Description

Technical Field

[0001] This application relates to the technical field of feeding structures, and in particular to a high-efficiency, lightweight, automatic feeding structure for friction welding. Background Technology

[0002] Friction welding machines utilize the heat generated by friction between workpiece contact surfaces to achieve welding. They mainly consist of a spindle system, a pressure system, and a control system. Their working principle involves the spindle driving the workpiece to rotate at high speed, bringing it into contact with another stationary workpiece and applying pressure. Under the action of friction, heat is generated on the contact surface, causing the material to reach a plastic state. Welding is then achieved under the action of upsetting force.

[0003] For light workpieces, manual loading is often used, where workers manually move workpieces such as pipes or rods onto the spindle fixture of the friction welding machine. For heavy workpieces, a trailer structure is often used, where the workpiece is placed on the surface of the trailer and transported to the side of the friction welding machine. With the assistance of other lifting structures, workers move the workpiece onto the spindle fixture of the friction welding machine.

[0004] In practice, manual assistance in feeding materials results in low feeding efficiency. Utility Model Content

[0005] To improve feeding efficiency and reduce manual intervention, this application provides a high-efficiency, lightweight, automatic feeding structure for friction welding.

[0006] The efficient and lightweight automatic feeding structure for friction welding provided in this application adopts the following technical solution:

[0007] A high-efficiency, lightweight, automatic feeding structure for friction welding includes a conveyor belt placed beside a friction welding machine. A support frame is slidably mounted on the side of the conveyor belt away from the friction welding machine. The support frame is positioned along the direction of approaching or moving away from the friction welding machine. A picking component is slidably mounted vertically on the support frame. The picking component includes a first cylinder, a carrier plate, a connecting plate, a gear, a rack, and a clamping plate. The first cylinder is rotatably mounted on the carrier plate with the center line of its rotation axis coinciding with the center line of the first cylinder itself. The first cylinder is horizontally positioned. One end of the connecting plate is fixedly connected to the outer wall of the first cylinder. The gear is rotatably mounted on the connecting plate. One end of the clamping plate is fixedly connected to the circumferential outer wall of the gear. One end of the rack is fixedly connected to the piston end of the first cylinder, and the rack meshes with the gear. Two gears and two clamping plates are provided and symmetrically arranged about the rack as an axis of symmetry.

[0008] By adopting the above technical solution, the conveyor belt is responsible for transporting lightweight workpieces to a position close to the friction welding machine, providing a basic path for workpiece transfer. Once the workpiece is transported to the appropriate position, the first cylinder is activated, and the piston drives the rack to move. Because the rack meshes with the gear, it drives the gear to rotate, causing the clamping plate fixedly connected to the gear to rotate accordingly. The two clamping plates are symmetrically arranged about the rack as an axis of symmetry, enabling the clamping and releasing of lightweight workpieces. In this way, replacing manual workpiece handling with a mechanical structure greatly improves loading efficiency, reduces manual intervention, and achieves the goal of automatic loading of lightweight workpieces. After the pick-up component clamps the workpiece, it moves vertically to a suitable height on the support frame. The support frame then moves towards the friction welding machine, facilitating the placement of the workpiece on the main shaft fixture of the friction welding machine.

[0009] Optionally, a first motor is fixed on the carrier plate, and the output end of the first motor is fixedly connected to the body of the first cylinder. The center lines of the first motor and the first cylinder are collinear. A bearing seat is provided on the carrier plate, and the first cylinder is placed on the bearing seat.

[0010] By adopting the above technical solution, in order to save floor space, all workpieces placed on the conveyor belt are placed vertically, such as steel pipes and rods. At this time, the first motor starts and can cooperate with the first cylinder to clamp the vertically placed workpieces. When the first motor starts, the clamped workpieces rotate to a horizontal state, which makes it easier to move them to the spindle fixture of the friction welding machine.

