Detailed description of the invention
Below in conjunction with the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of intelligent machine arm for processing three-eccentric-butterfly-valve, comprise PLC, slide block 1, knife bar 2, supporting seat 5, reductor 10, servomotor 11, track base 13, knife rest 14, base 15 and dust cap 16, one end of knife rest 14 is provided with knife bar 2, the other end connects ball-screw 4 by nut 3, dust cap 16 is installed in the top of knife rest 14, the below of knife rest 14 is fixed on the slide block 1 on track base 13, track base 13 is by base 15 connecting support seat 5, one end of supporting seat 5 connects ball-screw 4, the other end connects servomotor 11 by reductor 10, also successively by back-up ring 7 on supporting seat 5, stop washer 8, round nut 9 installs shaft coupling 12, PLC is also connected with servomotor 11.
According to three-eccentric-butterfly-valve figure paper size, when calculating main shaft rotation, the point on sealing surface is along the rate curve of knife rest 14 cutting direction; Curve program is inputted PLC, thus control servomotor 11 drives ball-screw 4 to rotate, promotion nut 3 and slide block 1 move back and forth along track base 13, realize knife rest 14 and rotate by the rate curve of regulation.
The present invention is fixed on the original knife rest of lathe, allow knife rest drive intelligent machine arm, complete tool feeding together, its intermediate slide is by the uniform velocity feeding, intelligent machine arm by the rate curve feeding calculated, thus realizes cutter and carries out continuous cutting along sealing surface to valve body or valve plate always.Concrete scheme as shown in Figure 2.
