Description

Technical Field

[0001] This invention relates to the field of bead filling technology, and in particular to an automated bead filling mechanism and its usage method. Background Technology

[0002] Rolling bearings are fundamental components in modern machinery manufacturing, and their performance and lifespan directly affect the operational accuracy and reliability of the machine tool. As a key component of rolling bearings, the cage (also known as the ball socket) is used to precisely isolate and guide the rolling elements (such as steel balls), and its quality is paramount. Many companies, especially small and medium-sized manufacturers, still rely heavily on manual labor or semi-automated equipment in the steel ball assembly stage of the ball socket. Manual assembly suffers from low efficiency, high labor intensity, poor product consistency, and is prone to scratching the cage or steel ball surface due to improper operation.

[0003] Currently, while some existing automated ball-filling equipment has improved efficiency to some extent, it still has the following problems: during the injection molding process, burrs are prone to appear on the edge of the ball socket of the nylon retainer in the bearing. Burrs will significantly increase the frictional resistance when the steel ball is pressed in, resulting in poor assembly and even requiring additional pressure. This may cause mechanical damage to the retainer or steel ball (such as retainer deformation and scratches on the surface of the steel ball), thus resulting in poor practicality of the ball-filling equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of poor practicality of existing bead filling equipment, and to propose an automated bead filling mechanism and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated bead filling mechanism, comprising a support frame, a conveying mechanism on the support frame, and a storage component, a polishing component, a processing component, a bead filling component, and a collection basket arranged sequentially along the conveying direction. A material retrieval component is located below the storage component. Limiting components are located below the polishing component, processing component, and bead filling component. The polishing component includes a first electric telescopic rod fixedly installed on the inner wall of the top of the support frame. A first fixing plate is fixedly connected to the telescopic end of the first electric telescopic rod. An internal toothed ring is rotatably connected to the bottom of the first fixing plate.

[0009] Preferably, the telescopic end of the first electric telescopic rod is fixedly connected to a first mounting housing via a fourth electric telescopic rod. The first fixing plate is located within the inner ring of the first mounting housing, and the two together constitute a protective structure. A first motor is fixedly mounted on the first fixing plate, and a first gear is fixedly connected to the output end of the first motor. The first gear meshes with an internal gear ring.

The output end of the third motor is fixedly connected to the feeding block, and the bottom of the second storage bin is provided with an arc-shaped slide.

[0011] Preferably, the bead loading assembly includes a third electric telescopic rod fixedly installed on the inner wall of the top of the support frame. The telescopic end of the third electric telescopic rod is fixedly installed with an mounting plate and a second fixing block located below it. The mounting plate is rotatably connected to a first rotating ring. A second fixing plate is fixedly installed at the bottom of the second fixing block.

One third fixing block is fixedly installed at the bottom of the fixing ring, and the other third fixing block and the two baffles are fixedly installed at the bottom of the second fixing plate. The two third fixing blocks are respectively connected to clamping plates on opposite sides via ball joints and second springs.

[0014] A method for using an automated bead-filling mechanism, comprising the above-described automated bead-filling mechanism, includes the following steps:

[0015] S1. Loading and Transfer: The injection-molded retainers are placed into the first storage bucket in sequence. The rubber ball is driven by the hydraulic push rod to fit into the ball socket of the retainer to remove it. After being clamped by the arc-shaped clamping block, it is transferred by the screw to the bottom of the first electric telescopic rod.

[0016] S2. Initial Grinding and Dust Removal: Through the support plate and the arc-shaped rubber block positioning retainer, the first electric telescopic rod drives the first mounting housing and grinding ring to move down. The first gear drives the internal gear ring to rotate the grinding ring, grinding the burrs on the edge of the ball socket. After grinding, the air blowing pipe blows air and the dust collection box sucks up dust to remove dust and debris.

[0017] S3. Secondary polishing and residual cleaning: The arc-shaped clamping block moves the retainer after the initial polishing to the bottom of the second electric telescopic rod. After repeating the positioning process, the second electric telescopic rod drives the second mounting housing and nylon brush to move down and insert into the ball socket. The nylon brush is driven by the cam to reciprocate, removing burrs and cleaning residual dust for the second time. The dust collection box vacuums at the same time.

