Description

Technical Field

[0001] This invention relates to the field of machining equipment technology, and in particular to a fully automatic cage ball filling device and its filling method. Background Technology

[0002] In the field of modern high-end equipment manufacturing, bearing cages, as key basic transmission components, directly restrict the performance and reliability of major equipment due to their automated assembly precision and production efficiency. With the acceleration of industrial intelligence, the cage ball filling process is gradually transforming from traditional manual or semi-automated operations to fully automatic and high-precision processes. However, existing filling equipment often suffers from fragmented workstation layouts and inconsistent positioning benchmarks, resulting in multiple clamping operations for workpieces during transfer, which easily leads to cumulative tolerances. Simultaneously, mandrel lubrication relies heavily on manual brushing, resulting in uneven oil distribution and susceptibility to contamination. Furthermore, the lack of an effective synchronous recovery mechanism for metal debris and excess grease generated during filling not only leads to low equipment cleanliness but also increases the risk of filling jams or workpiece surface scratches, severely impacting the continuous operation capability and product consistency of the production line.

[0003] Chinese patent disclosure discloses a steel ball filling device (publication number: CN 116475732 A), comprising a first frame and a second frame. The first frame is equipped with a retainer conveying assembly, and the second frame is equipped with a steel ball guiding assembly and a filling assembly. The retainer conveying assembly includes a base plate with a positioning part. The steel ball guiding assembly includes a guide tube and a guide ball bottom ring, which is rotatable and includes a guiding surface and guide grooves spaced apart on the guiding surface. The outlet of the guide tube is aligned with the guiding surface. The filling assembly includes a limiting cylinder and a pressing outer sleeve. The limiting cylinder cooperates with the guide ball bottom ring to radially limit the steel ball. The limiting cylinder and the pressing outer sleeve are capable of vertical extension and retraction driven by a cylinder, and the lower end of the pressing outer sleeve faces... While the cage has pockets, this type of steel ball filling device uses a split frame design, relying on the vertical lifting of the press-fit outer sleeve to achieve filling. This results in a high center of gravity and insufficient rigidity, making it prone to high-frequency vibration. Furthermore, the workpiece lacks a through-type mandrel support during filling, relying solely on the bottom positioning part for restraint, causing the cage to easily deform during high-speed rotation filling. In addition, this type of structure lacks an online lubrication and waste oil synchronous recovery mechanism for the mandrel, and the pushing mechanism has a single function, unable to automatically reverse and clear obstacles when jammed. This severely restricts the long-term operational stability and production yield of the equipment. Therefore, a fully automatic cage steel ball filling device is needed. Summary of the Invention

[0004] The purpose of this invention is to address the significant systemic defects in the equipment structure and operation methods used in traditional cage steel ball filling operations: The workpiece transfer structure often employs a segmented, independent workstation design, lacking a unified mechanical reference transfer mechanism. This results in the workpiece undergoing multiple manual clamping or robotic repositioning processes during transfer, easily compromising final assembly accuracy due to accumulated tolerances. Simultaneously, mandrel lubrication relies heavily on manual, periodic application with a hand-held oil brush, failing to guarantee oil film uniformity. Furthermore, the equipment lacks a synchronous recovery mechanism, leading to disorderly accumulation of steel ball debris and excess grease on the worktable during filling, which can easily be carried back into the clamping area, causing scratches on the workpiece surface. Moreover, traditional pushing mechanisms typically only have unidirectional filling functionality, requiring manual intervention or additional rejection mechanisms when steel balls become stuck, increasing structural complexity and potential failure points. Finally, the feeding and docking structures often employ rigid, hard contact, lacking flexible buffering design, causing the cage to withstand significant impact at the moment of docking, easily resulting in hidden damage. Therefore, this invention proposes a fully automatic cage steel ball filling device.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a fully automatic steel ball filling device for a cage, comprising a cabinet body, characterized in that: a device frame is provided on the top of the cabinet body, a control box is provided on the inner wall of the top of the device frame, and a clamping station and a feeding station are arranged sequentially along the horizontal direction on the workbench of the device frame; the clamping station is provided with a material feeding component for workpiece posture correction, a steel ball pushing component for filling the workpiece with steel balls and retrieving residual steel balls, and a steel ball filling assembly, arranged sequentially along the material flow direction; the feeding station is provided with an automatic feeding component for pushing the workpiece to the clamping station; a micro-lubrication module is provided on one side above the automatic feeding component, and multiple universal casters with brakes are provided at the bottom of the cabinet body and are respectively arranged at the four corners of the bottom of the cabinet body. Production process integration: By integrating feeding, calibration, filling, and unloading functions within a single equipment frame, the fully closed-loop automation of cage ball filling is achieved, eliminating multiple manual interventions in traditional segmented operations and significantly improving production cycle time; High-efficiency workstation collaboration: The front-mounted layout of the micro-lubrication module allows the workpiece to undergo surface pretreatment before entering the core filling area, ensuring smooth mating between the mandrel and the workpiece and effectively reducing frictional losses during rotational filling; Flexible production line deployment: The design of braked swivel casters gives the heavy equipment extremely high mobility, enabling it to quickly respond to the adjustment needs of the workshop production line layout and adapt to flexible production modes of multiple varieties and small batches.

