Description

Technical Field

[0001] This utility model relates to the field of perforator technology, specifically to a tooling for processing blind holes in thin-walled perforators. Background Technology

[0002] With the development of production and science and technology, and the progress of society, the consumption of oil and natural gas is constantly increasing, and countries are also stockpiling them as important strategic resources. Therefore, all countries have accelerated their oil and natural gas extraction efforts, and perforating guns are an indispensable piece of equipment in oil and natural gas extraction.

[0003] Different rock formations, geological structures, and oil and gas reserves require different drilling diameters and depths, necessitating perforators of varying diameters. To meet these requirements, perforators with different diameters, lengths, and wall thicknesses have been designed. One type of thin-walled perforator is suitable for horizontal well drilling, but to maximize ammunition loading and ensure blasting depth, the pipe wall is thinner, which increases manufacturing difficulty. Auxiliary tooling is used to ensure product quality and production efficiency.

[0004] Existing thin-walled perforators require end face positioning during processing to accurately machine blind holes. However, directly clamping the threaded end will cause deformation of the thread and sealing surface, resulting in out-of-tolerance dimensions and direct scrapping. If the clamping force is reduced, the friction and the weight of the part will both affect the inability to rotate to the correct position, resulting in out-of-tolerance dimensions of the blind hole.

[0005] Therefore, based on product precision and production requirements, a blind hole processing fixture for thin-walled perforators was designed to assist in the blind hole process. This fixture can ensure that the sealing surface and threads of the parts will not be deformed during the processing, and can also ensure the accurate position of the blind hole processing. At the same time, it is easy to install and improves production efficiency while ensuring the pass rate. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: a blind hole processing fixture for a thin-walled perforator product, including a worktable 1 as the basic support platform for the entire fixture, bearing the installation and operation of all other components; a fixed plate 2 fixedly installed at one end of the worktable 1; a rotating disk 3 rotatably installed on the fixed plate 2; a fixed cylinder 4 fixedly set at the center of the rotating disk 3; an inner support structure 5 set on the fixed cylinder 4 for internal support and clamping of the inner wall of the thin tube; a drive assembly 6 set on the worktable 1 for driving the rotating disk 3 to rotate; a support structure 7 set at the other end of the worktable 1 for supporting the end of the fixed cylinder 4; during the clamping process, the thin-walled perforator tube is placed into the fixed cylinder 4, and the inner support structure 5 is activated to clamp the inner wall of the tube; The support structure 7 abuts against the end of the fixed cylinder 4, providing auxiliary support. During processing, the drive assembly 6 drives the rotating disk 3 to rotate smoothly. The rotating disk 3 drives the fixed cylinder 4 and the clamped pipe to rotate synchronously, realizing continuous processing of blind holes. Through the design of the inner support structure 5, after the thin pipe wall is placed on the outside of the fixed cylinder 4, it is internally supported by the inner support structure 5, which ensures the clamping force while avoiding deformation of the sealing surface or damage to the threads caused by directly clamping the thread end face, thus ensuring the structural integrity of the parts during processing. Through the self-locking performance of the worm gear of the drive assembly 6, combined with the auxiliary support of the support structure 5, the rotating disk 3 can rotate smoothly, reducing the impact of vibration on processing accuracy and ensuring the accuracy of the blind hole position and size.

[0028] Specifically, the internal support structure 5 includes a hydraulic cylinder 51 mounted on the rotating disk 3. The output end of the hydraulic cylinder 51 extends into the fixed cylinder 4 and is equipped with a drive rod 52. The side wall of the fixed cylinder 4 is provided with several evenly distributed strip-shaped openings 53. Several internal support rods 54 extending into the same strip-shaped opening 53 are hinged to the side wall of the drive rod 52. The other ends of the internal support rods 54 in the same strip-shaped opening 53 are hinged to an internal support clamp 55. The clamping end of the internal support clamp 55 is provided with an anti-slip pad 56. The anti-slip pad 56 covers the clamping end, and its shape is customized according to the inner wall contour of the thin-walled pipe to ensure a tight fit. The material is rubber or polymer. To prevent scratches on the workpiece surface and enhance friction, the inner support clamp 55 is slidably connected to the rotating disk 3 to guide movement and prevent the inner support clamp 55 from shifting. In actual use, the hydraulic cylinder 51 is activated to retract, driving the drive rod 52 to move along the fixed cylinder 4 towards the rotating disk 3, causing the drive rod 52 to drive the inner support rod 54 to rotate relative to it. The inner support rod 54 pushes the inner support clamp 55 to open through the hinge point. The anti-slip pad 56 of the inner support clamp 55 is tightly attached to the inner wall of the thin-walled pipe, and the clamping force is applied evenly through multi-point contact. The inner wall of the pipe is clamped by the inner support structure 5, avoiding direct contact with the threaded end face and preventing deformation of the sealing surface or damage to the threads.

