[0029] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0030] As shown in the figure, an automated production line for cylinder liner processing includes multiple machining centers 1. Two sets of material conveying components are vertically arranged on one side of each machining center 1. The material conveying components include a hopper support 2 and a material placement plate 3. The material placement plate 3 is located on the top of the hopper support 2. A set of chain plate feeding components is arranged on both sides of the material placement plate 3. A ground rail 4 is arranged between the machining centers 1. The machining centers 1 are arranged along both sides of the ground rail 4. A robot mounting plate 5 is slidably connected to the top of the ground rail 4. A six-axis robotic arm 6 is mounted on the robot mounting plate 5. A set of processing and conveying components is arranged on both sides of the six-axis robotic arm 6. A gripper assembly for grasping cylinder liners is also provided at the end of the six-axis robotic arm 6.

[0031] Machining center 1 can perform corresponding processing on cylinder liners as needed. Machining center 1 is an automated device, which reduces manual operation and improves production efficiency to a certain extent. There are two sets of material conveying components, one set for loading and the other set for unloading. The hopper support 2 can provide support for the material placement plate 3, which can be used to place materials during transportation. The chain plate feeding component can be used for loading and unloading. The ground rail 4 and robot mounting plate 5 provide support for the installation of the six-axis robotic arm 6. The setting of the six-axis robotic arm 6 can facilitate the gripping of materials. Machining center 1 is set along both sides of the ground rail 4, so that the six-axis robotic arm 6 can feed materials into machining center 1 in sequence. The processing and conveying components can play the role of transporting and temporarily placing materials during the material processing process.

[0032] The chain plate feeding assembly includes a driving chain plate wheel 7, a driven chain plate wheel 8, a V-shaped transmission chain 9, a driving shaft 10, and a driven shaft 11. The driving chain plate wheel 7 is located at one end of the material placement plate 3 and is rotatably connected to the driving shaft 10. The driven chain plate wheel 8 is located at the other end of the material placement plate 3 and is rotatably connected to the driven shaft 11. The V-shaped transmission chain 9 is located between the driving chain plate wheel 7 and the driven chain plate wheel 8, and its two ends are rotatably connected to the driving chain plate wheel 7 and the driven chain plate wheel 8, respectively.

[0033] The drive chain wheel 7 can be driven to rotate by a drive assembly, such as a drive motor, motor sprocket, and roller chain. The drive chain wheel 7 rotates through the transmission of the drive motor, motor sprocket, and roller chain, and the driven chain wheel 8 is driven by the V-shaped transmission chain 9 to form a continuous conveying path. This ensures that materials such as cylinder liners can be stably and continuously conveyed to the designated position on the material placement plate 3. At the same time, the design of the V-shaped transmission chain 9 conforms to the shape of the cylinder liner, which facilitates the transportation of the cylinder liner. Compared with traditional conveying devices, it is less prone to falling off or deviating.

[0034] A slide rail 12 is provided on both sides of the surface of the ground rail 4. Several sliders 13 are slidably connected to the two slide rails 12. The top of the sliders 13 is fixed to the bottom of the robot connecting plate with bolts.

[0035] The slide rail 12 and the slider 13 work together to allow the robot connecting plate to slide on the surface of the ground rail 4, which in turn drives the six-axis robotic arm 6 to slide to the designated position, and then the material placed on the processing and conveying assembly is put into the corresponding processing center 1.

[0036] The processing and conveying assembly includes a support frame 14, a water receiving tray 15, a conveying bracket 16, and a supporting beam 17. There are two support frames 14, which are located on both sides of the top of the robot connecting plate. The top of the water receiving tray 15 is bolted to the conveying bracket 16, and its bottom is bolted to the two support frames 14. There are two conveying brackets 16, which are located on both sides of the water receiving tray 15. The two ends of the supporting beam 17 are bolted to the inner sides of the two conveying brackets 16. The top of the conveying bracket 16 is stepped, and multiple sets of material clamping components are provided on the top.

