Abstract
This model utility relates to a resistance spot welding head which is characterized in that the contact surface between an electrode head for connecting the air cylinder and a steel plate to be welded is designed into a rectangle; an anti-rotation rod is sleeved on the periphery of the air cylinder to prevent the air cylinder to be form being moved during the working process. The utility model has the advantages that since the fixed electrode head is changed into a rectangular copper square block, the steel plate to be welded is closely fitted with the fixed electrode head, the problems of sunken soldered points and distortion can be overcome, and the quality of the welded appearance is greatly improved; more importantly, the rectangle surface designed in the position as well as the surface of the cylindrical electrode head is greatly increased, and the quality accidents caused by long-term use of the electrode head are eliminated such as false welding, unsoldering, soldered point concavity, distortion, and the like; and the problems of false welding, unsoldering, soldered point concavity and distortion which are caused since the electrode head is not aligned are avoided.
Description
Technical field
The utility model relates to a kind of spot welding soldering turret, particularly relates to a kind of resistance spot welding soldering turret.
Background technology
The resistance spot welding soldering turret that automobile body welding is used is when welding, the fixed electrode head is close to steel plate to be welded, promote the traveling electrode head along the cylinder lengthwise movement by cylinder then, with first extruding of fixed electrode steel plate to be welded, and pass to certain electric current simultaneously, the lasting regular hour makes metal alloying together, reaches welding effect.This resistance spot welding is in welding process, because the power-on and power-off cartridge is all thinner, and by employee's manual operations, is difficult to guarantee that electrode is vertical in steel plate to be welded, causes the defectives such as depression, distortion of solder joint easily, causes the body quality problem.Moreover, also, cause even more serious defectives such as sealing-off easily owing to reasons such as electrode tip bending cause electrode tip to misalign.Soldering turret among the figure B because the axle rotation that the traveling electrode head circumference moves also can cause electrode tip to misalign, causes quality accident in cylinder in a large amount of, long work.And in long-term use, the axle that the traveling electrode head circumference moves in cylinder rotates, and causes electrode to misalign, and problems such as rosin joint, sealing-off, solder joint depression, distortion occur.
Summary of the invention
The purpose of this utility model just provides the point of resistance soldering turret of a kind of anti-distortion, anti-depression, anti-sealing-off, anti-rosin joint.
Solution of the present utility model is such: the electrode tip that cylinder is connected and the contact-making surface of steel plate to be welded are for being designed to rectangle, because fixed electrode changes the copper square of rectangle first watch into, steel plate to be welded and fixed electrode head fit tightly, can overcome solder joint depression, distortion problem, improve the presentation quality of welding greatly.The more important thing is because the cuboid surface of design and increase greatly herein, eliminated because electrode tip is long-term and used quality accidents such as rosin joint that the electrode tip that causes misaligns and cause, sealing-off, solder joint depression, distortion with respect to former cylinder electrode head surface is long-pending.
If be connected to the anti-rotation bar in described cylinder outer race, the anti-rotation bar is along the setting of cylinder moving direction, has controlled the traveling electrode head effectively and has rotated, and has prevented because electrode tip misaligns problems such as the rosin joint that causes, sealing-off, solder joint depression, distortion.
The utility model has the advantages that anti-distortion, anti-depression, anti-sealing-off, anti-rosin joint, guarantee welding quality.
Description of drawings
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is second kind of structural representation of the present utility model.
The specific embodiment
Cylinder 1 of the present utility model connects electrode tip 2, and described electrode tip 2 is a rectangle with the contact-making surface of steel plate to be welded.
Described electrode tip 2 is that the bottom is big, the shape that solder side is little.
In the present embodiment, described electrode tip 2 is that the bottom is big, little stepped of solder side.
During welding, earlier with fixed electrode head applying steel plate to be welded surface, cylinder promotes the traveling electrode head then, pressing steel plate, and energising reaches the welding purpose.
Because fixed electrode changes the copper square of rectangle into first watch, steel plate to be welded and fixed electrode head fit tightly, and can overcome solder joint depression, distortion problem, have improved the presentation quality of welding greatly.The more important thing is because the cuboid surface of design and increase greatly herein, eliminated because electrode tip is long-term and used quality accidents such as rosin joint that the electrode tip that causes misaligns and cause, sealing-off, solder joint depression, distortion with respect to former cylinder electrode head surface is long-pending.
Described cylinder 1 outer race is connected to anti-rotation bar 3, and anti-rotation bar 3 is along cylinder 1 direction of motion setting.Increased the anti-rotation bar newly, controlled the traveling electrode head effectively and rotated, prevented because electrode tip misaligns problems such as the rosin joint that causes, sealing-off, solder joint depression, distortion.
In the present embodiment, electrode tip 2 is to adopt copper material.
The utility model can also be applied to the welding of others except that being used for automobile body welding.
