[0002] Powder metallurgy gears are made by pressing metal powder into shape through a high temperature and high pressure process, and then undergoing subsequent treatments such as sintering.

[0003] During the sintering process of powder metallurgy gear compacts, the gears shrink and deform, and their dimensional tolerance and surface roughness cannot meet the use requirements of the parts. It is necessary to improve the dimensional accuracy and surface roughness of the sintered parts through a finishing process. During the finishing process, a small amount of plastic deformation occurs on the surface layer of the gear, so that most of the gear deformation can be corrected. The chamfers, grooves and marks of the gears can also be solved by finishing methods.

[0004] The staff needs to place multiple gear sintered parts on the shaping device in turn, and the shaping device performs secondary pressing processing on the multiple gears in turn to meet the use requirements of the parts. However, when the staff performs a single loading action for a long time, the workload of the staff is increased, the processing efficiency of the gear sintered parts is reduced, the processing cycle of the gear sintered parts is extended, and the production cost of the gear sintered parts is increased.

There is no need for the staff to maintain a single feeding action for a long time, which reduces the workload of the staff, improves the processing efficiency of the powder metallurgy gear, shortens the processing cycle of the gear sintered parts, and thus reduces the production cost of the gear sintered parts.

[0008] Optionally, a grinder is connected to the base, and the grinder can grind the surface of the gear. The second robot can clamp the gear on the conveyor belt one and place it on the grinding end of the grinder. When the grinder completes grinding the gear, the second robot clamps the gear on the grinder and places it on the processing end of the shaping device.

[0009] By adopting the above technical solution, when conveyor belt one carries the gear close to the shaping device, robot arm two clamps the gear on conveyor belt one and places it on the grinding end of the grinder, and the grinder grinds the surface of the gear to complete the preliminary grinding of the gear. Robot arm two clamps the gear that has been grinded on the grinder and places it on the processing end of the shaping device, and the shaping device performs secondary pressing on the gear to further improve the processing accuracy and strength of the gear.

[0010] Optionally, it also includes a unloading component, which includes a conveyor belt 2 and a receiving tray, the conveyor belt 2 is connected to the surface of the base, the feeding end of the conveyor belt 2 faces the discharging end of the shaping device, the gear processed at the processing end of the shaping device falls into the surface of the conveyor belt 2 through the discharging end, the receiving tray is connected to the base, the conveyor belt 2 is located between the shaping device and the receiving tray, the receiving tray surface faces the discharging end of the conveyor belt 2, and the conveyor belt 2 carries the gear and is adjusted into the surface of the receiving tray.

[0011] By adopting the above technical solution, after the shaping device completes the secondary pressing of the gear, it falls from the discharge end onto the surface of conveyor belt 2. Conveyor belt 2 carries the gear toward the receiving tray. The receiving tray surface faces the discharge end of conveyor belt 2. The gear on conveyor belt 2 falls into the receiving tray surface due to its own gravity, thereby realizing the collection of the processed gear.

[0012] Optionally, the unloading assembly also includes a guide plate, which is connected to the surface of the base, and the guide plate is located between the discharge end of the conveyor belt and the receiving tray. The inclined height of the guide plate increases as the distance to conveyor belt 2 decreases, and the guide plate surface guides the gear of conveyor belt 2 to enter the surface of the receiving tray.

[0013] By adopting the above technical solution, when conveyor belt 2 carrying the gear slides toward the receiving tray, the guide plate surface guides the gear on conveyor belt 2 to enter the receiving tray surface, making it difficult for the gear to fall from the discharge end of conveyor belt 2, thereby ensuring the stability of the receiving tray in storing the gear that has completed the secondary pressing process.

[0014] Optionally, the receiving tray includes a tray body and a support body, the bottom of the support body is connected to the base surface, the tray body is rotatably connected to the top of the support body, the tray body surface faces the second discharge end of the conveyor belt, and the inner cavity of the tray body is used for storing gears.

[0015] By adopting the above technical solution, the disc body rotates on the top of the support body, and the gears at the two discharge ends of the conveyor belt fall into the disc body surface at intervals, making it difficult for the gears to accumulate on one side of the disc body and tip over, further improving the stability of the docking tray for gear storage.

Multiple gears are stacked in sequence and embedded in the positioning spaces, and the guide rod surfaces abut against the outer peripheral surfaces of the gears to form limit positions, so that the gears are not easily offset on the guide seat, thereby improving the accuracy of the robot in clamping the gears.

