Abstract
The invention relates to a weave welding method of a mixed flow generator key bar, belonging to the technical field of hydraulic generator. The weave welding method of a mixed flow generator key bar is characterized in that a key bar and a supporting block are clamped by a clamping cap when the generator key bar is subjected to weave welding and are put on the annular plate of an engine base to adjust the internal diameter size and a chord tool; the key bar and the supporting block are in spot welding to firmly connect the annular plate and the supporting block; after the key bar is naturally cooled, the internal diameter size and the chord tool of the key bar are measured; if the internal diameter size and the chord tool reach the design requirement by measuring, the weave welding of the key bar of the generator is finished, otherwise, the key bar is adjusted to reach the design requirement. The invention has the advantages of simple technology, convenient operation, time and labor saving, low labor intensity, high weave welding precision, high production efficiency and the like and is economical and practical.
Description
Technical field
The invention belongs to technical field of hydraulic generators, particularly relate to a kind of weave welding method of mixed flow generator key bar.
Background technology
At present, the pendulum of mixed flow unit positioning bar weldering needs the time long, and speed is slow, and method for a long time is: the some holder is fast, and the positioning bar pendulum is looked for a level on the ring flat-plate of out frame, after positioning bar and tray point is firm, positioning bar is fallen the leg on the full weld tray.Positioning bar behind the full weld has produced very big distortion, itself and tray need be adjusted to 90 degree levels, get back on the position of former ring flat-plate, can not be gapped between tray and ring flat-plate, otherwise should continue to adjust to suitable till, produce huge distortion so that reduce tray and ring flat-plate welding back, brought quality problems for the positioning bar internal diameter chord tool of pendulum postwelding.
Summary of the invention
The present invention provides a kind of weave welding method of mixed flow generator key bar for solving the technical problem that exists in the known technology.
The purpose of this invention is to provide a kind of weave welding method of mixed flow generator key bar with characteristics such as technology is simple, easy to operate, economical and practical, time saving and energy saving, labour intensity is low, production efficiency height.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of weave welding method of mixed flow generator key bar, be characterized in: during the weldering of generator positioning bar pendulum, earlier positioning bar and tray are blocked with the card cap, pendulum is adjusted internal diameter size chord tool on the ring flat-plate of support; Spot welding positioning bar tray is firm with ring flat-plate and tray point then; The internal diameter size chord tool of measurement and positioning muscle behind the natural cooling, measurement reaches designing requirement, finishes the weldering of generator positioning bar pendulum; When measurement does not reach designing requirement, adjust positioning bar and reach designing requirement.
The present invention can also adopt following technical scheme: described weave welding method of mixed flow generator key bar is characterized in: during the weldering of generator positioning bar pendulum frame level is set on positioning bar and carries out leveling.
Advantage and good effect that the present invention has are: weave welding method of mixed flow generator key bar is owing to adopted brand-new technology scheme of the present invention, the present invention compares with prior art has following characteristics: save time: the former method that falls full weld after needing positioning bar water detection flat is removed, directly spot welding on ring flat-plate, need 15-20 days time with positioning bar of forward swing weldering, only needed to finish now in 10-15 days, and shortened the final assembly time greatly.
Laborsaving: former tray and positioning bar fall the full weld leveling after having looked for level, again positioning bar pendulum on ring flat-plate, as gapped between tray and the ring flat-plate, also need transfer tray till very close to each other repeatedly, strengthened labour intensity, operating rate is slow.
Reach designing requirement: since positioning bar and tray directly on ring flat-plate spot welding and full weld reduced distortion, basically internal diameter size chord tool can not occur because tray and ring flat-plate by the gap, problems such as the thick distortion of spot welding have reached designing requirement.
This innovative approach has obtained application in practice, has obtained certain effect, not only saves time but also laborsaving, improves and comes operating efficiency, has shortened the work period simultaneously, and that guarantees both quality and quantity has finished designing requirement, for the assembling of large-scale unit is laid a good foundation.
The present invention has that technology is simple, easy to operate, economical and practical, time saving and energy saving, labour intensity is low, pendulum weldering precision height and production efficiency advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1-positioning bar, 2-ring flat-plate, 3-tray, 4-frame level.
Embodiment
For further understanding technology contents of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows: consult accompanying drawing 1.
1 one kinds of weave welding method of mixed flow generator key bar of embodiment during the weldering of positioning bar pendulum, block positioning bar 1 and tray 3 usefulness card caps earlier, and pendulum is adjusted internal diameter size chord tool on the ring flat-plate 2 of support; Spot welding positioning bar tray then is with ring flat-plate 2 and 3 jails of tray; The internal diameter size chord tool of measurement and positioning muscle behind the natural cooling, measurement reaches designing requirement, finishes the weldering of generator positioning bar pendulum; When measurement does not reach designing requirement, adjust positioning bar and reach designing requirement.During the weldering of generator positioning bar pendulum frame level 4 is set on positioning bar and carries out leveling.
Reality of the present invention is specifically put the weldering process: weave welding method of mixed flow generator key bar is that original technology has been done bold improvement, great amount of manpower and time have been saved, alleviated a large amount of working strengths, positioning bar pendulum weldering has just reached and has once put muscle, and secondary is repaiied the new method of muscle.
During concrete enforcement, positioning bar and tray is good with card cap card, and pendulum finds internal diameter size chord tool on the ring flat-plate of support.Relevant size is transferred to the designing requirement scope, then point location muscle tray and ring flat-plate and tray point jail.Whether the internal diameter size chord tool of measurement and positioning muscle reaches designing requirement behind the natural cooling, otherwise, repair positioning bar to reach designing requirement.
Claims (2)
1. a weave welding method of mixed flow generator key bar is characterized in that: during the weldering of mixed flow generator positioning bar pendulum, earlier positioning bar and tray are blocked with the card cap, put on the ring flat-plate of support, adjust internal diameter size chord tool; The spot welding tray is firm with ring flat-plate and tray point then; The internal diameter size chord tool of measurement and positioning muscle behind the natural cooling, measurement reaches designing requirement, finishes the weldering of mixed flow generator positioning bar pendulum; When measurement does not reach designing requirement, adjust positioning bar and reach designing requirement.
