Description

Technical Field

[0001] This invention relates to the field of centralizer processing technology, and in particular to a centralizer processing and forming apparatus for oil extraction. Background Technology

[0002] In the drilling process of oil extraction, the sucker rod, as a key oil production device, undertakes the important task of transporting crude oil from the well to the surface. However, during the oil extraction process, direct contact between the sucker rod and the inner wall of the tubing is inevitable. This contact leads to a large frictional force between the two. Long-term friction not only accelerates the wear of the sucker rod and tubing, shortening their service life, but also increases the frictional resistance during the oil extraction process. To solve this problem, a centralizer is needed. The main function of the sucker rod centralizer is to prevent direct contact between the sucker rod and the inner wall of the tubing, thereby effectively reducing the friction and wear between the two. By installing a centralizer on the sucker rod, during the oil extraction process, as the sucker rod moves up and down, the centralizer's centralizing blades contact the inner wall of the tubing and generate a supporting force, thus keeping the sucker rod in the center position of the tubing at all times. Existing ball-bearing centralizers primarily rely on the ball structure to reduce friction and torque, thereby mitigating the risk of breakage and jamming during downhole operations. The manufacturing process for ball-bearing centralizers involves first creating the centralizer's cylindrical structure through casting, followed by milling to remove excess material and ensure the centralizer parts meet the required dimensional accuracy and surface finish standards. However, in the ball installation stage, traditional methods typically employ a hammering method. This involves aligning the balls with the spiral mounting grooves on the centralizer and then hammering them into the grooves to complete the overall assembly. However, hammering makes it difficult to control the force, easily causing mechanical damage to the balls and disrupting their shape. Once the ball shape is damaged, its rolling performance significantly decreases, leading to a poorer guiding effect of the centralizer and consequently affecting the overall operating efficiency and lifespan of the pumping system.

[0003] To address the aforementioned issues, this application proposes a petroleum development apparatus for forming a centralizer. Summary of the Invention

[0004] This invention proposes a centralizer processing and forming device for oil extraction, which solves the problem in related technologies where the ball bearings on the centralizer are usually installed by striking, which can easily cause mechanical damage to the ball bearings due to improper force control, resulting in damage to the shape and a decrease in rolling performance, thereby affecting the guiding effect of the centralizer, the operating efficiency of the oil pumping system, and the life of the equipment.

[0014] As a further optimization of the present invention, an oil collection groove is provided on the processing table between the fixture and the cleaning component, and a filter screen is placed on the top of the oil collection groove. A drain pipe connected to the oil collection groove is connected to the front of the processing table.

