Description
Technical Field
[0001] The utility model relates to the technical field of ultra-high pressure water jet cutting machine installation, in particular to an AB axis water jet cutting head with adjustable precision. Background Art
[0002] Ultra-high pressure water jet cutting machine is a very important industrial processing equipment. It can cold cut various materials by adding abrasives through ultra-high pressure water flow. With the continuous development of science and technology, ultra-high pressure water jet cutting machines are also constantly upgraded. Among them, the most important is the five-axis ultra-high pressure water jet cutting machine. At present, there are two main five-axis control systems and cutter head structures on the market: AC and AB.
[0003] AC five-axis means that the A-axis rotates around the X-axis of the machine tool, and the C-axis rotates around the Z-axis. AB five-axis means that the A-axis rotates around the X-axis of the machine tool, and the B-axis rotates around the Y-axis of the machine tool. The existing AB five-axis cutting head does not have an adjustment mechanism on the A and B axes, that is, the space between the cutter head seat and the B axis, and between the B axis and the A axis are not adjustable. The AB cutter head has a theoretical intersection point in design, and the CNC system controls this theoretical point to achieve cutting. Since errors and deformations are inevitable in the actual processing and production of spare parts, the theoretical intersection point and the actual control point will be misaligned, that is, the actual control point of the cutter head will deviate, which will result in poor precision or even deformation of the cut product.
[0004] Therefore, an AB-axis water jet cutting head with adjustable precision is developed based on achieving high-precision water jet cutting to solve the above technical problems. Utility Model Content
