The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Figure 1, the utility model comprises pay-off 1 and feeding device 2, and pay-off 1 is arranged on the inside pedestal of numerically controlled lathe 3, between feeding device 2 and numerically controlled lathe 3 retaining elements, by dovetail groove and the axis of guide, is connected.
As shown in Figure 2, pay-off 1 forms by capturing the material catching apparatus 11 of part and the drive unit 12 that can drive material catching apparatus to carry out positive and negative 180 ° of rotations, material catching apparatus 11 is arranged on drive unit 12 tops, and drive unit 12 bottoms arrange mount pad 13, and mount pad 13 is fixed on numerically controlled lathe 3.Material catching apparatus 11 is mechanical arm, guide cylinder 111 and pneumatic three-jaw 113, consists of, and pneumatic three-jaw 113 is installed on the end of the guide post 112 of guide cylinder 111, and guide cylinder 111 bottoms are connected with drive unit 12.
As shown in Figure 3, drive unit 12 comprises fixed head 124, connecting key 123, rotating shaft 122 and rotary cylinder 125.Guide cylinder 111 is bolted on the fixed head 124 of drive unit 12, rotating shaft 122 is connected with fixed head 124 by connecting key 123, described rotating shaft 122 is connected with rotary cylinder 125 output shafts, rotating shaft 122 outer setting angular contact ball bearings 121, rotary cylinder 125 is fixed on mount pad 13.
As Figure 4-Figure 6, feeding device 2 comprises for laying putting hopper 21 and part can being pushed to the material-pulling device 22 of mechanical arm of part, puts hopper 21 and be fixed on material-pulling device 22.The cell wall of putting hopper 21 1 sides is provided with tuning screw 211, can by tuning screw 211, adjust the width of putting hopper according to part length, after adjusting to the right place, tuning screw is locked.
Material-pulling device 22 comprises V-type groove 221, bin substrate 223 and holder 225, puts hopper 21 and is fixed on V-type groove 221, and V-type groove 221 is installed on bin substrate 223 and connects by dovetail groove, and V-type groove 221 ends are provided with pusher cylinder 226.V-type groove 221 comprises vertical panel 228 and is positioned at the connecting plate 229 of vertical panel one side roof part to vertical panel lopsidedness, the angle of connecting plate 229 tops and horizontal plane is 10 °-15 °, putting hopper 21 is fixed on connecting plate 229 parallel with connecting plate top, therefore put hopper 21 and also become the angle of 10 °-15 ° with horizontal plane, described vertical panel 228 opposite sides are provided with adjusting screw(rod) 222, can adjust V-type groove 221 front and back by adjusting screw(rod) 222 and slide so that part is positioned.Described holder 225 is positioned at bin substrate 223 bottoms, is provided with the axis of guide 227 that can slide up and down between described holder 225 and bin substrate 223, and holder 225 is provided with the handle 224 of the controlled system guiding shaft extension contracting height being connected with the axis of guide.