[0011] Optionally, a second cylinder is fixed on the support frame. The second cylinder is vertically arranged, and the piston end of the second cylinder is fixedly connected to the carrier plate.

[0012] By adopting the above technical solution, the vertically positioned second cylinder has its piston end fixedly connected to the carrier plate. The extension and retraction of the second cylinder can drive the carrier plate to move up and down vertically. When it is necessary to pick up light workpieces located at different heights, the second cylinder can adjust the height of the carrier plate to make the picking component reach the appropriate height, ensuring that the clamping plate can accurately clamp the workpiece. This enhances the adaptability of the feeding structure to different working conditions and improves the flexibility and efficiency of feeding.

[0013] Optionally, the support frame has an elongated hole, which is opened vertically, and the first cylinder passes through the elongated hole.

[0014] By adopting the above technical solution, the first cylinder can slide freely in the elongated hole when the second cylinder moves the carrier plate up and down. This provides guidance and space for the vertical movement of the first cylinder and the picking component, ensuring the stability and accuracy of the picking component's vertical movement, avoiding deviation during movement, and also saving the floor space occupied by the first cylinder.

[0015] Optionally, the support frame is provided with a slide rail on the side away from the conveyor belt, the length of the slide rail is set along the length direction of the conveyor belt, a third cylinder is provided on the support frame, a buckle plate is fixed to the piston end of the third cylinder, the buckle plate is fastened to the top of the slide rail and is slidably set along the length direction of the slide rail; the length direction of the third cylinder is along the direction close to or away from the friction welding machine.

[0016] By adopting the above technical solution, the position of the component being picked up can be adjusted horizontally towards or away from the friction welding machine through the extension and retraction of the third cylinder. This allows the component to move flexibly between the conveyor belt and the friction welding machine as needed.

[0017] Optionally, a second motor and a screw are provided on the top of the slide rail. The screw is arranged along the length of the slide rail. The second motor is fixed on the top of the slide rail and its output end is fixed to one end of the screw. The screw is rotatably mounted on the top of the slide rail and passes through the buckle plate. The screw is threadedly connected to the buckle plate.

[0018] By adopting the above technical solution, when the second motor starts, it drives the screw to rotate. Since the screw is threadedly connected to the buckle plate, the buckle plate causes the support frame to move precisely in a straight line along the length of the slide rail. By controlling the rotation direction and number of revolutions of the second motor, the moving distance and position of the support frame can be precisely controlled, achieving accurate positioning of the components being picked up. This further improves the automation and accuracy of the feeding structure, ensuring that lightweight workpieces can be accurately fed onto the spindle fixture of the friction welding machine, thus improving feeding efficiency and quality.

[0019] Optionally, the vertical cross-section of the slide rail is T-shaped.

[0020] By adopting the above technical solution, the vertical cross-section of the slide rail is T-shaped. This special shape design allows the buckle to be better fastened to the slide rail, preventing the buckle from falling off the slide rail during the sliding process, and enhancing the stability and reliability of the support frame when sliding on the slide rail.

[0021] Optionally, the buckle plate is provided with ball bearings, which roll and abut against the outer wall of the slide rail.

[0022] By adopting the above technical solution, the ball bearings set on the buckle plate roll against the outer wall of the slide rail, transforming the sliding friction between the buckle plate and the slide rail into rolling friction, which greatly reduces the friction force, making the buckle plate drive the support frame to slide more smoothly on the slide rail, reducing energy consumption, and also reducing wear between components.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Workpieces are transported by a conveyor belt, and a picking assembly consisting of a first cylinder, gears, racks, and clamping plates is used to automatically clamp and release lightweight workpieces, replacing manual operation and greatly improving loading efficiency. At the same time, the second cylinder drives the carrier plate to move vertically and the support frame to move horizontally along the slide rail, so that the picking assembly can flexibly transfer workpieces between the conveyor belt and the friction welding machine, reducing manual intervention and ensuring the high efficiency and automation of the loading process.

