Description
Technical field
The present invention relates to the processing tool field of dividing plate class hollow stationary blade blade, be specially the grip device for hollow stationary blade turnover vapour limit spot welding operation.
Background technology
Hollow shelf class stator blade blade is welded into after welding punching press by inner arc plate with back of the body arc plate, in order to ensure that weld size improves welding quality, carry out inner arc plate and back of the body arc plate enter lagging edge integral solder before, first spot welding process is carried out to welding region, utilize spot welding to link together interior, back of the body arc plate.The welding position, turnover vapour limit of hollow stationary blade is in the past placed directly in together, by hand adaptation spot welding.Be subject to the impact of the own profile dimensional tolerance of inner arc plate and back of the body arc plate, adopt the spot welding of hand adaptation, the uniformity of weld width cannot ensure, often need repeatedly repair spot welding guarantee weld width again, have a strong impact on working (machining) efficiency, and the tolerance of groove angle is also uncontrollable within the scope of ± 5 °, can have influence on the solder yield of blade.
Summary of the invention
For the problems referred to above, the invention provides the grip device for hollow stationary blade turnover vapour limit spot welding operation, it can solve the problem of the weld width lack of homogeneity that existing hand adaptation spot welding exists, and can ensure that the angle of bevel for welding meets margin of tolerance requirement, improve blade solder yield and improve working (machining) efficiency.
Its technical scheme is such, it is characterized in that: it comprises upper plate and lower shoe, the bottom surface of described upper plate is fixed with compression module, the upper surface of described lower shoe is fixed with profile locating module, the arranged on left and right sides end of described profile locating module is separately installed with locating piece and axial location block, is led, compressed close up by forcing press between described upper plate and lower shoe by positioning guide column.
It is further characterized in that: described profile locating module surface is mated with the convex profile of blade to be processed, and described compression module surface is mated with the interior arc shaped surface of blade to be processed; It also comprises blade type lumen-supporting devices, during use, described blade type lumen-supporting devices is filled between the inner arc plate of spot welding blade to be processed and behind arc plate, described blade type lumen-supporting devices is combined by multiple cavities bear block, and in the combination outer mold surface of described multiple cavities bear block and the blade of processing to be welded, profile is agreed with; The end, connection composition surface of cavities bear block described in each is provided with draw-in groove and joint, is connected in described multiple cavities bear block, between adjacent two cavities bear blocks by described draw-in groove with joint split.
Adopt the grip device for hollow stationary blade turnover vapour limit spot welding operation of the present invention, its beneficial effect is: it is by forcing press, by the compression module of upper plate and the profile locating module of lower shoe by the inner arc plate of hollow stationary blade, the location clamping of back of the body arc plate, simultaneously, blade transverse ends is located by locating piece and axial location block, it locates reliable clamping, ensure that the stability of blade during spot welding operation, thus effectively can ensure that the uniformity of weld width and groove angle allowance control are within the scope of ± 5 °, decrease the repair time of spot welding operation, improve working (machining) efficiency, simultaneously, blade type lumen-supporting devices is filled with in die cavity between inner arc plate and back of the body arc plate, it effectively supports the inner arc plate of hollow stationary blade and back of the body arc plate when spot welding, avoid the welding deformation that spot welding operation produces blade profile, further ensure the uniformity of weld width and groove angle allowance control within the scope of ± 5 °, thus for ensureing that blade integral welding quality lays the foundation.
