Description
Technical field
The present invention relates to the welding tooling field, specifically a kind of energy storage spot welding positioning device for the plate honeycomb.
Background technology
In the fluid machinery of High Rotation Speed, in order to raise the efficiency, to reduce and leak, keep the operating pressure of each chamber, usually need to adopt the various measures of obturaging, the sealing of comb tooth coating and honeycomb seal are in contactless dynamic seal (packing) most widely used two kinds.Honeycomb seal not only sealing characteristics is good, also has good dynamics, along with the processing of honeycomb core lattice and updating of welding procedure, adopt the cost of honeycomb seal technology just constantly to reduce, honeycomb seal is just being obtained in the high-efficiency high-power fluid machinery more and more widely and is being used.Honeycomb is the structural member of the similar honeycomb made by many materials as thin as a wafer, and the general honeycomb parts of obturaging are with the method for one or more layers honeycomb with vacuum brazing, are welded on the inside and outside surface or arc plate of annular work piece.Before vacuum brazing, honeycomb need to be positioned on arc plate or ring-type frock, usually adopt the localization method of energy storage spot welding.
Be to guarantee the assembling of plate honeycomb in subsequent components, require honeycomb to be ± 0.15mm apart from the location dimension tolerance at plate edge.Honeycomb is that the core lattice that the thin slice of thickness 0.05mm surrounds are spliced, its for elastic construction and the strip width dimensional tolerance made larger, if honeycomb is apart from plate size strict guarantee on one side, but because honeycomb width dimensions tolerance is large, also can cause honeycomb according to plate another side dimension overproof, if the insecure or operate miss in outermost layer honeycomb thin slice location very likely causes the postwelding cell edge overproof according to the location dimension of plate, cause subsequent parts assembling difficulty.
The vacuum brazing technique patent of the honeycomb class part that can inquire both at home and abroad at present is all the soldering processes that machine adds annular honeycomb parts, the annular honeycomb is assembled by ring body cylindrical or bottom surface when soldering, there is not the problem of using energy storage spot welding positioning tool, but the assembling and positioning of plate honeycomb need to guarantee the back gauge size of honeycomb on the plate face, through domestic and international patent consulting, do not inquire the patent of invention of plate cellular localization device.
Summary of the invention
For overcome exist in prior art easily cause the postwelding cell edge overproof according to the location dimension of plate, make the deficiency of subsequent parts assembling difficulty, the present invention proposes a kind of for plate honeycomb energy storage spot welding positioning device.
The present invention includes base, 2 pressing plates, guide rod, spring and 2 dividing plates; Wherein 2 pressing plates are placed on the erecting bed of base and lay respectively at the both sides of this erecting bed; 2 dividing plates are placed in the positioning table upper surface of base, and lay respectively at the both sides of described boss surface; Dividing plate is connected with adjacent pressing plate respectively; Guide rod is packed into is positioned at guide rod via hole on base and pressing plate, and by dog screw, this guide rod is held out against, and prevents that this guide rod from rotating; 2 springs are set in the two ends of guide rod, and this spring is laid respectively in the guide rod via hole; By nut, guide rod is tightened up.
The upper surface of described positioning table and erecting bed is cancave cambered surface, and the radius of positioning table cancave cambered surface is identical with the radius of institute locating element; On the cancave cambered surface of positioning table, the plate mounting groove is arranged; The bottom land surface of this plate mounting groove is also cancave cambered surface, and the degree of depth of plate mounting groove is identical with the thickness of plate.
Described guide rod via hole is at the center of base and connect the base boss width; Aperture in the middle part of this guide rod via hole is identical with the external diameter of guide rod, and guide rod is coordinated with guide rod via hole gap; The aperture at the two ends of described guide rod via hole is slightly larger than guide rod external diameter and ring spring external diameter sum.
Described dog screw is positioned at the end face at base two ends, and the position of the installing hole of this dog screw is corresponding with the guide rod via hole; The center line of the vertical and guide rod via hole of the center line of the installing hole of dog screw.
The guide rod via hole is also arranged on described pressing plate; This guide rod via hole is concentric with the guide rod via hole on the base central boss; This guide rod via hole is positioned at the aperture maximum of base central boss side surface one end, and this aperture is slightly larger than guide rod external diameter and ring spring external diameter sum.
When utilizing the present invention to spot weld the honeycomb energy storage on plate, in three contact resistances of contact resistance between contact resistance between the contact resistance of electrode and honeycomb, honeycomb and plate, plate and bottom electrode, contact resistance between honeycomb and plate is useful resistance, and useful resistance is converted into resistance heat with welding current.All the other resistance are harmful resistance, and the contact resistance between plate and bottom electrode can produce spark burn plate; The contact resistance of top electrode and honeycomb can the serious burn honeycomb cause part to scrap.The lower bottom base of energy storage spot welding positioning tool of the present invention is the red copper material, and the harmful resistance when farthest having reduced energy storage spot welding, top board are the insulated nylon piece, wound the honeycomb sidewall in the time of can preventing energy storage spot welding.Use energy storage spot welding positioning tool of the present invention, can effectively guarantee the location dimension of honeycomb on plate, and due to the use of positioning tool, prevented wounding of part, guaranteed the energy storage spot welding alignment quality of part.
The present invention has guaranteed the location dimension of part, increases work efficiency, and obtains obvious economic benefit.Simultaneously, the present invention is applicable to the fields such as naval vessel, gas turbine, the economic benefit that can produce and social benefit.
