[0029] In this embodiment, the movable frame 1 is moved to the middle of three CNC machine tools 200, with turning and milling CNC machine tools 200 placed on both sides and a drilling and tapping CNC machine tool 200 placed at one end. During processing, the six-axis manipulator 300 is controlled by the PLC control box to place the semi-finished product processed by one of the turning and milling CNC machine tools 200 on the transfer table 3 for waiting. The six-axis manipulator 300 moves the semi-finished product on the transfer table 3 to the drilling and tapping CNC machine tool 200 for processing. Then, when drilling and tapping, the six-axis manipulator 300 moves to another turning and milling CNC machine tool 200 to move the semi-finished workpiece to the transfer table 3. At this time, after drilling and tapping are completed, the six-axis manipulator 300 grabs the finished product and moves it to the cleaning mechanism 4. After the debris on the surface of the finished product is cleaned by the cleaning mechanism 4, the cleaned finished product is finally moved to the finished product storage mechanism 2 for storage, thereby completing the entire processing process, and finally repeating the above steps.

[0030] The finished product storage mechanism 2 includes a mounting groove 21, and two linear motion modules are arranged in the mounting groove 21. The two linear motion modules are respectively connected to a bracket 25 by transmission. A finished product storage tray 26 is placed on the surface of the bracket 25, and the two finished product storage trays 26 are arranged alternately up and down. The finished product storage mechanism 2 includes two groups of finished product storage trays 26 that are staggered up and down, and the bottoms are driven by linear motion modules. During use, one of the finished product storage trays 26 can be driven by the linear motion module to move to one end close to the six-axis manipulator 300, and the other finished product storage tray 26 is at the other end. After one of the finished product storage trays 26 is full, the two finished product storage trays 26 can be driven to change positions by two linear motion modules. Employees can take away the full finished product storage tray 26 and replace it with an empty tray.

[0031] Specifically, the linear motion module includes two parallel guide rails 22 and a rodless cylinder 24, the surface of the guide rail 22 is slidably connected with a slider 23, the surface of the slider 23 is fixedly connected to the bottom of the bracket 25, and the rodless cylinder 24 is in transmission connection with the bracket 25. In this embodiment, the rodless cylinder 24 adopts the AirTac rodless cylinder 24, model RMS20X500, and the bracket 25 is driven by the rodless cylinder 24 to move, the guide rail 22 and the slider 23 play a role of support and auxiliary movement, and the two different brackets 25 have different heights, so that the two finished product storage trays 26 can move up and down alternately without colliding with each other.

[0032] Specifically, the transfer table 3 includes a transfer plate 31, on which a plurality of placement slots 32 are evenly distributed, and a shielding plate 33 is provided around one side of the transfer plate 31 close to the six-axis manipulator 300. By providing a plurality of evenly distributed placement slots 32 on the transfer plate 31, semi-finished products are placed to achieve transfer operations. The shielding plate 33 is surrounded by the edge to shield debris when blowing to prevent it from being blown into the rack.

[0033] Specifically, the cleaning mechanism 4 includes a cleaning groove 41, a mounting plate 42 is fixedly connected with bolts in the cleaning groove 41, a blowing head 43 and a blowing pipe 44 are fixedly connected to the mounting plate 42, the blowing head 43 and the input end of the blowing pipe 44 are connected with a blowing device, a collecting port is provided at the bottom of the cleaning groove 41, a chip removal pipe 45 is connected to the collecting port, and a waste bucket 46 is provided at the bottom of the chip removal pipe 45. During the cleaning process, the six-axis manipulator 300 first moves the finished product to the front of the blowing head 43, blows the debris on the surface of the workpiece into the cleaning groove 41 through the strong wind blown by the blowing head 43, and then transfers it to the position of the blowing pipe 44, moves the workpiece, and inserts the blowing pipe 44 into the workpiece for blowing, so as to clean the internal debris, and the blown debris falls into the cleaning groove 41, enters the chip removal pipe 45 from the middle collecting port, and finally falls into the waste bucket 46 for collection.

