[0016] Example 2 Furthermore, the intelligent manufacturing and repair unit specifically includes a clamping and positioning system 1, a clamping and positioning system 2, and an automatic nail extraction device 3. Among them, the clamping and positioning system 1 includes a rotatable basic tooling 1-4, and a claw 1-3 on the basic tooling 1-4 is used to limit and fix the nail to be processed (the nail on the workpiece limited on the basic tooling 1-4); the automatic punching and tapping device 2 includes a movably set tapping mounting seat, and the tapping mounting seat is arranged on one side of the basic tooling 1-4; a punching spindle 2-2 for punching holes for the nail, a tapping spindle 2-3 for tapping the nail, and an automatic thread locking machine 2-3 for tightening the nail are arranged on the side of the tapping mounting seat close to the basic tooling 1-4; the automatic nail extraction device 3 includes a nail clamping groove 3-4, and the nail clamping groove 3-4 is movably set on one side of the basic tooling 1-4, and is used to limit the nail on the basic tooling 1-4 and rotated to the position of the nail clamping groove 3-4 after processing.

[0017] In an embodiment, Figure 2As shown, by placing the nail to be processed in the basic tooling 1-4 of the clamping and positioning system 1, a plurality of claws 1-3 are respectively arranged around the basic tooling 1-4, and the claws 1-3 are detachably connected to the top of the clamping support frame 1-1 by bolts; the basic tooling 1-4 is stabilized on the clamping support frame 1-1 by limiting the position of the claws 1-3, and the claws 1-3 are detachably connected to the clamping support frame 1-1 by bolts; in this way, basic tooling 1-4 with different limiting positions can be realized, and different basic tooling 1-4 can be compatible with different secondary toolings, and the tooling accuracy is used to ensure the installation accuracy of the workpiece (the workpiece in this embodiment is a nail); at the same time, an airbag damper is placed inside the workpiece to support the inside of the workpiece to avoid damage to the workpiece during the clamping process and processing.

[0018] At the same time, a clamping support frame 1-1 is provided at the bottom end of the basic tooling 1-4, and the basic tooling 1-4 is rotatably installed and connected to the top of the clamping support frame 1-1 through a turntable 1-2, and the clamping support frame 1-1 is used for ground anchoring. In order to drive the rotating basic tooling 1-4, the turntable 1-2 at the bottom of the basic tooling 1-4 is connected with a rotating large gear (the rotating large gear and the turntable 1-2 are detachably connected by bolts, which is convenient for replacing different basic tooling 1-4), and the rotating large gear is meshed with a driving pinion, which is connected to the output end of the servo motor through a rotating shaft, and the servo motor is used to be installed and fixed on the clamping support frame 1-1.

[0019] When it is necessary to adjust the small nail placed on the basic tooling 1-4 and to perform processing, the driving small gear is driven to rotate by the servo motor of the clamping support frame 1-1, and the driving small gear drives the rotating large gear meshing with it to rotate. Since the rotating large gear is connected to the basic tooling 1-4, the basic tooling 1-4 is driven by the basic tooling 1-4 to rotate under the action of the limiting guide of the set claw 1-3, and the small nail fixed by the upper limit of the basic tooling 1-4 is rotated and moved to the set automatic punching and tapping device 2, and the small nail is processed by the automatic punching and tapping device 2.

[0020] Example 3 like Figure 3 As shown, the automatic drilling and tapping device 2 includes a movably arranged tapping mounting seat, which is arranged on one side of the basic tooling 1-4; a punching spindle 2-2 for drilling holes for nails, a tapping spindle 2-3 for tapping nails, and an automatic thread locking machine 2-3 for tightening the nails are arranged on the side of the tapping mounting seat close to the basic tooling 1-4.

[0021] At the same time, a tapping support frame 2-1 is arranged at the bottom end of the tapping mounting seat, and the tapping mounting seat and the tapping support frame 2-1 are movably arranged, and the tapping support frame 2-1 is used for anchoring with the ground; the tapping mounting seat is movably installed and connected to the tapping support frame 2-1, so as to facilitate the adjustment of the tapping mounting seat, thereby facilitating the punching spindle 2-2, the tapping spindle 2-3 and the automatic thread locking machine 2-3 arranged on the tapping mounting seat to process the nails on the basic tooling 1-4.

