A feeding device for steering gear ball joint pins Technical Field

[0001] This utility model relates to a feeding device, specifically a feeding device for a steering gear ball joint pin. Background Technology

[0002] Ball joint pins are intermediate components connecting steering gears to wheels. A ball joint pin includes a rod body and a ball head at the end of the rod body, the diameter of which is larger than the diameter of the rod body (see Figure 1). Ball joint pins are generally manufactured by casting a blank and then performing precision machining such as precision turning and thread cutting. Feeding the ball joint pins is required during precision machining. Patent application CN219131921U discloses a feeding device for ball joint pin processing, which includes a base. The top surface of the base has an L-shaped mounting seat that can move left and right. Inside the L-shaped mounting seat is a placement seat that can move up and down. The placement seat has several placement holes. Support rods are respectively provided at both ends of any end segment of the base's top surface on the front and rear sides of the L-shaped mounting seat. A top plate is provided on the top surface of the four support rods. A clamping device that can slide back and forth is provided on the bottom surface of the top plate. A connecting plate is provided on the two outermost support rods at the same end, and a grinding device is also provided on the connecting plate. This utility model can perform mechanical automatic feeding of ball joint pins through reliable tooling, thereby reducing the labor intensity of workers and increasing the working efficiency of the device.

[0003] The aforementioned feeding device can reduce labor intensity during the feeding process, but it requires manual insertion of each ball joint pin into the placement hole of the mounting base, which also leads to high labor intensity and low work efficiency. Therefore, it is necessary to redesign a feeding device for steering gear ball joint pins to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a feeding device for steering gear ball joint pins that can further reduce labor intensity and improve work efficiency.

[0005] The technical solution of this utility model is:

[0006] A feeding device for steering gear ball joint pins comprises a feeding mechanism, a vibration correction mechanism, and a gravity conveying box. The feeding mechanism is characterized by having a vibration correction mechanism at its top and a gravity conveying box on one side. The feeding mechanism consists of a storage bin, a plate chain conveyor belt, and pallets. The plate chain conveyor belt is mounted on the storage bin, with its bottom end extending obliquely into the bottom of the storage bin. Pallets are evenly distributed on both sides of the plate chain conveyor belt.

[0007] The pallets on both sides of the plate chain conveyor belt are staggered; a guide plate is provided on the plate chain conveyor belt above the pallets, and the top of the guide plate is sloping.

[0008] The vibration correction mechanism consists of a support plate, a vibrator, a chute, and a correction box. The chute is mounted on the support plate via the vibrator, and the correction box is fixedly mounted on the chute.

A vertical plate is provided on the side of the bottom plate opposite the plate chain conveyor belt, and a sealing plate is provided between the vertical plate and the bottom plate opposite the calibration box. The bottom plate is inclined from the side of the plate chain conveyor belt to the side of the vertical plate and from the side of the sealing plate to the side of the calibration box. The bottom plate is fixedly connected to the vibrator.

[0023] The feeding device for the steering gear ball joint pin consists of a feeding mechanism, a vibration correction mechanism, and a gravity conveying box 1. The vibration correction mechanism is located at the top of the feeding mechanism to correct the workpiece, ensuring the ball joint is facing upwards and the shaft is facing downwards, thus guaranteeing the workpiece's orientation when entering the finishing equipment. A gravity conveying box 1 is located on one side of the vibration correction mechanism to continue conveying the corrected workpiece into the finishing equipment. The feeding mechanism feeds workpieces one by one to the vibration correction mechanism. This individual feeding method, compared to manual placement, effectively reduces labor intensity and improves work efficiency.

[0024] The feeding mechanism consists of a storage bin 2, a plate chain conveyor belt 3, and pallets 4. The plate chain conveyor belt 3 is mounted on the storage bin 2, with its bottom end extending obliquely into the bottom of the storage bin 2. Pallets 4 are evenly distributed on both sides of the plate chain conveyor belt 3. The function of the storage bin 2 is to store workpieces and feed them using the stored workpieces. The function of the plate chain conveyor belt 3 is to rotate, driving the pallets 4 to move, thereby lifting and carrying the workpieces from the storage bin 2 to the vibration correction mechanism at the top end of the plate chain conveyor belt 3.

[0025] The pallets 4 on both sides of the plate chain conveyor belt 3 are staggered to transport workpieces one by one during the rotation of the plate chain conveyor belt 3, allowing each workpiece to enter the vibration correction mechanism sequentially and preventing blockage. A guide plate 5 is installed on the plate chain conveyor belt 3 above the pallets 4, with a sloping top. The sloping top of the guide plate 5 makes it difficult to lift and carry workpieces, while simultaneously generating a pushing force on the workpiece. Under this force, the workpiece is adjusted from a vertical or inclined state to a horizontal state, facilitating its rolling onto the pallet 4 for lifting and carrying.