[0015] The above-described technical solution of the present invention has the following beneficial technical effects: 1. An electric guide rail drives the ring body to move and cover the centralizer with a flexible cover. A first electric push rod drives the arc-shaped air pipe to move downward, allowing the cleaning and inspection component to be inserted into the spiral mounting groove of the centralizer. The electric guide rail continues to drive the ring body to move, and the clamp drives the centralizer to rotate. The two work together to move the cleaning and inspection component in the spiral mounting groove to clean impurities. During cleaning, the air nozzle on the arc-shaped air pipe blows hot air onto the centralizer, heating it to facilitate the installation of the ball bearings. At the same time, it blows up impurities, which are then extracted by the dust extraction component along the channel inside the flexible cover. After cleaning, the first electric push rod drives the arc-shaped air pipe to move the cleaning and inspection component upward, and the electric guide rail drives the ring body to retract the flexible cover, exposing the centralizer mounting groove. This cleaning and pretreatment method avoids the interference of impurities on the installation and operation of the ball bearings, reduces problems such as ball bearing jamming and wear, ensures smooth installation of the ball bearings and good operation of the centralizer, extends the service life of the equipment, and improves the operating efficiency of the oil pumping system. 2. When the cleaning and detection component moves within the spiral mounting groove of the centralizer to clean impurities, its internal components move upwards, pressing against the first pressure sensor inside the cleaning and detection component. This triggers the detection function of the first pressure sensor, allowing for timely detection of defects within the spiral mounting groove. This enables centralizers that do not meet installation requirements to be screened out in advance, avoiding problems such as insecure ball bearing installation and unstable operation caused by defects in the mounting groove, thereby improving production efficiency and product quality reliability. 3. After cleaning and inspecting the spiral mounting groove of the stabilizer, the balls are poured into the sorting assembly. The second motor drives the sorting disc inside the hollow cylinder to rotate, causing the balls to enter between adjacent tooth blocks and slide down the discharge pipe into the storage box. The second pressure sensor can detect the weight of the balls on the sorting disc. If the weight is not up to standard, it can be dealt with in time. When the balls fall down the discharge pipe, cold air is blown into them, which can both blow away dust and cool the balls. The blown-off dust is extracted by the dust extraction component. This process realizes the orderly screening of the balls, ensuring that the balls entering the installation stage are of qualified quality. At the same time, it completes cleaning and cooling, improves the installation quality of the balls and subsequent operating performance, and reduces equipment failures caused by problems with the balls themselves. 4. When the ball falls into the storage box, the magnetic lubrication assembly can be driven by a robotic arm to magnetically attract the ball in the storage box using two magnetic blocks on the assembly. After the ball is attracted, the elastic piston on the magnetic lubrication assembly will also be stressed. The third pressure sensor inside the fixed cylinder, which is in contact with the elastic piston, will detect the weight of the ball and compare it with the weight detected by the second pressure sensor. This dual detection method can more accurately determine the weight of the ball, ensuring that the weight of the ball entering the installation stage meets the requirements. This avoids problems such as unstable operation of the stabilizer and accelerated wear caused by ball weight deviation, thus improving the stability and reliability of the equipment operation. 5. The robotic arm moves the magnetically attracted ball bearings to the spiral mounting groove of the centralizer. The magnetic lubrication assembly moves downward, applying a downward force to the ball bearings. The elastic piston on the fixed cylinder is compressed, providing elastic pressing and preventing damage to the ball bearings and mounting groove due to excessive initial pressure. The centralizer mounting groove is heated to facilitate ball bearing insertion. During the pressurization process, the elastic piston moves within the oil reservoir, pushing lubricating oil through the oil guide pipe to the oil injection pipe, lubricating the contact points between the ball bearings and the mounting groove, and reducing friction. When the elastic piston moves to the second push rod position, the second push rod supports the elastic push rod, pushing the ball bearings to be forcibly pressed into the spiral mounting groove, achieving staged pressing. After installation, the elastic piston resets, supplying lubricating oil for the next installation. This staged pressing and lubrication design avoids damage to the ball bearings and mounting groove due to excessive pressure or friction, improving the success rate and quality of ball bearing installation, and ensuring the operational performance and service life of the centralizer. 6. The present invention can drive the second push rod to move within the oil storage cavity via the second electric push rod, adjust the distance between the second push rod and the elastic push member, and adjust the amount of lubricating oil injected according to the actual situation, so as to ensure that the lubrication effect between the ball and the mounting groove reaches the best state, further reduce the friction when the ball is stuck, improve the installation efficiency and quality, and at the same time avoid the waste of lubricating oil and reduce production costs.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0019] like Figures 1-12 As shown, the present invention proposes a petroleum exploration and forming device using a centralizer, comprising a processing table 1 and a robotic arm 2; The clamp 3 is mounted on the top of the processing table 1 to hold the stabilizer and drive it to rotate; Cleaning component 4 is installed on the processing table 1 and located on the side of the fixture 3. It is used to blow hot air on the stabilizer and clean the impurities in its mounting slot. Cleaning component 4 includes cleaning and inspection component 43, which is used to clean the impurities in the mounting slot and detect its defects. The sorting component 5 is installed on the processing table 1 and is used to sort the balls and detect their weight. The magnetic lubrication assembly 6 is installed on the drive end of the robot arm 2. It is used to magnetically attract the ball and press it into the mounting groove of the stabilizer by the robot arm 2. When pressed in, the magnetic lubrication assembly 6 injects lubricating oil onto the ball. Dust extraction component 7 is installed on the processing table 1 and connected to the cleaning component 4 and the sorting component 5 respectively. It is used to extract impurities on the centralizer cleaned by the cleaning component 4 and dust on the sorting balls when the sorting component 5 sorts them.

