Description

Technical Field

[0001] This invention relates to the field of bearing processing application technology, specifically to a device for detecting the flange deformation of the outer box used in the production of thrust ball bearing cages. Background Technology

[0002] Thrust ball bearings are widely used in various mechanical equipment due to their high load-carrying capacity. The manufacturing quality of their cages directly affects bearing performance and lifespan. During production, the cage typically consists of an outer casing that encloses the inner casing to secure the steel balls. The outer casing's flange is prone to deformation, which can reduce bearing performance. Therefore, quality inspection of the cage's outer casing flange is crucial and requires specialized outer casing flange deformation detection equipment to ensure product quality.

[0003] However, existing cage manufacturing outer box flange deformation detection equipment has significant drawbacks in its operation. It requires substantial manual labor for loading, inspection, and unloading. Manual operation is not only inefficient but also prone to human error, leading to inaccurate results. Furthermore, existing equipment only inspects from one angle, failing to comprehensively assess the deformation of the cage outer box flange. This may result in missed defects, affecting product quality. The structural layout of existing equipment may also be loose, with unreasonable spacing between components, resulting in a large footprint and hindering installation and layout within limited production workshops. Additionally, the lack of proper coordination between components may cause delays or interference during material transfer and operation. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a device for detecting the flange deformation of the outer box used in the production of thrust ball bearing cages.

[0005] The technical solution adopted by this invention to solve its technical problem is: a device for detecting the flange deformation of the outer box in the production of thrust ball bearing cages, comprising a base, a feeding assembly, a transfer assembly, and a discharging assembly. The base serves as the basic support structure of the entire device. The feeding assembly and the discharging assembly are respectively fixed at both ends of the top of the base, ensuring clear and non-interfering input and output paths for materials. The feeding assembly is responsible for conveying the bearing cages to be inspected into the device, while the discharging assembly is used to convey the inspected bearing cages to subsequent processes or collection areas. A fixed seat and a rotatable turntable are installed on the top of the base between the feeding assembly and the discharging assembly. The fixed seat is used to stably place the bearing cages, providing a stable inspection platform for the first visual inspection assembly. The turntable can rotate, allowing the bearing cages to be displayed from all angles during the inspection process, facilitating inspection from different angles by the second visual inspection assembly, ensuring the comprehensiveness and accuracy of the inspection. The transfer assembly is installed on one side of the top of the base, responsible for transferring the bearing cages conveyed by the feeding assembly to the fixed seat, transferring the bearing cages on the fixed seat to the rotating disk, and finally transferring the inspected bearing cages on the rotating disk to the unloading assembly. A vision inspection assembly one is installed on the side of the top of the base away from the transfer assembly, corresponding to the fixed seat; a vision inspection assembly two is installed on the side of the top of the base away from the transfer assembly, corresponding to the rotating disk. Vision inspection assembly one is mainly responsible for inspecting the top of the bearing cage on the fixed seat, while vision inspection assembly two inspects the sides of the bearing cage on the rotating disk. This dual vision inspection assembly setup, inspecting the bearing cage from different angles, can more comprehensively detect deformation of the outer box's flange.

[0006] The transfer assembly includes left and right sliding plates, front and rear sliding plates, and a vertical plate. The left and right sliding plates move left and right and are fitted onto the top of the base. The front and rear sliding plates move and are fitted onto the top of the left and right sliding plates. The vertical plate is vertically fixed to the top of the front and rear sliding plates. A lifting plate is mounted on the side of the vertical plate closest to the fixed seat and the rotating disk. Electric grippers one and two are horizontally mounted on the side of the lifting plate away from the vertical plate. The engagement of the left and right sliding plates with the top of the base allows the entire transfer assembly to move left and right on the base. This movement provides sufficient space for the transfer assembly to accurately reach different positions such as the feeding assembly, the fixed seat, and the rotating disk, providing a basis for the transfer of the bearing cage. The front and rear sliding plates are mounted on top of the left and right sliding plates and can move back and forth on them. The distance between the first and second electric grippers is the same as the distance between the fixed base and the rotating disk, ensuring that the first and second electric grippers can operate simultaneously during the transfer process. When the first electric gripper transfers the bearing cage on the fixed base to the rotating disk, the second electric gripper can simultaneously transfer the bearing cage on the rotating disk to the unloading assembly, realizing the synchronous operation of gripping and transfer, which greatly improves the operating efficiency of the equipment.

[0007] Preferably, the feeding assembly includes a feeding conveyor frame and support legs. One end of the feeding conveyor frame is fixed to the top of the base, and the support legs are vertically supported at the bottom end of the feeding conveyor frame away from the base. A feeding plate chain is connected to the feeding conveyor frame via gear transmission. A feeding drive motor for driving the feeding plate chain is installed at the bottom end of the feeding conveyor frame. Feeding baffles are fixed on both sides of the top end of the feeding conveyor frame away from the base. The distance between the two feeding baffles is adapted to the diameter of the bearing cage being conveyed. By setting the feeding baffles, the position of the bearing cage can be effectively constrained, preventing it from deviating from the track due to vibration or other external forces during the conveying process, thereby avoiding the bearing cage from falling off.

