Description

Technical Field

[0001] The utility model relates to the technical field of oil production, in particular to a numerical control drill head for processing blind holes in the body of an oil production perforating gun barrel. Background Art

[0002] The body of an oil production perforating gun barrel is an important component in the process of oil extraction. It is mainly used for perforating the casing of an oil and gas well to provide a channel for the flow of oil and gas. By perforating at specific positions, the oil and gas in the formation can smoothly flow into the wellbore, thus realizing efficient oil production operations. It usually performs blind hole processing through a drill bit to provide an accurate installation position for the perforating charge, ensure the position of the perforating charge is fixed in the gun barrel, and ensure that it can accurately shoot at the predetermined formation position during the perforating operation.

[0003] Traditional blind hole processing drill bits usually consist of a drill shank and a drill body. There is a cutting edge at the front end of the drill body, which is mostly designed in a spiral shape, facilitating chip removal and cutting. It has distinct characteristics, a strong and durable structure, can adapt to various processing scenarios, a sharp cutting edge, can efficiently cut materials, the blind holes processed have relatively accurate dimensions, and the spiral groove design can effectively discharge chips to prevent blockage. Its operation is relatively simple and is widely used in various mechanical processing fields.

[0004] However, for traditional blind hole processing drill bits, the drill bit and the drill shank are usually fixedly connected, which makes it impossible to disassemble them conveniently during use. When the drill bit wears out and needs to be replaced, it often takes a lot of time and effort, and even professional tools may be required. This fixed connection also limits the versatility and flexibility of the drill bit and reduces work efficiency. Therefore, a numerical control drill head for processing blind holes in the body of an oil production perforating gun barrel is proposed to solve the above problems. Summary of the Utility Model

[0005] To make up for the above deficiencies, the utility model provides a numerical control drill head for processing blind holes in the body of an oil production perforating gun barrel, aiming to improve the problem that the drill bit and the drill shank cannot be disassembled from each other conveniently in the existing technology.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The NC drill head for machining blind holes inside the oil production perforating gun barrel body includes a drill body. A rotating handle is arranged on one side of the drill body. An expansion column is slidably connected inside the rotating handle. A fixed column is slidably connected inside the expansion column. A second clamping groove is formed inside the fixed column. One end of the fixed column is fixedly connected to one end of the drill body. A first spring is arranged inside the expansion column.

A limiting ring is fixedly connected to the outer wall of the connecting column. The outer wall of the clamping block is slidably connected inside the second clamping groove. A starting component is arranged inside the connecting column, and the starting component is used to move the connecting column;

[0008] As a further description of the above technical solution:

[0009] The starting component includes a limiting tube and a pull ring. The outer wall of the pull ring is arranged inside the connecting column.

[0033] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figure 1 - Figure 4 , an embodiment provided by the present invention: a numerical control drill head for machining blind holes in the body of an oil production perforating gun barrel, including a drill body 1. The drill body 1 is made of high-strength alloy steel and undergoes precise processing technology to ensure its smooth surface and precise dimensions. The spiral cutting edge of the drill body 1 has a unique design, which can efficiently cut materials and has good wear resistance and corrosion resistance. A rotating handle 2 is arranged on one side of the drill body 1. A telescopic column 5 is slidably connected inside the rotating handle 2. The telescopic column 5 is made of stainless steel and has high strength and hardness. The surface of the telescopic column 5 is polished, with high smoothness, reducing the frictional resistance with the inside of the rotating handle 2. A fixed column 6 is slidably connected inside the telescopic column 5. The fixed column 6 is also made of high-strength alloy steel, matching the material of the drill body 1 to ensure the firmness and stability of the connection. A second clamping groove 14 is opened inside the fixed column 6. One end of the fixed column 6 is fixedly connected to one end of the drill body 1. A first spring 11 is arranged inside the telescopic column 5. One end of the first spring 11 is fixedly connected to the inside of the telescopic column 5, and the other end of the first spring 11 is fixedly connected to a connecting plate 12. A clamping block 13 is fixedly connected to the bottom of the connecting plate 12. The clamping block 13 is made of high-strength alloy steel and has high hardness and wear resistance. The shape and size of the clamping block 13 match the second clamping groove 14, and it can tightly fit into the second clamping groove 14 to realize the connection between the fixed column 6 and the telescopic column 5. A connecting column 8 is fixedly connected to one side of the clamping block 13. A limiting ring 10 is fixedly connected to the outer wall of the connecting column 8. The outer wall of the clamping block 13 slides inside the second clamping groove 14. A starting component is arranged inside the connecting column 8. The starting component acts on moving the connecting column 8, so as to facilitate disassembly and assembly, and it can be adjusted according to the usage situation.

[0035] Specifically, according to the specific processing situation, the movable connecting column 8 can be moved. Then, the movement of the connecting column 8 drives the sliding block 13 to slide inside the second clamping groove 14, thereby releasing the fixation of the fixed column 6, so that it can be replaced. At the same time, the movement of the sliding block 13 also drives the connecting plates 12 on both sides to move together, thereby compressing the first spring 11. After the replacement is completed, the connecting column 8 is released. At this time, the first spring 11 rebounds and drives the sliding block 13 to slide back into the second clamping groove 14 to firmly fix the replaced fixed column 6. Thus, different parts of the drill body 1 can be spliced according to different processing requirements to adapt to various processing scenarios. There is no need to purchase multiple complete drill bits, only the required splicing parts need to be purchased, which reduces costs. At the same time, the splicing parts can be quickly replaced, reducing the downtime during the processing, improving production efficiency. And when a certain part is worn, only that part needs to be replaced instead of the whole drill bit, extending the service life of the drill bit. Different splicing parts can also be stored separately for easy management and maintenance, and appropriate splicing parts can be selected according to specific processing requirements to improve processing accuracy.