[0018] S4. Steel ball loading and precise positioning: The retainer is moved to the bottom of the third electric telescopic rod and positioned. The loading block feeds the steel balls in the second storage bucket into the arc-shaped slide one by one. The first rotating ring receives the steel balls and releases them uniformly above the ball socket. The second rotating ring drives the pressing head to correct the position of the steel balls. The clamping plate initially clamps and positions the steel balls under the action of the second spring.

[0019] S5. Steel ball pressing and finished product storage: Rotate the second rotating ring to align the pressing head with the steel ball. The fifth electric telescopic rod drives the pressing head to move down and press the steel ball into the ball socket. The clamping plate continues to elastically clamp and protect the parts. After pressing is completed, the arc-shaped clamping block clamps the finished product holder and moves it to the top of the storage basket. After being released, the finished product falls into the storage basket.

[0020] Compared with existing technologies, the advantages of this invention are:

[0021] 1. The present invention combines the initial grinding with the secondary grinding with the nylon brush, which not only thoroughly removes the burrs on the edge of the ball socket hole, but also polishes and treats the inside of the hole through the reciprocating motion of the nylon brush, ensuring the smoothness of the ball socket hole surface.

[0022] 2. The present invention uses the air blowing pipe and the dust collection box to form a closed blowing and suction dust removal system, which completes the dust removal in a relatively closed space, avoids cross-contamination, significantly improves the cleanliness of the product, and reduces the risk of bearing failure due to impurities from the source.

[0023] 3. The present invention adopts a rubber ball interlocking material picking method and an internal support positioning method formed by an arc-shaped rubber block and a support plate. Both are flexible contacts, which effectively avoids scratches or deformation on the surface of the gripper during the gripping and fixing process, and ensures the integrity of the workpiece.

[0024] 4. This invention achieves batch and precise feeding of steel balls through the unified receiving and releasing of the first rotating ring. The position of the steel balls is corrected by the second rotating ring and the pressing head, and the steel balls are pre-clamped by the elastic clamping plate to ensure the centering of the steel balls before pressing. The pressing process driven by the fifth electric telescopic rod is stable and controllable. With the buffering effect of the elastic clamping, the steel balls are smoothly and accurately pressed in, eliminating jamming and damage, and achieving a high assembly success rate.

[0025] 5. This invention achieves full automation of the entire process from material feeding and two rounds of grinding and cleaning to final steel ball pressing. Through transfer components such as lead screws and arc-shaped clamping blocks, seamless connections are made between each workstation without manual intervention, which greatly improves production efficiency and reduces labor costs.

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Reference Figures 1 to 12An automated bead filling mechanism includes a support frame 1, on which a conveying mechanism is provided. The conveying mechanism consists of two sets of symmetrically distributed conveying components. Each conveying component includes a lead screw 8 rotatably connected to the support frame 1. The outer wall of the lead screw 8 is threaded with multiple clamping devices (this is prior art and will not be described in detail). The clamping end is equipped with an arc-shaped clamping block 9. The bottom of the clamping device is slidably connected to the support frame 1. Along the conveying direction of the conveying mechanism, the support frame 1 is sequentially provided with a storage component, a grinding component, a processing component, a bead filling component, and a collection basket 7. Hydraulic push rods 10 are provided below the storage component, grinding component, processing component, and bead filling component. The storage component includes a first collection bucket 2 fixed to the inner wall of the top of the support frame 1. Multiple retainers 24 are stacked inside the first collection bucket 2. An interception component is provided on the inner wall of the lower end of the first collection bucket 2. The interception component consists of multiple ring-shaped arrayed blocks 14. The blocks 14 are slidably connected to the inner wall of the first collection bucket 2 and elastically connected to the bucket body through a first spring 15. The top of block 14 is designed with a sloping structure. Below the storage component is a material retrieval component, which includes a storage block installed at the telescopic end of the corresponding hydraulic push rod 10. The outer wall of the storage block has multiple storage holes arranged in a ring array. Each storage hole is connected to a rubber ball 16 via a drive rod. When starting work, the storage block is first pushed into the first storage bucket 2 via the hydraulic push rod 10. Then, the drive rod inside the storage block is activated to squeeze the rubber ball 16 into the ball socket of the retainer 24. The elasticity of the rubber ball 16 is used to press the rubber ball 16 into the ball socket of the retainer 24. The deformation allows it to fit tightly into the ball socket, and then the hydraulic push rod 10 retracts, driving the retainer 24 down through the rubber ball 16. At this time, the stop block 14 is squeezed and compressed back into the inner wall of the first receiving bucket 2. After the retainer 24 has completely passed, the stop block 14 returns to its original position under the action of the first spring 15, continuing to support the remaining retainers 24 above. The rubber ball 16 achieves fitting with the ball socket of the retainer 24 through elastic deformation, which can avoid damage to parts caused by hard contact and ensure the stability and reliability of the material handling process.