[0008] Preferably, a retaining frame is installed at the top of the feeding conveyor frame near the base. The retaining frame has an inverted "U" shape, with a retaining drive cylinder vertically fixed in the middle. The bottom of the retaining drive cylinder is connected to a retaining plate via a push rod. In actual production, the transfer assembly needs a certain amount of time to complete the clamping and transfer operation of the bearing cage. Temporarily retaining the bearing cage on the conveyor belt using the retaining frame provides sufficient time for the operation of the transfer assembly.

[0009] Preferably, the transfer assembly further includes left and right translation drive cylinders for moving the left and right moving plates, front and back translation drive cylinders for moving the front and back moving plates, and lifting drive cylinders for raising and lowering the lifting plate. The left and right translation drive cylinders are horizontally mounted on the top of the base, with one end connected to the left and right moving plates via a push rod. The front and back translation drive cylinders are horizontally mounted on top of the left and right moving plates, with one end connected to the front and back moving plates via a push rod. The lifting drive cylinder is vertically mounted on one side of the upright plate near the top, with its bottom connected to the lifting plate via a push rod. This multi-dimensional movement coordination system provides the transfer assembly with extremely high flexibility and precision. Through the coordinated work of the left and right translation drive cylinders, front and back translation drive cylinders, and lifting drive cylinders, the transfer assembly can perform precise positioning and movement in three-dimensional space. A first slide rail is horizontally fixed to one side of the top of the base. A first slider, which slides along the first slide rail, is fixed to the bottom of the left and right sliding plates. A second slide rail is horizontally fixed to the top of the left and right sliding plates. A second slider, which slides along the second slide rail, is fixed to the bottom of the front and rear sliding plates. A third slide rail is vertically fixed to the side of the upright plate near the lifting plate. A third slider, which slides along the third slide rail, is fixed to the side of the lifting plate near the upright plate. The design of the slide rails and sliders also serves to dampen vibrations and guide movement. During movement, the slide rails and sliders effectively reduce direct friction between mechanical parts, reduce wear, and extend the service life of the equipment. Simultaneously, the guiding function of the slide rails and sliders ensures the accuracy of the movement direction, avoiding inaccurate positioning problems caused by mechanical errors.

[0010] Preferably, a base is fixed to the top of the platform, and a mounting bracket is fixed to the top of the base. The presence of the base provides a certain height for the mounting bracket, making the overall layout of the inspection equipment more reasonable and facilitating the operation of the transfer component and the vision inspection component with the mounting bracket. The mounting bracket has a cylindrical structure, and its internal diameter is adapted to the diameter of the bearing cage being inspected, allowing it to perfectly accommodate the bearing cage to be inspected. The mounting bracket has two slots for easy loading and unloading, greatly facilitating the removal and loading of the bearing cage.

[0011] Preferably, a mounting base is embedded in the top of the base, the rotating disk is rotated and fitted on the top of the mounting base, and a rotary drive motor for driving the rotating disk is installed at the bottom of the mounting base. The rotating and fitted design of the rotating disk allows the bearing cage to be rotated and displayed in all directions during the testing process.

[0012] Preferably, visual inspection component one includes a fixed plate, a movable block, and a machine vision camera. A sliding rod and a lead screw are fixed to one side of the fixed plate. The movable block is sleeved on the sliding rod and threadedly engaged with the lead screw. A rotating handle connected to the lead screw is installed at the end of the fixed plate. The machine vision camera is mounted on the movable block. Visual inspection component two has the same structure as visual inspection component one. In visual inspection component two, the fixed plate is horizontally fixed to the top of the base, and the machine vision camera in visual inspection component two faces the side of the bearing cage on the top of the rotating disk. In visual inspection component one, the fixed plate is vertically fixed to the top of the base, and the machine vision camera in visual inspection component one faces the top of the bearing cage on the top of the fixed base. By manually rotating the rotating handle, the position of the movable block can be easily adjusted, thereby adjusting the distance between the machine vision camera and the bearing cage to be inspected. The cooperation of the sliding rod and the lead screw provides the machine vision camera with precise movement capability. By rotating the rotating handle, the operator can flexibly adjust the distance between the machine vision camera and the bearing cage according to the inspection requirements.

[0013] Preferably, the unloading assembly includes an unloading conveyor frame, which is horizontally fixed to one end of the top of the base. An unloading plate chain is driven onto the unloading conveyor frame, and a drive motor is installed at the bottom of the unloading conveyor frame to drive the unloading plate chain. Unloading baffles are installed on both sides of the top end of the unloading conveyor frame away from the base, and the distance between the two unloading baffles is adapted to the diameter of the bearing cage. The design of the unloading baffles provides additional safety during the conveying process. By adapting the baffle spacing to the diameter of the bearing cage, the unloading baffles can effectively constrain the position of the bearing cage, preventing it from deviating from the track or falling off during conveying due to vibration or other external forces.