[0036] Refer to Figure 2 and Figure 4 , the starting component includes a limiting tube 4 and a pull ring 9. The outer wall of the pull ring 9 is arranged inside the connecting column 8, the inside of the limiting tube 4 is arranged inside the rotating handle 2, and the outer wall of the connecting column 8 is slidably connected inside the limiting tube 4.

[0037] Specifically, the limiting tube 4 limits the connecting column 8 to prevent it from shaking during use, and the pull ring 9 facilitates the movement of the connecting column 8 by personnel.

[0038] Refer to Figure 1 、 Figure 5 and Figure 6, a groove 3 is provided inside the rotating handle 2, and a first clamping groove 7 is provided inside the telescopic column 5. The size of the first clamping groove 7 is precisely calculated to be able to closely cooperate with the pressing plate 20 to achieve stable connection. A rotating column 17 is rotatably connected inside the rotating handle 2. The rotating column 17 is made of strong alloy steel and its surface is chrome-plated, which is not only beautiful but also has good rust prevention performance. Both ends of the rotating column 17 are connected to the rotating handle 2 through high-precision bearings to ensure smooth and stable rotation. An eccentric wheel 16 is fixedly connected to the outer wall of the rotating column 17, and a rotating handle 15 is fixedly connected to the outer wall of the eccentric wheel 16. The rotating handle 15 is made of anti-slip rubber material, with a comfortable grip and convenient operation. The shape design of the rotating handle 15 conforms to the ergonomic principle, enabling the operator to be more labor-saving when using it. A fixing plate 21 is slidably connected to the bottom of the eccentric wheel 16, and a pressing plate 20 is fixedly connected to the bottom of the fixing plate 21. The pressing plate 20 is made of tool steel with relatively high hardness and can withstand large pressures. The outer wall of the pressing plate 20 is slidably connected inside the first clamping groove 7. A lifting column 18 is fixedly connected to the top of the pressing plate 20. The outer wall of the lifting column 18 is slidably connected inside the rotating handle 2. A second spring 19 is sleeved on the outer wall of the lifting column 18. The top of the second spring 19 is fixedly connected inside the rotating handle 2, and the bottom of the second spring 19 is fixedly connected to the top of the pressing plate 20, so that the length of the drill bit can be conveniently adjusted to use different machining depths.

[0039] Specifically, according to the machining situation, the rotating handle 15 can be gently toggled first. By rotating the rotating handle 15, the eccentric wheel 16 is driven to rotate at a constant speed, and at the same time, the rotating column 17 is prompted to rotate smoothly inside the rotating handle 2, so as to relieve the pressure applied to the fixing plate 21, enabling the second spring 19 to rebound and driving the pressing plate 20 to rise. Only then can the drill body 1 be pulled to move, driving the telescopic column 5 to move out, and at the same time driving the connecting column 8 to smoothly slide out from the inside of the limiting tube 4, so as to be movable. When it moves to an appropriate length, turn the rotating handle 15 back to drive the eccentric wheel 16 to apply pressure to the fixing plate 21 again, thereby driving the pressing plate 20 to separate from the first clamping groove 7, firmly fixing the telescopic column 5, and at the same time pulling the second spring 19 for subsequent use. In this way, the length can be adjusted according to different machining requirements, without frequently replacing the drill bit, reducing the time for replacing the drill bit, improving the machining efficiency, reducing the number of drill bits used, lowering the cost, and at the same time being able to more accurately control the machining depth, improving the machining accuracy, and the telescopic drill bit handle makes the tool more compact, convenient for carrying and storing.

[0040] Working principle: Adjust the drill bit according to the machining situation. First, turn the rotary handle 15. The rotary handle 15 drives the eccentric wheel 16 to rotate, and at the same time drives the rotating column 17 to rotate inside the rotating handle 2, thereby relieving the pressure applied to the fixed plate 21, causing the second spring 19 to rebound and drive the pressing plate 20 to rise. Then, the drill body 1 can be pulled to move, driving the telescopic column 5 to move out, and at the same time driving the connecting column 8 to slide out of the limiting tube 4 for movement. After reaching the appropriate length, turn the rotary handle 15 back, driving the eccentric wheel 16 to apply pressure to the fixed plate 21, thereby driving the pressing plate 20 to disengage from the first clamping groove 7, fixing the telescopic column 5, and at the same time pulling the second spring 19 for convenient subsequent use. Then, the connecting column 8 can be driven to move through the pull ring 9, and then the clamping block 13 is driven by the connecting column 8 to slide inside the second clamping groove 14 to release the fixation of the fixed column 6, and it can be replaced. At the same time, the movement of the clamping block 13 drives the connecting plates 12 on both sides to move, compressing the first spring 11. After the replacement is completed, release the connecting column 8, and the first spring 11 rebounds to drive the clamping block 13 to slide back into the second clamping groove 14 to fix the replaced fixed column 6, so as to accurately machine the barrel.