[0041] Below the grinding assembly, processing assembly, and bead loading assembly, there are all limiting components. Each limiting component includes a support plate 19 and a limiting block, both fixedly installed on the telescopic ends of the corresponding hydraulic push rods 10. Multiple arc-shaped rubber blocks 26 are fixedly connected to the outer wall of the limiting block via telescopic rods. Multiple air-blowing pipes 25 arranged in a circular array are rotatably connected to the top of the limiting block located at the grinding assembly. Below the grinding assembly and processing assembly, there are dust-collecting components. Each dust-collecting component includes a dust collection box 11, which is fixedly connected to the support plate 19 on the corresponding side via a suction pipe 12. The suction pipe 12 is a flexible hose. The grinding assembly includes a first electric telescopic rod 3 fixedly installed on the inner wall of the top of the support frame 1. The telescopic end of the first electric telescopic rod 3 is fixedly connected to a first... A fixed plate 20 is fixedly connected to a first mounting housing 18 via a fourth electric telescopic rod 17. The first fixed plate 20 is located within the inner ring of the first mounting housing 18, and the two together form a protective structure. A first motor is fixedly mounted on the first fixed plate 20, and a first gear 21 is fixedly connected to the output end of the first motor. An internal gear ring 22 is rotatably connected to the bottom of the first fixed plate 20. The first gear 21 meshes with the internal gear ring 22 to form a transmission system. Two grinding rings 23 are fixedly mounted on the bottom of the internal gear ring 22, forming a grinding gap between the two grinding rings 23. The retainer 24 removed by the unloading assembly is held by an arc-shaped clamping block 9, and the lead screw 8 drives it to move to directly below the first electric telescopic rod 3. Subsequently, the hydraulic push rod 10 of this station extends. The support plate 19 is pushed against the bottom of the retainer 24, while the telescopic rod pushes the arc-shaped rubber block 26 to press tightly against the inner wall of the retainer 24, forming a double positioning to achieve three-dimensional constraint on the retainer 24, ensuring that it does not shift during the grinding process and guaranteeing processing accuracy. Then, the arc-shaped clamping block 9 is released, and the first electric telescopic rod 3 is activated, driving the first mounting housing 18 and the first fixing plate 20 to move down until the first mounting housing 18 contacts the support plate 19. At this time, the retainer 24 is completely enclosed in the protective space formed by the first mounting housing 18 and the first fixing plate 20, effectively isolating the dust generated during the grinding process. The two grinding rings 23 at the bottom of the internal toothed ring 22 are located on both sides of the retainer 24. After the first motor is started, The first gear 21 drives the internal gear ring 22 to rotate, driving the two grinding rings 23 to simultaneously grind the edge of the ball socket of the retainer 24 to remove burrs. After grinding, the first electric telescopic rod 3 is raised, and at the same time the fourth electric telescopic rod 17 extends, causing the grinding ring 23 to move upward and separate from the retainer 24, while the first mounting housing 18 remains in place. At this time, the grinding ring 23 is located above the retainer 24 and still forms a closed space with the first mounting housing 18. Subsequently, the air blowing pipe 25 rotates and blows out the dust and debris in the ball socket. At the same time, the dust collection box 11 at the corresponding position sucks out the blown-out dust through the suction pipe 12, effectively reducing residue. Finally, the first electric telescopic rod 3 continues to move upward, completely exposing the retainer 24 for subsequent processes.

