| description | The invention discloses a supporting and positioning device of a large overhanging cutter bar and a machining method using the supporting and positioning device, and belongs to the field of machining. The tool comprises a sleeve, the sleeve is used for being arranged on a tool bar in a sleeving mode, the tool bar and the sleeve can rotate relatively, and a tool bit is installed on the tool bar in a telescopic mode; a plurality of radial annular grooves are formed in the periphery of the sleeve, and rubber rings are arranged on the radial annular grooves. According to the supporting and positioning device of the large overhanging cutter bar, the rubber rings are used for supporting and positioning in groups, the positioning length is obviously increased relative to a hard alloy block, positioning is more reliable, the sleeve drives the rubber rings and the cutter bar to rotate relatively, relative movement between the rubber rings and parts is avoided, abrasion of the rubber rings is reduced, and the service l |
