Abstract
Description
Technical Field
[0001] This invention relates to the field of downhole tool processing technology for oil and gas wells, and particularly to a cutting device for processing slips. Background Technology
[0002] Packers are key tools used in downhole operations of oil and gas wells. Their main function is to seal off different sections within the wellbore to prevent fluid or pressure from flowing between layers, thereby enabling core operations such as layered production, layered water injection, fracturing, and acidizing. They are widely used in drilling, completion, and repair engineering of oil and gas. By sealing the annular space between the tubing and casing, they ensure that each production layer operates independently, improving oil production efficiency and protecting the wellbore structure.
[0003] During the packer installation and sealing process, the slips are the core components that enable the packer to be mechanically anchored inside the casing and prevent it from moving up and down. They are crucial for ensuring the long-term stable sealing of the packer and for it to play its role as a sealing layer. Currently, the processing of slips involves cutting toothed grooves into the outside of a smooth cylindrical rod, and then using cutting equipment to divide the toothed rod into several (eight) independent slip units.
[0004] In the traditional processing of packer core component slips, the cutting process has long relied on manual operation. After each slip is cut, the entire rod needs to be manually rotated and adjusted to a preset angle before the next slip is cut. This manual intervention lengthens the overall processing cycle and is difficult to adapt to the pace of large-scale production. Especially in the processing of high-hardness alloy slips, the alternating operation of cutting and manual adjustment further amplifies the efficiency shortcomings. Therefore, we propose a cutting device for slip processing. Summary of the Invention
[0005] The purpose of this invention is to provide a cutting device for chuck processing. By integrating an automatic indexing and rotating mechanism, the device can achieve precise angle positioning of the cutting station. After completing the cutting process of a single chuck unit, the device can automatically drive the blank to rotate to the preset next cutting angle, and can continuously complete the cutting operations of multiple sets of chuck units without manual intervention.
[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a cutting device for machining slips, comprising a frame, a band saw sliding on the frame, a base plate mounted on the frame, a mounting plate slidably mounted on the base plate, and a cylinder mounted on the base plate. The output end of the cylinder is connected to the mounting plate. Two side plates are symmetrically arranged on the mounting plate, and two sawing grooves are formed on the side plates. A fixing component is provided on one side plate, and a rotating component is provided on the other side plate. Two sets of transmission components are symmetrically rotatably connected between the two side plates. The transmission components are driven by the rotating components through belts. Two sets of compensable limiting components are symmetrically arranged on the mounting plate, and a pushing component with one end connected to the limiting component is slidably mounted on the limiting component.
[0007] By adopting the above technical solution, the blank to be cut is fixed between the two side plates by the fixing component, so that the two ends of the blank are close to the fixing component and the rotating component respectively. Then, the limiting components on the front and rear sides are pressed against the outside of the blank. The band saw moves down and completes a sawing on the blank through the sawing groove. After the band saw is reset, the cylinder pushes the mounting plate and the blank to move. The band saw moves down again to perform a second sawing on the blank, thereby realizing the segmentation processing of a single clamp. During the sawing process, the limiting component can limit and constrain the blank from the front and rear sides, effectively ensuring the sawing accuracy and avoiding deviation in the sawing position.
[0008] When cutting the next clamp, the rotating component starts and drives the remaining blank to rotate 45 degrees. During the rotation, the fixing component always keeps the blank axially fixed. At the same time, the rotating component rotates through the belt drive component. Every time the rotating component rotates 45 degrees, the drive component drives the push component to complete one reciprocating movement operation. This ensures that the limit component separates from the blank and does not obstruct its rotation. After rotating to the preset angle, the limit component re-clamps against the blank, thereby preventing the blank from shifting during subsequent cutting. Every 45 degrees of rotation, the rotating component automatically triggers the push component and limit component to operate. Indexing, clearance, and clamping are completed automatically in one integrated process, which can be used for continuous processing and improves processing efficiency.
