Abstract
The utility model relates to a spot welding bracing structure used on a spot welding machine. The spot welding bracing structure is characterized by comprising a panel contact, the panel contact can be movably mounted on a lower welding head of the spot welding machine in a covering mode and is composed of an upper panel part and a nut cap, the upper panel part is in contact with a workpiece, the nut cover is matched with the lower welding head, and the panel contact is machined and formed by red copper or zirconium chromium copper. Due to the fact that the panel contact is movably mounted on the lower welding head in a covering mode, the spot welding bracing structure used on the spot welding machine ensures that the direction of pressure borne by a workpiece is identical to the direction of an electric current on the condition that the workpiece is poor in flatness or is not horizontally arranged, thereby avoiding serious deformation of a welding spot and unfirm welding; in addition, due to the fact that an upper plane of the panel contact is larger than the lower welding head in area, heat suffered by the workpiece can be dispersed to a certain degree, surface deformation of the workpiece is reduced, and welding quality of the workpiece is improved.
Description
Technical field
The utility model relates to spot-welding equipment, particularly for the spot welding supporting construction on the mash welder.
Background technology
Mash welder is plate muscle class weld parts combination a kind of equipment commonly used.In actual spot welding operating process, the excessive and welding defective such as unreal of the distortion of solder joint is the processing of plate muscle class part, especially affects the key factor of quality in the steel office furniture production process take thin plate as main material.If it is excessive that the solder joint outer surface is out of shape, then must process with modes such as polishing, stifled putty, not only waste time and energy, also can affect electric conductivity and Electrostatic Absorption because increasing putty layer, make follow-up sprayed surface quality not good, therefore modern steel furniture surface solder joint must be " seamless " spot welding, and this just needs to improve welding equipment, makes that spot weld operation is simple and quality of welding spot stable.At present, the structural representation of common bench type spot-welder normal operating conditions as shown in Figure 3.Be specially: switch on after two workpiece are by upper soldering tip 2 and lower soldering tip 3 compactings, pressure point position moment of being heated is melted, after removing electric current and pressure, workpiece is cooled off rapidly, and merges mutually in condensation point and to be sticked together.In practical operation, or because helping workpiece, the operator can not guarantee abswolute level, or because of workpiece self injustice, or because adding the reasons such as rushing the flash support of cutting that occurs man-hour in the front, workpiece causes as shown in Figure 4 situation, workpiece is stressed to be passed through not on a line with electric current, the soldering tip binder is unreal, causes the solder joint distortion seriously or welds unreal.
Summary of the invention
The utility model provides a kind of for the spot welding supporting construction on the mash welder for solving the technical problem that exists in the known technology, this supporting construction is not subjected to workpiece self glacing flatness and workpiece to place uneven restriction, avoid the solder joint distortion serious unreal with welding, improved the welding quality of workpiece.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of for the spot welding supporting construction on the mash welder, it is characterized in that: comprise dull and stereotyped contact, described dull and stereotyped contact can be contained on the lower soldering tip of mash welder by removable cover, and it is made of the upper flat plate part that contacts with workpiece and the cap portion that cooperates with lower soldering tip; Described dull and stereotyped contact is by red copper or the machine-shaping of zirconium chromium-copper.
The technical scheme that the utility model can also be taked is:
Be the sphere fit structure between described block and the lower soldering tip, described block be provided with the ball-and-socket that matches with lower soldering tip.
Advantage and the good effect that the utlity model has are:
The utility model is contained in the dull and stereotyped contact of lower soldering tip by removable cover, guaranteed that workpiece pressure direction and the sense of current are consistent in the situation that workpiece self glacing flatness is poor or workpiece is placed injustice, thereby avoided the solder joint distortion serious unreal with welding; In addition, because the upper area of plane of planar contact is greater than lower soldering tip area, therefore discrete workpieces is heated to a certain extent, reduces the surface of the work distortion, improves the welding quality of workpiece.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state reference map of the present utility model.
Fig. 3 is the structural representation that existing mash welder is in normal operating conditions;
Fig. 4 is the structural representation that existing mash welder is in abnormal operating state.
Among the figure: 1, dull and stereotyped contact; 1-1, upper flat plate part; 1-2, cap portion; 2, upper soldering tip; 3, lower soldering tip.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1 and 2, be used for the spot welding supporting construction on the mash welder, comprise dull and stereotyped contact 1.Described dull and stereotyped contact can be contained on the lower soldering tip of mash welder by removable cover, and it is made of the upper flat plate part 1-1 that contacts with workpiece and the cap portion 1-2 that cooperates with lower soldering tip.Described dull and stereotyped contact is selected red copper or the machine-shaping of zirconium chromium-copper of steering capability excellence.Concrete, be contained in dull and stereotyped contacts cover on the lower soldering tip after, exert pressure away from the different position at middle part in the upper flat plate part, dull and stereotyped contact is along lower soldering tip beat certain angle, upper flat plate is horizontal by certain angle.
In the technique scheme: the contact-making surface of cap portion and lower soldering tip can adopt planar structure.From stability under loading, structure is installed compact angle and is considered.In the utility model, sphere fit structure more preferably between described block and the lower soldering tip, described block be provided with the ball-and-socket that matches with lower soldering tip.
Operation principle of the present utility model:
When the spot welding workpiece, dull and stereotyped contacts cover is contained on the lower soldering tip, then dull and stereotyped contact is placed on workpiece on the upper flat plate of dull and stereotyped contact between upper soldering tip 2 and lower soldering tip 3 at this moment.When workpiece was in the desirable level placement, the suffered pressure of workpiece was positioned on the vertical up and down the same line with electric current; When workpiece because of certain reason not during horizontal positioned, can resolve into the power with the power of the I direction of upper flat plate Surface Vertical and the F direction parallel with the upper flat plate surface when dull and stereotyped contact is stressed.Because bench type spot-welder upper arm and underarm can only move up and down, can not be displaced sideways, thereby M.E all is converted into the I directional pressure, because of dull and stereotyped contact good electric conductivity arranged again, therefore the pressure direction Main Function is on the sense of current, and namely pressure direction and the sense of current are consistent.The upper area of plane of planar contact is greater than lower soldering tip area in addition, and therefore discrete workpieces is heated to a certain extent, reduces the surface of the work distortion, improves the welding quality of workpiece.
