Description
Technical field
The present invention relates to steel pipe process equipment field, especially steel pipe intersection line cutting machine.
Background technology
Need the multiple tracks pipeline to pass through connection mutually in the complicated pipelines; The intersection of steel pipe cutting at present is basically by after the artificial setting-out; Carry out the cutting of flame gun or plasma gun by hand, the disadvantage of this hand cut is that cutting accuracy is difficult to guarantee that cut surface is coarse; And labour intensity is big, and production efficiency is extremely low.Existing steel pipe intersection line cutting machine can high-efficiency high-quality the cutting of completion steel-tube intersection-line; But its mobile platform that flame or plasma cutting gun are installed directly moves on the base track of cutting machine; Its jib-length is longer, cause rigidity a little less than, influence positioning accuracy.
Summary of the invention
The applicant directly moves at the base track to the intersection-line cutting machine mobile platform of above-mentioned existing steel pipe; The more weak shortcomings such as precision that influence of rigidity; A kind of rational in infrastructure, cutting head of triaxial steel pipe intersecting wire cutting machine longitudinal moving mechanism that rigidity is stronger is provided, can improves positioning accuracy and cut quality greatly.
The technical scheme that the present invention adopted is following:
A kind of cutting head of triaxial steel pipe intersecting wire cutting machine longitudinal moving mechanism; Said cutting machine one end is provided with main spindle box; Main spindle box connects rotating chuck, and the foundation of incision machine track is provided with some steel pipe bracing frames, on base top, be positioned at the height of rotating chuck; Be parallel to the base track and be provided with crossbeam; On base, cutting head motion assembly is arranged on through slide device on the guide rail of crossbeam said crossbeam through stent support, realizes dynamic and electrical connections through pipeline and power section and control section.It is further characterized in that:
The header board of said slide device is hooked on the guide rail of said crossbeam through the right-angle connecting plate of rear side top and the bottom; Offer some installing holes on the straight horizontal edged surface of said right-angle connecting plate; Outside installing hole installs and fixes axle; Installed inside hole setting-up eccentricity axle is installed horizontal bearing on said fixed axis and the eccentric shaft; Straight horizontal edged surface internal holes dress transverse axis, said transverse axis is installed vertical capacity eccentric bearing; Laterally the outer collar of bearing and vertical bearing contacts with last bottom surface with the side of the guide rail of crossbeam respectively; Be fixed with the motor, reduction box and the gear that are linked in sequence on the connecting plate, the tooth bar engagement on said gear and the crossbeam.
Cutting head of triaxial steel pipe intersecting wire cutting machine longitudinal moving mechanism of the present invention adopts CNC to carry out numerical control control, can carry out the high accuracy cutting of intersection to the pipe material of different tube diameters, different length, on the guide rail that is arranged on crossbeam with cutting head motion assembly slip; Easy to adjust; Guiding is accurate, and servomotor can accurately be realized feeding with the rack-and-pinion engagement, avoided that existing mobile platform jib-length is long, a little less than the rigidity, influence the defective of positioning accuracy; Rigidity is better, and precision is higher.