[0009] When a single blank is divided multiple times, and the arc length of the remaining blank is less than its diameter, the compensation function of the limiting component can be used to make adaptive adjustments after the limiting component is reset, so that it can still effectively limit and clamp the remaining blank from both the front and rear sides, thereby continuously ensuring the sawing accuracy of the blank.
[0010] A further configuration of the present invention is as follows: the fixing component includes a lead screw that passes through and is threadedly connected to the corresponding side plate, a rotating handle mounted on the lead screw, a limiting plate that is slidably connected to the mounting plate, and a fixing plate rotatably connected to the other side of the limiting plate, wherein the limiting plate is rotatably connected to the other side of the lead screw.
[0011] By adopting the above technical solution, the rotating handle drives the lead screw to rotate. Under the threaded engagement between the lead screw and the side plate, the lead screw pushes the limiting plate to move linearly along the mounting plate. The limiting plate then drives the fixing plate to move towards the blank, so that the fixing plate presses against the end face of the blank, thereby achieving axial fixation of the blank. During the process of the blank being driven to rotate by the rotating component, the fixing plate can rotate freely relative to the limiting plate. Thus, while maintaining axial pressing against the blank, it does not affect the normal rotation of the blank, ensuring that the blank maintains a stable and reliable positioning state during sawing and indexing rotation.
[0012] A further configuration of the present invention is as follows: the rotating assembly includes a rotating shaft passing through and rotatably connected to the corresponding side plate, a fixed plate connected to one side of the rotating shaft, and a pulley mounted on the corresponding side plate; the output shaft of the rotating motor is fixedly connected to the rotating shaft; and a pulley is also mounted on the rotating shaft.
[0013] By adopting the above technical solution, after the rotating motor starts, its output shaft drives the rotating shaft to rotate around its own axis. The rotating shaft simultaneously drives the fixed plate two and the pulley one on it to rotate synchronously. The fixed plate two drives the blank clamped by the fixed component to rotate together through the friction with the end face of the blank, realizing the indexing of the blank (45 degrees each time). At the same time, the pulley one drives the transmission component to rotate through the belt, thereby driving the push component to complete one reciprocating movement, so that the limiting component is separated from the blank, avoiding interference with the rotation of the blank.
[0014] When the rotating motor stops, the rotating shaft, the second fixed plate, and the first pulley stop rotating synchronously, and the blank is positioned at the preset angle. At this time, the limiting component re-clamps against the blank. Throughout the process, the rotational connection between the rotating shaft and the side plate ensures the smoothness of the rotation. The rotating motor achieves precise control of the indexing angle, and the first pulley achieves synchronous power transmission, ultimately realizing the precise indexing rotation of the blank and providing a reliable guarantee for the continuous division of the clamp.
[0015] A further feature of the present invention is that the transmission assembly includes a transmission rod installed through and rotatably connected to the two side plates. Two transmission rods are symmetrically arranged. A second pulley and a transmission wheel are installed on the transmission rod. A belt is connected between the second pulley and the first pulley. Eight equally divided plum blossom-shaped circumferential positioning grooves are evenly opened on the end face of the transmission wheel along the circumferential direction.
[0016] A further feature of the present invention is that the positioning groove is composed of eight consecutive limiting tooth grooves connected end to end, the included angle between the centers of adjacent limiting tooth grooves is 45 degrees, and the limiting tooth groove is composed of an outwardly convex arc segment and an inwardly concave arc segment connected together.
[0017] A further configuration of the present invention is that the pushing assembly includes a U-shaped rod connected to the limiting plate and a pushing connecting rod mounted on the U-shaped rod, one end of the pushing connecting rod extending through a guide post into the limiting tooth groove and sliding within the groove.
[0018] A further feature of the present invention is that each time the transmission wheel achieves a 45-degree intermittent indexing rotation, the guide contour of its limiting tooth groove causes the push link to complete a linear reciprocating stroke in the corresponding groove, and then the motion is transmitted by the U-shaped rod, so that the limiting plate on the limiting plate performs a complete reciprocating movement operation.