[0022] A tapping lateral servo system 2-6 (an existing electrically-controlled servo motor drive system) is provided at the top end of the tapping support frame 2-1 for driving the tapping mounting seat to move horizontally along the lateral direction of the tapping support frame. The tapping lateral servo system 2-6 is installed and connected to the top end surface of the tapping support frame; a tapping longitudinal servo system 2-7 (an existing electrically-controlled servo motor drive system) is also provided at the top end of the tapping support frame 2-1 for driving the tapping mounting seat to move horizontally along the longitudinal direction of the tapping support frame. The tapping longitudinal servo system 2-7 is installed and connected to the top end surface of the tapping support frame 2-1; a tapping vertical servo system 2-8 (an existing electrically-controlled servo motor drive system) is provided at the top end of the tapping mounting seat 2-1 for driving the tapping mounting seat to move up and down. The tapping mounting seat is set to move up and down with the tapping support frame through the tapping vertical servo system 2-8.

[0023] In the embodiment, through the tapping lateral servo system 2-6, the tapping longitudinal servo system 2-7, and the tapping vertical servo system 2-8, it is possible to drive the tapping mounting seat to move freely in space, that is, on the "X, Y, Z" axes of the coordinate space; by adjusting the tapping mounting seat, the punching spindle 2-2, the tapping spindle 2-3, and the automatic thread locking machine 2-3 on the tapping mounting seat can be adjusted to perform precise processing on the pins on the basic tooling 1-4.

[0024] Furthermore, a visual system 2-5 (existing 3D visual control system) is installed on one side of the tapping mounting seat close to the basic tooling. When the basic tooling 1-4 is adjusted and rotated to drive the pins to be processed on the basic tooling 1-4 to rotate and move to the tapping mounting seat position of the automatic punching and tapping device; at this time, the visual system 2-5 recognizes the characteristic surface position of the pins to be processed on the basic tooling 1-4, and controls the tapping lateral servo system 2-6, tapping longitudinal servo system 2-7, and tapping vertical servo system 2-8 through the control system to adjust the position of the tapping mounting seat, and then the pins on the basic tooling 1-4 are accurately processed through the punching spindle 2-2, tapping spindle 2-3, and automatic thread locking machine 2-3 installed in sequence on the tapping mounting seat.

[0025] It should be noted here that: 1) The visual system 2-5 on the automatic punching and tapping device 2 recognizes the position of the slightly nailed feature surface of the workpiece; 2) Through position recognition, the deviation angle is transmitted to the control system of the basic tooling 1-4 to complete the compensation so that the pin is in the position to be processed; 3) The automatic punching and tapping device 2 adjusts the punching spindle 2-2 to the processing position to complete the thread bottom hole processing; the punching spindle 2-2 is installed with an automatic punching adjustment device at one end close to the nail, that is, the punching adjustment device is an existing punching device for punching the nail; 4) The automatic punching and tapping device 2 adjusts the tapping spindle 2-3 to the processing position to complete the thread tapping; the tapping spindle 2-3 is installed with an automated tapping device at one end close to the nail, that is, the automated tapping device is an existing tapping device, which is used to perform thread tapping on the nail; 5) The automatic punching and tapping device 2 adjusts the automatic thread locking machine 2-4 to the processing position to complete the tightening operation of the nail; the end of the tapping spindle 2-3 close to the nail is equipped with an automatic nail tightening device, that is, the automatic nail tightening device is an existing nail tightening device, which is used to automatically tighten the nail; Furthermore, the above-mentioned visual system 2-5, punching spindle 2-2, tapping spindle 2-3, automatic thread locking machine 2-4 and other device structures can be realized by the existing technology, so in the specific embodiment, there is no further detailed description of the structure of these devices.

[0026] In summary, the visual system 2-5 on the automatic drilling and tapping device 2 identifies the position of the pin feature surface of the workpiece, and feeds back to the control system of the basic tooling 1-4 of the clamping and positioning system 1, and controls the basic tooling 1-4 to complete position compensation, so that the pin is in the position to be processed; then the position of the tapping mounting seat is adjusted in turn through the tapping lateral servo system 2-6, the tapping longitudinal servo system 2-7 and the tapping vertical servo system 2-8, so as to realize the position adjustment of the punching spindle 2-2, the tapping spindle 2-3 and the automatic thread locking machine 2-4 on the tapping mounting seat, and control and adjust the drilling spindle 2-2, the tapping spindle 2-3 and the automatic thread locking machine 2-4 to the position to be processed, and complete a series of tasks such as pin drilling, tapping and pin locking respectively.