[0042] The processing assembly includes a second electric telescopic rod 4 fixedly installed on the top of the inner wall of the support frame 1. A second mounting housing 27 is fixedly installed at its telescopic end. A first fixing block 29 is fixedly installed on the inner wall of the second mounting housing 27. Multiple nylon brushes 28 are slidably connected to the outer wall of the first fixing block 29. A second motor is fixedly installed inside the first fixing block 29. A cam 30 is fixedly connected to the output end of the second motor. Multiple nylon brushes 28 are arranged in a ring around the periphery of the cam 30. The retainer 24, after initial polishing, is held by an arc-shaped clamping block 9 and moved to the area below the second electric telescopic rod 4. The positioning process is repeated: the hydraulic push rod 10 pushes the support plate 19 to abut the retainer. At the bottom of the retainer 24, the arc-shaped rubber block 26 is tightly attached to the inner wall of the retainer 24 to form a stable constraint. Then, the second electric telescopic rod 4 extends and drives the second mounting housing 27 to move down until it closes with the support plate 19, forming a relatively closed processing space. At this time, the nylon brush 28 is inserted into the ball socket of the retainer 24. After the second motor is started, the cam 30 starts to rotate, pushing the nylon brush 28 to make reciprocating linear motion along the first fixed block 29 to remove the residual burrs inside the ball socket and to perform secondary polishing on the edge of the hole. At the same time, the reciprocating motion of the brush body carries out the dust and debris inside the hole. The fallen debris is finally sucked away by the dust collection box 11 of this station to ensure that the ball socket is clean.

[0043] The support frame 1 is equipped with a feeding assembly, which includes a second storage bin 5 fixedly installed on the inner wall of the top of the support frame 1, corresponding to the position of the bead loading assembly. A feeding block 31 is rotatably connected to the bottom of the inner wall of the second storage bin 5, and a third motor is fixedly installed on its outer wall. The output end of the third motor is fixedly connected to the feeding block 31. An arc-shaped slide rail 13 is provided at the bottom of the second storage bin 5. The bead loading assembly includes a third electric telescopic rod 6 fixedly installed on the inner wall of the top of the support frame 1. A mounting plate and a second fixing block 39 located below the telescopic end of the third electric telescopic rod 6 are fixedly installed. A first rotating ring 32 is rotatably connected to the mounting plate. A fourth motor is fixedly installed on the top of the mounting plate. A second gear 35 is fixedly connected to the output end of the fourth motor. The second gear 35 meshes with the gear teeth of the first rotating ring 32. The discharge port of the arc-shaped slide rail 13 corresponds to the position of the first rotating ring 32. A second fixing plate 36 is fixedly installed at the bottom of the second fixing block 39, and a fixing ring 33 is fixedly installed on the outer wall of the second fixing plate 36. The inner ring of the fixed ring 33 is provided with a second rotating ring 38, which is rotatably connected to the second fixed block 39. The inner wall of the second fixed block 39 is fixedly installed with a fifth motor, and the output end of the fifth motor is fixedly connected with a third gear 40. The third gear 40 meshes with the gear teeth of the second rotating ring 38. The outer wall of the second rotating ring 38 is fixedly installed with a ring array of multiple fifth electric telescopic rods 45. The telescopic end of each fifth electric telescopic rod 45 is fixedly installed with a pressing head 37. The top of the second fixed plate 36 is provided with multiple circular holes, and the bottom is provided with multiple sets of clamping components corresponding to the circular holes one by one. The clamping components include two symmetrically arranged third fixed blocks 44 and two symmetrically arranged baffles 41. One third fixed block 44 is fixedly installed at the bottom of the fixed ring 33, and the other third fixed block 44 and the two baffles 41 are fixedly installed at the bottom of the second fixed plate 36. The two third fixed blocks 44 are respectively connected to the clamping plate 34 through a ball joint 43 and a second spring 42 on opposite sides.

