[0039] The working principle of the present invention is:

[0040] When the first position adjustment component is working: the output shaft of motor four 403 drives screw two 404 to rotate, and when screw two 404 rotates, it drives position adjustment frame one 401 to slide on slide rail one 402 through slider one, and slide rail one 402 drives waste chip collection component, rotating component and telescopic clamping component to move in left and right directions through the second position adjustment component.

[0041] When the second position adjustment component is working: the output shaft of motor five 502 drives screw three 503 to rotate, and when screw three 503 rotates, it drives position adjustment frame two 501 to move on position adjustment frame one 401 through slider two, and position adjustment frame two 501 drives slide seat two 504 to move on slide rail two 405, and position adjustment frame two 501 drives the waste chip collection component, the rotating component and the telescopic clamping component to move in the front and rear directions.

[0042] The telescopic clamping assembly is moved to the loading area for loading by the first position adjustment assembly and the second position adjustment assembly.

[0043] When the telescopic clamping assembly is working: the third suction device enables the pneumatic clamping jaw 801 to work through the suction pipe three, and the pneumatic clamping jaw 801 drives the two clamping heads 802 to move closer to or away from each other, and the workpiece is clamped by the two clamping heads 802. Since the clamping heads 802 are provided with anti-slip strips, the workpiece can be clamped to prevent the workpiece from being displaced and causing deviations during the drilling or tapping process; when it is necessary to adjust the distance between the two telescopic clamping assemblies, the piston rod of the electric cylinder three 803 drives the pneumatic clamping jaw 801 to move, and at the same time the spline shaft 804 slides in the rotating drum 603, thereby adjusting the distance between the two telescopic clamping assemblies, and then workpieces of different sizes can be clamped. After clamping is completed, the first position adjustment assembly and the second position adjustment assembly are moved to the position of the tapping assembly through the telescopic clamping assembly.

[0044] When the rotating assembly is working: the output shaft of the motor 602 drives the drum 603 to rotate, and when the drum 603 rotates, it drives the support plate 2 604 and the spline shaft 804 to rotate, and the support plate 2 604 and the spline shaft 804 drive the telescopic clamping assembly to rotate; Figure 1 and Figure 2 As shown, the rotating component can drive the telescopic clamping component to adjust to different postures. Since the telescopic clamping component can be driven to move by the first position adjustment component and the second position adjustment component, and the telescopic clamping component itself can be telescoped, it can meet the clamping needs of various workpieces, thereby improving the application scope of workpiece clamping. At the same time, the position of the workpiece can be rotated to meet the processing needs of different workpieces.

[0045] When the lifting assembly and the tapping assembly are working: the required tap or drill bit is taken out from the first tool magazine and loaded into the pneumatic chuck 208 through the first tool changing mechanism, and the pneumatic chuck 208 is used to clamp or release the tap or drill bit through the second suction device and the suction pipe 2; the output shaft of the motor 204 drives the screw 202 to rotate, and when the screw 202 rotates, it drives the slide 205 to slide on the track groove 203, and the slide 205 drives the tapping assembly to move in the up and down directions, and the output shaft of the motor 207 drives the pneumatic chuck 208 to rotate, and the pneumatic chuck 208 drives the tap or drill bit to rotate, so that the tap or drill bit rotates and moves at the same time, and then drills or taps the workpiece; during the processing, the first position adjustment assembly and the second position adjustment assembly are driven to move the rotating assembly and the telescopic clamping assembly, and then the position of the workpiece is adjusted, so that different positions of the workpiece can be processed, thereby increasing the processing range of the workpiece.

[0046] When the detection component is working: after the processing is completed, the first position adjustment component and the second position adjustment component drive the rotating component and the telescopic clamping component to move, and then drive the processed workpiece to move to the position of the detection component, and the required detection bolts are taken out from the second tool magazine and loaded into the pneumatic chuck 2 312 through the second tool changing mechanism, and the pneumatic chuck 2 312 clamps or loosens the detection bolts through the first suction device and the suction pipe 3; the piston rod of the electric cylinder 2 305 drives the connecting frame 303 to move, and the connecting frame 303 drives the guide rod 308 to move in the slide groove 1 302, and drives the electric cylinder 1 304 to move in the slide groove 2 307, and the guide rod 308 is supported Plate 1 309 drives motor 311 and pneumatic chuck 2 312 to move to the required position, and the piston rod of electric cylinder 1 304 pushes support plate 1 309 to move on guide rod 308, and at the same time, the output shaft of motor 311 drives the detection bolt to rotate through pneumatic chuck 2 312, so that the detection bolt can move while rotating, and move the detection bolt to the corresponding threaded hole on the workpiece, and the thread detection device connected to pneumatic chuck 2 312 can provide real-time feedback on whether the threaded hole processing is qualified; if unqualified, the parameters and processing process are adjusted in time to avoid mass-produced unqualified products, thereby ensuring the quality of the workpiece tapping processing and improving the product yield.

[0047] When the waste chip collection component is working: waste chips are generated during the tapping or drilling process of the workpiece, and the waste chips fall into the waste chip collection chamber of the position adjustment frame 501 under the action of water spraying from the water spraying device, and the larger waste chips are filtered through the multiple filter slots 702 on the waste chip collection frame 701, and the small-sized waste chips, waste chip foam and waste water enter the storage chamber in the waste chip collection frame 701 through the filter slot 702, and the waste chip foam and waste water enter the discharge channel 707 through the filter slot 706, and enter the water absorption device 2 through the discharge pipe 507 for collection, and a part of the large-sized waste chips and waste water are sucked into the water absorption device 1 through the discharge pipe 506 for collection, and the small-sized waste chips that cannot pass through the filter slot 706 and a part of the large-sized waste chips are left on the waste chip collection frame 7 01 and on the waste chip collection rack 701. After the processing is completed, the waste chip collection assembly is moved to the falling area through the first position adjustment assembly and the second position adjustment assembly, and the baffle 1 703 is pushed open. At the same time, the waste chip collection rack 701 and the baffle 2 704 are pulled out from the position adjustment rack 2 501 through the handle 708, and then the baffle 2 704 is moved out of the waste chip collection rack 701 by pulling the groove 705, so as to facilitate the cleaning of the waste chips in the storage cavity of the waste chip collection rack 701 and on the waste chip collection rack 701, thereby greatly improving the convenience of cleaning and collecting waste chips and wastewater through the waste chip collection device, reducing the cleaning time and cleaning workload in the machining center after each processing, greatly improving the cleaning efficiency, and facilitating the classification and collection of waste chips of different sizes.

[0048] It should be particularly noted that the start and stop of the power parts, the control of air intake and the overall working process of the present invention are all controlled by programming of the program control unit.