[0034] Specifically, the fixture assembly includes a fixed plate 51, one end of which is connected to the six-axis manipulator 300, a finger cylinder 52 is fixedly connected to the bottom of the fixed plate 51, and a clamping plate 53 is fixedly connected to the output shaft of the finger cylinder 52. The six-axis manipulator 300 drives the fixture assembly to move to the side of the workpiece through the bolt connection between the fixed plate 51 and the six-axis manipulator 300, and drives the clamping plate 53 to clamp the workpiece and move it through the finger cylinder 52.

[0035] Furthermore, the surface of the fixing plate 51 is fixedly connected with a mounting block 54 by bolts, and the mounting block 54 is fixedly connected with an air blowing pipe 55, and one end of the air blowing pipe 55 is connected with an air blowing device. The workpiece clamped by the clamp assembly is blown by the air blowing pipe 55, so as to clean the debris on the surface of the workpiece, and when moving to the turntable 3, the turntable 3 is first blown by the air blowing pipe 55 to blow away the debris remaining on the turntable 3, so as to avoid the workpiece being repeatedly contaminated by the debris, and further improve the cleaning effect.

[0036] Specifically, it also includes a protective bracket 61, which is fixedly connected to the middle of the movable frame 1, and the two sides of the top of the protective bracket 61 are respectively hinged with protective plates 62. When working, the protective plate 62 is rotated to be unfolded, which means that work is in progress. The staff cannot work across the protective plate 62, which plays a protective role, and the two finished product storage trays 26 can move under the protective plate 62. After storage is completed, they move to the side of the protective plate 62 away from the six-axis manipulator 300. At this time, the staff can take it away, and the protective plate 62 provides protection to improve safety.

[0037] Further, the bottom of the movable rack 1 is fixedly connected with a plurality of casters and adjustable feet 101. The movable rack 1 can be moved by the casters, and after being moved to a suitable position, it is fixed by the adjustable feet 101, and the rack is parked more stably.

[0038] Furthermore, a handrail 102 is fixedly connected to the side of the movable frame 1. The handrail 102 is used to push the device to move to a specified position, which is convenient for movement and control.

[0039] The working principle of the present invention is as follows: the movable frame 1 is moved to the middle of three CNC machine tools 200, with turning and milling CNC machine tools 200 placed on both sides and a drilling and tapping CNC machine tool 200 placed at one end. During processing, the six-axis manipulator 300 is controlled by the PLC control box to place the semi-finished product processed by one of the turning and milling CNC machine tools 200 on the transfer table 3 for waiting. During the movement, the air blowing pipe 55 is used to blow air to the workpiece and the transfer table 3 to blow off the remaining debris, thereby improving the subsequent processing accuracy. The six-axis manipulator 300 moves the semi-finished product on the transfer table 3 to the drilling and tapping CNC machine tool 200 for processing. Then, when drilling and tapping, the six-axis manipulator 300 moves to another turning and milling CNC machine tool 200 to move the semi-finished workpiece to the transfer table 3. At this time, after the drilling and tapping are completed, the six-axis manipulator 300 grabs the finished product and moves it to the cleaning mechanism 4. During the cleaning process, the six-axis robot 300 first moves the finished product to the front of the blowing head 43, and uses the strong wind blown by the blowing head 43 to blow the debris on the surface of the workpiece into the cleaning groove 41, and then transfers it to the position of the blowing pipe 44, moves the workpiece, and inserts the blowing pipe 44 into the interior of the workpiece for blowing, so as to clean up the internal debris, and the blown debris falls into the cleaning groove 41, enters the chip discharge pipe 45 from the middle collection port, and finally falls into the waste bucket 46 for collection. After the debris on the surface of the finished product is cleaned by the cleaning mechanism 4, the cleaned finished product is finally moved to the finished product storage mechanism 2 for storage, thereby completing the entire processing process, and finally repeating the above steps.
