Description

A kind of projection welder device
Technical field
The utility model relates to a kind of welding equipment, especially relates to a kind of projection welder device.
Background technology
At present, in automobile production, carry out nut or bolt welding on to large-scale stamping parts (as car front door inner panel, hood inner panel, car back door inner panel, car back door inner panel etc.) time, normally first nut or bolt are placed on to the position that needs welding on large-scale stamping parts, then weld by projection welder.But because the workpiece area of large-scale stamping parts is larger, tend to be subject to the restriction of welder frame, the nut in workpiece centre position or bolt welding are very difficult, be that welding work pieces area is very limited, whole workpiece to be welded and needed repeatedly again to dismantle and clamp, not only waste time and energy, and be difficult to ensure again to clamp the accuracy of position at every turn, this can directly affect the quality of final products.
Another technological deficiency that tradition projection welder exists is in the time carrying out nut projection welding, need electric current first flow through nut, workpiece, be directly delivered to again on electrode, and in the time of hold-down nut, if adopt electric conductivity alignment pin, can make part electric current be directly delivered on electrode by nut, conduction alignment pin, will cause like this current distributing, thereby cause welding unsuccessfully or need to provide more high-power projection welder just can complete projection welding.Therefore, in most situation, the plastics alignment pins that adopt are fixed nut more, but because nut packs into and taking-up frequently, and friction can be by the wearing and tearing of plastics alignment pin repeatedly, and then cause locating inaccurate, directly affect follow-up welding quality.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of simple in structure, easy to operate projection welder device in order to overcome the defect that above-mentioned prior art exists, unrestricted to reach welding work pieces area, can effectively reduce Workpiece clamping number of times, durable for a long time, the object saving production cost.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of projection welder device, this device comprises projection welder body, upper electrode arm, lower electrode holder, top electrode, bottom electrode and controller, described top electrode is arranged on projection welder body by upper electrode arm, described bottom electrode is arranged on projection welder body by lower electrode holder and is positioned at the below of described top electrode, described lower electrode holder, upper electrode arm are all connected by slide rail and projection welder body, described controller is arranged on the sidewall of projection welder body, and controller is connected with lower electrode holder, upper electrode arm respectively by the interior circuit of establishing.
Described projection welder body comprises lower shoe, bracing frame and header board, the bottom of described bracing frame is arranged on lower shoe, and the upper portion side wall of bracing frame has groove, in described groove, is provided with slide rail, described header board is positioned at the top of lower shoe, and is slidably connected by slide rail and bracing frame.
Described lower electrode holder is arranged on lower shoe by slide rail, and described upper electrode arm is arranged on header board by slide rail, and described lower electrode holder, upper electrode arm are all slidably connected by slide rail and projection welder body.
Described bottom electrode comprises lower electrode tip, cylindric bottom electrode body and alignment pin, and the top of described bottom electrode body is embedded with lower electrode tip, and described alignment pin is arranged on lower electrode tip.
The bottom of described bottom electrode body is provided with external screw thread, and described lower electrode holder top is provided with the internal thread hole matching with described external screw thread, and the bottom of described bottom electrode body is fixed on lower electrode holder by nut and pad.
Described alignment pin adopts ceramic material to form.
When work, first upper electrode arm, lower electrode holder are carried out the position adjustment of horizontal direction by controller, until top electrode and bottom electrode are aligned with each other, again the header board on bracing frame is carried out the position adjustment of vertical direction, until the vertical range between top electrode and bottom electrode reaches setting value, by the alignment pin on bottom electrode, workpiece is positioned again, after end to be positioned, can weld workpiece.
Compared with prior art, the utlity model has following characteristics:
1. adopt slide rail design, and top electrode is separated with bottom electrode, make welding work pieces area not be subject to the restriction of projection welder rack construction size, the scope of application is wider;
2. can effectively reduce Workpiece clamping number of times, improve man-haur efficiency, save production cost;
3. alignment pin simple in structure, easy to operate, to have adopted ceramic material to make is more durable, safe and reliable.
