Definitions
- the present invention relates to a resistance welding clamp of the type comprising two electrode-carrying arms, one of which is movable relative to the other, the relative movement of the arms being produced by an electric actuator.
- These clamps can have very varied shapes, classifiable into two general categories, namely those in which the movement of the movable arm is a rotational displacement (clamp in X) and those in which the movement of the movable arm is a translational displacement ( pliers in C or J).
- resistance welding tongs are actuated by hydraulic or pneumatic cylinders and have a number of very common drawbacks.
- a stud welding device (US-A-5 321 226) and a spot welding clamp (JP-A-09 155 558) are also known, both using a linear magnetic motor.
- Such a motor works in all or nothing and therefore does not make it possible to ensure and adjust the succession of displacements necessary for the proper functioning of a clamp, for example the adjustment of the pressure force, and to perform pulsed welding. .
- the present invention aims to overcome these drawbacks of the known resistance clamps with electric jack.
- the clamp according to the invention is characterized in that the electric actuator comprises a linear electric induction motor with conductive armature and planar inductor.
- the electric actuator comprises at least two electric motors with conductive armature with common guidance.
- the armature is fixed and the inductor is movable.
- the armature is mobile and the inductor is fixed.