[0018] Optionally, the feeding seat includes a fixed column and a rotating ring, the fixed column is connected to the surface of the base, the rotating ring is coaxially rotatably connected to the outer peripheral surface of the fixed column, and the multiple guide seats are connected to the surface of the rotating ring at intervals around the axis of the fixed column. The feeding assembly also includes a lifting seat, a support plate and a plurality of positioning plates, the positioning plates correspond to the guide seats one by one, the surface of the positioning plates is spaced apart with guide holes for guide rods to pass through, the surface of the positioning plate is for multiple gears to be stacked, the lifting seat is connected to the surface of the fixed column, the support plate is slidably connected to the surface of the lifting seat facing the manipulator one, the sliding direction of the support plate and the axis of the guide rod are parallel to each other, the surface of the support plate can abut the bottom of the positioning plate and drive the positioning plate to slide along the axis of the guide rod in a direction close to the manipulator one, and the manipulator one clamps the gears stacked on the surface of the positioning plate in turn.

[0019] By adopting the above technical scheme, when the robot grips the gear in the positioning space and places it on the surface of the conveyor belt, the support plate surface abuts against the bottom of the positioning plate, and the support plate slides along the surface of the lifting seat toward the robot, driving the positioning plate to slide along the axis of the guide rod toward the robot, so that the next gear is at the height of the previous gear, thereby facilitating the robot to grip the gear in the positioning space. When multiple gears on the positioning plate are clamped to the surface of the conveyor belt in turn by the robot, the rotating ring is driven to rotate, driving the adjacent guide seats to approach the support plate, thereby realizing automatic feeding of the gears.

[0020] Optionally, the lifting seat includes a fixed part and a sliding part, the fixed part is connected to the top surface of the fixed column, the sliding part is slidably connected to the surface of the fixed part, the sliding direction of the sliding part and the sliding direction of the support plate are perpendicular to each other, and when the sliding part slides along the surface of the fixed part toward the direction close to the axis of the fixed column, the surface of the support plate separates from the bottom of the positioning plate.

[0021] By adopting the above technical scheme, when the rotating ring needs to rotate, the sliding part slides along the surface of the fixed part toward the direction close to the axis of the fixed column, and the axis of the support plate surface separates from the bottom of the positioning plate, so that the supporting effect of the support plate on the bottom of the positioning plate disappears, making it less likely for the rotating ring to be abutted and interfered by the support plate when rotating, thereby extending the service life of the fully automatic powder metallurgy gear shaping equipment; when the adjacent guide seat is located between the conveyor belt 1 and the support plate, the sliding part slides along the surface of the fixed part toward the direction close to the robot 1, and the support plate surface abuts against the bottom of the positioning plate to form support.

[0023] By adopting the above technical solution, when the gear is embedded in the positioning space, the elastic force of the elastic member drives the clamping piston to slide toward the positioning space, and the end of the protruding guide rod of the clamping piston presses against the outer peripheral surface of the gear to form a limit, making it difficult for the gear to shift in the positioning space, thereby further improving the stability of the gear limit in the positioning space.

[0024] Optionally, the clamping assembly further comprises a plurality of air supply pistons, a plurality of positioning pistons and a plurality of elastic members; a plurality of positioning cavities for sliding movement of the positioning pistons are spaced apart on the surface of the guide rod away from the positioning space; the positioning cavities correspond one-to-one with and are connected to the clamping cavities; the sliding direction of the positioning pistons and the sliding direction of the clamping pistons are parallel to each other; the positioning pistons correspond one-to-one with the air supply pistons; an air supply cavity for sliding movement of the air supply pistons is formed on the inner wall of the positioning cavity; one end of the elastic member in the elastic force direction is connected to the inner wall of the air supply cavity; the other end of the elastic member in the elastic force direction is connected to the surface of the air supply piston; The second elastic member has elastic force to drive the air supply piston to slide in the direction close to the positioning cavity, and the end of the air supply piston tends to protrude from the inner wall of the positioning cavity. The surface of the guide rod facing the positioning space is provided with an exhaust flow channel, and the exhaust flow channel connects multiple air supply cavities. When the pressing piston slides in the direction close to the positioning space, it drives the positioning piston to slide in the direction close to the pressing cavity. The surface of the positioning piston abuts against the surface of the air supply piston and drives the air supply piston to slide in the direction close to the air supply cavity, driving the air in the air supply cavity to be discharged from the exhaust flow channel and impact the gear surface in the positioning space.

[0025] By adopting the above technical scheme, when the support plate surface abuts against the bottom of the positioning plate and drives the positioning plate to slide toward the direction close to the manipulator, the clamping effect of the gear on the clamping piston disappears, and the elastic force of the elastic member drives the clamping piston to slide toward the direction close to the positioning space, the air pressure in the clamping chamber is reduced, the clamping chamber is connected to the positioning chamber, and the external air pressure drives the positioning piston to slide toward the clamping chamber. The surface of the positioning piston abuts against the surface of the air supply piston and drives the air supply piston to slide toward the direction close to the air supply chamber, the air pressure in the air supply chamber increases, and the air supply chamber is connected to the exhaust flow channel. The air in the air supply chamber is discharged through the exhaust flow channel and impacts the gear surface in the positioning space, so that impurities are not easily adhered to the outer peripheral surface of the gear, thereby realizing a preliminary self-cleaning action on the gear surface.
