Problems solved by technology

[0002] At present, in the machining process of the workpiece, especially the machining of the inner hole of the workpiece, due to the limited processing range of the general tool, it is impossible to complete all the chamfering of the inner hole, so the tool bar is usually used for processing, and one end of the tool bar is The Morse taper tool holder is connected to the main shaft of the machine tool, and the other end is equipped with a tool, which is driven by the tool bar for processing. Because the tool bar of this processing method is relatively long, the tool is easy to shake and has poor stability. Breaking force occurs, so that the processed chamfer is uneven, and the operation risk is high

Abstract

The invention relates to a mechanical part chamfer processing mechanism. The mechanical part chamfer processing mechanism comprises a workbench and a cutter bar. A positioning device is arranged between the workbench and the cutter bar. The positioning device comprises a positioning shaft, a bearing and a protective cover. The outer ring of the bearing is fixedly connected to the positioning shaft. The inner ring of the bearing is fixedly connected to the protective cover. One end of the cutter bar provided with a cutter is provided with a positioning pin and the positioning pin is fixedly connected to the protective cover of the positioning device so that cutter bar two-point support is formed in processing and thus cutter bar rigidity is improved, cutter shaking is reduced, stability in cutting is improved, fracture is avoided in processing, the processed chamfer has good uniformity and operation safety is high.

Description

technical field [0001] The invention relates to a mechanical processing device, in particular to a device for chamfering workpiece holes Background technique [0002] At present, in the machining process of the workpiece, especially the machining of the inner hole of the workpiece, due to the limited processing range of the general tool, it is impossible to complete all the chamfering of the inner hole, so the tool bar is usually used for processing, and one end of the tool bar is The Morse taper tool holder is connected to the main shaft of the machine tool, and the other end is equipped with a tool, which is driven by the tool bar for processing. Because the tool bar of this processing method is relatively long, the tool is easy to shake and has poor stability. A broken force phenomenon is generated, so that the processed chamfer is uneven, and the operation risk is high. Contents of the invention [0003] The problem to be solved by the present invention is to provide ...
