Description

Technical Field

[0002] With the advancement of technology and the development of the manufacturing industry, CNC deep-hole drilling has become an essential component of machining due to its high-precision, high-efficiency, and highly automated deep-hole processing capabilities. This expansion in deep-hole processing has enabled gun drilling to produce holes perpendicular to the workpiece's locating surface features. However, due to machining constraints imposed by the workpiece's geometry, the non-perpendicular relationship between the locating surface and the machined hole position has made deep-hole processing impossible.

[0003] However, in the prior art, there are many deficiencies in the bevel hole processing device that adapts to the non-perpendicular relationship between the positioning surface and the hole position.

The output shaft of the fourth CNC motor 33 is fixedly connected to the second drive gear 32, and the two sets of fourth CNC motors 33 are distributed in a circular symmetrical manner.

[0051] The second arc-shaped rotating frame 34 is arranged in a semicircular shape, and the center of the second arc-shaped rotating frame 34 coincides with the center of the second arc-shaped mounting frame 31.

[0052] 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 pushing and clamping components 47 is mounted on the output shaft of the second CNC telescopic gas rod 37 ;

[0053] A driving ring 40 is fixedly connected to 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.

[0056] The drilling assembly 46 is mounted on the machine tool frame 1 and is used to drill holes in the workpiece;

[0057] 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. At this time, the workpiece can be placed on the bracket 39 (as shown). Figure 9 As shown), and align the drilling point with the midpoint of the bracket 39, the numerical control device can be used to control the third numerical control telescopic gas rod 38 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 pushing and clamping assembly 47 to push the workpiece, and then the workpiece is clamped and fixed by the mutual cooperation of multiple groups of pushing and clamping assemblies 47 (as shown). Figure 10 As shown), after the clamping is completed, the CNC device controls the third CNC telescopic gas rod 38 to retract, thereby driving the bracket 39 to descend and reset. During 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 CNC device, or manual adjustment can be performed. After the clamping is completed, the extension length and output holding force of the first CNC telescopic gas rod 24 and the second CNC telescopic gas rod 37 are memorized by the CNC device, and then the lifting height of the bracket 39 and the clamping force output by the first CNC telescopic gas rod 24 and the second CNC telescopic gas rod 37 on the clamping distance of the workpiece are accurately controlled by the CNC device, thereby realizing digital control of the clamping height and clamping position of the workpiece, thereby realizing unified positioning and clamping of multiple groups of identical workpieces, without the need for workers to repeatedly adjust, reducing manual errors and improving the processing accuracy of the equipment;

[0058] Then, the fourth CNC motor 33 is controlled by the CNC device to drive the second drive gear 32 to rotate. The second drive gear 32 drives the second arc-shaped rotating frame 34 to rotate 90 degrees around the center of the second arc-shaped rotating frame 34 through mutual engagement with the second rack 36. At the same time, the second arc-shaped 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, thereby turning the surface to be processed toward the drilling assembly 46 (such as Figure 11 shown);

[0059] 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 air rod 37 to retract through the CNC device, so that the second CNC telescopic air rod 37 loses the clamping of the workpiece. At this time, the rotating connecting frame 15 can be driven to rotate by the third CNC motor 19, 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 air rod 24, thereby rotating the workpiece, so that the workpiece rotates from surface A toward the drilling assembly 46 to surface B 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 Figure 12 shown);

[0060] 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 be aligned with the axis of the driving ring 40 through mutual engagement with the third rack 41, and 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 rotation, the second arc-shaped mounting frames 31 are symmetrical with each other with the vertical plane where the center of the driving ring 40 is located as the symmetry plane. Then, 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, thereby clamping and fixing the workpiece again, and the two groups of second CNC telescopic gas rods 37 are turned over before and after the workpiece is flipped. The clamping point, clamping distance and clamping force between the CNC telescopic air rod 37 and the workpiece are all the same, thereby achieving precise clamping and fixing of the workpiece, thereby improving the processing accuracy of the equipment. After the workpiece is clamped by the second CNC telescopic air rod 37, the CNC device controls the first CNC telescopic air rod 24 to retract, thereby retracting the push clamping assembly 47 on the first CNC telescopic air rod 24 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 engaging with the first rack 22, thereby rotating the first arc rotating frame 20 from the side close to the drilling assembly 46 to the side away from the drilling assembly 46, and in this process, the storage of the push clamping assembly 47 by the storage groove 27 avoids mutual interference between the first CNC telescopic air rod 24 and the second rotating frame 30 and the third rack 41 (such as Figure 13 As shown) the first CNC telescopic gas rod 24 is then extended by the CNC device to clamp the workpiece again and complete the automatic flip clamping of the workpiece (as shown) Figure 14 shown);

[0061] At the same time, when the present invention clamps and fixes the workpiece, it can first adjust the relative angle between the first CNC telescopic air rod 24 and the second CNC telescopic air rod 37 by rotating the first arc-shaped rotating frame 20, thereby adjusting the clamping point and the clamping angle of the workpiece in the horizontal direction in all directions. At the same time, the clamping angle of the first CNC telescopic air rod 24 and the second CNC telescopic air rod 37 in the vertical direction can be adjusted in all directions by rotating the second arc-shaped rotating frame 34 and the first rotating frame 14, thereby realizing three-axis adjustable clamping of the workpiece, and the present invention uses the 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 air rod 24, the second CNC telescopic air rod 37, and the second CNC telescopic air rod 37, and performs programmable automatic control, thereby realizing programmable clamping processing of the workpiece.

The drilling assembly 46 drives the ball screw 4 to rotate through the first CNC motor 6. 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. The sliding seat 3 drives the drill bit 9 to move through the first mounting bracket 7, thereby adjusting the relative distance between the drill bit 9 and the workpiece, and then drives the drill bit 9 to rotate through the high-speed motor 8, thereby performing rotational cutting on the workpiece. At the same time, the drilling assembly 46 can also control the start and stop speed of the first CNC motor 6 through the CNC device to adjust, thereby realizing programmable control of the position of the drill bit 9 and the feed speed.
