Problems solved by technology

[0002] When processing the inner hole of the workpiece, it needs to go through two processes of rough boring and fine boring, but in some cases, fine boring cannot meet the requirements of surface roughness, and a rolling process needs to be added; Among them, rough boring tools, fine boring tools and rollers need to be used, and processing tools need to be frequently replaced on the boring bar, which causes complicated processing procedures and reduces processing efficiency
The existing technology needs to adjust the rough boring tool, fine boring tool and roller separately. The roller adjustment needs to adjust the rear limit stop to the front of the roller, and it is necessary to pad the tough part of the rough boring tool and the fine boring tool with copper skin. Reduce the scratches when the machined hole is retracted, and the processing efficiency is improved, but the pass rate cannot be guaranteed, and the steps are more cumbersome, which is not conducive to rapid production

Abstract

The invention belongs to the technical field of inner hole machining, and particularly discloses an adjustable combined boring head which comprises a boring head piston rod, a boring head body slidably connected to the outer side of the boring head piston rod in a sleeving mode and a push broach piston rod slidably connected to the inner side of the boring head piston rod in a sleeving mode. An adjusting screw rod is arranged at the axis of the end part of the boring head body, a rough boring adjusting expansion block and a fine boring adjusting expansion block which are matched with the rough boring cutter and the fine boring cutter are respectively in threaded connection with the adjusting screw rod, the expansion directions of the rough boring adjusting expansion block and the fine boring adjusting expansion block are the same, one end of the adjusting screw rod is in threaded connection with the boring head body, and the other end of the adjusting screw rod is in threaded connection with the boring head body. And the other end is propped against the output end of the push broach piston rod. The purposes of hydraulic automatic adjustment, improvement of operation safety of a machine tool and improvement of boring efficiency are achieved, the inner hole of the cylinder barrel is sequentially machined from rough boring to fine boring to tumbling, the electric charge expenditure is reduced, the abrasion rate of the machine tool is reduced, the labor intensity is reduced, and the working safety is guaranteed.
