Description
Technical field
The utility model relates to apparatus for welding and positioning technical field, more particularly, relates to a kind of spot welding location water heater liner welding tooling.
Background technology
Water heater liner is the device for storage of water in water heater, it must meet insulation, withstand voltage, non-corrosive, Non-scale, impermeable requirement, and stainless steel inner container is the important component part of water heater liner, its advantage is that inner bag material is good, intensity is high, high temperature resistant, anticorrosive, stable performance, not easily gets rusty.Because water heater liner is once damage is difficult to repair, its manufacturing process also seems quite important, but stainless steel inner container is difficult to welding, wherein maximum hidden danger is weld seam technique, in technological process, conventional solar boilers inner bag end cap welding method: inner bag cylindrical shell adopts artificial hand steered location, cannot ensure its positioning precision.The quality of welding is closely connected with the qualification of employee, mood, easily produces rosin joint phenomenon, and is not easily found, and just easily gets rusty and leaks, and cannot check before rosin joint part of factory between time slightly long weld seam.During current production water heater liner, be mostly pulling form moulding, produce upper shell and the lower shell of inner bag, then spot welding location, finally carries out gap welding, completes the assembling of water heater liner.
It is open that relevant technical matters has pertinent literature, as Chinese Patent Application No.: 201010548915.8, the applying date: on November 17th, 2010, this application case discloses a kind of end cover of water heater inner container automatic welding unit, comprise seam welder group, seam welder group comprises seam welder head, and seam welder head comprises float positioning device, seam welding electrode wheel and lowering or hoisting gear.Pass through such scheme, the end cap part of water heater liner can be held by float positioning device, coordinate lowering or hoisting gear, easily it can be docked with the shell portion of water heater liner, the cylindrical shell of water heater liner is by electrode wheel driven rotary, and the end cap of water heater liner and the welding edge of cylindrical shell are placed in stitch between welding electrode takes turns, carry out seam welder easily and do.Preferably, seam welder group upstream is also provided with spot welding unit, water heater liner is being transported into before seam welder group, first send into spot welding unit and carry out spot welding, and the end cap part of water heater liner is adsorbed by adsorption locating device, and provide rotary driving force by servomotor, spot welding work can be realized by soldering turret easily, and spot welding unit can weld at two ends simultaneously.The program is just fixed water heater liner at two ends, and locating effect is unsatisfactory, and can not ensure being uniformly distributed of spot welding anchor point, easily occurs that stress is concentrated and causes water heater liner deformation, affects product quality.
And for example Chinese Patent Application No. 201010281766.3, the applying date: on September 13rd, 2010, this application case discloses a kind of welding method of cylindrical shell of water heater, its main process is the stack shell of preparation one tubular, then the capping that root edge coordinates stack shell ora terminalis shape is prepared, capping is docked towards stack shell end with root edge, at the medial surface at stack shell ora terminalis place and capping root edge place, arrange one removably and put tool, the gap of corresponding capping and root edge, casting ditch is melted at the outer peripheral face putting tool recessed, finally weld along the joint of capping with stack shell ora terminalis, solder joint is made to fuse the root edge of capping, the ora terminalis of stack shell melting casts from and melts weldering ditch and form welding bead in.This welding manner still adopts traditional syllogic tube structure, cumbersome, and product easily leaks, and can not meet high-quality, efficient production requirement now.
