Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tool for drilling a piston rod. Background Art

[0002] The piston rod is the main component of the press, and each press requires four pieces. The interior of the piston rod is provided with an axial channel for conveying lubricating oil. Therefore, the piston rod body needs to be drilled after the initial processing is completed. The traditional processing method is to clamp it with a chuck and a center frame on the C630 drilling machine, install the drill bit on the tailstock, and rely on the operator to pull the tailstock back and forth to drill while the piston rod is in a rotating state. Since the backcutting operation needs to be carried out in time during the processing, otherwise the drill bit is easily broken and the piston rod is scrapped, the drill bit needs to be pulled out for backcutting after drilling for a period of time. The labor intensity is high and the labor efficiency is low. The length of the piston rod will increase the processing time. There are also special deep hole drilling machines, but they are expensive. When the processing volume of the piston rod is not large, purchasing a special deep hole drilling machine will bring a large economic burden to the enterprise. Therefore, it is necessary to design a tooling for piston rod drilling that can be used on an ordinary drilling machine, so as to achieve the purpose of reducing labor intensity and improving processing efficiency on the basis of ensuring drilling quality.
