The present invention relates to an object fixing chuck including a rotary shaft having a central shaft and a central assist shaft joined to and separated from the central shaft and including a support unit on a joint portion; a rotary plate joined to the central shaft and including pin mounting holes and rotary protrusions at intervals on the inner circumference; a driver plate arranged on the outer side of the rotary plate and including a drive through-hole on one side and a pin insertion hole in a position corresponding to the pin mounting hole; a drive pin having a pin fixing unit arranged on the rotary plate and a pin body penetrating through the drive through-hole and formed on one side of the pin fixing unit to be integrated; a drive block joined to the drive pin and supplying torque to the drive pin, driver plate, and the rotary plate; a bearing block arranged inside the rotary plate and including a pin connecting hole at a position corresponding to the pin mounting hole and a cover locking protrusion on the outer side; rotary pins fitted and joined to the pin insertion hole, pin mounting hole, and the pin connecting hole and including a rotary joining unit inside and a protrusion insertion groove into which the rotary protrusions are inserted on the outer side; a chuck cover receiving the rotary plate and driver plate inside and receiving a part of the bearing block inside; and a jaw joined to the rotary joining units of the rotary pins and fixating an object to be processed when supplying torque due to the operation of the drive block. According to an embodiment of the present invention, the operation of the jaw fixating the object to be processed with the rotary pins interlocked with the rotation of the driver block can be easily controlled. In addition, the present invention obtains an effect of easily assembling and separating as the whole structure is simple. |
