Description

Technical Field

[0001] The invention relates to the technical field of bearing conveying, and in particular to an adjustable bearing processing feed conveying device and method. Background Art

[0002] In the bearing processing, conveying is an important link to ensure the smooth progress of the production process. Parts in different states need to be conveyed between different processing steps, including conveying bearing rings and balls that have completed surface treatment and meet high-precision requirements from super-finishing to assembly stations. When conveying balls, vibration plates are usually used for conveying. When conveying balls of various sizes, it is often necessary to purchase multiple vibration plates, which is too costly. At present, there are also vibration plates with adjustable guide plates, but when adjusting, they are only contracted at the discharge end, so that a large amount of material will gather in the guide plate, resulting in more additional friction between balls and between balls and hoppers, which ultimately affects the accuracy of the bearing after assembly; For example, the vibrating plate based on the hopper and spiral track adjustable disclosed by announcement number CN103466268B can adjust the diameter of the hopper, the pitch of the spiral track and the total height, but it needs to loosen and tighten the bolts. The whole adjustment process takes a long time, which affects the overall processing efficiency of the bearing. The adjustable vibrating plate disclosed by announcement number CN219928734U does not need to be adjusted by loosening and tightening the bolts, but it only shrinks at the discharge end so that a large amount of material will gather in the guide plate, resulting in more additional friction between the balls and between the balls and the hopper, which ultimately affects the accuracy of the assembled bearing. Therefore, an adjustable bearing processing feed conveying device and method are proposed. Summary of the invention

[0014] The present invention provides an adjustable bearing processing feed conveying device and method. Compared with the prior art, it has the following beneficial effects: (1) The adjustable bearing processing feeding and conveying device and method puts the balls to be conveyed to the assembly process into a hopper and starts the vibrating feed plate. When vibrating, the balls can be conveyed to the assembly process in an orderly manner along the guide plate. By adjusting the passable diameter of the guide plate, when the production line needs to process balls of different models, the guide plate diameter can be quickly adjusted to reduce downtime and conversion costs.

[0015] (2) The adjustable bearing processing feed conveying device and method utilizes an alternating magnetic field to detect whether there are defects on the surface of the balls required for bearing assembly during the process of conveying the balls through the machine body. By ensuring that each ball passes through the center of the circle formed by the fixed arc block and the sliding arc block, a consistent and controllable detection environment can be provided, thereby improving the repeatability and reliability of the detection results, and improving the quality and efficiency of the detection. The ability of the guide plate to change with the ball diameter enables the detection component to quickly adapt to balls of different models and sizes, thereby improving the flexibility of the production line, ensuring that the surface of the conveyed balls is intact, and significantly improving the overall production efficiency and product quality.

[0016] (3) The adjustable bearing processing feeding and conveying device and method, when the ball passes through the detection component for surface defect detection, if the surface of the ball is defect-free, it is directly conveyed to the next process for assembly; if the surface of the ball is defective, the ball with the surface defect is discharged to the outside of the machine body through the discharge component; it can ensure that any ball detected to have a surface defect can be discharged from the vibration plate in a timely and accurate manner, thereby ensuring the quality consistency of the final product. The discharge component can automatically adjust according to the change of the guide plate diameter, so that the entire system can quickly adapt to balls of different models and sizes, without the need for frequent replacement or adjustment of equipment, thereby ensuring the continuity and stability of production, and reducing waste in subsequent processing by accurately removing defective products and reducing material costs.

The expansion rope 27 slides against a guide nose 28, and the expansion rope 27 transmits power to make the vertical rods 24 on both sides move synchronously. One end of the guide nose 28 is fixedly mounted on the support plate 25 on the side to guide and limit the expansion rope 27. One end of the guide rod 29 is fixedly mounted on the side plate 2 to guide and limit the side plate 2; One end of the limit plate 210 is fixedly mounted on the guide plate 12 to guide and limit the guide rod 29, and one end of the guide rod 29 is slidably inserted into the limit plate 210; One end of the spring 1 211 is fixedly mounted on the guide rod 29, and the other end of the spring 1 211 is fixedly mounted on the limit plate 210 to provide elastic force for restoring the guide rod 29; The guide rail 5 is located at one end of the guide plate 12 to limit the moving direction of the ball. The guide rail 5 consists of two left and right guide rails, one of which is fixedly installed at the end of the guide plate 12, and a connecting rod 51 is fixedly installed at the bottom of the other guide rail 5. The other end of the connecting rod 51 is fixed on the guide rod 29 to assist in changing the spacing between the guide rails 5.