[0025] 2. The first motor, in conjunction with the first cylinder, can adjust the angle of the clamping plate to precisely clamp vertically placed workpieces and turn them into a horizontal position; the second motor drives the screw and engages with the buckle plate to achieve precise linear movement of the support frame on the slide rail, ensuring accurate positioning of the picked-up components and enabling the workpiece to be accurately placed on the spindle fixture of the friction welding machine; in addition, the second cylinder adjusts the height of the carrier plate, enhancing the structure's adaptability to workpieces of different heights and improving loading flexibility;

[0026] 3. The T-shaped slide rail and buckle plate design effectively prevents the support frame from falling off when sliding, ensuring operational stability; the ball bearings on the buckle plate convert sliding friction into rolling friction, reducing energy consumption, reducing component wear, and extending the service life of the equipment. At the same time, the elongated hole design saves space while ensuring stable movement of the components, making the entire feeding structure both practical and economical.

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] This application discloses a highly efficient and lightweight automatic feeding structure for friction welding.

[0033] refer to Figure 1A high-efficiency, lightweight, automatic feeding structure for friction welding includes a conveyor belt 1 placed beside a friction welding machine. The conveyor belt 1 is used to transport lightweight workpieces to a position close to the friction welding machine, providing a basic path for workpiece transport. A support frame 2 is slidably mounted on the side of the conveyor belt 1 away from the friction welding machine, and the support frame 2 can move in a direction close to or away from the friction welding machine. A picking component 3 is slidably mounted on the support frame 2 in a vertical direction.

[0034] refer to Figure 1 and Figure 2 The picking component 3 includes a first cylinder 31, a carrier plate 32, a connecting plate 33, a gear 34, a rack 35, and a clamping plate 36. The first cylinder 31 is rotatably mounted on the carrier plate 32, and the center line of its rotation axis coincides with the center line of the first cylinder 31 itself. The first cylinder 31 is horizontally positioned. One end of the connecting plate 33 is fixedly connected to the outer wall of the first cylinder 31. The gear 34 is rotatably mounted on the connecting plate 33. One end of the clamping plate 36 is fixedly connected to the circumferential outer wall of the gear 34. One end of the rack 35 is fixedly connected to the piston end of the first cylinder 31, and the rack 35 meshes with the gear 34. There are two gears 34 and two clamping plates 36, which are symmetrically arranged about the rack 35 as the axis of symmetry. Once the workpiece is conveyed to the appropriate position, the first cylinder 31 is activated, and its piston drives the rack 35 to move. Since the rack 35 meshes with the gear 34, it drives the gear 34 to rotate. The clamping plate 36, fixedly connected to the gear 34, rotates accordingly, achieving the clamping and releasing action of the lightweight workpiece, replacing manual workpiece handling. In this embodiment, the connecting plate 33 is Z-shaped, and the rack 35 passes through the connecting plate 33. The connecting plate 33 not only provides an installation position for the gear 34 but also provides a sliding path for the rack 35. Teeth are provided on the vertical sidewalls of both sides of the rack 35, thereby meshing with the gears 34 on both sides.

[0035] refer to Figure 1 and Figure 2 A first motor 4 is fixed on the carrier plate 32. The output end of the first motor 4 is fixedly connected to the body of the first cylinder 31, and the center lines of the first motor 4 and the first cylinder 31 are collinear. A bearing seat is also provided on the carrier plate 32, and the first cylinder 31 is placed on the bearing seat. In practical applications, to save floor space, all workpieces placed on the conveyor belt 1 are placed vertically, such as steel pipes and rods. When the first motor 4 is started, it can work with the first cylinder 31 to clamp the vertically placed workpieces. After clamping, the first motor 4 can rotate the workpiece to a horizontal position, facilitating its subsequent movement onto the spindle fixture of the friction welding machine.

