Detailed description of the invention
For making the utility model clearly be understood, below in conjunction with specific embodiment, the utility model is described in further detail.But this should be interpreted as and be only limitted to following embodiment to the scope of the above-mentioned theme of the utility model, all technology realized based on the utility model content all belong to scope of the present utility model.
A specific embodiment of the present utility model is the weld bond Anti-deformation tooling with the research and development of products for Fig. 1-2, to improve the precision in this product quality and collar extension gap.
As in Figure 3-5, be the body schematic diagram of the utility model one specific embodiment.And referring to Fig. 6-7, it is the chuck increased for the product be similar to shown in Fig. 1-2.
Special weld bond Anti-deformation tooling in this specific embodiment, fixed with chuck 60 by 120 ° by three cylindrical bodies 20 had for the active section of fixing gap size, 13 li, collar extension gap is seated in during use, wherein the support arc surface R of the active section 21 of cylindrical body 20 be processed into one heart, the cylinder of diameter not etc. (be advisable for general 4 groups, diameter is R1>R2>R3>R4 in the present embodiment).
Wherein, between adjacent support arc surface R, vertical plane, inclined-plane or curved surface can be adopted to be connected.
In the present embodiment, be a kind of preferred version of employing 3 cylindrical bodies, when it can avoid any two lines by chuck hub line, the situation of the power appearance superposition that workpiece expands or contraction produces can be made.
And this chuck 60 preferably has the extension pawl of more than 3 or 3, described extension pawl with chuck hub be radioactivity isogonism distribution, and described accommodating hole 61 be located at extend pawl deviate from chuck hub one end.
Preferably, this accommodating hole 61 is the elongated hole extended along diameter of chuck, to adapt to different nozzle diameters.
In this enforcement, be that bottoming is welded by spot welding assembling, the amount of contraction of secondary welding and the conventional size of current of welding determines the diameter of four groups of different cylinders (slightly larger than actual needs size, as shown in Figure 4) respectively.