[0022] When in use, the balls to be transported to the assembly process are placed in the hopper 11, and the vibrating feed tray body 1 is started. The balls can be transported to the assembly process in an orderly manner along the guide plate 12 during vibration. At the same time, a side plate 2 is provided on the side wall of the guide plate 12 to prevent the balls from falling off the guide plate 12 during vibration transportation. When assembling bearings of different types, it is necessary to convey balls of different specifications. At this time, the control console starts the adjusting push rod 26, and the adjusting push rod 26 drives the vertical rod 24 to move to the side where the outside of the machine body 1 is located. Through the sliding cooperation between the vertical rod 24 and the support plate 25, the vertical rod 24 can only move linearly along the support plate 25 under the drive of the adjusting push rod 26, and the vertical rod 24 simultaneously drives the support rod 23 to move, and the support rod 23 simultaneously drives the middle plate 21 to move, and the middle plate 21 drives the limit block 22 to move, through the sliding cooperation between the limit block 22 and the side plate 2, and at the same time, a guide rod 29 is fixed at each end of the side plate 2, and through the sliding cooperation between the guide rod 29 and the limit plate 210, the guide rod 29 can only move linearly along the limit plate 210, and the spring 1 211 provides the guide rod 29 with sliding to the side where the limit plate 210 is located. At the same time, under the restriction of the limit plate 210, the side plate 2 can only move linearly; At the same time, the vertical rod 24 will drive the expansion rope 27 to move during the movement, and the expansion rope 27 is guided and limited by the guide nose 28, so that when the vertical rod 24 on the side of the adjustment push rod 26 moves, it can drive the vertical rod 24 on the side of the guide nose 28 to move in the opposite direction. In order to further ensure that the vertical rod 24 on the side of the guide nose 28 can be reset to its original position, a spring 4 is added between the vertical rod 24 on the side where the guide nose 28 is located and the support plate 25 to provide elastic force for the vertical rod 24 on this side to move away from the side where the guide nose 28 is located; The side plate 2 as a whole is synchronously moved toward the side where the outside of the machine body 1 is located under the drive of multiple intermediate plates 21, so that the diameter of the ball that can be accommodated by the guide plate 12 can be changed, and it is switched to the diameter of the ball used by the required assembly model bearing. At the same time, the connecting rod 51 is synchronously driven to move through the guide rod 29, and the connecting rod 51 drives the guide rail 5 to move, and the interval between the two guide rails 5 is synchronously changed. The push rod 26 is controlled and adjusted by the console to stop at this position until the next switch is made.

[0023] Embodiment 2, the technical solution of this embodiment is different from that of embodiment 1 in that: a detection assembly for detecting the surface state of the ball is arranged in the hopper 11, and the detection assembly includes: a fixed arc block 3, a sliding arc block 31, a switching plate 32, a switching rope 33, a positioning plate 34, a power rope 35, a guide column 36, a fixed rod 37, a second spring 38, a positioning block 39, a sliding sleeve 310, and a sliding rod 311; The fixed arc block 3 has a copper wire inside, and a mounting plate is fixedly installed on the side wall of the fixed arc block 3, and one end of the mounting plate is fixedly installed on the hopper 11 to provide support for the fixed arc block 3; A circular ring is formed between the sliding arc block 31 and the fixed arc block 3 to detect surface defects of the ball. The copper wire is slidably wound in the fixed arc block 3 and the sliding arc block 31 to form a coil, and one end of the copper wire is fixedly installed in the fixed arc block 3; One end of the switching plate 32 is fixedly mounted on the side walls of the fixed arc block 3 and the sliding arc block 31 to assist in changing the diameter of the ring; One end of the switching rope 33 is slidably inserted into the switching plate 32 to transmit the power for changing the diameter of the ring; The outer wall of the positioning plate 34 is fixedly connected to both ends of the switching rope 33 to transmit the power for changing the diameter of the ring; One end of the power rope 35 is fixedly mounted on the side wall of the positioning plate 34 to transmit the power for changing the diameter of the ring; The bottom of the guide column 36 is fixedly installed in the hopper 11 to guide and limit the power rope 35, and the power rope 35 is slidably connected to the guide column 36; One end of the fixing rod 37 is fixedly installed on the top of the fixing arc block 3 to assist the ring to reset, and the bottom of the fixing plate is fixedly installed on the top of one of the sliding arc blocks 31 to assist the ring to reset; One end of the second spring 38 slides against the side wall of the fixing rod 37 to provide power for the ring to reset, and the other end of the second spring 38 is fixedly mounted on the fixing plate; One end of the positioning block 39 is fixedly mounted on the side walls of the fixed arc block 3 and the sliding arc block 31 to provide support for the sliding arc block 31; One end of the sliding sleeve 310 is slidably inserted into the positioning block 39 to provide support for the sliding arc block 31; One end of the sliding rod 311 is slidably inserted into the sliding sleeve 310 to provide support for the sliding arc block 31; The positioning block 39 installed on the fixed arc block 3 provides support for the sliding sleeve 310, the sliding sleeve 310 provides support for the sliding rod 311, and the sliding rod 311 provides support for the positioning block 39 installed on the sliding arc block 31 and the sliding arc block 31.

