Abstract

The invention discloses an automatic abrasive band polishing special machine of a general machine crankshaft. The automatic abrasive band polishing special machine comprises a workpiece clamping partand a polishing machining part. The workpiece clamping part comprises a first base, a workpiece sliding table, a headstock and a headstock motor. The headstock is fixedly mounted on the workpiece sliding table. The polishing machining part comprises a second base, a polishing frame sliding table, a polishing frame vertical plate, polishing arms, polishing heads, a polishing clamping air cylinder,an abrasive band wheel, an abrasive band guide wheel and an abrasive band winding assembly. The middles of the two polishing arms are rotationally mounted on the polishing frame vertical plate througha transverse rotating shaft. The ends, close to the headstock, of the two polishing arms are each fixedly provided with the corresponding polishing head. A polishing mechanism swings along with rotary motion of a connecting rod bent neck, relative sliding is generated between the polishing heads and a connecting rod journal, polishing is carried out through relative sliding between the polishingheads and the rod journal, the surface roughness of a main journal and the connecting rod journal reaches Ra0.1 through the polishing effect, and any requirement for crankshaft surface roughness can be met basically; and the machine already becomes the leading product of the company for several years.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a special machine for automatic abrasive belt polishing of a crankshaft of a general machine. Background technique [0002] At present, in the processing and production of crankshafts, the processed crankshaft body needs to be ground and polished, and the grinding process is mainly to polish the neck of the crankshaft body. General machine crankshaft is one of the key parts of general machine engine. Since polishing was not paid much attention in the past, manual polishing is mainly used. Generally, workers and masters use a grinder to directly polish the crankshaft body. When the crankshaft body is polished, the crankshaft cannot be fixed after it is fixed Move, so that the local area of ​​grinding is small when grinding like this, and the operation method is simple, but the work efficiency is low, the grinding efficiency is poor, and a large amount of manpower and...