[0019] By adopting the above technical solution, after the rotating motor starts, its output shaft drives the rotating shaft to rotate around its own axis. The rotating shaft simultaneously drives the fixed plate two and the pulley one on it to rotate synchronously. The fixed plate two drives the blank clamped by the fixed component to rotate together through the friction with the end face of the blank, realizing the 45-degree indexing rotation of the blank. At the same time, the pulley one drives the pulley two of the transmission component to rotate synchronously through the belt. The pulley two drives the transmission rod and the transmission wheel to rotate synchronously in 45-degree intermittent indexing.
[0020] When the drive wheel rotates, the contour of the upper limit tooth groove on its end face guides the guide post of the push rod to slide linearly back and forth, so that the push rod completes one linear back and forth stroke. The movement of the push rod is transmitted to the limit plate through the U-shaped rod, which drives the limit plate on the limit plate to perform a complete reciprocating movement operation. That is, in the initial stage of the drive wheel rotation, the guide post slides along the outer convex arc section of the limit tooth groove, pushes the push rod to extend, and the U-shaped rod drives the limit plate away from the blank to avoid the blank from rotating. After the drive wheel completes a 45-degree rotation, the guide post slides along the inner concave arc section of the limit tooth groove, pushes the push rod to retract, and the U-shaped rod drives the limit plate to reset and re-press against the blank, so as to achieve precise positioning of the blank.
[0021] When the rotating motor stops, the rotating shaft, fixed plate two, pulley one, transmission components, and push components stop moving synchronously. The blank is positioned at the preset sawing angle, and the limiting plate remains in a tight position, providing a stable positioning guarantee for the sawing of the clamp. Throughout the entire linkage process, the actions of each component are precise and synchronized. The rotating component is responsible for blank indexing, the transmission component is responsible for power transmission and angle matching, and the push component is responsible for driving the limiting component to complete avoidance and reset. The three work together to achieve continuous and precise indexing and positioning of the blank, providing reliable support for the efficient and high-quality cutting of the clamp.
[0022] A further feature of the present invention is that the limiting assembly includes a limiting plate slidably mounted on the mounting plate. Two limiting plates are symmetrically arranged and located on the front and rear sides of the first fixing plate and the second fixing plate. A screw is threadedly connected to the limiting plate, and a limiting abutment is rotatably connected to the screw. A guide rod penetrating the limiting plate is installed on the limiting abutment.
[0023] By adopting the above technical solution, the screw moves linearly along the threaded hole of the limiting plate, driving the limiting abutment to move along the guide direction of the guide rod until the limiting abutment is tightly attached to the surface of the blank, achieving precise limiting. The guide rod ensures that the limiting abutment does not deviate during the movement, and the screw's thread self-locking property keeps the limiting abutment in the compensated position, avoiding vibration displacement. When a single blank is divided multiple times and the arc length of the remaining blank is less than its diameter, the compensation function of the limiting component can be used to adaptively adjust after the limiting component is reset, so that it can still effectively limit and clamp the remaining blank from both the front and rear sides, thereby continuously ensuring the sawing accuracy of the blank.
[0024] A further feature of the present invention is that: a protective cover is provided on the outer side of the pulley and the belt, and the rotating motor is fixed to the corresponding side plate through the protective cover. Both sides of the top of the protective cover are sloped.
[0025] By adopting the above technical solution, the protective cover can protect the transmission between the two pulleys and the belt, preventing transmission jamming. When the saw blade on the band saw passes through the sawing groove, it will not interfere with the protective cover.
[0026] A further feature of the present invention is that the frame is also provided with a drive source for driving the band saw to slide up and down.
[0027] The beneficial effects of this invention are:
[0028] 1. When cutting the next clamp, the rotating component starts and drives the remaining blank to rotate 45 degrees. During the rotation, the fixing component always keeps the blank axially fixed. At the same time, the rotating component rotates through the belt drive component. Every time the rotating component rotates 45 degrees, the drive component drives the push component to complete one reciprocating movement operation. This ensures that when the blank is rotating, the limiting component separates from the blank and does not obstruct its rotation. After rotating to the preset angle, the limiting component re-clamps against the blank, thereby preventing the blank from shifting during subsequent cutting.
