Description

Technical Field

[0002] Deep hole drilling machine tools are machine tools specially used in the process of deep hole drilling. They mainly rely on specific drilling technology (such as gun drilling, BTA drilling, ejector drilling, etc.). Special machine tools for drilling deep hole systems and precision shallow holes with an aspect ratio greater than 10 are collectively referred to as deep hole drilling machines.

[0003] Deep hole drilling machines are key equipment for processing deep hole workpieces. At present, most of the deep hole drilling machine workpiece fixtures on the market adopt a fixed design. Although they can meet the clamping needs of workpieces with a single diameter, when facing workpieces with different diameters, the fixtures need to be replaced frequently, and the clamping stability is low, which not only reduces production efficiency, but also increases operation complexity and cost. In addition, a small number of devices that can clamp workpieces of different diameters often need to move the position of the drill to make the workpiece and the axis of the drill consistent when clamping workpieces of different diameters, which increases the operation steps and reduces the processing efficiency;

[0004] With respect to the above-mentioned related technologies, the inventor believes that the workpiece clamp used for deep hole drilling machine tools has the defects of being difficult to stably clamp workpieces of different diameters, and being difficult to keep the position of the axis consistent when clamping workpieces of different diameters;
