Product Description
500mm Diameter Quick Chuck Gripper Welding Chucks For welding positioners
Three-jaw self-centering chuck uses three screws to fasten the chuck to the machine flange through the screw holes on the end face. Insert the wrench into any square hole of the gear, when the wrench is turned, the pinion will drive the wire to rotate, and through the rotation of the thread on the end face of the wire, the three claws will be driven to approach the center or separate in three directions at the same time.| Model | Required clamping force | Loading weight | Anti-grab clamping range A | Anti-grab clamping range B | Extended clamping range |
| KP200 | 200KG | 30KG | Ф110-210 | Ф20-130 | Ф5-300 |
| KP300 | 250KG | 120KG | Ф170-280 | Ф80-190 | Ф10-400 |
| KP400 | 350KG | 240KG | Ф250-380 | Ф120-250 | Ф10-500 |
| KP500 | 800KG | 600KG | Ф360-500 | Ф200-360 | Ф40-600 |

1. Regularly check the three-jaw chuck to check whether the claws, screws and springs are working properly;
2. When installing and using the three-jaw chuck, it must be fixed firmly as required
3. When the surface of the workpiece is too smooth, anti-slip agent can be applied on the surface to ensure better clamping effect
4. Try to use it in a low temperature/static environment to ensure a good use effect
5. Clean and maintain after use to keep the surface clean and increase the service life
1. According to the number of jaws of the chuck, it can be divided into: two-jaw chuck, three-jaw chuck, four-jaw chuck and special customized chuck.
2. The claws are evenly distributed on the radial movement of the welding positioner, and the three claws of the three-jaw chuck are evenly distributed on the clamping mechanism on the (120°) chuck body.
3. The three jaws of the three-jaw self-centering chuck move at the same time and self-center, which can complete automatic centering
4. The clamping is convenient and fast, only need the sleeve, copper piece and wrench, no other auxiliary positioning devices are needed.
