[0029] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example 1:

[0031] Reference Figures 1-5 This application discloses a multi-angle drilling device for a material cylinder, comprising a worktable 1, a mounting frame 2 on the worktable 1, and a clamping chuck 3 on the worktable 1 for clamping and rotating the material cylinder 41. This clamping chuck 3 is similar to a three-grip chuck in the prior art. A working groove 37 is formed on the worktable 1, and several lifting cylinders 38 are arranged within the working groove 37. The telescopic ends of the lifting cylinders 38 are vertically upward, and support frames 39 are fixed to the telescopic ends of the lifting cylinders 38. Several support rollers 40 for supporting the material cylinder 41 are rotatably mounted on the support frames 39. Through the arrangement of the support rollers 40 and the lifting cylinders 38, the material cylinder 41 located on them can be effectively lifted and lowered, and stable support is provided when the material cylinder 41 is clamped by the clamping chuck 3 and driven to rotate.

[0032] like Figure 1As shown, the mounting frame 2 is provided with a punching member for punching the barrel 41, the punching member comprises a fixed block 4, a fixed sleeve 5, a punching motor 6 and a punching oil cylinder 7, the fixed block 4 is arranged on the mounting frame 2, a vertical sliding hole 8 is formed in the fixed block 4, the fixed sleeve 5 is slidingly arranged in the sliding hole 8, the punching motor 6 is fixedly arranged in the fixed sleeve 5, the output end of the punching motor 6 is vertically downward, and a drill bit 9 is arranged on the output end of the punching motor 6, the punching oil cylinder 7 is fixedly arranged in the fixed block 4, and the telescopic end of the punching oil cylinder 7 vertically downward extends into the sliding hole 8 and is fixedly connected with one end of the fixed sleeve 5. In this way, the fixed sleeve 5 can be driven to slide in the sliding hole 8 of the fixed block 4 by the punching oil cylinder 7, and the drill bit 9 can be driven to rotate by the punching motor 6, so as to punch the target position.

[0033] As shown in Figure 1 and Figure 2 shown, the mounting frame 2 is further provided with an adjusting member for adjusting the punching angle of the punching member, the adjusting member comprises an arc-shaped driving plate 10, a connecting rod 11, a first screw 12 and an adjusting sleeve 13, the driving plate 10 is slidingly arranged on the mounting frame 2 with the chucking chuck 3 as the axis, an arc-shaped guide hole 17 is formed in the driving plate 10, a guide block 18 is arranged on the mounting frame 2, the guide block 18 slidingly extends into the guide hole 17, the fixed block 4 is fixedly arranged on the driving plate 10, one end of the connecting rod is fixedly arranged on the fixed block 4, the first screw 12 is rotatably arranged on the mounting frame 2, the adjusting sleeve 13 is threadedly sleeved on the first screw 12, the side wall of the adjusting sleeve 13 slidingly abuts against the mounting frame 2, the mounting frame 2 is provided with a first motor 14 for driving the first screw 12 to rotate, a vertical sliding groove 15 is formed in the connecting rod 11, a sliding block 16 is fixedly arranged on the adjusting sleeve 13, the sliding block 16 is slidingly arranged in the sliding groove 15 and slidingly abuts against the side wall of the sliding groove 15. The adjusting sleeve 13 is moved on the first screw 12 by the rotation of the first motor 14, and the connecting rod 11 and the fixed block 4 connected with the adjusting sleeve 13 are moved, because the driving plate 10 slides with the chucking chuck as the axis, when the driving plate 10 slides, the drill bit 9 also rotates at an angle.

[0034] As shown in Figure 3 a plurality of positioning holes 19 are formed in the driving plate 10, a first air cylinder 20 is fixedly arranged on the mounting frame 2, a first positioning pin 21 is fixedly arranged on the telescopic end of the first air cylinder 20, and the first positioning pin 21 is used to extend into one of the positioning holes 19. The first positioning pin 21 can be effectively extended into the positioning hole 19 by the telescopic movement of the first air cylinder 20, so as to position the position of the driving plate 10 on the mounting frame 2.

[0035] Working principle:

