Introduce a kind of high speed AC pivot angle milling head below, this high speed AC pivot angle milling head contains the corner locating mechanism of organic frame 7 and above-mentioned high speed AC pivot angle milling head, frame 7 is fixed on outside C rotation axle sleeve 1 and floating ring 2, this high speed AC pivot angle milling head contains the driving mechanism for driving C rotation axle sleeve 1 to rotate, two limit switches 5 are all fixedly connected with frame 7 with this driving mechanism, this driving mechanism can be servomotor, as shown in Figures 1 to 4.This high speed AC pivot angle milling head is also containing control unit, limit switch 5 is contact switch, two limit switches 5 are all connected with this control unit with this driving mechanism, and when collision block 4 triggers limit switch 5, this control unit can control this driving mechanism to be stopped driving C rotation axle sleeve 1 to rotate.
C pivot angle is realized from 400 ° to-400 ° spacing courses of work that turn clockwise below with the corner locating mechanism of this high speed AC pivot angle milling head.
Now, the central angle alpha of two limit switches 5 corresponding on floating ring 2 is 60 °, central angle corresponding to first arc groove 11 is 180 °+20 °-10 °=190 °, and the central angle corresponding to the second arc groove 21 is 270 °+40 °=310 °, as shown in Figure 7 to 9.Wherein interior camber line represents the length of the first arc groove 11 on C rotation axle sleeve 1, and outer camber line represents the length of the second arc groove 21 on floating ring 2.Only that make the first arc groove 11 and the second arc groove 21 lay respectively on two circles, actual conditions are that the first arc groove 11 and the second arc groove 21 should be positioned on same circle for the ease of observing and illustrating as shown in Figure 7 to 9.
First, as shown in Figure 7, the first arc groove 11 and the second arc groove 21 are all positioned at initial position, and draw key 3 is positioned at the position of 20 °, and two limit switches 5 are respectively the position of 60 ° and 90 °, and this position is as C pivot angle 400 ° of positions.
Then, the first arc groove 11 and the second arc groove 21 together rotate 300 ° in the direction of the clock, and as shown in Figure 8, the first arc groove 11 forwards 400 °-300 °=100 ° positions to result.Now, the collision block 4 outside the second arc groove 21 touches limit spring, and due to spring thrust effect, collision block 4 brought into temporary contact is less than limit switch 5.
Secondly, the first arc groove 11 continues to turn clockwise, and draw key 3 just starts to slide on the first arc groove 11 and the second arc groove 21.When after the length that draw key 3 covers the first arc groove 11 and the second arc groove 21, first arc groove 11 and the second arc groove 21 will be blocked, no longer can produce relative rotation between first arc groove 11 and the second arc groove 21, second arc groove 21 touches limit switch 5 after driving collision block 4 Compress Spring, in the process, first arc groove 11 together rotates 500 ° clockwise, and this position is C pivot angle-400 ° of positions, as shown in Figure 9.So just realizing C pivot angle turns clockwise spacing from 400 ° to-400 °, from-400 ° to 400 °, principle is the same counterclockwise.
If need C rotation axle sleeve 1 to rotate other angle, the position of the arc length and limit switch 5 that also can pass through change first arc groove 11 and the second arc groove 21 realizes.
The above; be only specific embodiment of the utility model, the scope of utility model enforcement can not be limited with it, so the displacement of its equivalent assemblies; or the equivalent variations to do according to the utility model scope of patent protection and modification, all still should belong to the category that this patent is contained.In addition, the technical characteristic in the utility model and all can using by independent assortment between technical characteristic, between technical characteristic and technical scheme, between technical scheme and technical scheme.
