Positioning device for rapid cutting of annular parts

Abstract

The invention discloses a positioning device for quickly cutting ring-shaped parts, which is used for positioning the workpiece to be cut before cutting, comprising: a frame, in the form of a rectangle, including a bottom frame, a vertical frame and a top frame; a first truss set At one-third of the bottom frame, it is used to fix the bottom end of the workpiece to be cut; the perforated truss includes the first perforated truss and the second perforated truss placed in parallel, the first perforated truss and the second perforated truss Both ends of the truss are fixed on the vertical frames on both sides, and the first perforated truss and the second perforated truss have threaded holes; positioning rods include short positioning rods and long positioning rods, short positioning rods and long positioning rods The rods pass through the threaded holes and are set between the first truss with holes and the second truss with holes to fix the middle part of the workpiece to be cut; the two second trusses and the third truss are respectively set on the left side of the opening of the top frame. The side and the right side of the opening are used to fix the top of the workpiece to be cut.

Description

technical field [0001] The invention relates to a repair tool for ring-shaped sleeve parts in the fields of automobiles and aerospace, in particular to a positioning device for quickly cutting ring-shaped parts. Background technique [0002] At present, when producing motor stators in China, related companies that produce motors usually conduct failure analysis on failed products and separate and extract recyclable raw materials according to the cause of failure for the purpose of saving costs. When the stator aluminum sleeve fails and the rest is intact, it is usually necessary to cut off the aluminum sleeve, and then reuse the stator return line. Due to the high price of purchased large-scale professional automatic cutting equipment, maintenance is complicated. In order to meet the needs of cost saving, efficiency improvement and fast cutting, this patent mainly meets the cutting of ring-shaped parts. In the process of cutting ring-shaped parts, due to the close connecti...