[0006] Preferably, the feeding assembly includes multiple base blocks, each base block having a steel ball feeding track block on its top. Steel ball clamping grooves are provided through both sides of the steel ball feeding track blocks. A steel ball filling mandrel is provided between the inner walls of the steel ball feeding track blocks. The steel ball filling mandrel is coaxially arranged with the steel ball clamping grooves. A steel ball chamber is installed on the top of the steel ball feeding track blocks. Steel ball flow channels are provided on both sides of the bottom of the inner wall of the steel ball chamber. A feeding block is located at the center inside the steel ball chamber. A feeding rod is located at the center of the top of the feeding block. A feeding motor baffle is connected to one end of the feeding rod. A reduction motor is installed on the top of the feeding motor baffle. A feeding motor support plate is connected to one side of the feeding motor baffle. The rotating feeding block forcibly disperses the steel balls, completely solving the problems of steel ball accumulation and bridging at the bottom of the bin, ensuring the continuity and orderliness of steel ball supply; the strict coaxiality of the steel ball filling mandrel and the steel ball clamping groove ensures that the movement trajectory of the steel balls before and after entering the cage is highly consistent, greatly reducing the risk of jamming during the filling process; the feeding motor forms a cantilever structure through a special baffle and support plate, which maintains the overall rigidity of the feeding unit while ensuring feeding power, preventing vibration deviation during long-term operation.

[0007] Preferably, a steel ball discharge chute is provided below the steel ball filling mandrel. The steel ball discharge chute is associated with the inner wall of the bottom block. A receiving box is provided on one side of the steel ball discharge chute. The discharge end of the receiving box has multiple discharge troughs. A detachable receiving and collection frame is provided below the discharge troughs. Through the independent discharge chute and receiving box, the debris or unqualified steel balls generated during the filling process are physically isolated from qualified finished products, avoiding secondary processing errors caused by cross-contamination. The detachable receiving and collection frame design means that the cleaning process does not require special tools or long downtime, significantly shortening the equipment maintenance window and ensuring the continuity of production. The closed or semi-closed recycling channel effectively curbs the splashing of metal debris, maintains the cleanliness of the equipment surroundings, and meets the 6S management requirements of modern factories.

[0008] Preferably, the steel ball pushing assembly includes a pin seat, one end of which is connected to a pin fixing block. Multiple steel ball pins are connected to one side of the pin fixing block and arranged in an equally spaced array. The steel ball pins can reciprocate along the direction approaching or moving away from the steel ball filling mandrel, and during the moving-away process, they form a sliding fit with the steel ball clamping groove. The steel ball pins are correspondingly arranged with the steel ball clamping groove, and the outer diameter of the steel ball pins matches the inner diameter of the steel ball clamping groove. A steel ball pushing cylinder is provided below the steel ball pin seat, and a steel ball feeding cylinder support plate is provided at the bottom of the steel ball pushing cylinder. By using the same set of steel ball ejectors to fill the steel balls during forward movement and to clean the residual steel balls in the slot during retraction using the mating gap, bidirectional functional reuse of a single drive source is achieved, simplifying the complexity of the mechanism. The equally spaced array of ejectors ensures that multiple rows of steel balls can be pushed into the cage simultaneously and in equal quantities, ensuring uniform force on the cage and preventing cage deformation caused by unilateral thrust. The adaptive design of the ejectors and the slot allows the mechanism to automatically force the discharge of faulty steel balls through a reset action when encountering slight jamming, improving the operational stability and fault tolerance of the equipment.

