The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1 and Figure 2, three-shaft steel tube intersecting line cutting machine of the present utility model is installed is comprised the main spindle box 1 that is positioned at cutting machine one end, main spindle box 1 connects rotating chuck 2, steel pipe 9 ends are carried out clamping and the revolution active force is provided, foundation of incision machine track 6 is provided with some steel pipe bracing frames 5, be used for steel pipe 9 is supported, it is little that its head bearings can make steel pipe turn round steady resistance; On base top, be positioned at the height of rotating chuck 2; be parallel to base track 6 and be provided with the crossbeam 4 close with fuselage length; be supported on the base by support 8; cutting head motion assembly 3 can be on the guide rail of crossbeam 4 horizontal sliding; pipeline by roller chain 7 internal protections and power section and control section realize dynamic and electrical connections; cutting head motion assembly 3 comprises and cuts a longitudinal moving mechanism 100, cutting head Lift Part 200, cutting head tilting member 300; can clamping flame or plasma cutting gun 10, steel pipe is carried out cutting processing.At first steel pipe 9 is placed on the steel pipe bracing frame 5 during work, with the extremely correct operating position of cutting head Lift Part 200 liftings, clamp steel pipe one end and rotation by rotating chuck 2, by control system to the rotating chuck 2 of main spindle box 1, cut this three jointly controls of a longitudinal moving mechanism 100 and cutting head tilting member 300, reach to different tube diameters the high accuracy cutting of split requirements such as different straight lines, camber line, intersection.

As shown in Figure 3, Figure 4, the longitudinal moving mechanism 100 of cutting of the present utility model adopts and colludes on the hanging guide rail 401 that is loaded on crossbeam 4.The front of header board 103 is used to install cutting head Lift Part 200, the top and the bottom, back are connected with the vertical straight edged surface of base plate 109 with right angle top board 104, offer some installing holes on the straight horizontal edged surface of top board 104 and base plate 109, two fixed axis 105, two eccentric shafts 107 of installed inside are installed in four installing hole outsides of top board 104, and two axles 106 are installed in inner two holes of top board 104 right angle faces; Horizontal bearing 108 is installed respectively on fixed axis 105, the eccentric shaft 107, vertical bearing 114 is installed on the axle 106; Same base plate 109 horizontal planes have three installing holes, and a fixed axis 105 is installed in the outside, and two eccentric shafts 107 of installed inside are installed horizontal bearing 108 respectively, and two axles 106 are installed in inner two holes, and vertical capacity eccentric bearing 114 is installed.Laterally the outer collar of bearing 108 and vertical bearing 114 contacts with last bottom surface with the side of the guide rail 401 of crossbeam 4 respectively, and cutting head motion assembly 3 effectively is supported on also can be along the guide rail smooth sliding on the crossbeam 4.Servo drive motor 101, reduction box 102 and gear 112 are linked in sequence, and vertically install on the top boards 104 by support 111, and the reduction box installing hole on the support 111 is an eccentric orfice, therefore can tooth bar 402 precisions on gear 112 and the crossbeam 4 be meshed by adjusting.Header board 103 is equipped with upper encloser 110 and lower encioser 113 up and down.
