[0027] Reference Figure 1-4 An intelligent processing production line for elevator dynamic and static plates includes a CNC four-sided milling machine 1, a first CNC milling and boring machine 2, and a second CNC milling and boring machine 3. The CNC four-sided milling machine 1 includes a first bed 4, on which a first spindle 5 and a second spindle 10 are installed.

The gear reduction box 11 is installed with the corresponding first spindle 5 or the second spindle 10 through a synchronous belt transmission mechanism 13. The first spindle 5 or the second spindle 10 is installed with a gear reduction box 11. The gear reduction box 11 is installed with the corresponding first spindle 5 or the second spindle 10 through a synchronous belt transmission mechanism 13. The spindle 5 and the second spindle 10 are both equipped with a tool release mechanism 12, and the first spindle 5 and the second spindle 10 are both equipped with a disc milling cutter 19 to mill the periphery of the workpiece; the first CNC milling and boring machine 2 and the second CNC milling and boring machine 3 are both provided with a first spindle box 29 and a second spindle box 30, and the first spindle box 29 and the second spindle box 30 are both equipped with a milling cutter or a slotting cutter 39, and the milling cutter is cooperatively arranged on the first CNC milling and boring machine 2 to mill the upper and lower end surfaces of the workpiece, and the slotting cutter 39 is cooperatively arranged on the second CNC milling and boring machine 3 to slot the workpiece;

[0028] The first bed 4 is provided with an exchange mechanism 6 capable of 180° limited rotation, a first CNC indexing table 16 is provided on the first bed 4, the first CNC indexing table 16 is arranged below the rotation area of ​​the exchange mechanism 6, a second centering clamping mechanism 9 and a first centering clamping mechanism 8 are provided on the exchange mechanism 6 to center and position the workpiece, a workpiece clamping cylinder 17 is provided above the first CNC indexing table 16, the workpiece clamping cylinder 17 moves vertically limited to press the workpiece on the exchange mechanism 6 onto the first CNC indexing table 16, the first CNC indexing table 16 is provided between the first spindle 5 and the second spindle 10, a first workbench 18 is provided on the first bed 4, the first CNC indexing table 16 moves within the upper limit of the first workbench 18, and a material unloading platform 7, an electric control mechanism 14 and a hydraulic system 20 are provided on the first bed 4;

[0029] When this embodiment is used, the workpiece is placed in the first centering clamping mechanism 8, the workpiece is clamped, and then the exchange mechanism 6 rotates 180° to send the workpiece to the fixture of the first CNC indexing table 16. At this time, the workpiece clamping cylinder 17 moves down to press the workpiece on the first CNC indexing table 16, and then the first centering clamping mechanism 8 is released; then the first CNC indexing table 16 moves along the first workbench 18 into the processing area, and at the same time the first spindle 5 and the second spindle 10 move to the cutting position, and the workpiece begins to be milled all around.

[0030] The existing similar equipment clamps the workpiece by directly placing the workpiece on the indexing table. The workpiece alignment adopts the method of fixing one end and pushing against the other end, which cannot realize the centering of the blank, resulting in high requirements for the blank size or inconsistent machining allowances on both sides. The forces on both sides during the machining process are uneven, which easily causes the machining workpiece to be skewed. It is difficult to ensure the machining accuracy in one machining, and it is necessary to perform multiple machining operations to achieve high-precision requirements. The workpiece alignment requires two directions, front and side, two indexing rotations, two loosening and clamping actions, which take up a lot of cutting time and have a low equipment utilization rate. This equipment, while processing, loads and unloads the material on the loading and unloading platform 7 outside the machine, and automatically aligns the workpiece; the centering clamping device is on the loading and unloading platform 7, which automatically aligns the center of the workpiece to ensure uniform machining allowances on both sides. There is no need to align inside the machine, and it can be directly pressed into the machining; it greatly improves the equipment utilization rate and ensures the machining accuracy of the parts.