[0044] After secondary polishing, the retainer 24 is held by the arc-shaped clamping block 9 and moved to directly below the third electric telescopic rod 6. The positioning process is repeated: the support plate 19 abuts against the bottom of the retainer 24, the arc-shaped rubber block 26 presses against its inner wall, and then the third electric telescopic rod 6 is extended so that the two third fixing blocks 44 and the two baffles 41 of the clamping assembly are located around the corresponding ball socket holes. A circular through groove corresponding to the number of ball sockets in the retainer 24 is opened on the first rotating ring 32, and a retractable locking block is provided in the groove (this is prior art). (This will not be elaborated further). During steel ball assembly, the third motor is started to drive the feeding block 31 to rotate, feeding the steel balls in the second storage bin 5 one by one into the arc-shaped slide 13. At the same time, the fourth motor drives the second gear 35 to drive the first rotating ring 32 to rotate, causing the steel balls to fall into each through slot in sequence. The locking block restricts the steel balls within the first rotating ring 32. After all slots are filled with steel balls, the locking block retracts, and the steel balls fall through the round hole of the second fixing plate 36 under the action of gravity to the top of the ball socket. This centralized feeding method can effectively avoid misalignment. If any part is missing, the fifth motor is then started, driving the third gear 40 to rotate. This rotates the second rotating ring 38 by a certain angle, causing the pressing head 37 to push the steel ball on the second fixing plate 36 that has not yet fallen into the ball socket into the corresponding round hole. The baffle 41 limits the steel ball, and the two clamping plates 34 clamp the steel ball under the action of the second spring 42, achieving initial positioning and providing an accurate reference for subsequent pressing. The second rotating ring 38 is adjusted so that the pressing head 37 is directly above the steel ball, and its arc-shaped contour matches the top of the steel ball, forming surface contact. This helps to distribute pressure and improve assembly stability. Then, the fifth electric telescopic rod 45 is extended to push the pressing head 37 down and press the steel ball into the ball socket. During the pressing process, the clamping plate 34 continuously provides elastic clamping under the action of the second spring 42, which not only prevents the steel ball from shifting, but also absorbs the impact through deformation, protecting the steel ball and the surface of the retainer 24. Finally, the third electric telescopic rod 6 is retracted, and the arc-shaped clamping block 9 clamps and moves the assembled retainer 24 to the top of the storage basket 7. After release, it falls into the basket to complete the material collection.

[0045] A method for using an automated bead filling mechanism Apply the above Automated bead filling mechanism This includes the following steps:

[0046] S1. Loading and Transfer: The injection-molded retainer 24 is placed into the first storage bucket 2 in sequence. The rubber ball 16 is driven by the hydraulic push rod 10 to fit into the ball socket of the retainer 24 to remove it. After being clamped by the arc-shaped clamping block 9, it is transferred by the screw 8 to the bottom of the first electric telescopic rod 3.

[0047] S2. Initial grinding and dust removal: The first electric telescopic rod 3 drives the first mounting housing 18 and grinding ring 23 to move down through the support plate 19 and the arc-shaped rubber block 26 positioning retainer 24. The first gear 21 drives the internal gear ring 22 to rotate the grinding ring 23, grinding the burrs on the edge of the ball socket. After grinding, the air blowing pipe 25 blows air and the dust collection box 11 sucks up the dust to remove dust and debris.

[0048] S3. Secondary polishing and residual cleaning: The arc-shaped clamping block 9 moves the retainer 24 after the initial polishing to the bottom of the second electric telescopic rod 4. After repeating the positioning process, the second electric telescopic rod 4 drives the second mounting housing 27 and the nylon brush 28 to move down and insert into the ball socket. The cam 30 drives the nylon brush 28 to reciprocate, removing burrs and cleaning residual dust for the second time. The dust collection box 11 vacuums simultaneously.

[0049] S4. Steel ball loading and precise positioning: The retainer 24 is moved to the bottom of the third electric telescopic rod 6 and positioned. The loading block 31 feeds the steel balls in the second storage bucket 5 into the arc-shaped slide 13 one by one. The first rotating ring 32 receives the steel balls and releases them uniformly above the ball socket. The second rotating ring 38 drives the pressing head 37 to correct the position of the steel balls. The clamping plate 34 initially clamps and positions the steel balls under the action of the second spring 42.

[0050] S5. Steel ball pressing and finished product storage: Rotate the second rotating ring 38 to align the pressing head 37 with the steel ball. The fifth electric telescopic rod 45 drives the pressing head 37 to move down and press the steel ball into the ball socket. The clamping plate 34 continuously and elastically clamps and protects the parts. After pressing is completed, the arc-shaped clamping block 9 clamps the finished product holder 24 and moves it to the top of the storage basket 7. After being released, the finished product falls into the storage basket 7.

