The second arc-shaped rotating frame 34 is arranged in a semicircular shape, the center of the second arc-shaped rotating frame 34 coincides with the center of the second arc-shaped mounting frame 31, second mounting grooves 35 are arranged on both sides of the second arc-shaped rotating frame 34, and second racks 36 are arranged on the inner wall of the second mounting grooves 35. The second driving gear 32 is arranged in the second mounting grooves 35, and the second driving gear 32 and the second racks 36 are meshed with each other. A second CNC telescopic gas rod 37 is fixedly mounted on the inner wall of the second arc-shaped rotating frame 34, and another set of push-pull clamping components 47 is mounted on the output shaft of the second CNC telescopic gas rod 37; A driving ring 40 is fixedly connected inside the second arc-shaped mounting frame 31. The driving ring 40 is arranged on a side of the second arc-shaped mounting frame 31 close to the second rotating frame 30. The driving ring 40 and the second arc-shaped mounting frame 31 are perpendicular to each other. At the same time, the rotation axis of the driving ring 40 coincides with the rotation axis of the second rotating frame 30. A third rack 41 is arranged inside the outer wall of the driving ring 40. A fifth CNC motor 42 is installed on the supporting mounting frame 28. A third driving gear 43 is fixedly connected to the output shaft of the fifth CNC motor 42. The third driving gear 43 coincides with the third rack 41. A third CNC telescopic gas rod 38 is fixedly installed at the bottom of the second arc-shaped rotating frame 34, and a bracket 39 is fixedly connected to the output shaft of the third CNC telescopic gas rod 38, and the center point of the bracket 39 coincides with the rotation axis of the second arc-shaped rotating frame 34; The second numerical control motor 18, the third numerical control motor 19, the fourth numerical control motor 33, the fifth numerical control motor 42, the sixth numerical control motor 44, the first numerical control telescopic gas rod 24, the second numerical control telescopic gas rod 37, and the third numerical control telescopic gas rod 38 are connected to the numerical control device; The drilling assembly 46 is mounted on the machine tool frame 1 and is used to drill holes in the workpiece; Before using the present invention, the device is reset to the initial state (such as Figure 1 As shown), at this time, the first arc rotating frame 20 is reset to a horizontal state, the second arc rotating frame 34 is reset to a vertical state, and the first CNC telescopic gas rod 24 and the second CNC telescopic gas rod 37 are reset to the same horizontal plane, and the workpiece can be placed on the bracket 39 (as shown in FIG. Fig. 9As shown), and align the drilling point with the midpoint of the bracket 39, at this time, the third numerical control telescopic gas rod 38 can be controlled by the numerical control device to extend, thereby driving the bracket 39 to rise, thereby lifting the workpiece to between the first numerical control telescopic gas rod 24 and the second numerical control telescopic gas rod 37, and then the numerical control device controls the first numerical control telescopic gas rod 24 and the second numerical control telescopic gas rod 37 to extend, thereby driving the push clamping assembly 47 to push the workpiece, and then the workpiece is clamped and fixed by the mutual cooperation of multiple groups of push clamping assemblies 47 (as shown in FIG. Fig.10 As shown), after the clamping is completed, the numerical control device controls the third numerical control telescopic gas rod 38 to contract, thereby driving the bracket 39 to descend and reset. In this process, the clamping height of the workpiece can be calculated according to the size and thickness of the workpiece and the drilling position, and the calculation result can be input into the numerical control device, or manual adjustment can be performed. After the clamping is completed, the extension length and the output holding force of the first numerical control telescopic gas rod 24 and the second numerical control telescopic gas rod 37 are memorized by the numerical control device, and then the lifting height of the bracket 39 and the clamping force output by the first numerical control telescopic gas rod 24 and the second numerical control telescopic gas rod 37 on the clamping distance of the workpiece are accurately controlled by the numerical control device, thereby realizing the clamping height of the workpiece and the digital control of the clamping position, thereby realizing the unified positioning and clamping of multiple groups of the same workpieces, without the need for workers to repeatedly adjust, reducing manual errors and improving the processing accuracy of the equipment; Then, the fourth CNC motor 33 is controlled by the CNC device to drive the second driving gear 32 to rotate. The second driving gear 32 drives the second arc rotating frame 34 to rotate 90° around the center of the second arc rotating frame 34 through mutual engagement with the second rack 36. At the same time, the second arc rotating frame 34 drives the two sets of second CNC telescopic gas rods 37 to rotate synchronously. At this time, the second CNC telescopic gas rods 37 drive the workpiece to rotate around the first CNC telescopic gas rods 24, thereby rotating the workpiece from a horizontal state to a vertical state, so that the surface to be processed is facing the drilling assembly 46 (such as Fig.11 shown); At the same time, when the drilling of surface A