[0029] 2. Throughout the entire linkage process, the actions of each component are precisely synchronized. The rotating component is responsible for the blank indexing, the transmission component is responsible for power transmission and angle matching, and the pushing component is responsible for driving the limiting component to complete avoidance and reset. The three work together to achieve continuous and accurate indexing and positioning of the blank, providing reliable support for the efficient and high-quality segmentation of the clapper.
[0030] 3. When the arc length of the remaining blank is less than its diameter after a single blank has been divided multiple times, the compensation function of the limiting component can be used to make adaptive adjustments after the limiting component is reset, so that it can still effectively limit and clamp the remaining blank from the front and rear sides, thereby continuously ensuring the sawing accuracy of the blank.

[0038] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0039] Please see Figure 1-5This invention provides a cutting device for processing clamps, including a frame 1, a band saw 2 sliding on the frame 1, a base plate 3 mounted on the frame 1, a mounting plate 4 slidably mounted on the base plate 1, and a cylinder 5 mounted on the base plate 3. The output end of the cylinder 5 is connected to the mounting plate 4. Two side plates 6 are symmetrically arranged on the mounting plate 4, and two sawing grooves 7 are formed on the side plates 6. A fixing component 8 is provided on one side plate 6, and a rotating component 9 is provided on the other side plate 6. Two sets of transmission components 10 are symmetrically rotatably connected between the two side plates 6. The transmission components 10 are driven by the rotating components 9 through a belt 11. Two sets of compensable limiting components 13 are symmetrically arranged on the mounting plate 4. A pushing component 14 with one end connected to the limiting component 10 is slidably mounted on the limiting component 13.
[0040] The blank to be cut is fixed between the two side plates 6 by the fixing component 8, so that both ends of the blank are close to the fixing component 8 and the rotating component 9 respectively. Then, the limiting components 13 on the front and rear sides are pressed against the outside of the blank. The band saw 2 moves down and completes a sawing on the blank through the sawing groove 7. After the band saw 2 is reset, the cylinder 5 pushes the mounting plate 4 and the blank to move. The band saw 2 moves down again to perform a second sawing on the blank, thereby realizing the segmentation processing of a single clamp. During the sawing process, the limiting component 13 can limit and constrain the blank from the front and rear sides, effectively ensuring the sawing accuracy and avoiding deviation in the sawing position.
[0041] When cutting the next clamp, the rotating component 9 starts and drives the remaining blank to rotate 45 degrees. During the rotation, the fixing component 8 always keeps the blank axially fixed. At the same time, the rotating component 9 drives the transmission component 10 to rotate through the belt 11. Every time the rotating component 9 rotates 45 degrees, the transmission component 10 drives the pushing component 14 to complete one reciprocating movement operation, ensuring that the limiting component 13 does not block the rotation of the blank when it is rotating. After rotating to the preset angle, the limiting component 13 is pressed against the blank again, thereby preventing the blank from shifting during subsequent cutting. Every time the rotating component 9 rotates 45 degrees, it automatically triggers the pushing component 14 and the limiting component 13 to move. Indexing, displacement and clamping are completed automatically in one integrated process, which can be continuously processed and improves processing efficiency.
[0042] When a single blank is divided multiple times, and the arc length of the remaining blank is less than its diameter, the compensation function of the limiting component 13 can be used to make adaptive adjustments after the limiting component 13 is reset, so that it can still effectively limit and clamp the remaining blank from the front and rear sides, thereby continuously ensuring the sawing accuracy of the blank.
