Composition graphs 4, feeler mechanism in the present embodiment comprises copying profiling wheel 602 and circular formwork 603, copying profiling wheel 602 is arranged in the adjustment hole 604 on arm-tie 501 by connecting rod, this adjustment hole 604 has two at least, and each adjustment hole 604 is arranged in order along arm-tie 501 length direction, there are 5 specific to the adjustment hole 604 set by the present embodiment.The feeler mechanism side of lathe body 1 is provided with bracket 601, the two ends of circular formwork 603 are provided with regulating tank 605, in regulating tank 605, fastening bolt is housed, circular formwork 603 is fixed on bracket 601 by fastening bolt, and side circular formwork 603 with imitation profile toward the outer side.When reality uses, can according to the position of the position adjustment circular formwork 603 of workpiece 4.In the process that copying profiling wheel 602 moves along circular formwork 603, if the diameter dimension of copying profiling wheel 602 is too small, then fully cannot contact with all of imitation profile, therefore make copying profiling wheel 602 radius be less than minimum curve surface radius on circular formwork 603.
Cutting compensation mechanism 2 in the present embodiment controls copying profiling wheel 602 by arm-tie 501 and coordinates with the imitation profile of circular formwork 603.This cutting compensation mechanism 2 comprises axostylus axostyle 202, outer sleeve 203, outside stage clip 204, gag lever post 206, inner sleeve 208 and inner stage clip 209.Wherein, inner sleeve 208 is fixedly connected with supporting plate 502 outer face, and the screwed one end of axostylus axostyle 202 is threaded with the pair of nut on arm-tie 501 through inner sleeve 208; This is threaded and arm-tie 501 and axostylus axostyle 202 can be made to be synchronized with the movement, and the reach again by screwing in adjusts the outstanding length of axostylus axostyle 202, is convenient to adjustment spring applied force.
Composition graphs 5 and Fig. 6, axostylus axostyle 202 other end is provided with adjustable plate 201, and outer sleeve 203 one end is provided with circular baffle plate, and this baffle plate and adjustable plate 201 fit, outer sleeve 203 other end is sleeved on inner sleeve 208, can relative sliding between outer sleeve 203 and inner sleeve 208.Outer sleeve 203 is equipped with coaxial outside stage clip 204, this outside stage clip 204 one end props up the baffle plate of outer sleeve 203 outer end, outside stage clip 204 other end props up supporting plate 502 outer face, then outside stage clip 204 pairs of axostylus axostyles 202 are applied with power left, make arm-tie 501 have the trend be moved to the left.And then making copying profiling wheel 602 be close to imitation profile, the cutter head 301 on tool rest 3 to be walked out profiling track according to imitation profile, realize copying, and outer sleeve 203 can not affect the adjustment of adjustable plate 201 pairs of lateral feeds.
As everyone knows, the power that spring can provide and the proportional relation of its deformation quantity, namely deformation quantity is larger, and the power provided is also larger.During copying, profiling curved surface is D along the maximum spacing in axostylus axostyle 202 direction, then the maximum length knots modification of process peripheral stage clip 204 is D.If the counteragent of outside stage clip 204 is larger, then copying profiling wheel 602 is when imitation profile moves, copying profiling wheel 602 and imitation profile rub larger, heavier to the wearing and tearing of copying profiling wheel 602 and imitation profile, the wearing and tearing of the bossing especially on imitation profile are the most serious, just cannot continue to use after processing several times, otherwise copying precision can be had a strong impact on.If the counteragent of outside stage clip 204 is less, then cannot provide enough power that copying profiling wheel 602 is fully contacted with the concave arc-shaped section on imitation profile, the machining locus of cutter head 301 is different from the profiling curve of imitation profile, and percent defective improves.Therefore, this problem becomes the technological difficulties in copying process.
In order to solve this for topic, common way is arranged in rational scope by the counteragent of outside stage clip 204, carries out copying when ensureing bite.But find in actual process, when relying on single outside stage clip 204 to carry out copying, when the motion deformation amount of outside stage clip 204 provides enough power more than during 2D/3 by being difficult to, the convex globoidal part wears of imitation profile can be made comparatively serious simultaneously.
