Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a moving beam type five-axis machining center. Background Art

[0002] The moving beam five-axis machining center is an advanced CNC machine tool with the ability to move five independent axes, including three linear axes of X, Y, and Z and two rotary axes of A and C (or B axis, depending on the machine design). This machine tool uses a precise control system and advanced motion control algorithms to complete the processing of complex surfaces in a single clamping, thereby improving processing efficiency and accuracy.

[0003] At present, the structure of the moving beam type five-axis machining center includes a base, a column, a crane, a middle support plate and a spindle box. The column is equipped with a Y-axis motor screw submodule for driving the crane to move. As a result, under the same stroke conditions, the front and rear lengths of the base and the column are increased and the space occupied is increased, which increases the material cost. In addition, the Y-axis screw nut seat is thin, the force distribution is uneven, the strength is not high, and it is easy to break, causing safety risks. The middle support plate is equipped with a Z-axis motor screw submodule for driving the spindle box to move. Under the same stroke conditions, the height of the middle support plate is greatly increased, which increases the material cost and causes transportation problems. The increase in kinetic inertia leads to a decrease in mechanical motion performance. The wiring of the Y-axis, X-axis and Z-axis motor screw sub-modules (cables and water, gas and oil pipes) requires three sets of drag chains, which makes the circuit, gas and oil pipelines too long, increasing costs, making threading and assembly difficult, and increasing labor and time costs. The front end of the base is flush or protruding, occupying the position for clamping the workpiece, making it inconvenient for manual clamping (excessive reaching and bending), and it is difficult to plan and install the left outer shield sheet metal (shell). Therefore, it is necessary to design a moving beam five-axis machining center to improve the above problems. Utility Model Content