[0009] Preferably, the steel ball filling assembly includes a mandrel rotation assembly for a rotatable steel ball filling mandrel and an ejection assembly for ejecting the finished workpiece; the mandrel rotation assembly includes a mandrel support seat, a mandrel connecting rod is provided inside the mandrel support seat, one end of the mandrel connecting rod is connected to an ejection push plate, the ejection push plate cooperates with the steel ball filling mandrel, the other end of the mandrel connecting rod is connected to a motor mounting plate and a coupling is provided at the connection, the outer wall of the coupling is provided with a housing, and a rotary servo motor is connected to one side of the motor mounting plate; the ejection assembly includes an ejection guide rod, the other end of the ejection guide rod is connected to an ejection cylinder connecting plate, one end of the ejection cylinder connecting plate is connected to a main ejection cylinder, the mandrel connecting rod and the ejection guide rod are both connected to the mandrel support seat and one end of each is associated with the ejection push plate. The rotation of the mandrel, combined with the feeding action, allows the steel balls to fall precisely into the cage pockets during dynamic rotation, effectively avoiding ball jamming and misalignment during static filling. The ejector plate, constrained by the guide rod, pushes the material out axially, ensuring that the center of thrust coincides with the center of the workpiece, preventing scratches or deformation of the finished product during the ejection process. Rotational motion and axial linear motion are output in different dimensions through the same ejector plate, resulting in a compact structure and clear control logic, facilitating precision debugging and troubleshooting.

[0010] Preferably, the automatic feeding assembly includes a cage feeding base plate, a linear guide rail unit on the top of the cage feeding base plate, a feeding movable plate on the top of the linear guide rail unit, a feeding plate on one side of the top of the feeding movable plate, a plurality of guide rods passing through the feeding plate and correspondingly arranged thereon, a cage connecting rod above the guide rods, and a feeding push plate on one side of the guide rods and the cage connecting rods; a workpiece positioning mandrel is provided on the side of the feeding push plate facing the clamping station, and the workpiece positioning mandrel is connected to the clamping steel ball groove. The shaft is configured such that: the other end of the guide rod is connected to a guide rod push plate, one end of the guide rod push plate is connected to a main feeding cylinder, and a feeding cylinder mounting plate is provided between the main feeding cylinder and the feeding movable plate; a feeding cylinder bracket is provided on one side of the feeding movable plate, and one end of the feeding cylinder bracket is connected to a stroke cylinder for driving the feeding movable plate to move towards the clamping station; a limiting component is provided on one side of the stroke cylinder, and the limiting component includes a limiting block, on which a positioning guide rod and a hydraulic buffer rod are sequentially arranged from top to bottom. The workpiece positioning mandrel pre-positions the cage during the loading stage, and with the precise feeding of the stroke cylinder, it ensures that the workpiece can be fitted onto the loading mandrel with extremely high coaxiality, eliminating cumulative tolerances. The hydraulic buffer rod effectively absorbs the instantaneous impact of mechanical contact at the end of loading, preventing hidden damage to the brittle cage at the moment of docking. The parallel clamping mechanism formed by the guide rod and the cage connecting rod ensures the stability of the cage's posture during long-distance transportation, eliminating the risk of skewing or falling off.

[0011] Preferably, the micro-lubrication module includes an atomizing nozzle positioned above the workpiece positioning mandrel. An L-shaped bracket is connected to one side of the atomizing nozzle and fixed to the top of the loading plate via the L-shaped bracket. One end of the atomizing nozzle is connected to an oil supply pipe, and the other end of the oil supply pipe is sequentially connected to an electromagnetic control valve and a micro-oil-gas mixer via a pipeline. One end of the micro-oil-gas mixer is connected to an oil inlet pipe, and the other end of the oil inlet pipe is connected to an oil storage tank, which is located at the bottom of the cabinet body. The atomizing nozzle directly acts on the surface of the moving positioning mandrel, forming a micron-level uniform oil film. This achieves optimal friction reduction while minimizing oil volume, avoiding excessive oil contamination of the steel balls. The external oil storage tank, combined with the oil-gas mixer, enables quantitative supply and long-term storage of lubricant, reducing the frequency of manual replenishment and improving the automation level of the equipment. Positioning the oil storage tank at the bottom of the cabinet avoids the risk of lubricating oil leakage into the electrical control area, improving the electrical safety of the equipment operation.