[0024] When in use, during the process of conveying the balls required for bearing assembly through the machine body 1, the fixed arc block 3 and the sliding arc block 31 are covered outside the guide rail 5, and copper wire is wound inside the fixed arc block 3 and the sliding arc block 31, and alternating current is passed through the copper wire to form an alternating magnetic field. The alternating magnetic field induces eddy currents inside the material. When the balls pass through the alternating magnetic field, if there are defects such as cracks, scratches, holes, etc. on the surface or near the surface of the balls, these defects will change the path of the eddy currents, resulting in changes in the eddy current density. The eddy currents will also generate a secondary magnetic field, which in turn affects the original alternating magnetic field and is ultimately reflected in the change in the resistance of the coil. The detection instrument connected to the coil can measure this impedance change and convert it into an interpretable electrical signal, thereby determining whether there are defects on the surface of the conveyed balls and their location, size, and other information; When the adjusting component is being adjusted, the vertical rod 24 synchronously drives the power rope 35 to move, and the power rope 35 slides with the guide column 36, so that the power rope 35 drives the positioning plate 34 to move to the side close to the guide column 36, and drives the switching rope 33 to move synchronously through the positioning plate 34, and the switching rope 33 slides with the switching plate 32, so that the switching rope 33 drives the switching plate 32 to shrink toward the axis of the fixed arc block 3, and the switching plate 32 drives the sliding arc block 31 to shrink synchronously, so that the diameter of the circle formed by the fixed arc block 3 and the sliding arc block 31 changes. In the process of shrinking the sliding arc block 31, since one end of the copper wire is fixedly connected to the inner wall of the fixed arc block 3, the other end of the copper wire slides through the fixed arc block 3 and the sliding arc block 31. When the sliding arc block 31 shrinks, one end of the copper wire is fixed, and the sliding end slides along the curvature of the fixed arc block 3 and the sliding arc block 31, so that the number of windings of the copper wire changes, so that the detection sensitivity of the detection component is adaptively changed; During the contraction of the sliding arc block 31, the sliding arc block 31 synchronously drives the positioning block 39 to move, and the positioning block 39 drives the sliding sleeve 310 to move. The sliding sleeve 310 and the sliding rod 311 slide together, so that the sliding arc block 31 can be supported and can change with the operation of the adjustment component. The fixed arc block 3 provides support force to the fixed rod 37, and a spring 2 38 is installed between the fixed rod 37 and the fixed plate, so that the sliding arc block 31 moves from the retracted position to the Figure 7 During the process of resetting to the maximum position shown, the spring 2 38 provides elastic force to the fixed plate, so that the fixed plate drives the sliding arc block 31 at a symmetrical position with the fixed arc block 3 to move, so that the sliding arc block 31 drives the other two sliding arc blocks 31 to reset.

