Description
Technical Field
The utility model belongs to the technical field of stud welding auxiliary machinery, a novel stud welding back supports frock is related to.
Background
Stud welding is a fusion welding method for welding a stud welding nail to a base metal by forming a loop by a welding gun and a grounding wire, and is widely applied to industries such as automobiles and the like; because there is a downward impact force during welding, especially for thin plates, the back of the welding position of the base material needs to be supported by a supporting cushion block, otherwise welding defects are easily generated.
With the development of the weight reduction trend of automobiles, the stud welding application of the thin plate is more and more extensive. The existing thin plate stud welding technology mostly uses a method for clamping the edge of a workpiece by a ground wire, and the method has the conditions that the phenomenon of magnetic blow is more, the effect of on-duty experimental parameters on the workpiece is not as expected, and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the problem that the stability of the joint strength is not good enough after the stud welding test parameters are used in the actual production due to the large thickness of the supporting cushion block and the rapid heat dissipation of the thin plate stud welding; the phenomenon of magnetic blow of stud welding is solved to a certain extent; a pillow block can only meet the problem of one height. Provides a novel stud welding back supporting tool,
the purpose of the utility model can be realized by the following technical scheme: the support column is a semi-separated platform, and the platform is used for supporting base materials at a stud welding position of a workpiece; the base is divided into a cylindrical portion and a fixing portion, the diameter of the supporting column is smaller than the inner diameter of the cylindrical portion, the supporting column is movably fixed in the cylindrical portion, positioning holes are formed in the fixing portion, bolt holes are symmetrically formed in the cylindrical portion, and a tightening bolt is screwed into the bolt holes to adjust the height of the supporting column.
Further, the platform is 20mm thick.
Further, the cylindrical portion and the fixing portion are of an integrally molded structure.
Furthermore, the supporting tool is made of a conductive material and can form a loop with a stud welding gun.
The utility model has the advantages that:
the utility model discloses a control welding return circuit solves the problem that produces magnetic blow-off easily, solves the problem that experimental parameter can't reach expected effect in actual production through control welding heat dissipation degree on a perpendicular line.
The utility model discloses a stud welding back supports frock can height-adjusting, satisfies the operating mode of co-altitude demand, need not whole change frock.
Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic view of the split structure of the present invention;
fig. 2 is a schematic view of the overall structure of the present invention;
fig. 3 is a schematic view of the tool of the present invention.
Detailed Description
A novel stud welding back supporting tool comprises a supporting column 1, a base 2 and a tightening bolt 3, as shown in figures 1, 2 and 3, wherein the supporting column 1 is a semi-separated platform, and the platform is used for supporting a base material of a stud welding position of a workpiece; the base 2 is divided into a cylindrical portion 21 and a fixing portion 22, the diameter of the support column 1 is smaller than the inner diameter of the cylindrical portion 21, the support column 1 is movably fixed in the cylindrical portion 21, the fixing portion 22 is provided with positioning holes 23, bolt holes 24 are symmetrically formed in the cylindrical portion 21, the tightening bolts 3 are screwed into the bolt holes 24, and the height of the support column 1 is adjusted.
The cylindrical portion 21 and the fixing portion 22 are integrally formed.
The supporting tool is made of a conductive material and can form a loop with a stud welding gun.
The support column is a platform with the upper part of the main body being semi-separated, the thickness of the platform is 20mm, and the platform is used for supporting a base material 25 of a stud welding position of a workpiece.
Base: the fixing device is mainly used for fixing the supporting column. Meanwhile, a positioning hole is formed in the base and used for installing the tool on the whole workpiece tool.
And (3) tightening the bolt: and screwing the tightening bolt into the cylindrical part of the base to fix the height of the support column.
When in use, the utility model discloses there is the platform of a half separation with the part of mother metal contact, and platform thickness is 20 mm. The main part of this frock can height-adjusting, carries out the top by the bolt after the regulation tightly.
The fixing part of the base is provided with the positioning hole, so that the base can be placed on different overall tools, the production requirement is met, and the overall replacement is not needed; FIG. 1 a stud weld 26;
the foregoing is merely exemplary and illustrative of the structure of the invention, and various modifications, additions and substitutions as described in the detailed description may be made by those skilled in the art without departing from the structure or exceeding the scope of the invention as defined in the claims.
Claims (4)
