Description

Technical Field

[0001] The present application relates to the technical field of sucker rod processing, and in particular to a sucker rod external thread processing device. Background Art

[0002] In the oil extraction industry, the sucker rod is one of the key equipment, and its quality and performance are directly related to the production efficiency and safety of the oil well. Especially in the manufacturing process of the sucker rod, the processing quality of the external thread is crucial, which directly affects the connection tightness and sealing between the sucker rod and other parts of the oil well. However, with the advancement of science and technology and the improvement of the level of industrial automation, the demand for automated and intelligent processing equipment in the machinery manufacturing industry is becoming increasingly urgent. Especially in the field of oil equipment manufacturing, in order to improve the production efficiency and processing quality of the sucker rod, the development of an efficient and accurate automatic processing device for the external thread of the sucker rod has become an urgent need in the industry.

[0003] The existing technology still has the following problems:

[0004] 1. When processing the external thread of the sucker rod, the sucker rod needs to be clamped and rotated at the same time so as to perform thread milling on the sucker rod. The existing clamping assembly cannot be rotated after being clamped and fixed, which is easy to cause position deviation during the clamping process. The shaking will cause the relative position between the milling cutter and the sucker rod to be unstable, thereby affecting the accuracy and consistency of the thread. In addition, it is difficult to detect the shaking of the sucker rod position during the thread milling process in time, which leads to defective products in the production process and reduces the sealing and wear resistance of the sucker rod threaded connection.

[0005] 2. When milling the sucker rod, due to the different specifications of the sucker rod, the distance between the milling tool and the sucker rod changes, and different tools need to be replaced for milling. Even when the sucker rods of the same specifications are processed, the milling depth cannot be adjusted according to the needs, which leads to great limitations of the sucker rod processing equipment.

[0006] 3. The existing sucker rod external thread processing device cannot clean up the debris generated during milling in time. The cutting debris adheres to the outer surface of the sucker rod, which will change its actual size and shape, resulting in changes in the matching clearance between the milling tool, thereby affecting the accuracy of the thread. The hard particles in the cutting debris may scratch or wear the tool surface, shorten the service life of the tool, and even cause personal safety. In addition, the use of vessels to handle the debris is prone to accumulation, and the debris is easy to enter the equipment during the rotation and milling movement of the sucker rod, which may cause mechanical failure.

[0018] The technical solution provided by this application has at least the following technical effects or advantages:

[0019] 1. The use of a clamping assembly effectively solves the problem of needing to clamp the sucker rod when processing the external thread of the sucker rod, and at the same time, needing to rotate the sucker rod so as to perform thread milling on the sucker rod. The existing clamping assembly cannot be clamped and fixed, and is prone to positional displacement during the clamping process. Shaking will cause the relative position between the milling cutter and the sucker rod to be unstable, thereby affecting the accuracy and consistency of the thread. In addition, it is difficult to detect in time if the position of the sucker rod shakes during the thread milling process, which leads to defective products in the production process and reduces the sealing and wear resistance of the sucker rod threaded connection. The present invention can limit the sucker rod through the clamping assembly and ensure that the sucker rod can rotate on the clamping assembly, so that the relative position between the milling cutter and the sucker rod is stable, the accuracy and consistency of the thread are maintained, and an alarm can be issued when the sucker rod is displaced under the action of external force, thereby avoiding defective products in the production process and improving the sealing and wear resistance of the sucker rod threaded connection.

[0020] 2. The use of a processing assembly effectively solves the problem that when milling sucker rods, the distance between the milling tool and the sucker rod changes due to the different specifications of the sucker rods, and different tools need to be replaced for milling. Even when the sucker rods of the same specification are processed, the milling depth cannot be adjusted as required, which leads to large limitations of the sucker rod processing equipment. The present invention can adjust the position of the milling tool according to the specifications of the sucker rod through the processing assembly, which is convenient for adjusting the milling tool according to the specifications of the threaded rod and the depth of thread milling, avoiding the need to replace the milling tool when processing sucker rods of different specifications, and improving the fault tolerance of the milling tool thread processing.

