Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, a kind of cutting-tool angle provided by the invention adjusts compensation arrangement automatically, comprise base 1, a riser 2 is fixedly connected with in the side of described base 1, described riser 2 is provided with first curved groove 5, and described riser 2 connects a cutter 3, and described cutter 3 can rotate to an angle around A point, described cutter 3 is connected in described first curved groove 5 at A point place's connection first adjusting pin 8, first adjusting pin 8.
Described base 1 is also flexibly connected a movable plate 4, described movable plate 4 is also connected on the linear input unit of locomotive, described cutter 3 is arranged between described riser 2 and movable plate 4, described movable plate 4 is respectively equipped with the second curved groove 6 and the 3rd curved groove 7, second curved groove 6 is connected with described first adjusting pin 8 corresponding matching, at B point place's connection second adjusting pin 9 that described cutter 3 is crossing with described 3rd curved groove 7, described second adjusting pin 9 corresponding matching is connected in described 3rd curved groove 7.
Described first curved groove 5 and the 3rd curved groove 7 are deep-slotted chip breaker, and the second curved groove 6 is straight-line groove, and described first curved groove 5 and the second curved groove 6 arranged in a crossed manner.Described first adjusting pin 8 and the second adjusting pin 9 are straight pin, first adjusting pin 8 contacts with the two side of the second curved groove 6 with the first curved groove 5 respectively and coordinates, and the first adjusting pin 8 can move freely in the first curved groove 5 and the second curved groove 6, described second adjusting pin 9 contacts with the two side of the 3rd curved groove 7 and coordinates, and the second adjusting pin 9 can move freely in the 3rd curved groove 7.
This adjustment compensation arrangement is interacted by the first curved groove 5, second curved groove 6 and the 3rd curved groove 7 and realizes, and when the some A of cutter 3 on it rotates, point of a knife 3a can produce position and offset on the radial direction of workpiece and the short transverse of axis of workpiece.In order to compensate the skew of point of a knife 3a position, cutter 3 must move while rotating around an A, and this moves is that A point is realized by the first moving of curved groove 5 fixing and bending along.The position of the point of rotation A of cutter 3 processes a hole, and the first adjusting pin 8 is worn and is placed in this hole and the first curved groove 5, and therefore, when the first adjusting pin 8 moves along the first curved groove 5, the some A on cutter 3 will move along the first curved groove 5.Second curved groove 6 is arranged on the movable plate 4 of linear input, and the first adjusting pin 8 is also worn and is placed in the second curved groove 6, its objective is mobile first adjusting pin 8.When the second curved groove 6 does Linear-moving relative to the first curved groove 5, the first adjusting pin 8 will move the point of a knife 3a position deviation compensating and cause because cutter 3 rotates around A point along the first curved groove 5.In order to change cutter 3 anglec of rotation, the movable plate 4 of linear input devises the 3rd curved groove 7, and the some B place on cutter 3 is moved along the 3rd curved groove 7 by the second adjusting pin 9.In order to obtain cutter 3 inclination angle of expecting, there is inherent contacting between the second curved groove 6 and the 3rd curved groove 7, its reason is the position of the A point of B point location-dependent query on the second curved groove 6 on the 3rd curved groove 7.
As shown in Figure 2, the design of the first curved groove 5: the effect of the first curved groove 5 is used to the point of a knife 3a position offset compensated, design in the following manner: when cutter 3 is spent around an A rotation alpha, the opposite direction that it can make A point offset along point of a knife 3a position moves identical distance, that is: the angle of inclination rotation alpha degree of cutter, point A equals in same angle [alpha] point of a knife 3a side-play amount R in the displacement in x direction, it is departure H on the nose height that causes of α that the distance of movement in the Y direction equals the anglec of rotation.Therefore, the track of curve 1 is just consistent with radial misalignment R, height tolerance H, and its equation can be expressed as:
X(α)＝-R＝-[D/2*sinα+L(1-cosα)]
Y(α)＝-H＝-[Lsinα+D/2(cosα-1)]
The design of the second curved groove 6: the effect of the second curved groove 6 is that an A is moved along the first curved groove 5.As shown in Figure 2, second curved groove 6 is designed to the straight-line groove of an inclination, owing to being that the Linear-moving of the second curved groove 6 moves in the first curved groove 5 to order about A point on cutter 3, require that the height in the second curved groove 6 vertical direction must be greater than the height tolerance of point of a knife 3a.Second curved groove 6 minimum length L
1determine the distance that mechanism linearly inputs, its value can be expressed as follows:
L
1＝H
+/tanω+H
-/tanω
In formula: the inclination angle of ω-curved groove 2;
H
+the maximum that-nose height deviation is positive;
H
-the maximum that-nose height deviation is negative.
The design of the 3rd curved groove 7: the effect of the 3rd curved groove 7 makes B point mobile A point is mobile while, and obtain the angle of inclination of expection.By determining that B point obtains the 3rd curved groove 7 relative to the position of putting A on the second curved groove 6.According to Fig. 2, the equation of the 3rd curved groove 7 can be expressed as:
X(α)＝L
2-L
a-L
b
＝L
2(1-cosα)-[Lsinα+D/2(cosα-1)]/tanω
Y(α)＝L
c
＝H+L
2sinα
＝(L+L
2)sinα+D/2(cosα-1)
The equation of the 3rd curved groove 7 can be understood as: the A point when curved groove 2 moves on cutter moves along the first curved groove 5, when A point a certain determine position time, the angle that need be rotated along the height of the first curved groove 5 movement and the distance of level to try to achieve now cutter with formula by A point, for obtaining the required cutter anglec of rotation, B point on cutter relieving moves to a point determined, need meet this point with the distance of the line of mobile rear A point is L
2, equal the cutter anglec of rotation of expecting with the angle of horizontal direction.
Second curved groove 6 and the 3rd curved groove 7 are designed on movable plate 4, along with movable plate 4 moves forward and backward.When movable plate 4 moves, realize the change at cutter 3 angle of inclination, while itself and the first curved groove 5 acting in conjunction make cutter produce angle change, the cutting point of cutter 3 still can not change position on the axis of workpiece, to reach rational cutting ability.
