Principle description of jaw chuck function:
（1）圆形零件装夹(1) Clamping of circular parts
通过档位手柄10挂到联动档，使卡盘前端盖1内部圆柱齿轮变换位置，一头圆柱齿轮的齿与三卡爪3上的齿条13啮合，另外一头圆柱齿轮的齿与卡盘前端盖1内部的齿轮啮合，用卡盘钥匙旋转其中一根圆柱齿轮可使三个卡盘的爪一起移动，从而实现装夹圆形工件。The gear handle 10 is linked to the linkage gear to change the position of the cylindrical gear inside the chuck front cover 1. The teeth of one cylindrical gear mesh with the rack 13 on the three jaws 3, and the teeth of the other cylindrical gear mesh with the front end cover of the chuck. 1. The internal gears are meshed. Rotating one of the cylindrical gears with the chuck key can make the jaws of the three chucks move together, so as to realize the clamping of circular workpieces.
（2）不规整零件装夹及偏心轴(2) Irregular parts clamping and eccentric shaft
通过档位手柄10挂到独自移动档，使卡盘前端盖1内部圆柱齿轮变换位置，一头圆柱齿轮的齿与三卡爪3上的齿条13啮合，另外一头圆柱齿轮的齿与卡盘前端盖1内部的齿轮脱开，用卡盘钥匙旋转其中一根圆柱齿轮只能使与它啮合一只卡爪3移动，其它二只卡爪3不移动，要移动需分别用卡盘钥匙旋转另外二根圆柱齿轮，从而实现装夹不规整工件及偏心轴。The gear handle 10 is linked to the independent moving gear to change the position of the cylindrical gear inside the front end cover 1 of the chuck. The teeth of one cylindrical gear mesh with the rack 13 on the three jaws 3, and the teeth of the other cylindrical gear mesh with the front end of the chuck. The gears inside the cover 1 are disengaged. Rotating one of the cylindrical gears with a chuck key can only make one jaw 3 meshed with it move, and the other two jaws 3 do not move. To move, you need to rotate the other with a chuck key respectively. Two cylindrical gears, so as to realize the clamping of irregular workpieces and eccentric shafts.
（3）其它工作原理(3) Other working principles
通过档位手柄10挂到空档，使卡盘前端盖1内部圆柱齿轮变换位置，一头圆柱齿轮的齿与三卡爪3上的齿条13脱开，另外一头圆柱齿轮的齿与卡盘前端盖1内部的齿轮脱开，实现空挡。设置空挡是因为装夹不规整零件及偏心轴后，可使卡盘三爪复位到中心点，进行圆形工件加工。处于空档位置，促使多用卡盘可以复位，保证档位顺利的切换。By shifting the gear handle 10 to the neutral position, the position of the cylindrical gear inside the chuck front cover 1 is changed, the teeth of one cylindrical gear are disengaged from the rack 13 on the three jaws 3, and the teeth of the other cylindrical gear are connected to the front end of the chuck. The gear inside the cover 1 is disengaged to realize neutral gear. The neutral gear is set because after clamping irregular parts and eccentric shafts, the three jaws of the chuck can be reset to the center point to process circular workpieces. In the neutral position, the multi-purpose chuck can be reset to ensure the smooth switching of gear positions.
