Special machine tool for polishing and polishing method thereof

Abstract

The invention discloses a special machine tool for polishing. The special machine tool comprises at least one main shaft, at least one main shaft driving device, at least one polishing brush, at least one lifting sliding table, at least one sliding table driving device, a machine tool bed, a base, a workbench and at least one rotary chuck. The machine tool bed and the workbench are installed on the base. The main shafts, the main shaft driving devices and the polishing brushes are connected to the machine tool bed in a vertical sliding mode through the lifting sliding tables. The polishing brushes are detachably installed at the lower ends of the main shafts. The rotary chucks are detachably installed on the workbench. The polishing brushes are in one-to-one correspondence with the rotary chucks. The lifting sliding tables are adopted for driving the rotating main shafts and the polishing brushes to ascend and descend to polish workpieces on the rotary chucks, polishing is rapid, effective and clean, workpiece surfaces can be prevented from being damaged, and burrs and flash in the workpieces can be thoroughly removed. The two problems that the surfaces of workpieces are damaged and flash is difficult to remove through a traditional polishing device are solved.

Description

technical field [0001] The invention relates to a special machine tool for polishing, in particular to a special machine tool for polishing output bracket shells and other similar parts. Background technique [0002] The current processing of the inner bottom plane of the output bracket housing and other similar parts is a turning process, and burrs and flashes are generated after turning. Using traditional chamfering and polishing to remove burrs and flashes is not only labor-intensive and time-consuming; traditional polishing also has the problem of damaging the workpiece with grinding wheels (destroying the turning lines on the surface of the workpiece); using soft materials (such as cloth) ) polishing, flashing is difficult to remove. [0003] In order to effectively remove burrs and flashes, a special polishing machine is used. The polishing brush of the polishing machine is made of special materials, which can exert a certain pressure to make the polishing fast, effe...