[0026] The vibration correction mechanism consists of a support plate 6, a vibrator 7, a chute, and a correction box 8. The support plate 6 is equipped with the vibrator 7 (Ande brand ZDQ10 model), and a chute is mounted on the vibrator 7 to receive workpieces that fall under gravity after the plate conveyor belt 3 has passed its top. The workpieces are then transported via the chute. The correction box 8 is fixedly mounted on the chute to correct the workpieces transported by the chute, ensuring that the ball end of the workpiece faces upwards and the rod body faces downwards. The support plate 6 is fixedly connected to a support or wall in the surrounding environment. The vibrator 7 drives the chute and the correction box 8 to vibrate, thereby causing the workpiece to vibrate. This promotes the movement or rolling of the workpiece, facilitating its movement from the chute to the correction box 8, or facilitating the correction of the workpiece's orientation within the correction box 8.

[0027] The chute has an L-shaped cross-section and consists of a bottom plate 9, a vertical plate 10, and a sealing plate 11. The vertical plate 10 is located on the side of the bottom plate 9 opposite to the plate chain conveyor belt 3, and the sealing plate 11 is located between the vertical plate 10 and the bottom plate 9 opposite to the alignment box 8. The bottom plate 9 is inclined from the side of the plate chain conveyor belt 3 towards the side of the vertical plate 10 and from the side of the sealing plate 11 towards the side of the alignment box 8. The bottom plate 9 is fixedly connected to the vibrator 7. Due to the inclination of the bottom plate 9, after the workpiece falls onto the bottom plate 9, it first moves towards the junction of the bottom plate 9 and the vertical plate 10 under its own weight and vibration, preventing the workpiece from slipping between the plate chain conveyor belt 3 and the bottom plate 9. After the workpiece rolls to the junction of the bottom plate 9 and the vertical plate 10, it moves from the side of the sealing plate 11 towards the alignment box 8 under the action of the inclined plane and vibration, thereby transferring the workpiece from the chute to the alignment box.

[0028] The tops of the calibration box 8 and the gravity conveying box 1 are respectively provided with a groove 12, which is wider than the rod body and smaller than the ball head. The groove 12 of the calibration box 8 is connected to the groove 12 of the gravity conveying box 1. Baffles 13 are respectively provided on the calibration box 8 and the gravity conveying box 1 on both sides of the groove 12. Since the width of the groove 12 is greater than the rod body and smaller than the ball head, the workpiece rod body can pass through the groove 12, but the workpiece ball head cannot pass through the groove 12. Therefore, under the action of vibration and its own gravity, the workpiece rod body can pass through the groove and enter the calibration box 8, so that the rod body is downward and the ball head is upward, thereby correcting the orientation of the workpiece. After correction, the workpiece orientation is maintained during the transportation of the workpiece through the groove 12.

[0029] The alignment box 8 is tilted from the chute side to the gravity conveying box 1 side so that the workpiece can be conveyed from the alignment box 8 to the gravity conveying box 1 under the action of gravity and vibration.

[0030] The gravity conveying box 1 is curved, and a limiting plate 14 is provided on the top of the gravity conveying box 1 to limit the position of the ball head of the workpiece being conveyed in the gravity conveying box 1. In turn, the limiting plate 14 maintains the orientation of the workpiece, so that the workpiece is always in a state where the rod is downward and the ball head is upward during the conveying process.

[0031] When the feeding device of the steering ball joint pin is feeding, the framed workpiece is poured into the storage box 2 of the feeding mechanism. After the workpiece is poured in, the plate chain conveyor belt 3 of the feeding mechanism and the vibrator 7 of the vibration correction mechanism are started in sequence. After the plate chain conveyor belt 3 is started, it drives the guide plate 5 and the pallet 4 to move respectively. After the guide plate 5 guides the workpiece to a horizontal state, the pallet 4 lifts the horizontal workpiece. During the rotation of the plate chain conveyor belt 3, the workpiece is transported to the top end of the plate chain conveyor belt 3 through the pallet 4. After the workpiece passes the top end of the plate chain conveyor belt 3, it falls from the pallet 4 into the chute of the vibration correction mechanism under its own gravity. It falls onto the bottom plate 9 of the chute. Under the vibration of the inclined surface of the bottom plate 9 and the vibrator 7, the workpiece is transported from the chute to the correction box 8. The workpiece entering the correction box 8 is vibrated and passes through the slide 12 of the correction box 8 to enter the correction box 8, thus correcting the orientation of the workpiece. During the calibration process, the workpiece moves from the calibration box 8 to the gravity conveying box 1 under the tilting and vibration of the calibration box 8. After the workpiece enters the slide 12 of the gravity conveying box 1 through the slide 12 of the calibration box 8, it is conveyed into the interior of the finishing equipment under the action of the curved gravity conveying box 1, the limiting plate 14 and its own gravity, thus completing the feeding.

[0032] This steering gear ball joint pin feeding device can feed ball joint pins one by one via a feeding mechanism, eliminating the need for manual intervention. Compared to manually placing ball joint pins one by one, this effectively reduces labor intensity and improves work efficiency. A vibration correction mechanism guides the direction of the ball joint pins, ensuring consistent feeding direction and aligning the pin orientation with the process requirements of the precision machining equipment. This solves the problem of high labor intensity and low work efficiency caused by the need for manual placement of ball joint pins in existing feeding devices.
