The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1 and Figure 2, pipe of the present invention is cut the cutter sweep in machine, comprise frame 1, in frame 1, be provided with for the round cutter 2 of cutting pipe and the drive unit that drives cutting knife 2 to rotate, the position that described frame 1 is positioned at cutting knife 2 belows is provided with for positioning tube and guarantees the positioner that pipe can rotate.Introduction is below individual simple in structure, the positioner of good positioning effect.Described positioner comprises that two with the baffle plate of half slot---right baffle-plate 3 and right baffle plate 4, after right baffle-plate 3 and right baffle plate 4 are combined, two half slots just form a pore 5 suitable with tube outer diameter, wherein the right side of right baffle plate 4 is provided with for promoting right baffle plate 4 and the thrust unit that right baffle-plate 3 is combined, and promotes right baffle plate 4 and moves left and right.Right baffle-plate 3 is fixed in frame 1, and the position that right baffle-plate 3 and right baffle plate 4 are positioned under cutting knife 2 is respectively arranged with a cutting knife groove 6 that holds cutting knife 2 cutting pipes.Wherein, described thrust unit comprises the screw rod 7 being threaded with frame 1, and one end of screw rod 7 and right baffle plate 4 are rotationally connected, and the other end of screw rod 7 is provided with driving lever 8.Driving lever 8 rotates for stirring screw rod 7.
As shown in Figure 3, in order to guarantee the accuracy of pipe when rotating and smooth and easy, on described right baffle-plate 3 and right baffle plate 4, be respectively arranged with two gathering sills that communicate with half slot 9, in gathering sill 9, be respectively arranged with and can move and the support 10 that cannot rotate along gathering sill 9, on support 10, be hinged with roller 11, the axis of the axis of roller 11 and pore 5 is in same plane, roller 11 offsets with the outer wall of pore 5 interior pipes respectively, on support 10, be provided with guide post 12, the bottom of gathering sill 9 is provided with spring groove 13, one end of guide post 12 is connected with support 10, when the other end stretches out from the bottom of spring groove 13 and this end is provided with boss 14(actual production, can replace boss with nut), boss 14 is against on the outer wall of baffle plate, on guide post 12, be arranged with spring 15, the bottom of one end of spring 15 and spring groove 13 offsets, the other end and support 10 offset, guide post 12, the center of roller 11 center and pore 5 in a straight line.
Described drive unit comprises by bearing and rotates the driving shaft 16 being arranged in frame 1, cutting knife 2 is fixed on one end of driving shaft 16, the other end of driving shaft 16 is provided with driven pulley 17, in frame 1, be also provided with motor 18, on the output shaft of motor 18, be provided with driving wheel 19, between driving wheel 19 and driven pulley 17, by belt (not shown in FIG.), be connected.