[0043] The fixing component 8 includes a lead screw 81 that passes through and is threadedly connected to the corresponding side plate 6, a rotating handle 82 mounted on the lead screw 81, a limiting plate 83 slidably connected to the mounting plate 4, and a fixing plate 84 rotatably connected to the other side of the limiting plate 83. The limiting plate 83 is rotatably connected to the other side of the lead screw 81. Operating the rotating handle 82 drives the lead screw 81 to rotate. Under the threaded engagement between the lead screw 81 and the side plate 6, the lead screw 81 pushes the limiting plate 83 to move linearly along the mounting plate 4. The limiting plate 83 then drives the fixing plate 84 to move towards the blank, so that the fixing plate 84 presses against the end face of the blank, thereby achieving axial fixation of the blank. During the process of the blank being driven to rotate by the rotating component 9, the fixing plate 84 can rotate freely relative to the limiting plate 83, so as to maintain axial pressing against the blank without affecting the normal rotation of the blank, ensuring that the blank maintains a stable and reliable positioning state during sawing and indexing rotation.
[0044] The rotating assembly 9 includes a rotating shaft 91 that passes through and is rotatably connected to the corresponding side plate 6, a second fixed plate 92 connected to one side of the rotating shaft 91, and a belt pulley 94 mounted on the corresponding side plate 6. The output shaft of the rotating motor 93 is fixedly connected to the rotating shaft 91. A belt pulley 94 is also mounted on the rotating shaft 91. After the rotating motor 93 starts, its output shaft drives the rotating shaft 91 to rotate around its own axis. The rotating shaft 91 simultaneously drives the second fixed plate 92 and the belt pulley 94 to rotate synchronously. The second fixed plate 92, through friction with the end face of the blank, drives the blank clamped by the fixing assembly 8 to rotate together, realizing the indexing of the blank (rotating 45 degrees each time). At the same time, the belt pulley... The first wheel 94 drives the transmission component 10 to rotate via the belt 11, which in turn drives the push component 14 to complete one reciprocating movement, separating the limiting component 13 from the blank and avoiding interference with the blank's rotation. When the rotating motor 93 stops, the rotating shaft 91, the second fixed plate 92, and the first pulley 94 stop rotating synchronously, and the blank is positioned at a preset angle. At this time, the limiting component 13 re-clamps against the blank. Throughout the process, the rotational connection between the rotating shaft 91 and the side plate 6 ensures the smoothness of the rotation. The rotating motor 93 achieves precise control of the indexing angle, and the first pulley 94 achieves synchronous power transmission, ultimately realizing the precise indexing rotation of the blank and providing a reliable guarantee for the continuous division of the clamp.
[0045] The transmission assembly 10 includes a transmission rod 101 that is mounted through and rotatably connected to the two side plates 6. Two transmission rods 101 are symmetrically arranged. A second pulley 102 and a transmission wheel 103 are mounted on the transmission rod 101. A belt 11 is connected between the second pulley 102 and the first pulley 94. Eight equally divided plum blossom-shaped circumferential positioning grooves 104 are evenly opened on the end face of the transmission wheel 103 along the circumferential direction. The positioning grooves 104 are formed by eight continuous limiting tooth grooves 1041 connected end to end. The included angle between the centers of adjacent limiting tooth grooves 1041 is 45 degrees. The limiting tooth grooves 1041 consist of an outwardly convex arc segment and an inner arc segment. The concave arc segment is connected. The pushing component 14 includes a U-shaped rod 141 connected to the limiting plate 131 and a pushing connecting rod 142 installed on the U-shaped rod 141. One end of the pushing connecting rod 142 extends into the limiting tooth groove through the guide post and slides in the groove. Each time the transmission wheel 103 achieves a 45-degree intermittent indexing rotation, the pushing connecting rod 142 completes a linear reciprocating stroke in the corresponding groove through the guide contour of its limiting tooth groove 1041. Then, the motion is transmitted by the U-shaped rod 141, so that the limiting abutment plate 132 on the limiting plate 131 performs a complete reciprocating movement operation.
[0046] After the rotating motor 93 starts, its output shaft drives the rotating shaft 91 to rotate around its own axis. The rotating shaft 91 simultaneously drives the fixed plate 92 and the pulley 94 on it to rotate synchronously. The fixed plate 92 drives the blank clamped by the fixed component 8 to rotate together through the friction with the end face of the blank, realizing the 45-degree indexing rotation of the blank. At the same time, the pulley 94 drives the pulley 102 of the transmission component 10 to rotate synchronously through the belt 11. The pulley 102 drives the transmission rod 101 and the transmission wheel 103 to rotate synchronously in 45-degree intermittent indexing.