[0014] Preferably, a mounting plate is fixed to the side of the unloading conveyor near the rotary table. A pushing electric cylinder is horizontally fixed to one side of the mounting plate. One end of the pushing electric cylinder is connected to a pushing plate via a push rod. A horizontal sliding rod is connected to the side of the push plate near the push rod. A sliding cylinder is embedded in the mounting plate, and the sliding rod slides in contact with the mounting plate through the sliding cylinder. A distribution plate is connected to the side of the unloading conveyor away from the mounting plate. One end of the distribution plate corresponds to the position of the mounting plate. The pushing plate can push the bearing cage on the unloading plate chain onto the distribution plate. The cooperation between the mounting plate and the pushing electric cylinder provides precise control for the pushing action. Through the precise drive of the pushing electric cylinder, the pushing plate can accurately push the bearing cage from the unloading plate chain onto the distribution plate. The sliding contact design of the sliding rod and the sliding cylinder provides stability and linearity for the movement of the pushing plate.

[0015] The beneficial effects of this invention are: (1) In this invention, the outer box flange deformation detection equipment for thrust ball bearing cage production achieves fully automated operation from loading to detection to unloading. The loading component drives the loading plate chain transmission through the loading drive motor to automatically transport the bearing cage to the designated position. The transfer component uses electric gripper one and electric gripper two to perform clamping and transfer operations, sending the bearing cage to the fixed seat and rotating disk for detection in sequence. Finally, it is transported out by the unloading component. The whole process does not require much manual intervention, which greatly improves the detection efficiency, reduces the error and time cost caused by manual operation, and can quickly and stably complete the detection tasks of a large number of bearing cages, meeting the needs of large-scale production.

[0016] (2) In this invention, the visual inspection components one and two of the thrust ball bearing cage outer box flange deformation detection equipment perform visual inspection from the top and side of the bearing cage, respectively. The machine vision camera can perform high-precision image acquisition on parts such as the flange of the bearing cage outer box, and analyze whether there are defects such as deformation or cracks in the flange through image processing technology. Furthermore, the structure of visual inspection components one and two is reasonably designed. The rotating handle can drive the lead screw to rotate and move the position of the movable block, thereby changing the distance between the machine vision camera and the bearing cage, realizing flexible adjustment of the detection distance to obtain clearer and more accurate images, ensuring the reliability of the detection results, effectively improving the accuracy and precision of the detection, helping to promptly discover and screen out unqualified products, and ensuring product quality.

[0017] (3) In this invention, the transfer component of the thrust ball bearing cage production outer box flange deformation detection equipment has an ingenious structural design, including left and right moving plates, front and rear moving plates, and a vertical plate. The left and right moving plates, front and rear moving plates, and vertical plate are moved by left and right translational drive cylinders, front and rear translational drive cylinders, and lifting drive cylinders, respectively, thereby achieving precise positioning and flexible movement of electric grippers one and two. The distance between electric grippers one and two is the same as the distance between the fixed seat and the rotating disk, ensuring stable clamping and accurate placement of the bearing cage during transfer. This stable transfer operation ensures a smooth transition of the bearing cage during the detection process, avoiding product damage or detection errors caused by improper transfer, improving the operational stability and reliability of the equipment, and ensuring the smooth progress of the entire detection process.

[0018] (4) In this invention, the overall structure of the thrust ball bearing cage production outer box flange deformation detection equipment is compact and reasonable. The feeding component and the unloading component are fixed at both ends of the top of the base, and a fixed seat, a rotating disk, a transfer component, and a vision inspection component are set in the middle. The components cooperate with each other to form an efficient working area. This layout not only makes full use of the limited space, making the equipment occupy a relatively small area and easy to install and arrange in the production workshop, but also ensures the smoothness of material transmission and operation by maintaining appropriate distances between the components. It reduces transmission delays or interference caused by excessively long or short distances, improves the overall operating efficiency and working efficiency of the equipment, and helps enterprises optimize production space and reduce production costs.

