Description
Technical Field
[0001] This utility model relates to the field of powder metallurgy bearing cap production technology, and in particular to a bearing cap deburring device. Background Technology
[0002] Powder metallurgy is a highly efficient and energy-saving metal forming process that manufactures metal parts through processes such as powder preparation, pressing, sintering, and post-processing. Bearing caps, as a common mechanical structural component, are widely produced using powder metallurgy, offering significant advantages such as good dimensional consistency, high material utilization, and the ability to mass-produce complex shapes. However, during the pressing (molding) process, the metal powder flows and fills the mold cavity under high pressure, inevitably resulting in burrs on the surface of the part.
[0003] Although these burrs are microscopic, they pose significant risks: First, they affect the dimensional accuracy and assembly performance of parts, potentially causing bearing caps to fail to install accurately or creating installation gaps; second, burrs may fall off and become abrasive particles, entering the bearing system, accelerating the wear of bearings and mating parts, and reducing the reliability and lifespan of the entire transmission system; third, they affect the appearance quality of products and reduce market competitiveness.
[0004] Therefore, deburring is an indispensable and crucial process in the production of powder metallurgy bearing caps. Currently, deburring is generally done manually, with operators using simple tools such as files, scrapers, and sandpaper, relying on experience to remove burrs. This method is extremely inefficient, labor-intensive, and the quality of deburring depends entirely on the worker's skill level, making it difficult to guarantee consistency and unsuitable for large-scale automated production. Summary of the Invention
[0005] This invention addresses the shortcomings of existing technologies by providing a deburring device for bearing caps.
[0006] This utility model is achieved through the following technical solution: a bearing cover deburring device is provided, including a feeding mechanism, a discharging mechanism, a deburring mechanism located between the feeding mechanism and the discharging mechanism, and a pick-and-place mechanism that picks up the workpiece from the feeding mechanism, deburrs it through the deburring mechanism, and then sends it to the discharging mechanism; the deburring mechanism includes two rotatable brush rollers; the pick-and-place mechanism includes a moving block, a gripper that moves with the moving block and can pass between the two brush rollers, and a drive assembly that drives the moving block to move.
[0007] Preferably, both the feeding mechanism and the discharging mechanism are belt conveyors. The feeding mechanism transports the workpiece to be deburred to the discharging end of the feeding mechanism, the pick-and-place mechanism picks up the workpiece to be deburred, and after the deburring mechanism removes the burrs, it is sent to the feeding end of the discharging mechanism, and the deburred workpiece is sent away by the discharging mechanism.
[0008] Preferably, a baffle plate is provided at the discharge end of the feeding mechanism, and the baffle plate is fixed to the frame of the belt conveyor. After the workpieces conveyed by the feeding mechanism are delivered to the discharge end of the feeding mechanism, they will no longer move forward under the action of the baffle plate. The workpieces conveyed behind will be arranged in sequence. After the workpiece at the front is taken away by the pick-and-place mechanism, the workpieces behind will continue to move forward.
[0009] Preferably, the workpiece is a bearing cover with a protrusion in the middle and threaded holes at both ends, and the bearing cover is placed on the feeding mechanism and the discharging mechanism with both ends facing upwards. To facilitate stable conveying of the bearing cover, each belt conveyor includes two parallel belts and a support groove between the two belts. The protrusion in the middle of the bearing cover is placed in the support groove, and the two sides of the protrusion are placed on the two belts. The protrusion of the bearing cover is located in the support groove, realizing stable conveying of the bearing cover. To ensure the synchronization of the two belt conveyors, the two belts are driven by a coaxial belt roller at the same end and by the same motor.
[0010] Preferably, the two brush rollers are arranged vertically, and the central axis of both brush rollers is rotatably mounted on the support.
[0011] Preferably, the central shaft of one of the brush rollers is connected to the motor, and the central shafts of the two brush rollers are driven synchronously by a gear set.
[0012] Preferably, the drive assembly includes a lead screw, a guide rod parallel to the lead screw, and a drive motor for driving the lead screw to rotate.
[0013] Preferably, the two ends of the lead screw are rotatably connected to the column, the lead screw passes through the moving block and is threadedly connected to the moving block, and the guide rod passes through the moving block and its two ends are fixed to the column.
[0014] Preferably, a lifting cylinder that drives the gripper to move up and down is installed on the moving block.
[0015] Preferably, a bidirectional cylinder for opening or clamping the gripper is installed at the piston rod end of the lifting cylinder. The gripper includes two downward-facing vertical claws, each of which is connected to a piston rod of the bidirectional cylinder.
[0016] Preferably, when the grippers are open, the two vertical grippers can be inserted into the threaded holes at both ends of the bearing cover. After the two vertical grippers are inserted into the threaded holes, the bidirectional cylinder controls the two vertical grippers to move closer to each other to clamp the workpiece. By utilizing the two threaded holes on the original structure of the bearing cover through the gripper structure, the workpiece can be easily picked up and put down, and deburring of the workpiece can be achieved without dead angles, thus improving the deburring effect.
[0017] The beneficial effects of this utility model are as follows: 1. This utility model has a simple structure and a high degree of automation. It can efficiently remove burrs from the surface of powder metallurgy bearing covers, improve work efficiency, reduce the labor intensity of workers, and ensure the consistency and stability of processing quality.
