connecting rod 5 to turn round, and connecting rod 5 drives the ring gear 13 of connection fixed thereto to turn round and pass through
Rotating ratio 1：6 realize 19 underdrive of gear shaft, and the rotation of gear shaft 19 drives modular ring 36 to turn round, and is further converted into and passes through mould
What non-linear groove in ring 36 formed connecting shaft 25 moves back and forth action, and passes to and 25 fixed connecting seat 23 of connecting shaft
With mobile knife bar 9, formed with 4 interpolation of workpiece of revolution to finally realize that the cutter head 8 being fixed on mobile knife bar 9 moves back and forth
Hexagon, and form hexagonal hole under the feed motion of lathe supporting plate 7.
As Fig. 5 (1) -5 (12) show the utility model truning fixture processing hexagonal hole schematic diagram.Movement locus is the 4th
The position of 21 place modular ring of bearing is opposite with modular ring marker location, i.e., fourth bearing 21 is set in modular ring lowest point and corresponds to six
The peak of square hole i.e. the angle of hexagonal hole, fourth bearing 21 are set in the minimum point that modular ring peak position corresponds to hexagonal hole
The namely midpoint in the face of hexagonal hole.That is one circle of ring gear rotation, one circle of hexagonal hole workpiece rotation, and 6 circle of modular ring rotation.
Each side of the above citing irregularly-shaped hole is straight line, when each side of irregularly-shaped hole is not straight line but curve, such as quincunx,
The symmetrical curves irregularly-shaped hole such as ellipse, diamond shape, equally applicable principles above determine reduction ratio according to irregularly-shaped hole isodisperse, measure
Curve each point is modular ring inner groovy curve to center range difference, can all form required irregularly-shaped hole.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
