Numerical control machining tool and rotary work platform thereof

Abstract

The invention discloses a numerical control machining tool and a rotary work platform thereof. The Numerical control machining tool comprises a chassis, a main shaft device, a translation device and the rotary work platform, wherein the main shaft device is connected with the chassis through the translation device, the translation device is used for driving the main shaft device to translate along an axis X, an axis Y and an axis Z, the axis X, the axis Y and the axis Z are perpendicular to each other, and the rotary work platform is fixed on the chassis. The rotary work platform comprises a clamp component used for clamping workpieces, an axis A component, an axis B component and an axis C component, wherein the rotary work platform is capable of driving the workpieces to rotate around an axis A , an axis B and an axis C. Positional angles of cutters and the workpieces can be adjusted at any time, so that the numerical control machining tool is enabled to be provided with flexibility and softness, a best cutting point can be fully used for carrying out cutting. High-efficiency high-quality machining of products which are provided with diversity, the flexibility and complex shape is guaranteed, meanwhile, clamping the workpieces at one time is achieved, that is the numerical control machining tool is capable of finishing combined machining of the products accurately.

Description

technical field [0001] The invention relates to the technical field of numerical control machining, in particular to a numerical control machining machine tool and a rotary worktable thereof. Background technique [0002] With the continuous development of my country's CNC machining industry, the processing requirements are also constantly improving. Three-axis CNC machining has many deficiencies in meeting the requirements of product shape complexity, high precision in shape and position, and short processing cycle. The multi-axis CNC machine tool can just make up for these shortcomings. One clamping can complete the processing of multiple surfaces, simplify the process of tool setting and clamping, reduce the resulting errors, and improve processing efficiency. It can process complex-shaped curved surfaces that three-axis machining centers cannot complete. Therefore, a five-axis machining center has appeared, such as the XTK138 / 5 five-axis CNC machine tool produced by a ...

Three-axis CNC machining has many shortcomings in meeting the requirements of product shape complexity, high precision in shape and position, and short processing cycle.

Therefore, a five-axis machining center has appeared, such as the XTK138 / 5 five-axis CNC machine tool produced by a certain company, which is mainly composed of a bed, a cross slide, a ram, a column, an AC linkage milling head, an automatic oil supply system, a cooling system and a CNC system. The cross slide installed on the bed drives the table to move along the X and Y axes, the ram installed on the column drives the A and C-axis linkage milling head to move along the Z axis, and the milling cutter rotates around the X axis. , Z-axis swing and rotate, thus forming a five-axis motion system with three linear axes and two rotary axes, however, the workpiece on this system can only do linear motion

There is also a workbench of a machine tool, which can drive the workpiece to rotate around the vertical axis. The above two machine tools are difficult to guarantee high-efficiency and high-quality processing of products with diverse, flexible and complex shapes; For products that need to be processed on each surface, the workpiece needs to be removed during processing to process different surfaces. It is difficult to complete all the turning, batching, carving, and engraving composite processing of the product with high precision by clamping the workpiece at one time.