[0018] 2. This utility model utilizes a gripper structure in conjunction with two threaded holes on the original structure of the bearing cover to facilitate the handling of workpieces while achieving deburring without dead angles, thus improving the deburring effect. Attached Figure Description

Detailed Implementation
[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0021] like Figure 1-4 As shown, this utility model includes a feeding mechanism 1, a discharging mechanism 2, a deburring mechanism 3 located between the feeding mechanism 1 and the discharging mechanism 2, and a picking and placing mechanism 4 that picks up workpieces from the feeding mechanism 1, deburrs them through the deburring mechanism 3, and then sends them to the discharging mechanism 2.
[0022] In this embodiment, both the feeding mechanism 1 and the discharging mechanism 2 are belt conveyors. The feeding mechanism 1 transports the workpiece to be deburred to the discharging end of the feeding mechanism 1. The pick-and-place mechanism 4 picks up the workpiece to be deburred, and after deburring by the deburring mechanism 3, it is sent to the feeding end of the discharging mechanism 2. The discharging mechanism 2 then sends the deburred workpiece away. In this embodiment, a baffle plate 11 is provided at the discharging end of the feeding mechanism 1. The baffle plate 11 is fixed to the belt conveyor frame. After the workpiece from the feeding mechanism 1 is transported to the discharging end of the feeding mechanism 1, it stops moving forward under the action of the baffle plate 11. The workpieces transported from behind are arranged in sequence. After the workpiece at the front is picked up by the pick-and-place mechanism 4, the workpieces behind continue to move forward.
[0023] In this embodiment, the workpiece is a bearing cover 5 with a protrusion in the middle and threaded holes at both ends. The bearing cover 5 is placed on the feeding mechanism 1 and the discharging mechanism 2 with both ends facing upwards. To facilitate the stable conveying of the bearing cover 5, each belt conveyor includes two parallel belts 12 and a support groove 13 located between the two belts 12. The protrusion in the middle of the bearing cover 5 is placed in the support groove 13, and the two sides of the protrusion are placed on the two belts 12. The protrusion of the bearing cover 5 is located in the support groove 13, realizing the stable conveying of the bearing cover 5. In order to ensure the synchronicity of the conveying of the two belts 12, the two belts 12 are driven by a coaxial belt roller at the same end and driven by the same motor.
[0024] The deburring mechanism 3 includes two rotatable brush rollers 31. In this embodiment, the two brush rollers 31 are arranged vertically, and the central shafts of the two brush rollers 31 are rotatably mounted on the support base 32. The central shaft of one of the brush rollers 31 is connected to a motor, and the central shafts of the two brush rollers 31 are driven synchronously by a gear set.
[0025] The material handling mechanism 4 includes a movable block 41, a gripper that moves with the movable block 41 and can pass between two brush rollers 31, and a drive assembly for driving the movable block 41. The drive assembly includes a lead screw 42, a guide rod 43 parallel to the lead screw 42, and a drive motor 44 for driving the lead screw 42 to rotate. The two ends of the lead screw 42 are rotatably connected to the column 45. The lead screw 42 passes through the movable block 41 and is threadedly connected to the movable block 41. The guide rod 43 passes through the movable block 41 and its two ends are fixed to the column 45.
[0026] A lifting cylinder 46, which drives the gripper to move up and down, is installed on the moving block 41. A bidirectional cylinder 47, which drives the gripper to open or close, is installed at the piston rod end of the lifting cylinder 46. The gripper includes two downward-facing vertical claws 48, each connected to a piston rod of the bidirectional cylinder 47. When the gripper is open, the two vertical claws 48 can be inserted into the threaded holes at both ends of the bearing cover 5. After the two vertical claws 48 are inserted into the threaded holes, the bidirectional cylinder 47 controls the two vertical claws 48 to move closer to each other to clamp the workpiece. By utilizing the two threaded holes on the original structure of the bearing cover 5 through the gripper structure, the workpiece can be easily picked up and put down, and deburring of the workpiece can be achieved without dead angles, thus improving the deburring effect.
[0027] In the specific operation, the drive motor 44 drives the lead screw 42 to rotate, causing the moving block 41 to move the gripper. The gripper moves to above the discharge end of the feeding mechanism 1 to pick up the workpiece. When picking up the workpiece, the lifting cylinder 46 controls the gripper to move down, and the bidirectional cylinder 47 controls the gripper to open. After the two vertical claws 48 are inserted into the threaded hole, the bidirectional cylinder 47 controls the two vertical claws 48 to move closer to each other to clamp the workpiece. The lifting cylinder 46 controls the gripper and the workpiece to move up, completing the workpiece pickup. The lead screw 42 rotates, causing the moving block 41 to move towards the discharge mechanism 2. After the workpiece passes between the two rotating brush rollers 31, the deburring is completed. The workpiece continues to move to above the feed end of the discharge mechanism 2. The lifting cylinder 46 drives its piston rod to extend, and the bidirectional cylinder 47 controls the two vertical claws 48 to move away from each other, causing the gripper to open. The workpiece falls onto the discharge mechanism 2 and is conveyed away by the discharge mechanism 2, completing the deburring of one workpiece.
[0028] This utility model has a simple structure and a high degree of automation. It can efficiently remove burrs from the surface of the powder metallurgy bearing cover 5, improve work efficiency, reduce the labor intensity of workers, and ensure the consistency and stability of processing quality.