[0012] Preferably, the top of the feed plate of the retainer is provided with a feed end oil collection groove located below the workpiece positioning mandrel. The feed end oil collection groove is inclined and its lower end is connected to a pull-out oil collection box. An oil collection cover is provided on the top of the feed end oil collection groove. The oil collection cover effectively captures oil dripping from the feed end, preventing oil stains from spreading to the linear guide or workpiece surface, ensuring the long-term cleanliness of the feed station. The pull-out oil collection box design makes waste oil cleaning as simple as pulling out a drawer, without the need for special tools or machine shutdown, which conforms to the ergonomic design concept. The centrally collected waste oil can be uniformly treated or recycled, which meets the requirements of green manufacturing and sustainable industrial production.

[0013] Preferably, the L-shaped bracket is provided with an adjustment hole for adjusting the position of the atomizing nozzle relative to the mandrel. The spray angle and distance of the nozzle can be flexibly changed through the adjustment hole, so that the same equipment can adapt to mandrels or cages of different diameters, enhancing the specification compatibility of the equipment; the mechanical adjustment structure is simple and reliable, and the nozzle alignment can be quickly completed without complex software parameter adjustments, shortening the equipment changeover and debugging time.

[0014] Preferred: Step 1: Automatic feeding and lubrication pretreatment After the equipment is started, the matching cage workpiece is sleeved on the workpiece positioning mandrel of the automatic feeding assembly. The micro-lubrication module is activated: the lubricating oil in the oil tank enters the micro-oil-air mixer through the oil inlet pipe, and forms atomized oil mist under the action of compressed air. The atomized nozzle, adjusted by the electromagnetic control valve and the waist-shaped adjustment hole on the L-shaped bracket, is precisely sprayed onto the surface of the workpiece positioning mandrel. Excess oil is captured by the oil collection tank at the feeding end and flows into the pull-out oil collection box along the inclined trough, completing the waste oil recovery. At the same time, the main feeding cylinder is activated, which drives the guide rod and the cage connecting rod through the guide rod push plate, causing the feeding push plate to move towards the clamping position. When the stroke cylinder drives the feeding movable plate to slide along the linear guide rail unit to the limit position, the limit block and hydraulic buffer rod in the limit component absorb the impact to ensure accurate positioning. Step Two: Workstation Connection and Posture Correction The feeding pusher continues to advance, driving the workpiece positioning mandrel and the cage to the clamping position. Here, the workpiece positioning mandrel and the steel ball filling mandrel are coaxially connected. The inner hole of the cage smoothly transitions between the two shafts and is sleeved onto the steel ball filling mandrel. After the handover is completed, the feeding pusher retracts, the workpiece positioning mandrel returns to its original position with the feeding end, and the cage remains on the steel ball filling mandrel, ready for the filling operation. At this time, the feeding assembly starts to work: the geared motor starts, and the feeding motor baffle and feeding motor support plate maintain stable output, drive the feeding rod to rotate, and then drive the feeding block inside the steel ball chamber to rotate; the feeding block disperses the steel balls in the steel ball chamber, so that they fall into the clamping steel ball grooves on both sides of the steel ball feeding ball channel block through the steel ball flow channel, and are stably supported by the bottom block, and the steel balls are neatly arranged around the steel ball filling mandrel; Step 3: Steel ball loading and bidirectional transfer The steel ball pushing assembly performs the filling action: the steel ball pushing cylinder provides reaction force through the steel ball feeding cylinder support plate, driving the ejector pin seat and ejector pin fixing block forward, and driving the arrayed steel ball ejector pins to insert into the steel ball clamping groove; during the filling stroke, the steel ball ejector pins forcefully push the steel ball into the retainer pocket; Subsequently, the spindle rotation assembly intervenes: the rotary servo motor drives the spindle connecting rod to rotate via the motor mounting plate and coupling, which in turn drives the steel ball filling spindle and cage to rotate at a specific angle, aligning the next empty pocket with the filling position; when steel ball recycling is performed, the steel ball ejector pin, during its retraction stroke, uses its outer diameter to slide against the steel ball clamping groove to push out any residual or stuck steel balls, achieving self-cleaning; the steel balls generated during the recycling process fall into the steel ball leakage chute, slide into the receiving box, and finally fall into the detachable receiving and collecting frame through multiple discharge troughs, achieving recycling and reuse; Step 4: Finished Product Return After all pockets of the retainer are filled, the steel ball pushing assembly is reset and the ejection assembly is activated: the main ejection cylinder drives the ejection guide rod through the ejection cylinder connecting plate, which drives the ejection pusher plate to move smoothly along the axial direction; the ejection pusher plate pushes the finished workpiece off the steel ball filling mandrel, causing it to detach from the mandrel support and enter the steel ball leakage slide. Step 5: Cyclic Reset and Overall Machine Support After a work cycle is completed, each cylinder and motor resets according to the preset sequence, waiting for the next cage to enter; the braked swivel casters at the bottom of the cabinet body are locked when the equipment is running to ensure the stability of the whole machine under high dynamic operation. When it is necessary to adjust the production line layout, the brakes can be released to move it flexibly.