[0021] 3. The use of a dust removal component effectively solves the problem that the existing sucker rod external thread processing device is unable to clean up the debris generated during milling in time. The cutting debris adheres to the outer surface of the sucker rod, which will change its actual size and shape, resulting in a change in the matching clearance between the milling tool and the milling tool, thereby affecting the accuracy of the thread. The hard particles in the cutting debris may scratch or wear the tool surface, shorten the service life of the tool, and even cause personal safety. In addition, the use of containers to hold the debris is prone to accumulation, and the debris is likely to enter the equipment during the rotation of the sucker rod and the milling movement, which may cause mechanical failure. The present invention can timely clean up the debris generated during milling through the dust removal component, and can perform real-time chip removal according to the movement of the milling tool. The debris will not accumulate and overflow, preventing the debris from splashing everywhere, avoiding the cutting debris from adhering to the outer surface of the sucker rod to affect the accuracy of the thread, preventing the hard particles in the cutting debris from scratching or wearing the tool surface, thereby increasing the service life of the tool and ensuring the personal safety of the user.

[0046] Embodiment 2:

[0047] See also Fig.11and Fig.12 As shown, the dust removal assembly 7 includes a dust collecting box 71, and a dust guide rod 72 is fixedly installed in the inner cavity of the dust collecting box 71. The cross section of the dust guide rod 72 is a semicircle, and the bottom surface is a parallel surface. The dust guide rod 72 is evenly distributed on the inner wall of the dust collecting box 71. The inner cavity of the dust collecting box 71 is slidably connected with a dust removal mechanism 73. The inner cavity of the dust collecting box 71 is provided with a dust collection mechanism 74. The dust collecting box 71 is slidably connected to the fixed frame 661. The dust collecting box 71 can slide up and down on the outer surface of the fixed frame 661, so as to drive the dust removal mechanism 73 to rise and fall when the lifting platform 65 rises and falls. At this time, the dust collecting box 71 slides on the fixed frame 661 to maintain the overall stability of the dust removal assembly 7. The dust collecting box 71 is used to collect the debris generated during milling. The dust guiding rod 72 facilitates guidance and prevents the debris entering the inner cavity of the dust collecting box 71 from splashing out again. The dust removal mechanism 73 is used to discharge the debris generated during the milling of the milling tool 64 and the sucker rod processing part 4. Finally, the debris enters the dust collecting mechanism 74 for collection and centralized discharge, preventing the debris from affecting the milling of the sucker rod processing part 4 and avoiding the debris from contaminating the equipment.

[0048] See also Fig.11 and Fig.12 As shown, the dust removal mechanism 73 includes a movable frame 731, a connecting block 732 is fixedly installed on the upper surface of the movable frame 731, the connecting block 732 and the milling tool 64 are fixedly connected, a dust removal scraping strip 733 is fixedly installed on the outer surface of the movable frame 731, the dust removal scraping strip 733 and the dust collecting box 71 are slidably connected, the dust removal scraping strip 733 and the upper surface of the dust guide rod 72 are tightly fitted, the dust removal scraping strip 733 and the dust guide rod 72 are slidably connected, the top of the movable frame 731 is rotatably connected with a rotating block 734, and a fan 735 is provided on the outer surface of the rotating block 734. The fan 735 is located above the milling tool 64, so that the fan 735 can always blow off the debris generated by the milling of the milling tool 64 during the movement of the milling tool 64, and the angle of the fan 735 is adjusted so that the wind blown by the fan 735 is aligned between the milling tool 64 and the sucker rod processing part 4. The movable frame 731 and the lifting platform 65 slide The connection block 732 is dynamically connected. When the milling tool 64 moves, the connection block 732 moves, and the connection block 732 moves to drive the moving frame 731 to slide in the inner cavity of the lifting platform 65. The movement of the moving frame 731 drives the rotating block 734 to move. The movement of the rotating block 734 drives the fan 735 to move. When the milling tool 64 is milling, the fan 735 can blow off the debris generated by milling, so that the debris is on the dust box 71, and the dust is guided by the dust guide rod 72. After the debris enters the inner cavity of the dust collecting box 71, the debris will not overflow from the inner cavity of the dust collecting box 71 due to the obstruction of the dust guiding rod 72. At the same time, the movement of the movable frame 731 drives the dust removing scraping strip 733 to move. The movement of the dust removing scraping strip 733 enables the dust removing scraping strip 733 to scrape off the debris on the outer surface of the dust guiding rod 72, making it easier for the debris to enter the inner cavity of the dust collecting box 71, thereby keeping the outer surface of the dust guiding rod 72 relatively clean and preventing the debris from being blocked and affecting the debris from entering the inner cavity of the dust collecting box 71.

