Description
Technical Field
The invention relates to welding auxiliary equipment, in particular to a spot welding tool for a top plate of a gas water heater mask.
Background
The mask and the mask top plate are important parts forming a shell of the gas water heater, the mask and the mask top plate are formed by punching and bending thin steel plates, the mask is provided with a rear wall, a left side wall and a right side wall and is U-shaped, the lower edges of the rear wall and the left side wall and the right side wall of the mask are provided with folded edges folded inwards, the mask top plate is in a thin plate shape, the middle part of the mask top plate is provided with a trapezoidal notch, and the mask top plate is placed in the mask during welding and is placed on the folded edges of the mask for placing and welding. The existing spot welding tool is clamped front and back, the mask top plate is easy to deform due to the fact that a sheet metal part is thin and the clamping force is slightly large, and the side face is not provided with a clamping function and needs to be supported by another person, so that time is wasted, and labor cost is increased.
How to design a section can realize independently accomplishing alone and simple operation's spot welding frock to gas heater face guard roof specially, is the technical problem that technical personnel in the field need solve.
Disclosure of Invention
The invention aims to solve the technical problem of providing a spot welding tool special for a gas water heater mask top plate, which can be independently completed by one person and enables two components to be tightly combined, aiming at the current situation of the prior art, and by adopting the tool, the welding working time can be shortened, the production efficiency can be improved, the labor cost can be reduced, and the mask top plate can not be deformed.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a gas heater face guard roof spot welding frock, includes table surface, its characterized in that: the spot welding base plate is fixed on the working table surface and used for placing the mask and the mask top plate; a plurality of rear limiting columns which are arranged at left and right intervals are fixed on the working table and vertically extend upwards to limit the rear wall of the mask; a plurality of left limiting columns which are arranged at intervals in the front-back direction are fixed on the spot welding base plate and vertically extend upwards to limit the left side wall of the mask; the middle limiting block is fixed on the spot welding substrate and is embedded into a gap in the middle of the mask top plate so as to position the mask top plate; the lower pressure rod is driven by a lower pressure elbow clamp arranged on the working table surface to deflect and press down, and the deflection and pressing down of the lower pressure rod can press the top plate of the mask downwards so as to tightly combine the top plate of the mask with the flanging at the bottom of the mask; and the side pressure rod is arranged on the working table surface and positioned at the right side of the spot welding substrate, is driven by a side elbow pushing clamp arranged on the working table surface to move left and right, and moves laterally to press the lower part of the right side wall of the mask so as to tightly press the right side wall of the mask and the side wall of the mask top plate.
The back of the middle limit block is provided with a notch, the notch is internally provided with a push block which is supported by a spring and keeps the backward movement trend, and the push block is contacted with the back wall of the gap of the top plate of the face mask, so that the backward movement of the push block can push the top plate of the face mask to move backward, and the backward flanging of the top plate of the face mask is tightly pressed with the inner surface of the back wall of the face mask. Through the promotion of ejector pad, can promote the backward movement of face guard roof, ensure that the back turn-ups of face guard roof and the back wall internal surface of face guard combine more closely, guarantee that welding position is accurate between face guard roof and the face guard.
Alternatively, the rear limiting columns are three because the length of the mask is larger than the width of the mask. The left limit columns are two.
Because the length of the face mask is longer, two lower elbow pressing clamps are arranged and are respectively positioned at the left side and the right side of the middle limiting block.
As the selection, above-mentioned elbow clamp pushes down includes holder, arm lock, linking arm and actuating arm, the holder is fixed on table surface, the lower extreme at the rear portion of arm lock and the lower extreme of linking arm all articulate on the holder and around the interval set up, the upper end at the rear portion of arm lock and the upper end of linking arm then articulate in the front portion of actuating arm, push down the pole and install the anterior and perpendicular to arm lock at the arm lock. The driving arm can keep the movable pressing rod in a pressing state after passing through a dead point.
For making the front and back position of depression bar adjustable, it has the bar hole to open on the above-mentioned arm lock, the depression bar is worn to establish in the bar hole and through threaded connection at the last nut and the lower nut lock on the arm lock of depression bar down.
Alternatively, the side elbow-pushing clamp comprises a side clamping seat, a side connecting arm and a side driving arm, wherein the side pressing rod is restrained at the left part of the side clamping seat and can only slide left and right, the front end of the side connecting arm is hinged with the rear end of the side pressing rod, the rear end of the side connecting arm is hinged with the peripheral wall of the side driving arm, and the lower end of the side driving arm is hinged with the right part of the side clamping seat. The side driving arm can keep the movable side pressure rod in a pressing state after passing through a dead point.
Compared with the prior art, the invention has the advantages that: the mask is placed on a spot welding base plate firstly, the left limiting column and the rear limiting column limit the left side and the rear side of the mask simultaneously, then a mask top plate is placed into the mask and placed on the spot welding base plate, the mask top plate is provided with a limiting function by the middle limiting block, the mask top plate can be tightly attached to the back of the mask, then the mask top plate and the mask are tightly attached to the left and the right by the pushing of the side pressure rod through the side pressure elbow clamp action, then the lower pressure rod is downwards pressed by the lower pressure elbow clamp action, the mask top plate is tightly combined with the flanging of the bottom of the mask, and finally spot welding processing is completed. Spacing mode in the middle of this frock adopts, make it can be more easy exact location, the skew has been avoided, it is tight to adopt down to press the elbow to press from both sides simultaneously, it is zero to make two work piece combination regional clearances, the welding is accurate, use the side pressure elbow at last to press from both sides, reduce the work load of other alone, make alone just can operate, and the locate mode is the manual drive mode, the advantage with low costs has, because of pushing down the depression bar and being located the face guard, the inconvenient cylinder that arranges, the event is unsuitable to adopt the mode of cylinder to compress tightly, this frock adopts the mode that the elbow pressed from both sides to compress tightly, do benefit to the overall arrangement.