[0020] During processing, the straightener is first held by clamp 3, and the cleaning component 4 blows hot air onto the spiral mounting groove on the straightener, while the cleaning and inspection component 43 moves along the spiral mounting groove to simultaneously clean impurities and inspect for defects. During this process, the clamp 3 drives the straightener to rotate, and in coordination with its movement, the impurities in the spiral mounting groove can be promptly extracted by the dust extraction component 7. After the spiral mounting groove in the straightener is cleaned and inspected, the ball bearings can be sorted by the sorting component 5 and their weight can be inspected. The robot arm 2 drives the magnetic lubrication component 6 to magnetically attract the specified ball bearings and press them into the mounting groove, while simultaneously injecting lubricating oil. The above design realizes the automation of cleaning, inspection, sorting, installation and dust removal in the processing of the straightener, reduces manual intervention, avoids damage caused by traditional hammering of the ball bearings, and improves processing quality and efficiency.

[0021] like Figure 3 and Figure 4 As shown, in this embodiment, the cleaning component 4 further includes an air passage block 41, a ring 42, a hot air blower 44, and an electric guide rail 45. The air passage block 41 is installed on the processing table 1 and located on the side of the fixture 3. A through air passage is provided inside the air passage block 41. A flexible cover 411 is connected to the side of the air passage block 41 near the fixture 3. The ring 42 is connected to the end of the flexible cover 411. A first electric push rod 421 is installed on the ring 42. An arc-shaped air blowing pipe 422 connected to the first electric push rod 421 is provided on the inner side of the ring 42. The flexible cover 411, the ring 42, and the arc-shaped air blowing pipe 422 all have downward notches. One end is connected to a flexible hose 441, which is connected to a hot air blower 44 installed on the back of the processing table 1. The inner side of the ring body 42 is connected to a blower nozzle 423 for blowing hot air onto the stabilizer. The cleaning and detection component 43 is installed on the top of the inner side of the arc-shaped blower 422. The electric guide rail 45 is installed on the processing table 1 and located between the air passage block 41 and the clamp 3. The drive end of the electric guide rail 45 is equipped with a mounting bracket 451 fixed to the ring body 42. The air passage block 41 is equipped with an air passage duct 412 that communicates with the air passage opening, and the air passage duct 412 is connected to the dust extraction component 7. Multiple circumferentially arranged guide wheels 413 that assist the stabilizer in rotating are installed inside the air passage opening.

[0022] After the stabilizer is fixed to the clamp 3, one end of the stabilizer can be inserted into the air block 41, placing it between multiple guide wheels 413. The guide wheels 413 can assist the stabilizer's rotation. Then, the electric guide rail 45 drives the mounting bracket 451 to move the ring 42 and the flexible cover 411, so that the flexible cover 411 connected to the ring 42 covers the stabilizer. Subsequently, the first electric push rod 421 on the ring 42 drives the arc-shaped air pipe 422 to move down, so that the cleaning detection piece 43 is inserted into the spiral mounting groove of the stabilizer. The electric guide rail 45 continues to drive the ring 42 to move, and the clamp 3 drives the stabilizer to rotate. The two work together to move the cleaning detection piece 43 on the arc-shaped air pipe 422 within the spiral mounting groove of the stabilizer. The cleaning detection piece 43 can be used to clean the impurities in the spiral mounting groove. During the cleaning process, the hot air blower 44 delivers hot air through the hose 441. The air is delivered to the arc-shaped blowing pipe 422, where hot air is blown onto the spiral mounting groove inside the stabilizer through the blowing nozzle 423. Impurities are drawn away by the dust extraction component 7 through the flexible cover 411, the air passage port of the air passage block 41, and the air passage duct 412. After cleaning the impurities from the spiral mounting groove of the stabilizer, the arc-shaped blowing pipe 422 is driven by the first electric push rod 421 to move the cleaning and detection component 43 upward away from the mounting groove. Then, the ring body 42 is driven by the electric guide rail 45 to move the flexible cover 411 to close, exposing the spiral mounting groove of the stabilizer, which facilitates the subsequent installation of the ball bearings. The cleaning and pretreatment method designed above effectively avoids the interference of impurities on the installation of the ball bearings and subsequent operation, reduces problems such as ball bearing jamming and wear caused by impurities, provides a guarantee for the smooth installation of the ball bearings and the good operation of the stabilizer, extends the service life of the equipment, and improves the operating efficiency of the entire oil pumping system.