[0025] Embodiment 3, the technical solution of this embodiment is different from that of embodiment 2, including: a discharge assembly for discharging balls with surface defects is arranged in the hopper 11, and the discharge assembly includes: a discharge push rod 4, a left fixed frame 41, a sliding column 42, a right fixed frame 43, a spring 44, a baffle 45, a release plate 46, and a control rod 47; One end of the discharge push rod 4 is fixedly mounted on one end of the mounting rod, and one end of the mounting rod is fixedly mounted on the outside of the hopper 11 to provide power for the operation of the discharge assembly; The side wall of the left fixed frame 41 is fixedly mounted on the output end of the discharge push rod 4 to transmit the power required for the operation of the discharge assembly; One end of the sliding column 42 is slidably disposed in the left fixed frame 41, and the other end of the sliding column 42 is fixedly mounted with a right fixed frame 43; One end of the spring 3 44 is fixedly mounted on the left fixed frame 41, and the other end of the spring 3 44 is fixedly mounted on the right fixed frame 43. The spring 3 44 is slidably sleeved outside the sliding column 42, and the spring 3 44 provides power for the right fixed frame 43 to reset. One end of the baffle 45 is fixedly mounted on the right fixed frame 43 to block the ball bearings; The bottom of the release plate 46 is fixedly mounted on the top of the right fixed frame 43 to assist in discharging the balls with surface defects; One end of the control rod 47 is fixedly installed on the side wall of the hopper 11 to provide power to the discharge assembly. When the discharge push rod 4 drives the left fixed frame 41 and the right fixed frame 43 to move outside the hopper 11, the control rod 47 abuts against the release plate 46, so that the release plate 46 drives the right fixed frame 43 to move linearly along the sliding column 42. The distance between the movable parts of the two guide rails 5 increases, and it is impossible to provide support for the ball bearings, causing the ball bearings to fall.

[0026] When in use, when the ball passes through the inspection component for surface defect inspection, if the surface of the ball is free of defects, it is directly transported to the next process for assembly; If the surface of the ball is defective, the discharge push rod 4 is started by the control console, and the discharge push rod 4 drives the left fixed frame 41 to move, and the left fixed frame 41 drives the right fixed frame 43 to move, and the sliding column 42 and the left fixed frame 41 slide and cooperate, so that the right fixed frame 43 can only move in a straight line during the movement, and the right fixed frame 43 drives the movable part of the guide rail 5 to move, so that the ball with a defective surface is directly brought to the outside of the machine body 1 by the discharge assembly and falls into the collection box below (not shown in the figure). During the movement of the right fixed frame 43, it will synchronously drive the baffle 45 to move, so that after the right fixed frame 43 moves to the outside of the machine body 1, the baffle 45 can be blocked at the guide rail 5 located in the detection assembly, so as to prevent the balls behind from falling directly from the highest point at the notch of the guide rail 5 to the bottom of the hopper 11, and colliding with the remaining balls in the hopper 11 to cause unnecessary damage; When the adjustment component starts to adjust the whole, the fixed part of the guide rail 5 moves to the guide rail 5 on the side closer to the hopper 11 under the drive of the guide rod 29 and the connecting rod 51, and at the same time, the movable part of the guide rail 5 is squeezed by the protrusion of the connecting rod 51, and the right fixed frame 43 is driven to move by the movable part, and the right fixed frame 43 drives the sliding column 42 to move, so that the sliding column 42 moves in a straight line along the left fixed frame 41 to shrink as a whole, and at the same time, it does not affect the normal operation of the subsequent discharge component, and discharges the ball with surface defects to the outside of the machine body 1.

[0027] In another embodiment different from the aforementioned embodiment, the discharge push rod 4 is replaced with a servo motor, a rotating shaft, a gear, a rack and a limit column. The servo motor drives the rotating shaft to rotate, the rotating shaft drives the gear to rotate, the gear drives the rack to move, the limit column guides and limits the rack, and the rack drives the left fixed frame 41 to move, so that the discharge component is faster in the process of discharging and resetting, reducing the time required for discharging and improving the conveying efficiency.

[0028] The embodiment of the present invention also provides an adjustment method applicable to an adjustable bearing processing feed conveying device, comprising the following steps: S1, put the balls to be transported to the assembly process into the hopper 11, and control the operation of the machine body 1 through the console, so that the balls are transported in an orderly manner along the guide plate 12, the side plate 2, and the guide rail 5 under vibration; S2, performing surface defect detection on the balls conveyed to the guide rail 5 by means of a detection component; S3, using the discharge assembly to discharge the balls with surface defects out of the hopper 11; S4. When assembling bearings of different specifications, close the machine body 1, and use the console to control the operation of the adjustment component to change the position of the side plate 2, wherein the time required for the operation of the adjustment component is between 3-6 seconds; S5. After adjustment, the machine body 1 is controlled to run again through the console to convey the balls again.
