Thread self-locking type tool fixture for rectangular workpiece

Abstract

The invention discloses a thread self-locking type tool fixture for a rectangular workpiece. The thread self-locking type tool fixture comprises a rectangular bottom plate, an L-shaped positioning stopping block for positioning the workpiece, a disc-shaped pressure head for tightly pressing the workpiece, a driving threaded rod for driving the disc-shaped pressure head, a threaded sleeve which is matched with the driving threaded rod to form a thread transmission pair and a supporting base for installing the threaded sleeve. The L-shaped positioning stopping block is fixedly installed on the upper side of one end of the rectangular bottom plate. The supporting base is fixedly installed on the upper side of the other end of the rectangular bottom plate. The threaded sleeve is fixedly installed on the supporting base and internally provided with the driving threaded rod. The disc-shaped pressure head is fixedly installed at the end of the inner side of the driving threaded rod. The thread self-locking type tool fixture for the rectangular workpiece has the following characteristics of being good in self-locking performance, reasonable in design, convenient to operate, simple in structure, convenient to disassemble, very long in service life, wide in application range, low in production cost and convenient to apply and popularize.

Description