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] like Figures 1-7As shown, the thrust ball bearing cage production outer box flange deformation detection equipment of the present invention includes a base 1, a feeding assembly 2, a transfer assembly 3, and a discharging assembly 8. The base 1 serves as the basic support structure of the entire equipment, ensuring the overall stability of the equipment and the precise cooperation between the components. The feeding assembly 2 and the discharging assembly 8 are respectively fixed at both ends of the top of the base 1, making the input and output paths of materials clear and non-interfering. The feeding assembly 2 is responsible for conveying the bearing cage to be inspected into the equipment, while the discharging assembly 8 is used to convey the bearing cage after inspection to the subsequent process or collection area, realizing automated material flow and improving production efficiency. A fixed seat 4 and a rotatable turntable 5 are installed on the top of the base 1 between the feeding assembly 2 and the discharging assembly 8. The fixed seat 4 is used to stably place the bearing cage, providing a stable inspection platform for the vision inspection assembly 6. The rotating disk 5 allows the bearing cage to be displayed from all angles during inspection, facilitating inspection from different perspectives by the vision inspection component 7. This ensures comprehensiveness and accuracy of the inspection and avoids blind spots caused by the fixed position of the bearing cage. The transfer component 3, installed on one side of the top of the base 1, is responsible for transferring the bearing cages from the loading component 2 to the fixed seat 4, and then transferring the bearing cages from the fixed seat 4 to the rotating disk 5. Finally, it transfers the inspected bearing cages from the rotating disk 5 to the unloading component 8. The transfer component 3 allows the bearing cages to be flexibly transferred between different inspection positions, ensuring the continuity and efficiency of the inspection process. Vision inspection component 6 is installed on the side of the top of the base 1 away from the transfer component 3, corresponding to the fixed seat 4. Vision inspection component 7 is installed on the side of the top of the base 1 away from the transfer component 3, corresponding to the rotating disk 5. Vision inspection component 6 primarily inspects the top of the bearing cage on the fixed seat 4, while vision inspection component 7 inspects the sides of the bearing cage on the rotating disk 5. The dual-vision inspection assembly allows for inspection of the bearing cage from different angles, enabling a more comprehensive detection of deformation in the outer casing's flange, thus improving inspection accuracy and reliability. The rational layout and close coordination between the base 1, loading assembly 2, transfer assembly 3, fixed base 4, rotating disk 5, vision inspection assembly one 6 and vision inspection assembly two 7, and unloading assembly 8 enable the equipment to efficiently and accurately complete the inspection of thrust ball bearing cage outer casing flange deformation, significantly improving production efficiency and product quality control.

[0030] The transfer assembly 3 includes a left-right moving plate 302, a front-back moving plate 306, and a vertical plate 309. The left-right moving plate 302 moves left and right and is fitted onto the top of the base 1. The front-back moving plate 306 moves and is fitted onto the top of the left-right moving plate 302. The vertical plate 309 is vertically fixed to the top of the front-back moving plate 306. A lifting plate 311 is mounted on the side of the vertical plate 309 closest to the fixed seat 4 and the rotating disk 5. An electric gripper 314 and an electric gripper 315 are horizontally mounted on the side of the lifting plate 311 furthest from the vertical plate 309. The engagement of the left-right moving plate 302 with the top of the base 1 allows the entire transfer assembly 3 to move left and right on the base 1. This movement provides sufficient space for the transfer assembly 3 to accurately reach different positions such as the feeding assembly 2, the fixed seat 4, and the rotating disk 5, providing a basis for the transfer of the bearing cage. The front-back moving plate 306 is mounted on top of the left-right moving plate 302 and can move back and forth on the left-right moving plate 302. This design further increases the flexibility of the transfer component 3, allowing it to make fine adjustments in the forward and backward directions on top of left and right movements. This enables more precise alignment with each working position, ensuring that the bearing cage can be accurately gripped and placed. The upright plate 309 is vertically fixed to the top of the forward and backward moving plate 306, providing stable support for the lifting plate 311. The lifting mechanism between the lifting plate 311 and the upright plate 309 allows for vertical height adjustment of the electric grippers 314 and 315. This lifting function allows the electric grippers 314 and 315 to adjust according to the height requirements of the bearing cage at different positions, ensuring that they can accurately grip and release the bearing cage at the appropriate location, avoiding gripping failures or product damage due to height mismatch. The distance between electric gripper 314 and electric gripper 315 is the same as the distance between the fixed base 4 and the rotating disk 5, ensuring that electric gripper 314 and electric gripper 315 can operate simultaneously during the transfer process. When electric gripper 314 transfers the bearing cage on the fixed base 4 to the rotating disk 5, electric gripper 315 can simultaneously transfer the bearing cage on the rotating disk 5 to the unloading assembly 8, realizing the synchronous operation of gripping and transfer, which greatly improves the operating efficiency of the equipment.

[0031] In an optional embodiment of this example, the feeding assembly 2 includes a feeding conveyor frame 201 and a support leg 202. One end of the feeding conveyor frame 201 is fixed to the top of the base 1, and the support leg 202 is vertically supported on the bottom end of the feeding conveyor frame 201 away from the base 1. A feeding plate chain 203 is connected to the feeding conveyor frame 201 via gear transmission. A feeding drive motor 204 for driving the feeding plate chain 203 is installed at the bottom end of the feeding conveyor frame 201. Feeding baffles 205 are fixed on both sides of the top end of the feeding conveyor frame 201 away from the base 1. The distance between the two feeding baffles 205 is adapted to the diameter of the bearing cage being conveyed. By setting the feeding baffles 205, the position of the bearing cage can be effectively constrained, preventing it from deviating from the track due to vibration or other external forces during the conveying process, thereby avoiding the bearing cage from falling off. The setting of the feeding baffles 205 not only improves the safety of the conveying process, but also ensures that the bearing cage can enter the subsequent inspection stage in the correct posture. The feeding assembly 2, through the rational coordination of the feeding conveyor frame 201, support legs 202, feeding plate chain 203, feeding drive motor 204, and feeding baffle 205, achieves efficient and stable feeding of bearing cages. This ensures the safety and stability of the bearing cages during the conveying process and provides a high-quality material supply for subsequent testing procedures.