[0051] In operation, the molded retainer 24 is sequentially placed into the first storage container 2. When loading the ball begins, the hydraulic push rod 10 is first extended to insert the rubber ball 16 into the first storage container 2. Then, the drive rod is activated to press the rubber ball 16 into the ball socket of the retainer 24, so that the rubber ball 16 fits into the ball socket of the retainer 24. Then, the hydraulic push rod 10 is retracted, and the retainer 24 is moved downward by the rubber ball 16. The removed retainer 24 is then clamped by the arc-shaped clamping block 9. Then, the lead screw 8 drives the arc-shaped clamping block 9 to move, thereby moving the retainer 24 to directly below the first electric telescopic rod 3. The hydraulic push rod at this position is then extended. Push rod 10 causes support plate 19 to abut against the bottom of retainer 24. At this time, arc-shaped rubber block 26 on hydraulic push rod 10 will abut against the inside of retainer 24. Finally, release arc-shaped clamping block 9, and then start the first electric telescopic rod 3 to move the first mounting housing 18 and the first fixing plate 20 downward until the first mounting housing 18 abuts against support plate 19 and stops. At this time, retainer 24 is completely isolated inside the first mounting housing 18 and the first fixing plate 20. Retainer 24 is located between two grinding rings 23. The first gear 21 rotates and drives the internal gear ring 22 to start rotating, thereby driving the two grinding rings 23 to rotate and grind the edge part of the ball socket of retainer 24.

[0052] After polishing, the first electric telescopic rod 3 is lifted, and at the same time, the fourth electric telescopic rod 17 begins to extend, causing the polishing ring 23 to move upward a certain distance while the first mounting housing 18 remains stationary. Finally, the polishing ring 23 is located above the retainer 24, forming a closed space with the first mounting housing 18. Subsequently, the rotating air pipe 25 blows air into the ball socket of the retainer 24, causing the polished dust and debris to be blown away from the ball socket. The support plate 19 here is connected to the dust collection box 11 through the suction pipe 12. When the air pipe 25 blows air, the dust collection box 11 will also suck away the dust and debris blown out by the air pipe 25 through the suction pipe 12. Then, the first electric telescopic rod 3 is lifted to expose the retainer 24. After the initial polishing, the retainer 24 is clamped by the arc-shaped clamping block 9 and then moved below the second electric telescopic rod 4.

[0053] Repeat the previous steps until the support plate 19 is pressed against the bottom of the retainer 24 and the arc-shaped rubber block 26 is pressed against the inside of the retainer 24. Then extend the second electric telescopic rod 4 until the second mounting housing 27 stops pressing against the support plate 19. At this time, the support plate 19 and the second mounting housing 27 form a relatively closed space. The nylon brush 28 inside the second mounting housing 27 is inserted into the ball socket of the retainer 24. Then the cam 30 starts to rotate. During the rotation of the cam 30, the nylon brush 28, which is slidably connected to the first fixing block 29, will make a reciprocating linear motion under the pressure of the cam 30. While removing the burrs inside the ball socket of the retainer 24, it can also perform secondary polishing on the edge of the ball socket. The reciprocating linear motion of the nylon brush 28 can also carry away the residual dust and debris from the ball socket, so that it can be sucked away by the dust collection box 11 at that place.

[0054] After the retainer 24, which has been polished a second time, is moved directly below the third electric telescopic rod 6, the previous steps are repeated. The support plate 19 and the arc-shaped rubber block 26 are used to hold the bottom and inside of the retainer 24 in place. Then, the third electric telescopic rod 6 is extended until the clamping plates 34 of the inner and outer rings are located on both sides of the ball socket holes. The first rotating ring 32 has a circular through groove corresponding to the number of ball sockets in the retainer 24. When assembling the steel balls, the loading block 31 rotates and feeds the steel balls inside the second storage bucket 5 into the arc-shaped slide 13 one by one. At the same time, the second gear 35 rotates and drives the first rotating ring 32. 2. Rotation causes the steel balls sliding out of the arc-shaped slide 13 to fall sequentially into the through slots of the first rotating ring 32 until all the through slots on the first rotating ring 32 are filled with steel balls. Then, the retaining block retracts, and the steel balls fall above the ball socket. At this time, the third gear 40 can drive the second rotating ring 38 to rotate, thereby driving the pressing head 37 to rotate a certain extent, pushing the steel balls on the second fixing plate 36 that have not fallen into the ball socket into the round hole of the second fixing plate 36. The baffle 41 below the second fixing plate 36 limits the steel balls, and the clamping plates 34 of the inner and outer rings clamp the steel balls under the action of the second spring 42. Then, the second rotating ring 38 is rotated so that the pressing head 37 is directly above the steel balls. Then, the fifth electric telescopic rod 45 is extended to drive the pressing head 37 to move downward, pressing the steel balls into the ball socket of the retainer 24. Finally, the third electric telescopic rod 6 is lifted, and the arc-shaped clamping block 9 clamps the assembled retainer 24 and sends it into the storage basket 7.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