[0036] First, the material cylinder 41 to be processed is placed on the support roller 40 of the support frame 39 driven by several lifting cylinders 38. After the material cylinder 41 is adjusted to a suitable height by the lifting cylinders 38, it is clamped by the clamping chuck 3 on the worktable 1 and can be driven to rotate during processing. When it is necessary to drill holes in the material cylinder 41 at multiple angles, the first motor 14 in the adjusting component is started, driving the first screw 12 to rotate, which drives the threaded adjusting sleeve 13 to move along the screw. The adjusting sleeve 13 cooperates with the sliding groove 15 of the connecting rod 11 through the slider 16 on it, pushing the connecting rod 11 to move, which in turn drives the fixed block 4 and the entire drilling part on it to slide along an arc trajectory around the axis of the clamping chuck 3 with the drive plate 10, thereby accurately adjusting the pointing angle of the drill bit 9. After the angle is adjusted to the correct position, the first cylinder 20 pushes the first positioning pin 21 to insert into the corresponding positioning hole 19 of the drive plate 10, locking the position of the drive plate 10 and the drilling part. Subsequently, the drilling motor 6 is started to drive the drill bit 9 to rotate at high speed. At the same time, the telescopic end of the drilling cylinder 7 extends downward, pushing the fixed sleeve 5, together with the drilling motor 6 and the drill bit 9, to feed downward along the sliding hole 8 of the fixed block 4, completing the drilling operation on the clamped material cylinder 41. By rotating the material cylinder 41 through the clamping chuck 3 and combining it with the angle adjustment, continuous drilling of the material cylinder 41 in the circumference and multiple angles can be achieved in one clamping, and the holes and slots can be interconnected to form a cooling channel 42.

[0037] Example 2:

[0038] Compared with Example 1, the following differences exist: Figure 6 , Figure 7 and Figure 8 As shown, the adjusting component includes a sliding frame 22, a connecting block 23, an adjusting rod 24, a worm gear 25, and a worm 26. The sliding frame 22 is horizontally slidably mounted on the mounting frame 2. The connecting block 23 is fixedly mounted on the fixing block 4. One end of the adjusting rod 24 is rotatably mounted on the sliding frame 22, and the other end of the adjusting rod 24 is fixedly connected to the connecting block 23. The worm gear 25 is fixedly mounted on the adjusting rod 24. The worm 26 is horizontally and rotatably mounted on the sliding frame 22, and the worm 26 meshes with the worm gear 25. A second motor 27 is provided on the sliding frame 22 to drive the worm 26 to rotate. This configuration allows the worm 26 to drive the worm gear 25 to rotate, which in turn drives the adjusting rod 24 and the connecting block 23 to rotate the fixing block 4, thereby adjusting the drilling angle.

[0039] like Figure 8 , Figure 9 and Figure 10As shown, a second positioning pin 28 slides through the worm gear 26, and several positioning slots 29 are formed around the connecting block 23 along the adjusting rod 24. A push plate 30 is provided on the sliding frame 22 to push the second positioning pin 28 towards the connecting block 23. A second cylinder 31 is fixed to the sliding frame 22, and the telescopic end of the second cylinder 31 is fixedly connected to the push plate 30. A spring block 32 slides in each positioning slot 29, one end of which abuts against the second positioning pin 28. A spring 33 is fixed between the spring block 32 and the bottom of the positioning slot 29. By driving the push plate 30 through the second cylinder 31, the second positioning pin 28 can be effectively pushed to slide on the worm gear 25, abutting against the spring block 32 in one of the positioning slots 29 and extending into the positioning slot 29, ensuring the stability of the angle after the connecting block 23 rotates.

[0040] like Figure 7 As shown, the mounting frame 2 is equipped with a guide rail 34, and the sliding frame 22 is slidably mounted on the guide rail 34. A second screw 35 is also rotatably mounted on the mounting frame 2, and one end of the sliding frame 22 is threaded onto the second screw 35. The mounting frame 2 is equipped with a third motor 36 for driving the second screw 35 to rotate. The third motor 36 can effectively drive the second screw 35 to rotate and cause the sliding frame 22 to slide on the mounting frame 2, thereby adjusting the position of the drill bit 9 relative to the barrel 41.

[0041] Working principle:

[0042] First, the material cylinder 41 is placed on the support roller 40 and clamped and fixed by the clamping chuck 3. Then, the second screw 35 is driven to rotate by the third motor 36, which drives the threaded sliding frame 22 to slide horizontally along the guide rail 34 on the mounting frame 2, thereby adjusting the lateral position of the entire drilling part relative to the material cylinder 41. When it is necessary to adjust the drilling angle, the second motor 27 is started to drive the worm gear 26 to rotate, which drives the worm wheel 25 meshing with it to rotate. This causes the connecting block 23 fixed to one end of the adjusting rod 24 to drive the fixing block 4 and the entire drilling part to rotate around the axis of the adjusting rod 24, thereby achieving precise adjustment of the drill bit 9 angle. After the angle is set, the second air... Cylinder 31 pushes push plate 30, causing second positioning pin 28, which slides through worm gear 26, to move towards connecting block 23 until its end abuts against and inserts into spring block 32 in corresponding positioning groove 29 on connecting block 23. With the assistance of spring 33, stable locking is achieved, ensuring the reliability of angle during processing. Finally, drilling motor 6 is started to drive drill bit 9 to rotate at high speed. At the same time, drilling cylinder 7 pushes fixed sleeve 5 and drill bit 9 downward to drill cylinder 41. Combined with the rotation drive of cylinder 41 by clamping chuck 3, continuous drilling processing of multiple positions and angles on the surface of cylinder 41 can be completed in one clamping.