[0032] In one optional embodiment of this invention, a retaining frame 206 is installed at the top of the feeding conveyor 201 near the base 1. The retaining frame 206 has an inverted "U" shape, and a retaining drive cylinder 207 is vertically fixed in the middle of the retaining frame 206. The bottom of the retaining drive cylinder 207 is connected to a retaining plate 208 via a push rod. In actual production, the transfer component 3 needs a certain amount of time to complete the clamping and transfer operation of the bearing cage. By temporarily retaining the bearing cage on the conveyor belt with the retaining frame 206, sufficient time can be provided for the operation of the transfer component 3, ensuring that it can accurately clamp the bearing cage at the appropriate position and time, thereby ensuring the continuity and efficiency of the entire inspection process.

[0033] In an optional embodiment of this example, the transfer assembly 3 further includes a left-right translation drive cylinder 304 that moves the left-right moving plate 302, a front-back translation drive cylinder 308 that moves the front-back moving plate 306, and a lifting drive cylinder 313 that moves the lifting plate 311. The left-right translation drive cylinder 304 is horizontally mounted on the top of the base 1, and one end of the left-right translation drive cylinder 304 is connected to the left-right moving plate 302 via a push rod. The front-back translation drive cylinder 308 is horizontally mounted on the top of the left-right moving plate 302, and one end of the front-back translation drive cylinder 308 is connected to the front-back moving plate 306 via a push rod. The lifting drive cylinder 313 is vertically mounted on one side of the upright plate 309 near the top, and the bottom of the lifting drive cylinder 313 is connected to the lifting plate 311 via a push rod. This multi-dimensional movement coordination system provides the transfer assembly 3 with extremely high flexibility and precision. Through the coordinated operation of the left-right translation drive cylinder 304, the front-back translation drive cylinder 308, and the lifting drive cylinder 313, the transfer assembly 3 can perform precise positioning and movement in three-dimensional space. This allows the transfer assembly 3 to accurately transfer the bearing cage from the loading assembly 2 to the fixed seat 4, then from the fixed seat 4 to the rotary table 5, and finally transfer the inspected bearing cage to the unloading assembly 8. Each step is achieved through precise electric cylinder drive and the cooperation of the slide rail slider, ensuring the accuracy and reliability of the operation. A first slide rail 301 is horizontally fixed to one side of the top of the base 1. A first slider 303, which slides and engages with the first slide rail 301, is fixed to the bottom of the left and right sliding plates 302. A second slide rail 305 is horizontally fixed to the top of the left and right sliding plates 302. A second slider 307, which slides and engages with the second slide rail 305, is fixed to the bottom of the front and rear sliding plates 306. A third slide rail 310 is vertically fixed to the side of the upright plate 309 near the lifting plate 311. A third slider 312, which slides and engages with the third slide rail 310, is fixed to the side of the lifting plate 311 near the upright plate 309. The design of the slide rails and sliders also has the functions of shock absorption and guidance. During movement, the slide rails and sliders can effectively reduce direct friction between mechanical parts, reduce wear, and extend the service life of the equipment. At the same time, the guiding function of the slide rails and sliders ensures the accuracy of the movement direction and avoids positioning inaccuracies caused by mechanical errors.

[0034] In one optional embodiment of this invention, a base 402 is fixed to the top of the base 1, and a fixing seat 4 is fixed to the top of the base 402. The presence of the base 402 provides a certain height for the fixing seat 4, making the overall layout of the inspection equipment more reasonable and facilitating the cooperation between the transfer component 3 and the vision inspection component 6 with the fixing seat 4. The fixing seat 4 has a cylindrical structure, and its internal diameter is adapted to the diameter of the bearing cage being inspected, allowing it to perfectly accommodate the bearing cage to be inspected. This precise dimensional matching ensures that the bearing cage can be stably placed within the fixing seat 4 without shaking or tilting. The fixing seat 4 has two convenient slots 401 for easy placement and removal, greatly facilitating the placement and removal of the bearing cage. In actual operation, the electric gripper of the transfer component 3 can easily insert or remove the bearing cage from the fixing seat 4 through the slots 401.

[0035] In one optional embodiment of this example, a mounting base 501 is embedded in the top of the base 1, and the rotating disk 5 is rotatably fitted on the top of the mounting base 501. A rotary drive motor 502 for driving the rotating disk 5 is installed at the bottom of the mounting base 501. By precisely controlling the speed and rotation angle of the rotary drive motor 502, precise driving of the rotating disk 5 can be achieved. The rotational fit design of the rotating disk 5 allows the bearing cage to be rotated and displayed in all directions during the inspection process. This design is crucial for the inspection of the vision inspection component 2 7, because only when the bearing cage can rotate in all directions can the vision inspection component 2 7 perform comprehensive inspection of its outer box flange and other parts from different angles.