[0047] When the transmission wheel 103 rotates, the contour of the upper limit groove 1041 on its end face guides the guide post of the push rod 142 to slide linearly back and forth, so that the push rod 142 completes one linear back and forth stroke. The movement of the push rod 142 is transmitted to the limiting plate 131 through the U-shaped rod 141, which drives the limiting plate 132 on the limiting plate 131 to perform one complete reciprocating movement operation. That is, at the beginning of the rotation of the transmission wheel 103, the guide post slides along the outer convex arc section of the limiting groove 1041, pushing the push rod 142 to extend. The U-shaped rod 141 drives the limiting plate 132 away from the blank, avoiding the rotation of the blank. After the transmission wheel 103 completes a 45-degree rotation, the guide post slides along the inner concave arc section of the limiting groove 1041, pushing the push rod 142 to retract. The U-shaped rod 141 drives the limiting plate 132 to reset and re-press against the blank, realizing the precise positioning of the blank.
[0048] When the rotating motor 93 stops, the rotating shaft 91, the fixed plate 92, the pulley 94, the transmission assembly 10, and the pushing assembly 14 stop moving synchronously. The blank is positioned at the preset sawing angle, and the limiting plate 132 remains in a tight position, providing a stable positioning guarantee for the sawing of the clamp. During the entire linkage process, the actions of each component are precise and synchronized. The rotating assembly 9 is responsible for blank indexing, the transmission assembly 10 is responsible for power transmission and angle matching, and the pushing assembly 10 is responsible for driving the limiting assembly 13 to complete avoidance and reset. The three work together to achieve continuous and precise indexing and positioning of the blank, providing reliable support for the efficient and high-quality cutting of the clamp.
[0049] The limiting assembly 13 includes a limiting plate 131 slidably mounted on the mounting plate 4. Two limiting plates 131 are symmetrically arranged on the front and rear sides of the first fixing plate 84 and the second fixing plate 92. A screw 132 is threadedly connected to the limiting plate 131, and a limiting abutment 133 is rotatably connected to the screw 132. A guide rod 134 is mounted on the limiting abutment 133, penetrating the limiting plate 131. The screw 132 moves linearly along the threaded hole of the limiting plate 131, causing the limiting abutment 133 to move along the guiding direction of the guide rod 134. The limiting plate 133 fits tightly against the surface of the blank to achieve precise positioning. The guide rod 134 ensures that the limiting plate 133 does not deviate during movement. The thread self-locking property of the screw 132 keeps the limiting plate 133 in the compensated position to avoid vibration displacement. When a single blank is divided multiple times and the arc length of the remaining blank is less than its diameter, the compensation function of the limiting component 13 can be used to make adaptive adjustments after the limiting component 13 is reset, so that it can still effectively limit and clamp the remaining blank from the front and rear sides, thereby continuously ensuring the sawing accuracy of the blank.
[0050] In practical use, the transmission wheels 103 on a single transmission rod 101 can be symmetrically arranged to improve the stability of motion transmission.
[0051] The outer side of the pulley 102 and the belt 11 is provided with a protective cover 12. The rotating motor 12 is fixed to the corresponding side plate 6 through the protective cover 12. Both sides of the top of the protective cover 12 are set as inclined surfaces. The protective cover 12 can protect the transmission between the pulley 102 and the belt 11 and prevent transmission jamming. When the saw blade on the band saw 2 passes through the sawing groove 7, it will not interfere with the protective cover 12.
[0052] The frame 1 is also provided with a drive source for driving the band saw 2 to slide up and down. The drive source adopts conventional existing technology in the field. Its specific structure, connection method and working principle are common knowledge to those skilled in the art. It will not be described in detail in this application. It is only necessary to clarify that it realizes the function of the band saw 2 sliding up and down.
[0053] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
