Multi-head rolling surface polishing cutter

Abstract

The invention discloses a multi-head rolling surface polishing cutter, and belongs to the technical field of machining cutters. The multi-head rolling surface polishing cutter comprises a cutter rest and five cutter bits, wherein the cutter bits are rolling bits, and mainly consist of balls, support frames, wear resistant plates, lower pressing plates, compression springs, upper pressing plates, pressing screws and the like. The cutter rest can be connected with a machine tool spindle through a Morse taper handle and the like; the balls are put into the support frames, and are pressed with the wear resistant plates having circular grooves; the wear resistant plates are pressed with the lower pressing plates and the upper pressing plates; and the compression springs are mounted between the upper and lower pressing plates. The multi-head rolling surface polishing cutter has the following advantages: through the cutter bit mechanical rolling effect, the material surface smoothness and levelness are improved, the surface pressure stress is improved, the material surface grain size is reduced, and the material surface performance is enhanced; and through the cutter multi-head design, the cutter machining efficiency and using performance are improved.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a multi-head rolling surface finishing tool. Background technique [0002] The rolling knife uses the plastic deformation of the metal to flatten the microscopic unevenness of the surface of the workpiece, so as to achieve the purpose of changing the surface structure, mechanical properties, shape and size. No matter what kind of machining tool is used to process the parts, there will always be tiny uneven tool marks on the surface of the parts, and there will be staggered peaks and valleys. Rolling knife is a mechanical non-cutting plastic processing method that uses the principle of mechanical extrusion to obtain a mirror-like metal surface. [0003] It is a kind of pressure finishing process, which uses the cold plasticity characteristics of metal at room temperature, and uses rolling tools to apply a certain pressure on the surface of the workpiece, so that the metal...

Problems solved by technology

However, there are still some areas that need to be improved in the currently commonly used rolling tools, which are mainly reflected in two aspects. One is that most of the balls in the cutter head are welded or difficult to adjust. When the balls are damaged or worn, it is difficult to replace them; Most of the pressing tools are single-rolling-head tools used in lathes, and the rolling efficiency is low, so it is difficult to apply to the rolling of large planes