[0036] In one optional embodiment of this example, the vision inspection component 6 includes a fixed plate 601, a movable block 605, and a machine vision camera 606. A slide rod 602 is fixed to one side of the fixed plate 601, and a lead screw 603 is rotatably engaged with it. The movable block 605 is sleeved on the slide rod 602, and the movable block 605 is threadedly engaged with the lead screw 603. A rotating handle 604 connected to the lead screw 603 is installed at the end of the fixed plate 601. The machine vision camera 606 is mounted on the movable block 605. The vision inspection component 7 has the same structure as the vision inspection component 6. The fixed plate 601 in the vision inspection component 7 is horizontally fixed to the top of the base 1, and the machine vision camera 606 in the vision inspection component 7 faces the bearing cage side of the top of the rotating disk 5. The fixed plate 601 in the vision inspection component 6 is vertically fixed to the top of the base 1, and the machine vision camera 606 in the vision inspection component 6 faces the top of the bearing cage of the fixed seat 4. By manually rotating the handle 604, the position of the movable block 605 can be easily adjusted, thereby adjusting the distance between the machine vision camera 606 and the bearing cage under inspection. The cooperation of the slide bar 602 and the lead screw 603 provides the machine vision camera 606 with precise movement capability. By rotating the handle 604, the operator can flexibly adjust the distance between the machine vision camera 606 and the bearing cage according to the inspection requirements, thereby obtaining the optimal inspection angle and image quality. This adjustability greatly improves the flexibility and adaptability of the inspection.

[0037] In an optional embodiment of this invention, the unloading assembly 8 includes an unloading conveyor frame 801, which is horizontally fixed to one end of the top of the base 1. An unloading plate chain 802 is driven onto the unloading conveyor frame 801, and a drive motor 803 is installed at the bottom of the unloading conveyor frame 801 to drive the unloading plate chain 802. Unloading baffles 804 are installed on both sides of the top end of the unloading conveyor frame 801 away from the base 1, and the distance between the two unloading baffles 804 is adapted to the diameter of the bearing cage. The design of the unloading baffles 804 provides additional safety assurance during the conveying process. By adapting the baffle spacing to the diameter of the bearing cage, the unloading baffles 804 can effectively constrain the position of the bearing cage, preventing it from deviating from the track or falling during conveying due to vibration or other external forces. This design not only improves the safety of conveying but also ensures that the bearing cage can enter the subsequent process or collection area in the correct posture, improving the reliability of the entire production process.

[0038] In one optional embodiment of this invention, a mounting plate 806 is fixed to the side of the unloading conveyor 801 near the rotary disk 5. A pushing electric cylinder 809 is horizontally fixed to one side of the mounting plate 806. One end of the pushing electric cylinder 809 is connected to a pushing plate 808 via a push rod. A horizontal sliding rod 807 is connected to the side of the pushing plate 808 near the push rod. A sliding cylinder is embedded in the mounting plate 806, and the sliding rod 807 slides in cooperation with the mounting plate 806 through the sliding cylinder. A separating plate 805 is connected to the side of the unloading conveyor 801 away from the mounting plate 806. One end of the separating plate 805 corresponds to the position of the mounting plate 806. The push plate 808 can push the bearing retainer on the unloading plate chain 802 onto the separating plate 805. The cooperation between the mounting plate 806 and the pushing electric cylinder 809 provides precise control for the pushing action. Driven precisely by the electric pusher cylinder 809, the pusher plate 808 accurately pushes the bearing cage from the unloading chain 802 onto the sorting plate 805. The sliding fit design of the slide rod 807 and the slide cylinder provides stability and linearity to the movement of the pusher plate 808. This design reduces friction and wobbling during movement, ensuring that the pusher plate 808 can move smoothly along the predetermined trajectory. Through its rational structural design and the coordinated work of its components, the unloading assembly 8 provides efficient screening and classification functions for the thrust ball bearing cage inspection equipment.

[0039] In operation, the feeding conveyor 201 of the feeding assembly 2 first transports the bearing cage from one end to the other via the feeding plate chain 203 on its top. The feeding plate chain 203 is driven by the feeding drive motor 204, achieving smooth transport through gear transmission. During transport, the feeding baffle 205 constrains the position of the bearing cage, preventing it from slipping or shifting during transport. When the bearing cage approaches the end of the feeding conveyor 201 near the base 1, the interception drive cylinder 207 on the interception frame 206 lowers the interception plate 208 via a push rod, temporarily intercepting the bearing cage on the conveyor belt, providing a time buffer for the transfer assembly 3 to pick up the parts. Subsequently, the transfer assembly 3 begins operation. The left and right translation drive cylinder 304 drives the left and right moving plate 302 to move along the first slide rail 301, moving the electric gripper 314 of the transfer assembly 3 above the feeding conveyor 201. At this point, the forward and backward translation drive cylinder 308 drives the forward and backward moving plate 306 to move along the second slide rail 305, so that the electric gripper 314 is precisely aligned with the bearing cage retained on the conveyor belt. Next, the lifting drive cylinder 313 drives the lifting plate 311 to descend along the third slide rail 310, so that the electric gripper 314 grips the bearing cage. After gripping, the lifting drive cylinder 313 drives the lifting plate 311 to rise, lifting the bearing cage from the loading conveyor 201. This structural coordination ensures that the bearing cage can be smoothly and accurately transferred from the loading area to the gripper of the transfer component 3, laying the foundation for subsequent inspection work. Through precise drive cylinder control and the guiding action of the slide rail slider, the entire loading and initial positioning process is efficient and stable, reducing manual intervention and improving production efficiency.

