Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of machining centers, and in particular relates to a spindle box for a five-axis machining center. Background Art
[0002] Five-axis machining is a mode of CNC machine tool machining. Usually, five-axis linkage refers to the linear interpolation movement of any five coordinates of x, y, z, A, B, and C. Among them, x, y, and z are commonly used 3D coordinate axes, and A, B, and C refer to the rotation axes that rotate around the x, y, and z axes respectively. In other words, five axes refer to the three moving axes of x, y, and z plus any two rotation axes. Compared with the common three-axis machining, five-axis machining refers to the machining of parts with complex geometric shapes, which requires the machining tool to be able to position and connect in five degrees of freedom. The machine tool used for five-axis machining is usually called a five-axis machine tool or a five-axis machining center. The five-axis machine tool can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the machining efficiency of prismatic parts.
[0003] The spindle box is an important part of the machine tool. It is used to arrange the working spindle of the machine tool and its transmission parts and corresponding additional mechanisms. The spindle box is a complex transmission component, including the spindle assembly, reversing mechanism, transmission mechanism, braking device, operating mechanism and lubrication device. Its main function is to support the spindle and make it rotate, and realize the functions of spindle starting, braking, speed change and reversing.
[0004] The existing five-axis machining center spindle box still has the following shortcomings: 1. The existing five-axis machining center devices mostly use fixed drill modules to store drill bits in the design of automatic drill bit replacement. When replacing the drill bit, the Z-axis moving column needs to be moved and adjusted along the X-axis direction so that the drill bit and the drill module are located in the same plane before replacement can begin. This design cannot replace the drill bit at any time, and after moving, it will cause errors in the repositioning of the drill bit.
[0005] 2. The spindle box of the existing five-axis machining center is generally set for the rotation of the drill bit, but the drill bit is generally set as a fixed vertical structure. During the processing of the equipment, the equipment will be processed at multiple angles, and it is necessary to frequently mobilize the movement of other bearings, which will make the processing work more cumbersome.
[0006] 3. The movement of the X, Y and Z axes of the existing five-axis machining center devices is mostly controlled by a single reciprocating screw. When moving or carrying objects, a large weight will cause pressure on the single reciprocating screw, and the single reciprocating screw will also affect the movement speed, stability and firmness during the movement.
