The specific embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.
The pneumatic material mechanism of pulling out that is used for Digit Control Machine Tool, has pedestal 1, being shaped on step-like piston cavity 9 and one end in the described pedestal 1 seals with end cap 6, the shape of piston 2 and step-like piston cavity 9 suitable and included formation air chamber I 10 and air chamber II 11, described piston 2 other end end faces are shaped on groove II 8, described air chamber I 10 with advance/go out gas circuit I 12 and be communicated with, described air chamber II 11 with advance/go out gas circuit II 13 and be communicated with, described piston 2 one ends are shaped on a screwed hole and push rod 8 screws, the both sides that described push rod 8 other ends stretch out cavity all are shaped on allocating slot 14, described pedestal 1 other end is shaped on fluting 15, it is interior and hinged with pedestal 1 that material pawl I 3 and material pawl II 4 are all included fluting 15 in, concrete, described fluting 15 bottoms are shaped on the groove I 7 of dodging piston 2, and it is interior and hinged by rotating shaft 5 with pedestal 1 that described material pawl I 3 and material pawl II 4 are all included fluting 15 in.Described material pawl I 3 and material pawl II 4 one ends form the clamp port 17 of holding workpiece 16, and the shift fork 18 of material pawl I 3 and material pawl II 4 other ends is all included in the allocating slot 14.Push rod 8 is threaded with piston 2 usefulness, and rotation push rod 8 can be regulated it and add and hold mouthful 17 sizes, and the size variation of clamp port 17 can adapt to the clamping of the blank rod of different-diameter.The shift fork 18 of material pawl I 3 and material pawl II 4 other ends is all included in the allocating slot 14.
During work, gas enters air chamber I 10 from the gas circuit 12 of advancing/go out of piston 2 right-hand members, promoting piston 2 is moved to the left, thereby make piston 2 promote material pawl I 3 and material pawl II 45 rotations around the shaft, the clamp port 17 of material pawl I 3 and 4 formation of material pawl II increases, and drives this pneumatic pulling out by lathe programming instruction control machine tool dragging plate knife rest and expects that mechanism moves to the correct position of blank bar; When gas enters air chamber II 11 from the gas circuit II 13 of advancing/go out of piston 2 left ends, promoting piston 2 moves right, thereby make piston 2 promote material pawl I 3 and material pawl II 45 rotations around the shaft, the clamp port 17 that material pawl I 3 and material pawl II 4 form dwindles, make material pawl I 3 and material pawl II 4 clamping work pieces 16, then the collet on the machine tool chief axis unclamps the clamping to the blank bar, by machine tool dragging plate and knife rest this pneumatic material mechanism of pulling out is vertically moved, take the blank bar out of to suitable technology position, collet on the main shaft clamps the blank bar then, gas enters air chamber I 10 from the gas circuit 12 of advancing/go out of piston 2 right-hand members, promote piston 2 and be moved to the left, piston 2 promotes material pawl I 3 and material pawl II 45 is rotated around the shaft, and the clamp port 17 that material pawl I 3 and material pawl II 4 form increases, unclamp the blank bar, the origin-location is return by this pneumatic material mechanism of pulling out.Wherein, this pneumatic material mechanism of pulling out can be installed on the knife rest of machine tool dragging plate, by the motion of machine tool dragging plate, finishes the feeding of lathe, but is not limited to be installed on the lathe supporting plate.
