The utility model is achieved through the following technical solutions：
A kind of abnormal screw thread parts retainer, including：Chuck and more than two grip blocks along chuck circumferentially；
One end of grip block is mounted on the end face of chuck, and the other end is threaded respectively, more than two grip blocks
The opposite internal thread formed with abnormal screw thread part screw-thread fit of screw thread, more than two grip blocks can be synchronized circumferentially to be turned along chuck
It is dynamic, realize the centering clamping to abnormal screw thread part；More than two grip blocks can be synchronized and be moved radially along chuck, be realized to difference
The clamping of the abnormal screw thread part of diameter.
Further, the grip block includes：Movable jaw, connecting rod and screw thread gripper jaw；
The bottom surface of the movable jaw is machined with the limit card slot for coordinating with chuck；
The end of the screw thread gripper jaw is machined with the screw thread for coordinating with abnormal screw thread part, the screw pitch of screw thread with it is different
The screw pitch of shape thread part is identical；
The limit card slot of movable jaw one end is mounted on chuck, the screw thread that the other end passes through connecting rod and screw thread gripper jaw
Opposite end forms zigzag structure after being fixedly connected.
Further, the grip block further includes fixed bearing bar, and fixed bearing bar skewed horizontal load is in connecting rod and activity
Between claw, both ends are fixed with connecting rod and movable jaw respectively.
Further, more than two grip blocks are circumferentially uniformly distributed along chuck.
Further, connecting rod and the connection type of screw thread gripper jaw and movable jaw are welding.
Further, fixed bearing bar and connecting rod and the connection type of movable jaw are welding.
Further, the movable jaw, connecting rod, fixed bearing bar material select steel alloy；The screw clamp
Hold the material selection brass of pawl.
Advantageous effect：The utility model solves special-shaped spiral shell by the cooperation of the screw thread and abnormal screw thread part of grip block
The clamping of line part is difficult, the problem of can not feeling relieved and can not reprocess to abnormal screw thread parts repair, with easy to operate, unloads
Carried convenient, versatile feature have filled up the blank in clamping field before abnormal screw thread parts repair.