[0015] The advantages of this invention are: This invention provides a fully automatic cage ball filling device. Through the intensive design of the workstation layout and the deep reuse of mechanism functions, it achieves a closed-loop fully automatic operation from workpiece loading, posture correction, ball filling to finished product unloading. Compared with existing technologies, it has significant functional advantages: First, by setting a workpiece positioning mandrel at the loading end and a ball filling mandrel at the clamping station, combined with the linear pushing of the automatic loading component, the coaxial relay and reference transfer of the workpiece between the two axes are realized, fundamentally eliminating the positioning error caused by multiple clamping and ensuring the posture stability of the cage during high-speed filling; Second, by utilizing the coordinated arrangement of a micro-lubrication module and an oil collection and recovery system, the mandrel is atomized and lubricated at the loading end, and a double-layer oil interception is formed by an oil collection hood and a pull-out oil collection box at the loading and filling stations, which not only significantly reduces the filling friction but also... The wear of the mandrel further maintains the cleanliness of the equipment's operating environment, eliminating potential quality hazards caused by oil contamination of the workpiece surface. Secondly, the steel ball pushing assembly uses a single cylinder to drive the steel ball ejector pin for reciprocating movement. By cleverly utilizing the fit between the ejector pin's outer diameter and the steel ball clamping groove, it completes the bidirectional function of pushing in and filling steel balls and retracting residual steel balls within the same stroke, greatly simplifying the drive structure and improving self-handling capabilities. Finally, the three-dimensional cooperation of the feeding assembly, mandrel rotation assembly, and ejection assembly ensures that the steel balls are precisely filled into the cage pockets during dynamic rotation. Combined with the bottom leakage slide and receiving collection frame, it achieves physical isolation and automatic classification of qualified products and waste materials (debris, residual balls). This significantly improves equipment uptime and maintenance convenience while ensuring filling accuracy, truly achieving the intelligent manufacturing requirement of "one-time clamping, fully controlled."

[0030] In this embodiment, a steel ball discharge chute is provided below the steel ball filling mandrel 46. The steel ball discharge chute is associated with the inner wall of the bottom block 47. A receiving box 14 is provided on one side of the steel ball discharge chute. The discharge end of the receiving box 14 is provided with multiple discharge troughs. A detachable receiving and collecting frame 15 is provided below the discharge troughs.

[0031] In this embodiment, the steel ball pushing assembly includes a pin seat, one end of which is connected to a pin fixing block 29. A plurality of steel ball pins 28 are connected to one side of the pin fixing block 29 and are arranged in an equally spaced array.

A rotary servo motor 10 is connected to one side of the motor mounting plate 9. The ejection assembly includes an ejection guide rod 12, with an ejection cylinder connecting plate at the other end. One end of the ejection cylinder connecting plate is connected to a main ejection cylinder 11. Both the mandrel connecting rod 8 and the ejection guide rod 12 are connected to the mandrel support 13, and one end of each is associated with the ejection push plate.