A connecting box 743 is provided on the upper surface of the dust collecting box 741. A clamping rod 744 is slidably connected to the inner wall of the connecting box 743. The clamping rod 744 and the clamping block 742 are slidably connected. The dust collecting box 741 and the connecting box 743 are connected by the clamping block 742 and the clamping rod 744. A push rod 745 is fixedly installed on the upper surface of the connecting box 743. A hand lever 746 is fixedly installed on the bottom end of the dust collecting box 741. The four corners of the dust collecting box 71 are fixed A second limiting rod 747 is fixedly installed, and a third spring 748 is sleeved on the outer surface of the second limiting rod 747. The third spring 748 is located between the inner wall of the dust collecting box 71 and the connecting box 743. The dust collecting box 741 and the connecting box 743 are both slidably connected to the dust collecting box 71. The dust collecting box 71 is located just below one end of the sucker rod processing part 4. After the debris enters the dust collecting box 71, it eventually falls on the dust collecting box 741 for centralized collection. As the amount of debris increases, the dust collecting box 741 drives the connecting box 743 to move downward, and the downward movement of the connecting box 743 drives the connecting box 743 to move downward. When the second limit rod 747 slides on the second limit rod 747, the third spring 748 is compressed to make the bottom end of the dust box 741 gradually protrude from under the dust box 71 until the bottom end of the connecting box 743 is flush with the lower surface of the dust box 71. At this time, the hand lever 746 can be pulled to disengage the block 742 from the clamping rod 744, thereby facilitating the removal of the debris on the dust box 741. At the same time, when the weight of the debris is not enough to expose the bottom end of the connecting box 743, the connecting box 743 can be pressed down by pressing the push rod 745, and then the dust box 741 can be taken out. The debris will be cleaned up, and after cleaning, the connecting box 743 is exposed on the lower surface of the dust collecting box 71 by pressing the push rod 745. At this time, the block 742 and the clamping rod 744 are engaged again, and the push rod 745 is released. Under the elastic force of the third spring 748, the dust collecting box 741 slides on the inner cavity of the dust collecting box 71, and the debris is collected again to prevent the debris from splashing everywhere, and to prevent the cutting debris from adhering to the outer surface of the sucker rod and affecting the accuracy of the thread, and to prevent the hard particles in the cutting debris from scratching or wearing the tool surface, thereby increasing the service life of the tool and ensuring the personal safety of the user.

The limiting mechanism 57 is used to tighten the flexible strength of the slide plate 52 on the first connecting seat 51. The alarm mechanism 58 is used to sound an alarm when the slide plate 52 shakes to prevent the sucker rod processing part 4 from being displaced, resulting in uneven milling of the sucker rod thread. The fifth threaded rod 63 is driven to rotate by the work of the third motor 68. The rotation of the fifth threaded rod 63 drives the milling tool 64 to slide on the distance adjustment frame 62, and the milling tool The tool 64 moves and cooperates with the rotating seat 2 to rotate to mill the sucker rod processing part 4, so that the sucker rod processing part 4 produces an external thread, and the lifting mechanism 66 drives the lifting platform 65 to lift and lower, and the distance adjustment mechanism 67 drives the milling tool 64 to change the distance from the sucker rod processing part 4, so that the distance between the milling tool 64 and the sucker rod processing part 4 can be adjusted according to the specifications of the sucker rod processing part 4. At the same time, the milling depth of the sucker rod processing part 4 can be adjusted, and the dust box 71 can slide up and down on the outer surface of the fixed frame 661, so that it is convenient to drive the lifting platform 65 to lift and lower. The dust removal mechanism 73 is raised and lowered, and at this time, the dust box 71 slides on the fixed frame 661 to maintain the overall stability of the dust removal assembly 7. The dust box 71 is used to collect debris generated during milling.
