Technical Field

[0001] The utility model relates to the technical field of drilling machine tools, in particular to a chip collecting mechanism of a drilling machine tool. Background Art

[0002] Carbon fiber composite material is a two-phase composite material, which is formed by converting organic fiber through a series of heat treatments and is an inorganic high-performance fiber with a carbon content of more than 90%. It has excellent mechanical properties, combines the inherent characteristics of carbon materials and the softness and processability of textile fibers, and belongs to a new generation of reinforcing fibers. The performance of carbon fiber composite materials is higher than that of ordinary carbon in some aspects, and its application range is much wider than that of ordinary carbon.

[0003] Drilling machines are required for drilling carbon fiber composites. The rotation of the drill bit is the main motion for drilling holes in carbon fiber composites, while the axial movement of the drill bit is the feed motion. During the drilling process, the carbon fiber composite material is usually kept fixed, while the tool performs a rotational motion. The working principle of the drilling machine tool includes the bed structure, spindle rotation, workpiece feed, and main drive device. The workpiece is clamped on the workbench, and the main drive device is started to rotate the spindle, and then the feed device is controlled to move the workpiece so that the drill bit contacts the surface of the workpiece and drills along the specified path. During the drilling process, the depth, speed, and accuracy of the drilling can be controlled by adjusting parameters such as the feed device and spindle speed.

[0004] Common drilling machines generate chips during drilling, and the chips need to be collected in a centralized manner. However, the surface of the tool is also prone to chips clinging to it, and the chips clinging to the tool surface have a significant impact on the processing of carbon fiber composite materials. Since the tool surface is uneven, chip cleaning is more difficult, which reduces the processing accuracy. In view of this, the present application proposes a chip collection mechanism for a drilling machine tool. Utility Model Content

[0010] Furthermore, a drilling platform is fixedly installed on the top of the machine tool, and sliding grooves are fixedly installed on the tops of two sides of the machine tool that are located away from the drilling platform.

[0011] Furthermore, the inner side walls of the two sliding grooves are slidably mounted with collecting sliders, the inner side walls of the sliding grooves are rotatably mounted with collecting screws, and the collecting sliders and the collecting screws are threadedly connected.
