Detailed ways

The present invention will be described in detail below with reference to the drawings and specific embodiments.

As shown in FIG. 1-3, the invention provides an intelligent grinding machine tool comprising a base 1, a column 2, a combined power head 3, a workpiece rotation device 4, a workpiece exchange device 5, a flexible clamping device 6, a slide table 7 and The tool magazine 8, wherein the base 1 adopts an inverted "T" type structure, the column 2 is disposed at the rear of the base 1, and the combined power head 3 is mounted on the column 2, and the column 2 can be moved back and forth on the base 1 to realize Z-axis movement; The power head 3 can be moved up and down on the column 2 to realize the Y-axis movement; the front portion of the base 1 is provided with a slide table 7, and the workpiece rotation device 4, the workpiece exchange device 5, the flexible clamping device 6, and the tool magazine 8 are mounted on the slide table 7. The slide table 7 can be moved left and right on the base 1 to realize X-axis movement.

The invention breaks the structure of the machine tool XYZ three-coordinate structure and the power head placed on one side, adopts the new layout to shift the X-direction of the long stroke to the workpiece side, and places the Z-direction and the Y-direction of the short stroke on the power head side. The X axis, Y axis, and Z axis are all driven by a servo motor and a ball screw. The above three-way composite realizes the relative movement of the tool to the workpiece X, Y and Z. The advantage of this layout is that a. moving out of the X-axis causes the three-way motion on the power head side to become two-way motion, and the height of the whole machine is lowered; b. The column 2 only performs the short-stroke Y-axis motion compared to the short-stroke Y. The X-axis movement of the shaft movement and the long stroke is more stable; the space on both sides is vacated for the electric cabinet and the pneumatic cabinet, and the structure is more compact. c. The total mass of the workpiece rotating device 4 and the flexible clamping device 6 and the workpiece on the workpiece side is much smaller than the total mass of the tool-side column 2 and the highly flexible combined power head 3 and the tool. Therefore, the X-axis servo motor and drive module are reduced, and the machine tool consumes less energy.

The dual output spindle 305 can be used to mount two tools at the same time, and can realize C axis motion by 180° rotation and arbitrary angle positioning. The tool can be deflected at any angle to solve the problem that the fixed position tool does not grind the workpiece with a spatial angle. The auxiliary spindle 306 is equipped with a tool that can be moved back and forth and stopped at any position to achieve W-axis motion. The movable tool solves the problem that the fixed position tool cannot avoid the clamp, which causes the double output spindle to not enter the cutter arbitrarily.

The workpiece exchange device 5 is lowered to engage the workpiece system with the workpiece rotation device 4, and the tip assembly 600 on the clamp device 6 is dropped to clamp the workpiece. The laser detecting device 9 performs optical detection on the workpiece to be processed, performs calculation after the detection is completed, and transmits the calculation result to the main control system, and the CNC system performs compensation adjustment of the workpiece position and the dimensional deviation. When the workpiece is more complicated, the auxiliary spindle 306 on the combined power head 3 needs to be replaced with a different tool, and the auxiliary spindle 306 is changed to the tool magazine 8 according to the numerical control program.

During the processing, when the safety grating 10 detects any object or person in the safe area, the machining continues, but the workpiece exchange device 5 does not rotate after the machining. Only when the safety grating 10 detects that there is no object or person in the safe area, the workpiece exchange device 5 rotates and enters the loop processing. When the workpiece exchange device rotates 180° during the workpiece exchange process, when any object or person enters the safety area of the safety grating 10, the rotation action will immediately stop, avoiding the damage of the swing arm and the workpiece in the exchange.

The above description is only an embodiment of the present invention, and is not intended to limit the scope of the present invention.