Composition graphs 7, for the problems referred to above, the present embodiment offers inner sleeve groove 207 on inner sleeve 208, this inner sleeve groove 207 is primarily of straight line slippage section and engaging section composition, axostylus axostyle 202 is set with coaxial inside stage clip 209, and this inner stage clip 209 one end props up supporting plate 502 outer face, and inner stage clip 209 other end is fixed with circular gag lever post 206, this gag lever post 206 and the clamping of the section of engaging, then inner stage clip 209 cannot apply left to axostylus axostyle 202 counteragent.Engaging section on this inner sleeve 208 is interconnected primarily of inside groove tilting section 2071, inside groove changeover portion 2072 and inside groove arc section 2073 and surrounds.The diameter of inside groove arc section 2073 equals the diameter of gag lever post 206, also can, slightly larger than the diameter of gag lever post 206, be mainly used in blocking gag lever post 206.The lower end of inside groove tilting section 2071 tilts to inside groove arc section 2073, inside groove tilting section 2071 and the length bottom the tie point distance section of engaging of straight line slippage section are less than inside groove arc section 2073 and the length bottom the tie point distance section of engaging of straight line slippage section, namely the upper extreme point on the left of inside groove tilting section 2071 is lower than the lower extreme point on the left of inside groove arc section 2073, and inside groove arc section 2073 is not less than the diameter dimension of gag lever post 206 with the minimum range of inside groove tilting section 2071, the width of straight line slippage section is not less than the diameter dimension of gag lever post 206, then gag lever post 206 both can be connected in engaging section, can linearly slippage section slide again.
In addition, outer sleeve 203 in this enforcement is provided with outer sleeve groove 205, this outer sleeve groove 205 is identical with inner sleeve groove 207 structure, and also comprise straight line slippage section and engaging section, the engaging section of outer sleeve 203 is provided with corresponding water jacket tilting section 2051, water jacket changeover portion 2052 and water jacket arc section 2053.But unlike, the engaging section of outer sleeve 203 is contrary with the engaging section setting direction of inner sleeve 208, make inside groove arc section 2073 relative with water jacket tilting section 2051, when outer sleeve 203 moves, gag lever post 206 is in the switching intersegmental with the engaging of inner sleeve 208 of the engaging section of outer sleeve 203.
When copying profiling wheel 602 moves to the cancave cambered surface on imitation profile, outer sleeve 203 moves upward, gag lever post 206 is connected to inside groove arc section 2073, the straight line slippage section of outer sleeve 203 is in sliding mode relatively simultaneously, because lower extreme point on the right side of water jacket arc section 2053 is higher than upper extreme point on the right side of water jacket tilting section 2051, when outer sleeve 203 moves to 2D/3, on the right side of water jacket arc section 2053, lower extreme point crosses the horizontal middle section of gag lever post 206, water jacket tilting section 2051 contacts with the lower right side arc surface of gag lever post 206, and to its applied thrust; Along with outer sleeve 203 continues to move upward, water jacket tilting section 2051 releases inside groove arc section 2073 gag lever post 206 gradually, when the left side lower extreme point of lower extreme point on the right side of water jacket arc section 2053 directly over inside groove arc section 2073, gag lever post 206 is due to the thrust of the resistance and water jacket tilting section 2051 that are subject to inner stage clip 209, automatic sliding, to water jacket arc section 2053, enters the straight line slippage section of inner sleeve groove 207 simultaneously.The active force of inner stage clip 209 is delivered on axostylus axostyle 202 by outer sleeve 203, then realize the compensation of inner stage clip 209 pairs of cutting force.Owing to completing the switching of gag lever post 206 when being the left side lower extreme point of lower extreme point directly over inside groove arc section 2073 on the right side of water jacket arc section 2053, transition is mild, can not form collision and cause the acute variation of cutting force, not affecting normal machining.
In like manner, referring to Fig. 7, when copying profiling wheel 602 moves to the protruding cambered surface on imitation profile, axostylus axostyle 202 is oppositely hauled by arm-tie 501 and moves downward, and then drive outer sleeve 203 to move downward, when its displacement reaches D/3, on the left of inside groove arc section 2073, lower extreme point is directly over the horizontal middle section of gag lever post 206, inside groove tilting section 2071 contacts with the lower left side arc surface of gag lever post 206, and to its applied thrust; Along with outer sleeve 203 continues to move downward, inside groove tilting section 2071 releases water jacket arc section 2053 gag lever post 206 gradually; When lower extreme point on the left of inside groove arc section 2073 is directly on the right side of water jacket arc section 2053 during lower extreme point, gag lever post 206 is due to the thrust of the resistance and inside groove tilting section 2071 that are subject to inner stage clip 209, automatic sliding is to inside groove arc section 2073, enter the straight line slippage section of outer sleeve groove 205 simultaneously, elimination cutting force compensates, transition is mild, can not form collision and cause the acute variation of cutting force, not affecting normal machining.The counteragent provided due to outside stage clip 204 increases gradually, can not cause the excessive wear of imitation profile local, extend the service life of feeler mechanism.
