Abstract

The invention relates to a steel ball positioning and fastening type die handle for machining internal and external threads and a using method thereof. The steel ball positioning and fastening type die handle for machining internal and external threads comprises a cone mandrel. A shaft lever at one end of the cone mandrel is sleeved with a rolling and sliding sleeve. A cone which is connected with a cone hole of a tail center sleeve of a lathe is arranged at the other end of the cone mandrel. A mounting hole is formed in one end face of the rolling and sliding sleeve and can be used for mounting a circular die and a screw tap fixing piece used for fixing a screw tap. A plurality of positioning steel balls which can move up and down are arranged on the side wall of the mounting hole at intervals. One end of the rolling and sliding sleeve is further sleeved with a locking sleeve, and the locking sleeve presses the positioning steel balls after sliding towards the cone, so that the circular die or the screw tap fixing piece is locked through the positioning steel balls. The steel ball positioning and fastening type die handle is simple in structure, convenient to mount and dismount, and wide in application range.

Description

technical field [0001] The invention relates to a steel ball positioning and fastening type die holder for processing internal and external threads and a use method thereof. Background technique [0002] In maintenance work, it is common to process internal and external threads. When processing internal and external threads, workpieces often need to be loaded and unloaded due to different thread parameters. Due to the complex structure of equipment for processing internal and external threads and low loading and unloading efficiency, the processing efficiency is low. For this reason, need a kind of steel ball positioning fastening type die holder of processing internal and external threads. Contents of the invention [0003] The purpose of the present invention is to provide a steel ball positioning and fastening type die holder for processing internal and external threads and its use method, which not only has a simple structure, but also is convenient to assemble and di...
