The first gear 424 is meshed with the second gear 431. The calibration mechanism 5 is provided in the inner groove 411.

[0041] The workpiece to be processed is placed on the calibration mechanism 5, and then the second motor 43 drives the second gear 431 to rotate, and the second gear 431 drives the first gear 424 to rotate, and the first gear 424 drives the second rotating shaft 423 to rotate synchronously, and the second rotating shaft 423 drives the synchronous disk 42 to rotate synchronously, and the synchronous disk 42 drives the volute rolling slide 421 to rotate synchronously, and the four sliders 422 on the volute rolling slide 421 slide on it, and the slider 422 moves toward the calibration mechanism 5 in the first slide groove 412, and the abutment assembly 44 moves synchronously with the slider 422, and the abutment assembly 44 gradually approaches the flange of the workpiece to be processed, and then the four abutment assemblies 44 abut and clamp the flange.

[0042] The abutment assembly 44 includes a horizontal abutment cylinder 441 and a vertical abutment cylinder 442. A first piston 4411 is slidably provided in the horizontal abutment cylinder 441. A first telescopic rod 4412 is provided at the head end of the first piston 4411. A first abutment block 4413 is provided at the head end of the horizontal abutment cylinder 441.

[0043] The horizontal abutment cylinder 441 can move with the slider 422, and the first abutment block 4413 moves synchronously with the horizontal abutment cylinder 441, and the first abutment block 4413 gradually approaches the outer wall of the flange, and then the first abutment block 4413 abuts against the outer wall of the flange, and the slider 422 still moves in the first slide groove 412, but the first abutment block 4413 cannot continue to move, so that the first abutment block 4413 drives the first telescopic rod 4412 to retract into the interior of the horizontal abutment cylinder 441, and the first telescopic rod 4412 drives the first piston 4411 to move toward the tail end of the horizontal abutment cylinder 441, and the first piston 4411 not only squeezes the interior of the horizontal abutment cylinder 441, but also squeezes the first spring 4414 into a compressed state. The hydraulic oil in the horizontal abutment cylinder 441 is squeezed into the first connecting head 4415, and then enters the second connecting head 4424 through the pipeline, and then the hydraulic oil enters the vertical abutment cylinder 442. The hydraulic oil entering the vertical abutment cylinder 442 squeezes the second piston 4421, and the second piston 4421 moves downward. The second piston 4421 drives the second telescopic rod 4422 to extend outward, and the second telescopic rod 4422 drives the second abutment block 4423 to move downward, and the second abutment block 4423 gradually abuts against the top edge of the flange, and then the second motor 43 stops working, so that the workpiece to be processed can be firmly clamped, and this method can also clamp and fix workpieces with different outer diameters to be processed.

[0044] During this process, the calibration mechanism 5 can play the role of calibration and centering. The calibration mechanism 5 includes an embedded plate 51 and a calibration plug 52. The bottom of the embedded plate 51 is provided with four guide rods 53 arranged at equal angles around its circumference. A second spring 531 is sleeved on the guide rod 53. A limit plate 532 is provided at the bottom of the guide rod 53. A third telescopic hole 511 is opened in the middle of the embedded plate 51. Four guide ears 521 that cooperate with the guide rod 53 are provided on the outer wall of the calibration plug 52 near its bottom. The guide ears 521 are in contact with one end of the second spring 531, and the calibration plug 52 is slidably set in the third telescopic hole 511.

[0045] When placing the workpiece, first align the flange hole of the workpiece to be processed with the calibration plug 52, and the calibration plug 52 guides the workpiece to be processed to the center.

[0046] After the workpiece is clamped, the first motor 22 drives the first rotating shaft 13 to rotate, and the first rotating shaft 13 drives the workbench to rotate 90 degrees. The workpiece is moved to the turning station, and then the first driving mechanism 7 works. The first driving mechanism 7 includes a longitudinal moving electric cylinder 72 and a third motor 73. An L-shaped first mounting plate 721 is installed on the slide of the longitudinal moving electric cylinder 72. A top ring plate 71 is provided in the inner groove 411. The rotating cylinder 41 is located in the top ring plate 71. The inner wall of the top ring plate 71 slides with the outer wall of the rotating cylinder 41. The bottom of the top ring plate 71 is provided with a built-in rotating seat 711, and a transmission member 74 is rotatably provided on the built-in rotating seat 711. A third gear 75 is provided at the bottom of the transmission member 74, and a ring gear 76 is provided on the outer wall of the rotating cylinder 41. The longitudinal moving electric cylinder 72 is arranged on the inner wall of the mounting bracket 2, and the third motor 73 is mounted on the first mounting plate 721. The ring gear 76 is engaged with the third gear 75. The output end of the third motor 73 is selectively connected to the transmission member 74, and the second drive mechanism 9 has the same structure as the first drive mechanism 7.

[0047] The transmission member 74 includes a transmission shaft 741 and a transmission plug 742 with a polygonal cross-section. The output end of the third motor 73 is provided with a plug sleeve 731 that is plugged into the transmission plug 742. The transmission shaft 741 is rotatably set on the built-in rotating seat 711. The third gear 75 is set at the bottom of the transmission shaft 741, and the transmission plug 742 is set at the top of the transmission shaft 741.