is completed and surface B needs to be processed, it is only necessary to control the second CNC telescopic gas rod 37 to retract through the CNC device, so that the second CNC telescopic gas rod 37 loses the clamping of the workpiece. At this time, the third CNC motor 19 can be used to drive the rotating connecting frame 15 to rotate, and the rotating connecting frame 15 drives the first arc rotating frame 20 to rotate around the rotation axis of the rotating connecting frame 15 through the first arc mounting frame 16, and the rotation angle of the first arc rotating frame 20 is controlled by the CNC device, so that the first arc rotating frame 20 rotates 180°. At this time, the first arc rotating frame 20 drives the workpiece to rotate synchronously through the first CNC telescopic gas rod 24, thereby rotating the workpiece, so that the workpiece rotates from the A side toward the drilling assembly 46 to the B side toward the drilling assembly 46. At this time, the first arc rotating frame 20 is driven by the first arc mounting frame 16 to rotate from the side away from the drilling assembly 46 to the side close to the drilling assembly 46 (such as Fig.12 shown); Afterwards, the fifth CNC motor 42 is controlled to rotate by the CNC device, and the fifth CNC motor 42 drives the third driving gear 43 to rotate. The third driving gear 43 drives the driving ring 40 to align with the axis of the driving ring 40 as the center through mutual engagement with the third rack 41. The driving ring 40 drives the two groups of second arc-shaped mounting frames 31 to rotate with the center of the driving ring 40 as the center, and before and after the rotation, the second arc-shaped mounting frames 31 are symmetrical with each other with the plane in the vertical direction where the center of the driving ring 40 is located as the symmetry plane. Afterwards, the two groups of second CNC telescopic gas rods 37 are controlled to extend through the CNC device, and the clamping forces output by the two groups of second CNC telescopic gas rods 37 on the clamping distance of the workpiece memorized by the CNC device are exchanged with each other. At this time, the two groups of second CNC telescopic gas rods 37 and the workpiece complete the synchronous rotation adjustment, so that the workpiece is clamped and fixed again, and the two groups of second CNC telescopic gas rods 37 are rotated before and after the workpiece is flipped. The clamping point, clamping distance and clamping force between the CNC telescopic gas rod 37 and the workpiece are the same, so as to achieve accurate clamping and fixation of the workpiece, thereby improving the processing accuracy of the equipment. After the workpiece is clamped by the second CNC telescopic gas rod 37, the CNC device controls the first CNC telescopic gas rod 24 to retract, so that the push clamping assembly 47 on the first CNC telescopic gas rod 24 is retracted into the storage groove 27, and then the second CNC motor 18 drives the first driving gear 17 to rotate. The first driving gear 17 drives the first arc rotating frame 20 to rotate by mutual engagement with the first rack 22, so that the first arc rotating frame 20 rotates from the side close to the drilling assembly 46 to the side away from the drilling assembly 46, and in this process, the storage groove 27 is used to store the push clamping assembly 47, so as to avoid mutual interference between the first CNC telescopic gas rod 24 and the second rotating frame 30 and the third rack 41 (such as Fig.13As shown in FIG. 1 ), the first CNC telescopic gas rod 24 is then extended through the CNC device to clamp and fix the workpiece again, thereby completing the automatic flip clamping of the workpiece (as shown in FIG. 1 ). Fig.14 shown); At the same time, when the present invention clamps and fixes the workpiece, the relative angle between the first CNC telescopic gas rod 24 and the second CNC telescopic gas rod 37 can be adjusted by rotating the first arc-shaped rotating frame 20, so as to fully adjust the clamping point and the clamping angle of the workpiece in the horizontal direction. At the same time, the clamping angle between the first CNC telescopic gas rod 24 and the second CNC telescopic gas rod 37 in the vertical direction can be fully adjusted by rotating the second arc-shaped rotating frame 34 and the first rotating frame 14, thereby realizing three-axis adjustable clamping of the workpiece. In addition, the present invention uses a CNC device to precisely control the operation of the first CNC motor 6, the second CNC motor 18, the third CNC motor 19, the fourth CNC motor 33, the fifth CNC motor 42, the sixth CNC motor 44, the first CNC telescopic gas rod 24, the second CNC telescopic gas rod 37, and the second CNC telescopic gas rod 37, and performs programmable automatic control, thereby realizing programmable clamping processing of the workpiece.

The ball screw 4 then converts the rotary motion of the first CNC motor 6 into the linear motion of the driving cylinder 5. The driving cylinder 5 drives the sliding seat 3 to slide, and the sliding seat 3 drives the drill bit 9 to move through the first mounting bracket 7, so as to adjust the relative distance between the drill bit 9 and the workpiece, and then the drill bit 9 is driven to rotate by the high-speed motor 8, and then the workpiece is rotationally cut. At the same time, the drilling component 46 can also control the start and stop speed of the first CNC motor 6 through the CNC device to adjust, so as to realize programmable control of the position of the drill bit 9 and the feed speed.
