Abstract
A single-sided spot welding equipment includes a welding torch with two or more electrodes, a mover to drive the welding torch to move away from or toward the workpiece, a controller for controlling the welding torch and the mover, and a support to position the welding torch in a prescribed height. The welding torch may shift horizontally on the support.
Description
The present invention relates to spot-welding equipment, be specifically related to one side spot welding apparatus.
Generally, spot-welding equipment is for the workpiece of being forced by electrode to keep together, and when making electric current pass through wherein, the heat that produces because of resistance makes the metal surface welded together.These two the current impulse heating that the contact-making surface in the electric current concentration zones is high ampere form so-called solder joint point nuclear at the interface on this two surface.
But when adopting above-mentioned welding equipment to be welded to plate on the tubular workpieces, because the two is by the electrode location and maintains that they just may deform.
For fear of the distortion of workpiece, adopted one-sided welding equipment.Fig. 1 shows the welding gun of understanding traditional one-sided welding equipment.In order to be engaged in welding, the operator holds handle 1 with one the tip 2 of this welding gun is moved to belonging positions in the work, is located at operating switch 3 on the welding gun precalculated position with the another hand starting then.
But the shortcoming of this traditional one-sided welding equipment is to be difficult to make tip to navigate to the required solder joint place of workpiece; Also because whole weld job is by manual operations, operating personnel make every effort to avoid such weld job.
The present invention promptly is devoted to solve the problems referred to above in the prior art.
One of purpose of the present invention is to provide a kind of one-sided means of spot welds equipment, and it can make welding gun accurately be positioned on the solder joint required in the work and can not increase the weight of operator's burden, thereby can improve work efficiency.
To achieve these goals, one side spot welding apparatus of the present invention comprises welding gun with two or more electrode, be used for driving actuator that welding gun shifts near or move apart with respect to workpiece, be used for controlling the controller of this welding gun and actuator and be used for making welding gun to navigate to the supporting member of predetermined altitude, and this welding gun can flatly slide on this supporting member.
Below accompanying drawing be a part of this specification, these annexed drawings set forth embodiments of the invention, they are used for explaining principle of the present invention with supporting paper.
Fig. 1 is a perspective view, shows traditional one side spot welding apparatus of understanding in the prior art;
Fig. 2 is a perspective view, shows the one side spot welding apparatus of understanding most preferred embodiment of the present invention; And
Fig. 3 is the fragmentary cross-sectional view of one side spot welding apparatus shown in Figure 2.
Most preferred embodiment below in conjunction with description of drawings one side spot welding apparatus of the present invention.
Fig. 2 and 3 shows clear one side spot welding apparatus of the present invention.
One side spot welding apparatus of the present invention comprises: have two or more electrode 11 welding gun 10, be used for driving actuator 20 that welding gun 10 shifts near and away workpiece, be used for the supporting member 40 controlling the controller 30 of actuator 20 and be used for supporting welding gun 10.
As shown in Figure 3, actuator 20 comprises: have open top and the carriage 21 of the hole 21a of two predetermined diameters is arranged on antetheca, and hold by each of the outstanding piston rod 22a welding gun 10 of each hole 21a and piston rod 22a and to be connected.
Supporting member 40 comprises that horizontal guide rail 42, the slide block of installing around this horizontal guide rail 42 slidably 41, two opposite ends of supporting horizontal guide rail 42 securely are positioned this rail the vertical support frame 43 of predetermined altitude.
The following describes the welding method of one side spot welding apparatus of the present invention.
At first workpiece (tubular piece and plate) 100 is placed the welding position that has predetermined gap with the electrode tip.Moving slider 41 then, and electrode 11 is positioned at and corresponding position, welding position, connect main switch 34.Immediately, central processing unit 33 sends a control signal to control valve 32, starts cylinder 22 electrode 11 is contacted with workpiece.When electrode 11 contacts with workpiece, the electric current of high ampere just flows to electrode 11 by welding gauge tap 31, makes that the contact-making surface in this electric current contact zone is the current impulse heating of high ampere, forms solder joint point and examines.Behind one section predetermined instant, just short the causing of central processing unit 33 welded the electric current that switch 31 interruptions are crossed along described electrode stream.When control valve 32 returns its initial position, just finished a circulation of spot welding operation.
When on parallel direction, needing this weld job of repetition, only need along track 42 sliding sliders 41 and connect welding gauge tap 31 to get final product.
As mentioned above, when using one side spot welding apparatus of the present invention, when carrying out weld job, the operator need not grip welding gun, thereby can alleviate operator's labour and save man-hour.In addition since the interaction of above-mentioned horizontal guide rail and cylinder with and the effect of going up predetermined power is arranged, thereby electrode can be at the solder joint of workpiece convergence workpiece accurately, so can make welding product and can carry out large-scale production by high-quality.