[0040] The equipment is equipped with a PLC controller (model: Mitsubishi FX3U-48MR; manufacturer: Mitsubishi Electric). The PLC controller controls the start and stop of the feeding drive motor 204 to achieve smooth transmission of the feeding plate chain 203. When the interception drive cylinder 207 of the interception rack 206 detects that the bearing retainer has reached the designated position, the PLC controller controls the interception plate 208 to descend, temporarily intercepting the bearing retainer and providing a time buffer for the picking operation of the transfer component 3. The PLC controller controls the left and right translation drive cylinder 304, the forward and backward translation drive cylinder 308, and the lifting drive cylinder 313 to achieve precise positioning and movement of the electric gripper 1 314 and electric gripper 2 315. According to the preset program, the PLC controller precisely controls the extension and retraction of the cylinders to ensure that the bearing retainer can be smoothly transferred between different detection positions. The PLC controller receives the detection signal from the machine vision camera 606 and controls the subsequent classification operation based on the detection results. If a defect is detected in the bearing cage, the PLC controller will mark the bearing cage and classify it during subsequent unloading. The PLC controller controls the pusher cylinder 809 based on the inspection results from the vision inspection components. If the bearing cage passes inspection, the PLC controller controls the unloading chain 802 to continue conveying it; if a defect is detected, the PLC controller controls the pusher cylinder 809 to push the bearing cage onto the sorting plate 805. Specifically, vision inspection components 6 and 7 send their inspection results (pass or fail) to the PLC controller during the inspection process. When the bearing cage reaches the unloading component 8, the PLC controller controls the pusher cylinder 809 based on the marking. If marked as fail, the pusher cylinder 809 pushes the bearing cage onto the sorting plate 805; if marked as pass, the bearing cage continues to be conveyed along the unloading chain 802 to the subsequent process or collection area.

[0041] Then, firstly, after the electric gripper 314 of the transfer assembly 3 picks up the bearing cage, the left-right translation drive cylinder 304 and the front-back translation drive cylinder 308 work together to transfer the bearing cage above the fixed seat 4. At this time, the lifting drive cylinder 313 drives the lifting plate 311 to descend, placing the bearing cage in the fixed seat 4. The fixed seat 4 has a cylindrical structure with an internal diameter that matches the diameter of the bearing cage, ensuring that the bearing cage can be stably placed inside it. The slot 401 on the fixed seat 4 facilitates the picking and putting away of the bearing cage, further improving the convenience of operation. Subsequently, the vision inspection assembly 6 begins to work. The machine vision camera 606 is mounted on the movable block 605. By rotating the screw 603 through the handle 604, the position of the movable block 605 on the slide bar 602 can be adjusted, thereby adjusting the distance between the machine vision camera 606 and the bearing cage to ensure the best inspection angle. Machine vision camera 606 performs visual inspection of the top of the bearing cage from the top of the mounting base 4, analyzing whether there are deformations or other defects in parts such as the outer casing flange. After the top inspection is completed, the electric gripper 314 of the transfer assembly 3 picks up the bearing cage from the mounting base 4 and transfers it to the rotating disk 5. The rotating disk 5 is mounted on the mounting base 501 through a rotational fit at its top and is driven to rotate by the rotary drive motor 502. After the bearing cage is placed on the rotating disk 5, the rotary drive motor 502 drives the rotating disk 5 to rotate, allowing the bearing cage to be displayed from all directions. At the same time, machine vision camera 606 in the vision inspection assembly 7 performs visual inspection of the bearing cage on the rotating disk 5 from the side. Through the rotation of the rotating disk 5, the vision inspection assembly 7 can perform comprehensive inspection of parts such as the outer casing flange of the bearing cage from different angles, further ensuring the comprehensiveness and accuracy of the inspection. The structural design and collaborative work of this stage ensure that the bearing cage can be smoothly transferred from the mounting base 4 to the rotating disk 5, and that top and side visual inspections are performed at two inspection positions respectively. With precise drive control and a stable mechanical structure, the testing process is efficient and reliable, enabling timely detection of defects in the bearing cage and ensuring product quality.