[0023] like Figure 4 and Figure 5 As shown, in this embodiment, the cleaning detection component 43 includes a loading cylinder 431. The loading cylinder 431 is installed on the top of the inner side of the arc-shaped blower pipe 422. A first pressure sensor 435 is installed on the top of the loading cylinder 431. A shaft 432 that extends into the bottom of the loading cylinder 431 and faces the first pressure sensor 435 is slidably connected to it. A brush head 433 is installed at the bottom end of the shaft 432. A first spring 434 is sleeved on the shaft 432, and the two ends of the first spring 434 are respectively connected to the loading cylinder 431 and the brush head 433.

[0024] The first electric push rod 421 drives the arc-shaped air pipe 422 to move downwards, so that the brush head 433 of the cleaning detection piece 43 is inserted into the spiral mounting groove of the stabilizer. Under the action of the electric guide rail 45, the ring body 42 can drive the cleaning detection piece 43 on the arc-shaped air pipe 422 to move in the spiral mounting groove. During the movement, the stabilizer is driven to rotate by the clamp 3. With the movement of the brush head 433 in the spiral mounting groove, the impurities in the spiral mounting groove can be cleaned by the brush head 433. During the cleaning of the spiral mounting groove, if the brush head 433 touches a protruding part, the shaft connected to the brush head 433 will... 432 will be compressed upwards under pressure, compressing the first spring 434. The shaft 432 presses against the first pressure sensor 435. After the first pressure sensor 435 is compressed, it detects the defects in the spiral mounting groove and promptly handles the straightener that does not meet the requirements for assembling the balls. After cleaning, the first electric push rod 421 can drive the arc-shaped blower 422 to move upwards away from the mounting groove. Then, the electric guide rail 45 drives the ring 42 to move the flexible cover 411 to retract, exposing the spiral mounting groove of the straightener, which is convenient for the subsequent installation of the balls. The above design simultaneously completes the cleaning of impurities and the detection of defects in the mounting groove, preventing defective parts from flowing into the next process.

[0025] In practical use, the first pressure sensor 435 is connected to the controller to receive the detected data in real time, helping staff to understand the situation promptly.

[0026] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in this embodiment, the sorting component 5 includes a hollow cylinder 51, which is installed on one side of the processing table 1. A feed hopper 511 communicating with the interior of the hollow cylinder 51 is installed on the hollow cylinder 51. An assembly port is provided on the outer side of the hollow cylinder 51, and a loading plate 512 is installed in the assembly port and a second pressure sensor 514 abuts against it. A second motor 513 is installed on the outer side of the loading plate 512. The output end of the second motor 513 is connected to a sorting plate 52 located inside the hollow cylinder 51. A sorting plate 52 is connected to... Multiple circumferentially arranged toothed blocks 521 are provided, with areas for placing ball bearings between adjacent toothed blocks 521. The bottom of the hollow cylinder 51 is connected to a discharge pipe 53 that passes through the other side of the processing table 1, and the end of the discharge pipe 53 is connected to a storage box 532. The outside of the storage box 532 is equipped with a dust extraction pipe 533 connected to the dust extraction component 7. A feed box 531 located below the hollow cylinder 51 is installed along the path of the discharge pipe 53. A cold air pipe 534 is connected to the feed box 531, and the cold air pipe 534 is connected to a cold air blower.

