The invention belongs to the technical field of worm
machining, and particularly relates to a worm
machining thread
grinding and
polishing device which comprises a
machine tool body, a worm body is installed on one side of the upper portion of the
machine tool body, a supporting frame is fixed to one side of the top end of the
machine tool body, a moving seat is arranged in the supporting frame, and a lifting seat is arranged below the moving seat. A mounting base is mounted at the bottom end of the lifting base, a
cutting tool bit is fixed to the bottom end of the mounting base, two
polishing heads are arranged below the mounting base, a movable cavity is formed in the bottom end of the mounting base, a connecting box is slidably connected into the movable cavity, an electric telescopic rod is mounted in the movable cavity, and a second motor is mounted in the connecting box; the
grinding head is driven by the electric telescopic rod to move downwards so that the
grinding head can make contact with the threaded surface of the worm main body, the grinding head is driven by the second motor to
grind burrs and stripes of threads, meanwhile,
metal powder can be collected through the dust collection manifold, and the
metal powder can be prevented from splashing to the ground or the top end of the
machine tool main body.