[0033] In this embodiment, the automatic feeding assembly includes a cage feeding base plate 19. A linear guide rail unit 18 is provided on the top of the cage feeding base plate 19. A feeding movable plate 20 is provided on the top of the linear guide rail unit 18. A feeding plate 23 is provided on one side of the top of the feeding movable plate 20. Multiple guide rods are provided through the feeding plate 23 and are correspondingly arranged. A cage connecting rod 24 is provided above the guide rods. A feeding push plate 25 is provided on one side of both the guide rods and the cage connecting rod 24. A workpiece positioning mandrel 39 is provided on the side of the feeding push plate 25 facing the clamping station. The workpiece positioning mandrel 39 is located in the same groove as the clamping steel ball groove. The shaft is configured such that: the other end of the guide rod is connected to a guide rod push plate 22, one end of the guide rod push plate 22 is connected to a main feeding cylinder 21, and a feeding cylinder mounting plate is provided between the main feeding cylinder 21 and the feeding movable plate 20; a feeding cylinder bracket 41 is provided on one side of the feeding movable plate 20, and one end of the feeding cylinder bracket 41 is connected to a stroke cylinder 40 for driving the feeding movable plate 20 to move closer to the clamping station; a limiting component is provided on one side of the stroke cylinder 40, and the limiting component includes a limiting block 44, on which a positioning guide rod 43 and a hydraulic buffer rod 42 are sequentially arranged from top to bottom. The workpiece positioning mandrel 39 pre-positions the cage during the feeding stage, and with the precise feeding of the stroke cylinder 40, it ensures that the workpiece can be fitted onto the filling mandrel with extremely high coaxiality, eliminating cumulative tolerances. The hydraulic buffer rod 42 effectively absorbs the instantaneous impact of mechanical contact at the end of feeding, preventing hidden damage to the brittle cage at the moment of docking. The parallel clamping mechanism formed by the guide rod and the cage connecting rod 24 ensures the stability of the cage's posture during long-distance transportation, eliminating the risk of skewing or falling off.

[0034] In this embodiment, the micro-lubrication module includes an atomizing nozzle 38 positioned above the workpiece positioning mandrel 39. An L-shaped bracket 36 is connected to one side of the atomizing nozzle 38 and fixed to the top of the loading plate 23 via the L-shaped bracket 36. One end of the atomizing nozzle 38 is connected to an oil supply pipe 35, and one end of the oil supply pipe 35 is connected in sequence to an electromagnetic control valve 34 and a micro-oil-gas mixer 33 via a pipeline. One bottom end of the micro-oil-gas mixer 33 is connected to an oil inlet pipe 17, and one end of the oil inlet pipe 17 is connected to an oil storage tank 16, which is located at the bottom of the cabinet body 2. The atomizing nozzle 38 acts directly on the surface of the moving positioning mandrel, forming a micron-level uniform oil film. This achieves the best friction reduction effect while minimizing the amount of oil, and avoids excessive oil contamination of the steel balls. The external oil tank 16, in conjunction with the oil-air mixer, enables quantitative supply and long-term storage of lubricant, reducing the frequency of manual replenishment and improving the automation level of the equipment. By placing the oil tank 16 at the bottom of the cabinet, the risk of lubricant leakage into the electrical control area is avoided, thus improving the electrical safety of the equipment operation.

[0035] In this embodiment, the top of the feed base plate 19 of the retainer is provided with a feed end oil collection groove 50 located below the workpiece positioning mandrel 39. The feed end oil collection groove 50 is arranged at an angle and its lower end is connected to a pull-out oil collection box 52. The top of the feed end oil collection groove 50 is provided with an oil collection cover 51. The oil collection cover 51 effectively captures oil stains dripping from the feed end, preventing oil stains from spreading to the linear guide rail or workpiece surface, and ensuring the long-term cleanliness of the feed station. The pull-out oil collection box 52 design makes waste oil cleaning as simple as pulling out a drawer, without the need for special tools or machine shutdown, which conforms to the ergonomic design concept. The centrally collected waste oil can be uniformly treated or recycled, which meets the requirements of green manufacturing and sustainable industrial production.

[0036] In this embodiment, the L-shaped bracket 36 is provided with an adjustment hole 37 for adjusting the position of the atomizing nozzle 38 relative to the mandrel. The spray angle and distance of the nozzle can be flexibly changed through the adjustment hole 37, so that the same equipment can adapt to mandrels or cages of different diameters, enhancing the specification compatibility of the equipment; the mechanical adjustment structure is simple and reliable, and the nozzle alignment can be quickly completed without complex software parameter adjustments, shortening the equipment changeover and debugging time.