[0027] During ball bearing assembly, the balls enter the hollow cylinder 51 from the feed hopper 511. The second motor 513 drives the sorting disk 52 to rotate, separating and sorting the balls between the toothed blocks 521. The weight of the balls is transferred to the loading disk 512 through the sorting disk 52, triggering the second pressure sensor 514 to detect which adjacent toothed blocks 521 the balls do not meet the requirements. Then, the sorting disk 52 rotates the balls into the discharge pipe 53, allowing them to enter the storage box 532 along the discharge pipe 53. Qualified balls await subsequent installation, while unqualified balls are removed promptly. As the balls roll in the discharge pipe 53, a cold air fan blows cold air along the cold air pipe 534 to cool and remove dust from the balls in the feed box 531. The dust is then drawn away by the dust extraction component 7 through the dust outlet pipe 533. Finally, the balls fall into the storage box 532 for subsequent installation.

[0028] like Figure 2 As shown, in this embodiment, the dust extraction component 7 includes a dust extraction pump 71, which is installed on the back of the processing table 1. The dust extraction end of the dust extraction pump 71 is connected to a dust extraction pipe 72. The end of the dust extraction pipe 72 is connected to a first branch pipe 73 and a second branch pipe 74. The first branch pipe 73 is connected to the air duct 412, and the second branch pipe 74 is connected to the dust outlet pipe 533. After the dust extraction pump 71 is started, a negative pressure is generated through the dust extraction pipe 72. This negative pressure is transmitted to the air duct 412 via the first branch pipe 73. The airflow then acts on the air outlet of the air block 41, sucking in the impurities in the straightener mounting slot that are blown up by the hot air in the flexible cover 411 and ring 42 of the cleaning component 4. At the same time, the negative pressure is transmitted to the dust outlet pipe 533 through the second branch pipe 74, acting on the storage box 532 and the discharge pipe 53, and extracting the dust generated by the ball bearings in the sorting component 5 during the sorting and falling process. Finally, the impurities and dust are discharged through the dust pump 71, realizing the centralized treatment of pollutants during the cleaning and sorting process. In practical use, the dust pump 71 is connected to a dust collection bag or dust collection equipment, depending on the actual needs.

[0029] like Figure 1 , Figure 7 and Figure 8As shown, in this embodiment, the magnetic lubrication assembly 6 includes a fixed cylinder 61, an elastic piston 62, and a loading block 63. The fixed cylinder 61 is installed on the drive end of the robot 2. The fixed cylinder 61 is divided into an oil storage chamber and a loading chamber by a first partition 611. The first partition 611 is fixedly connected to the inner wall of the fixed cylinder 61. An oil supply pipe 612 arranged on the robot 2 and communicating with the oil storage chamber is connected to the fixed cylinder 61. The oil supply pipe 612 is connected to an oil supply pump. The elastic piston 62 is installed at the bottom of the fixed cylinder 61 and extends into the oil storage chamber. The loading block 63 is installed at the bottom of the elastic piston 62. Two magnetic blocks 631 are symmetrically connected at the bottom of the loading block 63. The inner sides of the two magnetic blocks 631 are formed with inclined surfaces to form a figure-eight structure. A through insertion channel is opened in the loading block 63. An oil injection pipe 64 is installed in the insertion channel. An oil guide pipe 641 communicating with the oil storage chamber is connected to the oil injection pipe 64. A control valve 642 is installed on the oil guide pipe 641.

[0030] When it is necessary to grasp the ball bearing, the robotic arm 2 drives the fixed cylinder 61 to move, so that the two V-shaped magnetic blocks 631 at the bottom of the loading block 63 approach the ball bearing in the storage box 532, and use magnetic force to attract the ball bearing. When installing the ball bearing, the robotic arm 2 drives the fixed cylinder 61 to move down, and the elastic piston 62 is compressed. The elastic force applies downward pressure to the ball bearing. At the same time, the lubricating oil in the oil storage chamber enters the oil injection pipe 64 through the oil guide pipe 641, and the lubricating oil is injected onto the ball bearing by the oil injection pipe 64. The control valve 642 controls the flow rate of the lubricating oil. The above design, through the elastic pressing action, can prevent hard damage to the position of the ball bearing and the spiral mounting groove of the stabilizer in the initial stage of ball bearing installation.