[0042] Step 3: As the electric gripper 314 of the transfer assembly 3 picks up the bearing cage from the fixed base 4 and transfers it to the rotating disk 5, the electric gripper 315 of the transfer assembly 3 simultaneously picks up the inspected bearing cage from the rotating disk 5 and transfers it to the unloading conveyor 801 of the unloading assembly 8 for conveying. The unloading conveyor 801 is horizontally fixed to one end of the top of the base 1, and the unloading conveyor 802 is driven by the unloading drive motor 803. The surface design of the unloading conveyor 802 is suitable for supporting the bearing cage, ensuring its stability and preventing slippage during conveying. A mounting plate 806 is fixed to the side of the unloading conveyor 801 near the rotating disk 5, and a pusher cylinder 809 is horizontally fixed to one side of it. The pusher cylinder 809 is connected to a pusher plate 808 via a push rod. A horizontal slide bar 807 is connected to the side of the pusher plate 808 closest to the push rod. The slide bar 807 slides against the mounting plate 806 via a sliding cylinder. This design ensures that the pusher plate 808 can move smoothly in the horizontal direction. Based on the inspection results of the vision inspection component, if the bearing cage is defective, the pusher cylinder 809 drives the pusher plate 808 to move along the slide bar 807, pushing the bearing cage on the unloading chain 802 onto the sorting plate 805. The sorting plate 805 is connected to the side of the unloading conveyor 801 away from the mounting plate 806, with one end corresponding to the position of the mounting plate 806. The sorting plate 805 provides a temporary storage location for the screened bearing cages, facilitating subsequent collection or processing. If the bearing cage passes inspection, it is directly conveyed to the subsequent process or collection area via the unloading chain 802 on the unloading conveyor 801. Discharge baffles 804 are installed on both sides of the top of the unloading conveyor 801, away from the base 1. The distance between the two discharge baffles 804 is adapted to the diameter of the bearing cage. This design effectively constrains the position of the bearing cage, preventing it from slipping or shifting during conveying and ensuring the stability of the conveying process. The structural design and collaborative operation at this stage ensure that the bearing cages after inspection can be accurately classified and conveyed to the designated position according to the inspection results. Through precise electric cylinder control and a stable mechanical structure, the unloading and classification process is efficient and reliable, which not only improves production efficiency but also enhances product quality control through classification management.

A device for detecting flange deformation of the outer casing in the production of a thrust ball bearing cage according to any one of claims 1-9, characterized in that: The specific steps involved in using the equipment for detecting flange deformation of the outer casing used in the production of thrust ball bearing cages are as follows: Step 1: The feeding conveyor (201) of the feeding assembly (2) transports the bearing retainer from one end to the other via the feeding plate chain (203) on its top. The feeding plate chain (203) is driven by the feeding drive motor (204) and achieves smooth transportation through gear transmission. During the transportation process, the feeding baffle (205) constrains the position of the bearing retainer. When the bearing retainer approaches the end of the feeding conveyor (201) near the base (1), the interception drive cylinder (207) on the interception frame (206) controls the interception plate (208) to descend through the push rod, temporarily intercepting the bearing retainer on the conveyor belt, providing a time buffer for the picking operation of the transfer assembly (3). The transfer assembly (3) starts working, and the right translation drive electric... The cylinder (304) drives the left and right moving plate (302) to move along the first slide rail (301) and move the electric gripper (314) of the transfer component (3) above the feeding conveyor (201). At this time, the front and back translation driving cylinder (308) drives the front and back moving plate (306) to move along the second slide rail (305) so that the electric gripper (314) is aligned with the bearing retainer stuck on the conveyor belt. Then, the lifting driving cylinder (313) drives the lifting plate (311) to descend along the third slide rail (310) so that the electric gripper (314) can clamp the bearing retainer. After clamping, the lifting driving cylinder (313) drives the lifting plate (311) to rise and lift the bearing retainer from the feeding conveyor (201). Step 2: After the electric gripper 1 (314) of the transfer component (3) grips the bearing cage, the left-right translation drive cylinder (304) and the front-back translation drive cylinder (308) work together to transfer the bearing cage to the top of the fixed seat (4). At this time, the lifting drive cylinder (313) drives the lifting plate (311) to descend and place the bearing cage in the fixed seat (4). The vision inspection component 1 (6) starts to work. The machine vision camera (606) is mounted on the movable block (605). By rotating the screw (603) through the handle (604), the position of the movable block (605) on the slide bar 1 (602) can be adjusted to adjust the distance between the machine vision camera (606) and the bearing cage. The machine vision camera (606) moves from the fixed seat. (4) Visual inspection of the top of the bearing cage is performed to analyze whether there are deformations or other defects in the outer box flange and other parts. After the top inspection is completed, the electric gripper (314) of the transfer component (3) clamps the bearing cage from the fixed seat (4) and transfers it to the rotating disk (5). The rotating disk (5) is mounted on the mounting seat (501) by the rotation of its top and is driven to rotate by the rotary drive motor (502). After the bearing cage is placed on the rotating disk (5), the rotary drive motor (502) drives the rotating disk (5) to rotate so that the bearing cage can be displayed in all directions. At the same time, the machine vision camera (606) in the visual inspection component (7) performs visual inspection of the bearing cage on the rotating disk (5) from the side. Step 3: When the electric gripper 1 (314) of the transfer component (3) picks up the bearing cage from the fixed seat (4) and transfers it to the rotating disk (5), the electric gripper 2 (315) of the transfer component (3) simultaneously picks up the inspected bearing cage from the rotating disk (5) and transfers it to the unloading conveyor (801) of the unloading component (8) on the unloading plate chain (802) for transmission. According to the inspection results of the visual inspection component, if the bearing cage has defects, the pusher cylinder (809) drives the pusher plate (808) to move along the slide bar 2 (807) to push the bearing cage on the unloading plate chain (802) onto the sorting plate (805). If the bearing cage passes the inspection, it is directly transported to the subsequent process or collection area through the unloading plate chain (802) on the unloading conveyor (801).
