Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of metal processing, in particular to a drilling machine tool for processing metal products. Background Art
[0002] Metal drilling machine tools are widely used in many fields such as mechanical manufacturing, aerospace, automobile industry, mold manufacturing, etc. They are essential for manufacturing various parts and components. They are an indispensable practical tool for the development of modern industry. However, there are still many problems in traditional drilling machine tools.
[0003] First of all, it is about cooling. When the drilling rig is working at high speed, the friction between the drill bit and the workpiece will generate a lot of heat. This heat will damage the drill bit and the workpiece, especially for some workpieces with high quality requirements. Therefore, there is a watering method to cool down, but a lot of water will be consumed in this process, which can easily cause a waste of water resources. In addition, the iron filings produced by drilling are also very fine and can easily enter the interior of the machine and cause damage.
[0004] Secondly, regarding the problem of drilling depth, the requirements of many workpieces are different, so the drilling depth is different. The traditional method is to use a cylinder to lift and lower. Although the lifting and lowering of the cylinder is relatively simple, slight rebound will occur during the downward pressure drilling process, which can easily cause depth deviation.
[0005] Finally, there is clamping and fixing. For workpieces with different shapes, the traditional fixed clamping mechanism can only clamp one or two types of workpieces, and it is manually operated, which is laborious and inefficient. Utility Model Content