[0031] like Figure 8 As shown, in this embodiment, the elastic piston 62 includes a movable tube 621, a first piston 622, and a second spring 623. The movable tube 621 slides through the bottom of the fixed cylinder 61 and extends into the oil storage chamber. The top end of the movable tube 621 is connected to the first piston 622 located in the oil storage chamber. The loading block 63 is installed at the bottom end of the movable tube 621. The second spring 623 is sleeved on the movable tube 621, and both ends of the second spring 623 are respectively connected to the fixed cylinder 61 and the loading block 63. A first air hole is provided at the bottom of the fixed cylinder 61. A third pressure sensor 613 is installed at the bottom of the fixed cylinder 61, which abuts against the first piston 622. An active channel is opened in the active tube 621, and the active channel passes through the loading block 63. A circular opening is opened on the first piston 622, which communicates with the active channel. An elastic top member 65 extending into the circular opening is installed in the active tube 621. A second electric push rod 66 located in the loading cavity is installed on the first partition 611. The driving end of the second electric push rod 66 is connected to a second push rod 661 located in the oil storage cavity and facing the elastic top member 65.

[0032] When the magnetic block 631 magnetically attracts the ball, the ball exerts a downward force on the loading block 63, which applies a downward pulling force to the first piston 622 through the movable tube 621. Since the third pressure sensor 613 is in contact with the first piston 622, the weight of the ball can be detected to ensure that the weight of the ball entering the installation stage meets the requirements. When the ball bearings need to be pressed into the mounting slot of the stabilizer, as the downward pressure applied by the manipulator 2 increases, the loading block 63 pushes the movable tube 621 upward, compressing the second spring 623. The first piston 622 moves upward, squeezing the lubricating oil in the oil storage chamber. The lubricating oil enters the oil injection pipe 64 through the oil guide pipe 641 and is injected into the ball bearings through the oil injection pipe 64, allowing the lubricating oil to flow to the contact position between the ball bearings and the mounting slot, reducing the friction force of pressing the ball bearings. When the first piston 622 continues to move upward to the position corresponding to the second push rod 661, the elastic push member 65 inside the movable tube 621 can be pushed by the second push rod 661, and the elastic push member 65 inside the movable tube 621 can be pushed by the elastic push member 661. The top part 65 presses the ball into the mounting groove. Through the initial elastic pressing and subsequent hard pressing of the ball, a staged pressing method for the ball is achieved. Through the synergistic effect of this staged pressing and lubrication, damage to the ball and the mounting groove due to excessive pressure or friction during the insertion process is effectively avoided, thus improving the success rate and quality of ball installation. After installation, the elastic force of the second spring 623 drives the movable tube 621, the first piston 622 and the loading block 63 to reset, waiting for the next operation. Finally, the ball installation steps are repeated as described above to complete the overall assembly of the centralizer. It should be noted that during the installation of the ball bearings in the centralizer, when installing the first ball bearing, the cleaning component 4 can be used to blow hot air into the spiral mounting groove inside the centralizer to clean impurities and detect defects. When installing subsequent balls bearings, multiple balls can be spaced apart. The electric guide rail 45 drives the ring body 42 to move the arc-shaped air pipe 422 to the ball bearing installation position on the centralizer, and hot air is blown into the installation position to ensure that subsequent balls can be better inserted into the spiral mounting groove of the centralizer.

[0033] like Figure 8 and Figure 9 As shown, in this embodiment, the elastic top member 65 includes a second partition 651, which is fixed inside the movable tube 621. A first top rod 652 is slidably connected to the second partition 651. A second piston 653 located in the circular opening is installed at the top of the first top rod 652. The bottom end of the first top rod 652 slides through the loading block 63. A third spring 654 is sleeved on the first top rod 652, and the two ends of the third spring 654 are respectively connected to the second partition 651 and the second piston 653. A through second air hole is opened on the second partition 651.

