Described slotted weight is equal slotted weights movably at the balance pivot two ends.
The other end of described main lever also is provided with the fine setting lever and can finely tuning the fine setting sign indicating number that lever moves.
Advantage of the present utility model is as follows:
1, pressure regulating mechanism of the present utility model can directly be read actual pressure value from the rule of main lever, so the pressure adjustment process is simple, direct, practical.
2, the slotted weight in the utility model pressure regulating mechanism can move at the fulcrum two ends, according to lever principle, slotted weight to the place ahead of fulcrum to moving then pressure boost, otherwise, pressure is then reduced to moving in rear to fulcrum, can overcome the pressure that produces by the gravity of mechanical linkage part and chopper anchor clamps self, make the I of last welding pressure reach 0.Therefore, but bonding wire footpath can be less than 0.02mm, and can be used for bearing the less delicate workpieces of pressure, makes the welding expanded range.
3, the fine setting calibrated section in the utility model pressure regulating mechanism can conveniently finely tune and calibrate.
4, the utility model pressure regulating mechanism adopts lever principle, does not have distortion, and error is little.