[0037] Two support frames 14 are respectively set on both sides of the top of the robot connection plate, providing a stable support foundation for the entire conveying assembly; the water receiving tray 15 is fixed to the conveying bracket 16 and the two support frames 14 by bolts, forming a stable support structure, and the support beam 17 enhances the connection strength between the conveying brackets 16; the water receiving tray 15 can collect liquids that may be generated during the conveying process, preventing them from dripping onto the robot or the work area, and keeping the working environment clean and safe; the top of the conveying bracket 16 is stepped and equipped with multiple sets of material clamping components, which enable the material to be stably clamped and conveyed, improving the accuracy and efficiency of processing.

[0038] The material clamping assembly includes a transition plate 18, a V-shaped clamping block 19, and a bearing 20. The transition plate 18 is bolted to the top of the conveying bracket 16, and its top is bolted to the V-shaped clamping block 19. There are two V-shaped clamping blocks 19, which are located at both ends of the transition plate 18. The bearing 20 is located on the top of the V-shaped clamping block 19.

[0039] The transition plate 18 provides support for the V-shaped clamping block 19, which can clamp the material. The six-axis robotic arm 6 moves horizontally during the material transport process. When the six-axis robotic arm 6 picks up the material from the V-shaped clamping block 19 or places the material from the machining center 1 onto the top of the V-shaped clamping block 19, the bearing 20 contacts the surface of the material and rolls, allowing the material to be moved horizontally, making it easier to pick up or put down the material.

[0040] Multiple limiting sheet metals 21 are bolted to one side of the conveying bracket 16; the limiting sheet metals 21 can prevent the material from falling off the V-shaped clamping block 19 during the process of being grabbed or put down by the six-axis robotic arm 6.

[0041] Several oil receiving trays 22 are provided on both sides of the top of the ground rail 4. An oil outlet hole is opened at both ends of the bottom of the oil receiving tray 22. A groove 23 is provided below two adjacent oil outlet holes. The groove 23 is bolted to the oil receiving tray 22.

[0042] The design of the oil tray 22 can directly receive liquids such as lubricating oil and coolant dripping from the six-axis robotic arm 6, the ground rail 4 or the cylinder liner, preventing these liquids from dripping directly onto the ground or the work area; the combined design of the oil tray 22 and the groove 23 can effectively collect and drain leaked oil, preventing the liquid from spreading in the work area, thereby maintaining a clean and safe working environment.

[0043] A flange connecting plate 24 is fixed to the end screw of the six-axis robotic arm 6. A gripper connecting plate 25 is screwed onto the flange connecting plate 24. An upper gripper fixing plate 26 and a lower gripper fixing plate 27 are provided on the side of the gripper connecting plate 25 away from the flange connecting plate 24. The upper gripper fixing plate 26 and the lower gripper fixing plate 27 are respectively bolted to the top and bottom of the gripper connecting plate 25. One gripper finger 28 is provided on the upper gripper fixing plate 26, and two gripper fingers 28 are provided on the lower gripper fixing plate 27.

[0044] Working principle: The cylinder liner is placed on the material placement plate 3 of the material conveying assembly. The cylinder liner is transported to the designated position by the active chain wheel 7, driven chain wheel 8 and V-type transmission chain 9 of the chain plate feeding assembly of the loading part. The six-axis robotic arm 6 grasps the cylinder liner with the gripper fingers 28 and stores it on the V-type clamping block 19. The six-axis robotic arm 6 moves to the designated position through the slide rail 12, slider 13 and robot connecting plate and other components, and puts the cylinder liner into the machining center 1. After the machining center 1 completes the processing, it is taken out of the machining center 1. The operation of putting in and taking out the cylinder liner from the machining center 1 is repeated multiple times until all processing steps are completed. The six-axis robotic arm 6 slides to the initial position and picks up the cylinder liner and puts it into the chain plate feeding assembly of the unloading part.