[0034] As the first piston 622 continues to move upward in the oil reservoir, the second piston 653 located inside the circular opening of the first piston 622 can be supported by the second push rod 661. This causes the second piston 653 to drive the first push rod 652 to slide downward along the joint of the second partition 651. The bottom end of the first push rod 652 passes through the loading block 63 and pushes the ball, thus forcibly pressing the ball in. During this process, the third spring 654, which is sleeved on the first push rod 652, is compressed by the second piston 653. Its elasticity buffers the top pressure and prevents excessive pressure from damaging the ball. The second air hole on the second partition 651 is used to balance the air pressure in the movable tube 621, ensuring that the first push rod 652 and the second piston 653 can slide smoothly. After the top pressure is finished, the return elasticity of the third spring 654 pushes the second piston 653 and the first push rod 652 upward to return to the initial position, preparing for the next top push. It should be noted that in actual use, the second push rod 661 can be moved in the oil storage chamber by the second electric push rod 66, and the distance between the second push rod 661 and the second piston 653 can be adjusted, thereby controlling the amount of oil that the first piston 622 pushes to deliver lubricating oil to the oil injection pipe 64. In practical use, after the lubricating oil in the oil storage chamber has completed one ball lubrication cycle, the lubricating oil can be transported to the oil storage chamber through the oil supply pipe 612 by the oil supply pump to achieve timely replenishment of the lubricating oil in the oil storage chamber. The oil inlet end of the oil supply pump is connected to the storage tank for storing lubricating oil through a pipeline, which is not shown in the figure. This is existing technology and will not be explained in detail.

[0035] like Figure 1 and Figure 12 As shown, in this embodiment, the clamp 3 includes a fixing block 31, on which a three-jaw chuck 33 and a first motor 32 that drives the three-jaw chuck 33 to rotate are mounted. When it is necessary to clamp the stabilizer, the three-jaw chuck 33 fixes the stabilizer by the synchronous movement of its three jaws. During the cleaning component 4's cleaning and inspection of the stabilizer's spiral mounting groove, the first motor 32 starts and drives the three-jaw chuck 33 to rotate, thereby causing the clamped stabilizer to rotate synchronously, so that the cleaning and inspection component 43 of the cleaning component 4 can move along the stabilizer's spiral mounting groove to complete the cleaning and inspection.

[0036] like Figure 1 As shown, in this embodiment, the processing table 1 has an oil collection tank located between the clamp 3 and the cleaning component 4, and a filter screen 101 is placed on the top of the oil collection tank. Protrusions are installed on the inner walls of the oil collection tank for the placement and removal of the filter screen 101. A drain pipe 102 connected to the oil collection tank is connected to the front of the processing table 1. The lubricating oil dripping during the processing flows into the oil collection tank after being filtered by the filter screen 101 and is recovered through the drain pipe 102. The recovery of lubricating oil realizes resource reuse and reduces production costs.

[0037] The specific working principle of this invention is as follows: The stabilizer is fixed to the three-jaw chuck 33 of the clamp 3. The electric guide rail 45 drives the ring body 42 and the flexible cover 411 to move and cover the stabilizer. The first electric push rod 421 drives the arc-shaped blow pipe 422 to move down, so that the cleaning and detection piece 43 is inserted into the spiral mounting groove. Then the three-jaw chuck 33 drives the centralizer to rotate. The cleaning detection component 43 moves with the centralizer and the ring 42 to clean impurities. The hot air blower 44 blows hot air through the blower nozzle 423. The impurities are drawn away by the dust extraction component 7 through the air duct 412. If the shaft 432 presses against the first pressure sensor 435, the installation groove defect is detected. The balls enter the sorting component 5 through the feed hopper 511, the sorting disk 52 rotates and sorts them, the second pressure sensor 514 detects the weight, the balls go through the discharge pipe 53 to the storage box 532, the unqualified balls are removed in time, the cold air pipe 534 removes dust, and the dust is drawn away by the dust extraction component 7 through the dust outlet pipe 533. The robotic arm 2 drives the magnetic lubrication assembly 6, the magnetic block 631 attracts the ball, the third pressure sensor 613 performs secondary weighing, the robotic arm 2 moves the ball to the mounting slot, the elastic piston 62 is elastically pressed in, and at the same time the oil injection pipe 64 injects lubricating oil. Finally, the second push rod 661 pushes the elastic push piece 65 to complete the hard pressing. Repeat the above steps to complete the overall installation of the ball on the stabilizer.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
