Abstract

The invention discloses a porous boring machine for a combined boring bar. The porous boring machine comprises a drive device, a boring bar, boring cutters, a boring platform, a deflection fine adjusting mechanism and a boring cutter adjusting mechanism, wherein the boring bar is driven by the drive device; the boring cutters are arranged on the boring bar; the deflection fine adjusting mechanism is used for adjusting the deflection of the boring bar; the boring cutter adjusting mechanism is used for adjusting the telescopic length of the boring cutters; the two boring cutters are arranged in the boring cutter mounting holes in the boring bar respectively; the boring bar is provided with deflection test holes; both ends of the boring bar are connected to movable support seats respectively; the deflection fine adjusting mechanism is positioned between the two movable support seats and is connected with the boring bar; the boring cutter adjusting mechanism is arranged in the boring cutter mounting holes and is connected with the boring cutters; and the movable support seats and the deflection fine adjusting mechanism are arranged on the boring platform. According to the porous boring machine, the combined boring bar is adopted, the problem that the deflection and the deformation of the super-long boring bar are difficult to control is solved, the deformation amount of the boring bar can be accurately adjusted, and the concentricity and other machining accuracy of machined workpieces are ensured.

Description

technical field [0001] The invention relates to the field of boring machine manufacturing, in particular to a multi-hole boring machine with a combined boring bar capable of simultaneously boring holes in workpieces, and is mainly suitable for boring long and large metal boxes. Background technique [0002] In the prior art, whether it is a CNC boring machine or a non-NC boring machine, in terms of structural design, the boring bar is a single-bar boring bar. Its shortcomings: first, it is not suitable for the boring of auto parts and the boring efficiency is low; second, because the borings in some parts are porous, the spacing and precision requirements between the holes are very strict, so the single Bar boring bar boring, it is difficult to ensure the accuracy of the boring and the accuracy between the holes. [0003] In addition, the processing quality of the cylinder on the cylinder block has an important influence on the performance of the engine, and the processing ...