[0036] refer to Figure 1 and Figure 2A second cylinder 21 is fixed on the support frame 2. The second cylinder 21 is vertically arranged, and its piston end is fixedly connected to the carrier plate 32. By extending and retracting the second cylinder 21, the carrier plate 32 can be moved up and down in the vertical direction. When it is necessary to pick up light workpieces located at different heights, the operator can control the second cylinder 21 to adjust the height of the carrier plate 32 so that the picking component 3 reaches the appropriate height, ensuring that the clamping plate 36 can accurately clamp the workpiece.

[0037] refer to Figure 1 and Figure 2 The support frame 2 has an elongated hole 22, which is vertically oriented. The first cylinder 31 passes through the elongated hole 22. This design allows the first cylinder 31 to slide freely within the elongated hole 22 when the second cylinder 21 moves the carrier plate 32 up and down. This provides guidance and space for the vertical movement of the first cylinder 31 and the picking component 3, while also saving the floor space occupied by the first cylinder 31.

[0038] refer to Figure 2 and Figure 3 A slide rail 5 is provided on the side of the support frame 2 away from the conveyor belt 1, and the length of the slide rail 5 is set along the length direction of the conveyor belt 1. A third cylinder 23 is provided on the support frame 2, and a buckle plate 7 is fixed to the piston end of the third cylinder 23. In this embodiment, the buckle plate 7 is C-shaped. The buckle plate 7 is fastened to the top of the slide rail 5 and is slidably set along the length direction of the slide rail 5. The vertical cross section of the slide rail 5 is T-shaped. This special shape design allows the buckle plate 7 to be better fastened to the slide rail 5 and prevents the buckle plate 7 from falling off the slide rail 5 during sliding. The buckle plate 7 is provided with ball bearings 6. The ball bearings 6 roll and abut against the outer wall of the slide rail 5, changing the sliding friction between the buckle plate 7 and the slide rail 5 into rolling friction, reducing the friction force. The length direction of the third cylinder 23 is along the direction close to or away from the friction welding machine. By extending and retracting the third cylinder 23, the support frame 2 can slide on the slide rail 5, thereby adjusting the position of the picking component 3 in the horizontal direction to be closer to or further away from the friction welding machine. This allows the picking component 3 to move flexibly between the conveyor belt 1 and the friction welding machine according to actual needs.

[0039] refer to Figure 2 and Figure 3 A second motor 51 and a screw 52 are installed on the top of the slide rail 5. The screw 52 is positioned along the length of the slide rail 5. The second motor 51 is fixed to the top of the slide rail 5, and its output end is fixed to one end of the screw 52. The screw 52 is rotatably mounted on the top of the slide rail 5. The screw 52 passes through the buckle plate 7 and is threadedly connected to the buckle plate 7. When the second motor 51 is started, it drives the screw 52 to rotate. Because the screw 52 is threadedly connected to the buckle plate 7, the buckle plate 7 drives the support frame 2 to make precise linear movements along the length of the slide rail 5.

[0040] The implementation principle of the efficient and lightweight automatic feeding structure for friction welding according to an embodiment of this application is as follows: First, the conveyor belt 1 transports the lightweight workpiece to the designated position. Then, the second cylinder 21 is activated to adjust the height of the carrier plate 32 so that the picking component 3 reaches a position suitable for the height of the workpiece. The first cylinder 31 is activated, and through the transmission of the rack 35 and the gear 34, the clamping plate 36 clamps the workpiece. Next, the first motor 4 is activated to rotate the vertically clamped workpiece to a horizontal position. Afterward, the third cylinder 23 extends and retracts, driving the support frame 2 to move on the slide rail 5, so that the picking component 3 is close to the friction welding machine. At the same time, the second motor 51 drives the screw 52 to rotate, precisely adjusting the position of the picking component 3. Finally, the workpiece is accurately placed on the main shaft fixture of the friction welding machine, completing the automatic feeding process. The entire process reduces manual intervention, improves feeding efficiency, and has a stable, reliable, and highly adaptable structure.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