[0037] In this embodiment: Step 1: Automatic feeding and lubrication pretreatment After the equipment is started, the matching cage workpiece is sleeved on the workpiece positioning mandrel 39 of the automatic feeding assembly. The micro-lubrication module is activated: the lubricating oil in the oil tank 16 enters the micro-oil-gas mixer 33 through the oil inlet pipe 17, and forms atomized oil mist under the action of compressed air. The atomized nozzle 38, adjusted by the electromagnetic control valve 34 and the waist-shaped adjustment hole 37 on the L-shaped bracket 36, is precisely sprayed onto the surface of the workpiece positioning mandrel 39. Excess oil is captured by the oil collection tank 50 at the feeding end and flows into the pull-out oil collection box 52 along the inclined trough, completing the waste oil recovery. At the same time, the main feeding cylinder 21 is activated, which drives the guide rod and the retainer connecting rod 24 through the guide rod push plate 22, and drives the feeding push plate 25 to move towards the clamping position. When the stroke cylinder 40 drives the feeding movable plate 20 to slide along the linear guide rail unit 18 to the limit position, the limit block 44 and the hydraulic buffer rod 42 in the limit assembly absorb the impact to ensure accurate positioning. Step Two: Workstation Connection and Posture Correction The feeding pusher plate 25 continues to advance, driving the workpiece positioning mandrel 39 and the cage to the clamping position. Here, the workpiece positioning mandrel 39 is coaxially connected with the steel ball filling mandrel 46. The inner hole of the cage completes a smooth transition between the two shafts and is sleeved onto the steel ball filling mandrel 46. After the handover is completed, the feeding pusher plate 25 retracts, the workpiece positioning mandrel 39 is reset with the feeding end, and the cage remains on the steel ball filling mandrel 46, ready for the filling operation. At this time, the feeding assembly starts to work: the reduction motor 5 starts, and the feeding motor baffle 6 and feeding motor support plate 45 maintain stable output, drive the feeding rod 7 to rotate, and then drive the feeding block 26 inside the steel ball chamber 49 to rotate; the feeding block 26 disperses the steel balls in the steel ball chamber 49, so that they fall into the clamping steel ball grooves on both sides of the steel ball feeding ball channel block 48 through the steel ball flow channel 27, and are stably supported by the bottom block 47. The steel balls are neatly arranged around the steel ball filling mandrel 46. Step 3: Steel ball loading and bidirectional transfer The steel ball pushing assembly performs the filling action: the steel ball pushing cylinder 31 provides a reaction force through the steel ball feeding cylinder support plate 32, driving the ejector pin seat and ejector pin fixing block 29 forward, and driving the arrayed steel ball ejector pins 28 to insert into the steel ball clamping groove; during the filling stroke, the steel ball ejector pins 28 forcefully push the steel ball into the retainer pocket. Subsequently, the spindle rotation assembly intervenes: the rotary servo motor 10 drives the spindle connecting rod 8 to rotate through the motor mounting plate 9 and the coupling, thereby causing the steel ball filling spindle 46 and the cage to rotate at a specific angle, so that the next empty pocket is aligned with the filling position; when the steel ball is recycled, the steel ball ejector pin 28, during its retraction stroke, uses its outer diameter to slide against the steel ball clamping groove to push out the residual or stuck steel balls in the opposite direction, achieving self-cleaning; the steel balls generated during the recycling process fall into the steel ball leakage chute, slide into the receiving box 14, and finally fall into the detachable receiving and collecting frame 15 through multiple discharge troughs, achieving recycling and reuse; Step 4: Returning finished products After all pockets of the retainer are filled, the steel ball pushing assembly is reset and the ejection assembly is started: the main ejection cylinder 11 drives the ejection guide rod 12 through the ejection cylinder connecting plate, which drives the ejection pusher plate to move smoothly along the axial direction; the ejection pusher plate pushes the finished workpiece out of the steel ball filling mandrel 46, so that it is separated from the mandrel support seat 13 and enters the steel ball leakage slide. Step 5: Cyclic Reset and Overall Machine Support After a work cycle is completed, each cylinder and motor resets according to the preset timing sequence, waiting for the next cage to enter; the braked universal casters 1 at the bottom of the cabinet body 2 are locked when the equipment is running to ensure the stability of the whole machine under high dynamic operation. When it is necessary to adjust the production line layout, the brake can be released to move flexibly.
