Automatic feeding device for piston pin hole machining

The utility model belongs to the technical field of piston machining, discloses an automatic feeding device for piston pin hole machining, and mainly aims at solving the problems that an existing manual feeding mode is high in labor intensity and low in working efficiency, and an alignment clamping device is complex in structure. According to the system, the alignment mechanism and the clamping mechanism are separately arranged, the piston element aligned in the alignment mechanism is clamped to the clamping mechanism by moving the clamping jaw to be clamped and machined, the working procedures are clear, the structure is simple, the production cost of the whole equipment is low, and the cost performance is higher; meanwhile, the alignment mechanism is further provided with the feeding device, the piston elements are conveyed to the alignment mechanism through the feeding device, the whole process is automatic, workers only need to correctly place the piston elements into the feeding device, the labor intensi
