Technical Field

The utility model relates to the technical field of metal processing equipment, in particular to an automatic milling processing device for a drilling machine.

Background Art

In the prior art, a drilling machine refers to a machine tool that mainly uses a drill bit to process holes on a workpiece. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. The structure of a traditional plane drilling machine is relatively simple. When different processing is required for the workpiece, different drill bits or different equipment need to be replaced for drilling and milling, which causes a great waste of time. The milling and drilling machine is one of the main mechanical processing equipment and is widely used in mechanical processing. The method of processing a workpiece with a milling cutter on a milling and drilling machine is called milling. It can be used to process planes, steps, and inclined surfaces. , grooves, formed surfaces, gears and cutting, etc. During the processing, people clamp the parts on the limit seat through the clamping mechanism, and then slide the milling device to one end of the part to mill the surface of the part. After milling, the milling device withdraws, and then slides the drilling device to one side of the part, and drills holes on the part through the drilling device. The parts need to be manually placed on the fixed plate for fixation. This processing method is not only dangerous, but also time-consuming and labor-intensive, with low processing accuracy, and increases production costs. It is not suitable for large-scale production, and the existing positioning device is prone to slight loosening or shaking when clamping and positioning the workpiece, and the clamping effect is poor.

The Chinese utility model patent with application number: 201820711776.8 discloses a milling and drilling machine, which includes a feeding device, a milling and drilling machine and a discharging device. The feeding device is divided into a front section and a rear section. The front section includes a first bracket and a first roller. The rear section includes a second bracket, a third bracket, a second roller and a third roller. The milling and drilling machine includes a frame, a milling and drilling workbench, a drilling unit and a milling slot unit.
