Automatic Armature Spot Welder Commutator Hot Staking Machine

Electric Motor Commutator Spot Welder

The commutator spot welding machine is used for motor armature rotor commutator hot staking and the spot welding machine is suitable for three shifts continuous production,greatly improve production efficiency.

Automatic Armature Spot Welder Commutator Hot Staking Machine

Hotstaking Machine Features

1. The commutator spot welding machine is used for motor armature rotor commutator hot stacking

2. The commutator hot staking machine is suitable for three shifts continuous production

3. Production efficiencyshift output is about 1500

4. Spot welding machine Loading method: manually loading/unloading

5. Dynamic display the parameter, including the shift output, accumulate output, cycle time,etc., if there is abnormal during production, the HMI will alarm

6. It has production(jog and auto) and commissioning mode

7. The parameter can be saved as per the armature model No., call-out the welding parameter through the Miyachi power source

8. It has welding limit function to remind operator to change the tungsten rod in time


Commutator hotstaking Process

1. Manually place the armature on the V block, positioning,

2. start the machine,

3. machine clamp the armature,

4. positioning cylinder withdraw,

5. servo motor executes indexing compensation angle,

6. automatically indexing, automatically welding, automatically detecting the welding pressure and do the related treatment,

7. manually take the welded armature away from the V block