[0029] Furthermore, pressure is maintained by hydraulic cylinder 51, and inner support rod 54 and inner support clamp 55 are kept in an open state, so that thin-walled tube is fixed in fixed cylinder 4; rotating disk 3 is driven by drive component 6 to realize continuous processing of blind hole.

[0030] Specifically, the side wall of the rotating disk 3 is provided with a sliding groove 57, and the end of the inner support clamp 55 is provided with a slider 58 that matches the sliding groove 57. When the hydraulic cylinder 51 drives the drive rod 52 to move towards the rotating disk 3, the inner support rod 54 pushes the inner support clamp 55 to open through the hinge point. At this time, the slider 58 slides along the sliding groove 57 to ensure that the opening action of the inner support clamp 55 is carried out in the radial or circumferential direction of the rotating disk 3. The guiding effect of the sliding groove 57 can evenly distribute the clamping force and avoid excessive local pressure caused by uneven force on the inner support clamp 55, thereby protecting the inner wall of the thin-walled pipe from being scratched or deformed.

[0031] Specifically, the drive assembly 6 includes a worm gear 61 mounted on the rotating disk 3, a worm 62 adapted to the worm gear 61 rotatably mounted on the worktable 1, and a drive motor 63 for driving the worm 62 to rotate on the worktable 1. After the drive motor 63 starts, it drives the worm 62 to rotate, and the worm 62 meshes with the worm gear 61, transmitting the rotational motion to the worm gear 61. The worm gear 61 drives the rotating disk 3 to rotate synchronously, thereby driving the fixed cylinder 4 and the clamped thin-walled tube to rotate. The worm gear transmission has a unidirectional transmission characteristic. When the worm 62 stops rotating, the worm gear 61 cannot drive the worm 62 in the reverse direction due to friction, thus preventing the rotating disk 3 from rotating in the reverse direction due to external force during processing. Through the self-locking performance of the worm gear in the drive assembly 6, combined with the auxiliary support of the support structure 7, the rotating disk 3 can rotate smoothly, reducing the impact of vibration on processing accuracy and ensuring the accuracy of the blind hole position dimensions.

[0032] Specifically, the support structure 7 includes a groove 71 set on the workbench 1. An electric cylinder 72 is provided at the bottom of the groove 71. A lifting seat 73 is provided at the output end of the electric cylinder 72. Two support rollers 74 adapted to the fixed cylinder 4 are provided on the lifting seat 73. In the initial state, the electric cylinder 72 is in the retracted state, the lifting seat 73 is located at the bottom of the groove 71, and the support rollers 74 are kept at a certain distance from the fixed cylinder 4 to facilitate the installation of thin-walled pipe fittings. After the thin-walled pipe fittings are installed, the electric cylinder 72 is activated to extend and drive the lifting seat 73 to move upward, so that the support rollers 74 contact the end of the fixed cylinder 4. The support rollers 74 support the fixed cylinder 4 through rolling friction, reducing the vibration and displacement caused by its rotation.

[0033] Working Principle: During operation, the thin-walled perforator fitting is placed inside the fixed cylinder 4. The hydraulic cylinder 51 is activated, driving the rod 52 to move towards the rotating disk 3, causing the inner support rod 54 to rotate around the hinge point. The inner support rod 54 pushes the inner support clamp 55 to open, and the anti-slip pad 56 adheres tightly to the inner wall of the fitting, applying clamping force evenly through multi-point contact when processing blind holes. After the drive motor 63 starts, it drives the worm wheel 61 to rotate via the worm gear 62. The worm wheel 61 is fixedly connected to the rotating disk 3, causing the rotating disk 3 and the fixed cylinder 4 to rotate synchronously. Simultaneously, the electric cylinder 72 drives the lifting seat 73 to move upward, causing the support roller 74 to contact the end of the fixed cylinder 4. After processing is complete, the hydraulic cylinder 51 retracts, and the inner support clamp 55 resets, releasing the inner wall of the fitting. After the rotating disk 3 stops rotating, the support roller 74 descends, the fixed cylinder 4 disengages from the support structure, and the operator can remove the processed thin-walled perforator fitting.
