(3) on a platform to triangle tube sheet and guide plate, position weldering between triangle tube sheet and the set square, wherein first weld seam, second weld seam are downhand welding, the 3rd weld seam, the 4th weld seam are horizontal position welding;
(4) frame is hung on positioner, make the 3rd weld seam of frame and the 4th weld seam go to the downhand position, grind off the tack welding of former horizontal position welding weld seam, position weldering again;
(5) the 3rd weld seam and the 4th weld seam are carried out backing welding;
(6) rotary frame carries out backing welding to first weld seam and second weld seam,
(7) rotary frame carries out the moulding weldering to the 3rd weld seam and the 4th weld seam;
(8) rotary frame carries out the moulding weldering to first weld seam and second weld seam;
(9) utilize the ultrasonic magnetic powder inspection technology butt welded seam that involves to carry out quality inspection.
When the diabolo screw sleeve type machine frame welded, CO was adopted in described welding
2Laser welds dolly automatically to carry out.
Technique effect of the present invention is:
(1) because the present invention adopts the machining mode to prepare the triangle tube sheet, make the assembling of triangle tube sheet and guide plate and set square can accomplish the zero clearance, and adopt under the condition that illumination method detects, to positioning weldering between triangle tube sheet and guide plate and the set square, guaranteed the assembling zero clearance, realized that welding is impermeable, triangle panel weld backside cleaning;
(2) downhand welding is all adopted in all weld seam tack weldings and welding, and the fusion penetration of welding is secure, and all adopts the welding of just finishing weld seam through tack welding, backing welding and moulding weldering.Adopt CO
2Automatically the weldering dolly carries out the downhand welding welding. and the result of check shows that weldquality is good, does not produce distortion.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing, but should therefore not limit protection scope of the present invention.
See also Fig. 2, Fig. 3 and Fig. 4, triangle screw sleeve type machine frame of the present invention is symmetrical fully about being, so the two-part welding manner in the left and right sides is identical, during embodiment below introduced, we were that example describes in detail with the right half part.The step of the welding method of triangle screw sleeve type machine frame of the present invention is as follows:
(1), adopt machining process to prepare triangle tube sheet 3 according to the structural design of triangle screw sleeve type machine frame;
(2) the first triangle tube sheet 31 and the second triangle tube sheet 32 are placed first guide plate 21 of triangle screw sleeve type machine frame and the right angle part that first set square 41 intersects, form the right angled triangle sleeve pipe, adopt the irradiation mode to detect, guarantee that the first triangle tube sheet 31 becomes the zero clearance when assembling with first set square 41 with first guide plate 21 with the second triangle tube sheet 32;
(3) on a platform to the first triangle tube sheet 31 and the second triangle tube sheet 32 and first guide plate 21, position weldering between the first triangle tube sheet 31 and the second triangle tube sheet 32 and first set square 41, wherein first weld seam 51, second weld seam 52 are downhand welding, and the 3rd weld seam 53, the 4th weld seam 54 are horizontal position welding;
