Cutter tool with fine adjustment for rough and fine hole boring

Abstract

The invention relates to a cutter tool with fine adjustment for rough and fine hole boring. The cutter tool comprises a cutter handle seat, a cutter bar seat and boring cutter heads, wherein the cutter handle seat is fixed on a main shaft of a boring machine; the cutter bar seat is connected to the cutter handle seat; the boring cutter heads are fixed on the cutter bar seat; the cutter tool is characterized in that: the cutter bar seat is eccentrically connected to the cutter handle seat and is provided with two mounting parts for fixing the boring cutter heads; and the cutter bar seat can be provided with two boring cutter heads at most. In the cutter tool, the cutter bar seat is eccentrically connected to the cutter handle seat, so that the cutter bar seat and the cutter handle seat produce an eccentric distance e; the processing radius of boring cutters can be changed by adjusting the relative angular relation of the center of a cutter bar and the center of a cutter handle, and the adjustment accuracy can be improved by performing the adjustment finely; meanwhile, the cutter bar seat is provided with a rough boring cutter head and a fine boring cutter head; the rough and fine boring can be finished by only clamping the cutter tool and a workpiece at one time, so that the working efficiency and the processing accuracy are improved; the cutter tool has a simple structure, and is easy to process and low in manufacturing cost; and a hole processed by the cutter tool has a large aperture range and high rigidity, so that the processing accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of machine tools, and relates to a fine-adjustable tool for rough and fine boring. technical background [0002] In mechanical processing, the processing of the holes on the box and the shell is generally processed on a boring machine. However, there is no relevant mechanism to ensure the dimensional accuracy of the hole machining on the existing boring machine, which can only be guaranteed by the adjustment of the cutter. In the prior art, fine-tuning boring tools are often used to realize the fine-tuning. There are many types of fine-tuning. Generally, linear movement is used. According to the specific form of linear movement, it can be divided into: screw feed type, moving with guide rail or moving with guide column, etc. . Since there are many parts and connections among the above-mentioned moving mechanisms, the rigidity is poor, and they are all designed for single boring heads. During rough and fine...

Problems solved by technology

Since there are many parts and connections among the above-mentioned moving mechanisms, the rigidity is poor, and they are all designed for single boring heads. During rough and fine boring, tool change and adjustment are required. Once the boring heads are worn out, the micro boring The adjustment is more complicated, so that the whole processing cannot be continuous, not only the work efficiency is low but also the processing accuracy is low.