[0048] A second sliding groove 7411 with a polygonal cross-section is provided at the top of the transmission shaft 741, and a telescopic column 7412 is slidably provided in the second sliding groove 7411. A third spring 7413 is provided between the bottom of the telescopic column 7412 and the bottom of the second sliding groove 7411. A second L-shaped mounting plate 712 is provided at the top of the top ring plate 71, and a plug hole 713 is provided on the second mounting plate 712 for plugging with the transmission plug column 742. The transmission plug column 742 is arranged on the top of the telescopic column 7412.

[0049] After the first engaging groove 7411 is opened, the second engaging groove 7412 is pushed upwards and the second engaging groove 7413 is pushed downwards, so that the second engaging groove 7412 is pushed downwards and the second engaging groove 7413 is pushed downwards. The retracted column 7412 loses the limit lock of the plug hole 713 on the second mounting plate 712, and then the third motor 73 drives the plug sleeve 731 to rotate, and the plug sleeve 731 drives the transmission plug column 742 to rotate synchronously, and the transmission plug column 742 drives the telescopic column 7412 to rotate, and the telescopic column 7412 drives the transmission shaft 741 to rotate synchronously, and the transmission shaft 741 drives the third gear 75 to rotate, and the third gear 75 drives the ring gear 76 to rotate, and the ring gear 76 drives the rotating cylinder 41 to rotate on the annular rotating seat 111, and the rotating cylinder 41 drives the workpiece to be processed to rotate.

[0050] Subsequently, the turning mechanism 6 works to turn the workpiece to be processed. The turning mechanism 6 includes a transverse moving electric cylinder 61, a first lifting electric push rod 62 and a third mounting plate 63. A U-shaped frame 64 is installed on the slide of the transverse moving electric cylinder 61. A turning tool rod 65 is provided at the bottom of the third mounting plate 63. A detachable turning tool 66 is provided at the end of the turning tool rod 65. The transverse moving electric cylinder 61 is arranged on the inner top wall of the mounting bracket 2, the first lifting electric push rod 62 is arranged on the U-shaped frame 64, and the third mounting plate 63 is horizontally arranged on the output end of the first lifting electric push rod 62.

[0051] The horizontal moving electric cylinder 61 can drive the first lifting electric push rod 62 and the turning tool rod 65 to move left and right, and the first lifting electric push rod 62 drives the turning tool rod 65 to move up and down, thereby realizing the left and right and up and down two-axis adjustment movement of the turning tool 66. In conjunction with the rotation of the workpiece to be processed, the workpiece to be processed can be automatically turned. After turning is completed, the first lifting electric push rod 62 and the horizontal moving electric cylinder 61 drive the turning tool 66 to return to the initial position, and then the longitudinal moving electric cylinder 72 drives the third motor 73 to move upward, and the plug sleeve 731 gradually removes the abutment force on the telescopic column 7412, and the plug sleeve 731 also gradually disengages The transmission plug 742 and the third spring 7413 drive the telescopic column 7412 to move up in the second slide groove 7411 through its own elastic force, and the telescopic column 7412 drives the transmission plug 742 to move up synchronously, and then the telescopic column 7412 is gradually inserted into the plug hole 713 of the second mounting plate 712. The telescopic column 7412 is locked, and the transmission shaft 741 can avoid deflection. In order to prevent the telescopic column 7412 from accidentally disengaging from the second slide groove 7411, a limit ring 714 is provided on the top of the second mounting plate 712, and the limit ring 714 is used to limit the extended position of the telescopic column 7412.

[0052] Afterwards, the first motor 22 continues to work to drive the workbench to rotate 90 degrees, and the workpiece to be processed is moved to the drilling station. Then the drilling mechanism 8 drills the workpiece. The drilling mechanism 8 has the same structure as the drilling mechanism in CN118650438B and its working principle is also the same, so it will not be repeated here.

[0053] After the drilling operation is completed, the first motor 22 continues to work to drive the workbench to rotate 90 degrees, and the workpiece to be processed is moved to the boring station. Then the boring mechanism 10 performs finish processing on the workpiece to be processed. At this time, since the workpiece to be processed is in an inverted state, the debris retained on the top surface of the rotating cylinder 41 can automatically fall into the collecting bottom trough 3.

[0054] The boring mechanism 10 includes a second lifting electric push rod 101, a boring bar 102 and an air pump. A finishing boring bar 103 is provided on the top of the boring bar 102, and an annular nozzle head 104 is provided on the outer wall of the boring bar 102. The annular nozzle head 104 is provided with a plurality of evenly distributed nozzle holes 105. The second lifting electric push rod 101 is arranged on the top of the fence plate 31, and the boring bar 102 is connected to the output end of the second lifting electric push rod 101. The air pump is arranged on the inner wall of the mounting bracket 2, and the air pump is connected to the annular nozzle head 104 through a pipe.

[0055] The second lifting electric push rod 101 drives the boring bar 102 to move upward, and the finishing boring tool 103 on the top of the boring bar 102 can gradually enter the flange hole of the workpiece to be processed. At the same time, the second driving mechanism 9 works synchronously to drive the workpiece to be processed to rotate. The working principle of the second driving mechanism 9 is the same as that of the first driving mechanism 7. The finishing boring tool 103 can finish the flange hole. When the finishing boring tool 103 hits the calibration plug 52, the calibration plug 52 can be retracted into the third telescopic hole 511, which will not hinder the precision of the flange hole. During machining, the calibration plug 52 drives all the guide ears 521 to move synchronously, and the guide ears 521 squeeze the second spring 531, and the second spring 531 becomes compressed.
