Abstract
The invention relates to coaxial automatic welding technology for a large-scale mechanical member through laser fine adjustment. The technology comprises the following steps: a long trunnion section, a short trunnion section of a welding assembly backing ring and two sector sections. In welding, according to the dimension of a large-scale backing ring structure, a ground line transect is lined in a welding platform. After welding assembly, the two trunnion sections are put on the welding platform according to design requirement. A water level arranged in the middle part of trunnion blocks of two sides, a frame water level arranged on two trunnions respectively and a wire hanging hammer arranged at two shaft ends of each trunnion are adopted to align the centers of two shaft ends of the trunnion of each trunnion block so that four centers of two trunnions are concentric; and simultaneously, the process control distance between the end faces of the outer shafts of two trunnions on two trunnion blocks is adjusted. A laser alignment method is adopted for fine adjustment so as to adjust coaxiality of two trunnions; after accurate adjustment, two trunnion sections and the welding platform are fixed; the upper ends and the lower ends of the two trunnions are provided with the fan-shaped sections respectively and align to form the backing ring; two trunnion sections are adjusted to set positions and are fixed with the welding platform respectively. An automatic welding machine is used to weld, or a plurality of persons weld and fill a weld joint simultaneously to complete the welding of the large-scale backing ring. As the technology adopts laser quasi direct current adjustment, the two trunnions of the backing ring have high coaxiality and welding precision, and are convenient to adjust so as to reduce production cost.
Description
Technical field
The present invention relates to a kind of large-sized mechanical component, is the integrated solder technology of axiality of mammoth conveter backing ring two gudgeons specifically.
Background technology
Backing ring is one of key equipment of automation pneumatic steelmaking, is the main member that bears converter body, so the control of the axiality of welding workmanship, the especially ring trunnion of backing ring, will directly influence the result of use and the life-span of converter.
Adopt present machine-tooled method, the axiality of gudgeon is difficult to reach required precision, thereby influences the converter total quality.
Summary of the invention
Purpose of the present invention provides a kind of integrated solder technology of trunnion of converter axiality, has improved the axiality between backing ring two gudgeons, thereby improves the mammoth conveter quality.
The technical scheme that adopts is:
Laser delicate-adjustment large-sized mechanical component coaxial automatic welding technique, its step comprises:
1, dress weldering backing ring screech owl shaft part, cropped ear shaft part and two fan-shaped section.
2, when welding, earlier according to large-scale backing ring physical dimension on jig, draw line-transect.
3, the two gudgeon sections that dress welded are placed on the jig by designing requirement.Employing be located at spirit level in the middle of the gudgeon piece position, both sides, respectively be located at frame type level meter on two gudgeons, be located at the ceiling hammer of each gudgeon two axial ends respectively, the two axial ends center of gudgeon on each gudgeon piece of centering, make four hearts of two gudgeons concentric, the technology controlling and process spacing of aligning two gudgeon outer shaft end faces on the gudgeon piece of both sides simultaneously.
Adopt the method for laser alignment accurate adjustment, adjust two gudgeon axialities, after the adjustment accurately, two gudgeon sections and jig are fixed, after two gudgeon upper and lower ends are loaded onto fan-shaped section respectively, are aligned to a backing ring, adjust to desired location, fix with jig respectively.
4, adopt the automatic welding machine welding, or many people, welding simultaneously, the filling weld seam is finished large-scale backing ring welding.
Because the present invention adopts laser alignment stream to adjust, backing ring two gudgeon axialities, weldering is smart high, easy to adjust, has reduced production cost.
Description of drawings
Fig. 1 is the welding process schematic diagram of a kind of embodiment of the present invention.
The specific embodiment
Laser delicate-adjustment large-sized mechanical component coaxial automatic welding technique comprises the steps:
1, on platform 1, presses the setting-out by drawing of backing ring size.
2, assembling welding good two on 2,3 and two fan- shaped section 4,5 of gudgeon section be placed on the jig by design attitude, adjust gudgeon section and fan-shaped section, after coincideing with full pattern, determine fan-shaped section butt joint groove position, and finished edge.
3, adopt method of laser alignment to adjust two gudgeon axialities.
Adopt helium atmosphere laser instrument 6 to make light source, it sends the red beam of 6328 dusts, intuitive is good, good directionality promptly has the intuitive of drawing the steel wire method, has the accuracy of optical alignment again, helium atmosphere laser instrument 6 is arranged on cropped ear shaft part 2 one sides, and aim at the axis hole of gudgeon section 2, between gudgeon section 2 and gudgeon section 3, transmitter-telescope 7 is set, at the graticulated long rectangular wave strap 8 of gudgeon section 3 arranged outside.Photelectric receiver 9 is set outside zone plate 8, to gudgeon section and fan-shaped section accurate adjustment, adjust two gudgeons coaxial after, spot welding location.
4, many people, the welding of filling simultaneously.
5, behind the axis hole of red beam through gudgeon section 2 that helium atmosphere laser instrument 6 sends, again through the transmitter-telescope emission, pass the axis hole of gudgeon section 3 and the cross bar seam back of zone plate and received by photelectric receiver 9, carry out accurate adjustment, it is coaxial to reach two gudgeon sections.