[0027] Example 4 like Figure 4As shown, the automatic nail extraction device 3 includes a nail clamping groove 3-4, which is movably arranged on one side of the basic tooling 1-4 and is used to limit the position of the nail on the basic tooling 1-4 and rotated to the position of the nail clamping groove 3-4 after processing. That is, after the processing is completed at the position of the automatic punching and tapping device 2, the clamping and positioning system 1 is adjusted and controlled to clamp and limit the nail on the basic tooling 1-4 after the processing is completed, and the nail on the basic tooling 1-4 after the processing is completed is pulled out from the workpiece on the basic tooling 1-4.

[0028] At the same time, the slightly nailed slot 3-4 is movably installed and connected to the movable control seat through a movable mechanism, and the movable control seat is anchored to the ground through the movable support frame 3-1. In order to control the activity of the movable control seat and facilitate the control of the slightly nailed slot 3-4 to limit the clamping of the slightly nailed pin on the basic tooling 1-4, the top of the movable support frame 3-1 is provided with an active horizontal service system 3-2 (existing electrically controlled servo motor drive system) for driving the movable control seat to move horizontally along the movable support frame, and the active horizontal service system is installed and connected to the top surface of the movable support frame 3-1; the top of the movable support frame 3-1 is also provided with an active vertical servo system 3-5 (existing electrically controlled servo motor drive system) for driving the movable control seat to move horizontally along the movable support frame, and the active vertical servo system 3-5 is installed and connected to the top surface of the movable support frame 3-1.

[0029] Through the movable horizontal servo system 3-2 and the movable vertical servo system 3-5, it is possible to drive the movable control seat to move freely in space, that is, on the "X, Z" axis of the coordinate space; by adjusting the movable control seat, the pin slot 3-4 on the movable control seat can be adjusted to a suitable position, and then the pin that has been upper-limited and processed by the basic tooling 1-4 can be clamped and limited by adjusting the pin slot 3-4; then, by adjusting the pin slot 3-4, the pin that has been upper-limited and processed by the basic tooling 1-4 can be pulled out from the workpiece that has been upper-limited by the basic tooling 1-4.

[0030] Furthermore, the end of the pin slot 3-4 near the movable control seat is provided with a pin slot cylinder 3-5 for driving the pin slot 3-4 to clamp the limited pin, and the pin slot cylinder 3-5 (output rod end) is installed and connected to the pin slot seat, and the pin slot seat and the movable control seat are movably arranged. At the same time, the end of the pin slot seat near the movable control seat is provided with a hydraulic cylinder 3-6, and the pin slot seat and the movable control seat are flexibly arranged through the hydraulic cylinder 3-6 (the output rod end is connected to the pin slot seat, and the pin slot seat is driven to move telescopically through the hydraulic cylinder 3-6).

[0031] In the embodiment, by adjusting the hydraulic cylinder 3-6 to drive the slightly nail card slot seat to telescopically move, and by adjusting the slightly nail card slot cylinder 3-5 to drive the slightly nail card slot 3-4 to move, the slightly nail that has been upper-limited to the basic tooling 1-4 and processed is accurately clamped and limited; then, by controlling the hydraulic cylinder 3-6 to drive the slightly nail card slot seat to contract, the slightly nail is pulled out from the workpiece that has been upper-limited to the basic tooling 1-4.

[0032] In summary, through the above operations: 1) The hydraulic cylinder 3-6 and the screw slot cylinder 3-5 extend simultaneously to open the screw slot 3-4; 2) Move the screw slot 3-4 to the specified position through the horizontal servo system 3-2 and the vertical servo system 3-3; 3) The screw clamping cylinder 3-5 retracts, and the screw clamping groove 3-4 clamps the screw on the workpiece pin; 4) The hydraulic cylinder 3-6 retracts to pull the pin out of the workpiece.

[0033] It should be noted here that the slightly nailed card slot 3-4 is used to be installed and connected to the slightly nailed card slot cylinder 3-5, and the slightly nailed card slot cylinder 3-5 drives the slightly nailed card slot 3-4 to realize the function of "clamping and limiting", thereby clamping and limiting the slightly nailed card slot.
